    Find out More About Solar Panel Basics

    • 5 min read

    Solar panels are devices that convert sunlight into electricity. They harness the power of the sun's rays to generate clean and renewable energy. Installing a solar panel on your roof comes with many benefits. It is a path leading to a sustainable future. Let us find out more interesting facts about this solar energy provider.

    What is a Solar Panel?

    Solar panels are devices that capture the energy from sunlight and convert it into electricity. Solar energy is the most popular renewable energy source today, therefore many homeowners across the globe switched to using solar panels as they bring many advantages.

    The main components of a solar panel include the PV cells, a glass cover that protects them, and an encapsulant material that holds everything together. The glass cover is transparent to allow sunlight to reach the PV cells while protecting them from external factors. The encapsulant provides structural support and protects the cells from moisture and mechanical damage.

    The electric current generated by the PV cells is collected by metal conductors called busbars, which then transfer the electricity to the output terminals. The output terminals connect the solar panel to an electrical system, allowing the generated electricity to be used to power various devices and appliances.

    How Does a Solar Panel Work?

    Solar panels work by harnessing the energy from sunlight and converting it into electricity. They contain photovoltaic (PV) cells made of semiconductor materials, typically silicon. When sunlight hits the PV cells, the photons in the sunlight excite the electrons in the cells, creating an electric current. This process is called the photovoltaic effect.

    The generated electricity is then collected and transferred through metal conductors to the output terminals of the solar panel. From there, the electricity can be used to power homes, businesses, and other electrical devices.

    How To Install a Solar Panel System?

    When installing a solar panel, it's important to consider the location and angle for optimal performance. Solar panels work best when they receive direct sunlight. Therefore, it's ideal to install them in a location that receives maximum sunlight throughout the day, such as rooftops, open fields, or areas free from obstructions like tall buildings or trees.

    The angle at which the solar panel is installed also affects its efficiency. The angle should be adjusted according to the latitude of the installation site to maximize solar energy absorption. In general, for locations near the equator, the optimal angle is around 30-40 degrees.

    If installing on a rooftop, ensure that it has adequate structural support to bear the weight of the solar panels. Additionally, consider the orientation of the roof. South-facing roofs typically receive the most sunlight in the northern hemisphere, while north-facing roofs are more suitable in the southern hemisphere.

    Avoid shading the solar panels for optimum performance. Even partial shading can significantly reduce their efficiency. Trim or remove any overhanging branches or objects that may cast shadows on the panels throughout the day.

    Professional installation is recommended to ensure proper wiring, mounting, and connection to the electrical system.

    What to Look for When Buying a Solar Panel System?

    When buying a solar panel system, there are several key factors to consider to ensure that you get the most efficient and durable product for your needs.

    Conversion Efficiency: This refers to how well the solar panel can convert sunlight into energy. The higher the efficiency, the more power you can generate. Typically, a conversion rate of 15-20% is considered good, while 20-23% is excellent. Anker 625 Solar Panel boasts an impressive 23% conversion efficiency, making it a great choice for those who want to get the most out of their solar power system.

    Durability: A solar panel system is a long-term investment, so it's important to choose a product that will last. Look for panels that are made from high-quality materials and are scratch and weather-resistant. This can help ensure that the system will withstand harsh weather conditions and last for years to come.

    Sunlight Alignment: Some solar panels are equipped with technology that allows them to adjust to the angle of the sun, ensuring maximum exposure and efficiency. This can help you get the most out of your system and generate more power. Our Suncast technology ensures that the panel is properly aligned to capture direct sunlight for maximum charge, even on cloudy days.

    Certification: Look for solar panels that have been certified by reputable organizations, such as the International Electrotechnical Commission (IEC) or Underwriters Laboratories (UL). This can provide peace of mind that the panels meet strict quality and safety standards.

    Warranty: A good solar panel system should come with a warranty that covers defects and ensures the system will operate as advertised. Look for a warranty of at least 10 years to help protect your investment.


    The use of solar power is rapidly gaining momentum. With more and more people realizing the cost efficiency, sustainability, and environmental benefits that solar panel systems can provide, it makes sense to look into this renewable energy technology. Choosing the right system for your needs can seem intimidating, but with a little bit of research and some careful planning you can be sure to make the most efficient investment for your home or business.  Invest in a reliable solar panel system and you will be able to enjoy clean energy with little maintenance for years to come. Good luck in taking this important step towards green living!


    How many things can you run off of a 100-watt solar panel kit?

    The number of things you can run off a 100-watt solar panel kit depends on the power consumption of each device. A 100-watt solar panel can produce up to 100 watts of power under optimal conditions. You can run small appliances and devices such as LED lights, a small fan, a smartphone charger, or a laptop.

    What are the 3 pros of using solar panels?

    1. Renewable and Sustainable: Solar panels harness energy from sunlight, which is an abundant and renewable source of power. Unlike fossil fuels, sunlight is not depleted, making solar energy a sustainable solution that helps reduce dependence on finite resources.
    2. Environmentally Friendly: Solar panels produce clean energy without emitting harmful pollutants or greenhouse gases. By utilizing solar power, we can mitigate the negative impacts of climate change, promoting a greener and healthier environment.
    3. Cost Savings: While the upfront cost of installing solar panels may be a significant investment, they offer long-term financial benefits. Solar energy can help reduce or even eliminate monthly electricity bills, providing substantial savings over the system's lifespan.

    How long do solar panels last?

    Solar panels are designed to be durable and long-lasting. On average, solar panels have a lifespan of 25 to 30 years. However, this does not mean they stop working after this period. Most manufacturers provide performance warranties that guarantee the panels will still produce a certain percentage of their original power output after a specific number of years, usually around 80% at the end of 25 years.
