kW vs kWh in solar & battery storage | Solar Choice
For battery storage Battery capacity is measured (and discussed) in both terms of kW of power and kWh of capacity – this is why you''ll hear talk about ''power batteries'' vs ''energy batteries''. All batteries have both power and energy capacity ratings.
kW vs kWh in solar & battery storage | Solar Choice
Other things to keep in mind when comparing battery capacity. Talking about battery storage capacity can be tricky – especially when it comes to storage capacity, which may degrade over time. Check out our article on why you should always ask for an ''energy throughput'' figure in addition to a storage capacity (or cycle life) specification.
