On this page you can find:
Scenario 1: Your renewable energy system is online and producing enough energy to power all the loads in your home and send excess energy back through the meter onto SMPAâ€™s power lines.
Energy is flowing from your system to your home and onto SMPA's power lines.
Scenario 2: Your renewable energy system is offline. All energy being used to power the loads in your home is coming from SMPA.
Energy is flowing only from SMPA's power lines to your home.
Scenario 3: Your renewable energy system is online, but is not producing enough energy to power all the loads in your home. You are using all the energy your system is producing and some energy from SMPA.
Energy is flowing from your system to your home and from SMPA's power lines to your home.
What will my inverter measure and display?
Most, but not all, inverters will have an LCD screen or online monitoring package that shows the daily and lifetime kWh output of the renewable energy system. The readings will show AC kWh generated by your system. These kWhs will either be used up in real time by loads in the building or go through the meter onto the grid or both.
What will my SMPA meter measure and display?
Your meter will display three different registers: the reset screen, the kWhs consumed from the grid and the kWhs your system has put back onto the grid. The meter will rotate through these three items displaying each reading for approximately six seconds.
You will recognize the reset screen because the reading will appear as all 8s or 0s. You will recognize the screen that shows the kWhs consumed from the grid by the plus symbol on the display. Often times the meter will use the minus symbol to identify the screen that displays the kWhs your system has placed onto the grid.
Please check out our Reading Your Net Meter document for a visual example.
What will my SMPA bill look like?
Your bill will display the common line items that are on all SMPA bills, such as the access charge and the applicable fees and taxes from your county/city. The kWh line item will show the total amount of energy you pulled from the grid. There will also be an adjusted net metering credit line that shows the credit that was applied to your account against the kWh total.
In the message to the members sections you can find a total for the amount of energy your system put back onto the grid. The bill will not show the total amount of energy your system produced or the amount of energy from your system that was consumed in real time.
Please check out our Reading your Net Meter Bill document for a visual example.
How will I be credited for any excess energy my system produces?
Each month the kWh total that your system puts onto the grid will be credited against the kWh total that you used from the grid. If your system put more kWhs onto the grid than you used from the grid, the excess will be reserved and applied as credit in future months as needed.
Example: Last month the net metered system put 450 kWh onto the grid and you used 300 kWh from the grid. 300 of the 450 generated are used to credit against the 300 kWhs consumed. The remaining 150 kWh carry forward to future months.
This month the net metered system put 250 kWh onto the grid and you used 350 kWh from the grid. The 250 generated is credited against the 350 consumed leaving 100. You still have 150 kWh in credits, so 100 of these can be applied to the remaining 100 for this month leaving you with 50 to carry forward to future months.
