Why Use Solar Energy?

Perhaps everything in the world is fine with your life. The last thing you care about are trees, fresh air and clean water. Heck, the water shows up every time you turn on a faucet, the heat comes on when it's cold, the light switch brings you light. What's there to worry about? Consider that this is just the problem. If you don’t care for the environment, the faucet may not bring you clean water, the heat may not go on and the car certainly will not start. If the environment is kept clean and left to do what it was intended to do, everything will continue to work fine. But get in its way and everything you thought was fine won’t be for long.



One way to accomplish the goal of keeping all the comforts of home working properly is by using other sources of power generation like the sun, not generating nasty things that get in the way of the environment doing its job. Current sources of power come from dead things like old forests gone millennium ago. Environmentally responsible power, heat and transport come from living or energized things like water and oxygen molecules. Sun can be turned into electricity and used to power your car, heat your home and generate your light. But to make the process work, you need to be able to see the sun, which means caring for the environment and not getting in its way.



Cost savings



One of the best things about caring for the suns ability to do its job is that it saves you money in the long run. Once solar systems are purchased and installed, they cost little if anything to operate. In most instances, the government will even help to pay for the upfront costs of installing the system through tax incentives. Additionally, power companies in most regions are required to pay you for energy that you have generated and not used. Yes, you read correctly, the power company will pay you!



Profitable



In most instances, 70% of the northern hemisphere can generate enough solar power to run and heat their homes with existing solar systems. This means that whatever is left over goes back to the power grid if you so choose. Just think of your power meter running backwards. The extra power you need for that cloudy day is stored in ever more efficient batteries. Most current users indicate that the use of solar systems only takes a little thought in power management.



Off the grid

Depending upon how you feel about the topic, one of the better reasons to use solar power is that you can take yourself off the "grid" so to speak. Many people don’t enjoy being a part of the social collective that is interconnectivity. Going solar takes you away from this one aspect of community and puts you closer to self reliance.



Versatile



Even though the solar power generation systems of today have come a long way to providing power, heat and a host of other services there is a long way to go. This is not to indicate, however, that solar power is not currently versatile in form and function. Solar panels can currently be formed into thin sheets to for car top electric powered cars. They can cover suburban rooftops and not be noticed, unlike those 1970’s units. Costs are also coming down almost as fast as the flat screen TV’s of today. Flat screens that solar power can power up through the use of a process called photovoltaic’s.



Personal responsibility



Past the cost savings and environmental benefits that solar power brings you should consider using it because you are part of a larger social order that will procreate. The human species has not been around for all that long and is doing its best to end its run in one way or another. If you would like to give your children’s children a better shot at continuing the human species run on this planet solar power is one small contribution that you can make all by your little self.

Solar Panels - The magic behind this environmentally friendly power source and why its sensible to buy them now

Solar panels can be used to harness the energy of the sun to some other type of energy. The power produced using solar panels will be available in the form of heat (to heat a building for example) or electricity which can be used to power anything from a small light, radio, computer, cell phone to a complete business.

Solar panels are a great way to cut energy costs and to lower your carbon emissions, and to become more self-sufficient. They are now becoming extremely popular in urban areas where alternative energy advocates and law makers are creating incentives for this friendly and quiet alternative energy source. The state of Colorado was one of the first states offering massive rebates on the up-front cost in acquiring and implementing a residential solar system. Other states are slowly following.

After the panels are installed, energy from the system will be used to power the house, or, when the energy  being made in excess of demand, diverted for use on the grid, where it is purchased back by the electrical power company. There may be times when you  actually can make money from your panels. With rebates factored into the initial cost it will generally take from fifteen to twenty years to get back the initial expense, at which time you will essentially be generating power from the sun at no cost. If the prices of solar panels drop it will be even sooner then that.

One little-known fact, however, is that solar panels are initially contributory to greenhouse emissions because it takes power to manufacture a solar panel, that this energy is very often fossil-based, and front-end loaded, and that therefore there is a time period during which the solar panel has actually added to carbon emissions rather than detracted from them. Until such time as the solar panel has produced energy equivalent to the energy used to manufacture it (its fossil-emission payback period) it is actually a contributor to greenhouse gas emissions. This fossil-emission payback period is generally considered to be five to ten years.

Low power solar panels are normally available in 12 v or 14 v configurations, while high power panels are available in 24 volt. As solar panels are DC, you will usually need a power inverter that changes it from low-voltage as Direct Current (DC)to another-voltage Alternating Current (AC) to change it to be compatible with the voltage and type that feeds both the home and the grid.

Conventional solar panels are constructed using twin sheets of semiconducting silicon, combined with phosphorus and boron atoms. Amorphous silicon solar cells are a highly powerful, emerging array of photovoltaics that differ in output, structure, and manufacture than traditional photovoltaics that use crystalline silicon. The H-AS solar panels are produced in the same way, but they are made just 1 micrometer in depth by laying down polymorphous silicon at very high pressures and temperatures.

Solar panels are normally maintenance free and many manufacturers will supply a guarantee of electrical output often for as long as 20 years.

Solar panels are installed on whichever side of your house that gets the maximum exposureto the sun. In areas south of the equator this would be the north-facing, and in areas north of the equator its the south-facing aspect.

Formula to Estimate How Many Solar Panels You Need

If you are interested in solar energy and are wondering whether or not you can


afford to install a solar electric (or photovoltaic, PV) system in your home, you

will need to know how many solar panels it will take to deliver the electricity you

need. The reality is that there are several variables that affect the size of the

solar electric system you will need. Each system has site-specific requirements,

and there is no one-size-fits-all answer. It is much more complicated than it

seems, especially if you are planning a system that will provide 100 percent of

your electrical energy needs.

But if you have just started your exploration into the possibilities of adding solar

panels to your home, you probably would like to have at least a ballpark

estimate of how many panels your project would need. So here is a way to

calculate a very rough estimate (emphasis on "very rough") of the wattage that

your solar array will need to deliver using a few basic numbers.

Formula to Estimate How Many Solar Panels

This is a basic and rough formula you can use to estimate the number of solar

panels your house would need, based on your family's history of energy

consumption. Detailed explanations follow, and there is a blank worksheet you

can print out at the end of this report:

1 Average daily kilowatts of electricity used (from utility bills)

2 Multiply by 1000 (kilowatts x 1000 = watts)

3 Multiply by percentage to be provided by solar

4 Divide by solar insolation value

5 Multiply by 120% (to allow for normal energy loss within system)

6 Divide by solar panel peak wattage (per manufacturer)

7 Equals Number of solar panels needed (round up to next whole Number)
