Common Questions About Going Solar in Hammersmith
How much do solar panels cost in Hammersmith?
A 3-4kWp system in Hammersmith typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,840 kWh/year, paying for itself in 6-8 years.
Is my roof suitable for solar panels in Hammersmith?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT.
What size solar system do I need for my home in Hammersmith?
Most homes in Hammersmith benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 101% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How does shading affect solar panels in Hammersmith?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
Can I get solar panels on an east or west facing roof in Hammersmith?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
