When it comes to installing solar panels, timing can make a big difference — not just for energy production, but also for cost savings, installation availability, and financial incentives. While solar power delivers long-term benefits no matter when it’s installed, the best time of year to make the switch may be earlier than you think.
Spring Into Action
Spring and early summer are often considered ideal times for solar panel installation. As the days grow longer, your system will capture more sunlight, leading to a faster return on investment. Installing in spring also ensures your system is up and running in time to maximize energy production during the sunniest months of the year. More sunlight means more electricity, which can significantly reduce or even eliminate your electric bill through summer and into early fall.
That said, late winter can also be a smart — and often overlooked — choice. Many homeowners wait until the weather warms up, but you might find it easier to schedule your solar energy system install during the off-season. You also might benefit from shorter wait times and quicker permit approvals. By the time peak sunshine arrives, your system is already installed and optimized for performance.
Incentives for Early Birds
Earlier is usually better when trying to qualify for federal and state incentives. Many solar tax credits or rebates are based on the calendar year or available funds. Installing earlier in the year ensures you can take full advantage of these programs before they expire or change. For example, some previous incentives in Washington state have relied on grants or legislative appropriations — once the funds run out, the program is no longer available until the following year or whenever renewed by the Legislature.
Get Your Energy Independence
Having said that, there are good incentive-driven reasons to install a system just before the end of a calendar year. The federal solar investment tax credit (ITC) allows you to deduct a percentage of your system’s cost from your taxes — but only if your system is installed by year-end. Getting your panels up and running during the Christmas season can deliver an extra special gift during tax season that you would have missed had you waited until the new year.
Climate Considerations
In Washington state, it’s especially important to factor in the local climate when planning a solar installation. Rainy, overcast winters in Western Washington can slow down installation timelines due to wet conditions and limited daylight. Additionally, in areas that experience snow — particularly in higher elevations or Eastern Washington — roof access can be more challenging during the winter months.
For most homeowners in the state, early spring is an ideal time to install solar panels, as the weather begins to dry out and crews can work more efficiently, ensuring your system is ready to capture the increasing sunlight of late spring and summer.
