Converting To A Solar Home

Filed under solar electricity

There are many affordable options to convert your home into a solar home and solar energy technologies can supply for several different uses in a solar home. Passive solar design can provide heating, cooling and natural light for your home. Solar electricity options are available to power home appliances and solar water heating can provide hot water options for laundry and general household water use (showers, cooking, cleaning). When planning a solar home it is important to consider which solar energy options are most efficient, and cost effective for your situation.

A passive solar home utilizes home design to provide heating, cooling and natural light without the use of any special equipment. A passive solar home basically uses the environment to accomplish great reductions in energy use. A passive solar home uses construction materials and design to utilize the sun’s heat during winter months and block the sun’s heat during summer months. There are several passive solar techniques you can use in a solar home, direct gain, radiant heat from sunlight passing directly into a living space and being absorbed by furniture, flooring etc and usually achieved with south facing window installations, indirect gain, involving an attached Trombe wall that collects heat and distributes it throughout the home by the use of fans, thermal mass, which are materials that naturally collect and store heat such as brick or stone, and passive cooling, which generally includes overhangs for south-facing windows to block the sun during summer months for cooling the solar home.

Another feature often found in a solar home is the use of solar electricity. Solar electricity is generated when photovoltaic cells are used to absorb sunlight and convert it into usable electricity. The energy produced by solar panels must be converted to DC (household power) through the use of an inverter. Solar electricity can be used to supplement metered electric already being received by a solar home or with the use of a battery storage bank, can be used as the only electric source for the home. If the later is going to be used, it is suggested that owners of the solar home have a generator available for backup power.

Solar water heating is one of the most common uses of solar energy in a solar home. There are two kinds of solar water heating available for solar home use. The first is a closed loop system, which can be used in areas that are not prone to freezing. These systems use water filled tubes that are heated directly by the sun. A closed loop system uses an anti-freeze type liquid to collect heat from the sun and then the heated liquid is used to heat household water via a heat exchanger.

Regardless of which steps you take toward converting to a solar home, energy efficiency is the most important attribute to a successful solar home operation. Energy efficiency minimizes the need for heating, cooling and electricity. Using higher insulation levels, more energy efficient windows, appliance and lighting than used in traditional construction, you will already be saving yourself a lot of money and energy. However these changes may not be an option when converting an existing home into a solar home, so make any changes possible to your home energy efficiency and adapt other solar practices to convert your existing home into a solar home.

Solar Energy Panels For Home or Business

Solar energy panels have become more affordable in recent years making it a viable alternative energy option for savvy home owners looking for savings on their monthly utility bills and the environmentally conscious who also enjoy the financial advantage, but focus more on the benefits solar energy panels have on global warming and independence from fossil fuels.

If you are a beginner to the solar electric world, then you may be wondering what exactly solar energy panels are? It is really simple and yet fascinatingly complicated.  Solar energy panels are also known as photovoltaic panels; photovoltaic meaning electricity from the sun.  Solar energy panels work by collecting protons from the sun, which displace neutrons, and create a flow of electrons or electricity.  An inverter converts the power generated by the solar energy panels from an AC current to a DC current making it usable in homes as a direct electricity supply.

You can use solar energy panels to heat your pool, workshop tools, greenhouse lights and fans or depending on you personal electric usage, your entire home or business.  Most solar energy panels are designed to last 30-40 years and require little to no maintenance.  Over the life-span of solar energy panels, the energy savings realized by the owner is enough to justify the initial cost of the system and prices are dropping more and more as a larger number of consumers express interest and make the change to solar energy panels or other renewable resources.

Solar energy panels for small applications can be purchased at your local hardware stores.  These small versions are ideal for outdoor lighting, small water pumps and other outdoor tools.  If you are purchasing a home size or business size system of solar energy panels it would be best to seek out a local retailer of solar energy panels or a green energy retailer in your area.  There is also plenty of information available online about different solar energy panel providers.

Understanding the value of solar energy panels is the first step to becoming fossil fuel independent.  As our traditional energy resources are falling into exhaustion, now is the best time to look in to solar energy panels for your home or business.

What to Know Before Purchasing Home Solar Electricity

Filed under Live off the grid

Getting home solar electricity is more affordable today than 10 years ago. In fact, many state governments are currently offering tax rebates to persons that choose to convert to home solar electricity. If installing a photovoltaic system to supply your home solar electricity is too far out of your financial abilities, there are also programs available to purchase your utilities from an accredited green energy supplier. Green energy suppliers offer only utilities fueled by renewable resources, such as solar electricity, hydroelectricity and wind generated electricity. However, if you made the decision to switch to solar electricity for your home it is important to determine your electricity needs before you start shopping.

The first thing to determine is how much power you will need from your home solar electricity system. Different arrays and solar panel set-ups offer different wattage outputs. Take the time to determine your average daily electricity usage. You want to achieve a number that includes the entire year and affords for the different amount of energy used during winter and summer months (more lights, heaters, air conditioners).

When shopping for the right photovoltaic system to supply your home solar electricity definitely research the quality of the product. A product offering 13% efficiency and a lifetime warranty will be far more valuable than the panel offering 15% efficiency and a one-year warranty. Ask neighbors, friends and even strangers currently using home solar electricity, to learn more about the differences in systems. Sufficient time should also be spent interviewing installers and researching manufacturers as well.

A final decision needs to be made as to what kind of system you would like to use to supply your home solar electricity. There are generally three types of solar panel systems used to supply home solar electricity. The first type is a grid-tied system in which your solar panels are tied into your current power meter. You are using both electricity supplied by your panels and your supply is then backed by electricity from your electric company. The second available solar panel system for supplying home solar electricity is a grid-tie with battery backup. With this system you are collecting electricity from you panels, filling your batteries for emergencies and then the excess is sent back to the electric company through your meter. The final system is a stand-alone system. Very similar to the grid-tied system with battery backup except that you are completely disconnected or maybe never connected to a major utility provider for your area.

Once you educate yourself on providing your home solar electricity, you are probably ready to start shopping. Remember that converting to home solar electricity is an investment and you will reap the rewards over time. And don’t forget the pride you will have with reducing your carbon footprint by converting to home solar electricity.

Use The Power of The Sun With Solar Electricity

Filed under solar electricity

When asked about alternative energy or renewable energy, most people think of solar electricity. Generating electricity from the sun is a technology that everyone knows well. Whether it is your pocket calculator, home, or workshop, regardless of your power needs, solar electricity can get the job done.

Solar electricity has a number of unique advantages over conventional or grid-based electricity. Solar electric systems can be designed for a variety of applications and are extremely beneficial in remote areas where other electric opportunities do not exist. In addition, photovoltaic systems that generate solar electricity have no moving parts therefore requiring minimal maintenance, are easily expandable, and with many smaller units, transportable.

Environmental compatibility is a huge selling point for converting to solar electricity. The fuel for generating solar electricity is a free renewable resource, the sun. Solar electricity offers no noise pollution and actually almost no pollution from their operation. Another appealing factor for many who choose solar electricity over conventional electricity is simply the independence. It is an attractive offer to many rural dwellers to know that when the lights go out due to storms or blackouts, theirs are still working. No longer a slave to waiting on hold to report an outage to find it will be 10 hours before their service will be restored.

The hardest part of converting to solar electricity is the cost of the system. Investing in a solar energy system can be a substantial upfront cost. The value of solar electricity is realized over several years. A professionally installed solar array for an average dwelling (avg. $100/month in electric bills) could pay for itself in 5 years. You could reduce that number by building your own solar panel system or by purchasing a used system. With many solar energy systems in less rural areas and only in some states, you can sell your unused solar electricity back to the electric company. In these situations the return on your investment is realized much more quickly.

Using the power of sun with solar electricity is a benefit to the environment and to your home. Solar electricity is already being used to supplement power for a number of large cities in North America. Take time to learn more about solar electricity and how you can have trade in your electric bill for a carefree life with solar electricity.

Why Choose Renewable Wind Energy

Filed under wind power

Renewable wind energy is the fastest growing source of power of any renewable energy sources and technologies. With renewable wind energy, the flow of air turns wind turbines to create electricity. As the speed of the wind turning the turbines increases the amount of power the turbine produces increases as well. In areas where winds are strong, renewable wind energy is a smart choice for providing power to homes and businesses.

Even if you don’t live in a windy area, you can still supplement your current electricity supply by utilizing renewable wind energy. The best part is by using do-it-yourself guides; even the least skilled handymen can build their own windmills and start using renewable wind energy to lower their electric bills each month. However, if you do live in a particularly windy area you can feasibly generate an abundance of electricity from renewable wind energy systems.

It is also conceivable to build several wind turbines to power your renewable wind energy system. Most of us have seen the pictures of the wind farms being built to supplement power to whole cities. This is a little much for a homestead, but even small dwellings can benefit from multiple smaller wind turbines. In many states, it is possible to sell the excess electricity you generate from your renewable wind energy system back to the utilities companies.

The very best part of integrating a renewable wind energy system into your home or business is the environmental impact. Renewable wind energy produces little to no pollution, no harmful greenhouse gases and no methane or carbon dioxide-which contribute to global warming. And of course the savings those homeowners can realize after their initial investment in renewable wind energy.

It is definitely worthwhile to learn more about renewable wind energy. By building your own wind turbines you can add needed dollars to your pocket and help the environment at the same time. Renewable wind energy. Free power from the wind. Sounds beautiful, doesn’t it?

Off Grid Living-You Can Do It Too

Filed under Live off the grid

More and more people are realizing that you can still enjoy modern amenities while enjoying the independence of off grid living.  Being off the grid means being exactly that, off the grid.  No power lines, no electric bills, and being free of utility grid demands, not to mention their ever-rising rates.  Off grid living is environmentally friendly and cost effective and it is an option available to almost any one owning a home.

The principles of off grid living may be applied to any home in the world, even those currently tied to the grid.  From solar panels, hydropower and windmills, there is growing curiosity in off grid living and breaking free from fossil fuel burning power plants.  The technologies have advanced and the costs have dropped greatly.

Even do-it-yourselfers can take leaps into off grid living with many kits, resources and manuals available for instruction.  As energy demands increase globally, those living off grid can rest easy knowing their own energy costs are diminishing.

The idea of off grid living can be scary to some who believe they will have to give up some of their most prized possessions and electronic gadgets to achieve such freedom.  This is very far from the truth.  Off grid living is simply about learning to moderate your use of electricity.  It can be as simple as turning off lights that are not really in use.  Purchasing appliances that don’t use energy when not in use (like clocks on microwaves and stoves).  Learning to unplug, not just turn off.  Things like computers and printers, well anything with the little green light that is always on, these items are stealing precious energy and adding to your bill.  Wanting to become part of the off grid living adventure, doesn’t always mean giving up everything, sometimes it just means getting smarter about the things you have.

Off grid living has gotten so popular that even completely re-locatable high efficiency homes are being produced to meet those needs.  Very similar to mobile homes and travel travelers in layout and definitely only designed for a one or two person dwelling, these housing units use solar power, passive solar design and a small amount of natural gas to provide off grid living that you can take with you when you move.

If you are interested in off grid living, but need more success stories to drive you over the teetering point then start your research on the Internet.  There are tons of great resources available and individuals who took the plunge into off grid living with great success telling their stories.  Imagine, no more gathering around that one little candle when the power goes out, or having the neighbors over to watch their favorite shows when there is a blackout.  Off grid living is obtainable for anyone and you too can enjoy the life of off grid living no matter where you make your home.

Solar Electricity, Right For You, Right For America, Right For The Planet

Filed under solar electricity

Solar electricity systems are a reliable pollution free energy source. If you are installing one then you are joining millions of others around the world in doing something for yourself and the planet. These systems are becoming more and more affordable as photovoltaic designs are improving. An added bonus in several states is the ability to feed power back to the grid at times when you produce more power than you use – you get to make your meter run backwards and that can be exciting.

The building block of solar systems is the photovoltaic cell. It wasn’t that long ago that these were curiosities that showed up at the science fair running a small motor. Now banks of them on your roof or other exposed area can power your home. Electricity produced by the cells typically charges batteries which then pass through an inverter to make the AC required by the lighting and appliances in your home. The batteries provide backup to supply power when there is no sunlight. How exciting is this – making your own power?

A solar power system can come with an initial high price tag. It may take years before you recover the cost. However if your state allows feeding back to the grid and with tax incentives and rebates your system will pay off much more quickly. A solar electricity system will never run out of fuel nor will it increase our dependency on foreign oil. But don’t think about the costs or that you will be saving money down line, think of it rather as investing in your freedom by starting your research of solar electricity systems today.

Can Anyone Live Off The Grid?

Filed under Live off the grid

Living off the grid is available to everyone. New technologies make power generation of such level that no modern convenience need be given up. No need to live like granola loving hippies (unless you want too). There may be a larger investment for high energy appliances like AC, chest freezers and the like, but these things are easily powered off the grid.

The demand for renewable energy has caused more efficient and easy to use components that will allow you to live off the grid if you are willing to pay attention to your energy consumption. It is a simple matter to use renewable sources to make electricity. You need power – sun, wind, or water whereby you make a low voltage DC that you convert by an inverter to usable AC or house current. The excess power you make is stored in battery banks where it can be retrieved during high demand times or where the direct energy source is not available (after dark for a solar system).

This entire process is largely automated. Except for maintaining the batteries there is almost nothing to do as long as you make sure you continue to operate within the capacity of the generation. The secret of success is making sure you have planned your system to match or exceed your energy use.

It’s fun to use all that power and not get an electric bill. Energy freedom is great and you combat global warming. Recently a storm took out power lines in nearby neighborhoods. People were without power for four and five days. People who live off the grid did not share this unfortunate condition.

It is important to conduct your research and determine which alternative energy sources will work best for you in your geographical area, but it is definitely worthwhile to learn how to live off the grid and feel the rush of freedom being off the grid can give.
