These systems are renewable and inexhaustible because the sun rises up every morning to offer all heat energy.Īs a result, there’s no harm inflicted on the current environment. Solar power panels rely on the sun’s energy to convert photovoltaic energy into useful electricity. Why Choose Solar Panels to Charge Batteries?
Solar panel to charge 12v battery how to#
At first, the Battery will start to charge without any difficulties. Just like the examples above, a Solar Panel will charge a Regular Flooded type Car Battery in the same as any type of 12 Volt Battery. When you get into expanding your Small Solar System then make sure you size the components accordingly, especially the Charge Controller. You can expand this system which is great for camping and build it up by adding bigger Solar Panels and even Batteries. Purchase the 12 Volt Battery and Battery Box with it and you’re in business with all the components you’ll need to get you going. You can buy a Charge controller and Panels to expand as your needs require or start off with a simple beginner’s Solar kit like this one TP-solar 30W 12V Solar Panel kit Battery Charger Maintainer + 10A Waterproof Solar Charge Controller + Adjustable Mount Tilt Rack Bracket for Car RV Marine Boat 12 Volt Battery Off-Grid Other devices like a laptop or mobile phone whatever you desire. This simple setting will allow you to run the light or whatever load you need at your campsite or wherever you are and charge your battery during the day and use the appliance at night directly off the battery. You typically want to make sure you have a charge controller that is large enough to handle the amount of power and current produced by your panels. Charge controllers are sized depending on your solar array’s current and the solar system’s voltage. Overall though, sizing charge controllers is fairly straightforward.
This helps preserve the life and health of the batteries. They also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity and charging the batteries at the correct voltage level. We are using a 30-watt Solar Panel.Ī Charge Controller -prevents overcharging of batteries by limiting the amount and rate of charge to your batteries. You should have somewhere in the Ballpark the rating for the Panel. Test the Solar before you use it with a Voltmeter set to DC current laid out in the sun. First, connect the load from the Solar Panel to the Charge Controller which regulates the current to and from the battery. This size Solar Panel will normally give out approximately 18 to 22 volts.
The first component is the Solar Panel which could be any standard size normally as low as 3 and as high as 300-watt Solar panels.
