The Guyana, Power & Light offers rebates (compensation) for any excess energy produced by solar systems attached to the national grid. How does solar energy impact the environment compared to traditional energy sources? Solar energy produces no greenhouse gas emissions during operation, unlike fossil fuels. What is the cost for a backup system?
Glass-Glass module designs are an old technology that utilises a glass layer on the back of modules in place of traditional polymer backsheets. They were heavy and expensive allowing for the lighter polymer backsheets to gain the majority of the market share at the time.
The weight of glass-glass modules are still an issue, with current designs using 2 mm thick glass on each side for framed modules, the weight is about 22 kg, while 2.5 mm on each side will increase the module’s weight to 23 kg. Compared to traditional glass-foil modules, which are about 18 kg, this is a 20% increase in weight.
Despite the challenges of the glass-glass modules design, the increased reliability, subsequent 30 year warranty and transparent back enabled bifacial technology to exist.
Therefore. over a 30 year lifetime it can be expected to still operate at 85% of the nameplate capacity. The weight of glass-glass modules are still an issue, with current designs using 2 mm thick glass on each side for framed modules, the weight is about 22 kg, while 2.5 mm on each side will increase the module’s weight to 23 kg.
Compared to traditional glass-foil modules, which are about 18 kg, this is a 20% increase in weight. Although there is no standard on glass thickness, in general it is a more complex and expensive process to produce very thin, tempered glass. However, 2.5 mm glass thickness does allow for frameless designs, which can reduce costs dramatically.
