UK legalizes 800 W plug-in solar kits across Great Britain

New UK rules taking effect Aug. 27 allow consumers in England, Wales and Scotland to buy and self-install plug-in solar arrays up to 800 W without using a certified installer. The government says the kits could cover up to 20% of average household electricity use and save families up to GBP 110 per year, while plug-in batteries remain outside the change pending further safety review.
