Solar PV, solar thermal and heat pump systems engineered for East African conditions — cutting energy costs and carbon while strengthening the reliability of your building's power supply.
Service Overview
What we deliver
Energy is one of the largest operating costs in any commercial or industrial building in East Africa — and one of the least predictable. Grid tariffs rise, supply can be interrupted, and diesel backup is expensive to run. The region also enjoys one of the most consistent solar resources anywhere. Properly engineered renewable energy systems turn that resource into lower bills, greater energy security and a measurable reduction in carbon emissions.
TechMEPi Engineering designs and supervises renewable energy installations as an integrated part of a building's mechanical and electrical services, not as a bolt-on. With 18+ years of building services experience across Kenya, Uganda, South Sudan, Seychelles, Rwanda and Mauritius, we understand how solar PV, solar thermal and heat pump technologies interact with HVAC plant, hot water generation, standby generators and the utility supply.
Our approach
Every renewable project starts with the load, not the panel. We analyse your consumption profile — daytime versus night demand, seasonal variation, critical circuits — before recommending a technology mix and system size. Feasibility work includes yield estimation, roof or ground-mount structural review, shading assessment and a tariff-based financial appraisal, so the business case is clear before design begins.
Design then covers the full system: array layout, inverter and battery storage sizing, protection and metering, changeover logic with generators, and integration with hot water plant where solar thermal or heat pumps are the better fit. Because we design the wider MEP services too, renewable plant is coordinated with roof drainage, plant rooms, cable routes and structural allowances from the outset.
What we deliver
Feasibility studies with yield estimates and financial appraisal
Grid-tied, hybrid and off-grid solar PV system design
Solar thermal and heat pump hot water system design
Battery storage and inverter specification
Tender documentation and contractor evaluation
Installation supervision, testing and commissioning
Performance verification and operation and maintenance handover
Engineered with digital tools
We model renewable plant in Autodesk Revit alongside the rest of the building services, which means brackets, cable containment and pipework are clash-checked before installation. Hydraulic analysis in Pipe Flow Expert verifies solar thermal and heat pump circuits, and simulation helps us predict system behaviour before a single component is procured.
Standards and compliance
Systems are designed to recognised international standards, including IEC 62446 principles for the testing, documentation and commissioning of grid-connected PV systems, and are coordinated with local utility and regulatory requirements for grid-tied and net-metered installations. Workmanship on site is supervised against the approved design, with witnessed testing before handover. Performance is then checked against the predicted yield, so any shortfall is found and corrected early rather than discovered on the utility bill.
The result is a renewable energy system that performs as predicted — sized for your actual loads, integrated with your existing plant, and documented so your facilities team can operate it with confidence for years to come.

FAQ
Common Questions
Does solar PV make financial sense for a commercial building in Kenya?
Often, yes — particularly where daytime consumption is high, as in offices, factories, hotels and hospitals. Solar generation then offsets grid purchases directly, without heavy reliance on batteries. Rather than quote generic payback figures, we carry out a site-specific analysis using your actual consumption data, tariff structure and available roof or ground area, so the investment decision rests on real numbers.
Can a solar system run alongside our generator and the grid?
Yes. Hybrid operation is standard in our designs. We engineer the changeover and control logic so the PV system, utility supply and standby generator work together safely — including protection settings that prevent the inverter back-feeding a generator. Battery storage can be added to bridge outages and reduce generator run hours, which cuts fuel costs and maintenance.
Do you install the systems yourselves?
We are the engineers, not the installer. TechMEPi designs the system, prepares tender documentation, helps you evaluate contractors, and then supervises the installation on your behalf. This keeps design intent independent of equipment sales, so the system you get is sized for your loads rather than for a supplier's stock. We witness testing and commissioning before signing off.
What maintenance does a solar PV system need?
Relatively little, but it is not zero. Panels need periodic cleaning — more often in dusty environments — plus inspection of mounting structures, cabling, earthing and inverter performance. Batteries, where fitted, have their own service regime. We provide an operation and maintenance schedule at handover and can recommend a monitoring setup so falling output is spotted early rather than discovered on the bill.
