A summer power chart shared online has Massachusetts solar users marveling at just how much rooftop generation may now be helping the grid.
Even after quick corrections from fellow Redditors, the takeaway remained striking: Small home systems across New England appear to be adding up in a big way.
What's happening?
Commenters quickly noted that the chart under discussion appeared to cover the entire New England region, not just Massachusetts.
The image, drawn from ISO to Go demand data, had led the original poster to ask whether it showed that "almost 25% of the electricity used during the day at the peak came from home solar panels."
The poster later conceded, "This may be all of New England. I'm not used to reading the data."
Another user had also explained, "The solar is the area between the curves not all 24gw."
The OP added, "It's still amazing to me that we have 5gw production in New England."
The thread also filled up with individual reports of daily generation.

One user in Connecticut said, "I produced 65.4 kWh yesterday in CT and used 72.3 kWh," while a commenter from Cape Cod wrote, "I produced 44kwh yesterday from cape cod / Used 30kwh -more credits / That's with 3 mini splits on all day."
Why does it matter?
If rooftop solar is really helping to cover that much daytime demand, it could matter for both grid reliability and household budgets.
Electricity use often spikes on hot, sunny afternoons — the same time solar panels are typically generating the most power.

More rooftop solar can also help reduce the need for electricity generated by polluting fuels during peak demand hours.
That can ease strain on the grid, reduce planet-warming pollution, and make extreme summer heat a little less expensive for families that produce some of their own power.
