How to Charge a Battery from Solar Panels?

These instructions will show you, with step-by-step videos, one of the foundational skills of building DIY solar power systems: how to connect a solar panel to a battery. By the end, you’ll be charging your 12-volt battery — or higher — with free solar energy.

This article will cover both the situations in which you can connect the panel and battery directly and the situations in which you should never attempt to do so. We’ll also examine the suggested course of action and the justifications for it. Hopefully, this will answer your queries.

How to Charge a Battery With a Solar Panel?

Using a solar panel to charge your batteries is a fantastic way to generate clean, renewable energy. Before you begin, you must install a charge controller, which controls the voltage being transferred from the solar panel to the battery.

How to Charge a Battery from Solar Panels?

Purchasing a Charge Controller

  1. The wattage of your panel should be visible on the back. Your solar panel should typically have a sticker on the back indicating the wattage it will generate. For instance, if your panel has 300W listed on the back, it means that the array can produce 300 watts of power.

  2. Subtract your battery’s voltage from the solar panel’s watt rating. Usually, the battery will have the voltage listed on it. Divide this number into the wattage that was listed on the back of your solar panel. You will get the amps needed for your charge controller to safely charge the battery from this.

How to Charge a Battery from Solar Panels?

  1. Choose an MPPT charge controller for better efficiency. Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM) are the two primary categories of charge controllers.

  2. For a cheap solution, buy a PWM charge controller. A PWM charge controller can be a good place to start if you’re new to solar power experimentation. The battery is charged by these controllers using energy pulses, and they keep an eye on the battery’s power to prevent overcharging.

How to Charge a Battery from Solar Panels?

Setting Up the Controller

  1. Mount the charge controller away from the elements and on a solid surface. Charge controllers are not weather-proof, so they shouldn’t be installed outside, even if your solar panels are permanently mounted in place. Instead, locate a remote location to install the charge controller and then run wires from the panel to the controller.

How to Charge a Battery from Solar Panels?

  1. To your battery, attach a positive and a negative wire. You can accomplish this by either using bare wires and clamps to hold them to the battery posts or by using wires with ring connectors that fit over the posts.

  2. Slide the wire ends into the charge controller’s input ports. Normally, no type of connector is required on the ends of the wires that plug into the charge controller. Instead, insert the bare positive and negative wire ends into the corresponding ports, and then tighten the screws holding the wires in place with a screwdriver.

How to Charge a Battery from Solar Panels?

  1. The wires should be joined to the charge controller using MC4 connectors. MC4 connectors, which are lengthy cylindrical fittings with a male and a female side, are typically used to connect the output wires on solar panels.

  2. Connect the wires from the controller to the solar panel. After connecting the input wires to the charge connector, there should be 2 loose wires left with an MC4 connector on each end.

  3. Check the output on the charge connector to make sure it’s working. The output that is flowing to the battery is typically displayed on a digital screen on charge connectors.

  4. Till it is charged, keep the battery connected to the connector. The size of the solar battery you’re using, the solar panel’s wattage, and even the weather that day will all affect how long it takes to charge your battery.

How Does a Lead-Acid Battery Work?

The working principle of lead acid battery is easy. Simply put, when the sulfate in the sulphuric acid bonds to the lead, the battery’s electrical charge is produced. Reversing this reaction will replenish the electrical charge. In other words, the sulfate reacts with sulphuric acid once more to recharge the battery. The sulfate ions in the acid are obviously limited in number.

What Are Lead Acid Batteries? a Complete Guide

Additionally, the lead it bonds to has a finite surface area. Consequently, the charge deteriorates as the sulfate is consumed.

Because of this, lead-acid batteries are not recommended for continuously operating devices. They work best, however, for applications that demand a quick burst of strength.
