Moreover, a Solar Submersible Pump needs very little maintenance. Smart Solar Box Review   Installing the equipment is also very easy and could be set up even by a person who has very little technical know-how or expertise. They are generally installed on special ground or pole mounting structures. One of the greatest advantages of using solar electricity is that it could be used directly or it could be conveniently stored in batteries for future use. The batteries used in most solar powered water systems are called deep-cycle batteries and could be recharged whenever necessary. They also provide a consistent supply of power over a longer duration of time. And what more...! Using solar power to pump water is highly cost-effective and reliable, with a submersible pump and solar cell panel available for less than Rs. 70,000.

No matter what season you are in it seems that one of the constants are rising utility bills. With winter behind us, I was just starting to think my electricity bill would go down, only to come home and find that the summer has hit with temperatures over 40 degrees C, meaning that the air con unit has been on all day! So, what can I do to lower my utility bills. I have already done all the easy things, so now is the time to investigate alternatives.

About twenty years ago I had a house with a solar hot water service, it worked well and very cost effective. Having been around for so long it is well proven technology, but when I looked at the possibility of getting one installed in my current house the cost was prohibitive. Another approach would be to use that same source of power by collecting it in solar panels mounted on the roof and then store it, but again the cost of the panels and the batteries for storage was also fairly expensive.

However, another approach is to use wind turbines, which are just modern windmills, and instead of pumping water are designed to generate electricity. This technology has also been around for a long time and utilised in huge wind farms to provide energy to the commercial electricity grid. This technology has only recently been downsized to provide domestic sized turbines.
