What is solar power?
Solar panels take advantage of nature’s most powerful resource: the energy produced by the sun. Solar panels, also known as photovoltaic systems (PV systems), use semiconductor technology to convert energy from sunlight into electricity that can power your household
How does Solar & Storage work?
Using daylight to power your home
Solar panels absorb energy from daylight and convert it into electricity. When daylight hits the panel it is converted into Direct Current (DC) which flows to an inverter. This inverter converts the electricity from DC to Alternating Current (AC), the standard electricity that comes out of power outlets. Batteries work much like the name suggests - storing electricity to be used at another time.
Is solar worth the investment?
Solar panels can increase the value of your home as well as making it more energy-efficient
The payback period for solar panels is getting shorter year-on-year with the increase in energy prices - you can lower your energy costs by up to 90%
Not only is solar power good for the environment, but you can even earn money back for surplus energy exported back to the grid
Are solar panels right for me?
A few things which could influence your solar installation to keep in mind.
An unshaded, South facing roof is ideal for maximum electrical output. East or West facing roofs could still be considered, and even North facing roofs can work in some situations. Get in touch with us to find out.
If you live in a listed building, conservation area or national park, you would need to get permission to get a solar panel installation.
You need a strong enough roof to support the weight of the solar system. If your roof isn’t suitable, no worries, we could still offer you a storage solution.

Questions about solar?
How do I know if solar is suitable for my home?
Solar panels are generally suitable for most homes and our team of experts are on hand to use satellite images to talk things through with you over the phone.
However, some of the most common reasons a home would not be suitable are:
• not enough roof space (an 8-panel system requires a space of 2 small car parking spaces)
• roof is in a state of disrepair or very unstable
• roof is thatched or natural stone
• very uneven roof or lots of obstacles (like lots of skylights or dormer windows)
Are solar panels a worthwhile investment?
Especially with electricity prices from your energy supplier ever increasing, solar panels are a handy way of taking the cost of powering your home into your own hands. Our solutions will still be generating clean energy for you in well over 20 years.
They’re a great way to boost your home’s green credentials too - as it doesn’t get any cleaner or greener than generating your own solar energy to use to power your home or an electric vehicle. There is also increasing evidence that solar panels can increase the value of your home, as more and more prospective buyers actively seek homes with renewable technologies already installed.
Do I need planning permission for solar panels?
In many instances, the installation of solar panels is covered by the General Permitted Development Order and therefore does not require planning permission.
However, you should check with your local planning authority if you live in a:
• conservation area
• area of outstanding natural beauty
• national park
• listed building
How do I decide the right size and location for my solar system?
After an initial chat with our sales team over the phone, one of our expert designers will visit your home to assess your roof for available space, check for any shading or obstacles that could obstruct the sun, and analyse the optimal location on your roof to install your new panels.
Shortly after their visit, they’ll send you a proposed design with some options around number of panels, exactly where they can be located on your roof, and an optional upgrade to add a battery to store up any excess solar you generate. After that, it’s up to you how green you want to go!
What’s involved in a solar panel installation?
Solar panel installations will almost always require scaffolding to allow our team to safely access the roof. An installation job will generally run over a day or two and involves securely fixing your new panels to your roof, wiring up all the associated cables, and then setting up your inverter (which is what takes the electricity generated by your panels and turns it into electricity that can be used in your home).
Once that’s all complete, our installers will talk you through a detailed handover and also set you up with a solar monitoring app so you can track how much clean energy you’re generating through the year.
Questions about storage?
What battery storage options are available?
We offer a range of home batteries with storage capacity from 5kWh to 13.5kWh. To make sure you have plenty of storage capacity, to collect any excess solar energy generated, to use later when you need it (even when the sun has gone down).
I’m thinking of getting solar panels, should I get a battery too?
A home battery is a great way to ensure that you store any excess energy you generate from your solar panels to use later in the day when you need it – for example, in the evening when the sun has gone down. Especially if you’re not using as much energy during the day when your solar panels are generating energy, a battery makes sure you don’t lose out on that hard earned green energy – as without a battery, if you don’t use your solar energy it gets lost to the electricity grid. This means you’d instead have to rely on more expensive, less green energy from energy suppliers instead.
Also, installing a battery at the same time as your new solar panels means your battery qualifies for the same VAT rate as solar (instead of 20%) – so getting them together gives you an extra smart saving!
How can I monitor how much energy my battery is storing?
All of our home battery options come with an app which allows you to monitor the performance of your solar and battery system, including a live view of how power is moving between your solar panels, your battery, and your home.
Should I get a battery if I don’t have solar panels?
You absolutely can – but you should consider the benefit of doing so, which is significantly less if you don’t have solar panels. It is possible to sign up to a “time of use” tariff from your energy supplier (e.g. Economy 7) which would allow you to charge up with cheaper electricity overnight to use during the day for a modest saving, but with energy prices constantly changing we advise you give it some real thought first.
