Solar Panels in Fulham, Greater London

A 3-4kWp system in Fulham typically costs £5,000-£8,000 with 0% VAT included — the zero-rate VAT alone saves around £1,000 compared to the standard 20% rate. Based on Fulham's solar yield of 960 kWh/kWp, a 4kWp system generates approximately 3,840 kWh/year, paying for itself in 6-8 years through electricity savings of £1075+/yr and Smart Export Guarantee income of 4-6p/kWh. Adding a home battery (5-10 kWh) costs an additional £3,000-£6,000 and also benefits from 0% VAT. We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.

Standard grid-tied solar systems shut down automatically during a power cut for safety reasons — this is to protect engineers working on the grid lines. Your panels will resume generating as soon as the grid power is restored. If you need backup power during outages, you can install a hybrid inverter with battery storage that isolates your home from the grid and continues supplying electricity from the battery and panels. This emergency power supply (EPS) feature is available on most modern hybrid inverters and is worth considering if you experience frequent power interruptions.

Solar panels stay with the property as a permanent fixture and transfer to the new owner upon sale. They add value to your home — up to 4% according to UK property research — and improve the EPC rating, making the property more attractive to energy-conscious buyers. Your installer can transfer monitoring app accounts and warranty documentation to the new owner. The Smart Export Guarantee registration also transfers with the property. With a 25-30 year lifespan, the next owner inherits many years of remaining electricity savings.

With a cost of £5,000-£8,000 (0% VAT included) and savings of £1075+ per year based on Fulham's solar yield of 960 kWh/kWp at current electricity rates of 28p/kWh, plus Smart Export Guarantee income of 4-6p/kWh for surplus electricity, a typical solar system in Fulham pays for itself in 6-8 years. Greater London ranks #17 of 102 UK counties for solar yield — above the national average. After payback, you benefit from 17-22 years of near-free electricity as panels last 25-30 years. Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£25,000 depending on your usage pattern.

Solar panels need very little maintenance over their 25-30 year lifespan. UK rainfall keeps them clean in most cases, and there are no moving parts to wear out. Your inverter may need replacing once during the system's lifetime (10-15 year lifespan, costing around £500-£1,000). An annual visual check to ensure no debris, bird nesting, or damage is recommended, along with occasional cleaning if panels are near trees or at a low pitch angle. Some installers offer maintenance packages, but these are generally optional rather than essential.

An Energy Performance Certificate (EPC) rates your home's energy efficiency from A (most efficient) to G (least efficient). While an EPC is not required for solar panel installation, adding solar panels typically improves your rating by 1-2 grades, which can increase your property value by up to 4%. An EPC assessment costs around £60-£120 and is valid for 10 years. If you are selling or renting your property, an up-to-date EPC is legally required, so having solar panels reflected in your rating is beneficial.

Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof, making them well worth installing. Many installers recommend splitting panels across east and west faces to spread generation throughout the day, which can improve self-consumption and reduce the amount of electricity exported at the lower SEG rate. East-facing panels generate more in the morning, while west-facing panels peak in the afternoon — both align well with typical household usage patterns. Only north-facing roofs are generally unsuitable for solar in the UK.
