Sunsave Standard
Take control of your energy bills
Get payback in as little as six years with a premium solar and battery system. And sell any excess electricity to the grid.
- Starting from £6,500
- Complete solar and battery system
- Hassle-free installation
Reduce your reliance on the grid
Your Sunsave Standard solar and battery system will cut your electricity bills from day one. Here’s how it works.
- We go to your property and install your high quality solar panels and battery.
- Your solar panels generate electricity throughout the day, even in winter. If you’re not at home to use it, it goes into your battery.
- All the solar-generated electricity you don’t use will automatically be sold to the grid.
- Nothing goes to waste. You either use the electricity or get paid for it. Simple.
Get payback in as little as six years
With a Sunsave Standard solar and battery system, your electricity bill savings and export income mean you’ll gradually recover the money you originally spent.
Even before the energy crisis, electricity prices have increased by 5.5% each year on average since 2000. Nobody can predict the future, but in this scenario we’ve assumed the same inflation going forwards.
Over the first 20 years of having the system, you could save £37,073 and pay back the cost in as little as six years — after this, you’ll be making pure profit.
Our calculations
- Electricity price change taken from ONS Consumer price inflation time series (MM23), showing 5.5% average increase between 2000-2021. Nobody can predict the future, but in this scenario we’ve assumed the same inflation going forwards.
- Our example is based on a typical 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 system costs £8,249 upfront and generates 5,950kWh of electricity each year, using 28% at home and selling the other 72% to the grid (earning up to 28.1p per kWh through the Octopus Flux tariff).
- Savings are calculated using System Advisory Model (SAM) which takes into account smart battery controls to maximise export savings.
- This system would also save 1.5 tonnes of CO2 each year, which over its lifetime is equivalent to 32 long-haul flights.
Our calculations have been checked and approved by EVPS. It’s a national certification standard that validates how installers calculate energy-saving estimates.
Get fast access to the best export tariffs
We’ve partnered with Octopus to make it easy to access the best export tariffs, like Intelligent Octopus Flux. Together, we’ll ensure you start getting market-leading rates for your excess energy as quickly as possible.

Why go solar?
With a solar and 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 £600 per year). Combining these savings, your annual electricity bills can fall by 89%.
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’re 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 950kg per year, equivalent to a 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 an average of 32 different solar and battery system designs from Sunsave’s database, using properties from all over England and Wales. Each system in this sample uses 430W solar panels and a 5.8kWh battery, and is signed up to the 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
- The chart is based on the same typical four-bedroom family home in Essex using 4,000kWh of electricity each year, with a 6kWp solar panel system and a 5.2kWh battery.
- We’ve calculated this electricity generation using EnergyPlus solar irradiance data, plus the orientation and angle of the property’s roof.

Frequently asked questions
Is my roof suitable for solar?
Most roofs in the UK are suitable for solar panels. Your roof needs to be strong enough to support the weight of solar panels, but this is rarely a problem in UK homes.
We’ll inspect your roof before going ahead with installation. If we have any doubts, we’ll let you know.
It’s also important that your roof can maximise the output of your solar system. The optimum UK roof for solar panels is south-facing with 0% shading and angled at 35-40 degrees. But this doesn’t mean other roofs can’t have an effective solar system.
East-facing and west-facing solar panels can be very productive. We can install panels on a north-facing roof, but we don’t recommend it. There’s very little sunlight so you won’t generate as much electricity.
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 £600 per year). Combining these savings, your annual electricity bills can fall by around 89%.
These figures are based on an average of 32 different solar and battery system designs from Sunsave’s database, using properties from across the UK. Each system in this sample uses 430W solar panels and a 5.8kWh battery, and is signed up to the 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.
What’s Sunsave Standard?
Sunsave Standard is our traditional solar and 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.
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 35.8p per kWh and is only available to Octopus customers.
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.
Are you accredited and what do the accreditations mean?
We’re fully accredited by MCS, EPVS, HIES, NAPIT 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. HEIS also provide 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.

When will I break even on my solar panel system?
Most people see solar panels as a long-term investment, so it’s understandable that you want to know when you’ll pay back the initial cost. The answer to this question depends on many factors, including:
- price
- system size
- property location
- roof direction and angle
- export tariffs
- cost of electricity
- weather
- solar panel quality
For example, some properties might recoup the cost of their system in as little as 5 years, whereas others might take closer to 15.
