It may be true that electricity is not the basic necessity of life but its deprivation can cause us difficulties in accessing the basic necessities of life. Where there are no power lines life becomes quite difficult to spend, but now thanks to the sun we can now take benefit of solar energy.

Solar pumps are a clean and very simple alternative to fuel-burning generators and of course windmills. Solar pump has the ability to produce more water as compared to a windmill or generator even in the harsh climate. Solar pumps are basically designed in such a way that they utilize DC power supply from the panels consisting of photovoltaic cells. Solar pumps can also be modified to operate on AC power supply.

Solar Pumps

Solar Pumps

Solar water pumps are designed in such a way that they only use DC electric supply from a panel consisting of photovoltaic cells. They must operate at low power during the low light conditions. They must not be stalled or over heated.

Low pumps utilize low volumetric mechanisms due to which the water is sealed in the cavities and forced upward. Where there is a need for high volumes of water then centrifugal pumps are used.

Surface pumps are mounted on the ground level, whereas submersible pumps are lowered into water. Submersible pumps are quite common in deep water wells.

Pump Controller

Pump controller is also known as the current booster. It is an electronic device utilized by most of the solar pumps. It works like an automatic transmission device.

It helps the pump to start and preventing it stalling in case of weak sunlight.

Solar Tracker

Solar pumps are also fitted with solar trackers. Solar trackers adjust the PV array according to the position of the sun, thereby increasing the energy gain up to 55%.Where there is availability of more peak sun hours then overall cost can be reduced by employing a smaller pump and a smaller power supply.

Tracking is efficient most when the weather is clear and sunny, at the same time it is less effective as the weather turns cloudy and cold.

Storage

The most important part is that of storage. Storage depends upon the climate and the usage of water. It may be possible that only three to four days storage may be required. For the sake of simplicity and economy some systems use water storage rather than batteries. A float switch is fitted in the pump which turns the pump off when the water tank is filled, so as to prevent the overflow and wasting of water.

Advantages Of Solar Pumps

Comparison of a solar pump and a windmill is quite meaning less as the solar pumps are quite easy to install and maintain as compared to the windmill and also they are less expensive.

Livestock Watering

Solar pumps are used for watering the livestock. Cattle ranchers enthusiastically use solar pumps. Read the full story

We Share This Earth – A Provoking Thought

Climate change over the past decade has been one of the most serious issues for people. Global Warming has ignited several causes to save planet Earth. Earth is the home to several species of Plants, Animals, Insects, Birds, Marine life and Human Beings.

Why I Cant Be A Skeptic

Why I Cant Be A Skeptic

We come across the 4 seasons and experience the delights of Mother Nature such as rainfall and snowfall. We live here and it is our responsibility to work towards the betterment of this society. Scientists over a course of decades have come to the conclusion that if we do not take preventative measures to bring a change, the consequences may be dire. Here are the top 10 reasons why climate change cannot be denied by anybody.

Rise to 6 Degree Celsius – Proven Theory

The temperature of Earth may rise to over 1, 2, 3 or 4 degree centigrade over the next 50 years. What will happen if this occurs? Scientists have agreed mutually that if the Earth’s temperature rises by over 1 degree, the melting of Glaciers will continue. Many of the animals like Seal’s, Panda’s and Polar Bears may face extinction. The risk of flooding will greatly increase in the eastern horizons. Agricultural problems will surface. Many species of animals and birds will lose their habitats as well.

We Already See the Signs

Wars will be fought over the right to food and drinking water. Forest fires will become common and many of the worlds most scenic and dense vegetations like Amazon forest will become a victim of deforestation. People will resort to violence and the Earth as we know today may not ever be able to return to its normal climate.

4 Degree Rise is Proved

At 3.5 degrees rise, Earth will experience rash and unpredictable weather conditions. Tornadoes, Sea Storms, Hurricanes and flooding will be common. The snow accumulated over the European Alps, Indies, Asian Mountain Ranges and the North and South Pole will completely be melted. Antarctica will no longer exist. The world will fall in panic. 4 degree centigrade rise is much the same as 3.5 or 3 degrees. Low lying African countries like Egypt will be lost completely to the sea with Bangladesh. New deserts will appear all over the world in places like Spain.

Skeptic May Lose Life

These are some of the effects of a 4 degree temperature rise. Imagine what will happen if it crosses the checkpoint of 5 and 6 degrees? A major chunk of Earth will be uninhabitable for Earthlings. People will resort to Northern Europe as refugee’s. The resources to accommodate these people will slowly vanquish. Methane Gas will rise from the Ocean bed and add to the Greenhouse gases.

Things Need To Be Worked Out

Things Need To Be Worked Out

Weather change is one of the most deadly of issues these days. The reason why I do not doubt the authenticity of this cause is because I experience the effects of climate change myself. As an individual, one cannot neglect the effects of climate change. Read the full story

The use of solar panels is on the rise. Many people who want to save money are using solar panels to fulfill their energy needs. You can get the benefits of a residential power system. There are a few things which must be taken into consideration before setting up a residential solar power.

 

Position matters the most

The solar panels work on sunlight. They absorb sunlight and turn it into electricity or other forms of energy. Before installing your solar panels make sure that they are placed in position where they receive sufficient sunlight.

If your house is in an area which remains clouded or there are tall buildings, around it; which block sun most of the time, your solar panels may not work efficiently. If the solar panels don’t receive the required sunlight their performance will decrease.

For an optimized performance of the solar panel the tilt of the collector matters a lot. The panels should be tilted in the direction of the sunlight. If the panels are tilted low they will receive maximum sunlight during summer. Usually the tilt is same as that of the roof.

If you want the solar panels to collect maximum sunlight, position them in south. If they are positioned south they will receive sunlight for a long time. North is the least likely direction for your solar panels.

Understanding Climate and Weather

Tags: , , , , , , , ,


We all remember learning terms such as “climate” and “weather” back in our primary school days, but not all of us stay in touch with these (until commonly used) to be able to differentiate them. Let us take a look at what the weather of the earth is and what the climate is.

Climate of the Earth

climate of the Earth

The climate of the earth can be defined in different ways. It all depends on the speculations of the people. However, climate can be defined as the weather averaged for a long period of time. We can judge the climate, considering a number of years, by the rainfall and the changes in it’s amount, the pressure of the wind and the fluctuation of the temperature. Every place has a different climate. It depends on the location of the place, the sea level and the height from the sea level. Read the full story
