C&I solar

Commercial solar designed around self-consumption and constraints

Compare realistic array sizes against daytime demand, roof and site constraints, grid conditions and future operating changes.

DECISION FILESERVICEReviewed 2 September 2026
SOLAR + BESSC&I solarPhilippinesFree initial review
01

When this matters

  • The business wants lower bills without overbuilding export capacity.
  • Roof, transformer or connection constraints may govern the design.
  • The solar project must remain compatible with later BESS.
02

What we evaluate

  • Daytime load match and curtailment risk.
  • Roof, structural, electrical and protection constraints.
  • Zero-export, net-metering or other project route.
03

What you receive

  • Variant sizing and annual energy model.
  • Constraint and permitting map.
  • Procurement-ready technical brief.

A controlled path from question to evidence

Question → evidence → decision → acceptance

Every scope states what is known, what remains open, who owns the dependency and how the result will be verified.

Zero-export does not mean “no obligations”

DOE DC2026-08-0017 distinguishes own-use zero-export solar from micro-solar. Connected zero-export installations require DU notification and effective export prevention; building-permit and ERC COC requirements depend on the category and stated exceptions. Do not apply household or micro-solar exemptions to an ordinary commercial project. We help map the actual site, owner and operating mode before a proposal becomes a commitment.

Start with clarity, not a purchase

Free initial solar + BESS assessment

Tell us what you need to improve: electricity cost, reliable power, an existing system or a public procurement. We start with a no-obligation desktop review of the information you provide.

Start with clarity, not a purchase

Free initial solar + BESS assessment

Tell us what you need to improve: electricity cost, reliable power, an existing system or a public procurement. We start with a no-obligation desktop review of the information you provide.

First: free initial assessment

You receive a short response identifying the apparent priority, missing information and a recommended next step. No site visit, measurements, engineering design, legal opinion or certification is included.

If useful: an agreed engineering scope

Only after the free assessment, we can send a separate proposal with scope, deliverables, fee and timing. It can cover measured loads, solar yield, BESS sizing, tender risks, cybersecurity or lifecycle cost. Nothing starts until you approve it.

Do not attach bills, diagrams, credentials or other sensitive files here. We will agree a secure transfer route after initial contact.

The initial desktop assessment is free. Any detailed work begins only after you approve a separate scope and proposal.

Public entities: preliminary contact does not confer preferred-bidder status or authorize an award. Any subsequent engagement must follow the applicable procurement process.
