While solar power has investors on Wall Street seeing green, countries in the developing world also see a bright future in solar technology.

They believe solar power systems that convert sunlight into electricity can help power developing areas without going the route of dirty coal-fired power plants.

Solar companies like China’s solar panel maker Suntech and California-based eSolar, have recently announced forays into the developing world.

Suntech is teaming up with Pakistan’s alternative energy development board, which the company’s chairman and chief executive Zhengrong Shi called “a clear example of the promise of solar energy.”

Solar thermal company eSolar said last week that it is expanding in Africa and earlier this year it partnered with an Indian company to build solar power plants in India over the next 10 years.
