What is a photovoltaic (PV) solar panel?
This solar panel is a photovoltaic (PV) panel that offers several advantages over the standard solar panel size, making them a good alternative. Some of the benefits of this solar panel type include: Sleek weight and flexibility – because of its weight, this solar panel is easier to install in different locations.
What are the dimensions of solar panels?
Most solar panels are about 1.5 inches thick. The typical classification of solar panel sizes based on solar cell size is less useful for practical calculations.
How big are residential solar panels?
Most residential solar panels are 1.7m tall x 1.0m wide (or 1.7 m2), with a maximum power output of around 330W. Solar panels also come with 72 solar cells, which are larger to accommodate the additional cells. They are around 30% larger than residential solar panels, measuring approximately 2.1m tall x 1.1m wide (or 2.3 m2).
How many Watts Does a solar panel have?
Residential solar panels typically possess between 250W to 450W depending on how efficient they are in converting sunlight into energy and the solar panel sizes. Solar panels are available in a wide range of sizes, types, and total wattage. The standard solar panel size measures an average of 5.4 by 3.25 feet or 65 by 39 inches.
What is the typical thickness of solar panels?
Most solar panels are about 1.5 inches thick. This is the typical classification of solar panel sizes (based on the solar cell size). It’s a bit theoretical and quite useless for most calculations.
How much power does a solar panel produce?
The higher the rating is, the higher the solar power that is produced. Residential solar panels typically possess between 250W to 450W depending on how efficient they are in converting sunlight into energy and the solar panel sizes. Solar panels are available in a wide range of sizes, types, and total wattage.
Featured Solar Products

They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
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.
