| Abstract |
The use of Maximum Power Point Tracking (MPPT)
has a potential for increasing the energy yield from photovoltaic
panels. The DC-DC-converter efficiency, no-load power
consumption and panel temperature are important in this
respect. Three test circuit charge controllers with MPPT are
built. The energy yield using MPPT is compared to simply
direct connection to a battery, using two months measurements
from two photovoltaic panels. The calculated energy gain is
6.4% for the measured conditions. This is so low that the main
reason for choosing a charge controller with MPPT should be
added values of a switch-mode converter such as reduced
weight, regulated output voltage or battery cell voltage
balancing. |
