Virtually any solar power system that uses batteries needs a solar charge controller. The solar charge controller functions to control the power as it moves from the solar panels to the batteries. A proper charge controller will prevent the batteries from being overcharged. You can read solar power battery if you need to learn more about solar power batteries.

The simplest type of charge controller functions to monitor the battery voltage and opens the circuit to stop the charging process when the battery is fully recharged. Previously, charge controllers often had mechanical relays to open and close the circuit.

Eventually, pulse width modulation (PWM) became the norm for the charge controlling mechanism. This is a technique by which the amount of power supplied to a battery is reduced gradually as the battery reaches maximum charge. In addition to decreasing the stress on the batteries caused by the charging process, PWM ensures that they’re more fully charged, making them more efficient from the user’s perspective. It’s also possible to use a PWM charge controller to keep batteries “floating,” or in a completely charged state, for as long as you like. PWM also has the extra advantage of not having any breakable mechanical connections.

Maximum power point tracking, or MPPT, is the most recent evolution in solar charge controller technology. MPPT controllers convert excess voltage into amperage. This feature has a couple of major benefits.

The majority of solar power systems make use of 12 volt batteries, not unlike the ones found in cars, but these features work regardless of voltage. Solar panels usually provide much more voltage than the batteries require. Converting the excess voltage into amps reduces the time it takes to charge the battery, while the charge voltage stays at an optimal level. A solar power system with this kind of charge controller will provide power more efficiently.

Power loss is also largely eliminated with MPPT charge controllers. As low-voltage electricity moves along wires, it can experience high levels of loss, dragging down the efficiency of the system. A PWM charge controller used in a system with 12v batteries, for example, would use electricity of around 18v. An MPPT controller will use the highest voltage of any type of charge controller currently available. MPPT controllers experience less power loss because of this improvement.

MPPT charge controllers cost a bit more, but they represent a significant improvement. For this reason, they’re highly recommended. Finally, it’s also possible to prevent reverse-current flow with some modern charge controllers. During the periods when solar panels have stopped generating electricity, such as in overcast conditions, electricity can sometimes begin to flow away from the batteries to the solar panels. This sort of power loss can also make a serious dent in the overall efficiency of a solar power system. At these times, a charge controller will open the circuit, preventing any power from being transferred back to the solar panels.

Rising oil prices and the increasing tolls of pollution are motivating a significant number of people to switch to solar battery chargers. Go to 12 volt solar charger for more in solar interesting info about solar chargers.

Many people know that solar chargers are a good alternative to non-renewable sources of energy, but not everyone has found out how simple they are to build. The purpose of this article is to explain important information about different types of solar battery chargers, including how to put together your own.

Generally speaking, a battery charger is a power supply that sends electricity of a certain voltage to a battery. The battery is connected to the charger, and disconnected after it’s fully charged. If you want to charge a 12 volt battery, you can plug it into a 15-18 volt power supply. However, this type of system poses the risk of overcharging.

When overcharged, a battery’s life is likely to decrease. A badly overcharged 12 volt battery may even lose its ability to hold a charge. Fortunately, you can use a charge controller to ensure that the correct voltage is used to charge the battery and that the battery isn’t overcharged. If you’re using a 12 volt solar charger, you’ll probably want to be able to leave it connected throughout the day while the sun is shining, and thus a charge controller is a necessity.

For 12 volt batteries, the most common type of charge controller is the Pulse Width Modulation (PWM) type. In simple terms, this type of charge controller functions by turning a switch on and off rapidly. Initially, the switch stays “on” more. The switch gradually spends less time in an activated state as power is transferred to the battery, and when it’s fully charged, the switch remains off. In this kind of charge controller, a microprocessor chip usually handles the task of monitoring and controlling the charging process. There is no risk of overcharging with a PWM charge controller, even if you leave it connected to a battery indefinitely. Topping up a battery in this way is called “trickle charging,” and it will allow you to make sure that a battery is completely charged for whenever you happen to need it. If you’re using a 12 volt solar charger, it’s useful to have a feature like this. 12 volt batteries for boats and RVs are often charged in this way, for example.

A 12 volt solar charger is no more complicated than that. The source of the electricity is the only thing that differentiates a 12 volt solar charger from a standard 12 volt battery charger. As one would expect, a solar panel is the source of the power for a solar battery charger. If you want to save money, building a DIY solar panel to use in a 12 volt solar charger is a great way to go. To learn more, take a look at DIY Solar Panel.

Usually, solar panels used on houses contain 1/2 volt and 3-4 amp solar cells. If you’re using these types of cells, you’ll need to connect many of them to generate the 15-18 volts needed to charge a 12 volt battery. Currently, there are small solar panels of numerous different voltages on the market. Matching the voltage of the solar panel to your charge controller will allow you to create a working solar battery charger. On each charge controller, you’ll see a voltage rating, which tells you the correct voltage. A solar panel of 15-18 volts is usually a fairly safe bet if you’re unable to use a charge controller for whatever reason. If you are using a charge controller, the required voltage is precisely that – required. One great guide to building your own 12 volt solar charger is GreenDIYEnergy.

The method for wiring the solar panel to the charge controller depends on certain factors within the controller. Identify the type of connector used on your charge controller, and solder one onto the solar panel. If you can’t use a charge controller, you can use the same type of connector that’s on the battery. With respect to clamps, the spring loaded type are a good choice for larger 12 volt batteries. Even if you’ve never done soldering before, this procedure would actually be a good place to start, as it’s a very easy one. A soldering iron and solder, which you can find at places like Radio Shack, are all you’ll need to do this. Just twist the wires together, use the soldering iron on the wires, and touch the solder to the wires until it melts. As long as you’re careful not to burn yourself, and remember to heat the wires and not the solder itself with the soldering iron, it’ll be a simple process. Another great guide to building a DIY 12 volt solar charger is Homemade Energy. For more information, visit Homemade Energy Review.

It’s really that simple! Building a 12 volt solar charger is fairly simple as well. First, you’ll have to get a 12 volt battery. Making sure to get one with the appropriate voltage, you’ll also need a charge controller. Next, you’ll require a solar panel that also outputs the appropriate voltage for the charge controller – you can build one yourself or buy one. Then, just connect the solar panel to the charge controller, then connect the charge controller to the battery as outlined. Once you’ve done this, you’ll have permanent, free power! By using solar energy instead of oil to charge your battery, you’re helping cut pollution and dependence on foreign oil, and saving yourself a lot of money in the long run.

A long as your home has adequate roof space and the correct orientation to the sun, a solar power system could provide all of the electricity for your home. Because of a problem with one or the other of these requirements, many homeowners who would otherwise be interested in solar power have not been able to take advantage of the technology. This meant that the solar panels may not have generated enough electricity to justify the cost of installation. Improvements in solar panel technology in recent years should give hope to these homeowners, as modern panels are more efficient than older versions and are also more tolerant of sunlight that is hitting them at a steeper angle. If you take the solar panel and connect it to a 12 volt battery and charge controller, you have the most common application of a 12v solar charger.

The improved technology and more advanced manufacturing techniques used today provide better panels for all types of solar power installations. The solar cells used in these solar panels have improved in several ways and offer consumers better power generation than solar cells available even a few years ago. Being able to generate more electricity from less sunlight is the biggest advantage of these newer solar cells. This means that they can be effective at producing electricity for longer periods of the day.Because of this, they can be used to produce electricity for more hours per day. Older panels had a limited range of operation during the day and needed the sun to hit them directly. When the sun was hitting the panel at a steeper angle, these panels would generate little to no power, like in the early morning or late afternoon. They were also intermittent on cloudy or rainy days since even though the sun was shining, it may not have been bright enough for the panels to produce power. The newer panels will generate more electricity for a solar power system in all levels of sunlight and this can help many homeowners to justify a solar power system for their homes. They can also allow people with homes that have less than perfect alignment with the sun to justify a solar installation because of the additional energy they will generate.

These modern panels will also mean fewer solar panels for the average homeowner to provide 100% of the power for their house. Because there are fewer panels used, this will also mean the system is less expensive. For people with limited roof space, this can make a significant difference. To figure out how many solar panels you will need for your house, check out this Solar Panel Calculator.

One last advantage that these newer solar panels provide is their longevity. Ten to fifteen years was the average life span of older panels. The panels would generate peak power for about ten years and then degrade over time. This was due to the gradual failure of the solar cells since as these older solar cells aged, they would start to fail. Since the solar panel was a collection of many of these cells it would still produce electricity, only less. The newer solar cells will last longer and will also generate more energy while they are viable. This means that a homeowner will enjoy their benefits for many more years, and makes their investment in solar energy technology an even better choice. Many people save a lot of money on the cost of a solar installation by making their own home build solar panel.
