Photovoltaic solar cells use photovoltaic power cells to convert light from the sun directly into electricity. At Leading edge Solar Solutions, we carry and stock most of the top brands, including Sharp Solar, Kyocera Solar, BP Solar, Evergreen Solar, Solar World, Kaneka, Uni-Solar, Suntech, Sanyo, Day4 and OEM Solar modules.
The 3 commonest sorts of solar modules are Mono crystal-like, Polycrystalline, and Amorphous :
Mono crystal-like solar modules - made of a single large crystal, cut from rods. It is the most efficient but also the most costly. It is somewhat better in dim lighting conditions.
Polycrystalline solar modules - cast blocks of silicon that might contain many tiny crystals is the commonest type at the moment. A touch less efficient than single crystal, but once set into a frame with 35 or so other cells, the particular difference in watts per square foot is not much. Amorphous solar modules ( also called thin film ) - the silicon is spread immediately on large plates or flexible laminates. They are cheaper to provide, but often much less efficient, that means larger panels for a similar power. Uni-Solar is one example. The differences between the 2 solar modules - crystal and amorphous- really show up in their sunlight-to-electricity conversion efficiencies and power densities. Crystal-like modules require less space than thin-film modules for the same amount of powerthin-film is less efficient in the conversion of sunlight to electricity.
Single- and multi crystal solar modules have typical conversion efficiencies between 12% and 17%. But thin-film technologies can have half that, starting from 6% to 8%. Thin film modules take up about 2x as much space to generate an equivalent amount of energy matched against crystalline modules.
Besides power density, there are 2 major differences in performance between solar modules crystal and thin-film technologies. The 1st is impact of cell temperature on power production. The second is first module power stabilizing.
All PV solar modules experience a decrease in power with increasing cell temperature. As an example, at 100F, our sample crystal-like module will produce roughly 6% less power than its STC rating. This effect is less expounded for thin-film PV technologiesour example a-Si thin-film module would produce only two percent less power. While you can reduce cell temperature by permitting acceptable air circulation around any module, PV cells sitting out in the sunshine will still get hotso thin-film a-Si modules might be a sensible choice for warm climates, especially if there is plenty of room for the larger array.
Amorphous silicon solar modules take six to 12 months to reach their stable, rated output, whereas crystal-like modules stabilise right away. So a-Si solar modules will show 20% to twenty five percent higher-than-rated production at first. While that sounds just like a bonus, this initial extra output must be considered in system design ( for selecting wire sizes, charge controllers, and inverters ). For instance, if the final design denotes a fifteen A circuit, the original extra output might need accommodating 20 A. After this stabilization, thin-film solar modules degrade at similar rates to crystal-like, about 0.5% to 1.0% each year.
