Among them, we focus on the product agency of Sakomicro for general semiconductors; prioritize Rubycon brand for electrolytic capacitors; and take TDK as the core supplier for chip capacitors. Meanwhile, we provide distribution services for products of other well-known brands, offering a one-stop solution to meet diverse procurement needs.

 

 

SOLAR POWER SYSTEM

 

Backed by professional expertise and extensive experience, we accurately cater to customer requirements and provide custom-tailored exclusive solutions. Our business scope includes the customized production of various photovoltaic panels and inverters, as well as one-stop equipment installation engineering services within Guangdong Province.

As one of the "Four New Pillars" of new energy, photovoltaic (PV) panels are the core components of photovoltaic power generation systems, enabling the direct conversion of sunlight into electricity. Their core working principle is as follows: After semiconductor materials (e.g., silicon) inside the panels absorb the energy of photons from sunlight, they excite the internal electrons to produce directional movement, thereby forming an electric current. Finally, the electrical energy is stably output through the circuit. Currently, the mass-produced and applied photovoltaic panels are mainly categorized into the following four types:

 

 

Monocrystalline Silicon Solar Panel

This type of photovoltaic (PV) panel boasts the highest market share and the most mature technology, with an ultra-long service life of 35 years and excellent operational stability. It has a conversion efficiency of 18%-24%, and adopts glass lamination and aluminum alloy frames for enhanced protection. It is suitable for mainstream application scenarios such as residential rooftops and high-efficiency photovoltaic power plants, while its only drawback is the relatively high unit price.

 

 

Polycrystalline Silicon Solar Panel

This photovoltaic (PV) panel features mature and reliable technology and boasts the distinct advantage of cost-effectiveness, with an extended service life of 30 years and a photovoltaic conversion efficiency of up to 18%-20%. It adopts a dual-protection structure consisting of glass lamination and aluminum alloy frames, delivering excellent mechanical strength and weather resistance. The product is widely suitable for large-scale grid-connected power generation projects in large photovoltaic power plants.

 

 

Amorphous Silicon Solar Panel

As a typical representative of thin-film photovoltaic (PV) panels, this product uses amorphous silicon (a-Si) with an amorphous structure as the core light-absorbing layer, which forms a distinct contrast with the crystalline structures of monocrystalline and polycrystalline silicon. With prominent characteristics such as flexibility and bendability, excellent low-light response, and cost-effectiveness, it has irreplaceable application advantages in scenarios like Building-Integrated Photovoltaics (BIPV) and portable photovoltaic devices, with a photovoltaic conversion efficiency of approximately 10%-12%.

 

 

Perovskite Solar Panels

A new generation of high-efficiency and low-cost photovoltaic technologyperovskite photovoltaicshas burst onto the scene! Its core light-absorbing layer adopts innovative perovskite-structured materials, and when stacked with silicon, the conversion efficiency soars to 28%. At this stage, it focuses on small-size and low-light power generation scenarios. Leveraging its unique advantages such as rapid efficiency improvement, affordable manufacturing costs, and flexibility with customizability, it has quickly emerged as a hot topic in the R&D and industrialization of the photovoltaic sector.

 

 

Inverter

As the "energy conversion hub" of photovoltaic power generation systems, inverters assume the crucial mission of converting direct current (DC) from photovoltaic panels into usable alternating current (AC), ensuring smooth grid connection or direct power supply to loads. They offer a diverse range of product types, covering three major categories: off-grid inverters (stand-alone inverters), grid-tied inverters, and energy storage inverters (hybrid inverters), fully adapting to different photovoltaic application scenarios.
