To determine the number of solar panels needed for a 200 amp service, we need to consider the average energy consumption and the solar panel's power output.
- Calculate Average Energy Consumption: First, determine your average daily energy consumption in kilowatt-hours (kWh). A 200 amp service does not directly indicate energy consumption, as it only refers to the capacity of the electrical service. The actual energy usage depends on your household's electrical devices and habits. To find your average daily energy consumption, check your electricity bills, which usually provide this information.
For example, let's assume your average daily energy consumption is 30 kWh.
Determine Solar Panel Output: Next, find the power output of the solar panels you plan to install. Solar panels are rated in watts (W) or kilowatts (kW). Let's assume you have 300W solar panels.
Calculate the Number of Solar Panels: Now, divide your average daily energy consumption by the solar panel output to determine the number of solar panels needed.
Number of solar panels = Average daily energy consumption (kWh) / Solar panel output (kW)
Number of solar panels = 30 kWh / 0.3 kW = 100 solar panels
Keep in mind that this is a simplified calculation, and actual requirements may vary depending on factors such as location, climate, shading, panel efficiency, and battery storage (if applicable). Additionally, it's essential to consult with a professional solar installer or engineer to get an accurate assessment and design for your specific situation.
