Scooterman, the south west side would be fine. The panels are about 40" by about 60" so however many would fit. Of course the more you install, the more cost effective it is because the labor is not that much to install more panels. I completed the entire job myself in 4 days.
I am getting about half of the money back from the power company and $5,000.00 from the statre and federal in my income taxes.
It is fairly sunny now and it is generating 1600 watts. The most mine generated when I was looking was just over 2300 watts. The max is 4,000 watts but I don't think that would happen in NY. The power company is coming to put in a different meter that spins in reverse should I generate more than I am using. I don't think that will happen because of my tank and three large refrigerators. But I do have (and sell) power cost meters and sometimes my cost for power goes down to 3 cents an hour. The system is supposed to save me $900.00 a year but I won't know that until next year.
The inverter is 4,000 watts and it is connected to a 30 amp two pole breaker in my panel.
The wiring is simple. The panels come with 2 plugs, you just plug them into each other then take the wires down to the inverter.
I changed my roof before I installed the panels because I installed my existing roof 30 years ago. The panels are warrented for 25 years. The panels are easy to come off. They justr snal in but to change the roof. I would have to remove all the panels and the supporting rails, about 2 days work. It's not the end of the world but I would not put them on an old roof.
I would recommend it to anyone but it is a large initial cash layout which you don't get back for about 90 days and the rest with your taxes.
It will definately increase the saleability of the house and reduce the energy costs.
It will also make your roof last longer because no sunlight touches the roof under the panels.
As energy costs rise I think you will see more and more of these systems. Unfortunately, the rebates are going down. That may change with a new administration.
