Passive Solar Cooling makes use of the design of a building to naturally heat and chilled your home using passive solar energy.
Solar Desiccant Air Conditioning is an ingenious new way of cooling the air by using a material such as salt that will dry out the air, thus lowering the temperature. As the salt absorbs moisture, it becomes more liquid, so solar energy is used to heat the salt and return it to a dry state to continue its work of cooling the air. It is a renewable way of cooling the air without the higher energy consumption used by traditional air conditioners.
Solar Thermal Solar Cooling is often used in larger buildings, and makes use of solar energy to collect heat from the sun which then operates chillers which chilled the air. Read more...
How Solar Power Birdbaths Work
The units can be created with one or more tiers. The top tier will house the fountain and the solar cell, in most cases. Some solar bird bath styles include an extension wire and an outside solar cell that can be driven in to the ground on a stake.
These cells permit the bird bath to be placed in the shade while the solar cell continues to collect the direct sunlight for power.
Prices for these environmentally friendly outdoor solar fountains start at about $125. Depending on the size of the bath, number of tiers and materials from which the bath is made, the price can rise to much higher amounts.
Most of the cost pays for the solar cell and conversion unit used to capture and convert the sun's energy.
There are no moving parts on most units, but that does not mean maintenance is not required. As is the case with any standing water unit, debris can collect in the water and obscure the sun from reaching the solar cell. Algae can also cause a reduction in energy production. Water should be treated with anti-algae agents and changed frequently. Read more...
Discover What is Solar Oven?
For example, a woman in a developing country who needs to cook several meals using a traditional stove will need wood cut from local trees in order to fuel her stove.
Imagine the freedom when she suddenly has the capacity to cook meals without spending time cutting down trees and building fires, or adding smoke pollution to the air!

What is a Solar Water Heater
A solar energy water heater makes use of what are called solar collector panels. These panels are set in to the roof of your house. In the event you have a typical one relatives home then you would have a couple of solar collector panels on the roof. The panels are like skylights and are ordinarily around three feet wide and from seven to ten feet long. You would also need to have a solar water tank installed for the panels to do their job. Your water supply is then connected to the solar water tank.
A solar heater works via the solar panels and a solar water storage tank. There are two basic types of solar water heaters and they are known as active and passive solar water heating systems.
The active system uses circulating pumps and controls like a traditional water heating system, while a passive system does not have these things. Although passive systems are not as expensive as active systems, and are more reliable and often last longer, they are not as efficient.
One of the most important things you should have if you want your solar water heating system to function properly is a well insulated storage tank.
Solar water tanks also have an extra outlet source and inlet source. You can get two-tank solar water heating systems or one-tank solar systems. Before the water goes into the ordinary water it is first heated by the solar powered water heater in a two tank system. Both the back up heater and the solar water store are combined in a one tank system.
Whatever kind of solar water heating system you have installed, there are other things that you can do if you want to lower the cost of your water heating bills and run a ‘greener’ home – this is especially relevant to people with an active system that requires back-up. Some energy saving devices need to be put in place when your solar hot water heating system is installed. Read more...
Tips for Choosing the best Heating System for Your Home
The cost is one obvious factor. Calculate the cost of the process & the projected heat output of the process. For example, if the process cost is $10,000 but is projected to save $100/month in actual heating bills, are you willing to wait 8 years for the payback in energy savings?
Of work, if energy costs go up before that time, the savings will be greater & the payback of the process will be seen much sooner. Not only that, keep in mind that most systems obtainable for purchase have a 10 to 30 year warranty & can be expected to have a life of several decades.
Depending on where you live, the addition of a solar home heating process can yield a net increase in the worth of your property. In most cases, you can expect on selling your home to make 50-80% of the cost of the solar heating process back. Add that back to your energy savings in the house & you can expect a respectable return.
The type of solar home heating you need could depend on the climate you live in.
Will the process be passive, active, or a combination of the two? In the event you happen to live in southern Georgia where the climate is mild, a simple passive process (such as one that could be incorporated using a sun room) may serve to dramatically decrease your dependency on traditional methods of heating.
A new home is simpler to build a new solar heating process in to than an already established home. In order for solar home heating to be fully effective, the home needs to be properly insulated & sealed.
Also necessary are windows that have a high insulation value but permit solar radiation to enter basically. These windows are coated or glazed to permit sunlight in while trapping that energy once it’s in the house. Read more...

What is Passive Solar Energy ?
There are 3 different types of passive solar energy that can be used for your home:
direct gain
indirect gain
isolated gain
Direct Gain Passive Solar
Direct gain passive solar energy involves the use of south-facing windows, normally on a large room such as a relatives room or parlor. A kitchen or dining nook can often also provide a large amount of solar heating, depending on their place within the home.
Direct gain solar energy involves sunlight being allowed to come in to the home, normally through specially glazed windows, allowing dark masonry floors and walls to be warmed in the work of a winter day.
Those floors and walls store heat energy that in turn will be slowly released in the work of the nighttime hours. The glazing on the windows allows for the free movement of solar energy in to the living space, while decreasing the movement of heat energy out of the house.
Indirect Gain Passive Solar Heating
Indirect gain normally involves the use of a trombe wall or another kind of material that is placed between the sun & your home.
A trombe wall is made up of a south-facing masonry wall & a single or double layer glass placed about one inch in front of the wall.
This glass serves the same purpose as the windows in the direct gain model, allowing solar energy to warm the dark masonry wall while trapping heat energy between the glass & wall.
Throughout the day, the wall warms & heat energy begins to move through the masonry to the inside structure. The average masonry wall is 8 inches thick & allows the movement of heat at the rate of 1 inch/hour.
Isolated Gain Solar Energy
Isolated gain is a more complex kind of passive solar energy that heats air or water which is then circulated in a loop to provide heating or cooling for your home. The isolated gain solar system is kept separate from the other areas of the home and the sunlight is passed to those areas that most need it.
One of the most common types of isolated gain systems makes use of a sunroom which is attached to the side of the home, combined with an air collector which helps to move air through the home to a storage system in the house.
Isolated gain systems need to be exactly calibrated to keep the home at an even temperature Read more...
DIY solar energy system
Consider first:
Does the south side of your roof receive a maximum of four hours of direct sunlight each day? Solar cells must have sunlight in order to produce electricity.
Are you comfortable jogging on your roof? The pitch of your roof may choose for you whether or not it is possible for you to to, or require to, install do-it-yourself solar panels yourself.
In case you feel the pitch of the roof is risky, then the installation of your solar panels will require a professional.
Choose whether you’ll be living in your home long to recoup the investment you’ll make in your diy solar energy process.
Solar energy do-it-yourself systems can be obtained online or through a local retailer. Prior to making your purchase, check to see if the company offers technical support, a warranty on the product or its parts, and a resource list of contractors who are qualified to make warranty repairs. This is important information that hopefully you’ll never require, but it’s nice to have it on hand! Read more...
What Does a Solar Powered Process Do For My Home?
Solar panels or solar shingles installed on your roof capture the sun's energy and convert that energy in to DC power. The DC power is then sent through an inverter box, which transforms the energy in to AC power.
AC power is the type that you need to run your appliances, turn on lights, & heat your water. There's different types of systems you can think about. Keep reading!
A home that utilizes passive solar energy is designed and built to take full advantage of the sun's energy anytime the sun is shining. Passive solar is usually designed in to new construction, but sometimes can be added to an existing home.
Fundamentals of passive solar house designs include orienting the home to the sun, design of the home such as window placement, and ventilation that allows hot and chilled air to move through the house. The materials used to build a passive solar home (thermal mass).
An active solar home makes use of electrical fans or pumps to move the energy captured from the sun each day throughout the house. Read more...
Eleven Reasons to Pick Solar Energy for Homes
This is one of my favourite facts about solar energy. Did you know that our stunning Earth receives more energy from the sun in a single hour than the whole population can use in a year?!! Wow!!!!!!
Home solar energy systems have four parts. These parts are the solar panels, inverter, battery, charge controller, wiring and supportive structure.
The panels collect the energy. Inverters transform the energy in to a useable form. Batteries are there to collect additional energy that is not immediately used and the charge controller ensures one battery is seldom overcharged by moving energy to another battery when the first is full.
A one-kilowatt home solar process will generate about 1,600 kilowatts of power per year. The unit is made up of 10 solar panels and can take up to 100 square feet for installation.
The one-kilowatt home process can produce energy to prevent the burning of over 150 pounds of coal for fuel. CO2 release is reduced by 300 pounds and 105 gallons of water is saved - EVERY MONTH!
Each solar panel is comprised of about 40 individual solar cells. These cells are mounted on one board. The one-kilowatt home solar process will need about 10 of these boards, which is equivalent to 400 solar cells.
Battery backups can be used to supplement electric use on days when the sun is not shining. For example, the energy that is collected when no one is home can then is used to power the house in the coursework of a day of rain. The energy is not lost, stored and used later. The more batteries on the process, the more energy stored.
Additional energy may even be fed back in to the local electrical grid for credits. This means collecting credit money from the electrical company that can be used to supplement the solar process free when cloud cover or other climatic conditions that inhibit solar energy collection drain battery stores.
Solar panels do not must stand out on the roof in plain sight. The units come in a variety of colors that can be selected based on the color of the roof. Some homeowners are so proud of their systems that they select a brighter color so the unit will stand out! The color of the solar panel does not affect the performance.
In some cases, local and federal governments will provide tax credits to homeowners who install a solar process. The tax credits can greatly reduce the preliminary cost of the solar energy panels and reduce the time needed to see a return on investment.
Solar panels are often warranted for up to 25 years. The total life of the panels can extend as far as 50 years.
Solar lighting systems can collect sunlight and transfer that energy by fiber optic cable to light a complete home.
The true facts about solar energy are to make somebody require to run out and buy a solar panel process! Read more...
