Guide to 12 Volt Solar Panels

12 Volt Solar panels are wall-mounted panels comprised of photovoltaic cells that convert sunlight to electricity via the photoelectric effect. The cells are constructed from sandwiched semiconducting materials (typically silicon). When these materials are exposed to sunlight, they emit electrons, which generate an electric current. While the majority of panels are rigid, thin-film cells enable semi-flexible and fully flexible versions.

Numerous people envision conventional 12-volt solar panels mounted on the roof. And it’s not difficult to see why. Solar panels operating at 12 volts are versatile, safe, and powerful enough for a wide variety of household and mobile applications. Due to the critical nature of solar panels in any installation, it is critical to conduct research. What factors should you take into account when shopping for solar panels? Are 12V or 24V panels more efficient, and how can their efficiency be maximized?

Should I choose a 12V system or do I require a 24V system?

Due to their versatility, 12 volt systems are the most popular choice for solar installations.

12v systems are suitable for a variety of situations, including the following:

1. Recreational vehicles/motorhomes/vans

2. Travel trailers for camping

3. Tiny house or small cabin

Typically, RVs and motorhomes come equipped with 12-volt batteries for lighting, hot water heater controls, air conditioning/heating controls, and refrigerators. As a result, it makes sense to use the voltage that the system is already operating at.

If your energy requirements range between 1,000 and 5,000 watts, consider a 24-volt system.

24 volt systems are ideal for the following applications:

1. Mansions and apartment complexes

2. Industrial and commercial structures

3. Parking garages

How do I determine whether components in a 12V or 24V system are compatible?

If you purchase a 12-volt solar panel, you should also purchase a 12-volt battery, a 12-volt inverter, and at the very least a 12-volt charge controller. A 24-volt solar panel should be used in conjunction with a 24-volt battery bank, a 24-volt inverter, and at the very least a 24-volt charge controller. Due to the lack of a 24v battery, you will need to connect two 12v batteries in series in a battery bank.

Additionally, it is critical that your solar panel’s rating does not exceed that of your charge controller, so be sure to check the specifications of your charge controller. If your solar panels are 12 volts and your amps are 14, you will require a charge controller with a minimum of 14 amps. However, you must factor in an additional 25% due to environmental factors. This increases the minimum amps required for this charger controller to 17.5 amps. In this case, a 12 volt, 20 amp charge controller would be required.

Conclusion

As you can see, installing 12-volt solar panels is an excellent way to increase your energy independence, lower utility costs, eliminate the need for gas-powered generators, and ensure reliable access to energy when you need it. As technology and efficiency improvements, and costs decrease, there has never been a better time to go solar.
