Do solar panels work on cloudy days?

Though the sky is often blue in Australia, we still get our fair share of cloudy days. If you’re wondering how this will impact your solar panels, then we’ve got the answers.

If you’re thinking about getting solar panels, little questions like this that will take on big importance. It’s important that you think about solar from all possible angles, and do everything that you can to ensure your power supply remains reliable and that your decision makes sense for your wallet.

Do solar panels work on cloudy days?

The short answer is yes, but as you would expect, they may not work at their peak capacity. However, assuming you have installed the right size of system for your typical usage the energy lost during cloud cover shouldn’t threaten your power supply. If your capacity ever does diminish to the extent that your panels are no longer producing the energy required to power your home, extra energy will be provided through the energy grid.

Grid connection

Most homes and businesses that opt for solar panels choose to remain connected to the Australian electricity grid. This not only means that you could make money from selling your excess energy back to the Australian grid, but it also means that if your own system has a shortfall you can make up the difference from the grid.

Home battery

Another option for solar panel owners is to get their own home battery. This idea received a lot of press earlier this year when Tesla and SolarCity CEO Elon Musk unveiled the Tesla Powerwall and several other energy companies revealed their own designs for home batteries. The battery stores the energy that your solar panels create for use at a later date.

Basically, the answer is yes – Solar panels do still work on cloudy days. The extent of cloud cover in most parts of Australia is not severe enough to prevent you from getting panels. Even if there is a period of several days of thick cloud, provided your system is grid connected, your power supply will continue as normal and with no interruption.
