PV Slate
PV Slate combines traditional slate aesthetics with solar energy generation. Each unit replaces four natural slates while providing 28W of power output. Backed by a 25-year warranty, these lightweight yet durable units withstand UK weather conditions. Compatible with blue-grey natural slates, they offer seamless integration for heritage buildings and modern properties alike.
Infinity Solar Roof
The Infinity Solar Roof delivers uninterrupted solar coverage from ridge to gutter. Constructed with glass and powder-coated aluminium, this system achieves EXT.S.AA fire rating. Custom-sized panels accommodate complex roof geometries while maintaining waterproof integrity. Ideal for new builds and full roof replacements across residential and commercial properties.
Integrated Solar Panels
Our integrated solar panels replace conventional roofing materials while maintaining structural integrity. Using marine-grade aluminium and stainless steel fixings, the system eliminates debris accumulation risks. Suitable for pitches between 10-45 degrees, it offers ventilation to prevent efficiency losses. Available in custom sizes for optimal roof coverage.
Commercial Solar Projects
We manage complex commercial solar installations including industrial buildings and social housing retrofits. Our team handles projects from initial design through to completion, ensuring compliance with safety and quality standards. Recent projects include 146kW flat roof systems and public sector installations with integrated monitoring solutions.
Marine Solar Applications
Specialised solar solutions designed for marine environments utilise corrosion-resistant materials. Systems incorporate waterproof mounting frameworks and durable cabling to withstand saltwater exposure. Ideal for boats, marinas, and coastal installations requiring reliable renewable energy generation in challenging conditions.
