The 9 Essential Items You Must Have In Your Solar Panel Assembly! is a post from: How to Build a Solar Panel

The steam can have a degrading effect on the interior paint work and fittings; it will age your vehicle prematurely and will leave unpleasant odors. Let alone the stale air you keep breathing in which is being re-circulated around your motor or the need for extracting the heat and cooling the air temperature.

When looking to install a ventilation fan into your RV, you need to consider these two points:

• What size fan do you need?

• How are you going to fit it?

Solar extractor products are measured in the amount of air it can extract per hour, so you are looking at cubic feet of air per hour. To calculate cubic feet, you multiply the height x width x length of the inside of your motor home together.

Then you need to work out how long it will take to replace the air. For example, if you had a product that can extract 500cb ft per hour. You would need to divide the cubic feet of your RV by 500 and then multiply by 60 to give you a figure in minutes.

You can get different size ventilators which have corresponding different size solar panels. For example a 12,000cb ft per hour vent would use a 100 watt panel.

Bear in mind that you can get extractor parts made from different materials, so if you live in a harsh climate or near the sea you might want to consider a stainless steel one.

The second point we now need to consider is how your are going to fit it. The most obvious place to site the electric fan is in the ceiling. However this is not as simple as it may seem. The disadvantages of solar fans is that to fit it in the roof you have to cut a hole in your roof which is about 120mm in diameter. Unless you are pretty handy at doing DIY then I would suggest you get a professional to do the work for you.

If you are going to do it yourself, I suggest you do it by marking out the diameter of the whole you need; then use a 10mm drill and drill a series of holes inside the diameter of the circle you have scribed. Drill these wholes close together and then use a hacksaw to finish off the job.

Alternatively what you can do is fit the fan to a piece of hardboard and position it in the window of your door. As you wind the window up, you trap the hardboard in the window frame.

Finally, you are left with attaching the RV solar panels, read the instructions carefully and make sure the system is in the best position for absorbing as much energy from the sunlight as possible. There is not much in the way of electrical systems to worry about, all you have to do is connect the solar powered panel to the unit, and that is all there is to using solar RV fans.

Before you start searching for the cheapest solar electric panels, systems and accessories such as an inverter, generator, battery or batteries (for off grid storage). You need to first calculate your energy requirements in watts. You can do this in a number of ways, you can go round and look at the wattage of all your appliances and add them up, or you can look at your electric meter and determine how many kilo watt hours you use per day on average and then multiply that figure by 10% to 25% just to give you a little to play with.

Once you know that figure then you can go and look for the cheapest products. You can get a 1.2 watt panel for $32, and you can get a 210 watt panel for $836, and there is a whole range of different sizes and prices in between.

However, when looking for the cheapest system you must remember that buying the products only accounts for half the cost. The other half of the cost is fitting the systems, paying contractors to install and wire them up to your home. If you do this job yourself, then you can make considerable savings or if not do it yourself then control the project. You might then want to spend a little more on getting more efficient panels and so generating more power for your buck.

Remember that you do not have to purchase and install all your panels at once. You can spread it over time, start small and inside your budget, and as you see the benefits in reduced energy bills and have new savings, then you can invest again and add another solar array or two. It is a fairly straight forward process of adding cells when you have the basic installation in place.

Build Your Own Homemade Solar Panel

Of course the ultimate way to save money is DIY. There are plenty of books around which will teach you how to make a solar panel and the pitfalls to look out for when building one. They do go into real detail so you can see exactly how to assemble the photovoltaic cell into an array and build a panel. They even explain where you can source the cheapest solar cells and find damaged ones which you can repair. Their efficiency won’t be as high as a factory made one though.

The down side here is that you’re exchanging time for money. If you have plenty of free time and are good with your hands then this could be a good option for you. This residential solar power system is sitting on your house and is exposed to all the elements, so it has to be made waterproof else they won’t last.

To summarize, the cheapest solar power systems are the ones you make yourself but they won’t be as efficient and you are exchanging time for money. Take your time and weigh up all the pros and cons.

Cheapest Solar Power Systems is a post from: How to Build a Solar Panel

When calculating how many solar panels you need for your home, you don’t need to be too concerned about the efficiency rating of your panel because photovoltaic solar panels are specified by their energy generating capacity. For example, 100 watt panels will output 100 watts of energy under ideal conditions. So if you are looking to produce 1kw per hr of energy you will need 10 x 100 watt panels.

Solar panels range in their energy output. Typically they range from 30 to 205 watts. If you are DIY then pay special interest in calculating your energy requirements. If you are getting a company to draw up plans for you then they will take care of this calculation.

There are three main types of solar photovoltaic cells and these are polycrystalline, monocrystalline and thin film. Each has different efficiency ratings when converting the suns energy into electricity and they all have their pro’s and con’s.

The main difference between them is size and price. The more efficient technologies like monocrystalline panels are more efficient than the other two and so the panels are smaller and take up less space when comparing like for like in energy output but they are more expensive.

So before you decide which panels to go for, you need to calculate your energy requirements, establish how much you want to invest and then go and compare the different panels.

There are many other aspects that can affect the efficiency of your panels. We find the following to be the most common: how often you clean them, are they infrared, how much sun do they get and how hot do they get. It is a surprise to many people that for most panels their efficiency drops when the temperature starts to go above 25 Deg Celsius.

Keep in mind, in this article we have been talking about photovoltaic electrical solar power generation. If you want a hot water heater conversion then solar thermal panels are a lot more efficient.

In summary, on face value solar energy does not seem very efficient, although it is improving year on year. However, don’t get too tied up about the efficiency of the panels, focus more on the output, size and level of investment.

If you have any efficiency figures of your own which you would like to share with us then please feel free to add them to this article by adding a comment below.

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 solar electric products 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”. I read about a couple of people who can build a 100 watt panel for about $200 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?

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 is 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 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! 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 materials you need to build a solar panel – cells, board, flexi-glass 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.

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.

Build a Solar Panel and Make Your Own Solar Power is a post from: How to Build a Solar Panel

If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid.

You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money!

The Solar Powered System

Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power.

The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power.

The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid.

Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid.

If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.

How Do You Hook Residential Solar Panels to the Grid? is a post from: How to Build a Solar Panel

Thin film solar panels are one method of generating electric power from the sun that’s only come onto the market in recent years.  They’re also called amorphous silicon photovoltaic cells, and they aren’t rigid, unlike traditional panels.  They use an amorphous type of silicon instead of one or more crystals.  These thin panels could end up replacing rigid monocrystalline and polycrystalline solar cell.  Made of a silicon material placed between flexible laminate, steel or glass, this new type of panel has some real possibilities.  Let’s take a look at the good and bad things about this new type of solar panel.

The most common and popular type of thin film solar panel is the flexible laminate type.  That’s because they’re the most versatile.  Their thin film allows them to be applied to almost all surfaces and to take up a lot less space than a traditional panel.  They’ve even been used as a type of roofing material.  Unlike rigid panel types, they don’t stand out, blending in better with the roof itself.  They can actually be used instead of steel or shingles for roofing, creating an entire roof that generates power from sunlight.

However, there’s a reason why thin film solar panels haven’t replaced older types yet.  They’re just not as efficient.  With about a six percent conversion rate for energy drawn from the sun, they can only draw about half the wattage from sunlight that mono and polycrystalline panels do, making them take up twice as much installation space for the same amount of power.  They do cost less, however. 

Their thinner structure needs less material, allowing much cheaper panels to be produced.  In terms of price per watt of power output, thin film panels are as high as other technologies, allowing budget conscious homeowners to pay less for their power generation.  At about seven to ten dollars per watt, the costs are lower than the other solar panels on the market.  The best known brand is probably UniSolar.

The less fragile nature of these panels also means they are unlikely to become damaged during shipping.  Monocrystalline panels, by comparison, are especially fragile.  For those who aren’t worried about space but are worried about what they’re paying for their solar power system, these are a great choice.  You should be aware that their longevity may be questionable, though.  There’s a possibility that they’ll hold up just as long as their competitors, but this technology is new and still hasn’t been well tested.  A decrease in efficiency may occur over time.

One benefit of thin film solar panels that other types can’t offer is that they don’t suffer a decrease in output when temperatures go up.  Some may even have a slight increase in their outputs.  That’s impressive, since areas where sunlight is readily available are also usually hot.  Because of this, thin film solar panels often have an actual output that’s very close to the one they’re rated for.  This can make planning a solar power system much easier using this kind of panel.

Monocrystalline solar panels are one the most efficient commercially viable photovoltaic solar collectors, but not necessarily the first choice for every home!

Monocrystalline photovoltaic electric solar energy panels have been the go-to choice for many years, and are among the oldest, most efficient, and most dependable of technologies.  If you’ve ever seen black or iridescent blue panels on a roof or powering a device, they were probably monocrystalline panels.  Each module is made from a single silicon crystal, and is more efficient, though more expensive, than the newer and cheaper polycrystalline types.

Here’s a look at the benefits of monocrystalline solar panels.

These are generally considered the workhorses of the solar power market, and most people will choose monocrystalline panels due to their ready availability.  These panels are easily identifiable, made up of uniformly stacked rounded cells.  Because they’re made from just one crystal, not multiple crystals fused together, the process of making them is one of the most complex and costly ones around.  That means every panel will cost more.

However, that increased cost is buying additional efficiency, meaning one panel will produce more power than lower priced options.  If space is a concern (which it often is with solar panels), monocrystalline will be the best type to use.  More wattage per square foot can be delivered with these panels.  The average 175 watt panel is about sixty-three inches in length, thirty one inches in width, a little over an inch high, and weighs thirty-three pounds, with an aluminum frame.  The lifespan of a monocrystalline cell is a minimum of twenty-five years and can be more than fifty, making them a worthwhile investment for long term use.  These panels are extremely fragile, however.  That means a rigid mounting is a must.

Like other types of solar panels, monocrystalline solar modules suffer a reduction in output once the temperature from the sunlight reaches around fifty degrees Celsius/a hundred and fifteen degrees Fahrenheit.  Reductions of between twelve and fifteen percent can be expected.  These are lower than the reductions in output experienced by polycrystalline cells, but they still need to be factored into the calculations and design for any solar power system.

For those putting together a long term solar setup who want to know they have access to the best and most reliable panels on the market, monocrystalline types are probably the best bet.  They’re costlier than polycrystalline options, but their longevity, performance, and efficiency mean that they’re a good buy over a longer period of time.  When you want to be sure you’re producing the highest wattage per square foot, these are the modules to rely on.
