Consumption 3KW
To sell 2KW
Consumption 1.5KW
Charging
1.5KW
To buy 3KW
The rest generated power after consumption will be sold to
the grid, and the stored electricity can be used at evening
Day time
The electricity bought from the grid will be supplied for
consumption, and the rest can be stored in to the battery
Night time
Normal mode
This mode is usually applied in the regions with big difference of electrical bill between day and night.
The priority is to sell the power at high price, while store it at low price, which brings profit to the users

Operational mode
The rest generated power after consumption will be firstly
stored into the battery, then sold to the grid if still remains
Day time
The electricity stored in battery will be mostly supplied for
consumption. It could be taken from the grid if not enough
Night time
Economical mode
This mode is usually applied in the regions with high electrical bill, but without big difference between
day and night. The priority is to maximize the self consumption of solar power as much as possible

for consumption, and the rest can be stored into the battery
Day time
The electricity stored in the battery will be all supplied for
consumption, which is the only power source at the moment
Night time
Storage mode
This mode is applied as a backup plan when power outage or fire accidents occur. The solar power
stored in the battery would help the users continuously keep using electricity even during the night

There are two sorts of BIPV applications: one is solar heat, and another is photovoltaic. The former is to provide us hot
water and air condition from solar radiation, and the latter is to provide us illumination from the solar energy, which can
only be partially converted into electricity (about 16%), and the rest (about 84%) could be totally converted into heat.
