Three types of coverage to look for in your proposal
| Component | What to identify | Useful document |
|---|---|---|
| Panels | Product warranty, any performance warranty, manufacturer conditions and exclusions. | Technical data sheet and warranty certificate for the selected modules. |
| Inverter | Duration, equipment coverage and repair or replacement terms. | Model reference, serial number and manufacturer conditions. |
| Installation | Scope of installation work and conditions for visits after commissioning. | Quote, invoice and handover documents. |
Durations depend on the equipment and services selected. Your quote states the references and terms applicable to your project. Any optional warranty extensions are shown separately.
Product warranty and performance warranty
The product warranty covers equipment under the manufacturer's conditions. A performance warranty describes a module's power level over time under defined conditions. Your rooftop system's generation also depends on sunlight, layout and operation.
Keep the panel and inverter references together with the installation documents to compare your project. This traceability makes post-commissioning support easier.
What is monitored during operation
- Generation: checking readings or the monitoring interface, where fitted.
- Module condition: dirt, new shading and visual observations reported to the team.
- Electrical equipment: checks arranged according to recommendations and the selected contract.
- Mounting structure: checking fixings and the visible condition of supports during visits.
Cleaning and maintenance frequency depends on the site: dust, surroundings, roof access and agricultural or industrial environment. We specify services and frequency in the maintenance proposal.
Contact after-sales support with the useful details
Provide your name, installation location, inverter model and what you have noticed. An error message, start date or generation reading helps guide diagnosis.

Plan ongoing support at the quote stage
Ask for clear warranties, maintenance services, travel conditions and handover documents. This gives you a complete view of the initial cost and ongoing support for your installation.
