How to read solar power today
Solar output follows daylight, weather and the season. It is usually strongest around the middle of bright days and can be near zero overnight.
Because much solar generation is embedded in distribution networks, measured grid demand can also fall when rooftop and local solar are strong.
Recent solar context
Highest average solar output was about 3.4 GW on Saturday 26 September. The latest settled daily summary says: Archived daily context (2026-09-28): Monday 28 September, measured average generation was about 26.8 GW. Renewables averaged 26.8% of measured generation, gas averaged 11.8 GW, wind averaged 3.6 GW and solar averaged 2.7 GW.
Use solar alongside wind, demand and gas generation rather than reading it as a standalone cleanliness signal.
FAQs
Why is solar low at night?
Solar generation depends on daylight, so live solar values are normally very low or zero overnight.
Can solar lower carbon intensity?
Yes. Solar can lower carbon intensity when it displaces fossil generation, especially during bright lower-demand periods.
