A Solar PV System that could give you up to 22% IRR*?

Switching energy supplier every year won’t beat that!

*We’ve given a quote this year, November 2022, where the PV system would provide a 22% yearly payback, and would pay for itself in 5 years.

Solar PV

Systems to fit your needs, your budget and your space.

Electricity prices are rising sharply, to an average domestic tariff price of 35p/unit. We design all solar PV systems to closely match your energy consumption, rather than export income (currently 3-5p unit). We size your solar PV system to ensure you will use as much power generated as possible.

*A 4kW PV system will typically generate between 3,400 and 3,800 kWh per year in the South Wales region. Over a 20 year period that’s between 68,000 to 75,000 kWh of electricity supplied by you. At a typical cost of £4,700 (currently no VAT until 2027), that equates to a unit price of less than 7.5p per kWh if you use all the power generated.


We carry out a 2 hour site survey along with a bespoke PV report, to determine if a Solar PV System would make sense for you.


We provide a detailed assessment report of generation and cost savings, and suggest other energy efficiency measures.


We give you a professional service based on years of experience, and provide an installation quality guarantee for two years at no additional cost.

“The Gwent Energy team have been thorough and very professional; I experienced excellent satisfaction from initial design of the system, through installation, to online support. I would have no hesitation in recommending Gwent Energy to anyone considering installation of a renewable energy system.
