Along with their solar panels, a typical household would purchase a JA Solar kit, which includes microinverters, monitoring equipment, accessories and racking (depending on the configuration and size of the roof).

Based on our research, you can expect to pay between £85 and £150 per JA Solar solar panel. However, the exact price will depend on the specific model of solar panel you choose and the installer you go for.
Typically, you’ll buy a solar panel system rather than individual panels, so it’s best to get a comprehensive quote, including installation costs, from a solar panel installer. To reduce the overall cost, you should also investigate whether you could benefit from a solar panel grant or buying scheme.
You don’t need to do any maintenance on JA Solar panels, and the company fully guarantees its product for 12 years. You can claim on the performance warranty if performance drops below the expected range at any given point in the panel’s first 30 years – for example, below 98 per cent in year 1.
If the panels become very soiled, you can clean them with a soft sponge and water, but you shouldn’t use chemical cleaners. Instead of climbing on the roof to clean panels manually, you should hose the solar panels down from the ground. It’s worth noting that cleaning should always be done when the panels are at their coolest (in the early morning or evening).
According to our survey, 44% of JA Solar customers found that the maintenance requirements for their panels “exceeded expectations”, meaning they required less upkeep than they had anticipated. However, only 34% of customers found that their JA Solar panels exceeded their expectations for energy production.
Overall, 46 per cent of the JA Solar customers we surveyed would “very much recommend” their panels, while 53 per cent would “somewhat recommend” them.
The JA Solar’s high power output of 530W means you’ll need fewer panels, and with a relatively low price per panel, it could be an option if you want to get solar on a budget.
However, this panel also has the highest annual degradation rate, the shortest warranties and a middling efficiency rating compared with other solar panels we’ve reviewed.
