Installed over December and January 2015/2016 this 526 panel, 150kWp system generating 140,000kWh/year has been one of the most impressive installs for UK Solar Generation to date. Over the year the huge bills have been reduced by nearly 20% which even without the Feed-in Tariff would offer a saving of 12p kW/h x 117mWh = £14,000. The system was installed for £125,000.
