Calculating your home's energy requirements for solar panels requires a few steps. Here's a simplified process: Gather your electricity bills: Collect your electricity bills for the last 12 months. These bills should show your monthly energy usage in kilowatt-hours (kWh). Calculate your average monthly usage: Add up the total kWh from each month's bill and then divide by 12 to get your average monthly usage. Determine daily energy usage: Divide your average monthly kWh by the approximate number of days in a month (30) to get your daily energy usage. Factor in Sunlight Hours: Michigan averages about 4.2 hours of peak sunlight per day annually. Divide your daily energy usage by these peak sunlight hours. The result is an estimate of the kW capacity your solar system would need to fully cover your energy usage. Remember, this is a rough estimate. The actual solar panel capacity might vary based on various factors such as the efficiency of the solar panels, the angle of installation, shading on the panels, etc. It's also worth noting that this calculation assumes you want to cover 100% of your energy usage with solar power. If you're aiming for less, adjust the calculation accordingly. To get a more accurate estimate, it's always a good idea to consult with a professional solar installer. They can assess your specific situation and give you a detailed analysis.
