Double-sided solar panels .. Do they generate more electricity than single-sided?
Suitable for home projects with conditions
Two-sided solar panels have a higher capacity than conventional ones, with a rate of up to 27%, but they are not suitable for home generation except within a specific scope and certain conditions.
This came in an analytical report published by CNet, which indicated that the advantage of higher electricity generation from two-sided solar panels comes from the ability of the back face to generate energy, even if it is far from sunlight.
The report said that obtaining the full benefits of generating electricity using bifacial panels requires the availability of space behind them that allows sunlight to be reflected to reach the panel.
Although the availability of space behind the double panels helps them generate more electricity, they are not suitable for rooftops.
The idea of double-sided solar panels is similar to the phenomenon of snow reflecting light, as research has shown that ice reflects about 85% of sunlight, much more than what the surface of water reflects, which is only 7%.
The CNet report identifies several conditions to ensure the work of the back side of the board, in order to make full use of its duplication.
reflective elements
A Wood Mackenzie research report showed that the availability of reflective elements in the environment around a dual-panel solar power plant - such as the Australian desert sand - is one of the factors that contribute to greater and faster utilization.
It is also important to have spaces behind the double panels; This enables the back face to generate electricity, even when it is far from sunlight.
Previous data indicates that homes can benefit from two-sided solar panels, but provided that they are installed on the ground, and that there is space behind them.
And if the house that wants to benefit from the sun’s electricity generated through the double panels in an icy area, or sand reflecting sunlight, this will be better; It ensures efficient work of the panels.
clean electricity
The world is counting on solar energy as one of the main pillars of energy transformation, and reliance on clean and renewable electricity, but it has been witnessing continuous price hikes since last year.
The multi-fold increase in the prices of polysilicon - the main raw material used in the manufacture of solar energy equipment - is one of the main reasons for the rise in equipment costs for solar power plants.
