SunPath Solar Case Study – Upper Route Planner Home Customer Stories SunPath Solar SunPath Solar Cut Project Timelines by 30% with Geographic Route Optimization A Phoenix solar installation company managing 8 field crews and 15-25 daily site visits eliminated 20 minutes of average drive time between appointments, compressed project timelines from 8-10 weeks to 5-7 weeks, and resolved warranty disputes using timestamped photo documentation. In Conversation with Kevin Park, Operations Manager, SunPath Solar Key Results +2 Extra site visits per day 57% Reduction in average drive time 30% Shorter project timelines 18% Revenue increase per crew The Challenge SunPath Solar’s scheduling system was built for salespeople, not field operations. The company used Salesforce CRM to manage its pipeline and Google Calendar to schedule site visits. When a homeowner signed a contract, the project coordinator created calendar events for each phase: initial survey, engineering assessment, installation (typically 1-2 days), and final inspection. Each event was assigned to a crew based on availability, with no consideration of location. The result was a field operation where geography was an afterthought. Kevin Park had watched the problem grow for two years. On a typical Tuesday, the survey crew might start in Mesa, drive 40 minutes to Gilbert for their second appointment, then 35 minutes to Scottsdale for the third. Three appointments consumed nearly the entire morning, with more time spent driving than surveying. The installation crews had it even worse. A full-day installation in Chandler followed by a next-day install in north Phoenix meant the crew drove over an hour before starting work. 45+ minutes of average drive time between sites: Kevin tracked crew travel for one week and found the average drive between appointments was 45 minutes. For a survey crew handling 4 to 5 sites per day, that meant nearly 3 hours of driving against 2.5 hours of actual survey work. The crews were spending more time behind the wheel than on rooftops. Project timelines stretched to 8-10 weeks: SunPath’s competitors advertised 4-6 week installation timelines. SunPath averaged 8 to 10 weeks from contract to completion because each project phase was scheduled by availability rather than optimized for efficiency. The survey might happen in week 1, engineering in week 4 (because the crew was booked), and installation in week 8. Homeowners grew frustrated waiting. Revenue per crew limited by drive time: Each crew could realistically handle 2 to 3 site visits per day. Kevin calculated that with better geographic clustering, the same crews could fit 4 to 5 visits. The difference was significant: 2 extra visits per day across 8 crews added up to 16 additional billable touchpoints daily. No documentation for warranty claims: When a homeowner filed a warranty claim months after installation, SunPath had no photographic record of the installation. Disputes about whether panels were mounted correctly, whether flashing was installed, or whether conduit was routed properly became word-of-mouth disagreements between the crew and the homeowner. I pulled up Google Calendar one morning and saw my survey crew scheduled for Mesa at 8am, Gilbert at 10am, and Scottsdale at noon. That’s a triangle across the entire east valley. They spent two hours driving to do an hour and a half of actual surveys. Every single day looked like this. Kevin Park Operations Manager, SunPath Solar Kevin’s frustration went beyond operational inefficiency. SunPath was losing deals because of slow project timelines. Homeowners who signed with SunPath and then waited 10 weeks for installation sometimes canceled during the waiting period, especially when competitor sales reps knocked on their doors offering faster timelines. Kevin estimated SunPath lost 3 to 4 deals per quarter to timeline-related cancellations. The calendar-based scheduling also created a coordination problem. When a crew finished an installation early, Kevin had no quick way to redirect them to a nearby survey or inspection. The crew would call the office, the coordinator would check the calendar, and by the time a nearby appointment was identified and confirmed with the homeowner, an hour had passed. The inefficiency compounded throughout every day. The Solution Kevin found Upper while researching field service routing tools. Most solutions he evaluated were designed for delivery fleets, but Upper’s ability to assign different service durations to different stop types matched SunPath’s needs precisely. A 30-minute survey, a 45-minute engineering assessment, a 5-hour installation, and a 30-minute inspection could all coexist on the same day’s route with appropriate time allocations. He started with the survey and inspection crews since they had the most stops per day and the most to gain from route optimization. Within the first week, the results were clear enough to roll out across all 8 crews. Most route tools are built for delivery drivers doing 30 stops in a day. We do 3 to 5 stops, but they’re all different durations. I needed a tool that understood a 30-minute survey and a 5-hour installation aren’t the same kind of stop. Upper handled that out of the box. Kevin Park Operations Manager, SunPath Solar Geographic Clustering That Doubled Productive Time The core change was simple in concept but transformative in practice. Instead of scheduling by crew availability alone, Kevin now loaded each day’s appointments into Upper and let the route optimization engine cluster them geographically. A survey crew that had been zigzagging across the valley now worked a concentrated area: three Mesa appointments in the morning, two Gilbert appointments after lunch. Average drive time between sites dropped from 35 minutes to 15 minutes. For a survey crew doing 5 visits per day, that freed up nearly 2 hours. Kevin used that recovered time to add appointments. Survey crews went from 4-5 daily visits to 6-7. Inspection crews gained similar capacity. The installation crews benefited differently. Full-day installations couldn’t be clustered on the same day, but Kevin used Upper to schedule consecutive installation days in the same area. A crew installing in Chandler on Monday would handle a Chandler or Tempe installation on Tuesday rather than driving to Surprise. The geographic continuity reduced daily setup time and kept crews in familiar territory. Install Days as Anchors with Shorter Visits Filling Gaps Kevin developed a scheduling method that treated installations as anchor appointments. A 5-hour installation in Scottsdale was placed on the route first. Upper then filled the remaining time with shorter visits in the same area: a 30-minute survey before the installation and a 30-minute inspection afterward. The crew’s entire day was productive and geographically contained. This approach compressed project timelines significantly. Instead of scheduling each project phase independently based on calendar openings, Kevin grouped phases by location. If the survey crew was working Tempe on Wednesday, they surveyed all Tempe projects that needed it. The engineering crew followed with Tempe assessments on Thursday. Installations were scheduled in geographic batches the following week. Real-Time Crew Tracking for Same-Day Redirects Phoenix’s solar market moved fast. Homeowners who requested a survey expected to hear from SunPath quickly. When a crew finished a job early, Kevin needed to redirect them to a nearby prospect before a competitor got there first. Upper’s live fleet tracking showed Kevin where every crew was in real time. When a new survey request came in, he checked the map, identified the nearest crew with remaining capacity, and added the appointment directly through Upper’s dispatch system. The crew’s app updated instantly with the new stop and directions. Response time for same-day survey requests dropped from “we’ll try to get there this week” to “we can be there in an hour.” A homeowner calls at 10am wanting a survey. I check the map, see my Tempe crew finishing early, add the stop, and the crew is on the roof by 11am. That speed closes deals. The homeowner hasn’t even had time to call our competitor. Kevin Park Operations Manager, SunPath Solar Photo Documentation for Installation Records Kevin required all crews to photograph key stages of every installation using Upper’s proof of delivery feature. Roof condition before panel mounting, racking installation, panel placement, electrical connections, conduit routing, and the completed system. Each photo was timestamped and attached to the job record. The documentation solved a problem Kevin hadn’t been able to address before. When a homeowner filed a warranty claim 8 months post-installation arguing that panels were improperly mounted, Kevin pulled the installation photos showing correct mounting with proper flashing and sealant. The dispute was resolved in one meeting. Over the first year, photo documentation resolved 4 warranty disputes that would have previously required sending a crew back to the site for an investigation visit, saving both time and the cost of unnecessary truck rolls. The Impact SunPath Solar’s operational transformation centered on one change: organizing field work by geography instead of calendar availability. The ripple effects touched every part of the business, from crew productivity to revenue per installation to customer satisfaction. The fleet gained 2 extra site visits per day. That number represented the aggregate improvement across all 8 crews, but the distribution varied. Survey and inspection crews, which handled the most stops, each gained 1 to 2 additional visits daily. Installation crews gained efficiency through geographic batching rather than additional stops. The combined effect was a measurable increase in the volume of work SunPath could handle without adding crews or extending hours. Average drive time between sites dropped from 35 minutes to 15 minutes. Crews that had spent nearly half their day driving now spent that time on productive site work. For the survey crews in particular, the shift was dramatic: 2 additional hours of survey capacity per day from a crew that previously had no slack in their schedule. Project timelines compressed from 8-10 weeks to 5-7 weeks. The improvement came from geographic batching of project phases and the additional daily capacity that allowed SunPath to schedule phases closer together. Homeowners moved from contract to completed installation 30% faster. The faster timelines reduced cancellations during the waiting period and improved customer satisfaction scores.

The improvement came from handling more billable appointments per day and from reducing the overhead cost of excessive driving. Fuel savings contributed, but the larger factor was the additional surveys and inspections that converted into signed installation contracts. More surveys meant more proposals, which meant more installs. Kevin restructured SunPath’s scheduling workflow entirely. The project coordinator now enters all upcoming appointments into Upper each morning by type and location. Kevin reviews the optimized routes, makes adjustments for crew specialties or customer preferences, and dispatches. The entire planning process takes 20 minutes, compared to the hour-plus of calendar juggling it replaced. SunPath Solar now runs a field operation where geography drives scheduling, not the other way around. Crews work concentrated areas, projects move faster from contract to completion, and every installation is documented with timestamped photos. In a competitive residential solar market where speed and professionalism win deals, the operational efficiency has become a sales advantage. We used to lose deals because homeowners got tired of waiting 10 weeks. Now we’re completing installations in 5 to 7 weeks, and our crews finish each day having actually worked instead of having driven. The math just works better when your routes make geographic sense.
