Agar aap solar lagwana chahte ho par ye decide nahi kar pa rahe ki ghar ke liye kitne watt ka solar chahiye, to yeh guide aapke liye perfect hai.

Har ghar ki power consumption alag hoti hai.
✔ Kuch ghar sirf lights + fan chalaate hain
✔ Kuch ghar me fridge, TV
✔ Kuch me AC + washing machine + geyser

To solar ki requirement load ke hisaab se decide hoti hai.

Is blog me hum step-by-step samjhenge:

• Ghar ke load kaise calculate hota hai
• 1kW–10kW solar system me kya chalta hai
• Old bill se kaise calculate kare
• Grid vs off-grid options
• Price, generation, space requirement

Chaliye start karte hain ⚡☀️

📌 Step 1: Ghar Ka Total Load Calculate Karein

Sabse pehle list banaiye ki ghar me kaun kaun se appliances chalte hain.

Household Load Chart (Watt Approx)

Example Load Calculation

• 4 bulbs (10W × 4) = 40W
• 3 fans (70W × 3) = 210W
• 1 TV = 120W
• 1 fridge = 250W
• 1 laptop = 50W

Total Load = 670W

Rule:
Solar system always total load se 20–30% zyada choose karna chahiye.

📌 Step 2: Electricity Bill Se Solar Size Kaise Decide Karein

Apna monthly electricity bill dekhiye.

Formula:

Monthly units / 30 = Daily units
Daily units / 4 = Required kW solar

(4 units per kW per day – Indian weather average)

Example:

Bill = 300 units/month
300 / 30 = 10 units/day
10 / 4 = 2.5 kW solar system required.
