How does the recommendation and savings tool know the best kit size?

Taking the below information the tool will determine how many solar panels your roof can fit and recommend the biggest size available. 

What it looks at: 

• Electricity Rates/Tariff: Rate/Tariff you are currently on from the electricity bill you upload 

• Enlectricity retailer: if you don’t have your electricity bill available, the system will use the popular plans available from the retailer you enter 

• Electricity Use: Taken from your electricity bill and Market Settlement and Transfer System (MSATS), this provides the average daily use of your home.  

• Home set-up: The big energy using items in your home: EVs and Pools 

• Roof information: Shading (e.g. tree overhang), roof and eaves height, roof material (e.g. tiled), roof shape, roof pitch, roof north facing size – taken from publicly available information
