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.
This can be achieved if the nominal voltage of the panel is lower than 17-18V, and if the solar panel is a lot smaller than the charging battery e.g.. a 10W panel charging a 100Ah battery. There are many different types of controllers on the market. Choosing the right controller depends on the solar power system you would like to generate.
More importantly, your solar charge controller must be able to handle the maximum voltage that the solar panels / solar array can produce. This is the controller’s maximum input voltage. To calculate the maximum input voltage, you need to work out the maximum output of the solar array.
The Outback Flexmax FM80 is one of the best solar controllers on the market as it supports a wide variety of system designs and battery types. With a huge max input voltage capacity, the Outback controller is perfect for off-grid systems that people install on roofs or rural areas.
MPPT controllers can work well where the array voltage is higher than the battery voltage. The distance between the solar panels and the battery bank will impact the performance of the system due to ‘voltage drop’ as the charge travels along the wire from the panels to the charge controller and the batteries.
• Certain low-voltage appliances must be connected directly to the battery. • The charge controller should always be mounted close to the battery since precise measurement of the battery voltage is an important part of the functions of a solar charge controller.
How to choose a Solar Charge Controller :: 12V solar panels …
MPPT controllers are the most efficient and powerful controllers that we offer, but they should only be used when the solar panel voltage is much higher than the battery voltage. An MPPT system is able to lower the voltage of a panel (or an array of solar panels) that is up to ten times higher than the voltage of a battery to match the voltage ...

Solar Panels On Cars: Everything You Need To Know
Panels can use solar energy at around 60% efficiency, but only if getting direct sunlight. Any time spent in a parking garage or under some sort of shade will kill that efficiency. Solar panels also lose 25-30% of their efficiency if they are sitting flat on the roof of your car, all thanks to the earth shifting away from the sun throughout the day. Solar panels, even flexible ones, aren''t ...
