What Size Solar System Do I Need for My House?

Determining the right system size requires analyzing your electricity consumption patterns.

We recommend reviewing your past six months’ electricity bills to understand your average monthly usage. Look at the total units (kW) consumed each month.

As a general guideline, a 1 kW system generates approximately 120-150 units per month in Bangalore’s climate. This helps calculate the capacity needed to meet your requirements.

Consider your household characteristics. Larger families with multiple air conditioners, water heaters, and appliances naturally need bigger systems. A typical 2-3 bedroom apartment usually requires 2-3 kW, while independent houses may need 3-5 kW.

Think about future needs, too. Are you planning to purchase an electric vehicle? Will you add more appliances? Factor in 20-30% extra capacity for growth.

Roof space availability also matters. Ensure you have sufficient shadow-free area to accommodate the required number of solar panels.
