Solaire thermique
Solar thermal collectors convert solar radiation directly into useful heat. They can be used for domestic hot water, space-heating support and other thermal loads.
PV-T
Photovoltaic-thermal (PV-T) technology combines electrical generation with thermal recovery. The thermal side can improve overall energy utilisation when there is a suitable heat demand and hydraulic design.
Choisir la technologie
The right technology depends on the project load profile, roof area, electrical demand, hot-water demand, storage strategy, climate and economics. A project-specific assessment is more useful than comparing headline efficiency numbers alone.
