Seamless and cost-effective delivery

Solar Businesses & Project Developers

Cost-effective and timely delivery at the highest international standards makes a happy client. We work alongside developers and EPCs across Ghana and West Africa — on the whole project or on the parts you would rather hand to a specialist.

What we do for you

12 services

01

Market research, analysis and recommendations

Our knowledge of markets across West Africa and our technical grounding make us well placed to advise on PV development in Ghana and the sub-region. We conduct industry-wide studies using data-driven and evidence-based methods to identify PV adoption characteristics and motivations, market segments, trends and barriers to entry.

02

Licensing and permit acquisition

We assist developers and clients to meet regulatory requirements and obtain the appropriate permits and licences for their PV projects, including Energy Commission licensing and utility interconnection approvals.

03

Project management and construction

Our team can manage every phase of your PV construction project, or just the parts you need covered: comprehensive supervision, inspections, mechanical and electrical installation, testing and commissioning.

04

Engineering design and component selection

Sizing of all components, mechanical drawings (PV layout plans, mounting structure drawings), electrical drawings (single-line diagrams for power and communications), transformer selection and feeding-point diagrams, bill of materials, technical requirements for components, and selection of main component suppliers.

05

Advanced shading analysis and yield studies

Our team works with the most accurate shading-analysis tooling available, combined with our own 3D modelling, to produce shading and yield analysis you can put in front of a lender.

06

Site and PV plant 3D modelling

We build 3D models of existing sites and plants, and render structures, arrays and power rooms that have not been built yet, to support your analysis and design decisions.

07

Load profile and demand analysis

A well-designed PV plant is one backed by real load measurement, not an assumption. We use Class A certified power analysers to deliver accurate load measurement and demand profiling for business.

08

Test equipment sale and hire

Load measurement, PV design and test equipment available for sale and for hire — including instruments most contractors cannot justify buying outright.

09

Inspections, testing and commissioning

Advanced PV inspection and testing equipment, including drones with thermal sensors, for accurate inspection, testing and commissioning results.

10

Fault diagnosis, maintenance and repairs

Our electrical engineers and PV practitioners diagnose and repair faults within your plant, or recommend the solution if the fix belongs with somebody else.

11

Real-time monitoring and reporting

Affordable monitoring for individual systems and for fleets, on a single platform that does not depend on the inverter brand or manufacturer.

12

Project lead generation

Through our engagement with consumers we continuously generate project leads for solar PV developers.
