Pico PV Systems have emerged as a strong contender in the solar market of developing countries. Thus,EnDev has developed a test series to test their effectiveness.
Seven solar lanterns reached the second testing stage, of which four are German-made: the Solux LED 100 and Solux LED 50 of the Solux e.V. development assistance project, the Solar 2007-1 by the Freilassing solar promotion project, and the sun x-set mobile produced by Würth. Other lamps of the main test were the Glowstar GS7 of the British company Sollatek, the Aishwarya NEST-6543 of the Indian manufacturer Noble Energy and the Mightylight 3040, also Indian made.
|
Solar module
|
Does the system deliver the nominal rated values of power output, open- circuit voltage and shortcircuit current?
|
Battery
|
Measure of capacity (NiMH+ Pb), persistence against overcharging (NiMH), simple durability test (NiMH)
|
|
Luminous fux
|
average of 210 minutes
|
|
Brennzeit/autonome Zeit
|
The duration is measured until luminous flux falls to 70 % of the initial value. (beginning from a fully-charged battery)
|
Luminous efficacy
|
average is obtained from a period of 210 minutes, beginning from a fully-charged battery.
|
Charge Controller
|
Spannungslevel Ladeschluss-/ Lastabwurfspannung, Eigenverbrauch, Signalisierungen, Schutz vor Entladung durch Modul, Wirkungsgrad
|
Ballast device
|
How good is the efficiency of the ballast?
|
|
Cycle test / degradation of CFL-lamps
|
How long do CFL lamps last when subjected to a switching cycle of ‘on’ for 60 seconds, ‘off’ for 150 seconds?
|
|
Simulation
