OpenSolar

OpenSolar is a platform for solar professionals to design, sell, and manage projects, with a free OpenSolar Pro plan. Its Ada AI can produce multiple solar system designs based on design preferences. Users can make customizable, branded proposals with flexible payments and real-time updates, then manage branded invoices, payment milestones, reminders, online payments, and e-signatures. The design experience supports equipment orders, while a hardware catalogue can generate a bill of materials. An API connects with CRM, accounting, operations, and incentive tools, handling project, design, pricing, hardware, and contact data. API Access is a paid add-on with a 30-day free trial; billing begins at the start of the closest month after the trial, and its fee is geo-specific and per-project. OpenSolar says it encrypts stored and transmitted data and uses role-based access controls. It targets 99.95% availability and monitors systems around the clock. Free accounts include dedicated 24/7 support, alongside live help, tickets, training, webinars, and a Help Center. The platform is available on Android, iOS, macOS, web, and through an API.

OpenSolar Pro brings solar design, sales, and project management into a free platform. API Access has a separate trial and per-project, geo-specific pricing, so teams should consider that distinction when planning integrations.

OpenSolar is intended for solar installers, sales teams, and energy professionals. It may suit teams seeking design, sales, and project-management tools, with API connections to business systems.

Overview

OpenSolar is a solar project platform that brings system design, customer proposals, payments, and project management together. It is best suited to solar installers and sales teams looking to manage that workflow without a subscription for the core product. Its breadth is a strength, though teams that need API integrations should account for a separate, project-based charge.

Key features

Design and sales

Ada AI generates multiple solar system designs based on design preferences in seconds. That can help teams move from design options into customer conversations without treating design as a separate tool. Customizable, branded proposals support flexible payments and real-time updates, keeping customer-facing materials connected to the evolving project.

Payments and project operations

Branded invoices, payment milestones, automated reminders, online payments, and e-signatures cover several steps between proposal and collection. Equipment ordering within the design experience and bill-of-materials generation from a hardware catalogue make the design workflow useful for preparing purchases as well.

Site survey forms and design handoff support work before installation, while crew scheduling and service visit tracking extend the product into ongoing operations. That range makes OpenSolar more than a design-and-proposal tool, but teams should still assess whether its project workflow suits their own processes.

API, security, and support

API Access connects OpenSolar with CRM, accounting, operations, and incentive tools, and supports project, design, pricing, hardware, and contact data. The separate add-on is most relevant to teams building integrations; its project-based fee means it is not simply an included extension of the free Pro offer.

OpenSolar says it encrypts stored data and data in transit using TLS/SSL, applies role-based access controls, and targets 99.95% service availability with 24/7 monitoring. The platform is hosted on AWS, with production systems in Sydney and a global content delivery network. Free accounts include dedicated 24/7 support, with live support, ticket help, training, webinars, and a Help Center.

Pricing

OpenSolar Pro

OpenSolar Pro costs nothing, billed Free of charge. It includes solar design, sales, and project management, making it a strong fit for teams that want a broad core workflow without subscription costs. The free offer includes dedicated 24/7 support. Its main qualification is that API Access is a paid add-on rather than part of Pro.

OpenSolar API Access

API Access has custom pricing, billed as a per-project fee with geo-specific pricing. A 30-day free trial is available; after the trial, billing starts at the beginning of the closest month. Since the fee applies when a project is created, teams should consider expected project volume and location when planning integration costs.

Platforms

OpenSolar supports Android, iOS, macOS, and web, with API access offered separately. The platform mix suits teams working across mobile and desktop, while integration use carries its own pricing terms.

Who it's for

OpenSolar is aimed at solar installers, sales teams, and energy professionals who want design, sales, payments, and project administration in one platform. It is particularly compelling for teams that can use Pro without API integration costs. Businesses that depend on connecting CRM, accounting, operations, or incentive systems should weigh the separate API fee before committing to that workflow.

Pros and cons

• Pro is free: Solar design, sales, and project management are included without a subscription charge.
• Broad project coverage: Design, proposals, payments, equipment ordering, surveys, crew scheduling, and service visit tracking span more than the sales stage.
• API costs are separate: Geo-specific, per-project billing can complicate budgeting for teams creating many projects through integrations.
• API billing follows the trial: After the 30-day trial, charges begin at the start of the closest month, so trial timing matters to teams evaluating the add-on.

Verdict

OpenSolar is a strong choice for solar installers and sales teams that want design, customer transactions, and project management in one free platform. Its main advantage is the breadth of Pro without a subscription; its main reason to look elsewhere is the separate, geo-specific API fee for teams that need integrated project data.
