Castries bifacial solar panels recommended

Bifacial solar panels can be effective when installed on elevated structures such as solar carports, canopies and pergolas. Elevation allows more sunlight to reflect off surrounding surfaces and reach the underside of these panels, increasing energy production.

Ideally, bifacial panels should be aligned to ensure maximum sunlight exposure on both sides throughout the day. Plus, the tilt angle should be optimized based on the local latitude to maximize solar radiation capture. Bifacial solar panels are more sensitive to shading on either side.

Installing bifacial panels on solar carports increases energy production without using additional land. The rear side captures reflected light from cars, pavement, or white-painted surfaces. Initial Costs: Bifacial solar panels can cost up to 10% more than monofacial panels due to their advanced manufacturing and materials.

Monofacial solar panels use an opaque backsheet that only permits the front face of the panel to receive sunlight. Conversely, Bifacial solar features light-absorbing panels exposed on both sides. This enables them to absorb reflected light from surfaces such as white rooftops, sand, or snow.

Minimum Height Above Ground: Generally speaking, the higher the bifacial solar panels are installed above the ground, the more pronounced the gain effect from the back side. However, when the height exceeds 1.3 meters, the increase in irradiance received by the back side begins to plateau.

One round of operation ends for a monofacial panel after the incident light strikes the front side of the panel and is absorbed and converted into electricity. For a bifacial solar panel, in addition for front-side conversion, part of the direct light would pass through the panel and be reflected back to the rear side by the surface below.
