The Upsides and Downsides of Residential Solar Power

Friday, May 22nd, 2009

Getting acquainted with all the pros and cons of home solar power before installing it is very important. A solar home can substantially reduce the need for fossil fuels and reduce your energy costs. Like with any investment into your home, you should thoroughly research the pros and cons of solar power.

Pros of Home Solar Power

Owners of solar powered homes these days can receive generous tax incentives from local, state and Federal government agencies. These tax breaks and credits can go a long way to reduce the initial cost of a home solar conversion.

There can be little to no cost for electricity once a home solar power system has been successfully installed and is up and running. One can even make money by selling power back to the utilities in many areas of the country.

Using home solar power and being off the power grid means that even when the weather is stormy and the power grid goes down there is still electricity at your house, assuming you have opted for a power storage system. Brownouts and outages frequently occur in the southwest of the US during intensely hot summer months often because people end up constantly using their air conditioners.

Another thing going for solar power is the available option of doing it oneself. With the help of the latest solar power conversion kits, and the books and information available, it is possible to switch your home to home solar power by doing it yourself. Do your homework, and make sure to get all the necessary permits.

Cons of Home Solar Power

The initial cost of converting an existing home to solar power keeps the option out of range for most homeowners due to lack of funds for such such an investment. However, the cost can be quite a bit less when incorporating solar power options into a new home when it’s being built.

It can be quite a daunting task and most often requires certified installers, permits and more complication to convert an existing home to solar power. In addition, there is quite a bit of research and paperwork a homeowner will need to do before getting started. Your local power company will need to send a representative to hook the system up to the grid as well.

Not all people in all places have access to solar energy. As long as the sun shines solar power can keep the batteries charged, but many homes in more northern states, homes without a good southern exposure, and homes with large trees or a building blocking the sun’s rays may not be good candidates for a residential solar conversion.

Converting a home to solar power can be a rewarding and cost-effective endeavor for many homeowners, but it’s not for everyone. Simply switching to a solar water heater could be an excellent money-saving option for some.

But it is likely that there will be many more home solar conversions done in the coming years, partly due to rising energy costs, dwindling fossil fuels and also, in large part, a result of environmental concerns associated with greenhouse gases.

Solar Powered Lights for your Yard & Garden

Saturday, May 9th, 2009

You may be wondering how solar-powered lights work. Solar lights are used after the sun has gone down. So how can they operate?

First of all, understand that lighting devices which relies on solar power generally use a backup battery to operate. Solar cells are used to charge the battery during the day, and the battery powers the light during the night. The solar cells might be attached to the device itself, or might be located nearby.

This type of lighting is often used in remote locations, where conventional power sources are unavailable, and lights can not be connected to the power grid. They are also used for outdoor lighting, or as landscape lights around the home or garden.

Components of Solar Powered Lights

There are four basic components of a solar powered light. Many solar lighting systems are sold with these components already integrated, but it is good to know what they are:

  • The lamp
  • A charge controller
  • The batteries
  • The solar cells

When purchasing solar lights, the majority of the cost involved will be for the solar cells. These are the most expensive parts of the device or system. Be sure your system is installed within some type of weatherproof housing, so that the solar cells and electrical connections will withstand the elements. Ensure that the electrical parts are protected from moisture at all times.

The charge controller is like the “brain” of a solar-powered light. It protects the batteries from overcharging, and maximizes the electrical output of your solar cell array. It also controls the duration that the light can operate. Without a charge controller, your setup will not function properly.

Uses of Solar Lights

Most solar powered lights are used to illuminate outdoor gardens and walkways. The lights are generally cordless, and you can move them around easily without the need to dig ditches and run the wires underground.

One disadvantage solar lighting has, in comparison to conventional lighting, is that its stored solar power diminishes over time. That means that while the light may be strong during the first few hours of operation, it will then gradually grow dimmer as the night goes on. This might not be seen as a disadvantage by some, because most outdoor activities occur during the early evening hours. Different solar lighting systems also have different capacities, and some last longer than others.

Keep in mind that solar-powered lights depend on the sun to operate, and their performance can be influenced by weather conditions. If the weather is cloudy or rainy, then the battery power will be lesser than it would be on a sunny day. There are also different levels of quality, where solar lights are concerned – the cheaper ones tend to be less efficient and do not last as long.

Hopefully in the near future, improvements in solar technology can make solar lighting less expensive, and more efficient, even during bad weather.

How Electric Power is Delivered to A Residence

Saturday, April 11th, 2009

You can find many advanced books on electricity generation that will give you tons of details. Really, there are entire college degrees that focus on electricity generation and delivery. If you are looking for extreme details on this, please check out your local library. If you are looking for the basics, read on.

Lets talk about what exactly electricity is before we start talking about how it is delivered to your house. Think of electricity as water flowing through a pipe or garden hose. The water is really electrons in the metal that makes up the wire. The hose is the wire that transports the water (electricity). There are all kinds of fancy definitions, but that is the basics.

After leaving the power plant, electricity is transported on power lines. Transporting electricity at high voltage is more efficient than transporting at low voltages. Power lines form a huge system or grid that attaches everybody’s house and business to the power plants. In the United States, virtually the entire country is attached to the same grid. Texas is almost separate, but there are still a couple ties into the rest of the grid. All power plants add electricity into the system so if one plant goes down, there is still electricity because the other plants just put a little more in.

The power lines deliver voltage to transformers (usually a series of transformers) to change (step down) the voltage to 120V for you to use in your house. Power comes to one point at your house before being split up to go to all your outlets and lights. This one common point is either a fuse box or a breaker box depending on how old your house is.

Traditionally, one electricity company took care of delivering energy to your house and you didn’t have to worry about picking your company. This was nice because it was one less thing to worry about. Unfortunately, this can mean you have to pay higher prices.

A new electric distribution model has emerged in the last few years. It is a deregulated business model where multiple companies (one such company is ambit energy) sell electricity and have to compete for customers. In this model, one company or set of companies owns the power plants while a different set of companies is responsible for selling the electricity. Some states like Texas, New York, and Illinois allow non-monopolistic companies to essentially buy electricity from the power plants and sell it to consumers. In the place of large companies, small companies even individual people become Energy Consultants and are making a ton of money. Instead of a few big companies making a lot of money, this allows a lot of smaller companies and individuals to make money.

There is another trend out there that could change the way electricity is generated, or at least the amount that is delivered. residential solar power is starting to save people a ton of money by generating their own power.

How would you like to generate your own electricity for less the $200 (£150)? – Get Important Tips

Tuesday, February 24th, 2009

There are different ways of making electricity for yourself. Alot of people use wind power and solar power. Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind turbine, wind power unit (WPU), wind energy converter (WEC), or aerogenerator.

Solar power is another common use of producing electricity. Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Alot of people nowadays are looking at ways i.e. wind power and solar power to produce cheaper electricity. With living costs getting so expensive nowadays, people are looking other ways to reduce their electricity bill or create their own source in their backyard.

There are many companies solar eclipse out there who would be able to help you get a grant static electricity or tell how to build a wind or solar farm.

Learn How to Make Solar Panels the Easy Way

Monday, February 16th, 2009

Electricity bills seem to be on the rise with no relief in sight. No wonder more and more people are looking into installing solar panels in an effort to save money. But, their enthusiasm quickly dissipates when they discover the price of professionally installed panels. It can be overwhelming, and puts solar power out of reach of the average home owner. However, you can save thousands of dollars if you learn how to make solar panels yourself.

Many of you may be thinking that you have to have some sort of engineering degree or be a DIY genius in order to make your own solar panel system. But nothing can be further from the truth. Learning how to make solar panels is a lot easier than you think. In fact, anyone can build their own solar panels, from teenagers on up, and you can do it in a weekend. Plus, you can build your solar panels for the fraction of the cost of what a pre-made solar panel system would cost you.

The other benefit of learning how to make solar panels on your own is that you have a lot more control over the size of the system. This means that you can create a highly scalable system that can fit your needs as they grow.

My number one tip before you even start your solar panel project is having a quality manual. And, don’t be surprised at how easily you’ll find the supplies you need. In fact, you’ll find most of what you’ll need at your local hardware store. I’m talking about stuff like plywood, rolls of copper wire, and sheets of glass. You can also find inexpensive photovoltaic cells for your project quite easily, either over the internet at places like eBay, or from local retailers.

It won’t take you long to make your solar panels. The average, inexperienced do-it-yourselfer can make their own 100-Watt panels in about a day, provided they have all their materials at hand. 100-Watts may not sound like much, but you’ll be able to power some of your smaller appliances, or perhaps even your workshop so you’ll be able to build more solar panels and your first panel will provide all the power! Now that’s pretty cool.

But, before you begin, you must get your hands on a good, quality manual that will provide the detailed instructions you need. It should be able to teach you how to make solar panels even if you’re not very mechanically inclined. Don’t forget the old adage that you get what you pay for so don’t skimp when you’re ready to purchase your manual.

The final cost of making your own solar panels is pretty low so you can afford a quality manual. I won’t lie to you. Making your own solar panels isn’t easy, and will take a bit of effort, but with the right manual you’ll be on you’re way to learning how to make solar panels to meet all your energy needs in no time. Then sit back and relax the next time the power goes out on your block. You’ll be the only one watching TV, and heating up food in the microwave while everyone else is eating a canned dinner by candlelight.

Yes, a professionally installed solar panel systems can cost thousands. Who has money to spare in today’s economy? Make the choice to go “solar” today, and learn how to make solar panels on your own. You’ll be saving money, and the environment. For more information, visit http://renewableenergyathome.info.
