The latest innovation comes from Japan’s Sanyo Electric Company who has developed the a very impressive new PV technology which works like this HIT solar cells improve boundary characteristics and reduce power generation losses by forming impurity-free i-type amorphous silicon layers between the crystalline base and p- and n-type amorphous silicon layers.

The first of many projects I’m sure to use the HIT solar cells is a project in Italy. The Project funded by a consortium led by Deutsche Bank is expected to be completed by September 2010.
Sanyo’s HIT solar cells, which are famous for their high-conversion efficiency, are now well on their way to improving PV module production and reducing cost for manufacturing. Thanks to the use of HIT solar cells, soon there will be feasibility of excellent-quality power production. This increase in the amount of quality-power generation of HIT solar cells makes the HIT solar cells a hard competitor to follow by traditional PV manufacturers.

The hybrid Sanyo HIT cells, are made from thin mono-crystal silicon surrounded by ultra-thin amorphous silicon are now more cost efficient both production-wise as well as raw-materials-wise. Reduction in the optical absorption loss and reduction in resistance loss make the Sanyo HIT Photovoltaic Modules the ideal choice in most installations.
HIT solar cells have been successful in small-sized systems now with the Italian installation we will see how they are for larger buildings/complexes.

Senior Development Manager, Dean Konstantine from Green Go Solar, LLC announces the company has received a clean bill of health from its consultants who have completed the required environmental impact study on the 160 acres owned by Green Go Solar. The property is located North of Victorville, California and has been set aside for development into a 35 megawatt solar PV farm designed to proved 100% renewable carbon free energy to Southern California Edison through a Power Purchase Agreement. The report put the company one step closer to the realization of the project becoming a reality.

Sunjoy Energy, a Milwaukee based alternative energy consulting firm who was contracted by Green Go Solar to complete a through and required Environmental Assessment report on the 160 acres prior to the permit process, has returned a clean bill of health and a green light to move forward with application for a conditional use permit from the county of San Bernardino.

Negotiation are currently underway between company owners, Dr. William Abboud, Richard Abboud and Dean Konstantine with several private funding sources who have committed to providing the capital investment needed to complete the 35 megawatt project. The company hopes to have the project completed by year end 2011, if completed on schedule this project would become the largest alternative energy, zero carbon based, solar electric generator in the US.

Lead development manager Dean Konstantine, is working on his innovative co-generation technology and megawatt storage cylinders, which once on line would be incorporated into this project and future alternative energy developments giving them the sustainability currently lacking in most alternative energy sources.

Most consumers are not aware they could for instance be paying for 200 Watt solar panels while only getting 180 Watt out of those same solar panels! This discrepancy is known as “peak tolerance rating” (PTC Rating) in some cases known as “minimum warranted power “or” negative tolerance rating. When shopping for solar panels, what you want to look for is the highest minimum warranted power rating, the lowest negative tolerance rating or the lowest peak negative tolerance (PTC) rating.
A solar panel manufacturer may claim their panels have a high efficiency rating but their claim maybe worthless if the solar panel has a poor minimum warranted power or a low (PTC) rating. What all this means is that the solar panel manufacturer offers a warranty that states that their solar panel’s actual power rating will not be less than a certain rating out of the box. So, if a 200 Watt solar panel has a negative tolerance rating of 10% then their 200 watt panel is guaranteed not to have a power rating of less than 180 Watts right out of the box.
In my opinion 10% or even 8% isn’t really that great when there are other solar panel manufacturers who produce solar panels with a negative tolerance rating of only 5%. Therefore, remember while shopping for a solar system, you may hear solar dealers boast about their solar panel’s high efficiency or higher PTC rating or better performance in hot weather. Always ask what there panel’s negative tolerance rating is and if theirs isn’t less than 8%, consider another panel manufacturer.

PTC rating of solar modules

Here’s a Smart Tip! When shopping for a solar electric system, always insist on seeing the solar panel’s specification sheet and look for the minimum warranted power rating so you can accurately determine the power that panel is guaranteed to produce on an optimal day of sunshine.
