seful winter heat is collected from the solar array by adding low-cost ducting and fans. Air cools PV cells, and recovers waste heat that is used for space heating to improve comfort.
Combined Heat and Power

Warmth stored in the building interior can persist, delaying the need to use additional heating.
The array cools down on summer nights and the same system can be used for cooling air.

ADDED VALUE from thermal energy capture. Warm air to heat rooms in winter with summer options too.
In summer heat can be exhausted through roof vents or used to improve the efficiency of a hot water heat pump system. Heat pump water heaters produce cold air as a by-product that could be used in a kitchen pantry for example.
Alternately the air ducting from the roof space can work in reverse in summer as it will extract warm air from below by a chimney effect - even without a fan! At night the system can produce cool air brought down from the PV roof.

The PVFASTROOF* concept

The PVFASTROOF* concept suits projects where multiple roofs are to be installed with PV. Pre-assembly can speed up installation with less time on roofs for workers than in a secure factory setting.

The preassembled and wired solar tile array with flashings and venting is lifted into position on roof trusses and secured. Normal roofing than proceeds around the PV array.
