Solar design software
One browser-based platform for the whole design workflow: site model, module layout, shading analysis, yield and financial simulation, and the client proposal. Built by the team behind Heaven Designs, for solar companies that design in-house.
SurgePV is a product of SurgePV Technologies Ltd, London. Heaven Designs introduces it here as a software partner.
The problem
Most solar teams do not have a design problem. They have a handoff problem. The layout lives in one tool, the yield in another, the financials in a spreadsheet and the proposal in a deck, and the only thing holding the four together is someone remembering to update all of them.
SurgePV closes that gap by keeping the whole sequence on one project. Site model, module layout, stringing, shading, yield, financials and the client document are steps in a single workflow rather than four files that have to be reconciled by hand.
Book a DemoA CAD package for the layout, a simulation engine for the yield, a spreadsheet for the financials and a slide deck for the client. None of them share a model.
Module counts, tilt, azimuth and losses get retyped at every handoff. Each retype is a chance for the proposal to disagree with the design.
A moved array or a swapped inverter means redoing the simulation, the financials and the document, in that order.
Obstructions missed at design stage turn into production shortfalls, redesigns and difficult conversations after the sale.
The product
SurgePV website, opens in a new tab SurgePV is cloud-based solar design software for solar professionals. It runs in the browser, which means designs open on any machine and the team works on the same project rather than passing files around.
It is built for solar businesses: installers, EPCs, in-house design teams and the sales people who have to put a credible document in front of a customer. It is not a consumer tool, and it is not a CRM.

Inside the platform
SurgePV markets five core product areas. They are steps in the same workflow, not separate purchases.
Build the site model from an address. SurgePV generates a 3D roof from satellite imagery, then places modules across the planes you keep.
Hourly shade and irradiance modelling over the site model, so obstructions show up in the layout rather than on the roof.
Yield simulation and financial modelling on the same design, with the assumptions written down next to the numbers.
Client-facing proposals generated from the design that produced them, so the numbers in the document match the model.
A solar-trained assistant inside the project rather than a general-purpose chatbot. It reads the design and answers against it.
The fastest way to judge any of this is to watch a site you already know get modelled, simulated and turned into a proposal.

Site model
SurgePV builds the 3D roof from satellite imagery for the address, keeping separate planes for each pitch and azimuth. Dormers, setbacks and obstructions are traced in the same view, so the layout that follows is constrained by the actual roof rather than an approximation of it.
Electrical
DC stringing runs against the array you designed, with MPPT ranges, string counts and inverter selection resolved in place. Because the electrical design and the geometry share one model, a moved array does not silently invalidate the stringing.
Simulation & finance
System size and estimated production carry straight into pricing, LCOE, IRR, first-year savings and payback. Change the layout and the financial case updates with it, which removes the most common reason a proposal disagrees with the design behind it.
Proposal
The proposal and the shade report are generated from the project that produced them, branded and ready to send. Nothing is retyped into a deck, so the system size, shading figure and price in front of the customer are the ones in the model.
Who it is for
SurgePV sells to solar businesses, not to homeowners. These are the groups it markets to directly.
The primary audience — teams that design systems and issue proposals, from a solo designer to a 50-person EPC.

The two are separate businesses with a shared origin. SurgePV's about page states that it was founded by the team behind Heaven Designs, and that Keyur Rakholiya, founder of Heaven Designs, is its CEO and co-founder. Heaven Designs does not own or resell SurgePV.
You send the project, our engineers produce the package. This is the right route when the work needs stamped or constructible output, structural calculations, or a permit set that will be reviewed by an AHJ.
SurgePV website, opens in a new tab Your designers work in the platform themselves. This is the right route when you have the people, run enough volume to want the workflow in-house, and need the proposal out the same day.
Plenty of teams use both: the software for volume design work they keep in-house, an engineering partner for the packages that need a stamp, a structural report or a reviewer's approval.
When the layout, the simulation and the proposal share a project file, a revision propagates instead of starting a chain of manual updates.
Shading, solar access thresholds and string limits are applied while the design is still on screen, which is considerably cheaper than finding them on a roof.
A repeatable workflow lets a small team take on more projects without every design routing through the one person who knows the CAD file.
