Size the system
Use project conditions and product data to develop a practical collector recommendation for pool heating or domestic hot water.
Solar thermal design software
Solar thermal design software for pool heating and hot water.
SunProjeX is a browser based platform for contractors who sell and install solar pool heating and solar domestic hot water. It brings the practical design and sales steps into one connected project.
One connected project
Solar thermal design involves more than a calculation.
A contractor needs a defensible system size, a layout that fits the roof, product information, a clear explanation of expected performance, and a proposal the customer can understand. SunProjeX keeps those steps together instead of scattering them across worksheets, drawing tools, and document templates.
Lay out the roof
Trace usable roof area, account for setbacks and obstructions, and place collectors with visible dimensions and spacing.
Build the proposal
Carry design results into branded customer documents without retyping the project in a separate sales tool.
Purpose built
Solar thermal is a different design problem from PV.
PV software centers on electrical production, modules, inverters, and utility rate modeling. Solar thermal contractors work with collector area, water demand, pool surface area, hydraulics, storage, backup heat, and seasonal performance. SunProjeX is organized around those thermal inputs and the way installers turn them into a sold job.
The platform covers both major residential contractor workflows: solar pool heating design and solar hot water design.
What it is built to connect
- Customer and site information
- Pool or hot water demand
- Collector and tank selection
- Roof geometry and panel placement
- Performance explanation
- Pricing, financing, proposal, and signature workflow
Who it serves
For contractors, dealer teams, and manufacturers.
Owner operators
Move from site information to a consistent design and customer proposal without maintaining a stack of disconnected files.
Sales and design teams
Use the same product data and project workflow across multiple users while keeping proposals tied to the design.
Manufacturers
Place verified products and technical data where contractors make design decisions. See the manufacturer catalog approach.
Common questions
Questions contractors ask
Is SunProjeX photovoltaic design software?
No. SunProjeX is built for solar thermal work: solar pool heating, solar domestic hot water, and projects that combine both systems.
Does SunProjeX run in a browser?
Yes. Contractors can use the platform through a modern web browser without installing desktop simulation software.
Can a contractor create a customer proposal?
Yes. The workflow connects system inputs, roof and collector layout, performance results, pricing, and branded proposal output.
Can contractors use their own collector data?
Yes. SunProjeX includes a product catalog and supports dealer entered products. The source of product performance data should remain clear.
The contractor ecosystem
Connect design with the company that sells, installs, and services it.
SunProjeX handles solar thermal design and proposals. Contractors can carry the broader operation into related ProjeX platforms and prepare for free consumer calculators.
