From the various literature and research this much can be saved:
1. LED lamps - 70 to 80%
2. Solar panels - 25 to 30%
3. Solar aircon - 40%
4. Aircon with inverters - 30%
5. Solar panels with inverters, battery 48 VDC - 70% this is surefire way to save most on the aircon but is the most expensive. A 1 hp unit could cost as much as P100,000 ( this could be explained by the added cost of batteries and solar panels for l hp - 700 watts)
Solar panels - P60,000
Batteries 20,000 each Germany made
