Grid-Tied & Off-Grid Applications

Four Elements Energy represents a wide variety of Solar PV Panels and System Components to provide you with the best renewable energy system fit for your budget and site.

Crystalline Solor Photovoltaic

CRYSTALLINE SOLAR PHOTOVOLTAIC

PV panels continue to be the most widespread, cost-competitive solar technology currently available. These panels have a uniform black appearance and are made of silicon wafers mounted on aluminum frames. The electricity that they produce is D/C voltage which is ready to store in batteries or to be used by the renewable energy system components . They are reliable for about 40 years. They are more efficient in terms of space-use than thin-film solar panels. Advocates insist that if PV panels are installed correctly, they can offer payback periods over five years.

Thin-Film Solar Photovoltaic

SOLAR THIN-FILM PHOTOVOLTAIC

Thin-film is a relatively new solar technology, but many observers believe it represents the future of solar energy and some expect the sector to grow to account for a third of all PV production by 2012. A wide range of different thin-film technologies are now available, ranging from more traditional silicon and glass based systems to cutting-edge copper indium gallium selenide cells. What all thin-film cells tend to have in common is that they are particularly efficient at converting INDIRECT light- this is the technology used in solar-powered calculators- and so are therefore suitable for locations that have a higher chance of cloud cover.
