We depend heavily on oil, coal, and natural gas, all forms of non-renewable sources of energy that are not clean and emit carbon dioxide and other greenhouse gasses in the environment. A study published shows that around 80 percent of the world’s energy requirement is met by fossil fuel sources. This dependency on carbon-rich fuels has accelerated the triple planetary crisis, climate change being one of them.
To address these triple planetary crises, one of the solutions is to transition towards renewable energy sources like wind, solar, and hydropower. A solar-powered generator is one such innovative solution that harnesses solar energy from the sun and converts it to electrical energy. In this article, we’ll discuss A-Z about a solar-powered generator.
1. How does a solar powered generator work?
A solar powered generator works by converting the sun’s energy into electrical energy. It consists of different components that come together and form a portable system that can be used in cases of emergencies when the main power grid is down. These solar powered generators come in different sizes and functions and supply power to various power-dependent devices.
A solar powered generator consists of solar panels, a charge controller, a battery, and an inverter. These are crucial components, and even one missing component will disrupt the whole system.
The process starts when the solar radiations hit the solar panels, which are composed of many small units of photovoltaic cells.
These solar panels convert solar energy into electric energy, but this electricity is in the form of Direct Current (DC) which cannot be used directly. This Direct Current is then directed to the charge controller that stabilizes and regulates the current before storage. Now, the battery bank then stores this energy until it is further needed and then releases it through the inverter in the form of stable Alternate Current (AC).
2. The cost-effectiveness of solar powered generators
At first, you will think that a solar powered generator might not be a cost-effective option because it probably costs more than a fossil fuel generator. A typical solar powered generator can have an average cost of around 2,000 dollars. This varies depending on the size; the smaller solar powered generators can be sufficient to charge cellphones and laptops, while the bigger ones have the capacity to power a small house for a few hours when the power grid is down.
Although you do pay a higher price initially, a solar powered generator does not need much maintenance, and the running of the device is smooth. So, despite the overall initial high cost, you can save on maintenance. They are quiet compared to fossil fuel generators and have fewer moving pieces. And also you don’t have to go and keep buying fuel to run it. After the initial purchase, you don’t need to spend a lot, and they make a good choice since they are portable and are easy to set up.

Check and tighten all the connections in your portable solar powered generator, as movement (traveling or transportation) might loosen the connections over time, affecting the system’s performance.
Batteries can degrade over time, so make sure to keep a check on the battery and inspect it regularly. Start by checking the battery terminals for corrosion, and if you find any wear or tear, clean it up and apply a protective layering to it to prevent further damage.
Keep a regular check on the performance of your solar powered generator, especially on the factors like the battery’s charge level and the system’s voltage. If you notice any irregularities, then it’s a sign that something is wrong. Also, when not in use, make sure the solar-powered generator is stored properly. It will protect the system from damage and will ensure it’s ready to use when needed.
4. Lifespan and durability
The lifespan and durability of a solar-powered generator depend on many different factors, such as the quality of all the components used, the frequency of usage, and the maintenance of the system. If your solar-powered generator is very well maintained, it can last up to 20 years, thus making it a worthwhile investment for your home, weekend getaways, or business.
Also, it is important to know that the lifespan of your solar-powered generator will depend on the type of battery you’re using in the device. Most solar powered generators use durable lithium-ion batteries, which have a longer lifespan of about 10 years with minimal maintenance. Thus, making it an ideal choice for your solar powered generator. Also worth noticing is the fact that the number of charge-discharge cycles that the battery can handle plays a significant role in determining the lifespan of a solar-powered generator.
Not to mention that the quality of the solar panels will prolong the lifespan of a solar-powered generator. High-quality solar panels are made to withstand extreme weather conditions like hail and storms. Thus, when all the components used are of good quality and maintained properly, they will ensure maximum returns on your investments.
5. Portability and use-cases
One thing that makes a solar powered generator a favored choice is that they are portable.
