1. The success of solar powered CFL is dominated by the solar panel and battery components and scale with the power output needed.
2. The retail costs of these systems to the end user are often prohibitive. As a result, the potential for these systems has remained highly dependent on subsidy.
3. The local market for solar home systems in Tibet is largely driven by subsidies from the federal government.
4. A consumer market for solar home systems exists in the city of Lhasa, but its sales volume did not appear comparable to the subsidized market.
5. Limitations associated with the current system (1) there is no strong drive for innovation, (2) the end users of the products have little influence on the product design and improvement, and (3) the products are provided free, or at low cost, there may be little incentive for the end users to invest in maintenance of the product.
6. A significant percentage of the solar home systems encountered during the study were non-operational, either due to minor maintenance issues that could not be replaced by local villagers or due to defective products that could not be returned.
