Our solar panels came with our (resale) house and were a requirement for us on any new home we built or purchased. We own these; they are not leased. We live in AZ where summer AC/electric bills were close to $500/month in our old non-solar house. Averaged annually, our monthly electric bill is about $70/month, a huge savings from our previous home. As others have posted above, do your own research and don’t fall for anything that just appears on your doorstep.
