In this article, we will learn about load calculation. If you are looking for a solar solution, then you must know how to calculate the total load of your home or workplace.
Through load calculation, you will be able to analyze the solar plant capacity you need to install to meet your energy demands.
Step 1: Make a list of electrical equipment:
The first step is to list all your household electrical appliances accurately. For this, you can follow the table. List every appliance individually to understand the power consumption.
| Electrical Appliance | Power Rating (Watt) | Run Time (Hour) | Total Consumption (Watt/Hour) |
|---|---|---|---|
| A1 | |||
| A2 | |||
| A3 | |||
| C1 | |||
| C2 | |||
| C3 |
Load Calculation
- The sheet has 4 columns, the first one is the appliance.
- The second one is the power rating of the appliance, which means, how much power that appliance consumes in 1 hour.
- The third column is of total running time in hours, which means how long the appliance has been running in a 24-hour time cycle.
- The last column is of total power consumption which can be calculated by multiplying the 2nd and 3rd columns.
For example, if you have 3 fans each with a 50-watt rating, that run for 10 hours in a day. Then your power consumption would be 3*50*10= 1500Wh
Step 2: Accommodate the power Losses
Add the 4th column and multiply it by 1.25 to accommodate the power losses. In every electrical device, there is some loss of power during transmission which gets converted into heat. As a result, there is a difference between the input and the output of a device.
| Appliance | Power Rating (Watt) | Run time (Hour) | Total Consumption
(Wh) |
|---|---|---|---|
| 3 Lights | 15W (each) | 9 | 3*15*9= 405 |
| 1 Fridge | 500W | 24 | 500*24=12,000 |
| 1 Tv | 70W | 4 | 70*4=280 |
| 3 Fans | 40W (each) | 10 | 3*40*10=1200 |
| Total | 13,885 |
Total per day consumption: 13,885*1.25= 14,185Wh or 14.18kW.
This means that in a single day, you consume around 14.18 units which roughly translates to 425 units in a month.
Now, this final data will tell you what is your total power consumption & accordingly, you can look for solar solutions and government benefits.
