Are you looking to know How Do Solar Panels Work? then read this article to find out How Do Solar Panels Work
Solar panels convert sunlight into electricity. They contain small particles called electrons, which move when exposed to direct sunlight. solar panels Birmingham generate this movement, creating an electric current that flows through wires and powers devices in your home. Any extra energy can be sent back to the power grid, and you might get paid for it.
Key Points to Know Before Installing Solar Panels
1. Solar Panels Can Save You Money
With rising energy costs, generating solar power can reduce your bills. Under the Smart Export Guarantee (SEG) scheme, households in Great Britain get paid for unused solar energy sent back to the grid. A typical household with a 3.5 kilowatt-peak system can save between £140 and £340 per year, depending on how much energy they use.
2. Earn Money for Extra Energy
The SEG scheme pays you for exporting unused electricity. The rates vary by supplier, ranging from 1p to 40p per kilowatt hour (kWh). On average, you could earn £270 to £400 annually from exported energy.
3. Break-even Timeframe
Installing a 3.5 kilowatt-peak solar panel system costs around £7,000. It takes about 11 to 14 years to recover the installation costs through bill savings and SEG payments. The timeframe depends on your location, electricity usage, and the rates you receive.
Tips to Maximize Savings
- Use electricity during the day: Running appliances like washing machines and dishwashers when the panels generate power reduces your need for grid electricity.
- Avoid exporting too much: Since SEG rates are lower than the cost of buying electricity, it’s better to use the energy yourself.
- Consider a battery: A solar battery stores extra energy for later use, reducing your reliance on grid electricity. However, batteries are costly and can extend the break-even point by 5 to 13 years.
Is Your Home Suitable for Solar Panels?
Not all homes are ideal for solar panels. Consider the following:
- Roof direction: South-facing roofs generate the most energy. East- or west-facing roofs also work well, but north-facing roofs produce less.
- Roof condition: Your roof should be in good shape before installation.
- Space: Solar panels need around 2 square meters each, so you’ll need enough roof space.
- Shade-free area: To maximize energy, avoid shading from trees or buildings between 10 AM and 4 PM.
Moving Homes with Solar Panels
If you plan to move in the next decade, solar panels may not be worth it, as it takes around 13 years to recover installation costs. Removing and reinstalling them is costly, and they may not perform as well on a different home.
Maintenance and Lifespan
Solar panels require minimal maintenance. Rain usually keeps them clean, but you should trim nearby trees to prevent shading. The inverter, a key part of the system, may need replacing after 10 years, costing around £800.
Conclusion
Solar panels can significantly reduce your electricity bills and earn you extra money through the SEG scheme. However, it takes over a decade to recover the installation costs, making them a worthwhile investment only if you plan to stay in your home long-term.
