Can you help me understand my electric bill and possible solar needs?

Asked by JLeslie (65643points) 1 hour ago

I pulled out an old electrical bill. It says my consumption was 439 for the month. If that is typical, how many solar panels would I likely need? How do I figure it out? I live in a very sunny place, Cdentral Florida, and we can face the panels south, which I assume is the best direction.

How much space do I need to put them on the ground rather than my roof?

What about solar film? I have seen it on the side of buildings on youtube. Is that less expensive than panels? Does the film make as much electricity as panels in the same square feet?

You would be better talking to a dealer, you can tell them your needs and they could calculate how many panels you would need, you do know you need a battery bank, the panels charge the batteries and you draw off the batteries for your needs,and you need enough batteries to take you through the night, when they won’t be charging from the panels.

Lots of things to think about or find out before you go that route. A friend had a dealer come by and the price of the solar panels plus the battery bank would take about 30 years to recoup the money you would spend as opposed to the electric savings. Also, I have heard if you have to get a new roof anytime after solar panels are installed, they have to be reinstalled at a price.
This was from someone who looked a few years ago, so my information may be way off now.
I’d like to hear someone on Fluther that has actual experience.

@chyna is correct. I had them come out and give me an estimate for solar about 2019. Georgia has less direct sun than Florida, which was a factor in the cost.

What made my decision for me was the time to recoup costs – when would the system pay for itself? The solar vendor estimated something like 25 years, depending on energy costs and which controllers I purchased, and whether my local utility would buy excess power.

Heck, I’ll be dead in 25 years. It made no sense for me.
