We were asked to install a flat roof system on this customer’s garden room building. We looked at the differences in generation between having the panels east facing or south facing, considering there was a fair amount of shading from the west. The software we use suggested that the panels would still be better south facing.
The system comprises of:
10 x Jinko all black 435w solar panels
GivEnergy 5kW hybrid inverter
GivEnergy 9.5kWh battery
iBoost
K2 flat roof ballasted mounting system
The customer should see a generation of around 2600kWh per year and should save about £550 in the first year.
