Potential energy price rises graph

Why go solar?

With a solar & battery system, you’ll be buying less electricity from the grid and you’ll be able to sell any excess electricity to the grid (earning on average £350 per year). Combining these savings, your annual electricity bills can fall by up to 103%.

Even before the energy crisis, electricity prices have increased by 5.5% each year on average since 2000. Nobody can predict the future, but they are expected to remain high until at least the late 2030s, so your system will protect you against rising energy costs. It could also increase the value of your property by up to £11,157.

Your household carbon footprint will drop on average by 1,100kg per year, equivalent to a return flight from London to New York. Over your solar panels’ lifespan, this adds up to 30 flights. So you’re not just saving money — you’re helping the planet, too.

Our sources
  • The savings figures are based on a household experiencing average UK irradiance with a 4.4kWp solar panel system and a 5.2kWh battery, using 3,500kWh of electricity each year and signed up to the Intelligent Octopus Flux export tariff
  • If you opt for Sunsave Plus, your savings will work a bit differently, but you could be looking at more money in your pocket each month — even after the monthly payments. Learn more about savings with Sunsave Plus.
  • Electricity price change taken from ONS Consumer price inflation time series (MM23), showing 5.5% average increase between 2000-2021. For our forecast, we’ve assumed the same rate of inflation over the next 20 years and the energy bills are based on a household using 4,000kWh of electricity each year.
  • A Cornwall Insight forecast in July 2023 predicts that power prices will remain high until the late 2030s.
  • Adding solar to a property with a D-rated EPC usually increases the rating to a C. An August 2023 Rightmove study found that increasing your EPC from D to C results in an average property price increase of 3%, or £11,157.

Solar works all year round

Solar panels work all through the year — even in the UK! All they need is a bit of daylight.

Your solar panels generate the most energy in summer. This is when you’ll sell the most excess electricity to the grid. Your solar panel output will drop in winter, but won’t stop completely. You’ll just need to top up with electricity from the grid.

Our sources
  • Our example is a four-bedroom family home in Essex using 4,000kWh of electricity each year with a 6kWp solar panel system and a 5.2kWh battery.
  • This electricity generation has been calculated using EnergyPlus solar irradiance data, as well as the orientation and angle of the property’s roof.

Frequently asked questions

How much money will I save going solar?

With a solar and battery system, you’ll be buying less electricity from the grid. You can also sell any excess electricity to the grid (earning on average £350 per year). Combining these savings, your annual electricity bills can fall by up to 103%.

These figures are based on a household experiencing average UK irradiance with a 4.4kWp solar panel system and a 5.2kWh battery, using 3,500kWh of electricity each year and signed up to the Intelligent Octopus Flux export tariff.

If you sign up for Sunsave Plus, your savings will work a bit differently. But you could have more money in your pocket each month, despite the monthly payments. Find out more about savings with Sunsave Plus.

These figures are all estimates and every household is unique. Your exact savings with a solar and battery system will depend on a number of factors, including how suitable your roof is, where your property’s located, and your annual electricity consumption.

For a better estimate of how much you could save, try our online savings calculator and book a call with one of our friendly solar experts.

Can I sell my excess solar energy to the grid?

Yes. Whenever you generate more electricity than you need (or can fit in your battery), you can sell it to the grid through a scheme called the Smart Export Guarantee (SEG).

All UK energy suppliers with over 150,000 customers have to offer a price to households that export renewably-sourced electricity. Smaller energy suppliers can opt in, too.

Your export tariff provider doesn’t have to be the same as your energy provider, but many energy suppliers offer better rates to customers.

The best available rate is currently Intelligent Octopus Flux. It pays up to 30.3p per kWh (on average) and is only available to Octopus customers.

What’s Sunsave Plus?

Sunsave Plus is everything you need to go solar, delivered as a 20-year subscription. It includes the design, supply, financing and install of a system tailored to your home, plus ongoing monitoring, maintenance and insurance through the Sunsave Guarantee for the length of your subscription. Learn more about Sunsave Plus.

What’s Sunsave Standard?

Sunsave Standard is our traditional solar & battery solution, with upfront payment. Our solar experts will create a bespoke design tailored to your household, taking into account a whole range of factors including the size of your roof, your annual electricity consumption, and your budget. We use premium kit, and all of our Sunsave Standard systems come with a two-year workmanship warranty. From site survey to scaffolding, we’ll take care of everything. Once we’ve started, your installation will be complete in a few days.

We typically take a 15% deposit when you sign the contract (you can pay by bank transfer or card), and the remainder after we’ve installed your system. Learn more about Sunsave Standard.

What are the benefits of installing a battery with solar panels?

Adding a battery to a solar panel system means you can store excess electricity that you would otherwise have exported to the grid.

If you’re out during the day and your solar panels are producing electricity, this goes into your battery to use in the evening. Most solar systems have a battery sized according to your property, so it should provide enough electricity for the night before it needs recharging.

A solar battery also works well with time of use tariffs. It allows you to buy and store cheap night-time grid electricity to use later in the day when electricity would normally be much more expensive.

We’ll make sure you are on the best tariff to maximise your solar savings day and night. So you can sit back and enjoy the extra cash.

How do you ensure the highest quality installations?

We’re a Which? Trusted Trader and are fully accredited by MCS, EPVS, HIES, NAPIT and TrustMark. Our dedicated in-house team has decades of solar experience and manages your solar installation from start to finish, working exclusively with MCS-accredited subcontractors to ensure your system is built to last. We handle everything from design, DNO application, survey, supply and install, monitoring and financing — so you don’t need to lift a finger.

Are you accredited and what do the accreditations mean?

We’re fully accredited by MCSEPVSHIESNAPIT and TrustMark. Find out more about what these accreditations mean below.

The Microgeneration Certification Scheme (MCS)

MCS certifies, assures quality and provides consumer protection for microgeneration installations and installers, including solar PV. We’re a member of MCS, so you can be assured your solar PV system will be installed to a high standard and built to last. With your MCS certificate, you’re eligible to sign up to an SEG (Smart Export Guarantee) tariff with an energy supplier to make money from your excess electricity.

Energy Performance Validation Scheme Gold (EPVS Gold)

EPVS is a certification standard that ensures solar PV and battery energy-saving estimates are accurate by validating installers’ processes. Our EPVS Gold rating means we’re best in class for the accuracy of our savings calculations. So when you choose Sunsave, you’ll know that an independent third party has validated the individual energy-saving estimates in your proposal.

The Home Insulation and Energy Systems Quality Assured Contractors Scheme (HIES)

HIES is CTSI-approved Consumer Code that gives you protection for renewable energy installations, including solar photovoltaic panels, batteries and inverters. When you install solar with Sunsave, HIES protects any deposit you’ve made to us in the event that we can’t install your solar system. Through their insurance-backed guarantee, they ensure your workmanship guarantee is upheld, in the unlikely event that we can’t. HIES also provides a fair and independent arbitration mechanism if you believe that we haven’t delivered the installation experience you expected.

TrustMark

TrustMark is the Government Endorsed Quality Scheme that covers work you choose to have carried out in or around your home. We’ve been vetted to meet TrustMark’s high standards and have made a commitment to provide good customer service.

  • We’ve hired a talented team with decades of experience in the solar and energy industries.

As a safety net, the HIES consumer protection scheme provides deposit and payment insurance, as well as an insurance-backed guarantee that protects you in case Sunsave stops trading.
