Are double-sided solar panels cost efficient?

A new paper analyzes the cost efficiency of different double-sided solar panels. Solar researchers keep finding new ways to scrub energy out of less-than-ideal sunlight situations— even nighttime. The research found that single axis tilt is still the best combination of energy efficiency and cost.

How do double sided solar panels work?

Double sided solar panels which collect light on both sides and move to follow the sun’s position produce over a third more energy than standard systems. Most solar panels installed around the world are fixed in one position, without the ability to adapt to where the sun is in the sky.

What is a double sided solar cell?

The double-sided solar modules can be divided into P-type double-sided and N-type double-sided according to the different crystal silicon substrates. At present, the mass-produced double-sided solar cell structure is mainly composed of P-type PERC double-sided, N-PERT double-sided and HIT.

Can double-sided solar panels track the Sun?

Researchers have looked at the benefits of combining solar panels that track the sun with double-sided solar panel arrays for the first time. This article is more than 2 years old.

Are double-sided solar panels better than single-axis trackers?

The model suggests that double-sided solar panels combined with single-axis tracking technology is most cost effective almost anywhere on the planet, although dual-axis trackers -- which follow the sun's path even more accurately but are more expensive than single-axis trackers -- are a more favorable substitute in latitudes near the poles.

What are the benefits of two-sided solar panels?

Double-sided solar panels can absorb energy from both sides: they absorb energy directly from the sun and also from the reflected energy off the ground on their rear side. The goal for any solar panel is to absorb as much energy from the sun as possible, and this design allows for an additional energy source.
