Secure your investment

Existing & Potential Solar PV System Owners

PV investments are heavily front-loaded, with the benefits spread over twenty years or more. The way to maximise them is to get it right the first time — and to know, independently, that it was done right.

What we do for you

9 services

01

System design, component and installation reviews

Independent review of designs, components and installation works — before you pay the final invoice, and while the contractor is still on site.

02

Performance tests and system optimisation

Performance assessment against what the system was designed to produce, with specific recommendations for optimisation.

03

Fault diagnosis and repair

Inspections, fault diagnosis and repairs. Whatever the problem with your solar PV plant, we have almost certainly seen it before.

04

Real-time monitoring and reporting

Effective monitoring with analytics that tells you when output has drifted, rather than leaving you to notice it on a bill three months later.

05

Scheduled maintenance

Panel cleaning and routine maintenance on a schedule, with a record of what was done. Soiling in Ghana takes real output away quietly.

06

General advisory services

Advice on PV system types, technology and component selection, product warranties, developer recommendations and financial models.

07

Transactional advisory (Owner's Engineer)

Project conceptualisation, feasibility study, supervision and reviews, procurement document preparation, evaluation and developer selection, design review, funding and contractual advice, construction monitoring and supervision.

08

Testing and commissioning

Independent testing and commissioning — the person signing off the system is not the person who sold it to you.

09

Prefeasibility studies

Supply-and-demand analysis to inform system design and procurement, including site assessment, load measurement and yield studies.
