SolarPlus

SolarPlus is a solar proposal and design platform used by some residential installers.

Definition

SolarPlus is a cloud-based residential solar design and proposal platform. Competes with Aurora and OpenSolar in the small-to-mid-size installer market.

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.

Frequently Asked Questions

5 commonly searched questions about SolarPlus.

What is SolarPlus?
SolarPlus is a cloud-based residential solar design and proposal platform. Like Aurora Solar and OpenSolar, it targets installers who need rooftop layout, a customer-facing proposal, and financing options in one workflow, with a focus on smaller residential shops rather than large enterprise sales teams.
How does SolarPlus compare to Aurora Solar?
Aurora Solar is the more established, feature-rich platform with deeper CRM and financial-modeling integrations, and it dominates the US residential market. SolarPlus competes on a smaller-installer footprint and generally lighter subscription pricing, similar in positioning to how OpenSolar competes with Aurora on cost.
Is SolarPlus suitable for commercial solar projects?
No. SolarPlus is built around residential rooftop sales and design, the same market segment as Aurora and OpenSolar. Commercial and utility-scale projects need bankable simulation software such as PVsyst or HelioScope, followed by a dedicated detailed engineering design pass.
Does SolarPlus produce permit-ready drawings?
SolarPlus is positioned as a sales and design proposal tool, not a source of AHJ-ready, PE-stamped construction documents. Installers using SolarPlus to close a deal typically still need a separate permit design service to turn the proposal into a stamped single-line diagram and structural package.
Who should consider SolarPlus instead of Aurora or OpenSolar?
Smaller residential installers who want a lighter-weight, lower-cost design and proposal tool are the typical fit. Larger teams that need extensive CRM integration, financing partner networks, or enterprise-scale reporting usually gravitate toward Aurora Solar instead.
