How much can solar panels reduce my electricity bills?

Solar panels can reduce your electricity bills by generating free power during daylight hours. The exact savings depend on system size, roof orientation, shading, your electricity usage pattern (especially daytime use), and current energy tariffs. Many households see meaningful reductions, and adding a battery can increase the proportion of solar energy used at home. For an accurate estimate, request a tailored solar quote based on your roof and usage.

Do I need a south-facing roof for solar to work well?

A south-facing roof is often ideal, but solar can still perform well on east- or west-facing roofs and even on some other orientations depending on shading and roof pitch. East/west systems can be a great fit for households that use electricity in the morning and evening. A site survey can confirm the best layout and expected output.

How long do solar panels last and what warranties are typical?

Solar panels are designed to last for decades. Many manufacturers provide long performance warranties (often around 25 years) and product warranties that vary by brand. Inverters and batteries typically have shorter warranty periods than panels. Your proposal should clearly set out the warranties for panels, inverter, battery (if included), and workmanship.

Can I add a solar battery now or later?

Yes. Many systems can be designed to be battery-ready, allowing you to add storage later. Adding a battery can increase self-consumption by storing daytime solar for evening use and may provide backup features on compatible setups. The best option depends on your goals, budget, and existing inverter type.

Do solar panels work in winter or on cloudy days in the UK?

Yes. Solar panels generate electricity from daylight, so they still work on cloudy days and through winter—though output is lower compared with summer due to shorter days and lower sun angle. Annual generation estimates account for seasonal variation, which is why a full-year projection is recommended.

Will I be paid for exporting solar electricity to the grid?

In the UK, many households can earn money by exporting surplus electricity through an export tariff (often referred to as SEG—Smart Export Guarantee) with eligible meters and suppliers. Eligibility and rates vary by supplier and setup. Your installer can advise on system compliance and what you need to access export payments.

Do I need planning permission for solar panels?

Most domestic solar installations in the UK fall under permitted development, meaning planning permission is not usually required. Exceptions can apply for listed buildings, conservation areas, or if panels are installed in certain prominent positions. A survey will confirm any constraints before installation.

How long does a solar panel installation take?

Many residential solar installs are completed in 1–2 days, depending on system size, roof type, and whether a battery is included. The process typically includes a survey, system design, installation, commissioning, and handover with guidance on monitoring and maintenance.
