How much does a solar panel cost per kilowatt?

Exactly how much a solar panel costs per kilowatt depends on the type of solar panel you're talking about. Monocrystalline solar panels are the most expensive, and their cost per kW is somewhere around £1,000 – £1,500 whereas polycrystalline solar panels cost about £900 per kW.

How much does a 3.5 kWp solar panel system cost?

A 3.5 kWp solar panel system would typically require around 10 solar panels (at 350 W each) and cost between £5,000 and £10,000. *kWp stands for ‘kilowatt peak’. This is the amount of power that a solar panel or array will produce per hour in prime conditions.

How much does a solar & battery system cost?

The average cost of a 3kWp solar panel system for a typical property with two or three bedrooms is about £9,000, including installation. This jumps up to around £11,000 if you’re adding a 5kWh battery. This is a great time to get a solar & battery system, as there’s currently 0% VAT on both panels and batteries.

How much do solar panels cost in the UK?

Solar panels cost in the UK around £7,000 for an average three-bedroom home, £9,000 including a battery. For those considering switching to solar energy, the potential savings of £917 each year – which can amount to over £27,000 across the panels’ 30-year average lifespan – is one of the most appealing factors of installing a solar panel system.

What costs should you consider before installing solar panels?

There are two other potential costs you should look into before installing solar panels, these are maintenance costs and repair costs.

Why do solar panels cost so much?

The number of solar panels required for a solar energy system is a key determinant of the overall cost as it directly influences both the initial investment and long-term financial benefits. More panels naturally lead to higher upfront costs due to the price of the panels themselves.
