  2. Invite us over for a technical evaluation

    Meralco will evaluate your application and requirements through a field study called the Distribution Impact Study (DIS). The DIS is a study we conduct to find out the potential effect of your solar installation on our distribution system. If DIS results show an upgrade of the distribution facilities is needed, a Customer Renewable Energy Asset Study (CREAS**) will be conducted. CREAS fees will be determined depending on the asset study conducted to determine the engineering solution that would be needed to accommodate the RE installation.

    After this, we’ll coordinate to your solar installer the proper interconnection of your solar PV installation to your load and to the Meralco system. Your solar installer shall then finalize the details of your solar PV interconnection.

    As part of the technical evaluation, Meralco makes use of a hosting capacity table to determine the maximum allowable capacity for RE systems to be integrated without causing adverse effects on the normal system operation of the distribution network. To learn more about Meralco’s hosting capacity see the table below:

    Transformer kVA Hosting Capacity (kWac)
    10 2 kW
    15 4 kW
    25 10 kW
    37.5 14 kW
    50 19 kW
    75 29 kW
    100 38 kW
    1. This table only represents the aggregate maximum allowable capacity for solar PV systems per transformer level. Meralco conducts its final assessment depending on actual system conditions.
    2. This is only applicable for single-phase distribution transformers. For other transformer types, it will require transformer loading and/or actual field measurements to assess the hosting capacity.
    3. This hosting capacity is only applicable within the Meralco franchise area.
    4. Hosting Capacity (HC) is defined as the maximum solar PV systems that can be integrated without causing any adverse effect on the normal system operation of the distribution network. The existing MERALCO HC quantification is based on worldwide models and methodologies. The MERALCO HC method properly modeled the low voltage network, secondary line, and service drop, load, and solar PV generation system. An appropriate power flow method was used and was based on the backward/forward sweep radial power flow algorithm coded in MATLAB platform.
    5. Consult your Meralco representative for further details.
  3. Schedule an inspection to get final approval

    We will also inspect your facility and service entrance to ensure compliance to standards. Once approved, we’ll install your bi-directional and REC* meter and conduct the testing of the interconnection of your solar PV in our system.

  4. Power up your installation

    Once we have replaced your existing meter with a bi-directional meter, installed a REC* meter and have successfully tested and commissioned your solar PV, you can now safely use and enjoy the benefits of your solar Net Metering installation in powering your home.
