Before you write

What helps us respond well.

The more precisely you describe the project, the faster a useful response comes back. These are the six things an EPC or component desk needs to price anything.

What information should I include with an EPC enquiry?+
At minimum: site location (GPS or city), target capacity, off-taker type (utility / industrial / C&I), target COD, and a rough land area or roof area. If you have a grid point of connection, utility voltage class, and a preferred PPA tenor — even better.
How do you handle confidentiality on project enquiries?+
We treat every project enquiry as confidential. Technical and commercial information is shared only with the engineering and commercial team assigned to your enquiry, and formal confidentiality terms can be put in place on request (typically within 48 hours).
Do you quote containers or only full EPC?+
Both. Our Components desk quotes module container orders (CIF, FOB, DDP incoterms). Our Brand Portfolio desk quotes inverter, BESS and grid equipment packages. Our EPC desk quotes turnkey projects. Three distinct workflows, three distinct response SLAs.
Can you respond in Arabic / Chinese / French?+
Yes. Our regional desks operate in Arabic, English, Chinese, French and Kiswahili. Written proposals can be delivered in the client's preferred language; our primary contract language is English.
I'm a lender / IE — can I request a data-room access for diligence?+
Yes. Access is provided to lenders, independent engineers, insurance underwriters and qualified institutional investors on request. The room holds engineering packages, FAT records, warranty agreements, insurance certificates, financial summaries, and delivered-project case studies.
Are TPC modules available for in-country stocking distributors?+
Yes, for qualified distributors. Distributor applications go through a commercial and technical review — track record, annual volume, service capability — and successful applicants are assigned a regional account manager and brand portfolio access.

"We don't sell faster than we can engineer. If your project fits our capability envelope, you will hear a clear yes within a week. If it doesn't, you will hear a clear no — and a useful recommendation."
