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 €/m²
OPEX (annual P2 Maintenance)	7 €/m².an	5 €/m².an	4 €/m².an	3 €/m².an

 

P2 : Labour for operation, maintenance

• Cleaning and routine maintenance of installations
• Driving, monitoring, adjustment of different equipment
• Annual preventive maintenance
