Allison Said:

how do you workout power usage to buy solar panels?

We Answered:

60 KWH / DAY? That is 2.5 KW (2500 WATTS) avg. constantly, and most solar panels only produce 40-100 WATTS during peak hours. It would take a lot of panels and panels alone are about $300-$500 each.

Must be something wrong with your usage number, or you have a huge house.

In order to properly calculate your system needs, you need to look at not only averages, but your peaks if you plan to go completely solar. If you just want to supplement and lower your grid usage, then just buy all you can afford. You will probably never save enough to pay back unless you have great subsidies, but you will feel good because you did cut CO2 emissions.

Solar power panels?

We Answered:

They may be connected and running, but you just can't see the cables because they are concealed. Of they may not even be electric. They may be solar water heaters that have water lines running inside a black box.

Did your mom purchase the house with them on there? If so, can she contact the previous owner to learn who installed them and why?

In the absence of any meaningful information, I would suggest that you call a solar company in your area and have them come out to tell you what it is that you have.
