Notable solar power and energy advances


Advances in the capabilities of energy storage have made solar power an appealing alternative to increasingly expensive fossil fuels. Take a look at this video of a recent renewable energy advance made by SEC and Solar Power Indonesia, then read on to discover our vote for five of the top new developments in solar power.

Our list features everything from Tesla’s Powerwall with its deep cycle battery, to a plane that flies using the power of the sun. You’ll see we’ve taken special interest in Indonesia, a beautiful archipelago where SEC has recently begun expanding operations.  In fact, we’re currently focused on channeling enormous amounts of resource into the Indonesian territory and are gearing up some quite remarkable initiatives across the archipelago.


As the video shows, selling power back to the local utility provider is an additional cost saving to storing solar power in deep cycle batteries. But until recently, grid-tied net-metering domestic solar power generation was not available in Indonesia. SEC, in partnership with one of our platinum distributors, has recently entered into Indonesia’s first net metering domestic grid tie agreement with the PLN utility company.

Find out further details about the agreement here and don’t wait to get in touch if you are interested in commissioning a similar project.

The first customer we signed up is located in Nusa Dua, Bali. They can now send the surplus energy from their deep cycle batteries back to the grid in exchange for a credit on their electric bill. And, as of March 2016, more and more Indonesian power users were free to sign up for the program, which makes solar power more cost-effective and contributes to grid stability.


SEC has long championed the use of solar farms. They’re generally large groups of solar panels based in fields or on rooftops to generate energy for surrounding areas. But in Japan, the electronics manufacturer Kyocera, is teaming up with Century Tokyo Leasing to build the world’s largest floating solar panel system on the reservoir of Yamakura Damn near Tokyo. The system has 51,000 panels and will generate around 14 megawatts of energy – that’s enough to power 5,000 homes.


Bertrand Piccard and Andre Borschberg are in the process of flying around the world in their aeroplane, the Solar Impulse II. Their mission is to support and promote clean technologies and as such, their plane relies entirely on solar power stored in the deep cycle batteries onboard.

Prior to this, solar aeroplanes have circled the globe many times, but they were ultra light crafts with no pilot. This plane weighs 2,300 kilograms and uses deep cycle batteries as a power source significant enough to carry a passenger. It has not yet completed its round the world mission – at the time of publishing the plane was in Phoenix but we wish them luck on their continued journey.


If you’ve spent any time at all reading about renewable energy you’ll have heard of the Tesla Powerwall. So despite the fact that it’s not ‘brand new’ in the market, we decided that the Powerwall, with its Lithium-Ion deep cycle battery, is well worth a mention.

When it comes to deep cycle battery chemistries, Lithium is a popular choice for manufacturers, but it does have cost repercussions. In fact, the expert juries are still out on the total cost of ownership for a Powerwall. But with its introduction, Tesla are no doubt responsible for cracking open the residential renewables marketplace. They’ve brought the ‘energy storage conversation’ to kitchen tables around the world, and for that they deserve recognition.

Having started only three years ago, Cochin International Airport in India has since expanded their solar project to 48,000 kilowatts. The 45 acre, 9.3 million dollar project provides all of the airport’s electricity needs, storing power in deep cycle batteries for overnight use – and even selling some power back to the grid.

Following this success, the Indian Minister of Civil Aviation has now directed all airports to incorporate solar power. Calcutta Airport plans to build a 70-acre panel array with deep cycle batteries to provide as much as 1/3 of their power.

With our recent expansion into the Indonesian territory, SEC can’t help but ask the question, could this airport solution work for Indonesia? The answer is mixed. Acreage is hard to come by near Bali’s popular Denpasar International Airport, but some of the twenty-three other international airports in Indonesia could find room for solar arrays.

And, with the possible options of deploying floating panels on the sea, even airports in congested areas like Denpasar and Jakarta could add solar power stored in deep cycle batteries to their energy mix. We look forward to being part of the developments in airport energy management.

SEC is a global company with subsidiaries around the world. While this article focuses on our projects in Indonesia, we’re poised to bring renewable energy options to businesses and communities all over the globe!
