Yes
Using only solar energy and without energy storage unit (battery) cannot guarantee 8 hours.
It must consist of the following parts:
1. Solar cell array
2. Battery bank
3. (220/380V is calculated according to the water pump voltage)
The cost is relatively high, and it is generally not recommended to use high-power AC water pumps.
Now that there is a water pump, we can analyze it. The water pump itself has an inductive load, and the configuration of the inverter is generally 5 to 8 times that of the inductive load
Then the inverter should be at least a 50 inverter KW
It depends on your day Power consumption: 10KW*8=80KWH
I don't know where you use it. Battery panel configuration should be related to local radiation conditions.
To keep things simple, let's assume that daylight hourslocal maximum is 5 hours (this value is very large, equivalent to the level of Xinjiang and Gansu)
Then, the battery must be at least 22 KWP or more. Based on current market price, the battery panel should be at least 33 WRMB.
The system voltage should be 300V or 600V
The inverter should be at least 15W and battery should be at least 400-500AH2V. 150 pieces must be at least 12WRMB
There are also brackets/bases/cables that cost at least 600,000-700,000 yuan. As for the battery panel area, find a model and calculate it yourself
