Modern systems for homes are usually fitted with batteries and since the panel price reduction during late 2024, homes are maximising their roof space with as many panels as possible.

We fit black panels as standard usually with an output of 440 watts per panel. We only fit Tier 1 panels with market leading warranties up to 25 years.

Commercial and business clients, depending on use, can go for standard systems maximising output or large systems with storage. We have fitted solar for a huge range of business types including caravan parks, restaurants, farms, construction, food processing - any business that consumes electricity can benefit from solar.

With Inverters and Batteries we recommend using the same manufacturer for both inverter and battery. Our standard equipment can be fitted inside or outside with batteries scalable up to 25kw.

DNO Compliance

DNO compliance - here at GMC depending on your system we take care of grid compliance.

G98 - if your system inverter is under 3.68kw (could have up to 5kw panels with this inverter) we simply notify the local DNO once we have installed your system and request an export MPAN number for you to apply for export payments.

G99 - if your system inverter produces more than 3.68 we need to apply for permission first. GMC do this on your behalf and secure permission before we begin the install. Depending on the system there can sometimes be a connection fee. We keep you up to date with this during the process.

A No Sales Approach

Here at GMC we operate a no sales approach. We provide either a pre-survey estimate using online tools or a site visit where an engineer will access your home suitability and look at your energy consumption to design the best option for you. With either option you have price and all the information to make a decision in your own time.

After care: we have been installing solar since 2010 and we are still available for clients should they need. Any problems in the future, missing documents we keep on file for you.

What Our Clients Say

Real reviews, verbatim, from Google

★★★★★

“We have used GM Craig last year to install Solar Panels on our roof. I found them most helpful and courteous and installed the system without any problems. Their workmen carried out the work with due diligence and in a tidy manner. Mr Neil Craig filled out all the paperwork for the feed in tariff and all I had to do was sign the documents. I can without hesitation recommend GM Craig for fitting Solar Panels.”

GMC Solar System Installation Examples

Barmoor Castle

Barmoor Castle in Northumberland asked GMC to help lower their running costs and look at possible options for them. After considering a few options, the best solution was a 50kw system split over 2 industrial buildings away from their customers.
