Solar Water Heating using Hi Temp Flat Plate Collectors

Posted by admin On September - 5 - 2010

Using Free Energy from the Sun to heat water is the best use of solar energy. Today, millions of homes and businesses around the globe use solar water heating systems because they are cost effective.

Solar Water Heating is the First Thing To Do when going solar! Solar water heaters are the most cost effective way to reduce carbon emissions and reduce dependence on imported energy.

Harnessing the sun’s energy to heat water makes sense, after all, it is one of the oldest uses of solar energy! Family’s water heaters consume more than 50 trillion kilowatt-hours of energy every year and creates millions of tons of pollution.

Did you know the Pure energy of the Sun produces enough power in less than one hour to meet our World’s Energy needs for a Year!

Shrink your Power Bill with the Pure Energy of the Sun! A powerful, attractive “Hi Temp” ZERO pollution water heater puts the sun’s energy to work in your home.  It will work hard for decades to shrink your high energy bills and cut environmental pollution for decades to come.

With Eskom’s proposed rapid price increase expected this year private households must prepare for higher electricity bills. Electricity that costs 60c/KWh now is expected to cost R 1,60 by 2012 . That means an electricity bill of now R 800.00 will be nearly R 2,160.00 in 3 years. Eskom has asked to increase the cost of electricity by 45% a year for three years after raising it 33% this year.

SA Leads the way with Solar Technology

Posted by admin On November - 17 - 2008

South Africa is at the forefront of the development of new solar power technology that will offer consumers a cheaper and highly efficient alternative to standard solar panels.

SA Good News The breakthrough technology is the result of over 13 years of research by the University of Johannesburg’s Professor Vivian Alberts. His solar panels are made from a unique metal alloy that converts light into energy at a fraction of the usual cost.
Unlike standard solar panels that contain a 350 micron thick silicon layer, Alberts’ panels make use of copper, indium, gallium, sulphur and selenium. The result is a revolutionary thin panel, approximately five microns thick (a human hair is 20 microns thick), that can be sold at a dramatically lower cost.
The elements used in Alberts’ panel are all semiconductors making his technology far more effective in attracting heat.
"The technology has proved itself in the pilot-plant phase, without a doubt," Alberts told Engineering News in 2005 when the breakthrough was first announced.
Following his discovery,  Alberts and the University of Johannesburg formed the company Photovoltaic Technology Intellectual Property in 2005 (PTIP). The company has since entered into agreements with a solar energy investor in Germany known as Johanna Solar Technology. Currently work is underway on the establishment of a purpose-built plant where the solar panels will be built.
According to Engineering News, PTIP will be building a local manufacturing facility with South African investors that will produce 450 000 panels a year.
The South African venture has earmarked a site in Paarl, in the Western Cape, for the local solar panel plant and the project is in the process of securing financing.

Using Solar for Household heating

Posted by admin On September - 27 - 2008

A solar heating system is used for heating purposes by using solar energy instead of conventional energy sources like fossil fuels (coal, oil, and gas) or electricity. In simple terms, a solar heating system focuses solar heat on a fluid (air or water) held in its collectors. According to the mechanism of driving the fluid through the system, there are two main types of solar heating systems: active systems and passive systems. Active solar heating systems use a pumping mechanism to drive the fluid through the collector while passive systems make use of natural convection in fluids to get them moving through the collectors. Active solar heating systems are more practical to install at home and are thus recommended for household heating purposes. In addition, they are more cost effective than passive systems.

Selecting a Solar Heating System

A number of factors need to be considered while selecting a solar heating system for home use. Some of these include the location of the house, its design, and the heating needs. In addition, the local climate and the type of system collectors determine the production of heat by the system. In general, the customer should select a system that can meet over 50% of the household heating needs. It is both not practical and not cost-effective to purchase a system that would meet all the heating needs. The best strategy is to keep a back-up heating system (fuel or electricity) for use in case the solar heating system fails to serve the purpose or goes out of order.

Cost of an Active Solar Heating System 

The cost of an active solar system for heating houses varies, depending on several factors. Usually, the present cost of an active solar heating system ranges from R300 to R900 for each square meter of the collector area. This is particularly helpful in cutting low the heating costs in winter. Above all, solar heating systems do not pollute the environment with noxious emissions like those produced by fossil fuels.

Installation and Maintenance

Ideally, a solar heating system should be designed and installed by an experienced contractor. The maintenance measures for the system depend on its type, usually averaging between 8 to 16 hours of maintenance each year. In the majority of case, the home insurance policy covers the maintenance costs of solar water heating systems.

DIY SOLAR- Build your own panel

Posted by admin On September - 21 - 2008

This is the coolest DIY project I have seen in a long time, and definitely an interesting project if you want to live off the grid. Fifteen columns of soda cans are used to harvest the suns rays and provide some pretty good water heating performance.

Solar Power Energy for Sustainable Living

Posted by admin On September - 10 - 2008

Solar power energy has been used for centuries to dray laundry, grow crops and sustain life.  Increasingly now it is being used to create energy and generate electricity.  Solar energy is one of the free gifts of nature.  Its biggest advantage is it is renewable, and it is great in areas which receive a lot of sunlight and have poor power generating infrastructure.  The disadvantage of this system is that it cannot collect energy in the night, and it requires a number of collectors to generate a little bit of solar power energy.

Benefits of Solar Energy

Solar power energy can be harnessed by using solar cells, also known as Photovoltaic cells, which convert sun’s rays directly into electricity.  The power generated from such sources is used in satellites and for electrical appliances used in homes.  Solar water heating can be done in many ways.  One common method is to heat up solar panels on the roof which in turn heats water for home use.  Solar heating is created by heating up cold air through solar collectors and circulating the hot air in the rooms.  The hot air is circulated when the hot air rises and the cool air enters the room and is heated through the solar collectors.  The air flow continues thus continuing to heat the air and circulate it.

For the average household, the main benefit of harnessing solar power energy is saving on electricity bills and creating an alternative system of power that can sustain during power outage. The other major benefit is the backup heaters that come handy to heat water during cloudy days.

With so many benefits, what is keeping solar power energy to be used in every household?  One of the disadvantages is the cost of a complete system. Presently, the system is not cost competitive on a standalone basis.   In residential areas where there is a grid tie up connection, solar power energy makes a lot of sense.  In off-grid areas, it is more advisable to use solar energy for street and garden lighting, highway call boxes, etc.

The increased usage of solar power energy will depend a lot on government policies and the incentives offered to encourage people to switch to solar energy.  A number of countries have established attractive incentives for the development of solar and other renewable energy sources.  Direct subsidies to end users to offset costs of solar equipment and installation charges being one of the main incentives.
