SM City Bacoor officially switched on what is considered to be the largest solar rooftop in Bacoor City, Cavite (north of the Philippine capital Manila) measuring 6,230 square meters of rooftop space with 3,114 solar panels.

SM and solar solutions provider Green Heat Corp. (Green Heat) said the 1.3-megawatt (MW) rooftop solar-powered facility will help save P10.3 million in annual power bills and reduce its dependence on the national grid, which just reported that it is experiencing insufficient power supply.

“Our group guarantees to provide top quality systems that will perform for many years for our partners, who in turn can expect to make significant savings while making a lasting impact on the environment,” said Glenn Tong, director, Green Heat.

Green Heat accounts for over 40% of the solar rooftop installations in the Philippines, 85% of which are commercial installations, while the rest are residential installations.

The Green Heat-designed system generates a monthly average of 128,000 kilowatt-hours (kWh) of electrical energy, which is enough to power 800 homes consuming an average of 160 kWh a month.

“SM recognizes its impact on the environment and continuously takes measures to prioritize the efficient management of its resources, which in this case is our mall’s vast rooftop space that, aside from its use as shelter, is now a reliable source of power,” said Lorenzo Leon Calingasan IV, AVP for Operations for South 1 Region, SM Supermalls.

For SM City Bacoor, Green Heat used its latest solar technology Zero Export/Smart PV System, which used corrugated GI roof long span and roof-mounted all the solar panels.

Since 2009, Green Heat has installed a total of 14 megawatt-peak solar power rooftops that continue to provide an aggregate of 228 gigawatt-hours. Each rooftop provides a savings return of between 30% and 40%. These installations have also helped reduce about 1,139 metric tonnes of carbon dioxide emissions, which can be the equivalent of planting 1,140 virtual trees.
