What % overbuild do I need to generate power at night?
- alvah 3y agoClearly a sarcastic question, but as solar panels become vastly cheaper, the battery storage requirements to effectively guarantee power on demand become much less onerous. The kWh of backup required for a solar PV system sized to maximum demand is much more than (e.g.) a PV system sized to 2x maximum demand.
- adrianN 3y agoHydrogen storage has a round trip efficiency of about 40%, so you need less than 2.5 times overbuild.
