Discover The Solar Heat Pump

What is a solar heat pump for cooling and heating and how does it work?

A solar heat pump for cooling and heating combines the efficiency of a heat pump with the power of solar energy to cool and heat your home. While a traditional heat pump transfers heat from the outside air to your home in winter and releases it in summer, a solar heat pump goes a step further by using solar panels to power the system. This reduces your reliance on the grid and cuts down on energy costs.

Ecosolaris’ heat pump can operate in 3 different modes: hybrid (DC-AC), solar-only (DC only), or with a battery backup.

1- Hybrid mode: The system is uniquely engineered to use DC power (produced by solar panels) as its main energy source, and seamlessly draws from the grid (AC power) when solar power is unavailable or insufficient. This hybrid DC-AC capability ensures that your home stays comfortable day and night, all year long. 

2- Solar-only mode: Another option is for the heat pump to be powered solely by DC power from solar panels. The heat pump won’t be connected to the grid and will not function at night or when there’s no sun.

3- Battery backup: In the final scenario, the heat pump offers complete grid independence and runs on battery power, which is charged by solar panels, ensuring continuous cooling or heating—even at night or during power outages—without any reliance on the grid.

What is the difference between a ducted and ductless mini-split?
