Solar panels are becoming increasingly popular as a source of renewable energy. They can help homeowners reduce their electricity bills, lower their carbon footprint, and even earn money by selling excess energy back to the grid. But what exactly are solar panels, how do they work, and are they worth the investment? In this ultimate guide, we'll explore everything you need to know about solar panels.
What is Solar Panel?
In simple, the solar panel is a new invention that converts the sun into light. In the professional aspect, the solar panel is used for transferring the articles of energy called "photons" into electricity. Also, the solar panel is used to power the electrical load.
It usually can be divided into two types ---- Monocrystalline solar panel ( or mono solar panel) and polycrystalline solar panel. The mono solar panel is made from solar panel monocrystalline. The solar panel monocrystalline grows for creating solar panels. The poly solar panel contains several crystals of silicon in a single PV cell.
How Does Solar Panel Work?
The solar panel consists of several individual flexible solar module which is made of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). During flexible solar module absorb the photons, they would generate the electric current.
Here is the process of initate the electric current. First, the photons from the sun strikes the surface of the solar panel and generate the energy. Second, this energy not only would knock the electrons out of their atomic orbits and release tehm into the electric field generated by the solar cells. Third, the free electronics also woul be pull into a directional current. In the industry, this process is called Photovoltaic Effect.
How Long Does Solar Panel Last？
Solar panels have a lifespan of about 25-30 years on average. However, this lifespan can vary depending on several factors such as the quality of materials used in manufacturing, the climate and weather conditions in the area where the panels are installed, and the maintenance and care provided to the panels over time.
It's worth noting that while the panels may continue to generate electricity after their estimated lifespan, their efficiency may decrease, which means they won't produce as much energy as they used to when they were new. In some cases, solar panels may require maintenance or repairs to continue functioning properly, which can extend their lifespan.
Are Solar Panel Worth It?
Yes, solar panels are definitely worth it. While the initial cost of installing solar panels can be higher compared to traditional sources of energy, such as fossil fuels, the benefits and cost savings over time make them a wise investment.
●Firstly, solar panels provide clean and renewable energy, which reduces carbon emissions and helps to combat climate change. This is a significant benefit for the environment and public health.
●Secondly, solar panels can help homeowners and businesses save money on energy bills over the long term. Once installed, solar panels can generate electricity for free, which can significantly reduce or even eliminate energy bills. In addition, many governments and utility companies offer incentives and rebates for installing high efficiency solar panel, which can help to offset the initial installation costs.
●Thirdly, solar panels can increase the value of a property. Homes and businesses with solar panels are more attractive to buyers because they offer a sustainable and cost-effective energy source, which can increase the property's resale value.
How Many Solar Panels Do I Need？
To get an accurate amount of solar panels you use, you need to make a calculation. Multiply the household's hourly energy requirement by the peak sunlight hours for your area and divide that by a panel's wattage.
According to the above formula, several factors determines the number of solar panels you will need:
●Your energy consumption: The amount of electricity you use will determine the size of the solar system you need. If you use more electricity, you will need more solar panels to meet your energy needs.
●Your location: The amount of sunlight your location receives will affect the amount of electricity your solar panels can generate. If you live in a sunny area, you may need fewer solar panels than if you live in a cloudy or shaded area.
By the way, it also relates to the solar panel mounting. If you mount the solar panel in a shady place, the electricity the panels generate would be less than the mount the solar panel in the sunny place.
●The size of the solar panels: Solar panels come in different sizes, and the size you choose will affect the number of panels you need. Larger panels can generate more electricity, so you may need fewer of them.
●The efficiency of the solar panels: Solar panels have different levels of efficiency, which affects how much electricity they can generate. Higher-efficiency panels may cost more, but they can generate more electricity, so you may need fewer of them.
To determine how many solar panels you need, you should consult with a professional solar installer who can assess your energy needs and recommend a system that is tailored to your specific circumstances.
