Solar ERP

Solar ERP is a web-based ERP for solar installation companies that want sales, delivery, monitoring, and quoting in one system. It suits installers coordinating office, engineering, warehouse, and field crews; organizations needing only design or a lightweight mobile tool may find its scope excessive. The free tier is unusually generous on volume, while the paid tiers add the controls and support expected by larger operations.

Overview

Solar ERP brings a solar CRM and 21-stage project pipeline together with work orders, permitting, engineering queues, inventory, fleet activity, and timesheets. That end-to-end structure is valuable when handoffs between sales and installation are a source of delay or duplicated data. Crew scheduling and design handoff extend the workflow beyond a basic CRM.

The platform is web-only, so it fits teams working from browsers rather than companies requiring dedicated mobile applications. Its broad remit can also be unnecessary for a small installer that needs one narrow function. The biggest commercial divide is between the free tier and Pro's annual commitment.

Key features

Sales and delivery control

The 21-stage pipeline gives managers a defined route from lead through project progress. Work orders, permitting, engineering queue tracking, GPS-enabled timesheets, crew scheduling, and fleet management connect administrative planning with field execution. Multi-location inventory is particularly relevant to installers moving equipment among branches or jobs, although a small team with one warehouse may not use all of that depth.

Monitoring connections

Solar ERP connects with Enphase, SolarEdge, and Tesla for system monitoring, synchronizing automatically every 15 minutes. That cadence reduces the need for manual status checks when managing installed systems, provided the business operates with those ecosystems. QuickBooks, OpenSolar, Podio, Nearmap, and e-signature connections broaden its place in an existing software stack.

Quotes and customer access

Solar and detach-and-reset calculators account for labor, materials, overhead, and margin, then produce PDF proposals. This is more useful than a simple price list when margins vary by job type. Pro adds a customer project portal, letting clients follow work through a dedicated interface, alongside AI tools and advanced reporting.

Security and retention

Data is encrypted in transit with TLS 1.2 or higher and at rest with AES-256. Database row-level security and role-based access controls support separation between users and records. After termination, data is retained for 30 days for export and may remain in encrypted backups for up to 90 days, so departing customers should plan their export window.

Pricing

Plan	Price	Included limits and features
Free	free, billed $0/forever	Unlimited users, projects, and monitored systems
Pro	$725 a month; from $495/month with annual subscription ($5,940/year)	Up to 100 users; unlimited projects and monitored systems; AI tools, premium calculators, customer portal, advanced reporting, migration support, priority email support
Enterprise	Custom pricing	For companies with 100+ users; unlimited projects and monitored systems; custom APIs, SSO/SAML, audit logs, advanced permissions, multi-branch support, and phone/video support with a priority SLA

Free is a credible starting point for a growing installer because its user, project, and monitoring allowances do not impose a stated volume ceiling. It does not include the Pro-specific AI, portal, premium calculators, reporting, migration assistance, or priority support. Pro is aimed at established teams that need those capabilities and can accept a $5,940 annual bill; the advertised monthly figure applies with annual billing. Companies at 100 users or above must use Enterprise custom pricing rather than Pro. There is no free trial, so evaluation starts with the permanent free tier.

Platforms

Solar ERP runs on the web. That is convenient for browser-based office and field coordination, but businesses seeking native Android or iOS applications should compare mobile-first alternatives.

Who it's for

Choose Solar ERP when a solar installation company needs one operational record spanning CRM, project stages, crews, inventory, permitting, monitoring, and proposals. The free plan also suits teams that want to consolidate substantial project or system volume before paying. It is less suitable for a design-only practice, a very small operation with simple workflows, or a business requiring native mobile apps.

Pros and cons

Pros

• Broad solar workflow: sales, delivery, inventory, fleet, permitting, monitoring, and quoting are covered in one platform.
• Generous free limits: unlimited users, projects, and monitored systems make the entry tier usable beyond a short demo.
• Operational automation: monitoring syncs every 15 minutes and calculators include overhead and margin.
• Enterprise controls: SSO/SAML, audit logs, advanced permissions, multi-branch support, and priority SLA support address larger organizations.

Cons

• Large paid commitment: Pro starts at $495/month only on annual billing, totaling $5,940 per year.
• 100-user ceiling on Pro: larger companies must negotiate Enterprise pricing.
• Web-only access: there is no listed native mobile platform.
• No trial period: teams cannot trial a separate time-limited paid plan.

Alternatives

For a wider category comparison, see Solar Installation Software.

• OpenSolar is the better pick for free solar design, sales, and project management across Android, iOS, macOS, web, and API environments, with a free trial.
• FieldExecutives fits teams wanting a paid field platform with Android, iOS, and web apps, a free plan for up to two users, and a free trial.
• InstalTrack is a lower-cost option with a free plan covering up to 10 projects and 50 stages, all features, and an Android app.
• SolarEdge Go is appropriate when free Android and iOS monitoring for SolarEdge systems is the sole requirement.
• SenseHawk is a paid alternative available on Android, iOS, and web.
• SolarSAAS suits buyers seeking contact-priced plans with AI solar design, CRM, and inventory features across a broad platform range.
• Aurora Solar is a paid design-focused choice, with Basic at $159 per user monthly and Premium at $259 per user monthly.
• MightyFields Solar is a per-user SaaS alternative with a 15-user minimum.

Verdict

Solar ERP is a strong choice for solar installers that want a single, solar-specific operating system from lead management through field work, monitoring, and proposals. Its unlimited free-tier volumes make initial adoption practical, while Pro and Enterprise add the reporting, support, security controls, and integrations larger teams need. Look elsewhere if you require native mobile apps, only need design or monitoring, or cannot justify an annual Pro commitment.
