Solar panels contain electrons which move when hit by sunlight. This movement creates an electric current that is channelled into usable electricity. The electricity is then sent out of the solar panel through wires, ready to power lights, gadgets, electric vehicles, or be sent back to the grid, with suppliers paying you for that exported energy. The direct sunlight causes the electrons in the solar cells to become excited and jump from one energy level to another, creating electricity. The more sunlight that hits the panels, the more electricity is produced.

What Are the Benefits of Solar Panels?
The biggest gain comes from using the electricity your panels generate yourself, potentially saving up to £360 a year on bills. You could also get paid up to £370 a year for excess energy sent back to the grid under the Smart Export Guarantee (SEG) scheme, though rates vary widely between suppliers. Overall, solar panels can save money on bills, earn extra cash from exports, reduce your carbon footprint, and make you more self-sufficient in your energy needs. With energy bills skyrocketing, solar panels are becoming an increasingly smart investment for eco-conscious households looking to take control of costs.
What Factors Determine Savings and Payments?
Where you live affects payments, as northern homes get less daylight. Using energy yourself when panels are generating it saves more than exports. Working from home increases savings versus being out all day. The SEG scheme may not last 20+ years, so predicted long-term payments are uncertain. The orientation and tilt of your roof, amount of daylight hours, energy usage habits, and SEG rates offered by suppliers all impact just how much you can save.
How Much Do Solar Panels Cost?
A typical 3.5 kilowatt-peak system costs around £7,000. The break-even point is about 14 years - less if electricity prices rise. Run your details through the Energy Saving Trust's solar panel calculator for a cost estimate. Prices vary on factors like your roof type, panel brand, and whether batteries are included. Get multiple quotes from reputable installers before deciding. Maintenance costs are low, but your inverter may need replacing after 10-15 years for a few hundred pounds.
How Can I Maximise Savings?
Use electricity yourself when panels are generating it. Paying 25p/kWh versus earning ~12p/kWh exporting makes sense. Shift energy use to daylight hours by running appliances and charging electronics when the sun is up. Invest in a solar battery to store surplus energy to use at night. Check if your panels are clean and unshaded regularly to maintain optimal electricity generation.
Is My Home Suitable?
South-facing roofs are best, but east or west can work. Avoid too much shade from trees or buildings. You need adequate roof space - panels take up around two square metres each. Ensure no roof damage that could affect installation. Flat roofs need more equipment to angle panels. Planning permission is usually not needed but check with your council if listed/in a conservation area.
With rising energy bills, solar panels can be a smart investment - speak to a solar panel company for advice tailored to your home. Crunch the numbers yourself as savings depend on many factors. For eco-friendly households playing the long game, panels could pay for themselves within their lifetime if used wisely.
