Deep cycle battery harnesses solar power in Indonesia


Deep cycle batteries are crucial for the successful commercialisation and widespread adoption of solar power, or other renewable energy sources like wind or hydroelectric. It’s one thing to have a green power source generating energy, but the key is having somewhere to store and fluidly distribute that energy. Deep cycle batteries are an extremely cost effective way to do this and will last many years if the batteries’ efficiency is well maintained.

Innovations in the power and capabilities of industrial batteries are making solar an increasingly cost effective and therefore viable alternative to grid power sources. In addition, as traditional power sources are generated with fossil fuel, the benefits to using deep cycle batteries is not just financial, but environmental. The combination of solar power and industrial batteries is especially relevant for developing countries like Indonesia, where the rising costs and environmental impacts involved in fossil fuel use are substantial.


Indonesia’s economy and energy demands are growing, and the need for more power is resulting in rainforest habitat destruction caused in part by the expansion of coal mining. Hence the generation of solar power – and the use of deep cycle batteries to store that power – can help Indonesia meet the environmental and financial challenges posed by the growth of the archipelago.

Thankfully, because of its climate, Indonesia has immense potential to support the widespread adoption of solar power. Located between four degrees north latitude and eight degrees south latitude straddling the equator, Indonesia often gets more than five-kilowatt hours of harvestable power per square meter of land per day. Another favourable factor is the low average power usage per household in Indonesia, when you consider this; the numbers begin to make sense. To give you an idea of the scale of power usage involved here, the average Western home uses 16 kwh a day, while the average home in Indonesia only uses 2 kwh’s. This means that just a few solar panels per residence would be enough to reduce Indonesia’s dependence on the increasingly unreliable traditional energy grid.


Indonesia is well aware of this opportunity and has in fact made a pledge to pursue a goal of generating five million kilowatts (5GWs) by 2019, which would provide energy for 10 million homes. Larger applications, like commercial, medical, and industrial enterprises could also be powered by solar if enough high functioning deep cycle batteries are installed. Much of the ASEAN goal will be fulfilled by major solar generation parks built throughout Indonesia over the next decade. In fact, 2015 marked the start of construction for 109 of those sites across Indonesia.

To assist with the ASEAN goal, SEC is absolutely focused on channeling enormous amounts of resource into the Indonesian territory. We are excited about the opportunities the territory offers, as well as the challenges it presents us, and we are gearing up many initiatives across the archipelago. As part of our commitment we’ve begun converting our website into Indonesian and started opening offices across the territory.


Beyond the obvious environmental drivers there are also widespread financial benefits to using deep cycle batteries. Consumers with grid-tied solar systems already in place can set up a net metering agreement. In Indonesia, customers can sell the excess power from their deep cycle batteries straight back to the grid in exchange for credits on their electricity bill.

And, by storing freshly generated power with deep cycle batteries, utility companies can use solar systems to avoid having to build new coal “peaker plants” to meet shortfalls during peak demand. Instead, they can generate and store power during periods when the demand for energy is less than the production capacity.

As Indonesia’s economy and electrical demand grows, deployment of deep cycle batteries can vastly reduce the need to build new power plants, reduce the instability of the overloaded grid network and provide more energy security for Indonesian residents and businesses alike.


Deep cycle batteries are crucial not just for residential overnight storage needs, but for medium size factories and industrial scale solar power production facilities. Regardless of whether it’s a small island in the outer archipelago, a crucial hospital in the city, a factory, or even a power plant generating solar energy, the power is not always going to be needed at the moment is produced.

This means reliable cost-effective deep cycle batteries for storage will be essential to the successful implementation of solar as part of the Indonesian energy mix. Here at SEC, we are excited to meet the challenges of living in such technologically advanced times and we are making plans to help meet Indonesia’s solar storage needs with a new generation of innovative deep cycle batteries.
