Estimator pricing basis

The online estimator prices a system in two parts:

  • MARSTEK equipment at the Philippine SRP from the price list, unchanged.
  • Solar installation (panels, mounting, inverter, wiring, labour, design) from the defaults below. They were set on 9 October 2026 from published Philippine installer packages and shop listings.

Admins can change every value on the estimator's admin page. These are market-based estimates, not supplier quotes. Replace them with Silvera's own supplier and installer quotes as they come in.

Defaults and their basis​

All values are VAT-inclusive retail prices.

The quote shows the VAT inside the total. MARSTEK SRPs are consumer prices that already include VAT, so VAT is not added on top. The design share is not applied to MARSTEK equipment.

Check against published packages​

The solar part of an estimator quote (the total without the MARSTEK battery) lines up with VAT-inclusive installed grid-tie packages:

What still needs a real quote​

  • Panel model and price. Get dated quotes for the same model at 1, 5 and 10 pieces and a full pallet, delivered to Batangas, ex-VAT and VAT-inclusive.
    • The MARSTEK Infinity (695–720 W) launch is public (BusinessMirror, 18 Aug 2026), but no price or model code is. marstek.ph is still a "launching soon" page.
    • Its specs match DMEGC's earlier Infinity G12T-B66HSW 695–720 W panel. No public source names DMEGC as the maker.
  • Installer labour and scope for Batangas roofs.
  • BATELEC fees and rates. No published net-metering fees or current rates were found for BATELEC I or II. Ask customers which utility serves them.
  • MARS I PLUS expansion box/kit for more than 3 battery modules. The estimator flags it but does not price it.
  • VENUS E Mini price. It is not on the SRP flyer, so its price stays marked indicative.
