Commercial Solar Panels Dorset

Commercial solar installers based in Dorset
Commercial solar panels for Dorset businesses, designed and installed by our own team

From Poole and Bournemouth to Wimborne, Ferndown, Portland and the farms of North Dorset, we design and install rooftop and ground-mounted solar PV, battery storage and EV charging for businesses, schools, farms and community buildings.

DES Renewable Energy is an MCS certified solar installer and NAPIT approved electrical contractor with our head office at Woolsbridge Industrial Estate in Three Legged Cross, near Wimborne. Dorset is our home patch and a large share of our commercial work is within half an hour of the office. That means quicker surveys, a team that knows the local planning and grid picture, and engineers who can be back on site quickly if you ever need them.

Every project is handled in house, from the first look at your bills through design, the network operator application, installation, commissioning and ongoing maintenance. You deal with one team throughout, not a chain of subcontractors.

Dumpton School is a good example of how a Dorset project comes together. Rising energy costs pushed the school to act, a carbon review recommended solar, grant funding made the numbers work, and the school chose DES after comparing four installers. The system was designed, approved and commissioned in around three months. See all our commercial case studies.

What we install for Dorset businesses

Commercial solar PV

Rooftop systems on industrial units, offices, barns, schools and retail buildings, plus ground-mounted arrays where you have the land. We design around your roof structure, shading and, most importantly, when your business actually uses electricity, so as much of the generation as possible is used on site. More on our commercial solar PV service.

Battery storage

Batteries let you keep daytime solar for later, cut peak-time imports and, with the right design, keep critical circuits running during a power cut. See commercial battery storage.

EV charging

Workplace and customer charge points, ideally running on your own solar. See commercial EV charging.

Maintenance and repairs

Inspections, cleaning, monitoring and fault finding for commercial systems, including ones we did not install. See commercial solar maintenance and operations and maintenance.

Sectors we work with across Dorset

Dorset’s economy is a mix of manufacturing, farming, tourism and public services, and the right system looks different for each. Our sector guides:

How a commercial solar project works with DES

1. Free site surveyWe look at your roof or land, your electrical intake and your usage data, ideally a year of half-hourly readings if you have them.
2. Design and proposalA system sized to your daytime demand, with expected generation, self-consumption and a clear written quote.
3. Grid and planningWe handle the network operator application (usually G99 for commercial systems) and check whether planning permission is needed.
4. Installation and handoverOur own team installs, tests and commissions the system, sets up monitoring and provides the MCS and electrical paperwork.

Paying for commercial solar

Most of our commercial clients buy their system outright, and many find it pays for itself well within its working life because so much of the electricity is used on site during the working day. Other routes include business finance and, for larger sites, a power purchase agreement where you pay for the electricity rather than the equipment. Solar equipment may also qualify for capital allowances, so it is worth speaking to your accountant. Some Dorset schools, charities and community buildings have used grant funding in the past, and we can tell you what is currently available when we survey.

Commercial solar questions from Dorset businesses

Which parts of Dorset do you cover?

All of it. We are based near Wimborne and regularly work in Poole, Bournemouth, Christchurch, Ferndown, Verwood, Blandford, Dorchester, Weymouth, Portland, Bridport, Sherborne, Shaftesbury, Gillingham and the surrounding rural areas.

How big a system do we need?

It depends on how much electricity you use during the day, your roof or land space, and your grid connection. We size systems around your actual usage rather than simply filling the roof, because electricity used on site is worth far more to a business than electricity exported.

Do we need planning permission?

Many rooftop commercial systems fall under permitted development, but there are limits, and listed buildings, conservation areas, larger ground mounts and some coastal locations need more care. We check this as part of the design and handle any application with you.

How long does it take?

Our Dorset projects have typically taken one to four months from design to commissioning, depending on size and how long the network operator takes to approve the connection. The installation itself is usually a matter of days to a few weeks, planned around your operations.

Can you add a battery or EV chargers later?

Yes. We design with future additions in mind, so batteries and charge points can be added without redoing the solar.
