Solar Lighting: Benefits for the Rural Areas of the World

ruralareasdevelopingcountriesIs solar lighting a fad, something that a really great marketer made up to get people to believe they’re actually helping the environment? Or are there real and substantial benefits to switching to solar lighting.  The places where we would see the biggest advantage are in rural areas of developing countries.  The developing world has significantly benefited from the use of solar lighting in rural regions. Here’s why:


Solar lamps replace kerosene lamps, which are a serious fire hazard in the developing world. There are tens of thousands of people killed every year from fires caused by kerosene lamps. Solar electric is a safe way to have lighting without the risk of fire.

Lighting After Dark

Having cheap, solar powered lighting after dark allows families to work longer and get more done. It has been shown that regions where there is more solar lighting have increased economic activity because they can work longer. Bringing in solar lighting into a rural area also brings more economic activity with the sale of lighting in that area.

The other side of this is that literacy rates are also increasing as people can now read after dark more easily than they can by candlelight. People in rural areas can now seek education more readily and also attach themselves to the modern world.

Saves Energy and Reduces Air Pollution

Solar lighting allows rural areas to save electricity costs, which can be put towards the lighting of their centers, or more urban areas. The use of solar power also decreases the air pollution in a region, which can also keep the agriculture healthier.

Improves Health Programs

The use of solar lighting system by health centers in rural areas also improves the quality of the care. Solar systems will allow power to be on longer and will improve the actual ability to see properly, ultimately leading to better diagnosis and treatments. Even childbirth often happens in the dark.

NASA Warns Interference on Earth by Solar Storm


WASHINGTON – The National Aeronautics and Space Administration (NASA) said that communications on Earth could be affected after the Terrestrial Relations Observatory (STEREO) and the Solar Observatory and Heliosfértico (SOHO) detected two flares enromes.

The first was billed as the largest of the solar activity cycle and the second largest recorded since 2006 moving at a speed of over 2 000 kilometers per second, while the other, a little slower, travels to about 1.770 km per second.

Because of this phenomenon, NASA expects the electromagnetic storm caused by solar activity on Earth and Mars close to 18:25 GMT.

It is also hoped that in its route passes by several NASA spacecraft such as Messenger (studying Mercury), the Spitzer telescope and STEREO-B and although the agency did not show concern for their ships, said he could register network problems Power supply high frequency radio and GPS as a result of radiation levels.

Experts estimate that the effect could extend up to three days, although the greatest impact will occur in the first 24 hours.

NASA said that the Sun goes through regular cycles of activity and every eleven years or so, there is a peak in their activity, causing storms that sometimes deform the Earth’s magnetic field and may even cross it and this is one of those years .

The flames originated in the region AR 1429 which has increased its activity in recent days and is the area that also produced two solar mass ejections traveling at 482 kilometers per second and could reach Earth within the next days.

Plasma from these ejections can create a severe geomagnetic storm that could also affect communications and cause auroras could be seen at low latitudes to central Asia.

New generation of solar lighting

For those of you who don’t know, the principle of operation of a solar lighting is that a photovoltaic panel “captures” the solar energy, it converts it into electricity and sends it in batteries or batteries, where it is stored. The lighting device (usually a diode for low power consumption) is then fed by the battery / batteries.
