What is a parabolic trough solar collector?
A parabolic trough solar collector can be used as a concentrating photovoltaic (PV) system. In this type of system, concentrated sunlight is used to generate electrical power. The collector consists of a parabolic reflector that focuses the sun’s energy onto a small area. This focused energy is then used to generate electrical power using PV cells.
What are parabolic troughs in CSP?
In solar thermal energy, all concentrating solar power (CSP) technologies use solar thermal energy from sunlight to make power. Parabolic troughs are one type of CSP technology, seen in the rows behind the Tower CSP plant in the image. They are also known as Trough CSP plants.
What is a trough solar collector field?
A trough solar collector field is a collection of parabolic trough-shaped mirrors arranged in parallel rows. These single-axis mirrors track the sun from east to west during the day, ensuring that the sun is continuously focused on the receiver pipes.
What is concentrating solar power (CSP)?
Concentrating solar power (CSP) is a solar thermal energy technology that uses sunlight to generate power. It concentrates the sun's energy onto a receiver, which traps the heat and stores it in thermal energy storage. This stored heat is then used to create steam to drive a turbine and produce electrical power.
How does a helium trough solar collector work?
Helium is an excellent working fluid for parabolic trough solar collectors, provided the operating temperature is 700K and below. The heat engine is an external combustion engine that heats and cools a working gas sealed in a cylinder. It converts thermal energy to kinetic energy.
What is the working fluid for a parabolic trough solar collector?
The most common working fluids for parabolic trough solar collectors are water and air, but other fluids such as helium can also be used. The main advantage of using water as the working fluid is that it’s a renewable resource. The disadvantage is that water can evaporate, which can cause the system to lose efficiency.

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.
