Solar Panel Installation

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.

Yes, solar panels are effective in the UK’s climate. Despite the UK’s reputation for cloudy weather, solar panels don’t require direct sunlight to generate electricity; they can still produce energy on cloudy or overcast days. The efficiency of solar panels has improved significantly, making them more capable of capturing sunlight in less sunny conditions. Additionally, cooler temperatures can actually enhance solar panel performance, as excessive heat can reduce efficiency. With advancements in technology and the UK’s commitment to renewable energy, solar panels remain a viable and effective option for generating electricity, even in its varied and often cloudier climate.

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

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.

Yes, installing solar panels can increase your property’s value, but the extent varies. In areas with high electricity costs or where environmental sustainability is valued, solar panels can be particularly beneficial. They offer energy cost savings, which are attractive to potential buyers. However, the impact on property value depends on market trends, the attractiveness of green energy in the area, and the specifics of the solar installation, like ownership and efficiency. Generally, solar panels are seen as a value-adding feature in the real estate market, making properties more appealing and potentially leading to a higher resale value.

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.

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.

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.
