Exported solar is not valued like a retail purchase

Approved net metering uses a bidirectional meter to record imports and exports. Export credit is linked to the utility's applicable generation-cost methodology, not a one-for-one refund of every retail bill charge. Ralos defaults to PHP 16/kWh import and PHP 10/kWh export as October 2026 user-supplied planning assumptions, not verified tariffs; confirm the current rate and credit treatment with your utility.

For a larger array with persistent surplus, compare the added annual export benefit against the incremental net-metering project cost. Storage offers a different service: shifting energy and, with the correct backup equipment, resilience. Neither option always gives a better financial return.

Ralos planning allowances

Ask for a breakdown of professional plans, permit processing, service-entrance work, utility-related items and installer services. Confirm inclusions, taxes and exclusions before comparing quotations. Outside Meralco's franchise, ask the serving utility for its own process.

Keep official fees separate

Meralco's current documentary checklist lists a PHP 1,500 COC application fee and a residential difference-in-meter-cost fee of up to PHP 3,000 when applicable. Those items do not explain a PHP 50,000 project allowance by themselves. Site works and professional services must be identified separately.

Your export-readiness checklist

Begin the paperwork while learning from your Starter. Plan expansion as approval approaches, subject to final design and a separate approved order.

The available capacity of your local distribution network can constrain a proposed installation. Approval is not guaranteed. Even a small non-export system needs utility coordination and export-limiting protection for its design.

  • Start with your serving distribution utility: request its current application pack and technical checklist.
  • Coordinate service-entrance protection, meter location and electrical plans with qualified professionals.
  • Arrange the LGU's Certificate of Final Electrical Inspection (CFEI). Meralco requires it after service-entrance inspection and before meter replacement, if applicable.
  • Complete the utility assessment, documents, agreement, meter work and commissioning.
  • Count export credits only after utility authorization and activation.

Learn first, expand deliberately

Keep current no-net-metering savings separate from a future export scenario. Unused production is energy, not a percentage of your bill. Future credits depend on activation, actual surplus and applicable rates.

Batteries offer backup resilience, not an automatic improvement in payback. Review actual use before adding equipment.
