Photovoltaic inverter power board coating

Is there an anti-soiling coating for solar PV modules?

Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that are at least two years old. The new product is claimed to increase power yield by up to 7% and to have a payback time of 2.5 to four years depending on the dust level of the site.

What is a photovoltaic (PV) panel?

The solar panel or PhotoVoltaic (PV) panel, as it is more commonly called, is a DC source with a non-linear V vs I characteristics. A variety of power topologies are used to condition power from the PV source so that it can be used in variety of applications such as to feed power into the grid (PV inverter) and charge batteries.

What is a micro-inverter in PV?

There is also growing interest in the PV industry to use micro-inverters. These inverters are placed on every module such that the voltage of each module is optimized to the maximum power voltage, 168 in the range of 30 V to 40 V for conventional c-Si PV modules.

What are AR coatings on photovoltaic panels?

AR coatings on the front side glass of photovoltaic (PV) panels were first introduced at commercial scale in 2012. Today, their technology is state-of-the-art, boosting the PV panel’s yield by 3-4%.

What are SiC-based devices used to improve PV inverter performance?

Recently, silicon carbide (SiC)-based devices are used to improve the performance of PV inverters . The prices of SiC diode and metal–oxide–semiconductor field-effect transistor (MOSFETs) decrease by 10% per year. These SiC devices are replacing Si devices for PV inverter applications.

What are the challenges of SiC-based PV inverter?

However, the SiC-based PV inverter is challenged by many issues, as shown in Fig. 12. Due to the very fast switching speed, high dv / dt, and di / dt, the employed SiC devices cause serious ringing, cross-talk, etc. These issues are discussed in detail as follows. Fig. 12.
