How to Choose the Right Solar system for Your Home in Erode

When planning a solar panel installation in Erode, many homeowners make one common mistake — they calculate solar system size only based on the total load of appliances at home. For example, if a customer has 2 air conditioners, 3 water heaters, 1 mixie, 15 lights, and 5 fans, they often assume that all these appliances will run together and plan their solar system accordingly.

However, in real life, this doesn’t happen. Not all appliances operate at the same time, and this wrong assumption can lead to oversized or undersized solar systems, directly affecting your electricity bill and savings.

Understanding Load vs Power Consumption

Let’s break it down simply:

Load means the total wattage of all your electrical appliances combined.
Power consumption means how much energy (in units or kWh) you actually use over a billing cycle.

For example:
If your home’s load is 10 kW, it doesn’t mean you consume 10 units per hour. You may only use 3–4 kW per hour depending on your usage pattern.

That’s why calculating your solar system size based on consumption, not load, gives a more accurate result.

Common Mistakes When Sizing Solar Systems

Oversized Solar System

Many customers add up all appliance wattages and install a higher-capacity solar system.
Problem:

Higher investment cost
Unused generation if your usage is low
Longer ROI period

Undersized Solar System

Others assume they use only 50% of the total load and choose a smaller system.
Problem:

Partial offset of EB bill
Dependence on grid power continues
Low long-term savings

The Best Practice – Calculate Solar Based on Units Consumed

The ideal way to choose your home solar system in Erode is to look at your EB bill.

Check your average monthly units consumed (say 450–600 units).

A 1 kW solar system generates around 4 units/day (or 120 units/month).

So, if you use 600 units/month → 600 ÷ 120 = 5 kW solar system fits perfectly.

This simple approach helps you save money while ensuring your solar system matches your real power needs.

Advantages of Right-Sized Solar System

Reduces electricity bills effectively
Shorter payback period (usually 3–4 years)
Long-term performance stability
Maximizes government subsidy benefits
Ensures efficient use of solar energy
