Frequently Asked Questions

Solar panels convert sunlight into electricity through photovoltaic cells. When photons from sunlight hit these cells, they knock electrons loose from atoms, generating a flow of electricity. This direct current (DC) is then converted to alternating current (AC) by an inverter for use in your home.

The cost varies significantly based on system size, equipment quality, and your location. In the UK, a typical 4kW residential system costs between £5,000-£8,000 before any incentives. Our assessment provides a personalized cost estimate based on your specific situation.

Most roofs are suitable for solar, but optimal conditions include south-facing orientation (in the northern hemisphere), minimal shading, and adequate structural integrity. Our assessment analyzes satellite imagery and local weather data to determine your roof's solar potential.

Quality solar panels typically last 25-30 years or more. Most manufacturers guarantee at least 80% of original output after 25 years. Inverters usually need replacement every 10-15 years. With minimal maintenance, solar is a long-term investment.

We're an independent advisory service, not solar installers or a lead marketplace. Our assessment is based purely on your home's physics, shade data, and economics—not on selling you a system. We provide unbiased information so you can make the best decision for your situation.

Yes, completely free with no strings attached. We believe everyone deserves access to quality solar information before making a significant investment. There's no obligation to proceed, and we never share your data with installers without your explicit consent.

Our analysis uses LIDAR-based shade modeling, satellite imagery, and local utility rate data to provide engineering-grade estimates. While actual results depend on installation quality and weather variations, our projections are typically within 10% of actual performance.

Your privacy is paramount. We never sell your data or share it with third parties without your explicit permission. You can request deletion of your data at any time. See our Privacy Policy for full details.

A typical residential installation takes 1-3 days once all permits are approved. The entire process from signing a contract to system activation usually takes 4-8 weeks, depending on your utility company and local permitting requirements.

Solar panels are remarkably low-maintenance. Rain typically keeps them clean, though occasional cleaning may be needed in dusty areas. Annual inspections are recommended to check connections and mounting hardware. Most systems include monitoring to alert you to any issues.

Battery storage allows you to store excess solar energy for use at night or during outages. While batteries add cost, they can increase your energy independence and provide backup power. Our assessment can help you evaluate whether battery storage makes financial sense for your situation.
