For estimating the solar power system requirement it depends on mainly following factor
- Your power consumption.
- Sun light peak value.
- Your power storing device.
- How much energy can a Solar panel generate over a period of time?
there are many walls solar panel is available lets take one example
The power generation rating of a Solar panel is also given in Watts (eg STP010, 10W). To calculate the energy it can supply to the battery, multiply Watts by the hours exposed to sunshine, then multiply the result by 0.85 (this factor allows for natural system losses).
For the Solar 100W panel in 4 hours* of sunshine,
100 x 4 x 0.85 = 340WH. This is the amount of energy the Solar panel can supply to the battery.
As your requirement is 600000 so per day is 20000
So according to your requirement 20 kwh per day so you need
and for easy calculation i found one site Calculate Estimate of solar power system
Here is a list of the PV system basics:
2. Mounting equipment
3. DC-to-AC inverters
4. Tracking mounts
5. Disconnect switches
6. Wiring and fuse box connections
7. Utility power meters
For more information you should contacts to solar system service provider.
As your electical power usually needs to be available when the sun is not shining, it usually neccessary to store electricity.
Now a days there are many types of batteries and generator are available which stores the electricity produced by solar panel.
The normal storage is the Lead-Acid battery.
