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.
Indeed, it’s actually Wattpeak. For my work I make a difference between actual Watts and solar Wattpeak. I normally multiply by 0,75 to get the MAX power. This max power only occurs around noon as the sun goes up and down again. For energy in my home (Lithuania) I hope to get in the summer with 1kwh/M2/day from the solar panels.
There are geological overlays graphs available that give indication on how much kWh you can get. Solar atlas is one of them. Look for kWh/kWp, multiply it by your solar installation size and you have your average available intake of energy. You can find the kWh/kWp on average per year,month and day. So you know in winter that you produce a lot less than summer
