solar thermal panels can economically recharge

Hello,

I've read that the solar thermal panels can economically recharge the ground. For example, if the entering water is 35 Deg F. and the outside is sunny and 50F, solar thermal will contribute to the heating. Claims include the hybrid system has a lower life-cycle cost. To check on the economics of this hybrid arrangement, how does one size thermal solar system? Key parameters should be KWH / SF, Panel Efficiency (to heat water), flow rates, etc.

How can I fix a solar water heating leak?

Hello

we have noticed over the last few weeks the hot water is not as hot as it should be. So I went up and unscrewed the release valve and put about two liters of antifreeze in to the system. Then I noticed a small puddle on the roof at the corner of the panel. Iit's leaking very slowly . Has anyone tried to fix a leak like this with one of the chemical additives and did it work or have I got to go and order a new panel. This one is maybe 12 years old.

Thanks!
