QuickEstimate runs your solar sales workflow. SurgePV handles the engineering half of the same deal: an AI roof model built from satellite imagery, module layout, shading and yield simulation, project financials, and a client-ready proposal, in one browser-based platform built for installers and EPCs.
One is a sales problem. The other is an engineering problem. Most solar businesses lose time where the two meet.
QuickEstimate is where the commercial side of your business lives: leads land, get routed to a rep, turn into a subsidy-ready proposal, go out on WhatsApp, and get chased until they close or die. It is deliberately fast and deliberately shallow on engineering, because a salesperson standing in someone's driveway does not need a shading study.
SurgePV is where the technical side lives: the roof gets modelled, the modules get placed, the shade gets simulated hour by hour, the yield gets forecast, and the economics get worked out before anyone commits to a number. That work decides whether the deal you closed is a deal worth having.
They are two separate products from two separate companies, both in the Heaven Group. SurgePV Technologies Ltd is registered in London and states on its about page that it was founded by the team behind Heaven Designs. There is no automated data sync between SurgePV and QuickEstimate, so use each for the part of the job it was built for.
Three things SurgePV is built to change about the way a technical solar project gets put together.
SurgePV positions itself as a replacement for the usual stack: a CAD tool for the layout, a simulation engine for the yield, a proposal builder for the client, and a spreadsheet holding it all together. Design, shading, energy, financials and proposals sit in one place, so nothing gets re-keyed between them.
The roof model comes from satellite imagery, so shading, irradiance and module placement can be worked out before anyone gets on a ladder. Obstructions like trees, chimneys and neighbouring buildings are modelled in, and a full-year shade simulation shows where the losses actually land.
Yield is reported at P50, P75 and P90 confidence levels off TMY weather data with a full loss chain behind it, and the economics come out as ROI, IRR, NPV, payback and LCOE rather than a single savings figure. SurgePV states its reports are accepted in 18+ countries.
Four steps, one platform, one set of project data carried through all of them.
SurgePV builds a 3D roof model from satellite imagery, including dormers, multi-tilt faces and awkward geometry; the company states most models generate in under 60 seconds. Modules are then placed automatically or by hand across flat, shed and pitched surfaces, with code-compliant fire-safety pathways preserved.
An 8,760-hour annual simulation shows when and where shadows fall across the array, with trees, chimneys and neighbouring structures modelled as obstructions. Every roof surface gets a colour-coded irradiance map, so the losses are visible per face rather than averaged away.
Yield forecasts run off TMY weather data with the full loss chain applied and come out at P50, P75 and P90. The financial layer converts that into ROI, IRR, NPV, payback and LCOE, with cash, loan, lease and PPA structures compared side by side in the local currency and tariff.
The proposal is generated from the design rather than rebuilt in a slide deck. Bill of materials, 3D visuals, monthly production and the financial summary are pulled straight through, white-labelled to your brand, and shared as an interactive web link or a PDF.
SurgePV ships an in-app assistant called Clara AI. It works alongside the design view with actions such as Smart-Trace, Smart-Fill, Map-Obstacles and Modify Design, so parts of the modelling work can be described rather than drawn.

The six capabilities SurgePV publishes on its own product pages.
Satellite imagery becomes a 3D roof model covering dormers, multi-tilt faces and complex geometry. SurgePV states most models generate in under 60 seconds.
Automatic or manual module placement across flat, shed and pitched roofs, with lasso editing, measurements and fire-safety pathways.
An 8,760-hour annual shade simulation with obstruction modelling and per-surface irradiance maps for every roof face.
TMY weather data and a full loss chain, soiling through inverter clipping, producing P50 / P75 / P90 yield and a monthly breakdown.
ROI, IRR, NPV, payback and LCOE, with tariff and incentive modelling and cash, loan, lease and PPA compared side by side.
White-label web or PDF proposals carrying the 3D visuals, auto-generated bill of materials and financial summary, in multiple languages.

One runs the sale. The other engineers the system. Neither one does the other's job, and that is the point.
Sales workflow Design workflow QuickEstimate and SurgePV are separate products. Nothing on this page describes an integration, a data sync or a shared account between them.
SurgePV describes its users in four groups, across every project size.
Teams designing several projects a week who want the roof model, layout, single-line diagram and bill of materials to come out of one tool.
Reps who need an interactive, branded proposal with savings, tariff and payback laid out clearly enough to be shared with a family or a board.
Designers running shading studies, string sizing and yield simulation who want the bankable report and the client document generated from the same model.
Channel teams overseeing partner projects from design through install, with custom API integrations and detailed site assessments.
Design, simulation, financial modelling and proposals in one platform, built for installers and EPCs working from residential rooftops to utility-scale sites.
