The Solar Landscape in Winchester

Environmental Impact and Solar Panels

The adoption of solar panels in Winchester is significantly contributing to reducing carbon emissions throughout the city. This shift is not only beneficial for the environment but also aligns with broader environmental goals and targets set by Winchester City Council.

Winchester’s Solar Market is on the Rise

In Winchester, the solar market has been undergoing rapid growth, driven by a surge in environmental responsibility and government support. This trend is marked by a significant increase in solar panel installations in various residential and commercial areas across the city.

Saving Money and Resources

Apart from the environmental and sustainability benefits, residents in Winchester are becoming more aware of the financial advantages of solar energy. Savings on electricity bills and potential income from excess energy production are key factors driving the adoption of solar panels.

Did You Know?

Winchester City Council have set a target so that the organisation is carbon neutral by 2024, and the wider district by 2030.

Solar Products

Explore our range of solar products, carefully sourced from reliable manufacturers and fully certified to MCS standards, ensuring optimal performance and reliability. 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 the UK 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 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 specification. 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.

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.

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

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.

Can solar panels work effectively in Winchester's climate?

Yes, solar panels are highly effective in Winchester’s climate. They don’t require direct sunlight to generate electricity, just daylight, making them suitable even on cloudy days – Winchester also has more than 1700 sunlight hours each year making the city one of best areas for solar power in the UK.

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

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

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.
