Study and evaluation of energy on the house by standalone photovoltaic systems of half-cell and full cell types

This research aimed to investigate the effectiveness and performance of standalone photovoltaic systems half-cell full-cell types. In Phetchabun province, it requires 8 hours sunlight per day between 8:00 A.M. 4:00 P.M.. Open circuit voltage, short current, DC, AC power are continually recorded for 62 days in July August 2020. According results solar panel efficiency test, full haft cell panels' actual efficiencies 89.13 89.04% manufacturer's maximum power, respectively. The generating types panels was considerably different at 95% confidence. 307.5 307.9 W panels. By using two 345 connected parallel, can produce an average voltage current 25.40 V 21.62 Ah respectively, when charged a 100 24 battery use electrical appliances including 350, 450, 550, 650 W.
