Our Common Solar FAQs
The installation process itself usually takes only one to three days and is completed by a highly skilled team of in-house installers.
The more solar panels you have installed, the more energy they’ll be able to generate for your home. The number of solar panels you’ll need will depend on your energy usage, the number of people in your home and the size of your property. Smaller homes might need a 1kW system, with roof space for 8+ square metres of solar panels, while higher demand can be met with a 4kW system, but that would need 25+ square metres of space on your roof.
You can charge your electric vehicle (EV) with solar panels if you have the right setup. You’ll need a solar PV system and a solar-compatible EV charger, and a solar battery storage system if you want to charge overnight. While there’s an upfront cost to install this equipment, you’ll save money on charging in the long run. Solar charging is a sustainable option, and you’ll avoid the fuel costs associated with traditional gasoline cars.
- A 3–4 kW system for a typical family home falls within this range.
- Adding battery storage can increase costs by £3,000–£5,000 but improves long-term savings.
- With the 0% VAT on solar installations, you can reduce upfront costs further.
- Smaller households may only need 8–10 panels.
- Larger homes or those with EV chargers and heat pumps may require 16–20.
- Each modern panel produces around 350–400 watts of electricity.
- Most panels come with 25-year performance warranties.
- Inverters may need replacing after 10–15 years.
- Minimal maintenance is required beyond occasional cleaning.
- Scotland receives 1,000–1,200 hours of sunshine annually, which is sufficient for solar.
- Modern panels are highly efficient at capturing diffuse light.
- Cooler temperatures actually improve panel efficiency.
- On sunny days, panels perform at peak capacity.
- On overcast days, they continue contributing to your household’s energy needs.
- Adding battery storage allows you to use solar power at night.
- Rain naturally helps keep panels clean, but professional cleaning may be needed every few years if dust or debris builds up.
- Annual inspections can help identify issues early, such as inverter wear or wiring checks.
- Panels are durable and built to withstand harsh Scottish weather.
- A 4 kW system can offset around 40–50% of a home’s electricity demand.
- With rising energy costs, savings are likely to grow over time.
- Excess electricity can often be sold back to the grid through export tariffs.
- The Smart Export Guarantee (SEG) allows you to earn money by exporting unused electricity back to the grid.
- Local councils sometimes offer funding or support schemes.
- Certain financing options, like Home Energy Scotland loans, may also be available.
- Smaller systems may be completed in a single day.
- Larger systems with battery storage may take longer.
- Installation involves mounting panels, wiring the inverter, and connecting the system to your home.
- Exceptions may apply for listed buildings or properties in conservation areas.
- Panels should not protrude more than 200 mm from the roof surface.
- Ground-mounted panels may require approval depending on size.
- Solar-equipped homes often sell faster than similar homes without them.
- Energy savings and sustainability are appealing to modern buyers.
- Panels with warranties and recent installation dates are especially attractive.
- Monocrystalline panels are the most efficient option.
- Scotland’s cooler climate helps panels perform at their best.
- Panel efficiency continues to improve with new technology.
- High-usage homes may still need some grid electricity.
- Battery storage allows full use of solar power, even at night.
- Larger systems can cover EV charging and heat pumps.
- Panels convert sunlight into electricity.
- Batteries capture excess power to use at night or during outages.
- Batteries increase savings and energy independence.
- Households with high energy use or battery storage may recover costs faster.
- Rising energy prices shorten payback times.
- After payback, all electricity generated is essentially free.
- Heat pumps benefit from cheap, renewable electricity.
- EV chargers can be powered during the day or via stored energy in batteries.
- Combining technologies maximises savings and reduces carbon footprints.
- Roof surveys are carried out before installation.
- Some listed buildings may need planning permission.
- Ground-mounted systems are an alternative for unsuitable roofs.
- Warranties cover both performance and product quality.
- Some premium brands offer extended cover.
- Batteries also come with separate warranties.
- Roofs in good condition with minimal shading are best.
- Structural strength is assessed before installation.
- Alternatives include ground-mounted systems.
- Monthly payments spread the cost over time.
- Savings on bills can help offset finance costs.
- Options vary depending on provider.
- Inverters may emit a faint hum but are usually installed in lofts or utility rooms.
- Maintenance is also quiet and unobtrusive.
- A typical system saves 1–2 tonnes of CO₂ per year.
- Over 25 years, that’s 30–50 tonnes of avoided emissions.
- Solar helps the UK move towards net-zero targets.
- Check for MCS certification, which ensures quality standards.
- Look for local installers with proven track records.
- Ask about warranties, aftercare, and support.
