Engineering Advisory

Solar + BESS Engineering Advisory

Your independent technical partner — from project concept to operations.

Mission

Address the world's energy crisis by making clean and affordable energy available for everyone — transforming industries with clean, innovative technology for a sustainable future.

Vision

An equal world where everyone has access to affordable, reliable and sustainable energy.

The industry challenge

Solar + BESS projects carry technical risk that grows with complexity

01

Grid integration

Interconnection and compliance requirements are becoming project-critical.

02

Technology selection

Choosing the right BESS configuration and OEM affects performance for decades.

03

EPC/OEM coordination

Multiple contractors and suppliers must be aligned to a single technical outcome.

04

Performance guarantees

Yield, availability and degradation assumptions need independent verification.

05

Construction quality

Design intent has to survive contact with the construction site.

06

Commissioning

Systems must prove they perform to specification before handover.

07

Warranty & degradation

Long-term asset value depends on evidence gathered from day one.

08

Bankability

Lenders and investors need independent technical evidence, not vendor assurance.

Where we fit

The technical bridge

YESEN Technologies acts as the independent technical bridge between investors, developers, EPCs, lenders and equipment suppliers. We sell engineering judgment, not just drafting hours.

  • • Repeatable delivery playbook: concept to operations
  • • Regional execution with international standards
  • • Independent decisions on design, risk and bankability

What this means for you: we sit on your side of the table — one independent engineering voice from first feasibility sketch to final handover, accountable only to your project's outcome.

Owner's engineering

Your technical representative, concept through handover

  1. 01Your technical representative
  2. 02Site & resource review
  3. 03Detailed design review (PV/BESS, SLDs, SCADA/EMS)
  4. 04Supply chain & OEM due diligence
  5. 05Construction site supervision
  6. 06Commissioning & performance testing

What this means for you: confidence that CAPEX, schedule and technical quality are actively protected — not just documented after the fact.

Independent engineering / TDD

One independent opinion, for every stakeholder

An independent technical opinion for investors, lenders and asset owners.

  1. 01Technical Due Diligence (TDD)
  2. 02Energy & Performance Yield Review

BESS technical advisory

Dedicated depth where hybrid projects carry the most risk

01

Augmentation & degradation

Independent review of long-term capacity planning and degradation risk.

02

Fire & safety review

Independent assessment of BESS safety design and risk.

03

Integrated PV/BESS design review

BESS reviewed as part of the wider electrical and controls design.

04

BESS supply chain review

OEM due diligence extended to battery technology suppliers.

05

System architecture & sizing

Dedicated standalone sizing studies.

06

PCS / EMS review

Standalone controls-level technical review.

07

Thermal management

Dedicated thermal-risk assessment.

08

Integration studies

Formal Solar + BESS integration deliverable.

What this means for you: the safety, degradation and integration risks unique to hybrid systems get specialist attention a standalone solar review would miss.
