How efficient are JA Solar panels?

However, when combined with N-type technology, JA’s monocrystalline solar cells are at the top of the efficiency scale for mid-range solar panels. A solar panel efficiency rating of more than 20 percent is considered very good.

Can JA Solar modules be installed on a roof?

JA solar modules have been listed as Class A according to IEC 61730-2 standard. For roof installations, modules should be mounted over a fire resistant covering suitable for this application, with adequate ventilation between the modules backsheet and the mounting surface. Roof constructions and installations may affect the fire safety of building.

How much power does a JA Solar panel produce?

Power output of most home solar panels in the UK is 250W to 400W. JA solar panels are either at the higher end of this range or exceed it. For example, JAM60S20/MR solar panels offer 21 per cent efficiency with a peak power output of 390W, at a lower price than similar solar panels from many other manufacturers.

Do JA Solar panels have a warranty?

This results in lower prices for customers. JA solar panels typically come with a 12-year product replacement warranty and a 25-year power output warranty. The 12-year equipment warranty is shorter than that offered by some solar panel manufacturers. But the product warranty is in line with industry standards.
