Single crystal single glass solar panel

What is a mono glass solar panel?

Mono-glass (single-glass) solar panels use tempered glass on the front and a polymer backsheet on the rear. This design is reliable and widely used in most homes. Glass-glass (double-glass) panels use glass on both sides. Many are bifacial, meaning they can collect sunlight from the back too. This design can boost energy on reflective surfaces.

What is the difference between mono-glass and glass-glass panels?

Mono-glass panels cost 10–20% less upfront. They are lighter, faster to install, and easier to maintain. Glass-glass panels cost more. Bifacial models and extra glass add to production, shipping, and labor costs. Still, for big, sunny, reflective sites, glass-glass can recover the higher cost with extra generation.

How long do solar panels last?

Glass-glass panels add rigidity and better defense against moisture, salt mist, and sand. Some use silicon heterojunction (SHJ) cells with bifaciality over 90%. These solar panels, especially with glass-glass design, can last 30+ years. Mono-glass panels cost 10–20% less upfront. They are lighter, faster to install, and easier to maintain.

How much does a bifacial solar panel weigh?

Glass-glass panels often weigh more. However, modern thin-glass versions — around 21 kg (~46 lb) — are coming onto the market. Also, bifacial (glass-glass) panels average slightly heavier — about 53 lb vs 48.5 lb for monofacial. Lighter solar panels are easier to ship, easier to mount, and put less stress on the structure.
