Rooftop solar zero electricity cycle
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
For example, the cost per kilowatt-hour (kWh) for rooftop solar electricity is typically around 8 cents per kWh — less than half the cost of the average utility rate in the US (17 cents per kWh). In other words, going solar gives you control and independence over your electricity rate — something you will never have with a utility.
