What You Need to Know

Description:

The system consists of 15 Panasonic panels with a total rating of 4.95kW DC paired with a 9.8KWh LG-Chem battery to maximize self consumption (i.e. try and make total imported power zero). Scroll through pictures above for screenshots of spreadsheet data.

Other Benefits:

The battery helps lower power imported from the grid thereby reducing the impact of NBC (non-bypassable charges).

Advice:

Get quotes from multiple installers. As a general rule, you will pay more for the same system if you go with the big name installers.

Experience with Installer:

The installer I went with already had the LG battery in their warehouse. This was the single biggest reason I went with them.
