Solar Panels

MCS-certified solar PV and battery storage for homes and businesses.

Solar panels are a long-term investment, so it is worth having them designed and fitted properly. We provide end-to-end solar PV (photovoltaic) installations for homes and commercial premises across Powys, Mid Wales, Wales and England — from the initial survey and system design through to commissioning and the paperwork you need afterwards.

Why install solar PV?

  • Cut your electricity bills: generate your own power and reduce what you buy from the grid.
  • Get paid for surplus: export unused electricity and receive payments through the Smart Export Guarantee (SEG).
  • Store your own energy: add battery storage to use your daytime generation in the evening.
  • Lower your carbon footprint: generate clean electricity at home or on your premises.
  • Add value to your property: a well-installed solar and battery system is an attractive feature to buyers.

MCS certified and fully compliant

As an MCS Certified installer, our work meets recognised industry standards for performance and safety. MCS certification is also what makes you eligible for the Smart Export Guarantee and, where available, other government schemes.

We also handle the Distribution Network Operator (DNO) notification on your behalf. Whether your system falls under G98 (up to 3.68kW per phase) or requires prior approval under G99 (larger systems), we take care of the compliance from design through to commissioning.

Solar works well alongside home EV charging and general electrical work, and we can quote for all of it together.

Frequently asked questions

Do solar panels work in Wales?

Yes. Solar panels generate electricity from daylight, not direct sunshine, so they still produce power on cloudy days. Output is highest in summer, but a well-designed system generates useful electricity all year round.

What is the Smart Export Guarantee?

The Smart Export Guarantee (SEG) is a government-backed scheme that requires large energy suppliers to pay you for the surplus electricity your solar system exports to the grid. As an MCS certified installer we can provide the documentation you need to sign up.

Do you install battery storage?

Yes. Battery storage lets you store the electricity your panels generate during the day and use it in the evening, when you would otherwise be buying from the grid. We design solar and battery systems together.

Do you handle grid connection and paperwork?

Yes. We handle the Distribution Network Operator (DNO) notification on your behalf — G98 for systems up to 3.68kW per phase, or G99 where prior approval is required — and provide the MCS certificate for your records.

How much does a solar installation cost?

Cost depends on the size of the system, the roof, whether battery storage is included and how the panels are mounted. We survey the property and provide a clear, itemised quote before any work begins. Call 07525 182686 to arrange one.
