What pre-sizing and pricing ratio could be taken into account for a collective project? – DualSun

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.
