Solar electricity every hour of every day is here and it changes everything

Key insights:

“Batteries are now cheap enough to unleash solar’s full potential, getting as close as 97% of the way to delivering constant electricity supply 24 hours across 365 days cost-effectively in the sunniest places.”

“On an average day in a sunny city like Las Vegas, US, providing 1 kW of stable, round-the-clock power requires 5 kW of fixed solar panels paired with a 17 kWh battery. This combination can deliver a constant 1 kW of solar electricity every hour over a full 24-hour period – and this amount of battery will be sufficient for most regions across the world.”

“Achieving 97% of the way to 24/365 solar in very sunny regions is now affordable at as low as $104/MWh, cheaper than coal and nuclear and 22% less than a year earlier.”
