Recently, solar panels are increasingly used as renewable energy sources. They have many advantages over other energy systems: they are not machines and have no rotating parts, they require minimal maintenance, they work better at low temperatures, including negative ones.
The company produces solar panels with high efficiency and reliability. They are made of quality materials and have stable performance. The company holds over 200 patents. Their solar panels are manufactured in 4 factories in China.
They have a high conversion efficiency compared to conventional polycrystalline photovoltaics. This means they can produce more electricity per square metre, making them an efficient choice for sites with limited roof space.
Monocrystalline silicon is a high-quality material known for its durability and longevity. DAH solar panels are designed to withstand harsh weather conditions and are built to last for decades.
This product meets the conditions for financing solar systems according to BG-RRP-3.006 "Construction of new RES for own consumption in combination with local energy storage facilities in enterprises".
Each of the panels has an initial power that is between 0 and 5Wp higher than the nominal. This guarantees you a higher energy yield over the years.
For this type of application, we offer another type of panels. Please, check: https://shop.chepakov.com/en/solar-panels/solar-panels-for-caravans-campers .
