5 Best 100-watt Solar Panel Kit

5 Best 100-watt Solar Panel Kit

The immense popularity of 100-watt solar panels is understandable. Compact, portable, easy to set up, and more than anything else, affordable – no wonder 100-watt solar panel kits are in high demand.

Before we go further, you may want to know that a 100-watt solar panel cannot power most of your home appliances. In other words, this is not a choice for home solar installation. These are much smaller in size and capacity.

A 100-watt solar panel finds its use in supplying power to a range of small electronic and electrical devices around your home, whose power requirement is within 100 watts. Such as laptops, phones, WiFi routers, tablets, LED TVs, LED lights, and ceiling fans. You can find out the wattage of an electrical device by checking the label. So long as the wattage is within 100 watts, you can use a 100-watt solar panel to charge it. 

Now that this point is cleared, let us move on to the practical aspects of using a 100-watt solar panel. As you know, solar panels produce electricity only when the sun is shining. In other words, it cannot generate energy at night. If you are looking for a power source that is available 24×7, you should consider teaming the solar panel with a storage device. A solar battery can store the excess energy produced during the daytime for use at night.

Even if there are limitations where a 100-watt solar system can be used, it is still a good buy because it can power most of your essential devices when you are unable to access grid power. When you are traveling, camping, or in an RV or a boat, this small wonder can provide enough juice to help you stay connected with the outside world.

Read on to learn more about 100-watt solar panel kits and how to make the best use of them. In this article, you will find a list of the best 5 100-watt solar panel kits available on the market to help you harness the free renewable energy available to you.

    What comes in a 100-watt solar panel kit

    As it says in the product name itself, these are solar panel kits and not merely solar panels. Let’s see what all are included in a solar panel kit.

    Here are the common components you can expect in solar panel kits.

    1. Solar panel: 

    That is a no-brainer! How can a solar power system work without solar panels? The capacity of the solar panel is measured in terms of wattage.

    2. Charge controller: 

    Merely generating electricity is not enough to charge your devices. A charge controller is a device that regulates and transmits the power produced by the panel. It prevents common charging issues like overcharging, overheating, short circuits, and reverse polarity. 

    3. Mounting hardware: 

    Unlike bigger solar installations, solar kits are smaller units with an emphasis on compactness and portability. The solar panels in these kits already come mounted in frames, often with kickstands, or will have pre-drilled holes for easy mounting.

    4. Cables and tools: 

    These may not seem very important but are an inevitable part of a solar panel kit to help make the installation process simple and easy.

    5. Inverter: 

    A solar energy system cannot function effectively without an inverter. It is the inverter that converts the DC power produced by the solar panel into usable AC power. However, you may not find this component in many solar panel kits. You may have to buy it separately.

    6. Battery: 

    This is an optional but desirable addition to a solar power system. This can be useful in storing the energy produced for later use. A battery is extremely useful for drawing power from the panel at night. Ensure that the voltage of the battery matches that of the solar panel.

    Tips for selecting the best solar panel kit

    Here are some of the factors you should consider when choosing a solar panel kit.

    Power demand: 

    What are your electricity expectations from the solar power system? As the solar panel kits are usually chosen based on their capacity, which is measured as their wattage, knowing your power requirements can make the decision easier. 

    You need to remember that the higher the wattage, the more power you get from the solar systems. But the price of the kit will go up and the solar system gets bulkier. 

    If you are not sure about your requirements, you can start with a basic kit and one solar panel and add more to the setup. 

    Component quality: 

    Invest time in understanding the components included in the kit. Go for a solar kit offering monocrystalline panels. Though costly, they are more efficient. This means that even with a smaller panel and poor light, you will get more power. 

    Pick a kit with a charge controller with higher wattage so that you can expand the capacity of the kit later on. Another point to verify is whether the charge controller offers protection against common charging issues. Choose one with an LED display for ease of use.

    Brand value and warranty: 

    This is a major consideration to ensure the lifespan of the solar systems. Read the fine print to know the terms of the warranty. Check reviews and feedback of genuine buyers to confirm that the kit will deliver what it promises.

    Bottom line

    The solar kits have similar components with a few extra features added here and there to appeal to specific buyers. So, it is up to you to understand your requirement and seek out the right solar panel kit to meet your power needs.

    Often when buying solar equipment, you tend to focus on the price and features and neglect the quality aspect. Not all solar kits are made the same. And, this is the primary reason for the wide variation in their prices. The general rule of thumb is that the more you pay, the better product you get. The brand name also carries a weightage and does matter in the final decision-making.

    Solar panel kits bring together various components of a solar system into one package to avoid the hassle of shopping for each one of them separately. Among the kits available in the market, Renogy solar kits are way ahead of the rest.

    A point worth mentioning here is that most kits do not offer inverters or batteries. You need to buy an inverter to start generating solar energy. Pairing them with deep-cycle batteries can help you get more out of them. You may also want to take a look at our guide on buy solar panels for home.
