How much Solar Panels needed for Fridge, Water Pump and AC?

The number of solar panels needed to power a fridge, a 1 HP water pump, and an air conditioner (AC) depends on several factors, including the energy consumption of each appliance, the location and climate conditions, and the efficiency of the solar panels and the entire solar system. Here’s a general guideline to help you estimate the number of solar panels required:

Determine the Energy Consumption of each Appliance

• Fridge: Look for the wattage rating on the fridge’s label or user manual. Fridges typically consume around 200-800 watts, depending on size and efficiency.
• Water Pump: A 1 HP (horsepower) pump typically consumes around 750-1000 watts.
• Air Conditioner (AC): AC units vary widely in energy consumption. You’ll need to find the wattage rating on the AC unit itself or in its documentation. AC units can range from 2,500 watts for smaller units to 5,000 watts or more for larger ones.
• Fans: Wattage of the ceiling fan can be found in the user manual or in the device itself. On average ceiling fan uses 75 watts
• Light Bulbs: Incandescent light bulbs on average runs on 60 watts of electricity. While LED lightbulbs uses about 10 watts.

Calculate the daily energy consumption:

Multiply the wattage of each appliance by the number of hours it runs daily. For example, if your fridge uses 200 watts and runs for 24 hours a day, it consumes 200 x 24 = 4,800 watt-hours (4.8 kWh) per day.

Add up the daily energy consumption of all appliances to get the total daily energy consumption in watt-hours.

Consider location and climate:

The amount of sunlight your location receives affects solar panel efficiency. You’ll need to know the average daily sunlight hours in your area to estimate the energy production of your solar panels.

Calculate the required solar panel capacity:

Divide your total daily energy consumption by the average daily sunlight hours to get the solar panel capacity in watts. For example, if your total daily energy consumption is 10,000 watt-hours (10 kWh), and your location receives an average of 5 hours of sunlight per day, you’d need a solar panel system with a capacity of 10,000 watts / 5 hours = 2,000 watts (or 2 kW).

Calculate the number of solar panels:

The number of solar panels needed depends on the wattage of individual panels. Typical residential solar panels have a capacity of 250-400 watts each. Divide the solar panel capacity (in watts) by the wattage of individual panels to determine the number of panels required. For a 2 kW system, using 300-watt panels, you’d need approximately 6-7 panels (2,000 watts / 300 watts per panel = 6.67 panels).
