Solar Thermal Collectors

19 products

Solar thermal collectors convert sunlight directly into heat for domestic hot water and heating support. Our range includes flat-plate collectors from Bosch and Viessmann for on-roof and in-roof installation, compatible with buffer tanks and existing heating systems.

Rule of thumb for residential: 1 kWp of installed capacity produces roughly 950–1,100 kWh per year in central Europe. An average household consumes 3,500–4,500 kWh/year — a 4–6 kWp system covers most demand. Add a battery for self-consumption beyond 70%.

Roof orientation: south-facing 30–35° tilt = optimal. East/west splits work too, with slightly lower yield but a flatter daily production curve (better for self-use).

Note: this collection lists PV modules (electricity). For solar thermal collectors (hot water/heating support), see our Bosch Solar 4000 TF and 5000 TF flat-plate collectors — different product type.

Installation

PV installation must be carried out by certified electricians — grid connection requires registration with the local DSO (in Germany: Marktstammdatenregister). Roof statics, mounting system, and inverter sizing should be checked by a qualified installer.
