Higher energy yield solar bifacial photovoltaic panels

Maximize your energy output with our advanced Bifacial Solar Panels—the perfect solution for solar lighting systems and large-scale energy generation alike. These rigid solar panels utilize both the direct sunlight captured on the front and the reflected sunlight on the back, offering significantly higher energy yields. Designed to get energy from multiple light sources, including ground reflections and neighboring PV modules, these bifacial solar modules deliver up to 30% more energy than traditional panels.
The photovoltaic module for solar panels operates just like a conventional panel on the front side, but the real innovation lies in the rear side, where it captures reflected and diffused light. This unique design enables it to produce more energy in a compact form—meaning a 480W bifacial panel can deliver the same output as two 300W panels. Not only does this save you space, but it also offers excellent cost-effectiveness.
While bifacial solar panels are a bit more expensive than their standard counterparts, they prove to be a smart investment in the long run. Under optimal conditions, they provide a greater energy yield with less installation space required, making them ideal for applications like solar generators and lamp solar lights.

To ensure that the solar panel can absorb the most energy for charging, we recommend installing it in a location with the longest sunshine hours and the most sunlight. The specific installation location needs to be selected based on your project.

Here are some suggestions for solar panel installation:

• Orientation selection: Best suited for installation in the south-facing direction. Installation in a west- or east-facing direction may result in reduced lighting hours. It is not recommended to install in the north direction.
• Height setting: Installing in a higher position can reduce the obstruction of ground objects (such as vehicles, plants, etc.) and maximize the use of sunlight.
• Avoid blocking: When installing, make sure there are no tall buildings or trees around the solar panels that block the sun during the day.
• Angle adjustment: During installation, the tilt angle of the solar panel needs to be adjusted so that it faces the sun and is as perpendicular to the sun as possible to improve absorption efficiency. The ideal angle is approximately the angle of the local latitude.
  

Although the initial investment of solar energy is relatively high, its advantages include long-term low operating costs, savings in electricity bills, simple installation process, and less manual maintenance.
