TLDR: As a minimum, aim for battery storage equal to 25% of your daily usage, plus 2 kWh for backup. So if you use 20 kWh a day, don’t go smaller than a 7 kWh battery. It probably won’t last all night, but it’ll usually cover the expensive evening peak. How Much Battery Storage Do You Need? [pdf]

This paper presents field results and analyses quantifying the ability and the value of Sodium Sulfur (NAS) battery energy storage toward shifting wind generation from off-peak to on-peak, limiting the ramp rate of wind farm output, and a strategy to integrate the aforementioned goals. [pdf]
[FAQS about Sodium battery energy storage wind power]
Batteries can provide highly sustainable wind and solar energy storage for commercial, residential and community-based installations. Solar and wind facilities use the energy stored in batteries to reduce power fluctuations and increase reliability to deliver on-demand power. [pdf]
[FAQS about Wind and solar lithium battery energy storage]
Standard warranties for lithium-ion batteries covering both performance and defects are two years, but extended warranties can be purchased. A warranty beyond 10 years does not make sense because so much of the battery would need to be replaced after year 10. Insurance can also be purchased. [pdf]
