High effort to bid.

Written from the published notice — the full tender document was not available to us. Download it from the source before bidding: eligibility rules, fees and specifications may only appear there.

• The panel line gives a wattage but not how many panels each 3kVA system needs, so the array size per unit is unpublished.
• The delivery period is recorded as 4 years against a 30-day bid validity, which is a very long horizon for a fixed price on imported equipment — confirm what it actually refers to.
• The solar cable line gives no length or size.
• The notice does not say whether existing wiring, roof condition or certification is the bidder's responsibility across 15 occupied housing units.
• Run under the Competitive Bidding Method, so expect a full technical and financial submission.
