One UK household watched the England vs Mexico match on free electricity, not from a dodgy stream, but from solar panels on their roof. The owner told The Eco Experts they generated enough power during the game to cover the TV, lights, and even the kettle without drawing a single kilowatt from the grid.
As reported by The Eco Experts, the homeowner used a 4kW solar array and a small battery to shift the daytime generation into the evening. It is a neat story, but what does it mean for the average household weighing up solar?
What it costs a typical 3-bed semi
A 4kW solar photovoltaic system, the most common size for a semi-detached house, costs between £5,000 and £7,000 fully installed, according to the Energy Saving Trust. On a sunny June day, that system can generate 20-25 kWh. A typical evening’s viewing (TV, lights, broadband, fridge) uses about 2-3 kWh. The rest can be exported under the Smart Export Guarantee at 4-15p per kWh, depending on your supplier. Octopus Energy’s Outgoing tariff pays 15p/kWh; others pay less. Over a year, a household can save £200-£300 on bills and earn £80-£120 from exports.
The catch: winter and the evening gap
But the England game kicked off at 5pm BST in June. Solar generation peaks at midday and falls sharply after 4pm. Without a battery, the homeowner would have been drawing from the grid by half-time. Batteries add £2,000-£4,000 to the system cost and typically store 5-13 kWh, enough to cover evening peaks but with a payback period of 7-12 years. Ofgem notes that households on time-of-use tariffs (like Economy 7 or Agile) can shift loads to cheap night rates, but solar-plus-battery remains the only way to truly watch football for free.
EPC impact and resale value
Solar panels can lift an EPC rating from D to C or C to B, depending on existing insulation and heating. That matters because from 2025, landlords must meet a minimum EPC C for new tenancies, and owner-occupiers increasingly see it as a selling point. A 2023 study by the Department for Energy Security and Net Zero found that homes with solar sell for 1-2% more on average, roughly £3,000-£6,000 on a £300,000 property. The upfront cost is still the barrier: grants like the Boiler Upgrade Scheme apply only to heat pumps, not solar. The ECO+ scheme covers insulation and low-income households but rarely PV.
What to do now
Check your roof orientation, shading, and local installer pricing via the MCS database. Get at least three quotes. If you are on a standard variable tariff, compare export tariffs now, some suppliers pay more for midday generation. For the next England game in July, you might be watching on your own electrons. But act before the summer sun fades: installers are booked 6-12 weeks ahead.
Frequently Asked Questions
Yes, if your panels generate enough power during the day and you have a battery to store it for the evening. Without a battery, you will use grid power after sunset. A typical 4kW system can cover evening viewing in summer, but winter generation is much lower.
A 4kW system costs £5,000-£7,000 installed. Adding a 5kWh battery adds another £2,000-£3,000. The Smart Export Guarantee can earn you 4-15p per exported kWh. Payback periods range from 8 to 15 years depending on usage and tariff.
