How Much Can You Save with Solar Panels in the UK? A Cost Breakdown
Switching to solar energy is an investment that not only helps the environment but also significantly reduces your electricity bills. For UK homeowners and businesses the rising cost of grid electricity has made solar photovoltaic (PV) systems more appealing than ever. But how much can you save by going solar? Let’s break down the costs and savings to help you understand why investing in a solar PV system with battery storage is a smart choice.
Upfront Costs of Solar Panels in the UK
The initial cost of installing a solar PV system varies based on the size and complexity of the setup. For an average UK home, the cost of a 4kW system, which is suitable for a medium-sized household, typically ranges from £5,500 to £8,000.
Adding a battery storage system increases the upfront cost but dramatically enhances the value of your system. A typical battery can cost between £3,000 and £6,000, depending on capacity and brand. While this increases the overall investment, it allows you to store excess energy for later use, maximising your savings.
Government Incentives and Financial Support
The UK government’s Smart Export Guarantee (SEG) allows solar panel owners to sell excess electricity back to the grid. The rate you’ll earn varies depending on your energy provider but can add up to £100–£200 per year for an average household.
Additionally, solar panels are exempt from VAT in the UK for most installations, reducing the upfront cost by 20%. These incentives help make solar PV systems more affordable and attractive.
How Much Can You Save on Energy Bills?
The real savings from solar panels come from reducing your reliance on grid electricity. Let’s break this down:
- For an average household (4kW system):
A 4kW solar PV system can generate around 3,400 kWh per year, enough to cover approximately 60% of a typical UK home’s electricity needs. With electricity prices averaging around 34p per kWh, this equates to savings of £1,156 per year. - With battery storage:
Without a battery, any excess energy generated during the day is sent back to the grid. With a battery storage system, you can use this excess energy at night or during high-demand periods, increasing your self-consumption to up to 80%. This can boost your annual savings to £1,500 or more, depending on your energy usage.
How Long Does It Take to Break Even?
The payback period for solar panels in the UK typically ranges from 4 to 8 years. Adding a battery may extend this to 10–15 years, but the increased energy independence and savings make it worthwhile.
Given that solar panels have a lifespan of 25–30 years you’ll enjoy substantial savings for decades after breaking even.
Additional Savings for Businesses
For UK businesses, the savings are even greater. Commercial properties often consume more electricity during the day, aligning perfectly with solar energy production. Businesses can reduce operational costs, earn from the SEG, and benefit from tax advantages such as the Capital Allowances Super Deduction.
Why Now Is the Best Time to Switch to Solar
With energy prices rising and government incentives in place switching to solar power has never been more beneficial for UK homeowners and businesses. Solar PV systems with battery storage offer a reliable, long-term solution to control your energy costs and achieve energy independence.
