How Much Could Property Owners Save With a Solar and Battery System in 2026?

With electricity prices still sitting well above pre‑crisis levels, more property owners across East Sussex are turning to solar and battery storage as a way to take control of rising energy costs. The financial benefits are now clearer than ever - and for many homes, the savings are far greater than expected.

Here’s a breakdown of what property owners can realistically save in 2026.

Lower Monthly Electricity Bills

A well‑designed solar system can significantly reduce the amount of electricity a property needs to buy from the grid. Even on cloudy days, modern panels continue generating power, helping to cut daytime usage.

For a typical 3–4 bedroom home, this often means:

• £600–£1,000 per year saved from solar generation alone
• Reduced exposure to peak‑rate electricity
• More predictable long‑term energy costs

Homes with higher daytime usage - such as home offices, families, or properties with electric heating - can save even more.

Even Bigger Savings With a Battery System

Adding a battery is what unlocks the full financial value of solar. Instead of exporting excess energy for pennies, homeowners can store it and use it during the evening when electricity is most expensive.

A solar + battery setup can:

• Reduce grid reliance by up to 80–90%
• Avoid peak‑rate charges
• Provide backup power during outages
• Maximise the return on every unit of solar energy generated

With a battery, many homes see £1,000–£1,600+ in combined annual savings and export earnings.

Earnings Through the Smart Export Guarantee (SEG)

Any unused solar energy can be exported back to the grid, earning property owners additional income.

Typical SEG earnings:

• £80–£200 per year, depending on system size and tariff
• Higher export rates available with flexible suppliers
• Extra income even during lower‑usage months

It’s a simple way to boost the overall return on investment.

Shorter Payback Periods

Thanks to higher energy prices and improved technology, payback times have become much more attractive.

Most property owners now see:

• 6–9 year payback for a solar + battery system
• 20–25 years of performance from the panels
• 10–15 years of performance from the battery

This means a decade or more of pure savings once the system has paid for itself.

Increased Property Value

Solar and battery systems are becoming a sought‑after feature for buyers who want lower bills and greater energy independence.

Benefits include:

• Higher resale value
• Faster sale times
• Strong appeal to eco‑conscious buyers
• Reduced running costs for landlords and investors

For rental properties, solar can also make EPC improvements easier and more cost‑effective.

A Long‑Term, Future‑Proof Investment

Solar and battery systems offer a combination of savings, stability, and independence that few other home upgrades can match. With long warranties, low maintenance, and proven performance, they continue delivering value year after year.
