The problem

Too many tools, too much scattered data

Photovoltaic installers juggle leads, quotes, projects and invoicing every day — often across spreadsheets and disconnected tools. The result: scattered data, missed follow-ups and valuable time lost on admin work.

  • Data scattered across multiple spreadsheets

    Quotes in one file, clients in another, stock in a third — and none of them agree.

  • Missed follow-ups and client reminders

    A lead goes quiet for three weeks and nobody notices until the deal is already gone.

  • No visibility on project progress

    Nobody can say where an installation stands without calling the technician on site.

  • Contracts and documents impossible to find

    Contracts, permits and certificates buried in inboxes on the day the client asks for them.

Solis System brings it all together — organized, automated and accessible everywhere.

FAQ

Questions solar installers ask us

Straight answers about what Solis System does, who it is for and how to get started.

What is Solis System?

Solis System is an all-in-one CRM and ERP platform for solar and photovoltaic companies. It replaces the spreadsheets and disconnected tools installers normally use, bringing leads, quotes, customer invoices, payments, supplier purchases, after-sales, inventory and scheduling into one workspace. It is published by OPSX and runs in the browser, in French and English.

Is Solis System an ERP or a CRM?

Both, in a single tool. The CRM side handles the commercial relationship — leads, pipeline, follow-ups, quotes and customer history. The ERP side runs operations — projects, team scheduling, panel and inverter stock, after-sales and documents. Because everything shares one database, a lead becomes a quote, a quote becomes a project and a project becomes an after-sales case with no re-entry. You do not need to buy an ERP on one side and a CRM on the other, then make them talk to each other.

Who is Solis System for?

It is built for photovoltaic installers and solar energy companies — from a small team of technicians to a company running dozens of jobs at once. Sales staff work the pipeline and send quotes, finance teams issue invoices and follow payments, service teams coordinate maintenance, and management watches the KPIs and cash position on the dashboard.

Is Solis System suited to the Tunisian market?

Yes. Solis System is built in Tunisia by OPSX for Tunisian photovoltaic installers, with a French interface, French quotes and a support team reachable locally in Tunisia by phone or WhatsApp on +216 28 035 320. Processes, quote templates and stock rules are adapted to the way you work before going live — something a generic foreign tool does not offer.

Which modules does Solis System include?

Fourteen modules ship as standard: Dashboard, CRM Pipeline, CRM Overview, Quotes, Finance, Purchases, Calendar, After-sales (SAV), Inventory, Notifications, Settings, Workspace, Account and full mobile access. They share one workspace, so sales, finance, service and stock teams work from the same client, product and task information.

Can Solis System manage invoices and payments?

Yes. Finance handles customer invoices, partial payments, credit notes and refunds, with live outstanding balances. It also provides registers and Excel exports for invoices, payments, credit notes, quotes and purchases, plus dashboard visibility of billed, collected and supplier balances.

Can Solis System produce photovoltaic quotes?

Yes. The Quotes module turns your stock products into a professional solar quote and exports it as a PDF in a few minutes. Quote templates, pricing rules and prospect types are configurable in Settings, so recurring panel, inverter and mounting configurations are priced consistently rather than rebuilt by hand each time.

Does it handle after-sales and maintenance?

Yes. The after-sales module (SAV) tracks breakdowns, scheduled maintenance and warranty repairs against the original installation, so the technician who takes the call already has the site history, the equipment installed and the documents. After-sales appointments land on the same team calendar as installations.

Does Solis System work on mobile in the field?

Yes. The full CRM runs on any smartphone browser with nothing to install and everything in sync, so a technician can update a job, check stock or open a client document from the site. Installation status changes made in the field are visible to the office immediately.

Is Solis System available in French and English?

Yes. The interface, the quotes and the support are available in both French and English, and each user picks their own language in their account settings — the same workspace can run a French-speaking field team and English-speaking management.
