= Overview =

Pico PV Systems have emerged as a strong contender in the solar market of developing countries. Thus,[[Energising_Development_(EnDev)|EnDev]] has developed a test series to test their effectiveness.<br/>

== Technical Test I<br/> ==

The technical tests are performed by '''Fraunhofer Gesellschaft ([http://www.ise.fraunhofer.de/en?set_language=en FhG/ISE])''' in Freiburg, Germany. In the first test phase (2007/ 10 - 2008/ 01) twelve systems were tested on road capability with special focus on mechanical stability, lighting characteristics and operability.

<u>These systems were in detail:</u>

*GL9000SW, Global Marketing Technologies Inc. (US) --> overall picture bad
*MS01, Macro-Solar Technology Co,. Ltd (China) --> overall picture very bad
*Solar 2007-1, Solarprojekt-Freilassing e.v. (Germany) --> overall picture good
*Mightylight, Cosmos Ignite Innovations (India) --> overall picture good
*AISHWARYA, Noble energy Solar Technologies Ltd. (?) --> overall picture middle
*Solar Home System, "Afghanistan" --> overall picture very bad
*2212SL Wuara, SolEnergy Africa (PTY) Ltd (South Africa) --> overall picture very bad
*SOLUX-LED-100, SOLUX e.v. (Germany) --> overall picture middle
*Sun x-set mobile, Würth Solergy (Germany) --> overall picture middle - bad
*Glowstar GS7, Sollatek Ltd. (UK) --> overall picture middle
*AS018, Astral Solar technology Co. (China) --> overall picture bad
*SOLUX-LED-50, SOLUX e.v. (Germany) --> overall picture middle

<br/>

== Technical Test II<br/> ==

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.

<u>In the following table you find a selection of the most important criteria:</u>

'''Testcriteria Level 2'''

Does the system deliver the nominal rated values of power output, open- circuit voltage and shortcircuit current?

|-
| <div class="draft"></div>Battery<br/>
| 
Measure of capacity (NiMH+ Pb), persistence against overcharging (NiMH), simple durability test (NiMH)<span style="font-size: 11pt;  font-family: arial"></span>

|-
| 
Luminous fux<span style="font-size: 11pt;  font-family: arial"></span>

| 
average of 210 minutes

|-
| 
Brennzeit/autonome Zeit

| 
The duration is measured until luminous flux falls to 70&nbsp;% of the initial value. (beginning from a fully-charged battery)

|-
| Luminous efficacy<br/>
| 
average is obtained from a period of 210 minutes, beginning from a fully-charged battery.

|-
| Charge Controller<br/>
| 
Spannungslevel Ladeschluss-/ Lastabwurfspannung, Eigenverbrauch, Signalisierungen, Schutz vor Entladung durch Modul, Wirkungsgrad

|-
| Ballast device<br/>
| 
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?

|-
|
