The efficiency of solar photovoltaic modules is efficient, with radiation-related efficiency, solar photovoltaic module arrays, aluminum nano-cylinders, and other types of efficiency. So what is the efficiency of solar photovoltaic modules, let us take a look at it next.

Here is the content list:

  • Radiation related efficiency

  • Solar photovoltaic module array

  • Aluminum Nano Cylinder

Radiation related efficiency

Depending on the structure of solar photovoltaic modules, solar photovoltaic modules can generate electricity from a series of frequencies of light, but usually solar photovoltaic modules cannot cover the entire solar radiation range (especially ultraviolet, infrared, and low light or diffuse light). Therefore, most of the incident sunlight energy is wasted by solar photovoltaic modules. If irradiated with monochromatic light, solar photovoltaic modules can provide higher efficiency. Therefore, another design concept is to divide the light into six to eight different wavelength ranges to produce different colors of light and direct the beam to different cells tuned to these ranges.

Solar photovoltaic module array

A single solar photovoltaic module can only generate a limited amount of electricity; most installations contain multiple solar photovoltaic modules, adding voltage or current to the wiring and solar photovoltaic module system. Photovoltaic systems usually include solar photovoltaic module arrays, inverters, battery packs for energy storage, charge controllers, interconnect lines, circuit breakers, fuses, circuit breakers, voltmeters, and optional solar tracking mechanisms. Solar photovoltaic module equipment has been carefully selected to optimize output, energy storage, reduce power loss during power transmission, and conversion from DC to AC.

Aluminum Nano Cylinder

Studies have shown that inlaying aluminum nano-cylinders on the surface of light-receiving semiconductors through solar photovoltaic modules can improve the efficiency of solar photovoltaic modules. This scattered light then travels along a longer path in the semiconductor, absorbing more photons and converting them into electric current. Although these nano-cylinders have been used previously, light scattering occurs in the near-infrared region, and visible light is strongly absorbed. It is found that aluminum absorbs the ultraviolet part of the spectrum, while the visible and near-infrared part of the spectrum is found to be scattered by the aluminum surface. Research believes that this can significantly reduce costs and improve efficiency because aluminum is more abundant and less expensive than gold and silver. The study also pointed out that the increase in solar photovoltaic module current makes thinner solar photovoltaic modules technically feasible without "influencing power conversion efficiency, thereby reducing material consumption."

The efficiency of solar photovoltaic modules can be calculated by the MPP value of solar photovoltaic modules.

The solar photovoltaic module inverter converts DC power to AC power by performing the maximum power point tracking process. The solar inverter samples the output power of the solar photovoltaic module and applies appropriate resistance to the solar photovoltaic module to obtain the maximum power.

The MPP (Maximum power point) of a solar photovoltaic module is composed of MPP voltage (VMPP) and MPP current: it is the capacity of the solar photovoltaic module. The higher the value, the higher the MPP.

Micro-inverter solar photovoltaic modules are connected in parallel to produce more output than ordinary solar photovoltaic modules connected in series. The output of the series is determined by the solar photovoltaic module with the lowest performance. This is called the "Christmas Light Effect". Micro-inverters work independently so that each solar photovoltaic module can contribute its maximum possible output for a given amount of sunlight.
