For anyone who is 'sunlight-challenged', it might be worth considering following the sun throughout the day - especially at either end of the year.Design with wheels on the back and a sturdy handle on the front.You won't regret it.
This is important.Design with sun angle in mind. You want the sun to hit your glass and your pan as close to 90° as you can get. Check a solar panel web site to find the optimal angle for your lattitude.My first design was too flat and did not work well inAug and Sept.
Wax melters and grills both last a lot longer if stored inside during the off season.
My wheels are from an old lawnmower and are pretty good on semi rough terrain
