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.

Benefits

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.

    Sunlight

    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. 

    Location

    If you live in a listed building, conservation area or national park, you would need to get permission to get a solar panel installation. 

    Roof

    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. 

    Even though every home is a little bit different, most homes in the UK are suitable to install and benefit from solar. It’s the perfect choice if you're looking to reduce your energy bills and do your bit for the environment. The main things to watch out for are obstacles (skylights or dormer windows), too much shading, not enough roof space and poor roof condition. Our team of experts is on hand to use satellite images to talk these things through with you as part of the process here at Egg.

    Most studies have shown that powering your home with solar could cut your energy bills by as much as 90%. 90% savings over the duration of your 25-year performance warranty, is a lot of potential savings, so we think it's a no-brainer! There is also increasing evidence that solar panels can increase the value of your home, as more and more prospective buyers are looking for homes with renewable technologies already installed.

    Solar panels are most efficient when they receive direct sunlight. However, they can still produce electricity on cloudy or overcast days and even in indirect or diffuse sunlight (luckily for us in the UK).

    In short, Yes! Solar panel systems continue to generate electricity during the winter months, although their efficiency may be reduced compared to the rest of the year due a few factors, mainly the reduced number of daylight hours and a change in the angle of the sun.

    Solar panels are built to endure and are designed for a long and productive life. On average, you can expect your solar panels to keep producing clean, green energy for an impressive 25 to 30 years. Some may even continue working effectively for 40 years or more! So, if you're pondering the benefits of solar energy, rest assured that your investment will continue to shine for many years to come.

    In the UK, the best direction for solar panels is south-facing. Solar panels installed on a south-facing roof will receive the most sunlight throughout the day, maximising energy production. If you don't have a south-facing roof though, all is not lost, solar panels are still effective even if they don't face south. Our team of experts can help you understand how much you could generate if you have an East, West or North facing roof - you might be surprised!!

    Most installations of solar panels are considered to be a 'Permitted Development' and therefore don't 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

    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).

    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!

    All of our home battery options come with an app which allows you to monitor the performance of your solar panel and battery storage system, including a live view of how power is moving between your solar panels, your battery, and your home.

    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.
