Solar Heating for hot water in your home
It lights our day and its been there for millions of years the sun, so has solar thermal energy, but to harness it is another matter, with the cost of energy going up and the lack of money, many people are looking for ways to save money, allot of people now use solar energy every day in their homes and even at the office.
Solar thermal energy can be used to heat water for showing, bath tubs etc, it can heat whole swimming pools, and you can even use it to heat areas or rooms, there is even some companies using the suns energy to boil water
with parabolic mirrors thus allowing them to run steam turbines to generate electricity for the grid.
Most solar heating systems contain glass and copper pipping, this is one of the best types to heat water, inside the pipework is lightweight aluminum absorber sheets, this helps for the best heat transfer, the system also contains a circulating pump, this pumps the water around the system until its hot enough to be stored into the water storage tank, the tank is much the same as a Electric hot water tank it even has the heating element for times when their is less sun or on cloudy days, the cylinder contains a thermostat when it cools down the water recirculates around the solar heating system, heating it up again.
The great thing about solar heating systems is that you can get hot water without burning coal, the energy is renewable and this will help reduce your energy bills quiet a bit, the solar system works best mainly in the summer time which you can get up to 90% of hot water, although during the cooler winter months, it should give you about 20% of hot water, you will save allot of money on your energy bills.
The cost to install such systems does cost much more than the average Electric hot water system, but the savings you will reap far out way the bills, besides many countries offer government rebates and the price of energy just keeps rising, in Australia prices of Electricity might rise as much as 44% by 2012, not only that but you will be reducing the carbon footprint.
We cant all get solar hot water sometimes due to conservation or maybe your renting a place, to install such a system would be out of your own pocket and many landlords like to keep their costs down as much as possible, but we can all play our part in saving energy lowering our energy bills, take shorter showers, wash clothes in cold water, hang clothes out to dry, don’t use a clothes dryer unless you really need to, and switch of appliance’s at the wall when not in use, we can all do our bit, remember if everybody does their little part, our environment will be a lot better for future generations.
Solar air conditioning for your home
Use the sun to cool your home or office will provide great cooling, savings and is environmentally friendly, this systems does not use the grid.
As we know air conditioning is something that we need when it starts to get hot, as the intense sun and radiation cause the building to heat up, a lot of people love the new type of solar cooling system, technology already was here back in 1878 it was first demonstrated, its basic components putting them together in an smart way, but turning the sun into cool air is complex process.
How The solar air cooler work it harnesses the sun and radiation then heats up solar panels simpler to hot water panels the heat which is gained through this process is stored in a large insulated tank, the heat is then used to drive an absorption chiller or a dehumidifier depending in your located in hot dry area or humid area.
The small amount of suns energy in winter can even heat your home in winter time thus saving you even more money and using less energy, and making hot water for you all year round.
In the end dry and the sun is used to process the cooling meaning using no electricity as compared to conventional air conditioning systems, low energy consumption mean less greenhouse gas and the gas that is used in the solar cooling system is greenhouse neutral, conventional air conditioning systems use a lot of energy and contribute to global warming, if a conventional air conditioner 3000 watts is run for 8 hours per day for 3 months of the year, over 700kg of CO2 is generated, as it gets hotter and global warming in cresses these conventional air conditioning systems will be less efficient meaning they will be used even more and put more burden onto the planet
People buying air conditioning systems are putting the price up on electricity because its not the cost of the unit but the more systems that are brought means more power needs to be generated causing thousands of dollars for infrastructure investment, this price is passed onto every consumer of electricity there for the need of solar cooling is paramount with heat rising and less use of conventional air conditioning systems, it will also save you hundreds of dollars every year that can go towards things you love.
There are already many hundreds of successfully installations throughout the world, but why hasn’t many people brought a new solar cooler, its because not many people know about these great systems and there is not much demand for them as of yet, plus service people tradesmen need the experience to installed these new systems, the systems are rather complex and need careful installation and design to perform at its best.
