Solar energy is one of the most powerful ways to cut your bills and your carbon footprint simultaneously. Here's everything you need to know before you invest.
South-facing roofs at a 30–40° pitch maximise generation, but east- and west-facing panels still deliver 80–85% of the potential output. Modern microinverters mean partial shading from a chimney or tree no longer wipes out your entire array — each panel operates independently. Most installations qualify for 0% VAT, and the Smart Export Guarantee (SEG) means your supplier must pay for every unit you export. 1ENERGY's free solar calculator gives you a personalised estimate in under a minute.
It's free, takes 90 seconds, and could save you hundreds every year. No account needed.
