HDB Raises Solar Goal for 2030 to 540mwp

“This is part of this new national solar target to work towards at least 2GWp from 2030, as announced in October 2019 from the authorities,” said HDB at a release on Monday (30 December).

It noticed that the new 540 MWp target could generate 648 GWh of clean energy annually, which is sufficient to power around 135,000 four-room flats and reduce carbon emissions by 324,000 tonnes each year.

“In comparison, this could increase clean energy generation by 145% in the last target,” it said.

HDB explained that it’s able to make bolder strides in harnessing solar power as advances in PV technology enabled them to generate more solar energy in precisely the same amount of space on HDB rooftops.

Monocrystalline Passivated Emitter and Rear Cell panels, for instance, are more popular than polycrystalline panels as they can covert about 20 percent of sun into electricity. The latter can convert just about 16%.

For this, a number of those formerly unsuitable rooftop spaces, such as point cubes and partially shaded areas, can currently be installed with solar panels.

About 2,500 longer HDB blocks are in the progress of being installed with solar panels will start installation shortly.

The solar power is used to power the cubes’ lifts, lights and water pumps. On average, these HDB blocks achieve net-zero energy intake within shared areas. Excessive solar power is channelled back into Singapore’s electrical grid.

Meanwhile, HDB also called the fifth solar leasing tender beneath its SolarNova programme.

To insure 1,154 HDB blocks and 46 government websites, the latest tender will”reap 60 MWp of solar power islandwide, creating more clean energy and helping to decrease carbon emissions”.

HDB revealed that the six agencies will take part in the SolarNova tender, together with the Ministry of Culture, Community and Youth (MCCY) and Land Transport Authority (LTA) participating for the first time.

The solar leasing tender closes 2 March 2020, and can be defined as awarded in the next quarter of 2020. Installation of these PV systems is slated for completion by the first quarter of 2023.
