The Solar Landscape in London

London’s Market is Expanding

London’s solar market is experiencing a rapid expansion, driven by increased environmental awareness and supportive government policies. This growth is evident in the rising number of residential and commercial solar panel installations across the city.

Saving Money and Resources

Beyond environmental benefits, Londoners are increasingly recognising the economic advantages of solar energy. Savings on electricity bills and potential income from excess energy production are key factors driving the adoption of solar panels.

Technology is Changing

Technological advancements in solar panels, including higher efficiency rates and improved storage capabilities, are making solar installations in London more effective and less obtrusive, suitable for the city’s varied architectural landscape.

Did You Know?

A single relatively small commercial roof installation of 30 KW will save over 26 tonnes of CO2 emissions compared to fossil fuels.

Solar Products

Explore our range of solar products, carefully sourced from reliable manufacturers and fully certified to MCS standards, ensuring optimal performance and reliability for those in London. From advanced solar panels that harness sunlight, to cutting-edge battery storage systems, we provide practical solutions that lower costs and promote sustainability.

Solar Panel Maintenance

Solar PV systems are very reliable, but planned solar maintenance is essential to ensure continued high output efficiency. Many solar systems in London have been installed for several years now, some for over 5 years. Whilst most maybe running well, many owners don’t check their systems performance regularly and wouldn’t know if it was performing well or not.

Frequently Asked Questions

How do solar PV cells work?

Photovoltaic (PV) cells convert radiation from the sun into electricity.  A typical PV cell consists of a wafer of semi-conducting material, usually silicon, manufactured with two electrically different layers.  When sunlight hits the cell it excites the electrons within the silicon, creating an electric field across the layers and causing a flow of electricity.

Are solar panels effective in London's climate?

Yes, solar panels are effective in London despite its variable weather. Modern panels are designed to work efficiently in diffuse sunlight, making them suitable for London’s climate. They generate significant energy even on cloudy days, ensuring a reliable source of renewable energy throughout the year.

How much electricity do solar PV systems generate?

An optimally orientated, un-shaded 1kWp array will, each year, generate approx 850kWh (units) of electricity.

What size do solar PV panels come in?

PV systems are modular, allowing a great degree of flexibility in design and spcification. The physical size of individual panels varies. Smaller output panels tend to be smaller in size and the very high output panels are much larger. The size of an array is determined by the available roof space and energy requirement of the property. We work with our customers to ensure that we provide a system that meets their requirements and available roof space.

Will solar panels increase the value of my property in London?

Installing solar panels can potentially increase your property’s value in London. Buyers are increasingly seeking energy-efficient homes with lower running costs, making properties with solar installations more attractive in the real estate market.

Where can I place my solar PV panels?

Solar panels can be mounted in a range of locations, from a roof to the ground and even bespoke frames. We install on a range of roof types, including flat roofs. Ground mounted systems use ballast or specially designed mounting frames. Solar panels are best if they are south facing, but east and west facing roofs are are suitable, although output will be slightly less. A roof pitch of between 10 and 50 degrees is best and preferably with little or no shade. If shade cannot be avoided then we can include optimisers to reduce the shading impact.

Why is shade a problem for solar PV systems?

Any shade, such as from trees or neighbouring buildings, can have a large impact on the performance of a PV system. Because modules are constructed from a number of PV cells interconnected together, if one cell is shaded it has a knock-on effect that prohibits the whole module from generating electricity. To work effectively, we recommend that whole PV array needs to be free from shade for the majority of the day.

Do I need planning permission to install solar panels in London?

Most of the time the answer is no. However, if you live in a protected area such as an Area of Outstanding Natural Beauty or a National Park such as the South Downs, then you may need permission, but not always. We can advise you on this.. Some authorities will ask that you have a bat or bird survey first or that your system meets certain aesthetic criteria such as it being an ‘in-roof’ system where the panels sit flush with the roof tiles. We can work with your needs and design a system that meets the necessary criteria. Some new build properties may also have restrictions on what can be installed. In these cases, we recommend that you check with your estate management company.
