Out of curiosity, is anyone actually keeping track of the actual amount of electricity they get out of these units on a daily basis and maybe keeping a web site with a graph showing how the performance varies each day so you can see how it does summer vs. winter, sunny vs. “lake effect” and such.
All factors should be included. Including the daily electricity consumption from “the grid”.
The library has a subscription to “Home Power” Magazine
www.homepower.com and the solar systems seem extremely complicated. Requiring a LOT of maintenance.
The “daily track keeping” should also include maintenance, trouble shooting, washing the collectors, and “shoveling” or otherwise removing snow and ice.
It would make an excellent science project for the school kids of all ages and grades. For generous extra credit.
