As mentioned earlier, solar generators consist of three primary components: a solar panel, battery bank, and inverter. Let’s take a closer look at how each component works together to produce electricity.

Solar Panel

The solar panel is the heart of a solar powered generator. It is made up of photovoltaic (PV) cells, which are responsible for converting sunlight into direct current (DC) electricity. PV cells are typically made of silicon, which is a semi-conducting material that can absorb sunlight and release electrons. When sunlight hits the surface of the PV cell, it knocks these electrons loose, creating an electrical current that flows through the cell. This current is then captured by the wiring within the solar panel and directed towards the battery bank.

The size and efficiency of the solar panel determine the amount of energy generated. The larger the solar panel, the more sunlight it can capture, and the more electricity it can produce. Efficiency refers to how well the PV cells can convert sunlight into electricity. Higher efficiency panels can produce more electricity with less surface area, making them ideal for smaller spaces.

Battery Bank

The battery bank is where the DC electricity generated by the solar panel is stored. It consists of one or more batteries, which are connected in a series to increase the voltage and amp-hour capacity. The voltage of a battery bank is determined by the number of batteries, while the capacity is determined by the type and size of the batteries.

When the sun is shining, the solar panel charges the batteries in the battery bank. The energy stored in the battery bank can then be used to power various electronic devices, even when the sun is not shining. The amount of energy that a battery bank can hold and for how long largely depends on its capacity. This capacity is measured in watt-hours (Wh) or amp-hours (Ah). The higher the Wh or Ah rating, the more energy the battery bank can store.


The inverter is the final component of a solar powered generator. Its role is to convert the DC electricity stored in the battery bank into alternating current (AC) electricity, which is compatible with most household appliances and electronics. AC electricity is the type of power that powers our homes and businesses. Without an inverter, the DC electricity produced by the solar panel and stored in the battery bank would not be usable.

Choosing the Right Solar Powered Generator

With so many options on the market, choosing the right solar powered generator can be overwhelming. Here are some essential factors to consider before making a purchase.

Power Output

The power output of a solar generator determines how many and what type of devices it can power. Generally, the higher the wattage, the more powerful the generator. When looking at power output, consider both the continuous wattage and the peak/surge wattage. Continuous wattage refers to the amount of power a generator can provide consistently, while peak/surge wattage is the maximum amount of power it can supply for short periods.

To determine the power output you need, make a list of all the devices you plan to power with the generator and their wattage requirements. Add up the continuous wattage of all the devices to determine the minimum wattage your solar generator should have. It’s always wise to choose a generator with a slightly higher wattage than your minimum requirements to accommodate for any surges in power.

Battery Capacity

As mentioned earlier, the battery bank is responsible for storing the energy produced by the solar panel. The capacity of the battery bank determines how much energy can be stored and for how long. When considering a solar generator, check the amp-hour (Ah) or watt-hour (Wh) rating of the battery bank. This will give you an idea of how long the generator can power your devices before needing to be recharged.

It’s also important to note that the battery capacity decreases over time. As the battery goes through more charge-discharge cycles, its ability to hold a charge diminishes, and it may need to be replaced. Look for generators with replaceable batteries to ensure that your investment will last longer.


The portability of a solar generator is another crucial factor to consider, especially if you plan to use it for outdoor activities or in remote locations. Look for lightweight and compact options that come with handles or wheels for easy transportation. Some generators also come with carrying cases or bags, making them even more convenient to take on the go.


Since solar generators are often used for outdoor activities, they should be able to withstand different weather conditions. Look for generators made of sturdy materials that are water and dust-resistant. A durable solar generator can last for many years, giving you a good return on your investment.

Solar Panel Compatibility

Most solar generators come with built-in solar panels. However, some models allow you to connect additional solar panels for increased charging capabilities. If you plan to rely heavily on solar energy, consider purchasing a generator that is compatible with external solar panels for faster charging times.

Installation and Maintenance

Solar generators are relatively simple to install and require minimal maintenance. Unlike traditional generators, they do not have any moving parts, which means they do not need regular tune-ups or oil changes. However, there are a few things you can do to ensure that your solar generator continues to operate efficiently.

Placement of the Solar Panel

The location of the solar panel greatly affects its ability to generate electricity. For maximum efficiency, the solar panel should be placed in direct sunlight. If using the generator indoors, place the solar panel near a window or use an extension cord to place it outside. Keep in mind that the angle of the sun also plays a role in the efficiency of the solar panel. Adjust the angle of the panel or move it throughout the day to capture the most sunlight.

Regular Cleaning

Dirt and debris on the surface of the solar panel can affect its ability to capture sunlight. Therefore, it’s essential to regularly clean the panel using a soft cloth and mild soap. Avoid using harsh chemicals or abrasive materials that could damage the panel.

Proper Storage

If you plan to store your solar generator for an extended period, disconnect the battery bank and store it separately. This will help preserve the batteries and extend their lifespan. Additionally, keep the solar panel and other components in a cool, dry place to prevent any damage.
