Q&A Do I want to run an air con with my solar system
 
If the weather conditions are very humid and hot during most of the year. If you use your air con almost non-stop during scorching summer days, you’ll need a solar system that can handle this amount of power. Sometimes, it is worth spending a little extra on a more efficient air con as this may be cheaper than buying a larger battery bank or solar system to power an inefficient air con.
Typically, you can expect to need a:
> 3kWh to 4.5kWh sized solar system for a small air con
> 6kWh to 7.5kWh sized solar system for a medium air con
> 10.5kWh or greater sized solar system for a large air con
