There is no question it can be logistically harder, but trained installers and a steady flow of energy technologies (which a number of nations now have) make solar hot water, PV, and even small wind energy workable. We have found that a very important place to start is on product quality, standards, and certification. In a series of papers we have examined the Kenyan industry, e.g: Jacobson, A. and Kammen, D. M. (2007) “Engineering, Institutions, and the Public Interest: Evaluating Product Quality in the Kenyan Solar Photovoltaics Industry”, Energy Policy, 35, 2960 - 2968. Duke, Richard. D, Jacobson, Arne, and Daniel M. Kammen (2002) “Product quality in the Kenyan solar home industry”, Energy Policy, 30 (6), 477-499. we have been charting the progress of this industry, that is now quite mature. While there are ups and downs in quality, a diversity of companies goes a long way to keeping check on each other and weeding out the bad actors that always creep in. The Kenyan government has done a very good job, too, in writing white papers (official government assessments) and in working to set standards where needed. Vigilance is needed, and that is always a challenge, though.
