Good answers here you guys. I'm also having that problem- have a nice carport for my RV, but the sun does hit the front every afternoon. I think I'm going to go the cheap blue tarp route on mine. I also get mid-afternoon sun on the south side, but I think I'm going to just add 2 more lengths of metal down the side.
