Solar is the longest, messiest sales cycle in home services. A homeowner clicks an ad on Tuesday. Six months later, if everything goes right, panels are on the roof. Between those two moments sit 15 to 20 distinct handoffs: qualification, site survey, design, proposal, financing, contract, permitting, utility interconnection, install, inspection, PTO. Miss one handoff and the deal dies or the install date slips by weeks.
This post walks the workflow we see working for solar installers doing between $5M and $50M a year.
Why Solar Breaks Generic CRMs
Most installers start on a generic CRM. It works until volume picks up. A generic CRM tracks a deal stage but does not track the 20+ parallel tasks that have to clear for an install to happen. Design is waiting on the site survey. Permit is waiting on HOA approval. Install is waiting on the utility.
A solar workflow that actually runs has to model parallel tasks, not linear stages. The deal record is the spine. Attached to it are task threads for sales, engineering, permitting, finance, and operations. Each thread moves on its own clock. The deal only progresses when every thread clears.
The Qualification Workflow Saves the Most Money
Every unqualified site survey costs the installer $200 to $400 in truck roll, design time, and sales rep hours. Installers with no qualification workflow run site surveys on every lead and bleed margin.
A clean qualification workflow runs before any human touches the lead: pull the property address and check roof suitability from satellite imagery, pull historical utility usage if the homeowner provides a bill, check HOA and shading conditions, verify the homeowner is not a renter and the roof is not due for replacement in the next 5 years, and auto-disqualify if the system size would be under 4kW.
Only leads that clear all of this get a site survey scheduled. Installers who add this filter typically drop their site survey cost by 40 to 60 percent and lift their close rate on surveyed leads from 15 percent to over 30 percent.
Same-Day Design and Proposal
The site surveyor is on the roof taking measurements. That data needs to flow directly into the design tool. By the time the surveyor is back in the truck, design should be 80 percent complete.
Same-day proposal delivery is the single highest-impact lever on close rate in solar. Installers running 72+ hour proposal delays close at roughly 15 percent. Installers delivering same-day close at 28 to 35 percent.
Financing Is Where Most Deals Die
The proposal looks great. The homeowner wants to move forward. Then financing stalls. The fix is treating the application as a live task, not an email attachment. 48-hour deadline. Auto-call if not started. Auto-requeue to a secondary lender if declined. Contract auto-generates on approval.
The gain is closing the financing-to-contract gap from 14 days down to 3 to 5 days.
Permitting and Interconnection in Parallel
After contract, the hardest part is just starting. Permits and interconnection can take 30 to 90 days each and stall an install indefinitely.
Run them in parallel, not sequentially. Permit application fires within 48 hours of contract signature. Status checks happen automatically every 3 to 5 days. Utility interconnection application fires in parallel. Homeowner gets a weekly status update so they do not ghost on install day.
Installers who run permitting and interconnection in parallel drop their average contract-to-install time from 90 days to 55 to 65 days. That is real cash flow improvement.
Install Day and PTO
Parts list auto-generated from design. Crew assignment based on certifications and geography. Day-before confirmation with crew photos. Install checklist photo-verified at each step. Inspection scheduled before crew leaves. PTO application files same-day as passed inspection.
After PTO: first month of production reports, review request, referral offer. Solar referral rates from happy customers run 15 to 25 percent of new business when the post-install workflow is built, and close to zero when it is not.
