To get a more granular understanding of your electricity needs, convert your monthly usage into daily usage. Divide your average monthly usage by 30, which is the approximate number of days in a month.

Example: With an average monthly usage of 83 kWh, your daily usage would be:

83𝑘𝑊ℎ 30 =2.7 𝑘𝑊ℎ/𝑑𝑎𝑦

Step 3: Estimate Solar Panel

Output Solar panels are rated by their power output in watts, but their actual energy production varies based on factors such as location, angle, and shading. On average, a solar panel produces between 250 and 400 watts per hour. To estimate the daily energy output, you need to consider the average peak sunlight hours in your location. This information is often available from local solar energy resources or online databases. For

instance, if your location receives 5 peak sunlight hours per day, a 300-watt solar panel would generate:

300 𝑤𝑎𝑡𝑡𝑠∗5 ℎ𝑜𝑢𝑟𝑠=1500 𝑊/ℎ =1.5𝑘𝑊ℎ/𝑑𝑎𝑦

Step 4: Calculate the Number of Panels Needed

Now, divide your average daily electricity usage by the daily output of a single solar panel to find out how many panels you need.

Example: With a daily usage of 1.5 kWh and a panel output of 1.5 kWh/day, the number of panels required would be:

2.7𝑘𝑊ℎ/𝑑𝑎𝑦 / 1.5 𝑘𝑊ℎ/𝑑𝑎𝑦 𝑝𝑒𝑟 𝑝𝑎𝑛𝑒𝑙 =2 panels

Step 5: Adjust for System Efficiency and Losses

It's important to account for system inefficiencies and potential losses, such as shading, dust on panels, and inverter inefficiencies. A typical practice is to add a 25% buffer to your initial calculation.

2∗1.25 = 3 𝑝𝑎𝑛𝑒𝑙𝑠

Step 6: Consider Future Needs Account for Growth

If you anticipate an increase in energy usage (new appliances, electric vehicles, etc.), you might want to size up your system.

Example: If you plan for a 10% increase in usage

2.7 kW × 1.1 = 2.6 kW

Final Considerations

• Panel Wattage: The calculations assume a 300-watt panel, but panels come in various wattages. Adjust the calculations based on the specific panels you plan to use.

• Sunlight Hours: Peak sunlight hours can vary significantly based on your geographic location. Ensure you use accurate data for your area.

• System Losses: Consider factors such as shading, panel orientation, and efficiency of inverters and other system components.
