Bifacial solar panels: higher energy production with efficient structures

The evolution of photovoltaic technology is advancing rapidly, and one of the most interesting innovations in recent years is bifacial solar panels. This type of module allows electricity to be generated from sunlight on both the front and the rear side, increasing the overall performance of the installation.

At e-cobert, we design robust and modular steel structures that allow solar installations to take full advantage of this technology.

What are bifacial solar panels

Bifacial solar panels are photovoltaic modules designed with solar cells visible on both sides.

Unlike traditional panels — which only produce energy from the front side — bifacial panels capture:

Direct solar radiation on the front side
Reflected light from the ground or nearby surfaces on the rear side

This phenomenon increases the total energy production of the installation. Under optimal conditions, bifacial panels can generate between 5% and 30% more energy than conventional panels.

Why structures are key in a bifacial installation

The performance of bifacial panels depends largely on how they are installed and on the structure that supports them.

Some important factors include:

Height of the panel above the ground, allowing reflected light to reach the rear side.
Spacing between modules, reducing shading and improving solar gain.
Reflective ground surfaces (light gravel, concrete, sand or white roofs).
Proper orientation and tilt angle to maximize solar capture.

For this reason, a well-designed structure is essential to achieve the maximum performance from this type of panel.

e-cobert structures for bifacial solar panels

e-cobert steel structures are designed with functionality, structural strength and easy installation in mind.

Thanks to their modular system they allow:

Installation of bifacial solar panels with the correct height and tilt.
Creation of solar pergolas, solar carports or technical roof structures.
High structural rigidity and resistance to wind and weather conditions.
Easy transport and installation thanks to a modular palletized format.

These structures help maximize the potential of bifacial panels, especially in industrial installations, solar parking structures or roofs with open space beneath the modules.

A technology with a strong future in solar energy

Bifacial technology is becoming one of the main trends in the photovoltaic sector because it allows higher energy production without increasing the installation footprint.

This makes it a very attractive solution for:

industrial installations
solar parking structures
technical roofs
photovoltaic pergolas

When combined with a robust and well-designed structure, this technology helps optimize energy performance and improve the profitability of solar projects.
