ABOUT DIASPORA SOLAR
Solar Energy Solutions & Training Built for Africa
Who We Are
A Team of Renewable Energy Specialists
Focused on delivering practical, field-tested solar solutions across residential, commercial and community installations.
Solar PV Design & Installation
End-to-end system design from load analysis through to installation and commissioning.
Battery Storage Solutions
Lithium-ion and lead-acid systems — properly sized for your daily energy needs and discharge requirements.
Inverter Sizing & Optimisation
Matching inverter capacity to continuous and surge loads — pure sine wave systems for sensitive equipment.
Technical Training
Practical solar energy training that equips individuals and teams with real-world installation and design skills.
Energy Efficiency & Load Analysis
Accurate energy consumption modelling to right-size your system and reduce unnecessary costs.
Our Expertise
Deep Knowledge Across Every Layer of Solar
Solar System Design
Load analysis, energy consumption modelling, system voltage selection (12V / 24V / 48V), and performance optimisation — ensuring every system is right-sized from the start.
Battery & Energy Storage
Lithium-ion batteries are safer, lighter, and longer-lasting than traditional lead-acid alternatives. We help you choose the right chemistry for deep-cycle applications, factoring in lifecycle performance and total cost of ownership.
Inverter & Power Systems
Sizing inverters for both continuous and surge power requirements, selecting pure sine wave inverters for sensitive electronics, and accounting for motor startup loads to avoid under-specified systems.
Training & Education
Knowledge is the Foundation of Every Successful Installation
Our training programmes equip individuals and teams with real-world skills to design, size, install and maintain off-grid solar systems.
Solar PV Technical Training
From panel types to roof mounting and MC4 wiring — hands-on from day one.
Battery & Energy Storage
Chemistry selection, sizing, charging profiles and safe handling of lithium and lead-acid systems.
Renewable Energy Systems Design
Full system design from load audit to final component list using the Solar Prescription Method.
Hands-On Practical Learning
Live sessions with Maina Mumbi — real calculations, real questions, real systems.
