In Cambodia, electricity users can spend 15% to 35% of their electricity bill just on lighting. With Cambodian electricity prices among the highest in the world, lighting is one area where efficient solutions are possible and very important. Fluorescent technology offers 5% to 10% savings over incandescent lighting but there are many forms of inefficient incandescent lighting, halogen, high pressure sodium, and metal halide still in use. We launch new product LVD (Low Voltage Discharge) Induction lighting is also becoming very popular.

Fluorescent technology offers 5% to 10% savings over incandescent lighting but there are many forms of inefficient incandescent lighting, halogen, high pressure sodium, and metal halide still in use. LED (Light Emitting Diode) is very popular lighting and it is even more efficient than CFL but the real saving comes because LED lights usually last 5 to 8 times longer than CFL.

ESS has been installed solar pumping system at Kampong Thom Prison. This system can allows the pump to be powered by an AC generator or commercial utility power. The solar array remains connected. If the sun comes out again, less power is drawn from the AC source. A common application is for a portable genset (gasoline generator) to run a well pump. When the generator is stopped (or runs out of fuel) the pump automatically returns to solar power when the sunshine is sufficient. No manual switching is required.

In larger systems (which do not operate under the principle of thermo siphon) where the tank and the collector are separate heat pipes are used to enhance the performance of the system. This heat pipe is inserted into the vacuum/evacuated tube. This heat pipe is made of pure copper (99.9 % purity). In this heat pipe a thermic fluid / distilled water is placed.

On absorbing the incident solar radiation, the vacuum tube gets heated up, which in turn heats up the heat pipe. The thermic fluid/distilled water on being heated up forms steam and rises up. This steam then passes on the latent heat of steam to the medium (in our case water) which is required to be heated . By passing off its latent heat the steam condenses and forms a liquid. This liquid then comes down to the bottom of the pipe and the process is repeated.
