Solar PV
Transforming Properties with Smart, Sustainable Solar Energy
We design and install high-performance solar PV systems for homes, farms, schools and businesses. Each system is built for long-term energy savings, maximum efficiency and dependable renewable power.
About Our Solar PV Service
RER Electrical & Solar Ltd have been delivering high-quality Solar PV installations since 2020. In that time, we have installed over 200 systems nationwide, covering a wide range of environments including domestic homes, commercial premises, agricultural buildings, and educational facilities. Our experience across these sectors allows us to provide tailored solutions that meet the specific energy demands of each type of client.
We are fully SEAI-registered for both domestic and non-domestic installations, as well as TAMS-approved, ensuring all works are carried out to the highest regulatory and technical standards. Our dedicated in-house PV technician oversees every project from initial design through to final commissioning, ensuring consistency, quality control, and professional workmanship.
Our approach focuses on collaboration with our clients. We take time to assess each property, understand energy usage patterns, and design a system that maximises generation potential and long-term savings. Whether it’s increasing energy independence, reducing operational costs, or improving sustainability, we ensure each system is optimised for performance and future-proofed where possible.
From design and installation to testing, certification, and aftercare, RER Electrical & Solar provide a comprehensive service that ensures every customer receives a reliable, efficient, and fully optimised Solar PV solution.
Ground-Mount Solar PV Systems
In addition to rooftop installations, RER Electrical & Solar Ltd specialises in the design and installation of ground-mount solar PV systems. These systems provide a flexible, scalable solution for larger energy demands and are ideal where roof space is limited or unavailable.
Ground-mount solar is suited to:
Domestic and commercial properties
Farms and agricultural land
Schools, campuses and community facilities
Open fields and large sites
Ground-mount solar systems enable larger arrays, optimal panel positioning and easier access for maintenance and future expansion. Each project begins with a detailed site assessment, allowing us to design a compliant, high-performance system tailored to your site, whether fixed-tilt or tracking. We also manage SEAI and TAMS supports, delivering a complete end-to-end service that provides long-term savings, sustainability and energy independence.
