❓ Solar Panel FAQs – Your Questions Answered
Thinking about installing solar panels but still have questions? You’re not alone. Here are answers to the most common queries UK homeowners ask before going solar.
🌥️ Do Solar Panels Work in Cloudy Weather?
Yes! Solar panels generate electricity from daylight, not just direct sunlight. Even on overcast days, they produce energy — just at a slightly reduced rate. The UK’s climate is well-suited for solar PV, with modern panels designed to perform efficiently in diffused light.
❄️ Do Solar Panels Work in Winter?
Absolutely. While winter days are shorter and less sunny, solar panels still generate electricity. In fact, cooler temperatures can improve panel efficiency. You’ll produce less than in summer, but your system will still contribute to your energy needs year-round.
🧼 What Maintenance Do Solar Panels Need?
Very little. Solar panels have no moving parts and are built to last. Occasional cleaning (especially if you live near trees or in a dusty area) helps maintain performance. Most systems come with a 25-year performance warranty and require minimal upkeep.
🏠 Can I Install Solar Panels on a Flat Roof?
Yes. Flat roofs can be fitted with solar panels using angled mounting systems to optimise sunlight exposure. A site survey will determine the best layout and orientation for maximum efficiency.
🔋 Can I Add Battery Storage Later?
Definitely. Many homeowners start with solar panels and add batteries later. Battery storage lets you store excess energy for use at night or during peak times, increasing your independence from the grid.
⚡ What Happens During a Power Cut?
If you don’t have battery storage, your solar system will automatically shut down during a power cut for safety reasons. With a battery and backup system, you can continue powering essential appliances even when the grid is down.
🏡 Will Solar Panels Increase My Property Value?
Yes. Energy-efficient homes are more attractive to buyers. Solar panels can increase property value and help homes sell faster, especially as energy costs rise and sustainability becomes a priority.
💷 How Much Can I Save with Solar Panels?
Savings vary based on system size, energy usage, and location. Most UK homeowners save between £400–£800 per year on electricity bills. You can also earn money by exporting excess energy through the Smart Export Guarantee (SEG).
📅 How Long Does Installation Take?
Most domestic solar installations take 1–2 days. The process includes scaffolding setup, panel mounting, inverter installation, and system testing. We handle everything — from survey to certification.
