Design in Payaca, or in the tool you already use
Solar design is now native, with Glow. Heat pump estimates are native, with Flow. The EasyPV, Heatpunk, OpenSolar and Spruce integrations are unchanged and still work.
Import design
Connected“Key things for us were integration with AI, renewables, alignment with our vision.”
There are now two ways to design in Payaca. Glow does solar design natively: pin the roof, lay the panels out from your own catalogue and send an MCS compliant estimate from the project the job already runs in. Flow does the fast heat pump estimate from your enquiry form. Both are in limited release for UK installers.
If you design somewhere else, nothing changes. UK clean tech installers rely on specialised design tools. EasyPV and OpenSolar for solar PV, Heatpunk and Spruce for heat pumps. Payaca still connects to all of them, and those integrations keep working exactly as they did.
Design in the tool you know best, and system specifications, equipment lists, and pricing flow directly into professional proposals. No re-keying data, no copy-paste errors, no time wasted on manual entry.

What's included
The native option and the integrations, side by side.
Glow: solar design in Payaca
Native solar design. Pin the roof, Glow pulls high-resolution imagery, lays the panels out from your own catalogue and builds an MCS compliant estimate in the same project as the survey, the DNO application and the invoice. In limited release.
Flow: heat pump estimates
Native heat pump estimating. A customer fills in your enquiry form, Payaca pulls the EPC, runs the heat loss and sizes the pump and cylinder from your own appliance list, so an indicative estimate goes out before a survey is booked. It is the fast estimate, not room by room heat loss.
EasyPV Integration
Design solar systems in EasyPV with Magic Mode, 3D modelling, or Quick Roof. Specs sync directly into quotes.
Heatpunk Integration
Run MCS-compliant heat loss calculations in Heatpunk. System sizing and equipment specs flow into proposals.
OpenSolar Integration
Create stunning solar designs with shade analysis. System specs, pricing, and imagery sync into quotes.
Spruce Integration
Design heat pump systems in Spruce. Heat loss calculations and equipment specs flow seamlessly into proposals.
Design File Storage
Keep every design file with the project - CAD single-line diagrams and elevations (DWG, DXF, IFC), heat loss calculations, and full survey packs up to 250MB. No more emailing large files around.

Frequently asked questions
- Can I design solar inside Payaca?
- Yes. Glow is native solar design in Payaca. You pin the roof, Glow pulls high-resolution imagery, finds the roof faces and lays the panels out from your own catalogue, and the design becomes an MCS compliant estimate on the project. Glow is in limited release for UK installers.
- Can I estimate a heat pump without a design tool?
- Flow produces an indicative heat pump estimate from your enquiry form. Payaca pulls the EPC, runs the heat loss and sizes the pump and cylinder from your own appliance list, so a number goes to the customer before a survey is booked. It is the fast estimate, not room by room heat loss, so your design tool still does that part.
- Do the design tool integrations still work?
- Yes. EasyPV, Heatpunk, OpenSolar and Spruce are unchanged. Glow and Flow are an additional native option, not a replacement, and plenty of installers will run both.
- Which UK design tools does Payaca integrate with?
- Payaca integrates with EasyPV (solar PV design with Magic Mode and 3D modelling), Heatpunk (MCS-compliant heat loss calculations), OpenSolar (solar design with shade analysis), and Spruce (heat pump system design).
- How does the EasyPV integration work?
- Design solar systems in EasyPV using Magic Mode, 3D modelling, or Quick Roof. When your design is complete, system specifications, equipment lists, and pricing sync directly into a Payaca proposal.
- Does the Heatpunk integration support MCS compliance?
- Yes. Heatpunk produces MCS-compliant heat loss calculations, and these flow directly into Payaca proposals. System sizing, equipment specifications, and documentation requirements are all captured.
- Can I use multiple design tools with Payaca?
- Yes. Many installers use EasyPV or OpenSolar for solar designs and Heatpunk or Spruce for heat pump designs. Payaca connects to all of them, so whichever tool you use, the data flows into your quotes.
- Can I store CAD files and large survey packs in Payaca?
- Yes. Design files, CAD single-line diagrams and elevations (DWG, DXF, IFC), heat loss calculations, and full survey packs up to 250MB are stored with the project. Your team can access everything from one place, on any device, so the job record is the full picture rather than a link to a file in someone's inbox.
