Commercial solar installations can provide significant long-term savings while demonstrating a commitment to environmental responsibility and energy efficiency.
Yes. Solar panels work from daylight, not just direct sunshine, so they still generate electricity on cloudy days. Output is higher in spring and summer, but panels continue producing energy throughout the year.
Yes. Solar can be installed on residential properties, apartment blocks, offices, warehouses, schools, care homes, and other commercial buildings, subject to roof space, electrical capacity, and site suitability.
Savings depend on the size of the system, electricity usage, energy prices, and how much of the generated power is used on site. Commercial sites often see strong savings because they use electricity during daytime hours when solar generation is highest.
Battery storage is optional. For homes, batteries help store daytime solar energy for use in the evening. For commercial sites, batteries can help reduce peak demand, increase self-consumption, and support smarter energy management.
Most residential solar installations take around 1–2 days once scaffolding and materials are ready. Commercial installations vary depending on system size, roof access, electrical works, and health and safety requirements.
Most domestic solar installations fall under permitted development. Commercial solar may also be permitted in many cases, but listed buildings, conservation areas, flat roofs, and larger systems may need additional checks or approval.
Most standard solar systems shut down during a power cut for safety reasons. Backup power requires a suitable battery system and backup setup designed specifically for that purpose.
Smaller systems usually require standard notification to the Distribution Network Operator. Larger residential or commercial systems may need DNO approval before installation, especially where export levels are higher.
Solar panels require very little maintenance. We recommend periodic checks to confirm the system is performing correctly, especially for commercial sites where monitoring and maintenance can help protect long-term savings.
REX installs residential and commercial solar PV systems with a focus on clean workmanship, compliant design, reliable equipment, and practical advice. We can help with solar panels, battery storage, system design, installation, and ongoing support.
