Electricity is cheap in Georgia.  To run up a $450 bill, you have to be using an absolutely insane amount of electricity, at least 3000-5000 kWh per month.  In GA, you get about 4 hours of peak-equivalent sun exposure per day, and that's for optimally placed and angled panels.  With a typical 3-5 kW system, you will generate maybe 10-20 kWh per day if you are lucky.  That would be enough to knock your power bill down by maybe $45 to $90 a month, depending on sun exposure and your electric rate.  If you wanted to make $400 of electricity per month, you would need something like a 30 kW system -- roughly 100 panels.  That would be quite the array, and would probably cost more than your house.

If the panels are mounted on a building, they are probably not angled ideally, so that would further reduce the output.  Shade of course will completely kill the array, I have no idea why you allowed them to install the panels in this way.  I am guessing the house is positioned in such a way that it was impossible to install the panels facing south at the correct angle.  If they are facing the wrong way, the output will basically be zero.  The way our eyes perceive brightness, what looks like a small drop in intensity can be a 90% reduction in power.

Solar often doesn't even make sense in California, where electric rates are something like 40 cents a kWh and there is way more sun.  It definitely won't make any sense in Georgia, your electric rates are 10-12 cents a kWh. That's why solar systems are sold by shady companies using timeshare sales tactics, and why utilities aren't building giant solar farms unless the government pays for it.

You would be far better off figuring out how you are managing to use so much electricity.  I'm guessing it's a combination of very poor insulation, inefficient HVAC equipment, and keeping the house at meat locker temperatures all summer.  Get an energy audit, that should have been the first step before plunking down money for a solar system.

We received the same offer from Amex. The offer details state: You may not receive the statement credit if the merchant uses a third-party to process or submit your transaction.
 
PayPal is a third-party processor. Amex stood behind its policy; you simply didn't like, read or understand the terms

 You DID NOT follow the terms of the offer! Security...my a#@! You involved a THIRD PARTY thus opening the door for fraud. You avoid credit card fraud by checking your statement every time it comes out to see if it is correct and if something is there which shouldn't be there, you alert them immediately. However, given the sorry state of this society, you're probably one of those who never checks their statement, never keeps written records of any checking accounts and never balances their checking accounts! NOTHING has changed in retail. If you want to pay a bill by credit card, you do it directly WITHOUT involving some useless third party. Let me save you some effort....I'll tell you ahead of time I don't work for them!
