Can You Make Your Own Solar Panels?

!±8± Can You Make Your Own Solar Panels?

Reducing those bills coming through your letter box is something that everybody wants to do. If you can couple this with being green then great. Solar Panels are a top way of doing both. But, should you make your own?

Generating and supplying energy to a wide variety of residential and commercial applications, they are becoming home and business must-haves. And, as with anything, many people have tried their hand at making their own.

With technology improving on an almost daily basis, the big and bulky solar panels of the past have long been improved - leading to price drops and bulk manufacturing. Here is a five simple step list to help you on your way to building your own solar panels:

The Panel - As we all know, the solar panel is where the energy from the sun is collected and channelled.

Charge Controller - The fitting of a charge controller allows the regulation of energy flow. By helping to stop the overcharging of batteries they will have a longer life..

Battery Storage - With the energy being stored in a deep cycle battery, it is advised to keep a battery charged around 80% to ensure longer life.

Power Inverter - The electricity will be stored as a Direct Current (DC), and to get it to be used for household appliances it needs to be converted by a power inverter to Alternating Current (AC).

Start it up - After the purchasing of these four pieces, and they have been built, your household can soon be power by the sun's energy. The thing about solar panels is that regardless of how small (or large) you build one, there will always be scope for adding new panels as and when you want to.

Once the solar panels are set up you soon understand how much money is saved by them. It is generally suggested to have a professional company set it up so you can be guided into creating the perfect system for your needs.

Going green is a commitment, and one that needs to be stuck to. Generally, it will be advised to make photovoltaic solar panels if you are going to have solar energy but with homemade devices you can usually only use passive solar energy. The main issue is that materials are not as simple as they look to manufacture and are very specific, needing to be produced in the right conditions.

Charge a Battery with Solar Power and augment Electricity into the Grid

Once your battery is fully charged, very little current is needed to keep it topped up. Most of the available power from your solar panels is wasted as the charge controller is mostly switched off. Enter the 12 volt grid tie inverter which can export all that solar power to your mains electricity grid, saving you money. But how do you keep your battery topped up and send surplus power to the grid at the same time? The PWM5 Solar Charge Controler from www.256.co.uk is the only charge controller with 12 volt grid tie inverter compatibility built-in. Make your solar panels really work for you.

Solar Tutorial - Amps & Volts

!±8± Solar Tutorial - Amps & Volts

Solar panels differ in the amount of volts - the force of the power - and their amps - the flow of charge - that comes from them. Two 10 watt panels may differ by several volts & some amount of amps. This affects how they will charge your battery system.

We're going to keep this simple. There aren't many things worse than math.

When it comes to solar panels, there are watts, amps & volts.
Watts are a measure of the power of a solar panel.
Amps is also referred to as 'current', and is a measure of charging rate.
Volts is also referred to as 'electric potential', and is a measure of the force behind the flow of charge.

Watts is Amps multiplied by Volts (if you remember your high school physics). So a 10 Watt panel is twice as powerful as a 5 Watt panel.

Now to complicate things a bit, you should know that different solar cell chemistry will produce slightly different voltages. For example, a 10 Watt solar panel using the CIGS cell technology (like the panels from Brunton) operate at 16.5V, whereas the PowerFilm amorphous cells create panels that have an open-circuit voltage of 15.6V.

Which is better?

Well, remembering that Watts is Amps multiplied by Volts, it stands to reason that a 10 Watt panel that provides more Amps, will be the solar panel that will charge a battery pack the fastest.

Most solar panels are designed for use in what is termed "12 Volt systems", even though "12V" is not actually an accurate term. 12 Volts is used because this is the nominal voltage of a car battery, and is an easy multiple of 120V AC power that you find in your home. A lead-acid battery like the one in your car, contains 6 cells operating at 2 Volts each. A 12V battery is actually just over 13V when it is completely full, and somewhere around 10.5V when effectively empty.

Lithium batteries have followed this convention as they were the latecomer to the scene.

Charging batteries is somewhat like siphoning water from one bucket to another. As long as the charger has a higher voltage than the battery it is charging, charge will flow between them, and the battery will get charged. This is why solar panels are designed to be 15-18V, in order to properly charge a 12V battery. Charge controllers are used to make sure that the panels do not overcharge the batteries once they are full (in the siphoning example, this would be like closing a valve on the hose once the second bucket is full).

Since lithium batteries are everywhere in small electronics, the personal solar chargers are designed around them. This is why the USB format has become the standard for charging small electronics - the 3.7V lithium cell charges from the 5V USB. Lithium batteries in small electronics also comes with their own built-in controller that stops them from being charged once they are full.

Wind generator charge controller

!±8± Wind generator charge controller

One of the most important things you can get for your wind turbine is, the charge controller. As the name suggests, this device is used to control battery charging. Continuous overload your cells can cause electrolyte boiling, so that the batteries dry, and ultimately ruin the expensive battery bank.

If you are familiar with how other people work charge controllers, such as solar cells, for example. You should know that simply monitorBattery voltage and when the batteries are fully charged, the control panels of the shorts. However, this type of device does not work for wind turbines because they could burn the controller, or even destroy your generator.

You might think, why not disconnect the batteries when fully charged? Well, this does not work, because most of the wind turbines is overloaded if they are not loaded, and then possibly further damage to the generator. This happened to a friendI recently, and was not amused by this at all.

So this makes the installation of a wind turbine load controller as the only plausible option. This means that the batteries are fully charged and then automatically to an alternating load, which may continue to change the power generated by the wind to be used elsewhere.

Some of the things that you can use the extra energy by heating water, powering your home refrigerator or just using it for lighting the house. WindAlternator charge controllers are on different voltages such as 12V, 24V, 36V and for each model available to meet wind turbine.

How Solar Power Your House - Tips for creating and installing a solar power system at home

!±8± How Solar Power Your House - Tips for creating and installing a solar power system at home

Would you like to have your electricity from a clean source of energy? Are you worried about rising costs for electricity, based on our country's dependence on limited resources? If yes, then you might be interested to know how solar power your home. Unfortunately, solar systems can be very expensive.

The good news is that you learn to build itself to zero! It does not cost much money, if the parts on eBay or your local shop.All you need is a good guide that explains everything you do in a simple way.

Before you begin, here are some things you know about solar energy systems.
They have some solar panels for the project. You can build these from scratch or buy it. You can do very heavy, fortunately so they are available at an affordable price. You will find solar panels on eBay or Craigslist to sell. The cell is only one component of a system of solar panels, you can stillbuild the rest from scratch. You also need a regulator, inverter and battery charging. The charge controller prevents overcharging and convert the inverter 12 volts direct current into 120 volts alternating current, which will be needed for your home. Extra energy is stored in batteries, so you have electricity at night and on cloudy days. How to build the system, you must cover the solar panels with cardboard to prevent them being enabled before you're done. TheirYou may need a permit to install the system once it is finished. Check with your local zoning department to find out what you need permission to install your solar panels. You could try, that your roof will be able to withstand the plates and that all cables are secure. Learn the difference between "grid connected" and "off the grid". Grid-tie means that it is still connected to the utility company. Off the grid means that you are 100% self-sufficient. It can be very liberating experiencelive from the network, but you may need to make sacrifices to get there. On exit, you should leave the solar system on the network still on the hook and some power companies. You never know when something might happen that cause cell damage. You will receive an electric bill per month, but the costs are much lower than what you pay today. There are several types of installation: mounted on the floor, ceiling mounted, installed static, active solar tracker andpassive solar tracker. Solar trackers are more efficient, but can be very expensive. Most residential solar panel owners to choose the static method installed. This includes the configuration of solar collectors, where you get the most sunlight, think, and hope for the best. Chances are, this place will be on the roof, even if you need to drill some holes in your roof for installation.

Solar charge controller for solar panels

!±8± Solar charge controller for solar panels

The photovoltaic modules are the choice of consumers.

With the price of fossil fuels on the rise, companies have the power of fuels such as coal and oil to leave in order to generate most of their electricity had been forced to raise prices, then the homeowners are now opting for ' solar energy to meet their energy needs. Photovoltaic systems are very popular with home owners and apartment, because the energy is free, and recent technological advances have reduced the initial cost of suchSystems.

The batteries require constant charging.

Because of the intermittent nature of solar energy, is not useful devices directly to a photovoltaic panel. Instead, power is through the plates during the hours of sun-charged batteries, where it is stored for use on record upon request. The output of solar panels depends on certain factors such as the position of the solar cells, the time of day and season. All these factors affect the incidence ofSunlight, photovoltaic cells and thus the temperature of the cells. Because these dynamic conditions, variations in the performance of the plates are not conducive to a battery of good health. As a general rule, such as batteries, at a rate that is approximately 20% of their amp hour rating for free. For example, an amplifier 10 would be ideal to calculate a 50 amps hours of battery life. Because the batteries can not fast overload, is a solar charge controller requiredTo ensure the correct charging current is maintained.

What is a solar charge controller and how it works?

A solar charge controller is an electronic circuit, the output voltage and current from solar panels on the needs of the game fits batteries recharged. To charge a battery, charger - or in this case, the solar system - must be uploaded to a potential higher than the battery. In other words, the voltage must be greater than the plateopposite the battery voltage under load to produce a positive flow of current in the battery. But how much more should it be? The current flow is based on Ohm's law: E = I * R, where E is the voltage in volts, I is current in amperes and R is the resistance in ohms is measured. The effective voltage in this circuit, the output voltage of the solar battery voltage less the opposite. We can make a difference in voltagenecessary, our current flow desired by inserting our values ​​lead to the known equation. Assuming a 12 volt battery with 50 Ah capacity, charge current, our goal is to be valued at about 10 amps. There is no resistance in this circuit, with the exception of the internal battery resistance, which is a fraction of the ohms. In this case, we will approach was 0.2 ohms. With Ohm's Law, we multiply 10 amps of 0.2 ohms and get 2 volts as a result. This means that our solar panel must be 2 voltshigher than our battery voltage to obtain our goal to hold a charge. This example shows that the nominal output voltage of the solar panels must be greater than the battery charge controller for solar pay for the job. As mentioned, the current values ​​dynamically, and thus the need for a charge. There are some very sophisticated solar charge controller available today, use the Maximum Power Point Tracking MPPT, or in order to adapt to differentCombinations of battery and the panel as 24V, 36V, 48V, etc. These controllers use DC-DC converter to match the voltage and measure the use of digital circuits for the current parameters many times per second to adjust the power output accordingly.

The charge controller is necessary to correct.

As you can see, is a solar charge controller is an essential part of any PV system. It 'true that a simple charging circuit function can be achieved with fewer parts to buildto save from your local electronics, this option is not recommended for the average person. With so many variables associated with solar energy, is to use a solar charge controller, the ability to monitor all relevant parameters and recommended the optimum cost for the batteries, however. Using a high-quality solar charge controller ensures that you enjoy maximum battery life and the best of your PV system.

Solar Panel Charge Controller - store batteries Lives'!

!±8± Solar Panel Charge Controller - store batteries Lives'!

During this period, when prices climbed to almost everything, while the increase in income does not seem to find more and more people are looking for ways to cut costs. One category that affects people's wallets is particularly difficult for energy costs. Solar panels are becoming increasingly popular, as the technique is perfected and people find comfort in a reliable way to effectively reduce or eliminate monthly electricity bill. There are two different categories ofSolar systems - those that supply energy to local electricity grid and those that use batteries to store solar energy captured. For those who have solar cells with batteries, there is a small inconvenience that has a simple solution: a solar charge controller module.

The specific problem is that the batteries are designed with so much energy into one. If you are constantly bombarded with the battery trusted too much energy, cease to be so true. Batteriesare expensive, so obviously you want as long as they were designed. To save battery life, you need to buy a solar panel, charge controller. He has only one function, and this is to prevent the solar panels from overcharging the batteries.

The first model of the solar panel charge controller is nothing like it is today. In his introduction, was literally a mechanism to separate the plates from the batteries. Today the technology is veryis more advanced. The key to buying the right to be attentive to the tension. What are the volt batteries must correspond to the charge controller. If you have already received a charge controller and realized you have the wrong voltage, do not panic. Made most controllers these days have to adapt, but if you have not purchased a charge controllers, to make things easy on himself from the tension.

The share of solar panels with batteries instead of the ownerare on the web less and less. Many want to take advantage of tax breaks, rebates and other incentives on the network. If this is not an option for you or you prefer to use batteries that prevent many unnecessary headaches and a charge batteries using the solar panel. You will end up saving money, stress and hassle, if the battery before it fails.
