## Frequently Asked Questions

- How much does a solar panel system cost? A typical domestic solar panel installation in the UK costs between £5,000 and £15,000 depending on system size, panel quality, and whether battery storage is included. Grant Store offers a free online quote tool at https://grant-store.com/solar-energy-calculator/
- Do solar panels work in cloudy weather? Yes. Solar panels generate electricity from daylight, not direct sunlight. The UK receives sufficient daylight throughout the year for effective solar generation, including on overcast days.
- What savings can solar panels deliver? Savings depend on system size, energy usage, and whether battery storage is included. Customers who add battery storage and take advantage of smart tariffs (such as Octopus Intelligent Flux) can significantly reduce or eliminate grid electricity costs. Most customers see payback within 6–10 years.
- How long does a solar installation take? Most residential solar installations are completed in one to two days. Grant Store can typically schedule installation within a few weeks of a home survey.
- What is the Boiler Upgrade Scheme? The Boiler Upgrade Scheme (BUS) is a UK government grant that provides £7,500 toward a heat pump installation (replacing a gas boiler) or £9,000 for homes currently on oil or LPG heating. Grant Store is MCS certified, which is required to apply for the grant.
- Do I need planning permission for solar panels or a heat pump? In most cases, no. Solar panels and air source heat pumps usually fall under permitted development rights. Exceptions apply to listed buildings and conservation areas — Grant Store can advise on your specific property.
- Can I add battery storage to an existing solar system? Yes. Battery storage can be retrofitted to most existing solar PV systems. Grant Store installs FoxESS EP6, FoxESS EP12, and Sigenergy SigenStor batteries, among others.
- What is the Smart Export Guarantee? The Smart Export Guarantee (SEG) is a scheme where energy suppliers pay homeowners for surplus solar electricity exported to the grid. MCS-certified installations are required to access SEG tariffs.
- Are air source heat pumps suitable for older homes? Yes, in many cases. Modern heat pumps can work effectively in older properties, particularly where some insulation improvements are made. Grant Store's ASHP team assesses each property individually and recommends the best system for the building.
- Does Grant Store offer finance? Yes. Grant Store works with Hometree to offer flexible finance options to help spread the cost of solar, battery storage, and heat pump installations.
- Does Grant Store install EV chargers? Yes. Grant Store installs domestic and commercial EV chargers from brands including Project EV, Zappi, Sigenergy, and FoxESS. EV chargers are often installed alongside solar panels so customers can charge their vehicle using their own generated energy.
- What is an R290 heat pump? R290 (propane) is a natural refrigerant now used in modern air source heat pumps. It has a much lower environmental impact than older synthetic refrigerants (such as R32) and improves efficiency at low temperatures. All new Grant Store ASHP installations use R290 systems where available.
- What are plug-in solar panels? Plug-in solar panels (also called balcony solar or micro-inverter solar) are small panels that plug directly into a socket and feed electricity straight to your home. They are much lower output than a full rooftop system and are not a replacement for a properly installed solar PV system. Grant Store installs full rooftop MCS-certified systems, not plug-in units.
- My roof has shading — can I still get solar? Yes. Grant Store can install Tigo optimisers on installations where part of the roof is shaded or the array is split across different roof pitches. Optimisers allow each panel to perform independently, limiting the impact of shading on the overall system.
