Match energy output with expected numbers
To check if your system works well, compare its energy output to expected numbers. Look at your system’s specs to know how much energy it should make. For example, a 5-kilowatt system makes more power during sunny hours.
Write down your inverter’s energy data over time. Use this record to spot any unusual changes. If the numbers don’t match, there could be a problem with the inverter or panels. Fixing these issues early avoids bigger problems later.
Tip: If you think there’s a problem but aren’t sure, try resetting the system. This can fix small errors and get things back to normal.
Check the utility meter for energy sent to the grid
Your utility meter can show if your solar system sends energy to the grid. This step is important to confirm your system works well and makes extra energy.
First, find your utility meter. Most modern meters are digital with different readings. Look for one labeled “export” or “sent to grid.” This shows how much energy your system sends back to the utility company. If the number goes up during sunny hours, your system is sending power.
Some meters have arrows or symbols to show energy flow. An arrow pointing away from your home means energy is going to the grid. If the arrow points toward your home, it means energy is coming from the grid. Knowing these symbols helps you check your system’s performance.
Tip: Check the meter at different times, like during sunny hours and at night. Comparing these readings helps you see how much energy your system makes.
If the meter doesn’t show energy being sent during the day, there might be a problem with your inverter or panels. Call a professional to check your system. Checking your utility meter often ensures your solar system works well and saves energy.
Watching your utility meter helps confirm your solar system meets your energy needs. It can also help you earn credits through net metering programs. This simple habit keeps you informed about your solar system’s performance.
