 Solar lanterns could replace environmentally damaging kerosene lamps in many developing countries and supply high quality light to a large proportion of poor households. To meet this end, the products must be well-made and priced within the reach of the poorest. The lab test implemented by GIZ and Fraunhofer ISE in 2008 and 2009 shows that there are too few solar lanterns that meet both criteria.

 The quality of solar lanterns on the market is mixed, and prices are still too high for them to sell in great numbers in view of the low saving rates of poor households. However, we expect prices to drop below 50% of 2008 values over the next few years. As they offer higher quality lighting, better handling, environmental advantages and sometimes radio or mobile phone charging, massive market growth can be expected in the near future. In light of the mixed test results, informing potential consumers about lantern quality will be of great importance for a healthy market development.<ref name="GIZ09">GIZ. 2009.

 In the initial Test Level 1, ISE examined all twelve systems for quality of workmanship. Five lamps did not pass test level one. In general the tests show that a majority of the available lights are not suitable for “Off-Grid Lighting” ion developing countries due to their very poor quality, which would lead to very short lifetimes and bad lighting service for poor rural customers.<ref name="ii">_</ref>
