Committing to a solar system is a significant decision, and a lot of the hesitation we hear from clients isn’t really about the technology — it’s about not knowing what the process actually looks like. How long does it take? What do you need to prepare? Will your household or business be disrupted for days? Here’s exactly what happens, from your first call to the day your system is switched on.
Step 1: Initial Conversation
It starts with a phone call, WhatsApp message, or a form on our site — you tell us roughly what you’re trying to solve: reducing a KPLC bill, replacing a generator, backup for regular outages, or powering a specific need like a farm, business, or new property. This isn’t a sales pitch, it’s a genuine scoping conversation. We’ll ask a few questions about your property, current electricity situation, and what matters most to you, and give you an honest initial sense of what’s realistic before booking anything further.

Step 2: Free Site Assessment
This is where the real technical work begins, and it’s genuinely free with no obligation to proceed afterward. Our technician visits your property to assess roof condition, orientation and available space (or ground-mount options if relevant), review your actual electricity consumption — ideally with a recent KPLC bill or generator fuel spend in hand — identify which appliances and loads matter most to you, and check your existing electrical setup for compatibility. For farm, commercial or industrial sites, this assessment goes deeper, covering specific equipment, usage patterns, and any critical loads that need guaranteed backup.
This step is what separates an accurate system design from a generic estimate — everything downstream depends on what we learn here.
Step 3: System Design and Written Quotation
Based on the site assessment, we design a system specifically sized to your actual needs — not a standard package pulled off a shelf. You’ll receive a written, itemised quotation covering exactly what’s included: panel brand and quantity, inverter model and capacity, battery type and size, mounting hardware, cabling, and installation labour, broken out clearly rather than bundled into one number. This typically arrives within a day or two of your site visit, giving you time to review, ask questions, or compare against other quotes with a clear, apples-to-apples specification in hand.
Step 4: Confirmation and Scheduling
Once you approve the quotation, we schedule your installation date and confirm any preparation needed on your end — usually minimal, but for larger commercial or industrial projects, this might include coordinating site access or brief planned downtime. Payment terms are agreed at this stage, and if you’re financing through a bank or sacco, we’re available to support that process with the technical documentation your lender needs.
Step 5: Installation
Installation day itself varies by system size and complexity. A standard residential hybrid system is typically completed within a single day — panels mounted, inverter and battery installed, wiring run and connected, and the system tested before our team leaves. Larger residential, commercial or farm systems may take several days, particularly where additional civil work (mounting structures, trenching for cabling, or three-phase integration) is involved. Our team keeps you informed of progress throughout, and disruption to your property or business is kept to a minimum — this is routine, professional work, not a construction project that upends your daily life.
Step 6: Commissioning and Testing
Before we consider the job complete, the system is fully tested under real operating conditions — confirming panels are generating as expected, the battery is charging and discharging correctly, and (for hybrid systems) that the switch between grid, solar and battery power happens automatically and smoothly. For systems with app-based monitoring, this is also when your monitoring account is set up and connected.
Step 7: Handover and Training
We don’t consider a system delivered until you understand how to use it. This means a walkthrough of your specific system — how to read your monitoring app, what to do (and who to call) if something seems off, basic maintenance expectations like panel cleaning frequency, and where your warranty documentation is kept. You leave this step with a working system and the knowledge to use it confidently, not just equipment on your roof.
Step 8: Ongoing Support
The relationship doesn’t end at handover. You have a direct line to our team for any questions, faults, or maintenance needs going forward, backed by manufacturer warranties on genuine components and our own workmanship warranty on the installation itself. Whether that’s a routine cleaning and check-up, a warranty claim, or simply a question about your system months down the line, the same team that installed your system remains available to support it.
How Long Does the Whole Process Take?
From your first call to a completed, handed-over residential system, the typical timeline runs a week or two — a few days between initial contact and site assessment, a day or two for your quotation, then scheduling and installation itself, often completed within a single day for standard residential systems. Larger commercial, industrial or farm projects take longer given their scope, but follow the same structured process throughout.
Frequently Asked Questions
Do I need to be present for the site assessment? It’s helpful but not always strictly necessary — someone with knowledge of the property and, ideally, a recent electricity bill on hand makes the assessment most accurate.
Is there any disruption to my home or business during installation? Minimal for most residential and small commercial installations — typically completed in a day with limited disruption. Larger projects involving civil work may have more visible activity, which we’ll walk you through in advance.
What if I’m not satisfied with the quotation? There’s no obligation to proceed after a free site assessment — you’re welcome to compare it against other quotes or simply take time to decide.
What happens if something goes wrong after installation? Contact us directly — our team handles diagnosis and, where applicable, manages warranty claims on your behalf, rather than leaving you to navigate a manufacturer’s process alone.
