Section 2: Sourcing Strategy & Procurement Channels

4. Who are your preferred Tier 1 / Tier 2 hardware brands?

Modules

Inverters

Batteries

5. How do you currently procure the majority of your hardware? Direct import from manufacturers in China Import via regional distribution hubs (e.g., UAE, South Africa) Purchase from local wholesalers in-country

6. What are your standard Incoterms for imported hardware? EXW (Ex-Works) FOB (Free on Board) CIF (Cost, Insurance, and Freight) DDP (Delivered Duty Paid)

Section 3: Cost Breakdown (The EXW to Landed Bridge)

To standardize data, please base your answers in this section on a standard reference unit: a 500W+ Tier-1 PV Module OR a 5kWh LFP Rack-Mount Battery.

7. Which component are you using as your baseline for the following cost breakdown? 500W+ PV Module (per unit) 5kWh LFP Battery (per unit) 5kW+ Hybrid Inverter (per unit)

8. Please provide the average estimated cost breakdown for this unit from factory to your local warehouse (in USD):

A. Ex-Works (EXW) Price

$

B. Freight (Ocean/Air) & Insurance

$

C. Official Customs Duties & VAT Paid

$

D. Port Handling, Clearing Agent & Inspections (e.g., BIVAC/SONCAP)

$

E. Average Demurrage / Storage Penalties incurred per unit

Never - Customs align perfectly with official policy Rarely - Minor administrative fee differences Frequently - Constant negotiations and unofficial levies Always - Official exemptions are rarely honored in practice

Section 5: Market Pivot & Local Assembly Appetite

13. If high-quality, Tier-1 equivalent components were assembled locally in your country, eliminating import lead times and port friction, what is the maximum price premium you would accept over the Chinese EXW price? 0% - It must match the EXW China price exactly 1% - 10% premium (Offset by savings on freight/demurrage) 11% - 20% premium (Offset by immediate availability and local warranty) >20% premium

14. Rank the following benefits of a localized supply chain from most important (1) to least important (4):

Assign a unique rank 1-4 to each benefit.

Zero import port delays / demurrage

Same-day / next-day equipment availability

Localized warranty support and immediate unit replacement

Elimination of forex currency allocation challenges for imports

15. Would you be willing to sign a conditional off-take or preferred-vendor agreement with a local assembly facility if they met your technical specifications and landed cost requirements? Yes, we are actively looking for reliable local supply Maybe, pending a pilot project and technical audit No, we are locked into existing international supplier contracts

16. (Optional) Please leave your contact information if you would be open to a 10-minute follow-up interview with Granville Energy's product team.
