Solar design inside the system that runs the job

Also in Glow

The roof

Glow finds the roof faces on high-resolution imagery and lays the panels out, best-yielding first.

Your catalogue

Panels, inverters and batteries you actually fit, at your prices, with the datasheet attached.

The MCS compliant estimate

The MIS 3002 performance estimate, with an MGD 005 shade assessment on every roof face.

Then it stops being a design tool

The design becomes the priced proposal, the materials list and the purchase orders on the same job.

Flow, for heat pumps

The fast heat pump estimate from your enquiry form, before anyone books a survey.

Frequently asked questions

What is Glow?

Glow is solar design built into Payaca. You pin the roof, Glow pulls high-resolution imagery, finds the roof faces and lays the panels out, and the design becomes the priced items on the proposal, in the same project your team runs the survey, the DNO application and the invoice from.

Can I use Glow now?

Glow is in limited release with a small group of UK installers running it on real jobs. Book a call and we'll switch it on for your account.

Is the estimate MCS compliant?

The estimate carries the MIS 3002 performance estimate, worked from the MCS zone and the orientation and pitch of the actual roof, with a shade factor per array, and the MCS battery information, with the notes those standards require.

How is shading assessed?

Automatically, on each roof face. Glow runs an MGD 005 shade assessment from the horizon in the surface model and the objects near the property, puts a shade factor on every array and attaches the sun path chart to the estimate. Redraw a face by hand and the document states that array was not assessed.

Where does the equipment data come from?

From a catalogue of panels, inverters and batteries built from manufacturers' datasheets, with the technical data and the datasheet attached to the product, so the spec sheet goes out with the proposal.

What is Flow?

Flow is the heat pump equivalent of the fast estimate, in limited release for UK accounts. A customer fills in your enquiry form, Payaca pulls the EPC, runs the heat loss, sizes the pump and cylinder from your own appliance list and takes off the Boiler Upgrade Scheme grant, so you can send an indicative estimate before a survey is booked. It is the fast estimate, not room by room heat loss.

Do I still need my design tool?

For solar, Glow does the design and the MCS compliant estimate. For heat pumps, Flow gives you the indicative number and your design tool still does room by room heat loss. The existing design tool integrations are unchanged and keep working, so you can run both.

What happens after the design?

The kit on the design becomes the priced items on the proposal, the proposal becomes the materials list, and the materials list becomes purchase orders to your suppliers or a draw from your own stock at real cost. Purchase orders and supplier invoices sync to Xero, so the margin on the job is live from the day it's quoted.
