People seem to get all worked up over efficiencies, when the energy is free so really do you care if your water is 140F or 142F??? Most often changes in contruction like double pane or polycarb or riser vs serpentine just create more labor and more cost..which equals more time before you break even if you are looking at it solely from a $ point of view...if you can find a peice of glass 2x2 you can build a panel for around $15..copper on aluminum fin and start saving money.peace
