REA Solar module costs

REA Solar only markets one solar panel in the UK – its Fusion 2 panel. This is an N-type bifacial module, meaning it can generate energy from both faces of the panel. N-type cells are unaffected by light-induced degradation (LID). 

The Fusion 2 offers an efficiency of 23.9 per cent, a power output of 420W and is priced at £500 per module, making it a premium-priced panel. JA Solar sells a 420W panel delivering an efficiency of 21.5 per cent and priced at £115 each, as does Jinko Tiger, with its module costing £177.
