The solar powered aeroponic system was developed for cultivation of high valued crops. The aeroponic system was developed by using different components like SPV (Solar Photovoltaic) module, growth chamber, mister, nutrient tank, D.C pump, battery and digital timer. The system comprising a 120 W SPV module with 84 W D.C motor pump, main, submain, laterals and misters. The mister discharge, pump discharge, current, voltage, pump pressure and discharge of misters were tested. The mister with discharge of 7.2 lph in the pressure range was 3.8 kg cm-2 provided by the pump. The mister spraying radius and spraying height were found to be 40 cm and 45 cm respectively. The maximum and minimum weekly relative humidity recorded inside the growth chamber were 88.1 and 84.4% at 7th and 2nd week respectively. Similarly, the maximum and minimum weekly relative humidity recorded outside the growth chamber were 70.4 and 58.3% at 2nd and 7th week respectively. The maximum and minimum weekly temperatures recorded inside the growth chamber were 21.5ºC and 18.3ºC at 3rd and 4th week respectively. Similarly, the maximum and minimum weekly temperatures recorded outside the growth chamber were 31.1ºC and 27.4ºC at 7th and 2nd week respectively during experimental period (June - August 2019). Total cost of the developed aeroponic system for 4 m2 area was Rs. 30,000 including accessories.
