Solar PV & Battery Savings Calculator for Daventry

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

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 Daventry?

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 Daventry. Competitive export tariffs pay between 5p and 15p+ per kWh.

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

Yes. With domestic electricity tariffs around 7.5p/kWh in Daventry, direct self-consumption generates substantial savings. Because capital expenditure is lower, standalone solar systems often achieve a payback period of 6 to 8 years.
