Why do solar panels need a controller?

The main role of a controller is to protect and automate the charging of the battery. It does this in several ways: 1. REDUCING THE VOLTAGE OF YOUR SOLAR PANEL Without a controller between a solar panel and a battery, the panel would overcharge the battery by generating too much voltage for the battery to process, seriously damaging the battery.

How does a solar controller work?

It delivers power from the PV array to system loads and the battery bank. When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off. By being able to regulate the voltage, the solar controller protects the battery.

What does a solar charge controller do?

What a solar charge controller does Think of a solar charge controller as a regulator. It delivers power from the PV array to system loads and the battery bank. When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off.

Do solar panels need a charge controller?

Block Reverse Currents: Solar panels pump current through your battery in one direction. At night, panels may naturally pass some of that current in the reverse direction. This can cause a slight discharge from the battery. Charge controllers prevent this from happening by acting as a valve. DO YOU ALWAYS NEED A SOLAR CHARGE CONTROLLER?

Do I need a charge controller for a 7 watt solar panel?

You don't need a charge controller for a 7-watt solar panel. These panels are specifically designed for low-voltage trickle charging, which means you don't have to worry about regulating the electrical flow. Looking for a comprehensive guide on solar charge controllers?

How long does a solar charge controller last?

When using the right charge controller the lifetime of your battery bank can easily be extended with several months. As a charge controller only accounts for a small portion of the overall solar system cost, it’s highly recommended to purchase a quality charge controller. [...]
