Solartech Power's SPM220P-N 220 Watt, 24 Volt Polycrystalline solar panels are made from silicon wafers cut from multi-crystal silicon (they are also known as multicrystalline panels) and are also more efficient than amorphous panels. Polycrystalline panels are excellent for all small solar applications like RV's and 4WD's. Larger polycrystalline modules are also suitable for domestic and business solar installations.
These Polycrystalline modules come in 24 volts to cater for 24V power systems. They can be linked in parallel to maintain a 24V system or can be linked in series to create a higher voltage system. These modules have proven performance at high temperatures and generally feature a robust design makes the product durable in the field and easy to install.
Solartech Power advanced cell processing technology and automated production facilities produce a highly efficient multicrystal photovoltaic modules. These cells are encapsulated between a 3.2 (mm) tempered glass cover and a pottant with back sheet to provide efficient protection from the severest environmental conditions. The entire laminate is installed in an anodized aluminum frame to provide structural strength and ease of installation.
A polycrystalline solar panel is made from a block of silicon that has multiple crystals. These panels are square in shape, and may have a surface that looks somewhat like a mosaic due to all of the different crystals that make up the panel. Other types of panels may appear smooth and even, because they are made up of only silicon crystals, whereas the Polycrystalline looks fragmented and angular. The lifespan of a polycrystalline cell is a minimum of twenty-five years and can be more than fifty, making them a worthwhile investment for long term use.
