Solar thermal design and proposal software for contractors who install pool heating and domestic hot water. Size systems, lay out collectors on the roof, model performance, and build customer-ready proposals in one browser workflow.
Scroll to exploreAurora, HelioScope, and OpenSolar give PV contractors purpose built tools for array design, production modeling, and proposals.
Solar pool heating and solar hot water contractors? They size on a paper form, build proposals in Word, and explain swim seasons with a marker on a sample board.
SunProjeX is built around the field and sales workflow of contractors who install solar pool heating and solar hot water.
Most thermal contractors do both. Most software does neither. SunProjeX runs the math for each system natively, then ties them into a single homeowner proposal when they share a roof.
Size the array, model the swim season, show the homeowner exactly how much longer the pool stays comfortable.
Demand-and-offset math the way SRCC actually intends it. No more guessing at tank size or collector count.
When pool heat and DHW share the same roof, SunProjeX builds one proposal, one financing scenario, and one install timeline. Close both systems in the same in-home appointment.
No bloated PV features you'll never touch. Just the tools that close pool heat and hot water deals.
Show homeowners exactly when they'll be swimming, month by month, before and after solar.
SRCC-aligned hot water modeling. Real annual solar fraction, not best-case fantasy numbers.
Sub-meter Mapbox imagery and Google Solar API for instant roof intelligence: pitch, azimuth, and sun-hours per segment.
White-labeled PDFs ready for the customer's hands. Your logo, your colors, your numbers. See a sample →
Plumb the array on real roof geometry. Headers, returns, and tilt without back-of-napkin math.

Use FSEC reference methods and SRCC-rated product data where applicable, with project assumptions visible for contractor review.
From address entry to a branded PDF the homeowner can hold. Built for the way contractors actually work.
SunProjeX pulls local irradiance, climate zone, and roof geometry from public data.
Pool dimensions, household size, fixture count, backup type. The sizing engine does the rest.
Collectors, plumbing, controller logic, swim season chart, and offset percentages auto-generate.
Branded PDF with system specs, financing scenarios, and the close. Sign on the spot.
How pool surface area, climate, the roof, screens, covers, and collectors affect solar pool heating size.
How demand, collector area, storage, system type, backup heat, and climate shape solar hot water sizing.
