Disadvantages of double-sided glass photovoltaics
Dual-glass type modules (also called double glass or glass-glass) are made up of two glass surfaces, on the front and on the rear with a thickness of 2.0 mm each.
This traditional design focuses only on capturing sunlight from the front. Solardeland bifacial double glass panels are designed to capture sunlight from both sides. They are enclosed between two layers of tempered glass, allowing the back to absorb reflected light from the surrounding surfaces.
They can be heavier if the manufacturer has used thicker glass (e.g. 2mm). Our panels with 1.6mm front and back weigh in at 21kg, which is comparable to single glass. (But thicker glass can be a very good thing). They used to be more expensive – but the price gap has really decreased in recent years.
There has been a noteable shift from the initial single-facial single-glass modules to bifacial double-glass modules. Double-glass modules, with their performance in the face of salt mist, high temperatures and high humidity, have won the market's favour. However, this trend is not without its risks.
They are enclosed between two layers of tempered glass, allowing the back to absorb reflected light from the surrounding surfaces. The double-glazed design gives them a transparent or translucent appearance, which is different from the opaque single-sided panels.
