Quality of PicoPV Systems
More than 100 firms are offering PicoPV products in developing countries today, but most products are of very low quality, with serious implications for consumer trust in the new technology.
Early lab tests have focused the awareness of governments and donors on the importance of quality control and customer information – however, field tests in sufficient countries with sufficient sample sizes are needed for a better understanding of PicoPV performance under real-life conditions, and to identify gaps in the emerging draft lab test procedures. In addition, private sector actors lack basic market information on this new technology (such as national market potentials, local consumer preferences and willingness to pay) which they would need to decide if and how to enter this new market segment.
To sum it up, experience in development cooperation generally shows that one thing must be avoided at the outset: that users of cheap and inadequate devices should become so disillusioned that the entire technology is discredited.
Therefore, quality control is one of the most urgent tasks. This could be achieved via a simple, two- pronged approach:
- cooperation between test labs, institutes and universities to apply the simple testing procedures developed by Fraunhofer institute with funding from GIZ and WBG,and
- national awareness campaigns for PicoPV among private and public sector, as well as future users. 
Already accomplished Laboratory Tests in order to evaluate the PicoPV systems are as follows:
After a comprehensive screening of the global PicoPV products market in 2008, a pre-selection of promising lamp models were taken for a lab test (developed jointly by Fraunhofer Institute for Solar Energy Systems (ISE) Freiburg, Germany, and GIZ in order to identify a set of lamp models that meet minimum quality standards.
The lamp models that passed the lab test were taken for field tests in different developing countries.
The Uganda data highlight the urgent need to introduce quality labeling mechanisms, based on proven test procedures, on international as well as local levels: Almost all lamp models, including top-end products with high quality claims by manufacturers, did not meet expectations in terms of durability and robustness – in spite of the fact that they had been picked as “best of class” in the previous lab test (which in turn was based on the lab test draft methodology currently in use by GIZ as well as World Bank’s Lighting Africa).
Therefore, in general, the field test has underpinned that in order to come to valid conclusions regarding aptness of technical lamp design and robustness, lab testing does need to be complemented through long-term testing under real-life conditions. The field test has shed light on certain technical strengths and weaknesses of some lamp models that were beyond the scope of what could be assessed by the lab test methodology developed by Fraunhofer Institute for Solar Energy Systems for GIZ.
