☀️ Are solar panels actually worth it?
It's a question we get asked more than any other, whether it's about a home or a business, and it's a fair one to ask before making that kind of investment.
For homes: a typical 4-kilowatt (kW) solar-only system costs around £5,000–£8,500 to install and can save up to £1,000 a year on energy bills. Add a battery and that return climbs further. Most homeowners reach full payback within 8 to 12 years, and across a 30-year system lifespan, that can add up to more than £50,000 in savings.
For businesses: the numbers work differently, but the answer's usually the same. Most commercial sites we work with pay back their system within 5 to 8 years, then spend the rest of that system's 30-year lifespan benefiting from low-cost electricity.
In both cases, the return depends on your roof's orientation, how much shading you get, and when you use most of your electricity.
