When Is the Best Time to Get Solar Panels?

The best time to get solar panels depends on season, incentives, and your own timeline. There is no single “perfect” month, but a few principles can help you get the most savings and the smoothest process. Many homeowners aim for spring or early summer installation to capture peak sun in the first year and to align with incentive deadlines, while others prioritize securing the 30% federal tax credit before any future changes.

Seasonal considerations

Spring and fall often offer mild weather, which can make installation easier and more comfortable for crews. Summer is when production is highest in most of the U.S., so having the system on by late spring means you maximize your first year’s generation. Winter installations are possible in many climates; production will be lower initially but catches up over the year. Snow can temporarily reduce output but usually slides off tilted panels. The main takeaway: production is averaged over 12 months, so the exact installation month matters less than getting a good price and locking in incentives.

Incentive and policy timing

The federal Investment Tax Credit (ITC) was 30% for systems placed in service through 2032. If you have sufficient tax liability, claiming the credit in the year the system is commissioned is usually best. Some state rebates have application windows or funding caps—check your state energy office or utility for deadlines. Net metering rules can change; in regions where future changes might reduce the value of exports, going solar sooner can lock in current terms. Our solar incentives guide lists major programs.

Market and installer availability

Demand for solar often peaks in late winter and spring as people plan for summer. Booking a few months ahead can secure a slot and avoid rush premiums. Conversely, late fall or winter can sometimes mean installer availability and potential promotions. Get at least 2–3 quotes regardless of season. Price and equipment matter more than a single month’s production.

When to wait (briefly)

It can make sense to wait a few months if you are about to replace your roof—installing solar on a new roof avoids removing and reinstalling panels later. If you expect a major change in electricity use (e.g. buying an EV, adding a heat pump), you might size the system for that. Otherwise, delaying for a hypothetical future drop in panel prices often doesn’t outweigh lost savings and incentive risk. Use the HearthIQ calculator to see how your location and home size affect savings.

Bottom line: the best time to get solar is when you’re ready, your roof is suitable, and you’ve locked in incentives. For many, spring or early summer installation balances production, weather, and incentive timing—but fall and winter can work well too. Focus on system quality, price, and incentives rather than a single “perfect” month.
