Solar Water Pumps

Since as long as anyone can remember, solar power has mainly been used to dry clothes and food. However, in the recent times, solar power is gradually becoming an important source of energy as more people are opting for this renewable source rather than fossil fuel, a non-renewable source of energy. So, what is solar power? This can be described as the use of the sun’s energy either directly as heat or indirectly by harnessing it using solar panels in order to generate electricity.

The main reasons as to why Solar Power is gradually phasing out fossil fuel are:

·         Solar power is inexpensive as one only incurs initial costs of setting up and it is free thereafter; also, it avoids the costs associated with environmental degradation.

·         Solar power, unlike fossil fuel, is clean energy and it, therefore, does not harm the environment in any way.

Solar power is used in a number of ways including water heating, lighting, cooking and water pumping among others.

Despite having all the above uses, solar powered water pumping is the primary focus of this article. Solar powered water pumping could be either around the house, for the fountain or even for irrigation. Use of solar energy to pump water is not only pocket-friendly but also a very reliable method to provide water, especially in areas where water points or resources are vastly spread; no alternative source of energy is available; or fuel costs are fairly high.

Solar water pumps are quite dependable as they can operate in almost any location and are at their utmost capacity when needed; during dry, hot and sunny periods. This, therefore, proves very helpful for the farming sector; in animal grazing and other farm activities like irrigation.

Solar water pumps also come in handy in remote areas that are far away from the national power grid. In such areas the connection fee to electricity is usually high and it is, therefore, cost effective to use solar power to pump water.

Some of the other merits of solar water pumps may include unattended operation, low maintenance, easy installation and a longer life span as compared to other pumps.

Despite seeming greatly advantageous, solar powered water pumps also have their demerits which include:

·         The high cost of procurement, which is the capital. Solar powered water pumps require a large amount of money to set up but it is much cheaper to maintain afterward. This, therefore, could pose a challenge for a larger population to get access.

·         Solar powered pumps may not be as dependable in rainy, cold or cloudy periods when there is completely no sunlight. Hence, this forces people to seek alternative means of pumping water during such periods.

·         Despite being cheap to maintain, repairs and service of solar powered pumps often require skilled personnel. This is a major challenge in the rural areas.

All in all, solar water pumps are a better alternative to the other types of pumps because the use of solar energy is free, environmentally friendly and increases human productivity. What more could you ask for?

Solar Home Lighting System

Recent developments have proved that solar lighting system has become the frontier in the lighting scene; gradually replacing the conventional, traditional hardwired lights. Thanks to a better understanding of solar energy, solar lighting has not only become an efficient but also a beneficial source of illumination. Unlike in the past where it had been to be restricted to outdoor places and specific occasions, solar lighting has now become versatile and is being used even in our homes. They could be used outside as security lights, in the shed, in the gardens and even inside the house.
So, why are people now embracing this form of lighting which has now become more than just a novelty object?

·         This source of illumination is pocket-friendly. The only cost incurred is the capital when purchasing the system and it costs nothing thereafter. So basically, there are no maintenance costs or monthly utility bills for lighting your home. This factor actually makes the solar home lighting system a requisite for every home.

·         Solar home lighting system has a lower energy consumption rate as compared to the hardwired lights. The solar powered lights can usually remain brightly lit for 8 to 10 hours. This can be owed to the fact that there have been immense improvements in the field of solar energy.
·         Another reason that this lighting system is gradually phasing out the hardwired lighting system is the ease of installation. Unlike in the past where it was characterized by bulky solar panels and unending lengths of wire, most solar lighting systems have become wireless hence making installation less complicated. This, therefore, means that one can make do without professionals for installation. All one has to do now is just put the panels in perfect place- where there is consistent bright sunlight- and that is all.

·         Solar home lighting systems are a savior in the case of power blackouts, especially at night. An amazing fact about solar lighting systems is that they have rechargeable batteries which store power that can be used later on even in the absence of sunlight. This stored power can be used for up to 8 hours which is basically one night. A perfect example of this is the solar spotlight.

·         Due to its versatility, a solar lighting system can be used almost anywhere within the home. One can easily move the lighting from one point to another if they notice there is not enough light in one place. This is unlike the traditional hardwired lighting system where one has to hire a professional to redo the wiring hence becoming costly and time-consuming.

However, there is a major mistaken belief regarding solar home lighting system; most people believe that the solar lighting is only usable during the summer season and is useless in the winter. In other words, this is trying to insinuate that the sun does not come out during winter, which is wrong. Solar lighting system function even on days that there is not enough sunshine as they are able to save energy in their internal batteries.

To sum it up, solar home lighting systems are a must-have for every home due to the numerous advantages it has. Let us not forget that the world is trying to go green; so why not embrace green energy?
