Manufacturers datasheet

The Redland SRT80 PV tile system has been designed to provide a “universal” PV roofing solution - enabling integration with a wide range of tiles, slates and other roofing materials.
Although it uses a larger format PV module than the SRT40, the SRT80 system shares many similar features - mounting is direct onto standard tiling battens and it is a modular product, allowing flexibility in system design.
Like all Redland products, the SRT40 and SRT80 systems have been fully tested and proven under storm and driving rain conditions and carry the standard Redland 15 year weather-tightness guarantee.
