Bauer 450W Bifacial
DC Capacity: 450W
Model: BS-144M6HBB-GG
Height: 83.54"
Width: 41.25"
Efficiency: 20.24% The efficiency of the photovoltaic (PV) cells that make up a solar panel is calculated on the basis of energy from sunlight that is converted into electricity by semiconductors. An efficient solar panel is one that generates more electricity by occupying less space. Manufacturers rate solar panels by their efficiency, which ranges from around 15% to 22% of conversion of the sun's energy transformed into usable electricity.
Product Warranty: 30 Years The product warranty replaces your solar panels for free if they malfunction due to material or workmanship defects.
Power Warranty: 30 Years Power warranties are also known as performance warranties. Photovoltaic (PV) cells gradually lose performance, and this means the amount of electricity generated will decrease slightly each year. However, a power warranty ensures that this will happen at a very slow rate. Solar panel manufacturers specify a maximum degradation rate, and the power warranty covers you if they deteriorate faster. For example, if your manufacturer specifies a performance loss of 0.50% per year, and your solar panels start to lose 1% of their productivity per year, the performance guarantee comes into effect, and you get a replacement.
Degradation Rate: 0.5% Solar panels slowly degrade over time, meaning that they produce less electricity from the same amount of sunlight. The causes of solar panel efficiency degradation include wear and tear due to weather. The average productive life of solar panels is 30 years. According to the National Renewable Energy Laboratory (NREL), solar panels and their output degrade at a rate of about 0.5% per year: a 20-year-old panel will produce approximately 90% of the electricity it produced in its first year of life.
