If you’ve been researching solar panels for your home, one question comes up more than any other: how much does it actually cost? In this guide, we break down real installation prices, what affects them, and how Scottish homeowners can cut the cost with grants and 0% finance.
The average 4kW solar PV system in Scotland costs between £6,000 and £9,000 fully installed, depending on roof type, panel brand, and whether you add battery storage. Adding a battery typically increases the price by £3,000 to £5,000, but can push your self-consumption of generated electricity from around 40% up to 80% or more.
Every Speedy Solar installation is MCS certified, which means you qualify for the Smart Export Guarantee (SEG) and any available Scottish Government grant funding. We also offer 0% and low-rate finance through Ideal4Finance, so you can spread the cost while your system pays for itself through lower energy bills.
