With high-efficiency monocrystalline silicon cells, this 15W solar panel offers a maximum power output of 15W. It operates at a voltage of 18V and has an open circuit voltage (voc) of 21.6V, with a maximum power current (impp) of 0.83A. The innovative design includes transparent dots on the surface, which gather sunlight from various angles and enhance the solar conversion rate. These matrix-distributed dots cause refraction, utilizing sunlight twice and further boosting the panel's efficiency. MC4 output connector is compatible with RVs, yachts, 12V car batteries, balconies, and roofs.
Q1. What is the lifespan of 15W solar panel?
Flexible solar panels have a long service lifespan, 15W flexible PV panel typically has a lifespan of closer to 15 to 20 years. However, the amount of time a solar panel can make back its cost by saving on electricity is much less than its lifespan.
Q2. Is the 15W flexible solar panel too hot?
Due to their direct mounting on the surface, flexible panels lack an air gap to facilitate cooling. During periods of high temperatures, the panels can reach elevated temperatures, which can result in a reduction in power output. In extreme high temperature environments, this can result in a 20% loss of rated output power.
