The present study developed a high-performance solar
PV power technology for the LED lighting of a solar home
system. The nMPPO (near-Maximum-Power-Point-
Operation) design is employed in system design to
eliminate MPPT. A feedback control system using pulse
width modulation (PWM) technique was developed for
battery charging control which can increase the charging
capacity by 78%. For high-efficiency lighting, the LED is
directly driven by battery using a PWM discharge control
to eliminate a DC/DC converter. Two solar-powered LED
lighting systems (50W and 100W LED) were built. The
long-term outdoor tests have shown that the loss of load
probability for full-night lighting requirement is zero for
50W LED and 3.6% for 100W LED
