You can use a painter's plastic tarp ... it's not clear, but it will allow light to pass through. I get it on a roll...and it lasts for half of forever. I put it on the north and west sides of the run in winter to cut the "breeze". ;)

But being at the beginning of that magical journey all women must take, these 90 degree days are just about to cause me to burst into flames...LOL!!!! I am looking forward to some snow. :D
