Via South China Morning Post, a look at China's massive 'distributed' solar power generation program on roofs of houses, factories and airports is spreading across country, but curtailment rate is also rising:.
A major push to install rooftop solar panels on Chinese buildings is putting the nation on track for another record-setting year on renewable energy.
Most of that rooftop solar has been added in the past two years, as China offered support for local governments to boost installations, and raised power rates to businesses, making generating their own electricity more attractive.
Fishman, an energy analyst at the Lantau Group, an economic consultancy firm in Shanghai, was keen to meet with developers in Shandong to understand how China is developing extensive rooftop solar installations at such a remarkable pace.
Rooftops and buildings in China fitted with solar panels could match the current global capacity of the entire industry, according to new analysis.
Shandong is leading China's rooftop solar-development initiatives, accounting for 18% of such projects across the country. As of March, the province had installed 33 gigawatts (GW) of distributed solar capacity, enough to power an estimated 18 million homes.
At the same time, the Whole County PV programme provides an opportunity to revitalize rural China, local officials say. For example, homeowners can receive extra income by lending their rooftops to solar developers, or by selling the power generated by their rooftop system, Fishman says. The plan seems to be working.

The versatility of a small solar panel is genuinely incredible. Remember, with solar power; you don't need to spend thousands of pounds on a 10kW system; you can reap the benefits from as little as 10watts of solar power. The sun is a free source of renewable energy, what's not to like?
Illuminate your outdoor area Using a small solar panel to run outside lights is a great way to give you better access to your yard. If it's properly illuminated, you can make use of it in the evenings and even install outdoor kitchens and hot tubs. Solar is great for low powered, gently illuminating lights, which will add to the atmosphere.
This solar energy application has gained a lot of momentum in recent years. As solar panel costs decline and more people become aware of solar energy's financial and environmental benefits, solar electricity is becoming increasingly accessible.
Another solar energy application, especially in the southern and southwestern U.S., is heating swimming pools. The systems circulate water to a collector, where sunlight heats it. The system then pumps the heated water back into the pool.
The portability of a small solar panel makes it suitable for many surprising uses. In this video, a dad uses a solar panel and some other recycled components to turn a stand-up paddleboard into a solar-powered boat. 13. Recharge your electric bike
