wondering what is homes off the grid? in this article you’ll get a clear definition and how to turn your home to be “off the grid” too.

If you’ve been to Alaska, Hawaii or any of the truly remote areas of the world, there is a good chance you have encountered homes off the grid. Be it by choice or because there are no commercial power providers in the area, many people end up with their homes off the grid and have to provide their own electricity, water, sewage etc.

Homes off the grid, or OTG, are able to operate completely independently from the utilities that the average person has usually come to expect and take for granted.

Electricity, heat and water can often be provided by creative applications of alternative energy sources.

Wind turbines and solar panels can provide electricity to heat, light and pump water into a home.

A windmill can also be used for direct mechanical force to pump water into a raised water tank for a house to be used at will. Rainwater can be harvested for the same reasons.

In some locations, homes off the grid may even be able to take advantage of geothermal energy for any number of uses, such as heating the home, water, and creating steam power.

Living off the grid does not necessarily mean that these alternative energy and utility solutions need be applied at all. Water may come from a lake or stream, while light and heat could be provided just using a wood burning stove and candles.

If electricity is desired, these same streams can provide hydroelectric energy using small generators, a setup not so different from the windmills used to grind corn into meal in ancient times.

Many people are trying to build homes off the grid in order to be more environmentally friendly. In an age where fossil fuels are being consumed at an alarming rate that is causing any number of different devastating effects on the environment and climate, homes off the grid using the various alternative and renewable energy sources and construction methods available today are doing their part to insure a cleaner, healthier tomorrow for the rest of us.

Regardless of the impetus to build them or live in them, homes off the grid are an amazing exception to the norm, and a valuable source of ideas and constructive creativity for anyone interested.

1. 1. What is solar energy?

Solar energy is the use of the sun’s rays to generate either heat or electricity.

1. 2. How do solar photovoltaic cells/panels work?

Using a semiconductor material like silicon and added elements of boron and phosphorus, a solar cell creates a conductive environment that allows electrons to move across it when activated by energy from the sun’s rays.

1. 3. How much can I expect to spend installing a solar power system in my home?

A system that provides 2000 Watts can cost around $20,000. That is without a battery bank, and including the panels, mounting and inverter. Remember that there are various Federal and State tax breaks to offset and sometimes completely absorb this cost.

1. 4. How much money can a solar power system save me?

Not only can you save 60-100% of your utility bills (based on your home’s electricity usage, system setup, location and season), but selling renewable energy credits through a broker to your utility company can actually make you money!

1. 5. Will my solar power system require regular maintenance?

No. The only necessity is insuring that your solar panels are free of any obstruction from the sun, such as leaves or snow.

1. 6. Are there any special permitting or insurance requirements for installing a solar energy system?

You will need a building permit to install your system, and following electrical, plumbing and building codes, as always, will be required. Also, you will probably have to sign an interconnection agreement with your utility company.

1. 7. Can I install my solar photovoltaic panels and system myself?

Absolutely. There are a lot of resources out there to help the average homeowner upgrade their home to benefit the environment and their wallets. For starters, National Electric Code Article 690 will inform you of the legal standards that need to be met.

1. 8. What are the components of an average residential solar panel kit?

A solar power system is comprised of the solar photovoltaic panels themselves, whatever mounting equipment is required depending on your mounting method, a voltage inverter and a net meter that will keep track of how much power you are using or feeding back into the grid. This is assuming you are on the grid; a system off the grid will not need a net meter. It will, however, require an array of batteries, as will any system that is intended to run when there is a power outage on the grid.

This article is to give one a basic outline on how to build a wind turbine at home.

There are some very basic parts and some more difficult ones involved in such a system.

The fairly easy parts are the blades, the tower and the motor. Some people will endeavor to make their own DC motor, but for the sake of sanity, and because it won’t cost you any less to just buy a used one, we’ll stick to purchasing.

Jump on EBay or Craigslist or whatever place to buy used things catches your eye that day. Maybe your uncle owns a scrap yard or maybe you are a DC motor dealer yourself. Either way, obtain a permanent magnet DC motor that is rated for high DC voltage/high current at a low rpm. You want it to produce at least 12 volts DC at an rpm attainable by your wind turbine, say 300 rpm. You should be able to find one for less than $100 if you shop around.

If you still want to know how to build a wind turbine at home, head on over to your local home supplies store. You’re going to want to pick up a 24 inch long piece of 6-inch PVC pipe, a piece of sheet metal about 12 inches by 10 inches, and a 3 foot piece of 2×4 wood. Keep it cheap! Also, grab a piece of PVC big enough to protect your motor and some clamps to strap it to the 2×4. Any sort of housing will do, maybe even an old mailbox!

Attach the housed motor, shaft end out/wires in, to one end of the 2×4. Screw your piece of sheet metal to the other end. This will act as a tail to keep your turbine facing into the wind.

Now for the blades. This is a bit tricky. Are you sure you’re still curious how to build a wind turbine at home? Jeez, you can’t be stopped!

Cut your 2 ft PVC pipe lengthwise into quarters. Take a 5cm by 5cm rectangle out of one end (this is the end you will bolt to your turbine), and then taper down from the edge of the missing rectangle (5cm in) to the other end, ending your taper one inch above the end corner instead of making a point.

Do this to each quarter of PVC and you have four blades.

Find a hub that will fit your motor’s shaft at a scrap yard, or just take a decent hub of aluminum to a shop and have the desired hole cut. Now drill holes and fit your blades to the hub. Fit the hub to the motor shaft and secure it.

You have now gone almost completely from not knowing how to build a wind turbine at home to being quite capable.

Drill a hole in your 2×4 where your tower/mount will fit. Insure that it is at a point of good balance for the turbine assembly, probably closer to the motor. This is where you will run the wires down to your electrical controller and power system. Whether you have batteries and are off the grid, want to attach your rig to a 100 ft tower, or just mount it on a pipe to the top of your residence, you now know how to build a wind turbine at home. The next step is up to you!

Hello there, stranger. Do you have an hour? One hour?

If so, it’s time for us to sit down and make some homemade solar cells.

You might be thinking that I’m crazy; that solar cells are expensive constructions of silicon created in enormous factories using high temperatures and vacuums.

Here is where we provide an alternative using commonplace materials that you can pick up at your local hardware store. The name of the game is ‘cuprous oxide’, a material that has photoelectric properties.

With it, we can make our own homemade solar cells.

We will need a square foot of copper sheeting. Two small alligator leads, a multimeter that can read down to 10 microamperes, a good electric burner on a stove or otherwise, a large-mouth glass jar or plastic bottle with the top sheared off, sand paper and shears to cut the copper sheet in half.

Trim the sheet to a square the size of whatever burner you’ve come up with. Now wash your hands and the copper thoroughly. There can be no grease or corrosion. Sandpaper the sheet as well, just to be 100% sure.

Place the metal on the burner and crank it to its highest setting. If it goes to 11, do that.

The copper will heat and turn into an iridescent maddening water color. Let it go.

We need it to cook for at least 30 minutes, so that the black crust that forms on top is good and thick.

Now shut it off and leave the copper to cool slowly.

How is this helping us to make homemade solar cells? Be patient!

As the metal cools, the black crust will spring off of the copper and make a mess. Let it go. After 20 minutes, give the copper a light scrubbing under running water to remove any loose bits. Don’t get too crazy; we don’t want to bend or cause any trauma to the copper in any way.

There will be a delicate layer of red cuprous oxide left over.

Here’s where it all comes together. Place your burned red copper sheet as well as the other unburned half into the bottle or jar, gently bent to hug the walls, so that they do NOT touch. Now connect your positive alligator lead from your multimeter to the clean copper plate, and the negative to the burned cuprous oxide one.

Fill a pot or some other container with enough hot tap water to fill your container. Now stir in several tablespoons of salt until it dissolves. Take this solution and pour it into the jar or bottle with your copper plates until it is one inch from the top of the plates. The electrical leads cannot get wet!

Now watch your meter. The amount of electricity generated is miniscule, but move the battery you have crated into the light and watch your power increase!

It would require a houseful of these homemade solar cells to power the house itself, but the experiment and the logic are valuable and a good start towards understanding solar power and alternative energy sources in general.

Are you serious?

Do you really want to cut your electricity bill up to 95%?

So you want to know how to build a homemade solar panel?

Using a lot of materials that you may have just sitting in the garage collecting dust, this is actually quite simple. Some steps are tricky, but if you just step back a moment and apply a bit of logic, it all becomes clear.

You’ll need basic woodworking tools, some screws, a strong adhesive, and some wiring and soldering materials. Yes, unfortunately soldering is required, but everyone has that electrical guru friend

The most crucial material to making this work is to get online and find some cheap solar cells online.

As you are not going to be making any silicon-based products in your home any time soon, these basic building blocks will be necessary. Solar cells with minor flaws are just fine and often much cheaper.

You’re going to want to buy enough cells that you can wire them in series to get to about 18V, which is what you need to charge 12V batteries.

In an ideal world, you will also have a bank of 12V batteries (like car batteries) that you are storing your collected energy on, then inverting it to AC for use in your home or otherwise.

Be sure to get solar cells with “tabs” on them, or metal strips hanging from the positive and negative conductors for easy wiring and soldering!

There are a lot of small .5V cells out there, 36 of which, wired in series, produce 18V. It is better to charge batteries with a smaller amperage current, or ‘trickle’ charge, for longevity’s sake, but if you have other plans for the solar panel/panels, be sure to get some that meet your needs.

Anywhere you buy them you should be able to give you detailed specifications, but as a general rule, smaller cells produce less current.

See how much you’re learning? Aren’t you glad you decided to learn how to build a homemade solar panel?

When you receive your solar cells, be gentle. These are not rugged apparatus. They are brittle.

Lay out your 36 cells (or however many it will take to do the job you need done) in a square with as little space between them as possible so that you may solder them together. This is the size of solar panel you will need to build.

Construct a housing for the cells with the following in mind:

1. The panel needs to be weatherproof.

2. There need to be vent holes all around for air pressure equalization and to prevent condensation. The holes must not allow critters/insects in, so block them with insulation or something similar.

3. Leave room for the few wires that will need to be run from the positive terminal of the cells run in series and the negative. These wires will run out of your panel to a connector of some sort where you will connect to your batteries.

4. The whole point is to get as much sun as possible. With that in mind, the housing should not be deep at all, and any trick to allow more sun in or focus the sun is a plus!

And now to bring it all together, the last step, and you will know how to build a homemade solar panel.

Solder the solar cells in series and/or parallel to achieve the desired voltage.

Affix the solar cells, in the original pattern you laid out, to whatever housing you have constructed. Insure the proper wiring is run and secured as well, and seal up your solar panel.

Before sealing it, you may want to hook up a multimeter and verify that you are generating the desired power.

A final note is that you should have a blocking diode between your panel and your batteries, to assure that your panel does not discharge your batteries when not generating power.

You are now qualified to teach others how to build a homemade solar panel, and thereby make the world a cleaner, more efficient place!

Solar photovoltaic systems use silicon solar panels to generate electricity using sunlight. Although used in any number of configurations and functions, they are primarily used to offset energy costs in homes that are connected to the grid. Heat is not involved, as one may think. Instead, the reaction between the sun’s rays and the semiconductor material being used frees electrons which are harnessed into an electric current.

Noiseless, no pollution and, in most cases, able to be purchased from a local manufacturer, solar photovoltaic systems are the ideal alternative energy solution for any investor. Multiple solar cells are connected to form a solar module, which can output between 10 and 300 watts.

The solar photovoltaic systems will be comprised of one or more of the aforementioned solar modules which are connected into a system and ran into an inverter.

Voltage inverters convert solar photovoltaic systems’ direct current (DC) outputs into an alternating current (AC) usable by a home electrical system.

Another optional component is a set of batteries to store energy in case of a grid power outage, or if you plan on living “off the grid”, or completely independent of commercial electricity.

A primary consideration in purchasing solar photovoltaic systems is the initial cost versus the long-term benefits. How long will it take to justify your investment? How much will you be saving per month on your utility bills?

Many will note the low costs of commercial energy versus how much you will pay for your solar system, but it is good to keep several things in mind.

First, there are many Federal Tax Benefits in place that pay 30% of the install cost of solar photovoltaic systems.

In addition to that help, many states also have programs that will help and sometimes even completely defray the costs of setting a system up.

The solar system will add value to your home, so that if you ever decide to move, the install may pay for itself then and there.

These benefits don’t even take into account the fact that you are reducing your monthly utility costs by 60-100%, helping the environment immensely, and that you can sell renewable energy credits to your utility company through brokers for thousands of dollars each year just by generating the solar power for your home. Utility companies have a Federal obligation to buy a certain amount of these credits each year.

Solar photovoltaic systems offer an enormous potential not only for savings, but often for profit, and you are doing your environment a great service in the meantime.

Whether you are a do-it-yourselfer trying to remain “off the grid”, or just a concerned homeowner trying to save a dollar while helping to protect the environment at the same time, installing a residential solar power kit in your home is a worthwhile investment that over time will make you money through cheaper energy and a variety of tax breaks.
Using panels of photovoltaic cells, a voltage inverter, batteries and some wiring, you can not only save money with a residential solar power kit, you can also increase the value of your home significantly.

This is not a labor-intensive install requiring any expertise or mechanical know-how. Many home install kits are available on the market that walk you through integrating a solar power kit into your electrical system step by step.

Most kits and guides on the market promise to reduce your electricity bill by half, with a very real possibility of saving 100% of what you currently pay! This can sometimes be done frugally by spending less than $250 on materials.

In the United States, there are Federal tax credits of 30% of your project cost for most green energy improvements to your residence. This doesn’t even take into account the different state-run programs, such as New Jersey’s Clean Energy Program, that can also offset, or in some cases completely absorb, your costs. Many homeowners install systems that run well over ten thousand dollars and end up having their costs completely covered.

Another way to actually make money off of your residential solar power kit after it is installed in your home and producing energy is to sell renewable energy credits. Utility companies have quotas that they must meet for deriving power from renewable sources.

Brokers will buy these credits off of renewable energy producers like you and then sell them to the utility companies. Although not technically being paid for your energy, you are profiting from just generating this energy in an environment-friendly manner.

This can lead to thousands of dollars a year.

Net metering is the method by which you may feed electricity back into the grid. In this manner you may offset your power bill by 100%, although you cannot yet make money in this way.

The benefits of a residential solar power kit are nearly overwhelming, and with a bit of research and some initial capital, one can not only save a lot of money, but begin making some as well within just a few years.

Wind turbine blades are the key to a windmill’s optimal power output and the part of greatest diversity involved. Although the generator can vary widely based on the size of the installation, a single wind turbine design can be fixed with any number of different blades.

In the following, we are going to take a look at the different materials used in making wind turbine blades and their respective advantages and disadvantages.

A very popular option for homemade windmills is using wood to make wind turbine blades. Wood is obviously very readily available at any home supplies store or lumberyard, or if you’re feeling froggy, trees, whilst growing more elusive daily, are as yet usually possible to attain at your nearby forest.

Be it solid plank, laminate, veneer or a composite, wood is cheap, strong and lightweight, and a very legitimate material for this type of application.

Steel has been used in the past, but it is unnecessarily heavy and prohibitively expensive.

Aluminum, while it is light and easy to work with, which is crucial in a project like this; is also subject to metal fatigue, making it a less attractive choice.

Fiberglass is probably going to be the best choice for the average person that doesn’t want to use wood, and there are several different varieties out there. Cloth over frame, pultrusion, and filament winding to produce spars.

An easy and cheap way that a homemade set of wind turbine blades can be made is to just buy a length of PVC pipe and cut it into quarters. The quarters can then be cut down into a blade shape easily.

The enormous modern wind turbines being used more frequently around the world now will use much more advanced technologies for their blades, such as GFRP, glass fiber-reinforced  composites, and carbon fiber-reinforced composites. Various polymer matrix composite materials are being used in monolithic, or single skin, and sandwich composites.

Research is constantly underway to find a lighter composite with greater strength that does not sacrifice fatigue, and thus the composite genre will continue to evolve. Therefore, wind turbine blades will also continuously improve. But for the average user, the materials mentioned earlier will be encountered far more often, and provide an affordable, environmentally friendly avenue to energy.

Major problems associated to energy today are the ever increasing energy prices and non renewable energy sources which are going to end, sooner or later. Solar power kits for your home can be a solution for this problem. Power produced from solar energy is not only renewable but also environment friendly and is perfect for the future world’s energy needs.

Solar power kits for your home are environmentally friendly and are becoming more and more popular every day. There are a lot of good advantages of using solar power kits for your home. Here are a few of them:

Saves Money

Most of our power is generated from power plants that are fueled by fossil fuel which are speedily depleting. At the same time as supply is decreasing, demand is increasing. The law of supply and demand will drive the costs of electricity to elevated levels.

When you create electricity by going in for solar power kits for your home then you need not to pay for outrageous prices for electricity.

The initial costs of solar power kits for your home can be high but these expenses are just one-time and you should consider this as an investment– which they really are. Best part to opt solar kits for your home is that you probably never pay another electric bill again which is increasing day by day.

Solar power kits for your home will help you earn money if you are able to generate excess electrical power as the excess electricity can be sold to the local utility. So clearly solar power kits for your home is an approach on which you can even recover the initial expenses as well.

By opting on DIY Solar power kits for your home with small investment you can get immediate results and can also get the relief from high installation costs when done by professionals. But you need to have patience and dedication to build it.

Environmentally friendly

Solar power kits for your home are environmentally friendly as it does not create any harmful pollutants and emissions. As at present most of the energy comes from power plants which emits very harmful green house gases, which are resulting in the problems like Global warming, sea level rise, melting of glaciers, extinction of many animal and bird species and lot others. As we all are responsible for this, so go in for solar power kits for your home and balance your carbon footprint.

Renewable

The source of energy for solar power kits for your home is renewable. The sun is the main source of solar power so its resource is immense, is free of cost and is available everywhere.

Backup during Power failures

Solar power kits for your home can help keep lighting, air conditioners, internet connections, computers and many other household appliances running in power outages.

Set an Example

By implementing solar power kits for your home you can set an example, by raising awareness and educating your kids, family and the community around you.

If you are in the market for a home wind power kit, there are a few things that you should familiarize yourself with before investing. Not that the investment is a bad idea! Quite the opposite. But a bit of knowled
ge never hurt anybody. Except for Copernicus.

As far as a home wind power kit is concerned, it is a relatively long-term investment to generate renewable energy that depends fairly heavily on your local conditions. Wind speeds of at least 10 Mph are suggested, and if energy costs less than 10 cents/kWh where you live, you may not profit much any time soon from one.

Small turbines run from $5,000 to $20,000, create about as much noise as a washing machine, and take up enough space that you don’t really want one in the suburbs. If your local wind speeds are high enough, you will be covering your home energy costs by 50 to 90% and helping the environment to boot.

If you’re curious about what size home wind power kit would suit your residence, keep in mind that most homes use about 9,400 kilowatt-hours of electricity per year. Taking into account how much wind you can provide your home wind power kit, this means you would need a turbine in the range of 5 to 15 kW to provide power for your home.

And, oh! The environment will love you for your home wind power kit. Over its lifetime, your turbine will offset over a ton of air pollution and hundreds of tons of greenhouse gases.

Check the U.S.

Department of Energy to determine what sort of winds you are dealing with in your area. Contact the manufacturer of your desired home wind power kit to determine what utility company approvals you may need. Your install will involve a tower from 80-120ft tall to raise the turbine above wind obstacles on the ground, but no rewiring of your house will be necessary.

The utility company will usually install another meter to measure how much power you are generating at no expense to you; they have to connect and purchase power from such systems according to Federal regulations.

A home wind power kit will last over 20 years without any maintenance, and depending on wind, will sometimes pay itself off in as little as 6 years!
