 Occurence rate of technical problems (10% to 50%) during a field test in Uganda confirm this statement. Furthermore, 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 [[Solar Laterns Test|GIZ]] as well as [[Lighting Africa Outstanding Products|World Bank’s Lighting Africa]]). Particular technical improvements concluded from the Ugandan field tests are: manufacturers need to improve products’ solar fraction, equip lamps only with advanced charge controllers, and work on the robustness of the products, and of the connection parts in particular. Problems were: frequent deep-discharge of batteries, low battery life-spans and overall unsatisfactory lighting service were the frequently observed. Apart from that, the components that most often caused lamps to fail were cables, plugs, input jacks and switches. These parts are obviously under extreme stress when lamps are in everyday use by extended families with several children, and when modules are put down for charging on the ground in the courtyard (while lamps are kept inside to protect them against thieves). <ref name="ii">GTZ, iidevelopment. 2010.

 From GIZ experiences in Tanzania, it has been observed that customers prefer to have a switch installed in the house rather than a portable system. Even if it provides only very basic services, there was a preference for small solar home systems at least if they are affordable. Furthermore, a disadvantage of portable systems has been that they can be stolen easily in comparison to a fixed system in the house. A crucial point has also been the recharging of solar lanterns. As they are usually placed outside and oriented to the sun in the morning and remain in the same position throughout the day, the full charging potential cannot be achieved.
