Outdoor & UVUpdated 18 Sept 2026

Which enclosure is best for solar equipment exposed to UV outdoors?

Short answer

For solar equipment installed outdoors, we recommend our GEOS industrial and outdoor enclosures, which are crafted from high-grade polycarbonate, a material known for its excellent UV-resistant properties. Prolonged UV exposure can degrade the material of an enclosure, compromising its integrity and the safety of the components inside. The GEOS range comes with either an IP66 or IP67 ingress protection rating, withstands a temperature range of -40°C to +80°C, and incorporates BEL Air ventilation to prevent condensation building up inside while maintaining the IP rating. A secure locking mechanism and flexible mounting options and internal configurations accommodate circuit breakers, grounding equipment and other components.

For a solar project with components exposed to direct sunlight, we strongly recommend our GEOS industrial and outdoor enclosures: https://www.spelsberg.com/geos-industrial-and-outdoor-enclosures/. These enclosures are crafted from high-grade polycarbonate, a material known for its excellent UV-resistant properties.

Understanding the impact of UV radiation on an enclosure is crucial, especially when it is housing sensitive electrical components for a solar project. Prolonged UV exposure can degrade the material of the enclosure, compromising its integrity and the safety of the components inside. Safeguarding the components within our enclosures is of paramount importance to us.

The GEOS range comes with either an IP66 or IP67 ingress protection (IP) rating, offering a high level of protection against environmental conditions, which makes it particularly well suited to a solar project. The enclosures can withstand a temperature range of -40°C to +80°C and incorporate BEL Air ventilation to prevent the build-up of condensation within the enclosure, protecting the components inside while maintaining its IP rating.

These enclosures also feature a secure locking mechanism to prevent unauthorised access. They offer flexibility in terms of mounting options and internal configurations, allowing you to easily accommodate circuit breakers, grounding equipment and other components — all without compromising the enclosure’s robustness or its ability to protect against contaminants.

To tailor your enclosure further to your specific needs, our online configurator allows you to customise various aspects of the enclosure and ensure it meets all your project needs: https://www.spelsberg.co.uk/lp/configurato/
