A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

That's the catch. The generation isn't the expensive part. The storage is.
That's the thing, without the Battery it's not cost effective, we'll pay more for the system then it would recover. Our peak usage is at night when the sun is not there.
My utility gives a 50% credit on excess generation. Thing there is the utility is still the one taking responsibility for having the capacity and scalability to respond to variation in demand and production. When I was getting quotes, adding storage would have doubled the cost of the system for a day or two worth of storage. Probably would cost double again to have a system that would keep up through the winter.
Yeah we get nothing from any excess power generation that goes back into the grid. It used to be worth it years and years ago but they stopped because it was costing the energy generators too much.
wouldn’t most people’s peak usage be in the afternoon when the air conditioner is running?
Not with us, after 4pm is our peak usage sun won't be up for much longer
