In recent years, with the continuous advancement of solar energy technology and the surging demand for green energy, more customers have begun focusing on how to ensure the stable operation of solar systems under harsh weather conditions. Addressing this critical concern, the SUNFREE team, after extensive R&D and rigorous testing, has launched an innovative vertical solar module. Today, we ...

With the continuous popularization of the global low-carbon and environmental protection concept, solar energy technology is changing our lives at an unprecedented rate.

Against the backdrop of global energy transition and green development, solar energy, as a crucial component of clean energy, is gradually replacing traditional fossil fuels to provide sustainable power for various industries.

In recent years, lawn lights in residential areas have gradually taken on a new form—appearing as minimalist art installations during the day and automatically emitting soft light at night. These devices, which require no wiring and zero electricity costs, achieve energy self-sufficiency through solar panels integrated into their body. 

Under the global trend of energy transition, solar streetlights are gradually replacing traditional grid-powered lighting, becoming a critical component of smart city development. However, as technology advances, how to make solar streetlights smarter, more efficient, and reliable has become a key concern for urban managers and project contractors. The emergence of D4i technology is providing i...

In high-latitude areas with low solar angles and long, harsh winters, energy supply has long been a critical challenge for residents and businesses. In recent years, driven by growing environmental awareness and technological innovation, a new type of vertical solar tube has emerged, offering a groundbreaking solution to energy shortages in these regions.

As global attention to renewable energy increases, solar energy, as a clean and renewable source, is gradually becoming a part of our daily lives. Especially in the field of lighting, the application of solar streetlights and solar lamps is transforming the landscapes of both urban and rural areas with their eco-friendly and efficient characteristics.

The city’s nights are illuminated by streetlights, but few realize that these streetlight poles themselves can become energy producers.

⭐ About PERC Technology　PERC ((Passivated Emitter and Rear Cell))PERC stands for Passivated Emitter and Rear Cell. The PERC solar cell has a presence of a passivation layer at the back side of the cell, which helps to minimize recombination losses and increase light absorption. The key role of the rear-side passivation layer is to reflect light that passes through the silicon cell without being...

There is a wide range of energy storage options when it comes to the stationary power market. Some of these include compressed air, capacitors, flywheels, rechargeable batteries, and compressed air. These different energy storage options have their own advantages, each depending on their use and application. Below, we are going to compare two different battery chemistries: lithium-ion and lead ...
