lot of 10 MONO solar cells 3" x 6" 5BB 2.7 watts each laser cut grade-A

Description: LASER CUT beautiful smooth edges typical of laser cut cells. PERC solar cells 5BB ( buss bars) actual dimensions 6 1/4 x 3 1/8 ( 158 x 78 mm) bifacial cells : this means that the cell can actually pick up and convert the ambient light on the back of the cell into energy. 2.7 watts per cell.53 volts per cell5.09 amps per cell22% eff minimumthickness 190 um <> 20 um a 36 cell panel would be a 97.1 watt panel. 36 x .53 = 19.08 V x 5.09 Amps = 97.1 watts per panel. all cells rated using STC ( standard test conditions )STC stands for “Standard Test Conditions” and are the industry standard for the conditions under which a solar panel are tested. By using a fixed set of conditions, all solar panels can be more accurately compared and rated against each other. There are three standard test conditions which are:1. Temperature of the cell – 25°C. The temperature of the solar cell itself, not the temperature of the surrounding.2. Solar Irradiance – 1000 Watts per square meter. This number refers to the amount of light energy falling on a given area at a given time.3. Mass of the air – 1.5. This number is somewhat misleading as it refers to the amount of light that has to pass through Earth’s atmosphere before it can hit Earth’s surface, and has to do mostly with the angle of the sun relative to a reference point on the earth. This number is minimized when the sun is directly above as the light has to travel a minimum distance straight down, and increases as the sun goes farther from the reference point and has to go at an angle to hit the same spot.NOTE: in reality achieving the STC #'s is not possible , kinda like the EPA for gas mileage on cars, it is a benchmark for testing and comparison. No one but me will tell you about STC on a cell listing. so much will depend on your local conditions such as longitude,latitude, time of year, time of day ,sky conditions, airplane contrails ETC. ETC. PERC cell technology defines a solar cell architecture that differs from the standard cell architecture that has been in use for three decades and that is usually featured in all photovoltaic manuals.The objective of scientists being to get the most of electrons out of the solar cells, the PERC architecture essentially enables to improve light capture near the rear surface and to optimize electrons capture. Bottom line: a bit of production is gained from light reflecting on the back of the cell. Unheard of years ago.
