[S704]Solar Power For Residential

by Wilhelm Williams, Wil

What can a homeowner do to reduce the electric cooling bill? One option is to raise the thermostat, at the price of comfort. Perhaps consider installing more insulation in the attic or having double pane windows installed. Each of these choices will increase the energy efficiency at considerable investment cost. However, these and many other energy efficiency options will help reduce the energy demands of the home but will not counter to rising cost of electricity.

There is a rising interest in harnessing solar power for residential use. Despite the high initial investment, the long-term savings are being touted as an efficient means of beating the high cost of electric power. Look into local, state and federal tax incentives to help reduce the investment cost.

There are two main components to a solar power system.
• Solar panels forming an solar array
• Inverter to convert the 12V or 24V DC electricity into 120V AC.

Optional components are:
• Charging controller
• Storage batteries

The battery array is charged by the solar power system. During the night or on cloudy days the batteries discharge the electricity and provide power to your home. The charging controller charges the batteries and prevents an overcharge that would shorten the lifespan of the batteries.

Storage batteries do not need to part of a residential solar power system. Any electricity that is generated and is not needed to power the home can be sold back to the electric utility company. In effect, your home becomes a mini power generating station for the electric company. How would you like to see your electric meter run backwards?

How does a solar power system work and integrate into my home's electrical system?

Solar panels convert sunlight into electrical energy. A solar panel's electrical output is affected by a couple factors: angle of the sun light to the solar panel, number of hours of direct sunlight, and the efficiency of the solar panel. It is interesting to note that currently available photovoltaic solar panels convert about 12 percent of the sun's energy into electricity. Although, this does not appear to be very efficient, this is a four times greater than what was available a few years ago.

Solar panels are connected into a grid often referred to as a solar array. The panels are connected electrically to increase the amperage. The solar array is mounted on the south facing side of the roof at an optimal 30 degree angle. The ideal location should be free of any obstructions such as building and trees for most if not all of the day.

If you choose to install storage battery pack. The electric lines from the photovoltaic panels will be connected to the charge controller. The storage batteries are similar, but not the same as an automotive battery. They are deep cycle batteries that can handle being charged and discharged thousands of times before the battery needs to be replaced. They are also known as sealed lead acid batteries or gel cell batteries.

The final piece is the inverter. The inverter converts the 12 volt DC electricity into usable 120 volt AC. The inverter is directly connected your home's electric system at the main breaker box via a junction or sub panel. Inverters have been around for years in commercial applications. Now days they are most popularly used to convert 12 volt DC electricity from a car battery into 120 volt AC power.

Advantages of solar electric power

Solar power for residential use has several obvious and not so obvious advantages for the homeowner.

• After the system has paid for itself in electricity it generated that you did not need to purchase, the solar power system continues on producing free electricity for your home.
• Reduces the heat build up in the attic. Each solar panel installed on your roof will shades your roof from the sun's infrared energy. A cooler attic reduces the amount of cooling required for a comfortable home.
• It quietly produces electricity.
• 100% renewable energy source
• Pollution free electricity production
• Most solar panels are warranted for a minimum of 25 years.

Disadvantages of solar electric power

• Replacing the roofing material creates hassle in that the solar panels must be removed from the roof while the old roofing is removed and the new one is installed.
• The high investment cost. A typical installation costs about $13,000.
• To regain your investment, you have to live in the home for several years. This depends on the amount of electricity produced and the cost per kilowatt purchased from the electric company.

It will be necessary to have a local solar power installation company design the right solar power system for your home. Carefully interview and compare each installation company before selecting the design and installation company.

A growing number of homeowners are turning toward the sun to convert its energy into clean, renewable electricity to meet the power demands of their home. Isn't time you considered converting free sunlight into electricity for your home?

Water runs dark, trees are dying and the air we breathe gets thicker and thinker by the moment. There are several solutions to these problems, but oddly, the source that got the whole thing going may actually be the answer to solving the poor choices made for the planet. Solar power got the entire process going and may be the solution to getting it back on track.

In its intentional use, solar power gave us heat and light. As evolution worked its magic solar power was not an alternative source of power, it was –the- source of power as it warmed the earth and moved the air. Now, our “modern" technology has evolved to a point where we can once again use solar power to warm and move our air. But why should we use solar power when the same planet that gave us the sun gave us the coal to accomplish the same task? There are many reasons, and most of them are of the kind that people can identify with; they are self serving and entirely hedonistic.

Solar leads to cost savings

All one has to do these days is open up an electric and heat bill to see how much it costs to heat and light your home. Solar power is a great way to just about eliminate the costs associated with lighting and heating your home. For those that are using solar powered heating and lighting equipment today there is little if any cost associated with heating and lighting their homes. Yes, there is an up-front cost to installing these units but pay back times through cost savings and tax credits are getting shorter and shorter due to better technology and awareness. These current users report that they actually make money from using solar power systems just by paying a little closer attention to how they use the power that they have. For the most part, they indicate that a 30 second glance at back-up batteries for piece of mind is all the extra time required to start saving money.

Money maker

Some may say that piece of mind doesn't go very far when it comes to a series of cloudy days. Batteries, they say, can run out or get low. From all reports, however, cloudy day issues, in a majority of the world’s climates, are not an issue. In fact, a majority of users find that they have an excess of electricity that ends up just going to waste. Or so most people- once - thought. Although the entire US is not quite there yet most sates require that utilities buy back excess power generated from those desiring to remain on the power grid. Although it may sound a bit odd, solar power users find that their electric meters actually run backward quite a bit of the time when solar power systems are in use. God forbid there were a few weeks of nothing but clouds and cold, but if there are the owner is free to use the power that they sold back to the utility. Past the home front, add a water wheel and a wind mill and you have a nice little income generator with the electric utility paying you.

Off the grid

There is a certain segment of the population that just does not want to be connected to the “grid", as the power and information society calls it. For these people solar power is a great option. Solar units are fairly low cost and getting lower cost every day. They can also withstand a 1" hailstone traveling at 50mph. For survivalists or even for a farmer that needs to irrigate his crops in the middle of nowhere, solar is the way to go.

Develop a new technology

Man at his basic is a curious being. What if? Is always being thought about whether it’s just a casual thought during the day or figuring out how to get to Mars. Advancing technology is just who man is. Using solar may satisfy our current environmental issues but it also satisfies our intellectual needs. If solar power isn’t used it won’t advance and our need to know won’t be satisfied. Intellectually, solar is a great idea.

Leave the world a better place

Throughout time man has found a way to screw up the planet in one way or another. Most of the time, man has screwed up because of ignorance or with good intentions. Using solar, at the moment, appears to be one of those good intentions. It may end up being a bad thing 200 years down the road, but for now, it may be one of the only ways to leave the world a little better then when we got here.
