What is the difference between residential and commercial solar systems? +
Residential solar panels are designed to power homes, typically using smaller PV systems installed on rooftops, while commercial solar systems are larger installations built to meet the higher energy demands of businesses and industrial buildings. Both use the same solar technology, but commercial systems often include higher-capacity inverters and more complex installation planning.
How much do solar panels cost in the UK? +
The average cost of solar panels in the UK varies depending on system size and property type. For a typical 4kW residential system, costs usually range from £5,000 to £7,000, while larger commercial solar installations can start around £15,000 and increase depending on scale and power requirements.
Are solar panels worth it for my home or business? +
Solar energy offers long-term savings on electricity bills and reduces reliance on the grid. For homes, solar panels can cut bills by up to 70% and boost property value. For businesses, commercial solar systems improve sustainability credentials and can deliver strong ROI over time through reduced operational costs and Smart Export Guarantee payments.
How do I compare solar panel quotes effectively? +
When comparing solar panel quotes, look beyond the headline price. Compare the total system cost, the efficiency of PV panels, inverter type, warranty length, and installation quality. Using a trusted solar panel comparison service helps ensure you’re getting competitive quotes from MCS-certified installers.
What is included in a solar installation quote? +
A typical solar installation quote will include PV panel type, inverter model, mounting equipment, battery storage options (if applicable), labour, and warranties. Reputable solar companies also provide estimated annual savings, payback period, and Smart Export Guarantee income projections.
How long does it take to install solar panels? +
Most residential solar panel installations take between one and three days, depending on system size and roof access. Commercial solar projects may take longer due to larger arrays, more extensive wiring, and business-site scheduling, but both are designed to minimise disruption.
Do I need planning permission for solar panels? +
In most cases, solar panels for homes and commercial buildings fall under “permitted development” and do not require planning permission. Exceptions may apply for listed buildings, conservation areas, or roof-mounted systems exceeding certain height or visibility limits.
Can I store solar energy for later use? +
Yes, with a home or commercial battery storage system, you can store excess solar energy generated during the day and use it in the evening or during peak hours. This maximises savings, increases energy independence, and improves resilience during power cuts.
What is the Smart Export Guarantee (SEG)? +
The Smart Export Guarantee allows homeowners and businesses with solar panels to earn money for exporting unused electricity back to the National Grid. Energy suppliers pay you per kilowatt-hour (kWh) of exported energy, helping improve overall solar payback.
Who are the best solar companies in the UK? +
The best solar companies are those that are MCS-certified, offer clear warranties, and provide transparent pricing. Solar Panel Comparison partners only with trusted UK solar installers, ensuring quality workmanship and reliable aftercare for both residential and commercial clients.
How can businesses benefit from commercial solar panels? +
Commercial solar panels help businesses reduce overheads, stabilise energy costs, and meet sustainability targets. They can also provide tax advantages and improve ESG performance, making them a smart long-term investment for commercial buildings and industrial properties.
What factors affect the cost of a commercial solar installation? +
The cost of a commercial solar system depends on the building size, roof type, energy usage, and chosen equipment. While initial costs are higher than residential setups, businesses often enjoy faster ROI through large-scale energy savings and government-backed incentives.
