20 Year Old System Retrofit

Project Summary

The client visited our retail store, noticed the Franklin battery system, and asked about it. They then hired us to install a full home battery backup system and upgrade their existing solar panels.

Our Approach

We took a two-step approach. First, we installed two Franklin aPower 2 batteries to provide full-property backup during power outages, while also giving the client mobile monitoring of their solar production. Then, after they saw how much their 20-year-old panels had degraded, we upgraded the system with new 450-watt bifacial panels made by CertainTeed. On day one, peak production jumped from 2 kW at noon to 5 kW.

Challenges

The corrugated metal roof was our biggest challenge and the primary cause of delays. It’s difficult to walk on, let alone carry and install panels safely.
