China’s ZNSHINE develops solar noise filter to increase PV power output by 30%

China module manufacturer ZNSHINE SOLAR will bring noise reduction tech to Europe next year to capture energy loss and lower PV power costs

The solar noise filter is expected to increase PV power performance and cut costs

Chinese mono-and polycrystalline module manufacturer ZNSHINE SOLAR has developed cost-effective solar noise reduction technology which can increase PV power plant output by up to 30 per cent. The solar noise filter, called Pulse technology, has been ten years in the making. It captures energy loss in PV power plants and increases PV outputs, which reduces the costs of solar power generation.

The patented solar noise filter has been invented and developed by ZNSHINE SOLAR’s Toru Kinjoh.

Kinjoh said: “We have been developing this technology for more than ten years. The noise appearing in the power transmission process has always been an issue in the industry. By reducing the noise we are able to increase the power plant output by up-to 30 per cent.”

ZNSHINE SOLAR´s CEO William Wang, added: “ZNSHINE SOLAR has always been committed to researching innovative solutions to drive down the costs of power generation. We are glad to be able to offer our customers such a breakthrough solution, which increases by far the plant´s outputs, maximising returns on the investment and driving down the cost of kWh generation. This technology is another solid argument demonstrating that the sun is the energy of the future.”

Improving PV power performance  

Solar power systems are prone to energy loss because of electromagnetic phenomena – commonly known as noise – such as those caused by the internal resistance of solar cells and transmission channels.

The solar noise filter reduces the noise within the PV power system, but also increases the system´s performances. The solar noise filter is an electron accelerator working by a magnetic field, which is generated by self-exciting methods. This accelerates and structures the movement of the electrons, making the circuit work like a superconductor. Applied between modules and the inverter, the solar noise filter reduces the noise at solar cell, module and plant level, improving the energy transmission within the system. This reduces module operating temperatures, which further improves the module efficiency. At its full potential, the Pulse Technology can reduce module operating temperatures by up to 15°.

ZNSHINE SOLAR will be the exclusive supplier of the solar noise filter in Europe. The technology will be commercially available by summer 2014.
