How do solar panels generate electricity?
Solar panels generate electricity through the photovoltaic (PV) effect. When sunlight hits a solar panel, the light energy is converted into electricity. This process is also known as PV effect, which is why solar panels are called photovoltaic panels or PV modules.
Why are solar panels called photovoltaic panels?
Solar panels are also known as photovoltaic panels (PV panels or PV modules) because they generate electricity through the photovoltaic (PV) effect. This process converts sunlight, both direct and diffuse, into electricity.
What is the photovoltaic effect?
When sunlight hits a solar panel, the light energy is converted into electricity. This process is known as the photovoltaic (PV) effect, which is why solar panels are also called photovoltaic panels, PV panels or PV modules.
How do photovoltaic solar panels work?
Photovoltaic solar panels are much more common than those that utilize thermal conversion, so we’ll be focusing on PV solar panels. Sunlight strikes the solar cells of the solar panel. Some of the rays of light or photons pass through the outer layers of the cell and into the silicon core.
Can photovoltaic panels produce electricity?
Depending on the construction, photovoltaic panels can produce electricity from a specific range of light frequencies. However, in general they cannot cover the entire solar range. In particular, photovoltaic cells cannot convert ultraviolet , infrared and low or scattered light into electricity.
How do solar photovoltaic cells convert sunlight to electricity?
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology.

High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
