Solar ERP

Solar ERP is a web-based ERP for solar installation companies, combining sales, project operations, monitoring, and quoting. Its broad workflow coverage and high-volume free plan make it worth considering for installers consolidating work across office and field teams. The main trade-off is that Pro requires an annual commitment, while companies with 100 or more users need custom pricing.

Overview

Solar ERP’s case rests on range: a 21-stage sales pipeline sits alongside work orders, inventory, fleet management, permitting, monitoring, and proposal generation. For a company that wants those workflows under one roof, that breadth is more compelling than a single-purpose solar tool. The free plan also has no stated caps on users, projects, or monitored systems, making it a practical starting point for teams assessing the platform.

That breadth may be more than a small installer needs, and the paid step is substantial: Pro is advertised from $495/month with an annual subscription. Scale is another dividing line, since organizations with 100 or more users must move to custom pricing.

Key features

From sales pipeline to field operations

The solar CRM and 21-stage project pipeline give teams a structured route from sales into delivery. Work orders, multi-location inventory, fleet management, GPS-enabled timesheets, permitting, engineering queue tracking, crew scheduling, and design handoff extend that coverage into day-to-day operations. This is a useful combination for installers coordinating office staff, crews, and equipment; companies with simpler workflows may not benefit from managing all of them in an ERP.

Monitoring and proposals

Connections to Enphase, SolarEdge, and Tesla sync monitoring data automatically every 15 minutes. That cadence gives teams regular system updates without manual syncing, though it is not a live-refresh promise. Solar and detach-and-reset calculators account for labor, materials, overhead, and margin, then produce PDF proposals. QuickBooks, OpenSolar, Podio, Nearmap, and e-signatures round out the named integrations and connections.

Security and support

Solar ERP’s privacy policy describes TLS 1.2 or higher encryption in transit, AES-256 encryption at rest, database row-level security, and role-based access controls. After an account ends, data is retained for 30 days for export and may remain in encrypted backups for up to 90 days after deletion from primary systems. General support is handled through a contact form, with a team member reviewing submissions and responding promptly.

Pricing

Free is unusually generous on volume: the published plan has unlimited users, projects, and monitored systems. It is the sensible place to start if those limits matter more than Pro’s added tools and support. There is no free trial, but the free plan provides an ongoing alternative to a time-limited evaluation.

Pro is for teams that need the customer portal, AI tools, premium calculators, or advanced reporting. The price is presented both as $725 a month and as billed from $495/month with an annual subscription ($5,940/year); the annual commitment is the key term for buyers to weigh. Pro supports up to 100 users, while companies with 100 or more require Enterprise. Enterprise adds security, integration, multi-branch, and higher-touch support features, but its price is custom rather than fixed.

Platforms

Solar ERP is web-based. That suits teams coordinating work through a browser, but the platform list does not include a dedicated mobile app.

Who it's for

Solar ERP fits solar installation companies that want sales pipeline management, field operations, monitoring, and quoting in one system. Its unlimited Free plan is especially relevant to teams that need room for users, projects, and monitored systems without a stated volume cap. Pro is a better fit when its added customer-facing, reporting, calculator, or support tools justify the annual bill. Larger organizations with at least 100 users need to evaluate Enterprise and its custom pricing.

Pros and cons

• Broad coverage for installers: sales, project stages, field operations, monitoring, and proposals sit in one platform, which suits companies trying to coordinate those workflows together.
• Generous Free limits: unlimited users, projects, and monitored systems make it usable beyond a small trial group.
• Monitoring connections and proposal tools: automatic syncing every 15 minutes and calculators that include costs and margin support ongoing system oversight and quoting.
• Meaningful annual price step: Pro is billed annually from $495/month, so the paid tier is a larger commitment than the free plan.
• Scale requires custom pricing: companies with 100 or more users cannot use Pro and must consider Enterprise.
• Web-only platform listing: teams seeking a dedicated mobile app should compare alternatives.

Verdict

Solar ERP is a strong choice for solar installers that want sales, field operations, monitoring, and quoting coordinated in one web platform, especially if the Free plan’s unlimited users, projects, and monitored systems meet their needs. Choose Pro when its added tools justify an annual commitment; look elsewhere if you need a dedicated mobile app, a fixed Enterprise price, or a Pro plan for 100 or more users.
