First off, thanks all for the information I have gleaned from this and other sites. I am truly fascinated by the use of this idea. I started off collecting cans, and midstream decided to switch to a screen collector. My Friends and family are still piling cans at my feet so...Seemed easier for me with better results for my first try. I live in Racine Wi (around Milwaukee) and obviously its pretty cold in this area. I wanted to try and help out the heat in my workshop. Because of a giant pine tree in my yard I lose the sun around 2pm I may cut that tree down in the future. But for now, I will just live with it. I start making heat around 930 in the morning and it continues till just about 2 (January) I know this will change for the better as the days get longer

I wired in a Duct fan booster, with a snap switch, and also an auxiliary receptacle, that I use for now to power a light I can see from the house if I am not out there. Just to kinda see when it is turning on and off. For the last 3 weeks of use I have gotten pretty comfortable figuring out by feel when it will be on. I will probably disconnect the the light today or tomorrow

In my shops position the window that I have the light in faces east. I notice that I get some very nice sun there early in the morning. I am currently thinking about building 2 collectors that will mount inside the shop to those windows. I am planning on doing one with cans and one with screen to be able to compare efficiency. (can anyone tell me if a collector box mounted inside needs to have insulation? or can it just be plywood painted black)
