Solar system and 20-kWh battery

Design a plan for the cottage owner to achieve energy independence that includes net metering and 20 kWh of battery power to support critical loads in the event of an outage.

Project Details
Type of home Single-story cottage
Square footage 1,750 sq. ft.
Service entrance 200 amp
Heating Electric
Water heater Electric
Water supply Well and pump
Time needed for installation 2 to 3 weeks
Budget (investment) $55,000
Challenges and accomplishments The main challenge for this project was to maximize sunshine hours. Since the cottage is located in the woods, we had to bring in a tree faller in order to clear some foliage and optimize solar panel usage. The customer’s critical loads are now powered fully and independently by the system.
Equipment installed - 24 400-w solar panels
- 2 6-kW hybrid inverters
- 2 10-kWh batteries
