When sunlight hits the solar panel, it excites the electrons in the cells, creating an electric current that can then be harnessed for power.
Inverter
The electricity generated by the solar panels is in direct current (DC) form, which is then converted into alternating current (AC) by an inverter. AC electricity is what is used to power our homes and businesses, making the inverter a crucial component in the solar panel system. The inverter ensures that the electricity produced is compatible with our electrical devices and can be used efficiently.
Meter and Grid Connection
Any excess electricity generated by the solar panels can be fed back into the grid through a bi-directional meter. This process, known as net metering, allows you to earn credits for the excess electricity you produce, which can be used when your energy demand exceeds the solar panel production. By connecting to the grid, you have a reliable source of electricity when needed, giving you flexibility and ensuring a constant power supply.
Types of Solar Panels
There are several types of solar panels available on the market, each with its unique characteristics and benefits. Understanding the differences between these types can help you choose the right solar panel system for your needs and requirements.
Monocrystalline Solar Panels
Monocrystalline solar panels are made from single-crystal silicone, making them highly efficient in converting sunlight into electricity. These panels have a sleek black appearance and are space-efficient, making them a popular choice for residential installations. While monocrystalline panels tend to be more expensive than other types, their high efficiency and long lifespan make them a worthwhile investment in the long run.
Polycrystalline Solar Panels
Polycrystalline solar panels are made from multiple silicon crystals, giving them a speckled blue appearance. These panels are less efficient than monocrystalline panels but are also more affordable. Polycrystalline panels are a cost-effective option for those looking to install a solar panel system on a budget. While they may take up more space than monocrystalline panels, they still provide reliable power generation.
Thin-Film Solar Panels
Thin-film solar panels are made from a thin layer of photovoltaic material applied to a substrate like glass, plastic, or metal. These panels are flexible and lightweight, making them suitable for various applications, such as building-integrated photovoltaics (BIPV) and portable solar chargers.
