Do solar panels increase property value in Acton?
Yes. Solar panels improve your EPC rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Acton is a long-term investment in your property.
What size solar system do I need for my home in Acton?
Most homes in Acton 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.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
What happens to my solar panels if I move house in Acton?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. Your installer can transfer monitoring accounts to the new owner.
Can I get solar panels on an east or west facing roof in Acton?
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.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
