About SunQuest
Sunquest AG, based in Balsthal, is a Swiss subcontractor for DC installations in photovoltaic construction. The company takes on the complete DC installation of solar systems: construction of the substructure, module mounting, cabling and installation of the inverter. In addition, SunQuest offers project management from design through to acceptance, project support with reporting, as well as additional services such as construction site camera documentation, drone footage, module cleaning with a cleaning robot and nano-coating of modules. Installation is carried out on flat roofs (membrane/gravel/substrate), pitched roofs with all common roofing types, on facades (building-integrated photovoltaics) and on open ground. Customers are solar installers, electricians, roofers and dealers from commercial, industrial, agricultural and residential construction. With over 40 permanently employed staff, 11+ project vehicles and 64+ drilling machines and special tools, SunQuest is ready to handle several projects at the same time; referenced projects extend up to a large-scale installation with 7440 kWp and 16070 modules in Villmergen-Wohlen.

Materials & Systems
Solar modules (PV modules)
Mounted on flat-roof, pitched-roof and facade installations, cabled and optionally coated.
Substructure (PV mounting systems)
Tested mounting systems, e.g. ZinCo AG for green roofs, guarantee lasting stability.
Nano-coating (Ceracoat PV Cleaning Technology)
Nanotechnology from Practical Trade GmbH provides lasting protection for modules against dirt and reduces cleaning effort.
