Is combining air conditioning with solar panels a smart move?

A fixed air conditioner is actually an air-to-air heat pump. In summer, the unit draws in warm air from outside and cools it down. In winter, it works in reverse.

To power your air conditioning, your solar panels can provide the solution. If you turn on your air conditioning when the sun is shining, you can consume the energy you’re generating and shrink your energy bill. This is an especially good idea in summer, when the sun is out for longer and you more often need your air conditioning to keep your home cool.

Of course, it’s not very convenient if you always have to keep an eye on when you’re generating enough power to run your air conditioner, which is where smart controls such as automatic on/off switches and schedules can come in handy.  

• Efficient energy consumption: the sunniest times of the day are when your home heats up fastest, and that’s when your solar panels provide the most energy which you can immediately use for cooling.
• Lower energy costs: with the right combination, you can save a lot of money per year.
• Cool in summer, warm in winter: air conditioning ensures a pleasant temperature in your home all year round.
• Fewer CO₂ emissions: by using the energy you produce, you draw less energy from the grid.

Don’t forget: solar energy production is lower in the morning and evening. A home battery can help you use your generated power later in the day and lets you avoid having to draw power from the grid.  

If you want your air conditioner and solar panels to work well together, here are a few simple tips:

• Use your air conditioning during the sunniest times of the day: usually between 12 p.m. and 4 p.m.
• Set the right temperature: no lower than 23°C in summer and no higher than 21°C in winter.
• Close your windows and doors when your air conditioning is on so hot or cold air can’t escape.
• Consider installing a home battery so that you can continue to use your generated energy in the evening.

Combining a fixed air conditioner with solar panels is an excellent idea. The installation isn’t technically complex and can be financially beneficial, especially if you match your consumption to how much the sun is shining.

You’ll also keep your home cool in summer and warm in winter without having to worry about your energy bills.
