If you’re a homeowner investing in solar panels—or considering it—you’ve probably wondered: can heat pumps run on solar power? The short answer is yes. In fact, heat pumps are one of the most solar-compatible HVAC systems available today. They operate entirely on electricity, making them a perfect match for solar-powered homes that want to minimize grid dependence, eliminate fossil fuels, and cut energy bills.
In this blog post, we’ll explore how heat pumps work with solar power, what makes them the best HVAC for solar homes, and how homeowners in places like Albuquerque can make the most of combining these two technologies.
What Is a Heat Pump and How Does It Work?
Before we talk about integration with solar, let’s quickly cover the basics. A heat pump is an all-in-one system that heats and cools your home using electricity and refrigerant—not fuel combustion. In summer, it works like an air conditioner by pulling heat out of your home. In winter, it runs in reverse, extracting heat from outdoor air (even when it’s cold) and transferring it inside.
Because heat pumps move heat instead of generating it, they can deliver up to 3x more energy than they consume. That’s a game-changer for energy efficiency—and a perfect setup for pairing with solar.
Yes, Heat Pumps Can Run on Solar Power
Here’s the good news: heat pumps are fully electric, so they can be powered by your home’s solar energy system. Whether you’re connected to the grid or using a battery-backed solar system, your heat pump can run cleanly and efficiently on sun-generated electricity.
Why Heat Pumps and Solar Are a Perfect Pair:
- Both are electric systems that support whole-home electrification
- Lower operating costs when powered by solar energy
- No fossil fuel dependence for heating or cooling
- Better energy ROI on your solar system investment
In other words, the more clean electricity your solar panels generate, the more free energy you have to power your HVAC system.
How Many Solar Panels Do You Need to Run a Heat Pump?
The exact number of panels depends on your system size and home energy usage, but here’s a general idea:
Average Home Scenario:
- Heat pump system usage: 2,000 – 6,000 kWh/year
- Standard solar panel output: ~300 – 350 watts per panel
- Estimated solar panels needed: 6 to 12 panels just for the heat pump
Most homeowners already size their solar array to cover total household energy usage, which often includes the HVAC system.
💡 Tip: If you’re building a new home or upgrading your energy systems, ask your solar installer and HVAC contractor to collaborate on system sizing for best results.
Best HVAC for Solar Homes: Why Heat Pumps Stand Out
If you’re aiming to reduce your carbon footprint or move toward net-zero energy living, heat pumps are the best HVAC system for solar homes. Here’s why:
1. They’re 100% Electric
Unlike gas furnaces or propane systems, heat pumps require no fossil fuels.
2. They’re Energy Efficient
Heat pumps can achieve SEER ratings above 20 and HSPF ratings of 10+, making them one of the most energy-efficient HVAC options available.
3. They Work Year-Round
One system handles both heating and cooling, so you only need to power and maintain one unit instead of two.
4. Ductless Options for Flexibility
Mini split systems can serve homes without ductwork or be installed zone-by-zone.
5. They’re Eligible for Rebates and Tax Credits
High-efficiency heat pumps qualify for federal tax credits (up to $2,000) and local utility rebates.
What About Battery Storage and Off-Grid Systems?
If your home is off-grid or relies on battery storage (like Tesla Powerwall or Enphase systems), you may be wondering: is a heat pump still practical?
The answer: Yes—if properly sized.
Modern cold-climate and variable-speed heat pumps use far less power than legacy systems. When paired with battery storage, they offer a reliable and clean heating solution.
You’ll want to:
- Choose high-efficiency models (look for ENERGY STAR and high HSPF)
- Consider zoned ductless systems to reduce load
- Use smart thermostats to optimize usage and avoid power drain
The Role of Smart Thermostats and System Optimization
To get the most from a solar + heat pump combo, consider integrating a smart thermostat that can:
- Adjust temperature based on solar production or battery state
- Reduce energy use during non-solar hours
- Pre-heat or pre-cool your home when solar energy is most abundant
Popular models like ecobee or Nest can be integrated into home automation systems or used independently to cut waste and improve control.
FAQs: Heat Pumps and Solar Power
1. Can I run my heat pump at night on solar?
Yes, if you have battery backup. Without a battery, your heat pump will pull power from the grid during non-sunlight hours.
2. Will my heat pump work during a power outage?
Only if your solar system is connected to a battery. Grid-tied systems without storage shut down during outages for safety.
3. Are ductless mini splits solar-compatible?
Absolutely. Mini splits are electric and highly efficient, making them ideal for solar-powered and off-grid homes.
4. Will a heat pump help me reach net-zero energy?
Yes—especially when paired with solar, energy-efficient insulation, and smart thermostats.
Case Study: Solar + Heat Pump in Albuquerque
A local homeowner in Cedar Crest, NM, switched from a propane furnace to a high-efficiency Mitsubishi mini split system after installing rooftop solar. With an 8.2kW solar array and a 10kWh battery, they now run their home—HVAC included—almost entirely on solar energy.
Result: Energy bills dropped to under $20/month. Comfort improved. And they eliminated all fossil fuels from their heating system.

Final Thoughts: Should You Power Your Heat Pump with Solar?
If you already have solar—or are planning to install it—then yes, a heat pump is one of the smartest, most future-proof HVAC choices you can make. It’s fully electric, energy-efficient, and designed to work in tandem with solar panels and smart home systems.
Whether you’re trying to eliminate fossil fuels, reduce your bills, or move toward off-grid independence, heat pumps and solar power go hand in hand.
