Projects

These references show what was deployed, why the customer needed it, and what changed after commissioning. For your project, we size against your own load and tariff data rather than copy a case headline.

We publish headline metrics only where the customer or installer agreed to the wording. Detailed timelines, single-line excerpts, and test reports stay under NDA and ship with serious inquiries. See Trust & Quality for what buyers typically verify before wiring funds.

Nigeria projectNigeria project. Installed residential system with visible inverter, battery, and cable routing.

Nigeria

Residential hybrid backup

Scope: 10 kW PV + 10 kWh storage

Our role: Equipment supply plus remote commissioning support (local installer executed civil and AC wiring).

Challenge: Frequent outages and high diesel dependency for evening loads.

Outcome: Grid/diesel reliance reduced and backup availability improved for critical circuits.

Final savings vary by tariff and actual load profile; figures are validated at quotation stage.

United States projectUnited States project. Suburban rooftop array with clean module layout and code-compliant mounting.

United States

On-grid residential

Scope: 15 kW PV system

Our role: Module and inverter package to licensed EPC; customer-side utility paperwork handled by the installer.

Challenge: Homeowner required predictable annual bill reduction with utility-compliant design.

Outcome: Estimated yearly savings in the USD 3,000-4,500 range under local tariff assumptions.

Payback depends on utility rate changes, shading, and installer commissioning quality.

Mauritius projectMauritius project. Agricultural site with greenhouse and PV generation assets in one frame.

Mauritius

Agricultural hybrid supply

Scope: 150 kW PV + 60 kWh storage

Our role: Battery, inverter, and integration documentation; on-site FAT witnessed before container dispatch.

Challenge: Site required stable 24-hour energy for controlled-environment farming.

Outcome: Continuous operation supported with improved predictability for irrigation and climate equipment.

Runtime and autonomy are modeled against seasonal irradiance and maintenance discipline.
