OpenSolar

OpenSolar is unique in the solar software stack. It removes the subscription cost barrier while still covering the core workflow—layout, production estimates, pricing, and proposals. In practice, it is used during early-stage project development. Sales engineers use it to map rooftops, test system sizes, and generate proposals without switching platforms. The workflow is fast. Designs load quickly, adjustments reflect immediately, and proposals can be generated without exporting data into separate tools.

What is OpenSolar?

OpenSolar is a cloud solar design and sales platform used to develop system layouts, estimate energy production, and generate customer proposals. The platform combines design, project tracking, and financial modelling under one interface. It is primarily deployed in residential and small commercial solar sales workflows. The platform is optimized for speed and accessibility rather than deep technical simulation.

Features

Here’s where OpenSolar starts to feel surprisingly capable:

Fast solar system design

You can draw panels directly onto rooftops using satellite imagery. Tilt, orientation, and shading are handled in the background, so you don’t get stuck tweaking every detail.

Real-time performance simulation

Energy yield updates instantly based on design changes. Includes basic shading and production estimates.

Built-in proposal generation

Create clean, client-ready proposals with system specs, savings estimates, and visuals. No need for external proposal software.

Financial modeling

Includes cash purchase, loan, and lease scenarios. It calculates ROI, payback periods, and savings automatically.

Component database

Access a large global catalog of panels, inverters, and batteries. You can also customize your own equipment lists.

Customer management (light CRM)

Track leads, projects, and proposal status without leaving the platform.

Collaboration tools

Teams can work on projects together, making it easier to review and finalize designs. Permissions are simple but functional.

OpenSolar Pricing

OpenSolar’s pricing is free to use for solar professionals. There are no subscription tiers for core functionality. But instead, Opensolar offers optional paid add-on specific enterprise services. The company monetizes through partnerships and optional services rather than charging installers directly. That said, “free” comes with trade-offs. You won’t get the depth of highly specialized simulation tools, but for most residential and small commercial projects, it covers what you need.

Integrations

OpenSolar connects with a few useful tools to streamline your workflow:

• CRM systems for lead tracking
• Financing providers for loan and lease options
• Hardware databases for up-to-date component specs
• Proposal and document workflows

The ecosystem isn’t massive, but it’s practical. Most installers won’t feel blocked.

Send the proposal digitally for review and approval.

FAQs

Is OpenSolar suitable for commercial-scale projects?

It can handle small commercial systems. For complex or utility-scale projects, additional engineering tools are typically required.

Does it support battery storage integration?

Yes. Battery systems can be included in designs and proposals.

How reliable are production estimates?

They are suitable for sales-stage analysis. Detailed engineering validation should be done separately.

Can multiple team members collaborate?

Yes. Projects can be accessed and edited by multiple users.

Does OpenSolar work worldwide?

Yes. It supports global locations with localized solar data and equipment databases.

Does OpenSolar replace dedicated CRM software?

For many users, yes. But advanced users may still pair it with specialized simulation tools.

Is customization available for proposals?

Limited. Branding can be added, but layout and structure options are constrained.

What type of installer benefits most from OpenSolar?

Small to mid-sized residential installers and sales-focused teams benefit the most due to cost savings and workflow speed.
