Solar PV & Battery Savings Calculator for Walthamstow

Q: Are East-West roof configurations worth installing in Walthamstow?

Yes. While East-West arrays produce around 10% to 15% less total annual energy than ideal South-facing roofs, they generate power during early mornings and late afternoons, aligning perfectly with peak morning and evening domestic power demand.

Q: How does the Smart Export Guarantee (SEG) pay in Walthamstow?

The Smart Export Guarantee (SEG) requires electricity suppliers to pay you for every kilowatt-hour of surplus clean electricity exported into the local distribution grid in Walthamstow. Competitive export tariffs pay between 5p and 15p+ per kWh.

Q: Is rooftop solar worth installing in Walthamstow without a battery?
