Solar designs we've done in Castle Donington
These are real 3D roof designs from Spectrum quotes in Castle Donington, for homes and businesses. Every solar quote we send includes one for your own roof, showing where each panel goes.

Commercial Solar Castle Donington
Castle Donington is surrounded by large distribution sites. The former power station site is now the East Midlands Distribution Centre, off the A50 near junction 24A of the M1, where Marks and Spencer is the main occupier, and SEGRO's East Midlands Gateway is just to the east by Kegworth. Large warehouse and industrial roofs with steady daytime loads are well suited to commercial solar.
We also cover smaller businesses in the village and on the business parks around the airport, such as Stud Brook and Willow Farm. We size each system to the roof and to what the grid connection can take, and payback for businesses is typically around 4 to 8 years, depending on how much of the power you use yourself.
We handle the design, the grid application and maintenance afterwards, and businesses can claim capital allowances on the system cost (your accountant can confirm the relief). Read our guide to solar for businesses or see our case studies.
Residential Solar Castle Donington: Landlords and Developers
Castle Donington grew from 6,416 people in 2011 to 7,346 in 2021, and the Park Lane development was approved in 2015 for 895 homes, with building on the Charters Gate estate from 2018. Developers can use solar towards Part L compliance, and landlords can use it to lift EPC ratings.
We run portfolio jobs as one project, with phased installs and Part P certification. Read about solar for property portfolios or new-build developments.
Domestic Solar Panels Castle Donington: Homeowners
For homes in Castle Donington and the surrounding villages, solar cuts the electricity you buy, and a battery lets you use more of what the panels generate in the evening.
On the newer estates around Park Lane, we check whether your home is connected to NGED or to an independent network operator before we apply for the grid connection.
Domestic solar and battery installs are zero-rated for VAT, currently due to run until 31 March 2027 (the rate is set by when the job is installed and invoiced), and you are paid for exported power through the Smart Export Guarantee. We can add battery storage, EV charging and, if you want it, Home Assistant with Predbat as an optional extra.
What Matters for Solar in Castle Donington
Planning and Conservation
North West Leicestershire District Council is the planning authority for Castle Donington, and the village has its own parish council. Most home solar is permitted development, but the rules are different for listed buildings and can be for homes in a conservation area. The village's conservation area, first designated in 1972, was split into two in 2023, Castle Donington and Castle Donington (High Street), and Cavendish Bridge has its own. We check your address before we design.
Grid Connection
Castle Donington is within National Grid Electricity Distribution's East Midlands area. Smaller systems go in as a G98 notification and larger ones need G99 approval. Some new-build estates are connected through an independent network operator instead, so we check your MPAN before we apply.
Homes and Roofs
The historic centre has timber-framed houses, including the Key House on the High Street, dated 1636, alongside the 13th-century church of St Edward King and Martyr and the earthworks of the 12th-century castle. Newer homes include the Park Lane development, and Donington Hall, built around 1790, is being converted into a hotel.

Kit, Warranties and Guarantees
We fit tier-one panels (30-year performance warranty on the models we use most), Solis hybrid inverters supplied with a 10-year warranty, and Fogstar batteries on most homes or Pylontech on larger commercial systems, and we can usually supply another make if you prefer; see our solar technology.
Every installation carries our 5-year workmanship guarantee and a QANW insurance-backed guarantee on top of the manufacturers' warranties, and Spectrum is insured through QBE UK Limited (£10M employers' liability, £5M public and products liability, £1M professional indemnity).
Accredited and Insured
How It Works
We start with a satellite view of your roof and your electricity use, then send an all-inclusive design and quote (subject to site survey), normally within 48 hours. A site survey confirms the details, we handle the grid paperwork, and most homes are installed in 1 to 2 days, around 4 to 6 weeks from first enquiry; our installation guide explains each step.
What Our Customers Say
★★★★★
"Brilliant company to deal with. From the initial chat about my requirements to installation, I can't fault one thing. I found Solar somewhat a minefield with some people trying to bamboozle me with information but Spectrum helped explain it in simple terms. The installation was faultless and they even called me 2 days later just to check everything was running OK. 10/10 team. Would definitely recommend."
