Flexible solar panels differ quite from rigid, rectangular, glass-encased standard solar panels typically found on rooftops. Rather, flexible solar panels come in all shapes and sizes and are expected to be used in a greater number of situations than standard panels Whereas portable solar panels contain solar cells mounted in a lightweight, often plastic frame and thin-film panels are made of materials like copper, selenium, and gallium, flexible and standard solar panels use solar wafers to convert sunlight to electricity. Most often, flexible panels use wafers made from silicon, though they are far thinner than those in standard panels-as thin as merely a few micrometers in width. Whereas standard panels are sandwiched between layers of glass, flexible panels are placed between layers of protective plastic. 

The solar hybrid AC/DC air conditioner can work without battery, it works with unstable solar panel DC power at day time. At night or rainy days it automatically get grid AC power. It's  mainly used for school classroom, hospital, restaurant, shops, office… With APP monitor and control function through WIFI

The on grid solar power system converts the solar energy into electrical energy, without the storage battery, and directly sends the electrical energy to the grid through the grid-connected inverter. Inverter power: 3kW AC output voltage: three phase Solar panel type: mono or poly
