The client wanted to reduce carbon emissions and have cheaper electricity bills.
EnergyMyWay recommend the installation of a 13.5kWp Solar PV panel array, comprising of 54 no 250W Vikram Solar Eldora Ultima 250w modules.
After conducting a third survey we recommend panels across the two pitched roof properties. In order to help counteract the detrimental effect of varied levels, roof pitches and shading we recommend a Solaredge Inverter with Solaredge optimisers. The inclusion of an optimiser will increase the generation of the array as well as providing a valuable online monitoring option that both the owner and I can use to track the daily generation of each and every panel.
