SOLAR STORAGE
FOR A COMPLETE SOLAR SYSTEM
*Outback Power, Batteries & Indoor Enclosure Battery Rack
SOLAR + BATTERIES
THE MARRIAGE OF NEED AND LOGIC
• Grid-Hybrid design for new system installation
• AC Coupling design for existing solar projects
• Attach batteries to their own separate "critical load" sub-panel or back-up the entire main distribution panel with storage
• Charge batteries from solar panels when production is in excess
• Charge batteries at night during "Super-Off-Peak" utility hours for the lowest $/watt charges
• Continue to expand your battery bank for additional storage
2 MAJOR REASONS
TO ADD BATTERIES TO SOLAR
1. Main service disconnections shut down solar production.
Grid-tied solar systems are tied into the main service electrical panel through a "back-feed" solar breaker. This over-current device is sized based on the size of the array. The solar breaker is another source of electricity feed into the electrical panel, but operates as any other breaker would when the utility feed gets cut in a blackout - it stops working.
"So you're saying I just purchased tens of thousands of dollars of solar for my home and I still can't use it during a power outage, even when the sun is shining?" Yes.
However, by incorporating a battery bank, you avoid this problem and insure your solar investment. When grid power is lost, your solar can charge your batteries and your batteries will power your home.
2. Solar systems often produce more electricity than is consumed.
The average homeowner will only use their rooftop solar system to ~70% of its true capacity (SEIA, 2016). This is because their needs are already being met by what the solar is producing. However, what happens to that additional 30% of solar electricity? It is usually "net-metered" which means the utility puts in place a plan to buy back your excess energy. The downside of net-metering is that 1.) you still have to buy back electricity from the utility at night even though you just sold them some during the day and 2.) these programs are becoming highly regulated, and even eliminated, all over the United States due to utility companies loosing potential revenue.
The better option? Bank your excess energy. That extra 30% of electricity that you generated throughout the day on your already purchased solar system can be stored in battery reserves for when the sun stops shining.
Solar + Batteries. The logical next step for the educated consumer.
