I have recently purchased a home with solar panels. The previous owner didn't have a ton of information on them as she inherited the house from her mother who passed away. She has the purchase agreement, but the company that did the installation in 2014 has gone bankrupt (in 2020).
I'd like to somehow figure out how much energy I'm getting out of the panels. I got information from the previous owner on their electric bill, which shows me I won't be paying much. But that doesn't really answer my question about electricity generation.
Looks like I have 14 solar world Mono Black panels with model number 275.
Any advice on how I can go about figuring out exactly how much energy generation I'm getting?
Ancillary Information: the panels are owned outright. They were originally purchased with cash so no loan or lease on them.
Glad to help. I've been investigating my own solar install, so have been digging into the specifics a lot.
Note that the above are the "best case" numbers. Panels can put out less power for lots of reasons. They tend to lose a little bit of efficiency when they get older. Think 1%/year, but that's just a rule of thumb. Being dirty can affect them, cloud cover, angle and position, and hilariously counterintuitively, if they get too much sun. Solar panels get less efficient the hotter they are, so an especially sunny day will lower the power output.
Leads to some complex effort to optimize, but honestly its power that just hits your house for free. That's a fine thing in any circumstance.
