Thinking about solar for your UK home? You’re not alone—two of the first questions we hear are: “How much can I actually save?” and “Is exporting energy back to the grid profitable?” Here’s what to expect, plus tips to maximise your return.
How Much Can I Save With Solar Panels in the UK?
Most households save between £400 and £700 per year with a standard 4 kW PV system. With energy prices elevated, some save even more—especially when adding battery storage to maximise self-consumption.
Key factors influencing your savings:
• Annual electricity usage
• Electrification plans (EVs and/or heat pumps)
• Size and orientation of your solar array
• Whether you add battery storage
• Your electricity tariff
Example: A family in Warwickshire with a 4 kW system and battery storage reduced their annual bill by over 75%, including winter months.
Yes—exporting surplus energy is profitable thanks to the Smart Export Guarantee (SEG). Any electricity you don’t use is exported to the grid, and your supplier pays you for every kWh.
Typical SEG rates: ≈5–20p/kWh, supplier-dependent.
Annual earnings example: export 1,000 kWh at 15p/kWh = ~£150 per year—on top of bill savings.
Pro tip: compare SEG tariffs regularly and shift high-use appliances (e.g., washing machine) to sunny hours to boost self-consumption.
- Usage patterns: daytime use increases savings.
• Battery storage: increases self-consumption—reduces exports but avoids costly evening imports.
• System size: larger systems generate more; ensure roof/budget fit.
• SEG rate: choose a competitive export tariff.
Using your own solar energy is usually more valuable than exporting it. You avoid the full import cost (often 25–35p/kWh), while SEG payments are typically lower (≈5–20p/kWh). Batteries help you use more of your own energy after dark.
Solar output drops in winter due to shorter days and lower sun angles, but systems still generate electricity—and every unit you use or export adds up. Many customers see the largest savings in spring and summer; in December–January, solar still offsets peak-time imports.
Most UK systems pay for themselves in ~6–10 years, depending on system size, usage, and tariff rates. Panels typically last 25+ years, so you benefit for decades. (Assumes typical import tariff and usage; we model this per home.)
Absolutely. Battery storage lets you store daytime solar for evening use, and smart controls can automate appliances to run when your panels generate the most power.
