During the summers, the sun shines in its full glory over our heads and makes us sweat like pigs. This results in the extra consumption of electricity to power our air conditioners and our coolers. Electricity bills touch the ceilings during the summers because of 24 hours of usage. But now, this can be warded off by making use of solar coolers. Solar coolers are just like conventional water coolers. The only difference between the two is that, the former operates on the DC power produced by the solar panels and the latter one operates on AC power.
The best quality about the solar coolers is that they can be made out of any conventional water cooler and still costs only 1/4 to 1/3 of power consumption of conventional units. It is an able decision to make use of solar power to run the water coolers because it is due to the sun only that their need arose in the first place. Making the optimum use of solar power during the daytime to power up the solar coolers would surely help in saving of a lot of electricity thereby putting off the burden from the electricity bills. During the night time, the solar coolers can be run by the battery backup that stores the solar power during the daytime. This makes the solar coolers function 24/7 and serves as a feasible alternative for the humans.
Solar coolers are very easy to make from any conventional water cooler. To make a solar cooler, attach a 12 V automobile radiator fan and a bilge pump to the traditional cooler. The original fan and motor need not be removed for the purpose. The radiator fan can be mounted in front of the squirrel cage fan present in the water cooler. The bilge pump, too, can be placed next to the original pump inside the cooler. Conventional water coolers run on 110 V of AC power, whereas the solar cooler runs on a 12 V solar panel attached to it. The solar electric panel can be mounted on the home made tracker, which helps in extending the time period of solar coolerís working. It has been noticed that almost 2 to 3 hours of extra usage is possible with the tracker.
Solar coolers are very economical and to get the best out of them. One must switch it on since early morning when the sun comes out. Ideally, an AC or a cooler is turned on when it begins to get really hot. But with solar coolers, it wonít cost a penny to start them since early morning. Itíll be put to maximum utilization and will keep the house temperature at about 15 degrees.
Solar coolers work best in dry climate areas. They are eco-friendly and donít add to the unlimited pollution already surmounting the earth. Solar coolers help in preserving the priceless non-renewable sources of energy, which goes to waste in an unrestricted manner during the summers. Going solar with solar coolers is the coolest decision one can take for themselves as well as for the environment.
