FAQs

Do solar panels work in the winter or on cloudy days?2026-05-28T18:57:41+01:00

Solar panels generate electricity from daylight and do not need direct sunlight. While production is higher in summer, they continue to generate clean energy throughout the winter and on overcast days.

What is the Smart Export Guarantee (SEG)?2026-05-28T18:57:41+01:00

The SEG is a government-backed initiative. It allows you to earn money by selling any surplus renewable electricity you generate but don’t use back to the national grid.

Will solar panels increase the value of my property?2026-05-28T18:57:41+01:00

Can I use solar power during a power outage?2026-05-28T18:57:41+01:00

Can you help with the paperwork and grid permissions?2026-05-28T18:57:41+01:00

Yes. As part of our service, we manage all necessary DNO (Distribution Network Operator) consultations and applications. This means that your system is safe and legally connected to the grid.

How much can I really save on my electricity bills?2026-05-28T18:57:41+01:00

While every property is different, a bespoke solar PV system can potentially reduce your electricity bills by up to 70 per cent. The exact savings will depend on your energy generation and specific usage patterns.

Does South Thames Solar provide maintenance for systems they didn’t install?2026-05-28T18:57:41+01:00

What is the difference between a grid-tied and a hybrid system?2026-05-28T18:57:41+01:00

A standard grid-tied system converts solar energy for immediate use and sends excess to the grid. A hybrid system includes integrated battery storage, allowing you to capture that surplus energy for use at night or during peak times.

What is an ‘in-roof’ solar system?2026-05-28T18:57:41+01:00

An in-roof system is designed for a sleek, seamless aesthetic, with the panels sitting flush with your tiles. They are applied directly to the roof battens using specialised trays and flashing kits.
Can I add a battery to my existing solar setup?
Yes, we offer battery storage retrofits for existing systems. This allows you to maximise your self-consumption and reduce waste even if we didn’t perform the original installation.

How do I know if my roof is suitable for solar panels?2026-05-28T18:57:41+01:00
