If you have been using a solar panel, you know that having a solar voltage regulator is incredibly essential. Any solar energy system, including solar panels, need solar regulators for them to function correctly. Why, then, do we need to use a solar regulator when using a solar panel?
Even though solar panels have been in existence for many years, the early aughts have started using solar panels for home and recreational use. The good thing about solar panels is that they can be used for a wide array of reasons.
The wide range of solar energy is why residential solar homes are using solar water heating, making it a common and popular thing today.
Solar energy is free, and many people have started to know the advantages of using solar as a renewable energy source. Recently, many homeowners have started installing solar roof tiles, which have the ability to capture a significant amount of solar energy that can be used to power a lot of home appliances around your home or even outside your property.
With solar energy, solar users are able to tap into a renewable free, plenty, and clean energy source, which does not affect the surrounding in any way at all. Solar energy can be used almost anytime and anywhere you can imagine.
It can be used for power and heating in homes, cultivating solar power to run home appliances, like electronics, stoves, washers, dryers, and lights. You can use solar energy to heat water to use in your shower and bath tabs, cooking, heating a swimming pool, and even laundry.
Solar energy can also be used outdoors for solar-powered string lights, garden ornaments like birdbaths, fountains, lamps, and many more. Solar power has also started to branch out into the automobile industry.
Companies are manufacturing vehicles that use solar panels as their source of power to operate. Solar energy can be used for commercial use and can also be used for recreational purposes like in vehicles, aircraft, scooters, boats, and many more.
A solar regulator is a small box consisting of circuitry in a solid-state located between a solar panel and a battery. The solar regulator’s work is to control the amount of solar charge going from the solar panel flowing to the deep cycle of the battery bank. The regulator prevents the battery from overcharging to preserve the health and life of the battery.
So, a solar regulator’s central role is to keep your battery from being overcharged by the energy gotten from the solar panel. This will extend the life of your battery, and you will not need to replace them often.
The solar regulator can protect your battery by disconnecting the solar panel from sending more energy to the battery.
In conclusion, therefore, a solar regulator is a switch that controls the currents and voltage coming from the solar panel to the battery. There are many types of solar regulators out in the market, and knowing one which is best for you can be tedious work. So how do you know which solar panel regulator is right for you?
You will need to do a little research and get to know the ones available in the market. You will need to check for things like the regulator’s efficiency rate, price, durability, quality, and other features before settling on one device.
The amperage ratings should also be put into consideration. It is important to note that most PV charge regulators come in 12, 24, and 48 volts. The amperage should be between 1 to 60 amps, and voltage ratings should be 6 to 60 volts. Before buying a solar regulator, you should check if it is compatible with your solar panel in terms of make and design.
Check if the voltage systems are compatible and make sure you select the product that can handle the maximum output current of your solar panel array. Once you have figured out the answers to those questions, you can then go ahead and select the product that is right for you.
It can look like a daunting task, but fortunately, we have compiled for you 10 of the best solar voltage regulators available in 2020 and their reviews. This article will get to know the different types of solar regulators that exist on the market.
We will look at different factors like design, efficiency, quality, price, and many other features. So, without further ado, let us jump straight to some of the best solar voltage regulators.
