LiFePo4 Bettery(WH) = Lamp Rated Power * Full Power time / DOD(85%) * Consecutive days


DOD(Depth of Discharge): Starting to discharge at the upper limit voltage of the battery and end when the lower limit voltage is reached.

We define all the discharged electricity as 100% DOD in this process. And 85% DOD means to release 85% of the power.

For the same battery, the DOD is inversely proportional to the battery cycle life.

In the case of DOD 85%, the lithium battery has a cycle life of up to 1500 times and a service life of 5 years.


Consecutive days = Rainy backup days + One working night before rainy day


Solar Panel(W) = Lamp Rated Power * Full Power time * System Energy Loss * Battery back up power/ Local peak hour

System Energy Loss: The typical energy loss in the dust and cable connection

Battery backup power: 20%

Local peak hour: in case of 4.5h
