I was wondering if someone knows what should the Solar Fraction for the coldest month in a year be, for solar space heating?
I found on a number of places, that an an annual one should be 70-80%.
But I would like to know how much would the one for the coldest month in a year be?
100% for Mediterranean climates?
Thank you for the reply.
