For sustainable promotion of solar cookers they must be produced locally. Cookers should be available when awareness has been created. Development programmes should be planned in such a manner that repair and maintenance are easily accessible to users.
Counter Claim:
The development of local production is restricted by: 1. the market is not consumer orientated; 2. a profit motive is unpopular amongst many solar cooking organisations, donors included; 3. little government support is available to manufacturers; and 4. usually small companies or indivuduals are involved. They lack capital and access to credit/soft loans.
