The time has come for roofs to provide more than shelter. So we challenged the very definition of what a roof is,
our latest Save Green solar roof tiles, is a revolution in roofing history.
It's a perfect combination of photovoltaic solar module and stone slate.
Features
Save Green roof tile integrates 12 monocrystalline silicon solar cells. The cells are embedded within slate frame. Installed on unshaded pitched roof, It makes full use of roof to provide seamless clean electricity in decades.
There are two options to install it, on-grid and off-grid systems. On-grid system has more than 70% conversion rate, whereas off-grid with battery in charge promises 17% - 25% conversion depending upon light intensity.
The other components of save green roof tiles include invertor, controller (cluster) and battery.
The monocrystalline silicon solar cell achieves Grade A class.

Application
Off-grid mode is widely used in mountain area where no electricity is provided, buildings that require energy saving and environment protection, and areas that need lighting.
In-grid mode is offen seen in North America and Europe. In countries where in-grid system is supported, the end-users of solar products are allowed to sell electricity back to local electricity company.
