Is there an organization representing solar worldwide?

global solar council

Yes, the Global Solar Council (GSC), which was launched in December 2015 during the COP-21 climate negotiations, serves as a unified voice for the solar industry and its supporters. 

The principal members of the organization are national and regional solar associations from both established and emerging markets, including the world's largest markets of Australia, China, Europe, India and other Asian countries, Middle East, South America and the United States.

GSC focuses on conveying the following message to leaders and stakeholders worldwide:

Cost Effectiveness: Solar power is already one of the cheapest forms of electricity globally and prices continue to decline fast. The levelized cost of solar electricity is 80% lower than it was during COP15 in 2009. Solar provides a cost-effective means of fighting climate change today.

Versatility: Solar power is the most versatile form of electricity generation and can be deployed anywhere in the world for the people of developing and developed countries alike. It has great potential for poverty alleviation and rural electrification. Solar also has the highest share of popular support of any electricity technology.

Global Risk: To avoid a greater than 2ºC increase in global temperatures, it is imperative to strongly accelerate the deployment of solar power. A 10% share of global power generation by 2030, from less than 1% today, is certainly possible given the right market conditions.
