How does a Solar Heat Pump Work? A Guide for Homeowners Introduction

As energy prices rise and sustainability becomes a greater priority for homeowners, solar technologies are quickly becoming the go-to solution for energy-efficient living. Among the most innovative systems available today is the solar-assisted heat pump—a hybrid solution that combines the power of the sun with the efficiency of a heat pump. If you're exploring options to cut heating costs and reduce your carbon footprint, this guide will walk you through how a solar heat pump works, its components, and why SolaX offers one of the most advanced systems on the market.


1. The Basics of Solar Heat Pump Technology

1.1 What is a Solar Heat Pump?

A solar heat pump integrates photovoltaic (PV) solar panels with an air source heat pump. It uses electricity generated from solar energy to power the heat pump, which then extracts heat from the ambient air and transfers it indoors for space heating or hot water. Unlike traditional systems, this combination greatly improves energy efficiency and reduces reliance on fossil fuels or grid electricity.


1.2 How Solar Energy Powers the System?

During daylight hours, solar panels convert sunlight into direct current (DC) electricity. This electricity is either used in real time to power the heat pump or stored (if a battery system is installed) for use later. Even on cloudy days, the PV system can generate enough electricity to keep the heat pump running efficiently. At night or during low solar output, the system can switch to grid power as a backup—making it a truly flexible solar pump for home use.


2. Key Components of a Solar Heat Pump System

2.1 Solar Panels

These are the cornerstone of the solar assisted heat pump systems. Installed on rooftops or open ground, solar panels capture sunlight and convert it into usable electrical energy. High-efficiency heat pump with solar panels is designed to optimize output even in low-light conditions.


2.2 Refrigerant Circuit

The refrigerant circuit absorbs heat from the outdoor air. A compressor then increases the temperature of the refrigerant, which is used to heat water or indoor air. The SolaX system uses R290 refrigerant, a natural, eco-friendly alternative with a global warming potential (GWP) of just 3.


2.3 Heat Exchanger

This component transfers the heat from the compressed refrigerant to either your home's water tank or heating system. SolaX designs the heat exchange process to happen entirely outside the home, ensuring no refrigerant ever enters the living space—a safer and cleaner solution.


2.4 Control Systems

Modern solar hybrid heat pump systems come with intelligent control units that manage energy usage, monitor performance, and switch between solar and grid power as needed. With SolaXCloud, homeowners can access real-time data via a mobile app for ultimate convenience.


3. Working Process of a Solar Powered Heat Pump System

Here's a simplified version of how the heat pump solar powered system operates:

  • Solar panels generate electricity from sunlight.

  • That electricity powers the heat pump, which extracts heat from the air outside.

  • The refrigerant absorbs and compresses this heat to a higher temperature.

  • A heat exchanger transfers the thermal energy into your home's heating or hot water system.

  • The control unit optimizes energy usage, switching between solar and grid electricity when necessary.

  • This seamless integration of solar and thermal energy allows for consistent performance with minimal environmental impact.
