Budgets are important. If you can do 1 bit cheap that leaves more budget for better bits you can't make.
Just a simple piece of ply or similar hung in front of the louvre will do it. My Ob leaks so much air in around the bottom that heat would just rise and pour out two louvres. One at either side would also allow the prevailing breeze to push through and carry it out also.
I've found solar powered devices seem to last about a year before the batteries give up.
