The solar slow season, and a marketing plan for the months the phone stops
Why solar demand swings, what to sell in the quiet months, a month-by-month plan, service and storage revenue, and how to keep crews busy without discounting.
Solar seasonality is not the same everywhere, which is why generic advice fails. In hot states the phone rings when summer bills land in July and August, and goes quiet from November through February. In the northeast and midwest the pattern inverts partially, with spring interest and a winter installation slowdown driven by snow and roof access. Everywhere, there is a lull tied to the end of a program year, and everywhere there is a February where the owner starts worrying.
What is consistent is the shape of the problem. You have crews on payroll, a pipeline that was built 60 days ago, and a marketing budget you are tempted to cut at exactly the moment cutting it is most expensive.
Map your own year before you plan it
Do not use the industry's average. Pull your own CRM and chart two lines by month for the last three years: leads created, and contracts signed. Then add a third, installs completed.
You will usually find that signed contracts lag leads by six to ten weeks and installs lag signatures by another six to fourteen. That lag is the whole planning problem. The quiet install month you are worried about in January was actually caused by the lead volume you did or did not generate in October.
Write the lag down. Everything below depends on it.
The rule that matters: advertise into the lag, not into the panic
If your installs go quiet in January and your total lag is roughly 14 weeks, the marketing that fills January happens in late September and October. By the time the calendar is empty, you are already too late to fix it with ads.
Most solar companies do the opposite. They spend heavily in the busy months when the phone is ringing anyway and cut spend in the quiet months when cost per lead is often at its lowest of the year. Competitors pull budget, auction pressure drops, and the installer who kept spending buys the same lead for less.
Hold your ad budget flat across the year at minimum. If you can, increase it 20% in the two months preceding your quiet install window.
What to sell in the quiet months
Panels are not the only product you own. Four revenue lines fill quiet weeks and almost every installer ignores them.
Service and repair on other companies' systems. The single biggest opportunity in this industry right now. A large number of homeowners have systems installed by companies that no longer exist, and no one to call when production drops or an inverter fails. Search demand for repair terms is low competition and cheap. Build the page, run a small ad campaign at $3 to $8 a click, and take the calls. A service customer becomes a storage customer and an expansion customer later.
Battery retrofits to your own installed base. You have a customer list of people who already trusted you with five figures and who are now watching utility rules change and outages make the news. A campaign to your own installed customers, by email, text and a Meta custom audience, costs almost nothing and converts far better than cold traffic. This is the highest-margin work available to you in a slow month.
Panel removal and reinstall for roofing. Every roofer in your county has customers with arrays in the way. Get on the referral list of the three biggest roofing companies near you. It is steady, scheduled, indoor-season friendly work.
Commercial and agricultural, if you are equipped. Different cycle, different decision maker, frequently busy when residential is quiet.
A month-by-month plan for a hot-climate market
Adjust the months if your peak is different, but keep the sequence.
Peak season, roughly June through September. The phone rings. Do not sit back. Two jobs: capture reviews from every install at permission to operate, because this is when your volume is highest, and get every unclosed proposal into the follow-up sequence. Reviews earned now decide next February's search visibility. Also film content now, while crews are working and the weather is good, and bank it for the winter.
Shoulder, October and November. This is your budget increase window. Push Google Ads and Meta hard. Launch the storage campaign here, because outage season and holiday power anxiety help you. Send the retrofit campaign to your installed base.
Quiet, December through February. Cost per click falls. Keep spending. Run the service and repair campaign at full weight. Publish content: the awkward-question pages from the AI search guide, city pages, project pages. This is the only time of year you will have hours to write them, and they pay you back for years. Back-ask old customers for reviews in batches of 20 a week.
Ramp, March through May. Utility rate changes are frequently announced in this window and program years turn over. If a real change applies in your market, cover it factually with a link to the utility's or agency's own announcement. Book the assessments now that become summer installs.
Things not to do in the slow season
Do not cut the ad budget. Covered above. It is the most common and most expensive mistake in this trade.
Do not discount to fill the calendar. A January discount trains your market to wait for January, and it wrecks the margin that funds the marketing that fills next January. If you must move price, change the package rather than the number: add monitoring, add a longer workmanship term, add a service visit.
Do not lay off the coordinator. They are the person running review asks and follow-up sequences, both of which are pure slow-season work with delayed payoff.
Do not fabricate a deadline. Countdown timers and invented incentive expiries are how the door-knocking sales organizations filled their slow months, and it is why homeowners in your county now distrust the whole industry. If a real deadline applies, state it accurately with a source. If it does not, sell on something else.
Fixed costs and a fixed floor
Set a marketing floor you will not go below regardless of the month. For a company doing eight installs a month at a five-figure average, that floor is usually a few thousand dollars a month across ads and the retainer for whoever manages them.
Then treat the review process, the follow-up sequence and the content publishing as free capacity you already own. None of them cost money. All of them work on a delay. That is why the slow season is where they get built.
The benchmark angle
Look at the benchmark report and notice that 17% of solar companies have no reviews and 13.1% have no website. Those companies are not going to fight you for search visibility next season. A quiet quarter spent building reviews, service pages and city pages moves you past a large part of the field permanently, and the field does not catch up because most of them are cutting spend and waiting for the phone.
Frequently asked
Should I run a seasonal promotion at all? A value-add is fine. Free monitoring for two years, a free service visit at year three, a critical-load panel included on storage jobs. A price cut is not.
What if my slow season is losing money on payroll? Look at service, roofing reinstalls and battery retrofits before you look at layoffs. Those three lines are labor-heavy, margin-decent and available immediately.
Is content really worth writing in January? Ask yourself what would have happened if you had written ten pages last January. The companies ranking in your county now wrote theirs two winters ago.
