PicoPV Test
Pico PV Systems
Currently engagement concerning Pico PV Systems increases. In order to advance the framework for project development in this field EnDev has effected various activities. One of these is a test series for Pico PV Systems. It is divided into three phases:
1. Technical Test I
2. Technical Test II
3. Field Tests
Technical Test I
The technical tests are performed by Fraunhofer Gesellschaft FhG/ISE in Freiburg, Germany. In the first test phase (2007/ 10 - 2008/ 01) eleven systems were tested on road capability with special focus on mechanical stability, lighting characteristics and operability. These systems were in detail:
- 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

Technical Test II
Testkriterien Level 2
| Solarmodul | Werden die Nennwerte von Leistung, Leerlaufspannung und Kurzschlussstrom eingehalten? |
| Batterie | Messung der Kapazität (NiMH+ Pb), Beständigkeit gegen Überladung (NiMH), einfacher Haltbarkeitstest (NiMH) |
| Lichtstrom | Mittelwert über 210 Minuten |
| Brennzeit/autonome Zeit | Leuchtdauer bis der Lichtstrom 70% des nach 15 min gemessenen Wertes erreicht hat (Start mit voll geladener Batterie) |
| Lichtausbeute | Mittelwert über 210 min., Start mit voll geladener Batterie |
| Laderegler | Spannungslevel Ladeschluss-/ Lastabwurfspannung, Eigenverbrauch, Signalisierungen, Schutz vor Entladung durch Modul, Wirkungsgrad |
| Vorschaltgerät | Elektrischer Wirkungsgrad |
| Zyklentest bei CFL-Leuchten | Test der Schaltfestigkeit der Leuchte mit dem Zyklus 60s an 150s aus |
| Simulation | Ermittlung der solaren Deckungsrate für 5 Standorte bei einer Brenndauer von täglich 3,5 Stunden |
Field Test
