What is thermal energy storage?
Thermal energy storage in buildings can be used to adjust the timing of electricity demand to better match intermittent supply and to satisfy distribution constraints. TES for building heating and cooling applications predominantly utilizes sensible and latent heat technologies at low temperatures (i.e., near room temperature).
What is energy storage?
A crux is the time-scale mismatch between energy supply and demand, which limits high-efficiency and large-scale utilization of renewable energy sources such as solar energy and wind energy, industrial waste heat, and off-peak electricity. Energy storage is to serve this kind of scenario and decouple supply and demand in energy systems.
How do heat storage units work with solar power generation systems?
In indirect systems, on the other hand, TES units remove the mismatch between supply and demand. The basic concepts of each method and the implementation of heat storage units with solar power generation systems are discussed below. Sunlight is directly converted into electricity by using semiconductor cells in photovoltaic panels (PVPs).
Does thermal energy storage combine sensible and latent heat storage?
Thermophysical heat storage combining sensible and latent heat storage is reviewed. Performance evaluation of thermal energy storage is improved. Universal technical characteristics and performance enhancement are analyzed. Working principles, developments and challenges for different applications are discussed.

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.

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.
