DAH solar panels incorporate the highest level of technology available at the moment, they are panels built from superior quality materials, rigorously tested, guaranteed 15 years.The primary forovoltaic cell is divided into two sections to prevent heating, to increase efficiency and to last better over time.PERC technology improves the capacity of the photovoltaic cell to capture electrons and the fact that they are manufactured on a monocrystalline structure means that they have the highest level of efficiency in generating electricity.A special element of these photovoltaic panels is the fact that they do not have a frame, so they are self-cleaning, dust and dirt will drain from the panel when it rains or when you sprinkle it with water, without this element meaning that they are less rigid than those with a frame.They are very resistant to transport and the weather, more efficient in producing energy in rainy weather than other panels. .All panels sold by us are quality A+++.
