Gwalia Healthcare –

Solar PV Installation

Sector: Industrial, Manufacturing & Logistics / Renewables
Service: Solar Panel System Design & Installation
Client: Gwalia Healthcare
Completion: June 2024

About this Project

Gwalia Healthcare, a leading manufacturer in South Wales, has transformed its energy strategy by switching to on-site solar generation. Evans Electrical was appointed to design and install a high-performance solar PV system, tailored to deliver immediate energy savings and long-term sustainability benefits.

In the first year alone, the new solar system generated over £114,000 in savings. Projected across 25 years, Gwalia Healthcare is expected to benefit from more than £4.1 million in accumulated cash flow. With a payback period of just 3.6 years and an internal rate of return (IRR) of 31.31%, this installation represents a strong financial investment in addition to being an environmentally responsible move.

Key Outcomes

Over £114,000 saved in energy costs in year one
£4.1 million projected total cash flow over 25 years
3.6-year payback period
31.31% internal rate of return (IRR)
Energy cost of just £0.0501 per kWh, below market rate
249,160 kg CO₂ offset annually – equivalent to planting 11,325 trees per year
Total lifetime carbon savings equal to approx. 283,136 trees
24.4% self-sufficiency from on-site generation
93.9% of generated energy used on-site

Project Highlights

**Tailored Design:** The system was custom-designed to suit Gwalia Healthcare’s multi-elevation roof space, maximising solar yield.

**High Efficiency:** With a performance ratio of 94.52%, the system delivers consistent energy generation throughout the year.

**Grid Independence:** Significant on-site consumption and self-sufficiency reduce exposure to volatile energy markets.

**Environmental Impact:** CO₂ offset equivalent to planting over 11,000 trees each year reinforces Gwalia’s sustainability leadership.

**Certified Installation:** Fully compliant with MCS standards, ensuring high-quality components and workmanship.

Outcome

Evans Electrical’s expert installation of the solar PV system has enabled Gwalia Healthcare to reduce energy costs, stabilise long-term energy expenses, and significantly lower its environmental impact. This project exemplifies the economic and operational advantages of renewable energy adoption in the manufacturing sector.
