Solar Modules

Photovoltaic solar cells use solar power cells to convert light from the sun straight into electricity. At Inventive Solar Solutions, we carry and stock most of the major brands, including Pointed Solar, Kyocera Solar, BP Solar, Evergreen Solar, Solar World, Kaneka, Uni-Solar, Suntech, Sanyo, Day4 and OEM Solar modules.

The three most common types of solar modules are Mono crystalline, Polycrystalline, and Amorphous :

Mono crystal solar modules - made from a single huge crystal, cut from rods. It is the most productive but also the most expensive. It is kind of better in low light scenarios.

Polycrystalline solar modules - cast blocks of silicon which may contain many tiny crystals is the commonest type at this time. Slightly less efficient than single crystal, but once set into a frame with 35 or so other cells, the actual difference in watts per square foot isn't much.

Amorphous solar modules ( also called thin film ) - the silicon is spread at once on giant plates or flexible laminates. They are cheaper to provide, but regularly a lot less efficient, meaning larger panels for the same power. Uni-Solar is one example. The diversities between the 2 solar modules - crystal-like and amorphous- really show up in their sunlight-to-electricity conversion efficiencies and power densities. Crystal-like modules need less space than thin-film modules for the same quantity of powerthin-film is less efficient in the conversion of sunlight to electricity.

Single- and multi crystal-like solar modules have characteristic conversion efficiencies between 12% and 17%. But thin-film technologies can have half that, from 6% to 8%. Thin film modules take up about twice as much space to generate an equivalent quantity of energy compared to crystal-like modules.

Besides power density, there are two key differences in performance between solar modules crystal-like and thin-film technologies. The first is impact of cell temperature on power production. The 2nd is 1st module power stabilizing.

All PV solar modules experience a decrease in power with a rise in cell temperature. For instance, at 100F, our sample crystal-like module will produce approximately 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 allowing acceptable air circulation around any module, PV cells sitting out in the sunshine will still get hotso thin-film a-Si modules could be a sensible choice for warm climates, especially if there's a load of room for the larger array.

Amorphous silicon solar modules take six to twelve months to reach their stable, rated output, while crystal modules stabilize right away. So a-Si solar modules will show twenty p.c. to 25% higher-than-rated production initially. While that sounds like a bonus, this 1st additional output must be considered in system design ( for selecting wire sizes, charge controllers, and inverters ). As an example, if the final design signals a fifteen A circuit, the original extra output might need accommodating twenty A. After this stabilising, thin-film solar modules degrade at similar rates to crystalline, about 0.5% to 1.0% per year.
