Hey all, you’re an intelligent crowd so wanted to give a heads-up on a recent solar development - Sunlight Backup. This is new and really takes grid tie solar-only installs to where they’ve always needed to be. Enphase offers this now. Other manufacturers will no doubt be following suit depending on patents and such.
Grid-tie solar panels without backup batteries have always stopped producing when the grid goes down as a safety measure so solar installs don’t put power out on the grid to electrocute linemen and women. Enphase is now making solar components that will give you full solar array power when the sun is on them while isolating you from the grid. It’s like having a backup generator that runs during the day and you don’t need to buy gas for. It’s just without a battery you lose power as the sun goes down - but it’s plenty of juice to keep fridges and freezers cold, charge other batteries during the day (see bluetti.com and ecoflow.com) Next day, you get power again.
I just missed this development myself and installed a solar system with battery backup. Cost a lot of extra money for that battery, too. I’ll have power through the night but the new system that can do backup solar would have been all I really needed and much less expensive. In an extended outage, power every day would be like manna. Ask Texas about how nice to have emergency power. They are headed into a very hot summer with their isolated grid and just lost six generating stations.
Now you can get all the advantages of solar, help with climate change, etc, and get a backup power system at the same time. Some may even consider these kinds of systems for off-grid or remote use. But in an extended blackout, you will still have power available when the sun is shining. Until now, that was the luxury of gas generators and battery-backed solar. Now straight solar installs can do it too.
Anyway, just an FYI. Solar is very reasonably priced now. You can get systems that pay for themselves in 10-15 years, finance where it just looks like the electric bill to your wallet, and now get full daytime emergency/backup power. That’s huge.
And as an aside, watching your meter run backwards is kind of a thrill… 👍😁
