What is JA Solar?

JA Solar focuses on production of powerful monocrystalline solar photovoltaic (PV) cells with PERC (Passivated Emitter and Rear Cell) technology. Consisting of high-purity, half-cut single silicon crystals, these solar cells are far more efficient than cheaper polycrystalline solar panels, which need more roof space.

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.

Which JA Solar panel is best?

JA Solar’s JAM60S20 panel offers high efficiency of 21 per cent and a power output of 340W, for a lower price tag than many of its competitors. Meanwhile, the JAM72S30 LR solar panel stands out for larger homes, as it boasts an impressive power output of 585W, which is a greater output than most domestic panels.

Are JA Solar panels better than other solar companies?

On the downside, JA solar panels are less powerful than those produced by some larger solar companies, which may also offer longer warranties. JA Solar focuses on production of powerful monocrystalline solar photovoltaic (PV) cells with PERC (Passivated Emitter and Rear Cell) technology.

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.

How reliable is JA Solar?

Since 2017, JA Solar has consistently scored in the ‘Top performer’ category of the DNV GL/PVEL PV Module Reliability Scorecard report. DNV GL is a leading authority of independent energy experts, and PVEL conducts independent PV testing. This annual report identifies 20 high-performing solar panel manufacturers.
