J A Solar
The JA Solar range of panels offer a good range of wattage for your pound, they are made to a good standard, which we feel gives a good return on your investment. They are good to look at and offer a product from a company that has been in the UK for many years, whom we feel will give long term support and warranty should it be required. The wattage of panels is always changing, so we may quote for a different panel than the data sheets shown here below.
JA Solar JAM60S
Sanyo
The Sanyo HIT Range of Panels are a very good overall performer, however these are probably one of the more expensive products on the market at present. We supply these if the customer requires them, but they will affect your payback time due to costs. These are however smaller in size than many other manufacturers, and therefore on some size specific installations these could be beneficial. These panels have some of the best Kw returns of any panel on the market.
