Solar Panel Array ( 6 panels)  1950 watts
This is a project I designed and installed in 2017. It consists of 6 Suniva mono-crystalline solar panels built in Saginaw, Michigan.... some of the last made in the USA. I built it to be supported on 4 posts in the ground next to the barn and with a bracing structure attached to the barn. I did not want it on the roof. It is manually adjustable in the North-South direction from 20 degrees ( summer) to 62 degrees ( winter). The system is Grid -Tied meaning that no controller or batteries are needed. Each panel has it's own inverter so the power coming out is 220V AC, This way you can use smaller wire and tie it right into a breaker in the barn and it supplies power everywhere as long the sun is out. It has a disconnect switch that I use if the power goes out and I need to turn on the generator. The system is safe in case or a power outage in that the inverters shut off if they do not see 60 cycle power  on the line. I disconnect them when the generator is on because they can burn out a generator if both are operating. The frame is made with Unistrut channels and all fasteners are stainless steel and the aluminum panel clamping blocks and pivots are all custom made..........................Cheers, Jim
Looks like a great system.  
Well Done, Jim. an having the disconnect is required in the event that a line crew is working on the system down stream of you.

Was looking to do something like this years ago but gave up on it, couldn't find the solar panels around and when I found them elsewhere the shipping was too much. Nice project !!!   Mike
Hi Mel. Try Solar Biz in new Mexico. I bought from them and the panels came from a Wisconsin warehouse. I'll bet the prices are way up today. Mine will be paid back in about 8 years. With just 6 panels, I make about 30% of my power every month. I did not want to make over 100%, then they'll want me to sign a contract!
