PowerOn is an integrated modular ERP built on Odoo for solar PV installation companies. It connects sales, project management, purchasing, inventory and accounting in a single system, so a quotation, an installation project, an equipment order and the resulting invoice all share the same customer and project data instead of living in separate spreadsheets or disconnected tools.

Built on: Odoo ERP framework
Industry: Solar PV installers
Core modules: Sales, projects, purchase, inventory, accounting
Accounting export: DATEV, SKR03/SKR04

Use cases

Operations manager at a 25-person solar installer

Situation: Quotes, project schedules and invoices live in separate tools, so the same job shows a different status depending on which system someone checks, and staff re-enter data by hand between them.
How we solve it: PowerOn centralizes the workflow from quote to project to invoice in one modular ERP, so every module reads and writes the same customer and project records.

Owner-operator of a small residential solar company

Situation: Bookkeeping is handled manually and the external tax advisor has to reformat exported data every month before it can be imported into their own DATEV system.
How we solve it: PowerOn accounting exports directly to DATEV format using the SKR03/SKR04 chart of accounts, so the tax advisor receives data in the format their own software already expects.

FAQ

Frequently asked questions

What is PowerOn?

PowerOn is an integrated modular ERP for solar PV installation companies, built on Odoo. It covers the full workflow of a solar installer -- sales, project management, purchasing, inventory and accounting -- in one connected platform instead of separate tools per department.

Is PowerOn built on Odoo?

Yes. PowerOn is built on the Odoo ERP framework and adds modules and configuration tailored to the solar PV installation industry, such as DATEV-ready accounting for German tax advisors and equipment-focused inventory management.

Does PowerOn integrate with DATEV?

Yes. PowerOn accounting exports bookkeeping data directly to DATEV, the accounting software format most German tax advisors work with, using the SKR03 or SKR04 standard chart of accounts. See the dedicated PowerOn accounting with DATEV page for details.

Does PowerOn track solar equipment like panels, inverters and batteries?

Yes. The inventory module tracks stock levels for solar equipment across multiple warehouses, with automatic replenishment suggestions so installation teams do not arrive on site to find the wrong part missing.

Does PowerOn manage installation projects from start to finish?

Yes. The project management module uses Kanban boards, task assignment and time tracking to follow an installation project from site survey through commissioning, tied to the same customer record used for sales and accounting.

Who is PowerOn for?

PowerOn is built for solar PV installation companies of varying sizes -- from owner-operator businesses to installers running multiple crews and warehouses -- that want sales, project, purchasing, inventory and accounting data in one system.
