Possibilities of Solar Power
in Cambodia
Day time in Cambodia is longer than night time.
Royal University of Phnom Penh
Institute of foreign languages
2014 - 2015

- 1876, William Grulls Adams

- 1950s, Calvin Fuller, Gerald Pearson & Daryl Chapin.

- 1960s, Standard for powering space bound satellites.

- 1970s-1990s, Exxon found the way to reduce cost of solar cells, began to use on railroad crossing, remote places to power homes, microwaves towers.

- Nowadays, it’s widely used.
History
Cambodia is a perfect place for Solar Power for 3 reasons
Cambodia has two regular seasons which are dry seasons and rain season. During the dry season, the sun shine is really perfect for the process of generating solar energy. However, during the rainy season the condition of generating solar energy is still excellent.
Reliable weather
Cambodia has a lot of places which are available for all kinds of solar power investment projects. : Cambodia has a lot of places which are available for all kinds of solar power investment projects.

Q & A
Initial cost
The cost of purchasing and installing of solar panels is high. However, the prices are falling rapidly.
The location and placement of solar panels is also major importance.
Pollution
The process of generating solar energy does not pollute the environment, but the process of producing photovoltaic does.
unrealiable
The photovoltaic panels cannot generate the solar energy during night. In some countries the weather is not reliable such as UK, some part of USA which make solar power inefficiency.
placement & location

Mega solar power plant in Japan
All in all, we can see that using solar panels have many benefits to the environment. However, it is still a hard choice for some countries because of the high price, placement and location, pollution and unreliable. Nevertheless, solar energy is very suitable for Cambodia.
Advantages
Free & cost effective
Sunlight is free. There is only cost of equipment.
Non-polluting
Solar energy is an excellent alternative for fossil fuels like coal and petroleum.
Accessibility in remote location
Solar power can generate electricity no matter how remote the area as long as the sun shines there.
maintenance free
Once a photovoltaic array is setup it can last for decades.
Photovoltaic technology is still expensive but the technology is improving and production is increasing.
The danger of further damage to the environment is minimized.
It can be added with ease and almost with no major revamp.
