One of the main reasons that can cause problems with your solar panel is a malfunctioning PWM solar controller. A PWM solar charge controller controls the amount of power the solar panel receives from the batteries. It uses analog circuits so you have to be careful when choosing one.
Most people think that any controller is PWM. That's not true. Many solar manufacturers sell solar panels that can be used with any solar controller they sell. To avoid confusion, check the instructions carefully before you install them.

The first thing you should look for in a PWM solar controller is an operational temperature scale. A temperature scale will tell you how hot or cold the solar cells need to be to operate properly. If you install a temperature scale, it can save you a lot of money in the long run because you won't have to re-warm the cells in the winter months and so on.
Another important feature to look for is a digital readout. Digital readouts are the best since the controller will always be showing you what you want to know. Digital readouts also eliminate the need for temperature sensing so you don't have to worry about it freezing.
You should consider a PWM and an intelligent solar charge controller. An intelligent solar charge controller keeps track of the level of energy in each cell. The higher the energy level the more solar energy it can collect. They can be added, subtracted, or even changed on a continual basis to control the amount of solar energy you collect.
If you use a traditional charge controller, you would have to change the cells every time. Now you can change the cells on the fly without worrying about overloading your charge controller. This makes life much easier. When a person is doing solar charge controller installations they should be careful to check the digital readout properly.
Another feature to look for is a DC to DC converter that will take the energy from the solar charge controller and convert it into DC current. Many solar charge controllers work with a specific brand of an inverter. With this type of solar inverter, you will want to make sure that you use a certified inverter. Certified inverters are designed to give you the cleanest and most reliable power possible.
Some people do a great job and some don't. There are plenty of companies out there that sell solar charge controllers but not all of them are the same(MPPT solar controller: PWM and MPPT charge controller). What you really want is a company that has a good reputation for selling quality solar charge controllers.
You should check the size of the solar charge controller before you purchase it. If you buy a large one you might have trouble attaching it to your system. You can get them larger for smaller systems if you need to.
The type of control you will need is another important factor to consider when buying a solar charge controller. The PWM solar charge controller does not have a digital readout but instead only operates on the analog outputs from the batteries. This means you'll be able to program how much power your system will use and it won't waste power. A PWM solar charge controller will also make sure that you always have enough power available to the inverter.
Look for an intelligent solar charge controller that can be adjusted from sunrise to sunset. This can help a lot in the long run since it will help reduce the amount of voltage in the system. It also helps the voltage stays constant during the day. The major problem with a PWM solar charge controller is that it will take longer to charge the batteries as the sun moves across the sky.
Don't take for granted the features of a PWM solar charge controller. They are an important part of your solar system and your solar panel will run much more efficiently if you choose one that has the right characteristics. One way to tell if a solar charge controller has the features you want is to test it yourself.
