What pre-sizing and pricing ratio could be taken into account for a collective project?
For your projects on a collective building, we let you see the ratio below for a pre-sizing, estimated productivity and pre-cost of your installation, regarding what is your project.
If you are currently sizing your installation we invite you to contact us directly for a more detailed study through the form on our webpage dedicated to professionals.
These ratios will allow you to have estimated data for your pre-study, but can not replace the quote from a competent installer. These ratios are not meant for a residential individual project.
Ratios:
Estimated sizing (panel’s surface) | Water to water heat pump | Pool heating | Hot Sanitary Water |
m² of DualSun panels | 3 m²/kW of heat output of heat pump | 1 m² /m² pool area | 2 m²/ accomodation |
For an individual pool heating project, we let you see the ratio to take here.
Estimated annual productivity (kWh/m²/year) |
| Water to water heat pump | Pool heating | Hot Sanitary Water |
Area H1 (Paris) | Thermal | 300 | 240 | 200 |
PV | 200 | 195 | 190 | |
Area H2 (Lyon) | Thermal | 400 | 300 | 240 |
PV | 220 | 215 | 210 | |
Area H3 (Marseille) | Thermal | 480 | 400 | 300 |
PV | 280 | 275 | 270 |
The estimated annual production will be this annual productivity x installation size
Investment (turnkey solar package in €HT) | 50 m² | 300 m² | 1000 m² | 2000 m² |
CAPEX (Estimated supply and installation price) | 850 €/m² | 650 €/m² | 600 €/m² | 550 €/m�� |
OPEX (annual P2 Maintenance) | 7 €/m².an | 5 €/m².an | 4 €/m².an | 3 €/m².an |
P2 : Labour for operation, maintenance
