Singapore Housing Board Awards Solar Leasing Tender of 130 MWp to Sunseap Leasing

Singapore’s Housing and Development Board (HDB) has awarded its eighth and largest solar leasing tender to date to Sunseap Leasing Pte Ltd, an entity of EDP Renewables APAC.

This tender, under the SolarNova programme, covers the installation of solar panels at about 1,075 HDB blocks and 101 government sites with a solar capacity of 130 megawatt-peak (MWp).

The SolarNova programme, rolled out under the HDB Green Towns Programme, is part of HDB’s efforts to reduce energy consumption.

HDB’s Chief Sustainability Officer and Group Director of Building & Research Institute, Tan Sze Tiong said: “The Green Towns Programme helps to mitigate climate change while creating a cleaner and more comfortable living environment for our residents, such as through initiatives that reduce energy consumption in our towns.”

“Other green initiatives introduced under the programme aim to recycle rainwater, cool our towns, encourage green commute, and reduce waste. We will continue to explore new initiatives to improve residents’ quality of life, stretch HDB’s sustainability targets, and support the national goal of achieving a green and sustainable Singapore.”

For the first time since the launch of the SolarNova programme in 2014, this latest SolarNova tender will include the use of a novel advanced technology to prolong the lifespan of solar panels.

Generally, solar panels can last about 25 to 30 years while undergoing natural degradation due to ageing and changing weather conditions. Due to degradation, a solar panel would on average, generate around 12% to 15% less power towards the end of its lifespan.

To prolong the lifespan of a solar panel, EDP Renewables APAC has collaborated with EtaVolt to pilot an advanced regeneration technology for solar panels on HDB blocks, which can extend the lifespan of each solar panel by 4 to 5 years.

This patented technology developed by EtaVolt relies on intense light to re-energise the solar cells and repair them at the molecular level, to recover up to 5% of the solar panel’s efficiency, depending on panel structures, in minutes. This advanced regeneration activity only needs to be carried out at most once a year.

Installation of solar panels under SolarNova 8 is expected to commence in 2Q 2024 and complete by 3Q 2026. HDB aims to install solar panels on as many blocks as possible.

To date, about 3,900 HDB blocks have been installed with solar panels. Solar panels for the remaining HDB blocks, where feasible, will progressively be installed in batches over the next three years. Actual installation will be determined based on the site conditions of each block.
