A zero thermal efficiency results at any time that the
collector cannot produce any useful thermal energy. Efficiency is
defined in Type563's case as the energy produced divided by the
energy input (mainly indicent solar). If the collector is not
producing any useful thermal energy (because the sun is down) then
the efficiency is zero.
kind regards,

Dear all,I used a type 563 PVT tool for my simple simulation.What would be the possible reason for a zero thermal efficiency output in the attached program file?Please have a look.ThanksJibi
