Solar PV Guides

A typical 4kW residential solar panel system in the North East costs between £5,000 and £7,000 including installation and VAT at 0%. Larger systems of 6-8kW range from £7,000 to £10,000. Prices vary depending on panel brand, roof complexity and whether you add battery storage. ALPS Electrical provides free, no-obligation quotes with a full breakdown of costs and projected savings.

Most UK homes need between 8 and 16 solar panels depending on electricity usage, roof size and orientation. A typical 3-bedroom semi-detached house uses around 3,500kWh per year, which can be met by a 4kW system (8-10 panels). Larger detached properties with electric vehicles or heat pumps may need 6-10kW systems (14-24 panels). We conduct a detailed survey to recommend the optimal system size for your specific needs.

Yes, solar panels work effectively in the North East. While the region receives less sunshine than the south of England, modern high-efficiency panels like the Jinko Tiger Neo and JA Solar panels we install generate significant electricity even on overcast days. The North East receives approximately 1,100-1,200 kWh/m² of solar irradiance annually. Winter output is lower but panels still generate electricity — pairing with battery storage ensures you maximise every unit generated.

A standard residential solar panel installation typically takes 1-2 days. If you are adding battery storage, this may extend to 2-3 days. Commercial installations can take 1-2 weeks depending on system size. The full process from survey to switch-on usually takes 4-8 weeks, including the DNO notification or G99 application if required.

Most domestic solar panel installations fall under Permitted Development and do not require planning permission. However, you will need to apply if your property is listed, in a conservation area, or if panels will protrude more than 200mm from the roof surface. Ground-mounted arrays over 9m² also require permission. ALPS Electrical handles all planning considerations and will advise you during the survey.

The typical payback period for solar panels in the UK is 6-9 years based on current electricity prices. With battery storage enabling you to use more of your own generated electricity, payback can be faster. After the payback period, you enjoy free electricity for the remaining 20+ years of the panel warranty. Factors affecting payback include system size, electricity usage patterns, export tariff rates and whether you have an EV or heat pump.
