If you’re thinking about installing solar, you might be surprised to learn that winter is one of the best times to make the move. While many people associate solar panels with hot summer days, installing a system in winter has many advantages.
Do solar panels work in the cold?
Yes, solar panels work just fine during cold weather. This is because they don’t convert heat into electricity, they convert sunlight. So even on cold winter days, solar panels will continue to generate power during daylight hours. Cooler temperatures can actually help panels operate more efficiently. The optimal temperature for most solar panels is between 15°C and 35°C.
Do solar panels work when it’s cloudy?
Yes, solar panels can still produce energy on cloudy days, though their output will be much less compared to sunny days. Solar panels work best in direct sunlight, but they still generate power from indirect sunlight. This means that even on cloudy or rainy days, you can still expect your system to produce some electricity.
Benefits of Installing Solar in Winter
Beat the Summer Rush
Summer is typically the busiest time of year for solar companies. This is because many homeowners delay installing solar until spring or summer, assuming that’s the most effective time. However, installing during the off-season can work to your advantage. During this seasonal lull, solar installers have greater availability. This means you’re more likely to have a quicker turnaround from your initial quote to a completed system.
Prepare for Summer
When summer arrives, temperatures rise and electricity bills spike as a result. Many people then rush to install solar to offset their summer energy use. This often leads to longer wait times for installations, with some people having to wait up to four to six weeks. Solar installations also involve grid connection and council permissions, which also take time to approve. If these delays all take place in summer, you’ll miss out on prime solar saving days. By installing in winter, you can have your system up and running before peak demand. So as soon as summer hits, you can take full advantage of the longer daylight hours and higher sun exposure.
Take Advantage of the Current Solar Incentives & Rebates
The Federal and State Governments offer various benefits and incentives for installing solar energy systems. Most of these solar incentives are available all year round. However, in 2025, they introduced a new WA Battery Scheme and a federal Cheaper Home Batteries Program. Applications for both of these rebates are now open from 1 July 2025. There is a limited number available, so if you wait until summer to install your solar battery system, it may be too late.
