Determining how many solar panels you’ll need for your home means first knowing what your
goals are. There is a lot more than just the size of your house or building that needs to be
considered when determining the number of panels you will need.
To calculate how many solar panels you need, follow these easy steps:
1.Determine your average monthly electricity usage
We like to look at your most recent 6 to 12 months of energy usage. Thanks to Net Metering, we can use this history to properly size your system to cover 100% of your yearly usage in most cases.
2.Calculate your daily kWh usage
You can find this information on your latest power bill.
3. Estimate the amount of sunlight your solar panels will receive
The amount of direct sunlight your roof receives will vary based on where you live and the time of year (another reason why Net Metering is a great benefit).
4. Factor in your potential solar power usage
A larger home typically needs more panels to cover its consumption. However, usage habits and the efficiency of home appliances are also important. Two homes of the same size can have very different energy needs.
