In the DTI primer for energy requirements in the PHL, it was placed:
l. That PHL needs 4,000 mW of additional power in the future (next 5 years)
2. Investments in solar energy is only 1%
3. Sun power has invested PHP 27 billion in a solar manufacturing plant in the PHL
What are the opportunities

Solar air con
Philippines | April 22, 2013
One of the solar devices is the solar aircon. Some of these are being marketed in the internet and at malls. It is not however powered by solar panels.
The idea is to get a little help from the sun in running the air con refrigeration system.
The aircon cools the room by evaporating the refrigerant; the principle that liquid that turns into gas absorbs heat and that it releases heat as it becomes liquid. Now the evaporation process is done by a compressor using Boyles law, ie that by compressing, the temperature rises (to say l70 C). In a solar air con, the refrigerant passes through a coil heated the sun which superheats/preheats the refrigerant. This process reduces the power requirement of the compressor (as not much energy is needed) to vaporize the refrigerant. So there is an additional coil outside the aircon unit. Any aircon unit can be converted to solar.
Power savings is estimated to be 50%
Some are hybrid system that uses: both the passive system and solar panel

Solar supplier still focuses on solar gadgets, street lights - not the power gen
Rizal PHL | April 22, 2013
I met a solar supplier last week and he is a Chinese and he gave me contact number from China. He gave me a folder and presentation. His prices are stiff and his products revolve around gadgets: solar powered portable lamps (50 watts) solar chargers, led lamps, and his main focus is solar street lamps. His PTM are mostly LGU and he is the biggest supplier in Palawan (for street lamps?)
He gave me though a contact for solar irrigation. If he gives me an affordable price, then we can help many farmers. in rural areas who are burdened by fuel cost for irrigation and NIA water fees.

Bikershare is another alternative energy source
Angono, Rizal PHL | April 22, 2013
Another way of saving energy is to use bikes in the city commute in lieu of bus and automobiles. You use pedal power instead. No pollution, it is renewable and is cheap. This has been in use in China and in Europe. This is known as bikeshare in Europe and is in wide use in major city, like Amsterdam. You can go around the city by renting bikes in several points using prepaid cards or coins. You get a bike, and when you reach the destination, you park and lock the bike. Then when you move on, you pay for another bike and so on.
This movement/idea has found its way into New York City and Washington DC.
There is large growing number of workers but mostly construction workers who commute by bike. (This is dangerous still because many vehicle drivers intimidate the bikers)
I think they are starting this in Makati by having bike lanes. But unless the pollution levels in MM is uncontrolled, bikeshare will not prosper. We will just kill the bikers with respiratory diseases
