Net Metering

Net Metering

 
Energy consumed through solar panels is billed under the concept of ‘net metering’.
Net Metering is an electricity policy designed for users of roof-top based panels to “self–generate” power for their own consumption primarily and thereafter allow their electric meters to run backwards and send the extra power generated back to the main grid.  However, net metering takes into account the difference of excess energy fed back to the grid and total energy consumed from the grid by the system owner.
Net metering allows the solar PV system owner to sell excess solar power generated to the utility company or buy deficit power from the utility company using a bi-directional meter to track this energy exchange. A bi-directional meter is installed in the supply line to register import and export of power. Typically, a solar system produces more units of power when there is more sunlight and vice versa. With net metering in place, the user of the solar system does not have to bother about the wastage of extra units generated, as the units are being fed to the grid and can be used during days with lesser sunlight. Hence, it balances out the extra generation and deficit; for example, if in summer, solar power generates 150 units and load requirement is 100 units, then 50 units can be fed back to the grid. In winter, solar power generates only 120 units and load requirement is 150 units, then 30 units can be consumed from the grid. Thus, this brings about a balance in their electricity bills.
 
Net-Metering in Lebanon
 Net metering is a financial agreement in which utility customers generate some of their own electricity and use a single meter to measure the net electricity bought from the utility. At various times, the customer will not use all the electricity generated. The excess is fed back into the grid and makes the meter run backwards. When the meter is read, it will usually show a net purchase from the utility. If the customer generated more electricity than was consumed that month and the meter shows a negative value, it will be credited to the next month’s bill. Knowing that this cycle resets in the beginning of each year.
