Solar System Procurement: Comparing Panels, Inverters, Batteries and Installers

Compare system design, component evidence, warranties, generation assumptions, installation scope, monitoring and after-sales support.

Start with the load and objective

Backup, bill reduction and off-grid operation require different system architectures.

Compare component evidence

Review model numbers, datasheets, certification, warranty issuer and local service capability.

Check the complete installation scope

Include structure, cabling, protection, earthing, monitoring, testing and approvals.

Verify performance assumptions

Generation estimates should state orientation, shading, losses and operating conditions.
