Every business premise is unique. Solar works well if you have an inclined roof, providing the top is facing South, SE or SW. A flat roof gives you more options. We partner with leading manufacturers of mounting solutions to maximise the saving potential for any roof space. And we use data modelling to help you understand how solar will perform on your roof so you know what to expect.

There is no minimum, but the more space you have for the panels, the better the return on investment as you benefit from economies of scale. But remember, converting an asset – such as a roof – into an energy-generating asset will always be better than doing nothing.

Yes. Solar panels are made from solar photovoltaic cells that generate power from daylight, not sunlight or heat. Your solar panels will usually get more light when the sun is highest in the sky and on a clear sunny day when the light is brightest. Our team will model how much energy you can expect to produce in a typical year based on your geographic location with additional feeds from historical weather databases.

Panel choice will combine several factors; availability of space, design of the array, performance, value for money, track record and guarantees. Our design engineers can advise you on the best options to suit your needs. We only use panels that we know will give you the performance you need.

Not only are solar panels remarkably reliable, but they’re now made to last more than 25 years. In addition to decades of effective performance, all of Repsole’s solar manufacturing partners provide minimum performance guarantees of over 80% of their original generation potential after 20 years.

Solar alone will not give you electricity 24 hours a day as they only produce electricity in daylight hours. However, in combination with alternative energy sources, a battery system, and solar PV panels, you could become independent from the national electricity grid. But this needs to be designed by our team to ensure that your generation, storage and use balance never leaves you in the dark.

In theory, if you are going to be off-grid – nothing! But, to get the best possible returns and protect your investment, some things need careful design, and that’s where we come in—like planning the system, maximising space and generation and considering shading and structural loading of the roof. If you want to be attached to the grid, any system will need prior permission from the local grid operator (DNO). We make these applications for you, which can take 90 days to approve.

No. Amendments to the Town and Country Planning Act (1990) have changed how non-domestic installations are treated under permitted development in England. Solar PV systems up to 1 MW are permitted on walls and roofs subject to several conditions, which we can take care of for you through the design process.

Whilst every roof is different, once you have done the planning and received a positive response on the G99 application, the installation estimate will usually be just 1 to 4 weeks for any system up to 500kWp. Installation is non-intrusive so that business can carry on as usual. Note – the final link up to the grid will require a power-off. We can do this once your business has shut down for the day, so your staff won’t be impacted.

For businesses, the electricity generation and usage profiles usually run closely from sunrise to sunset. There is little waste, and solar panels are highly cost-efficient. However, some clients want to maximise their use of the power they generate ‘behind the meter’. A battery design integrated with the solar panels is a great option. This works out particularly well if your company is shut at weekends because that’s when nearly 30% of your weekly power is generated. Instead of exporting your energy back into the grid for a minimum price, you can store it up and use it on the weekdays. Or you can save it for your Electrical Vehicle chargers, giving your fleet, employees, and clients 100% renewable power for their vehicles.

No. Solar panels have 25-year performance warranties that they won’t degrade more than a certain amount per year, giving you confidence in their performance for that period. Most batteries have 10-year warranties, and tests suggest that the typical battery will degrade by 3% or more annually. The more you use a battery, the more it degrades in terms of energy storage capacity. Anyone with a mobile phone will have experienced this degradation!
