Solar Leasing takes off

Idea to lease solar panels on contract is catching on with HDB but cost, hot property market could be dampeners

by Woo Sian Boon
04:45 AM Nov 14, 2012
SINGAPORE – A new concept that seeks to remove the hassle of installing bulky solar panels and drive down the costs of installation and maintenance is catching on among companies, schools and Housing and Development Board (HDB) flats. Called “solar leasing”, any organisation can lease solar panels under a 20-year contract with the leasing company taking care of designing, financing, maintaining and operating the solar photovoltaic (PV) systems. The tenants will pay 20 per cent of upfront costs and a monthly flat rate that is not higher than the retail electricity tariff rate. 

But before proponents can declare it as a possible answer to Singapore’s constant bid to diversify its energy mix – the concept has already proven to be popular in other parts of the world, including southern California, in the United States – experts had some reservations about whether the concept would take off here, even as the cost of solar panels head south. 

They cited the “short-termism” that is prevalent among private property owners. The fact that most Singaporeans live in public flats also meant that the Government’s buy-in will be critical. Moreover, the cost savings might not be meaningful for private properties, given the economies of scale. 

Deputy CEO of the Solar Energy Research Institute of Singapore Armin Aberle pointed out: “With solar leasing, you need a roof space for the next 20 years. It’s a long term investment and, in Singapore, very few people own their own roof space and have such long-term thinking, because of the hot property market … they buy and sell very quickly.”

Dr Arberle however, pointed out that the concept may be the way to go for new HDB developments.

The first solar-leasing project was awarded in September last year: The HDB awarded a tender to Sunseap Enterprises, a solar system developer, to lease two mega-watt-peak solar PV systems for 45 HDB residential blocks in Punggol. The installations were completed last month, and the system will provide power for common area facilities such as corridor lights and lifts.

Sunseap Business Development Manager Brandon Lee said his company is planning to offer the solar leasing service to private residences “as early as next year”. 

“For private residential buildings, the system size is smaller, so the unit cost will also be higher,” he said. 

Sunseap’s gameplan is to use its profits from companies and other organisations to subsidise the costs for individual households, said Mr Lee. 

PV World is the other company here that provides solar leasing services. Its Managing Director Loh Lean Chooi said households living in private residences may save “only about S$20 or S$30 a month” by leasing solar panels.

So far, a handful of entities have signed up for the leasing services, including Raffles Institution (RI). The school signed a lease last month for Sunseap to install 625 panels on two of the school’s blocks. The panels will generate up to 175,000 kilowatt hours of energy annually to power lighting in classrooms, lecture theatres, air conditioning units and fans. Neither Sunseap or RI would reveal the commercial terms of the lease. 

According to Mr Lee, the upfront cost of a system similar to RI’s would cost S$700,000. On lease terms, organisations need to fork out only 20 per cent of that, he added. 

Sakae Holdings was one of the first companies to sign a lease. It is installing some 1,400 solar panels on the roof of its headquarters in Upper Paya Lebar. Its CEO Douglas Foo said solar leasing enabled the company to invest in solar energy, despite lacking the necessary expertise.

Keppel DHCS has also leased solar panels for its district cooling system plant at Changi Business Park. The cost savings are estimated to be about 10 per cent per annum, said a the company’s spokesperson.

While Mr Lee was optimistic that more companies will come on board once the concept becomes better known, Mr Loh felt that the Government could do more to encourage companies to take up the service. 

“The Government only provides subsidies to buildings if they are able to achieve the Building and Construction Authority’s Green Mark status … Also, in other places such as Europe and Australia, subsidies are provided for the 20-year lease period,” he said.

Singapore’s rapid urban renewal rate also means that building owners are afraid to commit to a 20-year lease – the minimum tenure that is needed for the solar system developers to make a profit – for the solar panels. “This is another major problem we face here,” said Mr Loh.

Priority of funds in research depends on human & environment & economic values, what we are talking is it's potential to improve lives

There are a set of new challenges that we are faced with at the moment around resource shortages on the one hand, and around damage to the global commons on the other, and there is no question in my mind that there is insufficient research going into these areas.

If we look at resource shortages, we’re looking at issues such as energy, water, minerals, and food. These are practical outcomes that are of direct consequence to the survivability of our civilisation going forward.

We have got a wonderful new set of challenges for science and technology, and in my view, we have to refocus a lot more public funds into developing exciting new innovations to take us through this.

My position is that research into areas such as astronomy and particle physics is very interesting and is important because often this type of work attracts bright young people into careers in science and technology.

So there is a very good argument for funding what is intellectually interesting and challenging but may not have practical outcomes from the research.

In other words, it’s a question of priority.

Theoretical physics colleagues of mine have been teaching about the Higgs boson for many, many decades and now we have an experimental confirmation and we have added a bit of detail to our knowledge of the Higgs boson as a result – if indeed it is the Higgs boson that is being looked at.

As far as I know, directly from the result of the research into particle physics at these very high energies there has been no useful outcome for society from that research directly.

Maybe indirectly – and everyone quotes the World Wide Web – but if we look at the actual discoveries of particle physics over that last 50 years, there are no direct outcomes.

There has been a lack of funding for finding answers to the practical problems we face because of two things – one is myopia. We tend to be very good at dealing with a problem that is sitting right on our desks at this point in time rather than worrying about the next 10-20 years.

But the second is perhaps more important – inertia. Human beings tend to have, for very good reason, inertia built into them from the education system.

Secondly, we have infrastructure inertia. For example, every motor vehicle driving on the roads today is simply a linear extrapolation of the model T Ford, that has become more and more complex without actually qualitatively changing that manufacturing process.

Mobile Data Offloading after LTE? TD-SCDMA with Extended WiFi

Mobile data offloading (MDO) is the use of complementary network technologies such as Wi-Fi and media optimization for offloading data that is originally directed for cellular networks. According to a study done by ABI Research in 2010, MDO is predicted to triple in the next five years as it helps telcos save money and relieve network traffic. 

Locally, there have been some concrete developments in MDO via Wi-Fi. The InfoComm Development Authority (IDA) of Singapore launched Wireless@SG in December 2006, which is a wireless broadband programme that is managed by three local wireless operators – iCell Network, M1 and SingTel. 

As part of the Next Generation National Infocomm Infrastructure initiative, Wireless@SG aims to extend broadband access beyond homes, schools and offices to public areas. Over the years, the Wireless@SG network has been constantly upgraded to meet the growing demands for greater surfing speeds. For example, the Wireless@SG Enhancement and Service Adoption programme was launched in June 2009 to improve the user experience in the following areas: 

  • Higher access speed (has been increased to 1Mbps since September 2009)
  • Making logins to the network easier 
  • Easier access to apps and services 
  • Wide range of services in payments, security, advertising and location-based apps 

Previously, users have to key in their login information and passwords if they want to access Wireless@SG. This doesn’t really translate to a seamless user experience. Hence, IDA launched Seamless and Secure Access (SSA) on 10 February 2010 to enable users to access Wireless@SG without the need to re-enter their passwords on each login. It works on a similar concept as how mobile phones automatically log on to the respective mobile networks when the devices are switched on. 

The new automatic log-in feature is supported by the three operators of Wireless@SG with their respective Wireless@SG Connect apps. In addition, these apps have a suite of personalized services and apps such as a hotspot finder, mobile messaging and directory search.

Just two months ago, IDA just issued a Call for Collaboration to invite interested operators and service providers to submit proposals for the proposed next phase of the Wireless@SG programme, which spans from 1st April 2013 to 31st March 2017. Several of its objectives include: 

  • Continued availability of free basic Wi-Fi services for the masses 
  • To enhance the registration and log-in process through the implementation of an interoperable SIM-based authentication mechanism by 1st April 2014 and the development of SSA enablers for non SIM-based authentication.

Wright and Gene also agreed that a growth area for Spirent Communications is assisting telcos to do testing on Wi-Fi offloading. Telcos want to offload the data traffic to Wi-Fi networks but hope to keep the customer base.

According to Wright, Wi-Fi offloading currently does not provide a satisfactory user experience. The trend now is telcos are trying to control the implementation of Wi-Fi offloading; managing the offloading in way that is completely seamless to consumers yet at the same offering the same level of quality and security. In his opinions, Wi-Fi offloading is still in its early stages, and it holds a lot of potential in the future.

Data throttling is a form of network management where a service provider intentionally slows down the Internet connections of consumers who use too much data on its network. 

Believe it or not – data throttling has become a common practice among telcos around the world. According to The New York Times, Verizon, AT&T and T-Mobile have made it public that they engage in data throttling to keep the mobile networks usable for everyone.

Wright shared that telcos in the U.S. actually monitor the type of data that consumers are using. If a consumer is found to be hogging the network, the telco actually throttles the speed back and give him or her very low data priority on the network.

How do telcos actually know that? Well, Gene said that telcos are building “smarter” networks known as app-aware or content aware networks, where they can look into the data and determine where the traffic comes from. This is how telcos identify the individuals that consume a lot of bandwidth and penalize them.

Wright and Gene asserted that such practices are not usually made public and telcos would not admit it. However, Wright felt that telcos are forced to do so due to the congestion of the mobile networks.

We reached out to the three telcos in Singapore on their takes on data throttling, and you will be very surprised by what we’ve found out. As you might know, IDA works with the various service providers to provide a reasonable level of service quality to consumers. The authority is aware that service providers may need to manage their networks some way or the other in order to optimize the quality of their services to subscribers in general. You can find out more about IDA’s stand on this here.

Upon further investigation on StarHub’s website, we unravelled more information on how it manages the traffic on its mobile network. Similar to what we learnt from Gene, StarHub deploys network traffic analysis to identify the types of apps and associated usage patterns.  

The telco has been working with its technology partners to lessen the heavy burden caused by peer-to-peer traffic and video streaming on its MaxMobile network through the implementation of traffic shaping. According to StarHub, traffic shaping is a network deployment technique to provide control over the volume of traffic being sent into the network, either by specifying a period of time or a maximum rate at which the traffic is sent. 

Traffic shaping is similar to traffic policing, but instead of dropping packets that exceed the bit rate limit, the packets are queued and metered out so as not to exceed the bit rate limit. In short, traffic shaping is achieved by delaying some packets but not dropping them.

While data throttling can come across as shocking to consumers who do not know about it previously, it does seems like a necessary evil. Telcos have stated that a minority of their customers, usually 10%, are hogging the bulk of the bandwidth. Moreover, telcos have cited tremendous growth in mobile data usage over the past few years as reasons why they are changing strategies so that consumers can enjoy a more consistent mobile surfing experience. 

Telcos’ Network Enhancement Plans

While the deployment of 4G LTE networks is a great step forward for telcos to deliver faster mobile surfing speeds, telcos also understand the need to continue investing and upgrading their networks.

To further manage wireless spectrum efficiently, StarHub – togther with Microsoft Singapore, the Institute for InfoComm Research (I2R) and other members – are working to test TV White Spaces technology, an intelligent and efficient way in managing unused TV broadcast frequency bands which is critical for the development of next-generation wireless broadband services and smart-city applications.
