When it comes to the buying decision for solar inverters, some buyers might be inclined to only look at pricing and spec sheets. While these are certainly buying criteria that should not be neglected, it is just a small portion of the bigger picture that needs to be looked at when choosing an inverter brand – because an inverter is more than what’s in the box.But why should you even consider Fronius Solar inverter?

As the solar inverter industry is becoming more commodified every year, inverter spec sheets are starting to look a lot more similar. Many inverter capabilities are driven by the same market requests and NEC code regulations, making features and pricing very similar across all inverter brands in the market. Therefore, a buyer could think that the only thing to look at is the price tag. However, it’s crucial to actually look past the spec sheet and the initial purchase price. When picking an inverter, you not only chose a piece of equipment, you are choosing a partner to work with for the next 20+ years. Thus, you might want to look into more than just “the box” and its price.

So what specific buying criteria is there beyond specs and price? The inverter is a critical component of a solar system, as it is not just responsible for DC to AC conversion, but also for the safety of a system, maximum power point tracking, grid interconnection and system monitoring. It is obvious that the inverter and its performance have a big impact on a system’s Levelized Cost of Energy (LCOE) and profitability – inverter uptime, operation & maintenance (O&M) programs and warranty matter in that regard, and this is where the company behind the inverter plays a crucial role.

When choosing an inverter partner for the long term, it is crucial that this partner is around beyond the lifetime of a system. Therefore, financial stability and bankability, as well as a global footprint with a local support infrastructure are key aspects to look at. There is no doubt that the fairly fragmented inverter market will see further consolidation, given the ongoing price pressure. This increases the risk of certain manufacturers going out of business and leaving both installers and system owners in the lurch.

Furthermore, an easy to reach manufacturer support hotline and personal, long-lasting relationships on manufacturer’s level help installers through the entire process from designing systems to after-sales service for 20+ years – ensuring uptime and quick service. Since all power electronics can fail at some point, customer-friendly warranty terms and an easy RMA process are making a big difference. Power electronics manufacturers from advanced industries even offer spare part kits among certifications for contractors to conduct repairs cost-effectively in the field and within one truck-roll – a big impact on the profitability of a system.

All these aspects make a big difference and cannot be found on a spec sheet or on the price tag. Make a smart choice. Do not just look at the spec sheet and the price tag, when picking your  solar inverter. It’s a decision that will impact you over the next 20+ years and you want to be sure that your considerations are aimed at this period of time too.That is why Fronius solar inverters is a great choice.

Ghana:Organizations to shift to solar net metering system

Mr Kwabena Otu Danquah, the Head of Renewable Energy Promotion of the Energy Commission, has advised organisations to shift to the solar net metering system to save them from getting into the higher consumption rate bracket.

 

He said net metering was a mechanism that fed the national grid with surplus solar energy from households while assisting them to save cost and urged consumers to take advantage of it.

Mr Danquah was speaking at a two-day solar industry workshop in Accra organised by the Netherlands Development Organisation (SNV) and the Association of Ghana Solar Industries (AGSI) on current initiatives and opportunities in Ghana’s energy sector.

He said the Energy Commission, in collaboration with the Electricity Company of Ghana, had installed 35 net metering systems in various homes in Accra on a pilot basis.

“We are waiting for the Public Utilities Regulatory Commission (PURC) for the gazette to ensure that the new solar metering system fully takes off in Ghana,” he said.

Mr Danquah said the Energy Commission had created the enabling environment to ensure the attainment of enough renewable energy targets by 2020.

He said by the provision of the Renewable Energy Act 2011, 832, the Energy Commission, in collaboration with the Ghana Standards Authority, would enforce the law on the importation of renewable energy products that would meet good standards and certification.

He said: “The solar technology we know are perfect but the installation is the problem, hence the need for the Energy Commission to license all electricians and develop a training curriculum to train technicians to ensure good certification of solar.”

Mr Emmanuel Aziebor from the Netherland Development Organisation, a resource person, urged stakeholders in the solar industry to come out with substantive business models to convince the microfinance companies to invest in solar energy.

He advised the technical experts to support and sustain the technology whilst training more technicians on it.

Mr Aziebor said: “We need to have people prepared, trained and exposed to solar energy while looking at the local production of the products in future.”

Mr Eric Omane Acheampong, the President of AGSI, advised the members to develop activities on networking to enable them to assess their progress while sharing knowledge.

Mr James Robinson, the SNV Leader for Energy Sector, Ghana, gave the assurance that the SNV would continue to facilitate the activities of AGSI to sustain and promote solar energy in the country.

I am not that kind of a man, but I have been in the company of other men who in the midst of challenges rather saw them as opportunities to change the paradigm.

I strongly believe that very few energy planners and experts would disagree that Energy Independence for Ghana is an important, even urgent, goal.

But the question remains, is shifting the energy paradigm realistic; and if so, how?

And do our politicians and related institutions have the needed passion and spirit to embrace the new paradigm in our energy sector?

In recent years it has become so glaring that the conventional energy paradigm (fossil fuel tradition) has rapidly lost ground in comparison to the concept of Sustainable Development, as it is based on the intensive use of non-renewable fossil fuels — causing environmental degradation and posing Global Energy Security Risks.

Thus, a modification in our energy paradigm is necessary for our energy independence. A paradigm shift in the goals of energy policy should take place: toward independence, security of supply and climate change. Transition to a sustainable energy system is one of the critical challenges humankind faces in achieving energy independence in the new millennium.

Ghana is a country that has unbelievable solar energy potential; but, sadly, solar energy sources contribute only 0.1% (on-grid+ off-grid) of the total installed capacity for the total installed power capacity of 2104.5 MW in Ghana. (VRA: Facts & Figures).

Some people may say I am overly obsessed with the idea of solar energy for our small but incredibly energy-resource-rich nation.

It’s true – I am! But is it practical for Ghana to actually pursue this objective?

Talking of our potential, Wa — capital of the Upper West Region — has the highest level of solar irradiation (5.524 KWh/m2-day) across the country.

May is the month with the highest solar irradiation (5.897 KWh/m2-day), with August recording the lowest measurement (4.937kWh/m2-day) in Wa.

Akim Oda, conversely, is the location that records the lowest radiation (4.567kWh/m2-day) measurements across the country.

The highest measurement in Akim Oda was recorded in the month of April (5.176kWh/m2-day) and the lowest in August (3.802kWh/m2-day). See Table 1. 

As a nation we are blessed with daily sunshine that averages 5 hours, which ranges between about 7 hours and 4 hours for the northern and southern regions of the nation respectively. Ghana also has annual average daily solar radiation of about 4.5 to 5 KWm2/day.

Assuming we are to use only 23,854km² which is 10% of the total land area (238,585 km²) of Ghana to harness the sun’s energy with PV panels of 15% conversion efficiency, then Ghana would harvest 4,114 TerraWattHours of energy per year. 

This amount is equal to 2.42billion barrels of oil.

Consequently, if we juxtapose this amount with our current oil production in the Jubilee Field, then it is about 27 times the current crude oil production of Ghana per year.” See Chart A on Ghana PV Output.

In Ghana, Solar PV applications are gradually receiving acceptance in most places. However, despite improvements in local Research and Development (R&D) efforts, the body of knowledge on these technologies and their market potentials is considerably inadequate.

Launching major national initiatives on these technologies — such as the President’s 200,000 solar rooftops for households — requires a robust knowledge base and capacity.

In all, PV technologies are showing increasing promise in terms of efficiency improvements and cost. The estimated lifetime of PV modules are 25 years, and this makes them exceptionally attractive for investors.

Today, except for the Solar PV Panels produced in Kpone-Tema by Strategic Power Solutions (SPS) — a subsidiary of Strategic Security Systems International Limited, almost 80% the PV modules on the Ghanaian market are imported.

Solar PV systems can be extensively used for a wide range of electrical energy requirements: including solar home systems, water pumping, refrigeration and telecommunications that will reduce the load curve of electricity demand.

It has been estimated that solar rural electrification is about 30% cheaper than the cost of grid extension to rural communities that are about 18 to 20km from the nearest grid station.

However, there are still economic and institutional obstacles that limit this ability to self-generate power. For instance, while it is practical to install solar panels on a home, it is more difficult to scale-up these systems for commercial and industrial-sized projects. Scale is a critical issue in energy generation, as with scale comes lower project costs and greater efficiency.

For privately distributed generation projects, both small and large, to make greater contributions toward our national energy independence, there needs to be continued evolution of the bold policies that first introduced grid-connection rights and net metering in our renewable energy act.

The government must as a matter of urgency assist all consumers anywhere in the country to benefit from the net-metering incentive for solar power consumers. Again, due to the high upfront cost, government must establish a renewable energy revolving credit fund whereby solar consumers can borrow money to finance solar systems without making large up-front payments and without paying high interest rates to banks or private financiers.

Also, the PURC must establish a coherent pricing tariff for distributors to buy power from private solar-farm developers. This could unlock an untapped source of clean, reliable, economical power for Ghana.

While not easy to accomplish, these advances are achievable – and, importantly, they don’t need to cost the tax payers any money. However, they depend on the political will and leadership of our energy-sector authorities.

This an original story by Maxmillian Kwarteng and has been featured on BFT online


Apparently the economics for backup power alone just aren’t that attractive.

Tesla has quietly removed all references to its 10-kilowatt-hour residential battery from the Powerwall website, as well as the company’s press kit. The company’s smaller battery designed for daily cycling is all that remains.

The change was initially made without explanation, which prompted industry insiders to speculate. Today, a Tesla representative confirmed the 10-kilowatt-hour option has been discontinued.

“We have seen enormous interest in the Daily Powerwall worldwide,” according to an emailed statement to GTM. “The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home. Due to the interest, we have decided to focus entirely on building and deploying the 7-kilowatt-hour Daily Powerwall at this time.”

The 10-kilowatt-hour option was marketed as a backup power supply capable of 500 cycles, at a price to installers of $3,500. Tesla was angling to sell the battery to consumers that want peace of mind in the event the grid goes down, like during another Superstorm Sandy. The problem is that the economics for a lithium-ion backup battery just aren’t that attractive.

Even at Tesla’s low wholesale price, a 500-cycle battery just doesn’t pencil out against the alternatives, especially once the inverter and other system costs are included. State-of-the-art backup generators from companies like Generac and Cummins sell for $5,000 or less. These companies also offer financing, which removes any advantage Tesla might claim with that tactic, as GTM’s Jeff St. John pointed out last spring.

“Even some of the deep cycling lead acid batteries offer 1,000 cycles and cost less than half of the $3,500 price tag for Tesla Powerwall,” said Ravi Manghani, senior energy storage analyst at GTM Research. “For pure backup applications only providing 500 cycles, lead acid batteries or gensets are way more economical.”In Ghana  good  quality lead acid batteries such as the AGM telecom batteries retail at $219/Kw/hr and can be purchased at nocheski Solar (Victron Energy partner ) in the port city of  Tema. These AGM batteries have 1800 cycles at a D.O.D of 30% or 750 cycles at a D.O.D of 50%

In California, batteries can benefit from the state’s Self-Generation Incentive Program (SGIP). But California regulators have indicated that battery systems need to be able to cycle five times a week in order to be eligible, which would exclude Tesla’s bigger battery.

“In current discussions on SGIP program overhaul, it is very likely that stronger performance requirements may get added, which will make a 10-kilowatt-hour/500 cycles product outright ineligible (if cycled only once a week), or last only 2 years (if cycled every weekday for about 500 cycles over 2 years),” said Manghani. “In short, the market’s expectation is that for a $3,500 price tag, the product needs to have more than just 500 cycles (i.e., only backup capabilities).”

Backup power alone simply doesn’t have as strong a case as using a battery for self-consumption. That said, the opportunities for self-consumption are still few and far between.

A GTM Research analysis for residential storage, purely for time-of-use shifting or self-consumption. found that the economics only pan out in certain conditions. In Hawaii, for instance, the economics of solar-plus-storage under the state’s new self supply tariff looks only slightly more attractive than solar alone under the grid supply option.

“So it comes down to the question of customer adoption of a relatively new technology for only slightly improved economics,” said Manghani. “This doesn’t mean residential customers are not deploying energy storage,” but he noted that these were the early adopters.

Tesla appears to be focusing its efforts on first movers and the markets where storage for energy arbitrage and self-consumption makes economic sense.

While the 10-kilowatt-hour option has been removed, the Powerwall website continues to offer specifications for Tesla’s 6.4-kilowatt-hour battery designed for daily cycling applications, such as load shifting. The battery is warrantied for 10 years, or roughly 5,000 cycles, with a 100 percent depth of discharge. The wholesale price to installers is $3,000.

The smaller battery is often marketed as 7 kilowatt-hours, which would appear to have a price of $429 per kilowatt-hour. In realty, it’s a 6.4 kilowatt-hour battery at a price of $469 per kilowatt-hour.

A bigger, cheaper or more integrated battery product could soon be added to Tesla’s lineup. In January, CEO Elon Musk announced a new Powerwall option will be released this summer.

“We’ve got the Tesla Powerwall and Powerpack, which we have a lot of trials underway right now around the world. We’ve seen very good results,” said Musk during a talk to Tesla car owners in Paris, The Verge reports. “We’ll be coming out with version two of the Powerwall probably around July, August this year, which will see [a] further step-change in capabilities.”

At this point, it’s unclear what the “step-change” will be.

 

 


Why your Lead Acid Battery is all Swollen Up

Working in the solar Energy industry in Ghana, I often come across several batteries that are swollen up .These mostly lead acid batteries have often than not, been purchased at very high prices not too long ago. On this particular occasion our team was conducting a survey at a prospects home in Tema when I noticed that all of her eight 100Ah batteries were swollen.

Typically a 100Ah battery will cost between $200-$300 depending on quality .In addition to this, most suppliers in Ghana give little or no warranty even though some global brands like Victron Energy give up to two year warranty on their batteries .This article aims to reveal to the public why lead acid batteries swell-up and how to avoid the problem.

Sealed lead acid batteries – both AGM and gelled electrolyte can swell up and expand sometimes. This happens due to the construction of lead acid batteries which is referred to as “recombinant”. They are constructed in such a way to allow absorption of gasses released during the chemical process inside the battery.

The positive and negative plates are placed very close together with only the thickness of the divider separating them. They are tightly secured in the cell cavity resulting in very little extra space inside the battery. When the cell plates expand, it exerts pressure on the inside walls of the battery. This situation can cause the battery case to swell resulting in possible splits and cracks at various points of the battery.

Why Do Battery Cell Plates Expand?

The cell plates most often expand due to overcharging of the battery. The battery may also expand due to shorting of the terminals of the battery. Both these situations results in heating up of the cell plates inside the battery. The lead of the cell plates has a high expansion rate when heated.

The outcome is that the battery experiences extreme pressure inside that swells up and deforms it. The swelling-up of the battery may also cause great damage to the internal components and parts.

Why your Lead Acid Battery is all Swollen Up ,How to Avoid Swelling Up of the Battery?

Overcharging or short-circuiting of the battery is the only reason for swelling up of the lead acid battery. The problem is not inherent in the battery itself. In order to avoid swelling up of the battery you need to tackle the underlying cause of the problem.

You need to follow proper instructions in charging the battery. The culprit may be that you are using a wrong charger when charging the battery. If the charger is providing too much current, this may be the cause for battery swelling up. For instance, if you used 24V charger to charge a 12V battery it will most probably result in overcharging of the battery.

Whatever the reason for overcharging of the device, the end result is the swelling up of the battery. To avoid the prospect of overcharging or short-circuiting of the battery, you need to take the following precautions:

  • Use the right type of charger that is fully compatible with the battery.
  • Ensure proper polarity when connecting the charger to the battery
  • Shield the battery terminals to avoid short-circuiting of the battery
  • Use a charger whose maximum charging capacity is lower than the battery
  • Using a good quality charger

 Battery charging tip: increase battery life with Victron 4-step adaptive charging

Victron developed the adaptive charge curve. The 4-step adaptive charge curve is the result of years of research and testing.

The Victron four-step adaptive charge curve solves the 3 main problems of the 3 step curve:

  • Battery Safe mode

In order to prevent excessive gassing, Victron has invented the ‘Battery Safe Mode’. The battery Safe Mode will limit the rate of voltage increase once the gassing voltage has been reached. Research has shown that this will reduce internal gassing to a safe level.

  • Variable absorption time

Based on the duration of the bulk stage, the charger calculates how long the absorption time should be in order to fully charge the battery. If the bulk time is short, this means the battery was already charged and the resulting absorption time will also be short, whereas a longer bulk time will also result in a longer absorption time.

  • Storage mode

After completion of the absorption period the battery should be fully charged, and the voltage is lowered to the

float or standby level. If no discharge occurs during the next 24 hours, the voltage is reduced even further and the battery goes into storage mode. The lower storage voltage reduces corrosion of the positive plates.

Once every week the charge voltage is increased to the absorption level for a short period to compensate for selfdischarge (Battery Refresh mode

The above tips will help you to protect your battery from swelling up and expanding. Taking precautions will not only protect your battery from being damaged but it will also minimize the threat of fire caused due to overheating of the battery.

“Just  2% of Ghana’s land can provide 924GWh of power annually” ( Maxmillian Kwarteng  ,Gramax Energy Group)

Before I begin, permit me to ask this, if Oil and Gas for Thermal Power Plants and the other fossils are that “Cheap” as some want us to believe, why then are electricity rates still going up?Every hour, the sun radiates more energy onto our earth than the entire human population uses in one whole year. The technology required to harness the power of the sun is available now. Solar power alone could provide all of the energy Ghanaians consume and there is no shortage of solar energy like there has been with the Akosombo Dam in recent days. The truth is, we do not need advanced math skills to follow and perform the solar arithmetic to prove that Ghana’s energy independence could be achieved with solar energy.

Every square meter (1m²) of the earth’s surface, when exposed to direct sunlight, receives about 1000 watts (1 kilowatt) of energy from the sun’s light. In reality, this power per hour for every square meter (1m²) might be more or less, depending on the angle of sunlight, which changes with the time of day, and the geographical location. On average, the sub Saharan region of Africa receives about (3 – 4 kilowatt per hour) of solar energy.

Nonetheless, studies have revealed promising potential for this resource in Ghana. According to the SWERA Ghana Project report, Wa, the capital of the Upper West region, has the highest level of solar irradiation (5.524 KWh/m2-day) across the country. May is the month with the highest solar irradiation (5.897 KWh/m2-day), with August recording the lowest measurement (4.937kWh/m2-day) in Wa. Akim Oda on the contrary is the location that records the lowest radiation (4.567kWh/m2-day) measurements across the country. The highest measurement in Akim Oda was recorded in the month of April (5.176kWh/m2-day) and the lowest in August (3.802kWh/m2-day).

This estimate tells that sunlight will provide useful solar energy for about 4 to 6 hours per day because during the early hours and late hours of the day the angle of the sun’s light is too low.Therefore, let us assume for every square meter (1m²) exposed to continuous direct sunlight [in an optimal geographical location] for an average of 4.5 hours a day, we will have received 4.5 hours x 1000 watts = 4500 watthours (4.5kwh/m²) of solar energy during the course of a day. It would be great if 100% of the sunshine became electricity, but solar energy and electricity are not the same. Technology accomplishes the conversion of solar energy to electricity.

Conversion of one form of energy to another always causes a loss of energy. In other words, the new form of energy will be less than the original. Efficiency is the word used to describe the difference in power resulting from the conversion of one form of energy to another. The efficiency of commercially available solar panels (PV) is now between 15% – 40.7%. This means that when a solar panel converts the sun’s light to electricity, only about 15 to 40.7 percent of the energy in the sunlight becomes electricity. The same thing is true of gasoline in your car and other thermal engines. Your car’s engine can only convert about 25 percent of the energy in gasoline to mechanical energy that turns the wheels.

With an average efficiency of 15 to 40.7 percent, every square meter (1m²) of solar photovoltaic cells (PV) would produce (4.5 kilowatthours of solar energy multiplied by 15% =) between 0.68 kilowatthours of electric energy per day.

Solar panels (PV) covering an area of 100m²(1 Plot of Land) would produce 100 x .68 = 68 kilowatthours of electricity per day. It is worth noting that 68kwh per day is a lot of electricity for a single family home.

 

Let’s juxtapose this arithmetic nationwide to the unused land surface:

– Size of Unreserved forest land in Ghana = 5 x 10³km² è 5 x 10⁹m².

– Assuming a Conversion Efficiency (Solar Panels) of 15%.

– Average Solar Irradiation 4.5kilowatthours (kwh) è 4500wh/day

– Annual average solar radiation = 4.5 x 365 è 1642.5kwh/m².y

– Assuming a Performance ratio, coefficient for losses of 0.75

So, 0.15 x 1642.5kwh/m².y x 5 x 10⁹m² x 0.75  è 923.9Gwh/y

Like in Germany where Solar energy powered 50% of its midday electricity needs on May 26, 2012, this amount of energy can be used for same in Ghana.It is interesting to note that this amount of energy has been calculated from an area of 5,000km² which is only 2% of the total surface area of Ghana.In 2004, Ghanaians consumed 5,158 gigawatthours (GWh) of electricity. NEDCO alone contributed 340GWh out of this figure. This contribution from NEDCO is only one third of my estimate of the calculated solar potential. It is estimated that about half of this amount is consumed by domestic (or residential) consumers for household uses such as lighting, ironing, refrigeration, air conditioning, television, radio and the like.

In conclusion, let me say that the improved technology surrounding solar power is very significant. It has brought clean energy within practical use. Given the significant environmental benefits, there is a very strong case for government intervention to accelerate the switch to solar power. The reluctance to switch to solar power is delaying our national progress in living standards.

100 MW Ghana Solar Farm Gets Funding

Home Energy Africa, which specializes in the development and sales of renewable energy products for businesses, governments, and residential homes in Africa, has obtained a $705,000 grant from the US Trade and Development Agency (USTDA) for the development of a solar PV power generation project in Ghana.

Projected to begin construction in 2017, ESI Africa reports that this solar project will generate 100 MW of power, providing electricity to approximately 80,000 average homes in the country.

The agreement between the two countries was signed by Robert P. Jackson, the US Ambassador to Ghana, and Charles Sena Kwadzo Ayenu, CEO of Home Energy Africa.

“Lack of power is a challenge we see across sub-Saharan Africa. Two out of three people in this region lack access to electricity. That hinders business, and it hinders prosperity. We’ve made increasing access to power one of the top priorities for our bilateral relationship. Today’s grant is just one more way we’re bringing together government and the private sector to make Ghana’s future brighter,” said Jackson.

Boosting the Supply of Electricity

“One of Ghana’s paramount constraints to sustainable economic growth is the country’s inadequate electric power supply. This grant will support us in bringing our solar power PV project to financial close in order to fill the gap in power supply, meet Ghana’s goals for clean and sustainable energy, help create over 200 jobs to local communities and provide electricity to at least 80,000 average homes in Ghana,” said Mr. Ayenu.

Ayenu stated Ghana presently has 2,450 MW of installed capacity, adding: “The government of Ghana aspires to double that capacity to 5,000 MW this year, including 10% from renewable sources.”

The USTDA grant targets providing technical assistance to Home Energy Africa by using GreenMax Capital Advisors, an American firm, in finalizing the legal and financial details necessary to implement the project. Project assistance includes preparation for power purchase agreement negotiations with the Electricity Company of Ghana, services contracts, and financial arrangements.

Ayenu said the signing of the grant was the last barrier that the company has had to cross for work to begin on the project. He added that the firm has also acquired a 30% equity funding agreement for the $150 million project.
