You may have noticed that you’re still receiving a utility bill even after installing your solar system. This is a common occurrence and we’d like to explain why that happens, especially focusing on the relationship between your system’s size, electricity production, and your overall consumption.
Your solar system was designed based on your energy needs at the time of installation. The amount of electricity it generates depends on factors like the number of panels, available roof space, and weather conditions. However, the system’s size limits how much energy it can produce.
Even if your system was designed to cover 100% of your energy needs at the time of installation, if your consumption increases or seasonal changes reduce production, your solar system may no longer meet all your electricity needs, and you will still rely on the grid, resulting in a utility bill.
Another important factor is your electricity consumption. If your usage increases after installing solar—due to new appliances, electric vehicle charging, or lifestyle changes—your system may no longer cover all your needs. In this case, the utility will supply the extra power, and you’ll see that reflected on your bill.
Even with solar, you stay connected to the grid for times when your system isn’t producing enough power, like at night or during cloudy days. Net metering can help by crediting you for excess energy, but during periods of lower production, you’ll still rely on the grid. Additionally, nonbypassable charges (NBCs), which are small fees for grid maintenance and public programs, will always appear on your utility bill, even if your solar system generates enough energy to cover your usage.
To minimize your utility bill, consider:
Receiving a utility bill after going solar is normal. It reflects the balance between what your system produces and how much energy you use. If you have any questions or want to explore options to reduce your bill further, we’re here to help!
