SOLAR

Solar panels and equipment explained

A proposal should identify the actual equipment being offered, not just a generic efficiency claim.

Core system components

Residential systems commonly include modules, inverters, racking, electrical protection, monitoring and sometimes battery storage.

Panel specifications

Compare model numbers, rated output, efficiency, degradation terms and product/performance warranties.

Inverter choices

String inverters, optimizers and microinverters use different architectures. Ask why the proposed design fits your roof and monitoring goals.
