Onyxx designs and manages rooftop and ground-mounted solar PV systems that reduce electricity costs, stabilize supply, and cut emissions for institutions and communities. Our focus is on projects where power unreliability and high tariffs are real operational risks.
– Rooftop PV systems for schools, hospitals, housing developments, and commercial buildings
– Ground-mounted solar plants for institutional and municipal customers
– Hybrid systems integrating existing diesel generators or grid supply
– Solar-powered water pumping systems for boreholes and distribution networks
– Performance monitoring and reporting for systems above 30 kW, including monthly performance-versus-forecast reports for clients.
– High and volatile grid power bills
– Frequent power cuts that disrupt learning, healthcare, or essential services
– Heavy reliance on diesel generators and rising fuel and maintenance costs
– Pressure to reduce carbon footprint and meet ESG targets
– Client: 1,450-student boarding school in Siaya County, Kenya
– Challenge: High and erratic electricity bills, frequent grid interruptions, and generator dependence
– Solution: 100 kWp rooftop PV system under a BOT structure, based on feasibility and site analysis
– Outcome (target): Energy independence for core school operations and significant reduction in monthly electricity costs over the PPA term.
– Contract models: EPC, Power Purchase Agreements (PPA), or Build–Operate–Transfer (BOT) depending on client preference and financing
– Funding: Integration with grants, concessional loans, and private capital; Onyxx-EW can support project owners in building bankable proposals.
