For example, to turn on a light at night I have to pull power from the grid.<br /><br />When I installed my system the policy here in Utah was quite generous: 1:1 net metering, so I get billed only if I pull more energy from the grid than I push onto it, with credits for the latter carrying over from one month to the next, but expiring every March.Dan Schroederhttps://www.blogger.com/profile/13437237801383466177noreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-23994216288323620662022-07-05T13:17:55.809-06:002022-07-05T13:17:55.809-06:00Hey Dan, amazing article, I was wondering if you c...Hey Dan, amazing article, I was wondering if you could explain the Electrical Usage section more. I'm curious why your panels are able to produce surplus kwh, yet you still have to pull from the grid. Are you enrolled in an energy buyback program so that you get, more or less, free power from the grid because you produced the surplus and sold it back to them?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-41348120082652918712022-05-12T12:04:56.962-06:002022-05-12T12:04:56.962-06:00Great question!

At some point I intend to do a follow-up post in any case, and at least try to put a bound on any long-term degradation.Dan Schroederhttps://www.blogger.com/profile/13437237801383466177noreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-9058203100724459062022-05-12T11:55:41.296-06:002022-05-12T11:55:41.296-06:00Great stuff - how about a small follow up to see h...Great stuff - how about a small follow up to see how much degradation in the solar cells output over last 6 years?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-62906546059644313672022-01-18T19:42:20.771-07:002022-01-18T19:42:20.771-07:00Thanks Dan!Thanks Dan!Anonymoushttps://www.blogger.com/profile/03235821836461398544noreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-79476361995614757462022-01-18T16:17:13.521-07:002022-01-18T16:17:13.521-07:00Hi Sifat,

I'm not sure exactly what kind of data you're looking for, beyond what's in this article, but you can find daily and hourly generation for my solar panels at https://enlighten.enphaseenergy.com/pv/public_systems/pyng712374.Dan Schroederhttps://www.blogger.com/profile/13437237801383466177noreply@blogger.comtag:blogger.com,1999:blog-1233073253115884208.post-50184841654534070702020-12-19T02:50:00.969-07:002020-12-19T02:50:00.969-07:00Hey Dan, I like your article.

The goal for me is to increase my return of my solar panels. Is it possible to share your solar panel data? I don't have daily data of my solar panels. With this data I could play around to see what kind of setup I want. Thanks in advance.<br /><br />regards<br />Wouter (Belgium)Wouterhttps://www.blogger.com/profile/03530690170908238406noreply@blogger.com
