As the world accelerates toward clean energy solutions, photovoltaic (PV) heat pumps are gaining popularity for their ability to combine solar power with high-efficiency heating and cooling. But many homeowners and developers ask a crucial question:
How does a photovoltaic heat pump connect to the power grid—and how does this benefit energy usage?

Understanding the Connection: Solar + Grid Hybrid

A photovoltaic heat pump works by connecting a solar photovoltaic (PV) panel system to an electric air-to-water or water-to-water heat pump. During daylight hours, the PV panels convert sunlight into electricity, which directly powers the heat pump to provide heating, cooling, or hot water.

However, to ensure 24/7 functionality—even when sunlight isn’t available—the system is also connected to the public power grid. This grid connection allows the heat pump to:

Automatically switch to grid electricity when solar energy is insufficient (e.g., at night or on cloudy days).
Feed excess solar power back to the grid (when permitted by local net metering policies), potentially earning credits.
Maximize energy use efficiency with hybrid solar-grid balance for seamless operation.

Smart Switching, Seamless Comfort

Thanks to intelligent control systems, Nulite’s photovoltaic heat pumps are equipped with automatic switching features that detect the availability of solar power and switch to grid power as needed—without interrupting system performance or indoor comfort.

This hybrid setup makes it possible to maximize solar usage while ensuring consistent heating and cooling, all year round.
