How much can be saved from Renewable Energy system?

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
