Solar Panels in Kendal, Cumbria

A 4kWp system in Kendal typically costs £6,600-£8,500 with 0% VAT included, the zero-rate VAT alone saves around £1,300-£1,700 compared to the standard 20% rate. Based on Kendal's solar yield of 848 kWh/kWp, a 4kWp system generates approximately 3,392 kWh/year, paying for itself in 11-13 years through electricity savings of £604+/yr and Smart Export Guarantee income of around 13-15p/kWh. Adding a home battery (5-10 kWh) costs an additional £3,000-£6,500 and also benefits from 0% VAT. We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.

Most homes in Kendal benefit from a 3-6 kWp system. A 4kWp system (10 panels at ~400W each) generates 3,392 kWh/yr at Kendal's yield of 848 kWh/kWp, covering 89% of average household electricity use. The system requires approximately 18-20 m² of unshaded roof space. If you have an electric vehicle or heat pump, a larger 5-6 kWp system (12-15 panels) may be more appropriate to offset the additional demand. Your MCS-certified installer will assess your roof space, orientation, shading, and electricity consumption to recommend the optimal size during a site survey.

Get at least 3 quotes from MCS-certified installers to compare pricing, equipment brands, and warranty terms. Check each company is registered with MCS at mcscertified.com, this certification is required for Smart Export Guarantee eligibility. Look for 25-year panel performance warranties and 10-15-year inverter warranties as a minimum. Ensure your installer includes the DNO notification (G98/G99 application) and handles all paperwork. Remember that 0% VAT applies automatically to residential installations, so you should not be charged any VAT on the total cost.

Most roofs are suitable for solar panels. You need at least 18-20 m² of unshaded roof space for a typical 4kWp system (10 panels at ~400W each). South-facing roofs at 30-40° produce the best yield, but east and west-facing roofs still achieve 80-85% of optimal output. Your MCS-certified installer will assess your roof's orientation, pitch angle, shading from trees or buildings, and structural suitability during a site survey. Slate, tile, and metal roofs are all suitable, though flat roofs require angled mounting frames which add slightly to the cost.

With a cost of £6,600-£8,500 (0% VAT included) and savings of £604+ per year based on Kendal's solar yield of 848 kWh/kWp at current electricity rates of around 25p/kWh, plus Smart Export Guarantee income of around 13-15p/kWh for surplus electricity, a typical solar system in Kendal pays for itself in 11-13 years. Cumbria ranks #65 of 102 UK counties, and solar still pays off here thanks to longer summer daylight hours and cooler temperatures that help panels run more efficiently. After payback, you benefit from 12-19 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-£18,000 depending on your usage pattern.

South-facing roofs at a 30-40° pitch produce the most electricity (100% of potential yield). South-east and south-west roofs produce around 95% of optimal output. East or west-facing roofs still produce 80-85%, and many installers recommend splitting panels across east and west faces to spread generation throughout the day, which can improve self-consumption. North-facing roofs are generally not recommended for solar panels in the UK as they receive significantly less direct sunlight. Your MCS-certified installer will assess your roof orientation during the site survey.

Solar PV panels generate electricity from sunlight using photovoltaic cells, while solar thermal panels heat water directly using the sun's warmth. For most UK homes, solar PV is the better investment: it is more versatile (powering all electrical appliances), benefits from 0% VAT, and you can sell excess electricity via the Smart Export Guarantee at around 13-15p/kWh. Solar thermal only heats water and does not generate electricity or qualify for SEG income. Solar PV panels also last longer (25-30 years versus 15-20 for solar thermal) and have lower maintenance requirements.
