GB-Derby: General Construction Trades - Solar PV Installation

We are seeking a Service Provider to install solar PV panels onto the roofs of dwellings. These may be existing roofs, recently replaced roofs (under our re-roofing programme) or new roofs (as part of our new building programme). They may be on a variety of different property types and roof pitches. Each roof will be fully completed prior to the Service Provider undertaking their work. It is intended that the systems shall have a lifespan of not less than 25 years and should be designed and installed accordingly.
