Pursue a manufacturer installer-certification program to maintain warranty eligibility for a specific solar or storage product line

Steps

1. Identify which manufacturer certification programs are relevant to the products being installed by checking the manufacturer's own installer-training pages (e.g., a battery manufacturer's certified-installer program or an inverter/microinverter manufacturer's installer network)
2. Confirm current prerequisites for the specific certification level (e.g., passing a product-specific installer exam at a defined minimum score) directly on the manufacturer's site before enrolling, since exam content and pass thresholds are updated with new product generations
3. Complete the manufacturer's required training modules and pass the associated exam(s) for each product generation being installed, since certification is often tied to a specific hardware version
4. Confirm what warranty terms are actually contingent on installer certification by reading the manufacturer's current warranty document (not marketing pages), since some warranty provisions only apply, or apply at full value, when installed by a certified installer
5. Track re-certification or recurring training requirements tied to new product releases so the certification doesn't lapse for newer equipment versions
