Nirav Dhanani SolarPlus is a cloud-based solar design and proposal software used by residential installers to lay out rooftop arrays, estimate production, and generate customer quotes. Like similar tools, its outputs are a sales starting point; a permit set for a US jurisdiction still needs engineering review against NEC 2023 Article 690 and local code.
Key Takeaways
- SolarPlus = residential solar proposal/design platform.
- Competes with Aurora and OpenSolar.
- Smaller-installer focus.
- Subscription pricing.
Where SolarPlus Fits
SolarPlus occupies the same general category as Aurora Solar and OpenSolar: a cloud-based tool that takes a residential rooftop from a rough layout through a customer-facing proposal.
The main difference between these platforms tends to be scale and pricing rather than core functionality, Aurora leans toward larger installers who need deep CRM and financing integrations, OpenSolar leans toward cost-sensitive markets with a free, commission-funded model, and SolarPlus positions itself toward smaller residential shops that want a simpler, subscription-based alternative to either.
For an installer evaluating design software, the practical question is usually the same regardless of which of these three platforms you’re comparing: is the tool being used to close a residential sale, or to produce the engineering documents a jurisdiction will actually stamp and approve?
Sales-and-proposal platforms like SolarPlus are built for the former. Once a deal is signed, most installers still route the project through a dedicated permit design or detailed engineering design process to get an AHJ-ready single-line diagram and structural package.
