Kakuma 2 — 1.3 MWp solar mini-grid design

Decentralised solar mini-grid design powering boreholes around Kakuma refugee camp, Kenya.

Problem: Boreholes serving the camp depended on unreliable, expensive power, limiting access to clean water.
Solution: Designed a 1.3 MWp mini-grid integrating generation, distribution and storage — load analysis, system sizing, equipment selection and optimisation with industry-standard tools.
Results: 1.3 MWp decentralised generation designed
Reliable borehole pumping for the community
Optimised sizing for generation, distribution and storage

Energy Audit

ASHRAE Level II energy audit — Mövenpick Hotels

Comprehensive building-systems audit with costed energy conservation measures and ROI analysis.

Problem: Rising utility consumption with no clear benchmark of where energy was being lost across the property.
Solution: Assessed HVAC, lighting, domestic hot water, plug loads and control strategies, benchmarked utility data and identified Energy Conservation Measures.
Results: No-cost/low-cost and capital ECMs identified
Payback, ROI and annual savings quantified
Foundation set for future retrofit projects

Automation

Industrial automation commissioning & field service

Installation, commissioning and maintenance of automation systems for manufacturing, utilities, FMCG and processing clients.

Problem: Clients faced automation faults and electrical downtime with limited on-site diagnostic capability.
Solution: Installed, configured and commissioned PLCs, HMIs, VFDs, servo drives, control panels and sensors; ran diagnostics and preventive maintenance with full service reports and wiring diagrams.
Results: Improved system uptime across client sites
Faster fault diagnosis and resolution
Documented wiring diagrams and service reports

Training

Industrial automation training programme

Hands-on PLC, HMI, SCADA and industrial wiring training for technicians and engineers in Nairobi.

Problem: Technicians had theoretical knowledge but limited practical confidence with modern automation hardware.
Solution: Built comprehensive training manuals and assessments, and delivered practical lab exercises across PLC programming, HMI design, SCADA basics and industrial wiring.
Results: 50+ technicians and engineers trained
40% measured competency improvement
Reusable manuals and assessment framework

Thika Technical Training Institute — 339.76 kWp solar + 430 kWh BESS

Full AutoCAD as-built design for a 339.76 kWp DC / 300 kWac rooftop PV plant with battery storage at TTTI, Thika (Gizaa Power Solutions Ltd, DWG-TTTI-PV-03).

Problem: The institute needed a resilient, low-cost campus supply that could ride through grid instability while serving heavy workshop loads.
Solution: Designed and drafted the complete electrical package: SLD/MLD AC-DC topology with string-to-inverter assignments, busbar arrangements and SmartLogger monitoring; dimensioned AC Combiner and ESS Control board enclosures; mini-rail and full-rail roof mounting with clamp and structural details; and a TS10 ESE lightning arrestor pole with earthing and foundation specs.
Results: 339.76 kWp DC / 300 kWac with a 430 kWh (600 kW) battery bank
548 × Jinko 620 W modules and 6 × Huawei SUN2000-50KTL-M3 inverters
504.4 MWh/year expected yield — 1,484.6 kWh/kWp at 75.0% PR
Complete as-built drawing set: SLD/MLD, panel details, mounting, lightning & earthing

KINAP Workshops — 253 kWp rooftop PV system

253 kWp DC / 200 kWac grid-tied PV system for The Kiambu National Polytechnic workshops, modelled in PVsyst V8.1.3 for Gizaa Power Solutions.

Problem: Workshop machinery drove high daytime demand charges, with no on-site generation to offset peak consumption.
Solution: Sized a 1.26 DC:AC array of 408 × 620 Wp monocrystalline modules across four Huawei 50 kWac inverters, then ran full PVsyst yield, shading and loss modelling to validate production and carbon savings.
Results: 253 kWp DC / 200 kWac, DC:AC ratio 1.26
363,090 kWh/year P50 — 1,435 kWh/kWp/year specific production
76.38% performance ratio
≈443.13 tCO₂ lifetime net balance (≈3,605.5 tCO₂ replaced over 30 years)

KIST Tuition Block — 126 kWp rooftop PV system

126 kWp DC / 100 kWac rooftop PV system for the KIST tuition block at The Kiambu National Polytechnic, modelled in PVsyst V8.1.3.

Problem: The tuition block ran entirely on grid supply, with lighting, IT and HVAC loads coinciding with peak solar hours.
Solution: Configured 204 × 620 Wp monocrystalline modules on two Huawei 50 kWac inverters at a 1.26 DC:AC ratio, with PVsyst simulation of irradiance, losses and lifetime emissions balance.
Results: 126 kWp DC / 100 kWac, DC:AC ratio 1.26
185,717 kWh/year P50 — 1,468 kWh/kWp/year specific production
77.08% performance ratio — highest of the three sites
≈1,378.6 tCO₂ lifetime net balance (≈1,844.2 tCO₂ replaced over 30 years)
