solar panels for electricity

[Michinori Kaneko]

Has anyone installed solar panels on their investment properties? I've looked into this per someone's suggestion, and looks like there are some federal grants and loans that allows you to install, and also if the panel generates more $ than your property consumes you get credit (or payment) from the utility company on the excess electricity. You also get tax deductions on installation and the assessed value of the property cant include the value of the panels. so there are many benefits to it, but i'm just trying to figure out if savings/cost has been a beneficial return for anyone who has done this. Thank you.
