Average daily solar radiation is 4.09 kWH/m2/day. By
using this radiation 200 WP solar panel produced about 224
kWH per year or 613 Watt Hour per day. Most of aquarium
pump (usually used for hydroponic system is below 50 V. so
that by assuming the inverter and motor is 50%, a 25 watt
aquarium pump was used. But from 1 month observation at
the point, maximum power produced by the system was only
about 380 watt per day. This might happened because of
smoke from forest fires which caused solar radiation
diffused.
