SOLAR ENERGY: Lee explaining how a lithium-polymer battery system can power up a small household
MALAYSIAN company ETI Tech Corporation Bhd claims to be the first in the world to introduce a lithium-polymer based battery system for solar-powered homes.
“The lithium ion battery is 100 per cent environment-friendly, unlike the more commonly used lead acid battery,” said ETI Tech Corporation Bhd managing director K. K. Lee.
“Also, lead has been banned in Europe as it is poisonous to the environment. What we have here is a battery that is not only green, but also has a higher charging and discharge efficiency and low running cost.
“Less battery packs are also required compared to lead acid batteries.”
Speaking to Malay Mail yesterday at their head office in Kulim, Kedah, Lee and his team had set up a small mock household to demonstrate how their battery system can work better than those that use lead acid batteries.
The mock household consisted of a TV set, a DVD player, three fluorescent lights and a fridge.
Executive director, Y. K. Khor, said that for the same length of battery charge time, the lithium-polymer battery can take in more power with only six pieces of solar photovoltaic (PV) panels. Lead acid batteries would require 12 panels for optimum load capacity.
Three lithium polymer battery units were used yesterday, with each of the units weighing 18kg — around 7kg lighter than lead acid batteries with similar capacity which weigh about 25kg per unit.
Khor said this breakthrough system is perfect for families staying in rural areas — which grid companies such as Tenaga Nasional Bhd have difficulty reaching due to financial and manpower constraints.
ETI Tech is a home-grown green technology company pioneering the use of green energy storage products. They are targeting community level electrification development.
The company also aims to eliminate harmful lead-acid battery use while supplying demand for renewable energy.
