I've googled and looked at all the normal online retailers and it seems that 10 panels is the minimum unless you want to pay absurd prices for panels.
Can anyone point me in the right direction?
I live in NJ if that helps.
I've Used A1 Solar Store. They're basically a clearing house that works with local distribution centers. They are associated with distro centers all over the USA.
I bought four Trina 360W through them, then drove 40 miles to pick them up from a massive third-party truck depot. They do not ship to customers.
The experience seemed on the surface to be "sketchy", but I got my panels, and they are brand new and in excellent shape.
I picked up six used 370W solar panels for $900 off of Marketplace not too long ago and they had many more.
They likely would've individually sold them too if I had only needed one.
I had to drive over an hour though.
Still worth it.
