An unusual roof and a steep pitch meant that this 6kW south-facing install was a little different to the norm, but the result is a system that produces tons of power even on a sunny December day. In fact the low winter sun hits these panels at just the right angle, so even in the depths of winter it’s capable of generating several kilowatts of power and enough to fill a 5kWh battery whilst also powering the house. You could say it’s a literal ‘powerhouse’…ahem.
