How much does a solar panel cost?

Solar panel costs have fallen by 90% worldwide, according to Our World Data. Since the 1970s, the cost of solar has dropped 99%, from around $100 per watt (£77.09) to just under $0.20 per watt (£0.15) today.

How much do solar panels cost in 2025?

The cost of solar panels in 2025 can range between £6,600 - £8,100 for a typical 2 to 3-bedroom home. However, there are several factors that can influence the cost, including: System size: Larger systems cost more overall but may have a lower cost per watt.

How is solar price measured?

The solar price for utility-scale projects is measured using LCOE, which typically has the lowest LCOE among all solar PV sectors. As solar prices continue to decline, utility solar PV plays a key role in the global energy transition, supporting large-scale renewable energy adoption.
