Till now, we have learnt the basics of the solar electricity, here in this post we will learn to design the solar system by ourselves.
As you know that the basic components of the system are:
The step by step procedure of designing the system as follows:
(1) Determine the Power consumption demand
Let us take an example, in a house there are:
This is the daily energy requirement that needs to be backed by the solar panels.
(2) Sizing the PV panels
Therefore, number of 100 watt panels needed: 378/100= 3.78 or at least 4 numbers
(3) Inverter sizing
The total watt of the appliances is
(For safety purposes the inverter should be at least 25%-30% bigger in size)
(4) Sizing the batteries
Now let us suppose that backup required from the batteries is 5 hours.
(5) Sizing the solar charge controller
So, the solar charge controller should be rated 33.02 amperes at 12 volts or greater.
This is the basic designing that one can do oneself and evaluate the cost of the system based on the specification of the components.
