Rey Solar Project

Over the past decade, the cost of solar energy has decreased significantly, making it one of the most competitive sources of new electricity generation. Thanks to Spain’s abundant solar resources and continued advances in efficiency, construction, and grid integration, large-scale solar projects like Rey Solar are increasingly cost-effective compared to conventional energy sources.

Unlike fossil fuels, solar energy has no fuel costs and relatively low operating expenses, which helps provide more stable and predictable electricity prices over the long term. Projects like Rey Solar also generate local economic value by creating jobs during both construction and operational phases, while supporting skills development and training in the region.

While manufacturing and installing solar panels requires energy and materials, the overall environmental impact is very low compared to conventional energy sources. Rey Solar, for example, will avoid approximately 184,000 tonnes of CO₂ emissions annually, equivalent to removing around 25,000 combustion-engine cars from the road, making a significant contribution to tackling climate change. In addition, the project incorporates specific biodiversity protection measures, including lesser kestrel conservation programs, avifauna monitoring, and sustainable agricultural practices that support local ecosystems.

Rey Solar not only generates clean energy but also delivers significant social value to the local community. Through its Community Care program, Recurrent Energy signed a collaboration agreement with Carmona Town Council to fund improvements to local infrastructure, services, and public spaces. The project has supported 14 educational centres — including schools, adult education centres, and facilities for people with disabilities — by donating and installing equipment to improve learning environments.

Additionally, Rey Solar promotes local employment by prioritising local hiring and collaborating with training institutions to enhance long-term employability in the area, creating direct and indirect jobs during both construction and operational phases.

Through its Community Care program, Recurrent Energy signed a collaboration agreement with Carmona Town Council to fund improvements to local infrastructure and public spaces. The project contributed to the improvement of 14 educational centres — including nine schools, two institutions for people with disabilities, and three adult learning institutes — through the donation and installation of equipment designed to enrich learning environments.

Environmental stewardship is a core pillar of the Rey Solar project. The facility incorporates a flagship lesser kestrel conservation programme that has already led to the successful hatching of chicks on site. Additional biodiversity measures include continuous avifauna monitoring, the creation of habitats through organic farming practices, and sustainable agricultural initiatives that support and enhance local ecosystems.

Rey Solar features Canadian Solar’s TopBiHiKu7 N-type bifacial TOPCon (Tunnel Oxide Passivated Contact) solar modules — one of the most advanced panel technologies currently available. TOPCon modules achieve higher efficiency by minimizing energy loss at the cell surface, while the bifacial design captures sunlight from both sides of the panel, boosting overall energy yield.

Rey Solar is operated and maintained by Recurrent Energy Power Services, one of the world’s leading O&M providers. The facility benefits from round-the-clock, 24/7 monitoring through Recurrent Energy’s proprietary in-house software, which analyses performance data on a daily basis to detect anomalies, minimise downtime, and maximise energy generation.

A dedicated team of specialists ensures that preventive maintenance programmes are carried out proactively, and that any on-site intervention is executed rapidly. This approach has consistently delivered plant availability above 99% across Recurrent Energy’s global portfolio.
