We’ve been harnessing the sun for over 20 years, 10 of which we’ve been a Which? Trusted Trader. Here’s 5 things you need to know if you’re thinking of taking the leap and going solar.
1. You really can lower your energy bills. A well designed solar system can generate the same amount of energy as you use over the course of a year. With a solar PV system paired with a battery such as Tesla Powerwall, you can get very close to self-sufficiency for a portion of the year, dramatically reducing what you buy from the grid.
2. Earn money from surplus energy. You can sign up for the Smart Export Guarantee, where you'll be paid for energy you export from your solar system back to the grid; so the power you generate but don't use still earns you something.
3. Reduce your carbon footprint. A good quality solar PV system is a great investment for your home, as it reduces your carbon footprint.
4. Battery storage makes it even smarter. Battery storage lets you store excess solar energy for later use, and during winter you can use your battery to buy in cheap off-peak electricity from the grid.
5. Solar is more affordable than ever. And renewable technology is getting smarter so even smaller roofs work too.
