Will I pay off my system before warranties run out?
In most cases, yes. Payback is subject to many factors such as usage, tariff and system size, but as a guide solar pays for itself in about 5 to 7 years, a battery in about 10, and solar plus a battery in 6 to 8 (as of October 2026). Quality panels now often carry 25-year warranties, and good inverters and batteries usually carry around 10 years. So a well-chosen system should pay for itself within its warranty period. We give you a realistic estimate for your home before you buy.
