Built close to the equipment
Technical decisions should still make sense years after commissioning.
OffGrid Sustainable Energy focuses on systems that can be understood, supported and maintained in the environment where they are installed. That starts with the load and site, not with an arbitrary inverter size.
For homes, farms, businesses and institutions, the design process considers daily consumption, peak and surge loads, battery autonomy, system voltage, roof or ground space, protection, cable routing and room for future expansion.
Design principle: understand the operating requirement first, then specify the panels, storage, inverter and protection as one coordinated system.

Built around real usage
Start with the load, location and operating hours
A dependable system is not selected by inverter size alone. We consider daily consumption, peak demand, backup time, roof or ground space, water head and future expansion.
The enhanced engineering workflow also checks system voltage, battery usable capacity, inverter surge performance, cable and protection requirements, solar resource, orientation, shading and the conditions in the equipment room.
From enquiry to commissioned power
A simple process keeps the system scope, specifications and responsibilities clear.
Consultation
Share what you need to power, the location and the required operating or backup hours.
Assessment
We review loads, site constraints, water requirements, autonomy and installation conditions.
Proposal
You receive the recommended system, component specifications, scope and indicative cost.
Installation
The system is installed, protected, tested, commissioned and handed over with guidance.
A solar project should leave you with more than installed equipment.
A well-structured project should make the design logic, equipment selection and handover understandable. These are the project records we want clients to be able to refer back to.
Load Schedule
The appliances or equipment being powered, their wattage, operating hours and priority level.
Sizing Assumptions
Daily energy, peak demand, surge requirement, autonomy, solar resource and system-voltage assumptions.
Component Schedule
The proposed panels, batteries, inverter, protection equipment and major balance-of-system components.
Protection & Wiring Logic
A clear record of DC/AC protection, isolation, earthing, cable routing and major system connections.
Commissioning Record
Key checks completed before handover, including configuration, basic operating tests and system-status verification.
Handover & Support Notes
How to operate the system, what to monitor, routine maintenance considerations and when to request technical support.
Remote & diaspora project desk
Your project in Kenya can remain visible from wherever you are.
For property owners, families and investors who are not always on site, we can structure the work around remote consultation, local verification, a clear system scope and documented installation updates.
Remote Brief
Define the property, energy priorities, location, budget range and the person coordinating on the ground.
Site Assessment
Confirm loads, installation areas, cable routes, roof or ground conditions, water requirements and site constraints.
Design & Scope

Receive progress updates, commissioning information, user guidance and a maintainable project record.
Project visibility
Know what has happened—and what happens next.
For remotely managed work, updates can be organised around clear milestones rather than scattered messages—so scope, approvals, progress and handover remain easy to follow.

Questions that should be answered before equipment is selected
Good solar decisions usually come from clarifying the operating requirement first. These are some of the questions clients commonly need answered.
Start with a load schedule: what you want to power, each item's wattage, how many hours it runs, and which loads must work during an outage. From that we can estimate daily energy, peak demand, battery autonomy, panel capacity and inverter size.
Often yes, but expansion should be considered in the first design. Inverter limits, battery compatibility, MPPT capacity, cable sizing, mounting space and system voltage can all affect how easily a system grows later.
Battery choice depends on budget and application. LiFePO₄ systems generally offer deeper usable capacity, higher cycle life and lower maintenance, while lead-acid options may reduce initial cost. The correct comparison should consider usable energy and expected lifecycle, not only the Ah label.
Many hybrid systems can coordinate solar, batteries and an AC source such as the grid or a generator. The exact configuration depends on the inverter, switching arrangement, charging limits and the operating priority you want.
Yes. A remote project can be structured around a clear brief, local site verification, design approval, documented progress and commissioning information. The key is to agree in advance what will be verified and what evidence is provided at each milestone.
No. Product pricing and availability should be confirmed before purchase, and a complete installation may also require mounting, protection, cabling, transport, labour and site-specific materials. Equipment purchases and complete project quotations are therefore handled separately.
