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 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: 5kW AC output voltage: single phase 220V Solar panel type: mono or poly

The 60kw off grid solar system is suitable for area without grid or grid is not stable. It can be compatible with generator or grid. Inverter power: 60kw power frequency  inverter AC output voltage: AC120V/240V split phase or three phase 208V/380V Battery voltage: DC360V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly

The solar energy storage inverter can be used for both on grid and off grid solar systems, it integrates controller and inverter. During the daytime, the PV array generates electricity to provide power either to the loads, or  to the grid or charge the battery.  The battery can be charged either by PV power or by grid, the power stored in the battery can be released whenever the loads require it.  Moreover ,the inverter can give three phase unbalanced output accroding to set up, to make a most flexible power solution.
