Fangxing eco-friendly solar photovoltaic(PV) roof slate, Duer, use
12 pieces of monocrystalline silicon solar cells in each solar
panel, which is embedded in slate support structure. Installed on
unshaded sloping roof area, Duer make full use of roof to provide
seamless electricity in decades.
Duer is a revolution in solar roofing history. It's a perfect
combination of photovoltaic solar tile and natural stone slate tile. There are two options for building to integrate Duer to roof,
on-grid and off-grid systems. The off-grid system is a stand-alone
solar roofing system, ideal for home and business building that
can't connect to country grid, the stable converted solar power can
meet the needs of daily house electricity request. On the other
hand, the on-grid module enable house owners to sell extra solar
power to grid companies besides daily electricity usage.
Duer solar roof system has four components: solar panel, inverter,
battery and charge controler. The current is created by solar
energy (sun light) in embedded solar panel, then power saved in
battery after going through controler. The charge controler and
inverter will adjust the demand by end user so as to smoothly
output enough electricity.
The house roof powered by Duer solar slate can minimize household
electric bill and offer substantial returns on investment. It's
- stable electricity supply
- zero noise
- easy and flexible installation
The conversion rate of Duer is about 15%-17%. We guarantee 20 years
80% output in regard to quality. After months of lab tests, Duer is
proudly certified by TUV and safe for residential, commercial and
industrial buildings around the world.
