ONCLUSIONS
It could be found that at Chiang Mai and Ubon
Ratchathani, the maximum annual electricity generation
from the flat-plate solar collectors
were 21.7 and 20.9
MWh, respectively while the evacuated-tube solar
collectors were 28.93 and 28.11 MWh, respectively. The
minimum values of LEC from the flat-plate solar
collectors at Chiang Mai and Ubon Ratchathani were
35.03 and 37.31 Baht/kWh, respectively while the
evacuated-tube solar collectors were 27.07 and 27.28
Baht/kWh, respectively.
