I started out with a pair of 45 watt panels and a 15 amp controller, wire and mounts came in a $750 kit in 1994. When a dollar was only worth about twice what it is today. In 1997, I bought another 75 watt solar panel, and maxed out the 15 amp controller.
In 1999, I installed a pair of 120 watt solar panels and a direct TV receiver. This required installing a new controller, and I thought I might install more panels sometime (actually 405 watts was plenty) and bought a 50 amp MPPT controller for $450. They are much lower cost now. I no longer need to tilt my solar panels to fully recharge each day.

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
