The problem for many people who want to reduce their carbon footprint and reduce their energy bills by using solar power, is the cost of installing a system in their home as it can be frighteningly expensive. Most systems seem to start at around $8000 for an average house, although this does include all the materials and fittings. Which is fine if you can afford it, but if you can’t? What are your options – DIY or build a solar panel?

One of the cheapest options is to buy the photovoltaic solar panels and fit them yourself or an even cheaper option is to “build a solar panel” yourself. I read about a couple of people who can build a 100 watt panel for about $100 and at this cost it fits into most people’s budgets. However, solar panels can seem a little complicated and where on earth do you start to go about building one?

The second problem is knowing what size and how many solar panels you need to power your home or RV and all the things that go in it like; washing machine, fridge freezer, microwave oven, heating, ceiling fans, lighting, TV, computer, music system, etc.

I am not the most technical of people and anything to do with converting sunlight into electricity and electrical circuits, normally goes straight over the top of my head.

However, I had the good luck of reading about Michael Harvey who is a self proclaimed renewable energy enthusiast. He builds his own solar panels and got so good at it that he wanted to share his knowledge with the rest of us. Therefore, he wrote a book called Earth 4 Energy. It is a step by step guide to building your own solar powered electrical system for running electrical appliances inside your home. I have to say I am often disappointed with DIY books because for some reason they never get to show you, in detail, how to do the tricky bits.

However, with this book you can see exactly how to do it. The bit that concerned me the most about building my own solar panel was assembling and wiring the solar cells together because if you get this bit wrong then everything else is a complete waste of time. Well, I was so impressed with the two videos that came with this eBook. You can see exactly how to assemble and solder the cells together, and in fact it is really simple, you don’t need any special skills and is simpler than assembling a flat packed bookshelf! Plus it explains how you can simply calculate how many solar panels you need to power all the appliances in your home, including heating and lighting. This is the main reason why I feel very happy to recommend it to my readers.

What this book gives you is:

* A step by step plan on how to build a solar panel.
* Advice on where to get solar cells to make your solar panels at greatly reduced prices.
* A complete list of products you need to build a solar panel – cells, board, flexi-glass sheet, etc.
* A complete list of tools you need to build a solar panel – volt meter, soldering iron, copper wiring, etc.
* Two videos showing you exactly how to wire the solar cells together to make the solar panel – which are excellent!
* Advice on how to charge a battery and live “off grid” or connect to your home’s electrical wiring system via the AC breaker panel.
* Tips on how to maintain your solar panels.
* Excellent support with a 12 hour response time for emails.

It also gives you a full glossary explaining all the different technical terms like what an amp is, how an agitated electron produces electricity. It also explains about the difference between using solar energy to heat water and using it to produce electricity and when you to apply each one to meet your household needs.

If you want to save money and learn how to build your own electric solar panels to generate electricity for your home then this book is a must read. It has to be one of the cheapest ways to generate electricity.

How To Build a Solar Panel For Less Than $100 is a post from: How to Build a Solar Panel

Have a look here if you want to learn how to build a solar panel.

Because there are no moving parts, and therefore no risk of mechanical failure, most solar electrical systems will continue to supply power for 30 years or more. Though some smaller solar electrical systems can be comparatively straightforward to install, many folks opt to hire installers. They are often made from silicon crystal slices called cells, glass, a polymer backing, and aluminum framing. Sometimes the “size” of a PHOTOVOLTAIC module refers back to the panel’s rated output wattage or electricity generating potential. Those with  twelve or twenty-four Volts are usually preferred for off-grid systems with battery banks. Other solar panels come in less common nominal voltages like eighteen, 42, and even sixty Volts.

These modules are sometimes utilized in grid-tied applications to deal with the working of grid-tied inverters. Solar panels can be employed alone or combined into arrays by wiring them in or in to reach the required. The cost of most large home or commercial PHOTOVOLTAIC modules can range between $4.00 and $5.40 per rated watt. In PHOTOVOLTAIC system language, everything besides the PHOTOVOLTAIC modules themselves is named balance of system. Solar panel mounting systems include hardware to permanently affix the array to a roof, a pole, or the ground. These systems are usually made from aluminum and are selected based primarily on the categorical model and number of modules in the array as well as the specified physical configuration.

A solar array on a tracker will produce more energy than a fixed array. Trackers are typically utilized in water pumping applications.

The price of a tracker can be serious, and because of the possibility of breakdown, they are best suggested to the mechanically inclined. The price of a mounting system varies based totally on the number of modules and sort of mount. The average cost is between $250 and $1,000 for a fixed array and $2,000 and up for a solar tracker. The combiner box is an electric enclosure which permits multiple solar panels to be mixed in parallel. For instance, if you’d like to wire together 2 twelve Volt panels for your twelve Volt system, you will wire each panel’s output to terminals within the combiner box. From the combiner box you can then run only 1 positive and one negative wire to the next system part, the charge controller. The combiner box will also house series string fuses or circuit breakers. These boxes are sometimes outdoor-rated, and intended for placement right next to the array or solar panels. A charge controller manages the quantity of current the PHOTOVOLTAIC modules feed into a battery bank.

Their main function is to stop overcharging of the batteries, but charge controllers also block battery bank current from leaking into the photovoltaic array at night or on cloudy days, draining the battery bank.

The 2 main types are Pulse Width Modulated and MPPT (Tracking). The controller must moreover have enough capacity (in rated Amps) to deal with the total current of the solar array safely. MPPT charge controllers can track the maximum power point of a solar array and deliver 10-25% more power than a PULSE WIDTH MODULATED controller could do for a similar array.

They do this by changing excess voltage into serviceable current. Another feature of MPPT charge controllers is their power to accept higher voltage from the solar array for output to a lower voltage battery bank.

Nobody likes to take cold showers.  Dishwashers are impossible to operate without heat.  Water heaters come in many styles and sizes.  The majority of the heaters run on fossil fuels.  If you live in any climate, do you realize you could actually build a solar hot water system for your home or office? You will want to make sure it’s done properly, and to save a little on labor and supplies, you can in reality build your own system.

One source is solarfriend.co.uk, the site goes into good detail about what is needed to install your own system.  The author of the website claims their household has the potential of spending only £300 annually on electricity using the solar hot water system they installed.  This site will give you great detail, with step-by-step photographs, on how to build your own flat plate or evacuated tube solar collectors, panels and pipes.  The author explains the difference between the two systems, while providing diagrams as visual aids. There is also mention of a freeze-proof roof mounted water panel.

The El Paso Solar Energy Association (epsea.org) has many tips on alternative energies, including using the suns energy for passive solar water heating.  Passive solar heating is the oldest form of commercial solar energy. Terms you might find familiar include PSWH, Batch heater and Bread Box – and these are the passive solar water heaters.  General descriptions are given for these systems on this site, as well as general information on how to build your own.  For instance, you can paint your water heaters a flat black to retain more heat for longer periods of time.  Small diagram drawings are provided to show you some of the final products that you can build alongside verbal instructions on the build.

Several different types of solar water heaters are covered on jc-solarhomes.com.  Whether you are interested in passive or active energy.   Diagrams are given to the readers for assistance in building their own solar hot water systems.    Minimal verbiage is provided to the public. The site does offer a lot of FAQs that should be able to answer most consumers’ questions about cost, how solar power works, and how the systems work.  Flow rate theory and flow dynamics are given their fair share of educational points.  This site gets into some of the nitty-gritty that engineers may be interested in knowing.  If you are to purchase the E-book that is available at the site, you will be given step-by-step instructions and a total list of supplies needed to build your own system.

Popular Mechanics has an article on their website regarding the "Energy Family" making their own solar water heater.  This family has piggybacked their solar system on with a propane system.  They are trying their best to retain a small carbon footprint.  There is a four-step method covered with matching photographs as the family put together their system.   Supplies are listed so that you know what you need to purchase to get started.  Some general information regarding savings and costs involved are also given to the reader.  A very informative comment section can be seen at the end of the article, allowing you to learn even more about the solar hot water systems.

The best recommendation that can be offered would be the first site.  It is the most informative of the bunch, and has photographs, diagrams, and verbal instructions so that most anyone can follow and be able to manufacture their own solar hot water system with a minimal amount of problems.  Ideas are complemented with suggested buys for the parts needed so that you can start your savings right away.

How to Build a Solar Hot Water System Review is a post from: How to Build a Solar Panel

Solar collecters are fairly simple devices, and if you would like to make your own solar collecter battery then we have given you a few pointers in this article.

You can do it yourself; as long as you have the patience to learn, that is.  Harvesting the sun’s solar power is one of the easiest things you can do to create energy.  With a few simple tools, you can build your own solar energy collector system.  This article will focus on how to make a solar collecter battery; however, this won’t work as a practical solution for powering your home appliances or hot water heaters, maybe you can use it to recharge a battery. Click on this link if you want more info on how to build a solar panel to power your home.

There are many forms of solar collecters, but for convenience’s sake, let’s just focus on a popular concept; the solar cell (or photovoltaic cell).  It is the most widely used solar collecter these days, but somehow, these little things tend to be very expensive.  The concept is simple enough, but then, the cost isn’t.  Therefore, making your own homemade solar cell (or in this case, solar collecter battery), is a viable option.

The Things you’ll Need

To start, you are going to need some copper flashing (or copper sheeting), tin snips, an empty 2 litre plastic bottle, steel wool, some table salt (which you put in a glass of tap water), a micro ammeter (whether a digital one or an old school one, it doesn’t matter), alligator clips and an electric stove (or a propane torch, whichever suits your fancy).

The Procedure

Now, it is time to assemble your very own solar collecter.  First, you are going to need to measure the copper sheets (or copper flashing).  Then you need to cut them with the tin snips.  Make the sheets small enough to perfectly fit on top of the heating coils on your electric stove.  Heat the copper until it looks bright red hot.  Let the copper cook for around maybe 30 minutes or so and see what happens.  You’ll see that you have made 2 kinds of oxides; the black cupric oxide and the other cupric oxide underneath the black one.  You don’t need the black cupric oxide, and when you see this forming all over, you’ll need to turn off the stove so you can let the copper cool down.  After that, you will need to use the steel wool so you can clean off the cupric oxide that you don’t need.

Next, cut out another piece of copper about the same size as your first one.  Place this one into the plastic bottle or tank.  Then, place the heated piece of copper in there too.  Link your alligator clips to your micro ammeter and then connect the negative part of the alligator to the cooked copper, while the positive one goes to the clean copper.  Pour some salt water into the bottle and then you’re done.  Place your makeshift solar collecter under the sun and watch your micro ammeter rise about fifty micro-amps.  Then, Presto!  You have now learned how to make a solar collecter device (or solar cell batteries) on your own.

These are just the basics, and while some solar collectors or photovoltaic cells are much more complicated, at least you now have a basic understanding of how to make a solar collecter system of your own.

How many solar cells are required to run my house? The answer to this question is not a simple one. There are a variety of factors that come into play in order for you to calculate the answer. Additionally, there are a number of variables that can make the answer change over time.

The number of solar panels (photovoltaic cells) you need to install to power your home will depend upon your electric power demands, the weather in your area, the angle of your roof, shade issues from nearby trees or buildings and the size of the cells. All of these factors are important and must be built into your calculations so that you can create the best solution for your home and your future needs.

Calculating Energy Usage

One of the hardest factors to determine is your energy usage. This will vary every day. The problem is from day to day, the amount of energy you use is not going to remain consistent; however, you should be able to calculate an average of your energy usage. It is always better to over estimate rather than underestimate.

A good rule of thumb is to first calculate your average daily usage and then multiply that number by .25. This will give you the number and size of solar panels you need in kilowatt-hours. Your electric meter provides you with a very straightforward way of knowing how much energy you are using each day.  Your meter should have either an odometer style readout or a dial type readout.  Your electric company should be able to provide you with instructions on how to read your meter if you are unfamiliar with it.  All you will need to do is record the meter reading and then 24 hours later record the reading again.  This will tell you the kilowatt hours you have used.  You might want to do several readings and average the results you get over a couple of days. If you have kept your energy bills for a couple of years, you can look at these and cross reference your daily usage calculations with your yearly usage.

The average home will use 25 kWh per day, but your usage may vary. You have to consider changes such as additional appliances or changes to your home that will use more energy. Another option is taking the highest usage you have ever had in one day and adding 10% to give you the amount of daily energy you need. You can then source the solar panels (photovoltaic systems) to match that.

Sun Availability

Another variable you have to consider is the amount of sun available. You will need to work out the average number of sunny days, shade issues, and your roof’s angel. All of these factors will let you workout how much sun is available for you to harness and convert in to energy.

The amount of sun required to produce a kilowatt-hour of electricity varies greatly from location to location.  This is due to the variances in the heat of the sun on different areas of the earth.  Many factors will influence how much sun is required to produce a kilowatt-hour of electricity.  The length of the sunlight during the day, the angle at which the sun is shining and the time of year can all affect the energy produced by the sun.  You will have to find out locally how much sun is required to produce a kilowatt-hour of electricity.

Once you determine the average amount, you can compare that to your needs. You can then plan on what to do with any excess electricity you produce.

How much stored energy you need is dependent upon how much energy you are using verses how much energy you are getting. It is always wise to have some type of storage unit so that any unused energy is not wasted but saved for future use. You can store electricity in deep cycle batteries or but a better system, assuming you are not off grid, would be to feed it back into the utility grid.

When feeding electricity to the grid, what you are actually doing is reversing your electric meter and so the electric company can end up owing you money. The important thing here is that it is a lot easier to feed electricity to the grid than it is trying to store it in batteries.

Choosing Solar Cells

Once you have completed your calculations you will need to find the right solar panel. Different solar panels output varying watts and amps. You might want to consider more expensive panels, since they are more durable and efficient which will allow you to use fewer panels overall.

When you are looking at solar panels you will find they are all labelled to tell you how many watts they produce.  One of the larger panels is a 120W.  If you were to get a 120W panel you would need to divide your kilowatt-hour usage per day by the average number of daylight hours per day for your area.  Take that answer and divide it by 120 to get the number of panels you need.

If you are building your own solar panel, you will need 80 about cells to make a 100 watt panel.

You should talk with a professional or a knowledgeable salesperson to help you figure your needs accurately and to help you ensure you get what you need. It is very important that you know the answer to how many solar cells are required to run your house, so that you are sure to get the correct number and type solar panel to meet your needs.

If you have a solar water heating system, it would make sense to have a solar water pump. These are typically circulating pumps and have their own in built solar panel which means you do not need a battery. A circulating solar water pump has a lift of about 650 feet and can fit into very small areas, down to 4 inches square.
