Solar questions

Do I need planning permission?

Usually not for a house. Listed buildings and conservation areas may need it. Check with your council.

What is the SEG?

The Smart Export Guarantee (SEG) pays you for power you send back to the grid. Rates vary by supplier.

Why might my real saving differ?

Shading, your usage pattern and your tariff all change it. An installer survey gives the final figure.
