Renewables
Renewables for lower bills and lower carbon
Understand solar PV, batteries, export income, and wider renewable planning with a cleaner, more practical route from quick estimates to deeper project scoping.
Start with the roof, tariff, and usage pattern
Renewable decisions become clearer when you combine basic site characteristics with realistic self-consumption and export assumptions. This section gives you a simple starting point before detailed installer quotes.
Quick route: model solar savings first
Use the calculator to see whether a likely system size fits your annual bill and roof orientation.
