This is a cooler that uses a simple micro irrigation (sprinkler) system to cool the solar PV panels on my roof. It uses a Picaxe microcontroller and temperature sensors to control the cooling so only the minimum amount of cooling is used. The microcontroller is configured to start the cooling cycle whenever the panels reach 8 degrees above ambient. This increases power output by around 20%. The cooling is based on evaporation- almost no water drips off the panels.
HUAINAN CITY, CHINA — A new floating solar farm constructed on a lake in Huainan City, China is said to be the largest in the world.
According to the South China Morning Post, the farm is made up of 160,000 solar panels. These panels reportedly can produce electricity for up to 15,000 homes.
The farm is built over a lake that emerged from a collapsed coal mine, reported Phys.org.
The water from the lake helps cool the panels’ electronics, reported the Smithsonian Mag, citing a Telegraph report on Europe’s largest solar farm.
The farm was linked to Huainan City’s power grid last month, reported the South China Morning Post.
