Solar Panel FAQs

Yes. Solar PV panels generate electricity from daylight, so they still work when it is cloudy. Output changes with light levels and is generally higher in stronger sunlight.

No. A south-facing, unshaded roof is ideal for maximum annual generation, but east- and west-facing roofs can also be suitable. Energy Saving Trust says east- or west-facing systems tend to generate around 15-20% less than a directly south-facing equivalent.

Yes, subject to structural and design considerations. Panels are normally mounted at an angle and the system must account for loading, wind and waterproofing.

Potentially, yes. The structure needs to be suitable and the electrical connection back to the property needs to be considered.

Yes. Ground-mounted solar can be an option where suitable land is available. Orientation, shading, cable routes, planning and visual impact all need to be assessed.

It depends on the panel and system size. As a benchmark, Energy Saving Trust says an average 4.5kWp system typically uses around 12 panels and 20-30m² of roof area.

There is no single reliable percentage for every home. Savings depend on generation, self-consumption, electricity prices, battery use and export tariff. GS Solar provides a tailored estimate as part of the proposal.

Eligible customers can potentially receive payment for exported electricity through the Smart Export Guarantee or another available export tariff. Rates and terms vary by supplier and eligibility requirements apply.

No. Solar works without a battery. A battery can help store surplus generation for later, but whether it is worthwhile depends on your electricity use and goals.

Often this can be explored, but compatibility depends on the existing system. GS Solar can assess the equipment and advise on suitable options.

Yes. They generate from daylight throughout the year, but winter generation is generally lower because days are shorter and light levels are lower.

No. Solar panels do not generate from sunlight at night. The property uses battery power if available and configured, or imports electricity from the grid.

Solar PV generally requires relatively little routine maintenance because the panels have no moving parts. System performance should still be monitored and faults or damage addressed when needed.

The installation time depends on the system and property. GS Solar will confirm the expected timescale for your project before installation rather than giving a misleading one-size-fits-all promise.

Domestic solar panels are often permitted development, but exceptions apply, including some listed buildings, conservation areas and other sensitive locations. Check the specific property and local planning requirements.

The inverter converts the direct-current electricity generated by the solar panels into alternating-current electricity that your home or business can use.

MCS is a recognised quality mark for small-scale renewable energy products and installations. It sets standards for certified installers and installations.

RECC members agree to follow a consumer code covering standards before, during and after the sale and installation of small-scale renewable energy systems.

Yes. GS Solar offers upgrades and replacement panels for existing systems, subject to assessment of the current installation.

The price varies too much by property and specification for GS Solar to publish a meaningful fixed package price. System size, access, roof type, battery storage, integration and other factors affect the quote. GS Solar provides a tailored quotation after assessment.
