A city solar-power initiative is taking flight, as solar panels are being installed and operated at junior high schools in Jakarta. The administration has so far installed the panels at two public junior high schools (SMP), 19 and 12, both in South Jakarta. The two are considered pilot projects, and solar energy will be expanded to other schools based on their success.
The principal of SMP 19, Morgan Napitupulu, said that his school had saved up to Rp 8 million (US$686) in last month’s electricity bill. “The school’s monthly electricity bill usually reaches Rp 30 million. The cost this month declined to Rp 22 million,” he said on Wednesday.
Paul Sutanto, the senior engineer of the project’s contractor company PT Alpen Steel, said that there were 145 solar panels installed at the school. “Each solar panel can produce around 145 watt-peak of energy, so there are around 20 kilowatt-peak (kWp) in total,” he said. He explained that 20 kilowatt-peak meant that the solar panel could produce 20,000 watts under clear, sunny skies.

The pilot projects are part of a greater effort by the city administration to reduce the use of fossil fuels in Jakarta.
In October 2011, the administration installed several solar power panels in Thousand Islands regency with a total capacity of 43 kilowatts. The administration also installed 39 solar-powered street lighting systems in several areas of Jakarta in 2010.
