Home Starter
Keeps lights, WiFi & fridge on for ~3–5 hrs
First-time backup for the essentials — lights, TV, WiFi, and refrigeration basics.
Budgetary range
KSh 180,000 – KSh 325,000
3 kW inverter · 2.5 kWh lithium
Most Popular
Covers most rooms for ~4–8 hrs without the grid
Balanced home backup — runs lighting, TV, fridge, and moderate appliances with strong uptime.
Budgetary range
KSh 250,000 – KSh 410,000
5 kW inverter · 5 kWh lithium
Home Premium
Full home backup including pumps & A/C for ~6–12 hrs
Larger homes needing longer backup windows, pump support, and appliance headroom.
Budgetary range
KSh 470,000 – KSh 820,000
8 kW inverter · 10 kWh lithium
SME / Office
Office continuity for ~4–8 hrs on prioritized loads
Budgetary starting point for office and small commercial backup before site-specific load review.
Budgetary range
KSh 720,000 – KSh 1,370,000
10 kW baseline · 15 kWh lithium
Facilities & Institutions
For factories, schools, clinics, and multi-building sites. These projects require a full engineering scope review, 3-phase load analysis, and a formal Bill of Quantities — no fixed kit price applies until after a site survey.

Start from a plan above or build from scratch. In Simple mode, just pick what you need — we handle the technical sizing. Switch to Advanced if you want to adjust the inverter, battery, or add-ons yourself.
Simple mode auto-sizes technical settings. Switch to Advanced for manual inverter, battery, and extras.
Default uses EPRA domestic retail reference (~KSh 28.7/kWh). Adjust to your actual tariff.
Used only for a budgetary bill-offset estimate. Final savings depend on tariff, usage timing, and site design.
Sizing is based on daily hot-water demand. We confirm after site survey.
Examples only. Actual performance depends on roof orientation, shading, inlet water temperature, demand pattern, and plumbing.
What this powers:
Runtime is estimated from the selected battery size and the profile shown above using duty-adjusted average and busy-use load assumptions, bounded by the selected inverter output.
For SME and institution profiles, the calculator applies diversity/concurrency assumptions so it does not treat all listed categories as running at the same time.
—
Battery-only estimate for the selected profile above. Lower value assumes busier simultaneous use; higher value assumes duty-cycled/typical use. Daytime solar contribution can extend runtime.

Budgetary estimate only. Final savings depend on tariff, daytime self-consumption, shading, roof orientation, inverter settings, and the final engineered design.
*Estimate only. Final BoQ confirmed after site survey.
Final price depends on site-confirmed scope such as roof layout/structure, cable or pipe run lengths, DB and grounding/protection upgrades, access complexity, and the selected equipment capacity/brand tier. This is why the calculator shows a budgetary range rather than one fixed figure.
Typical proposal turnaround: 24–48 business hours after survey.
Short answers for budget planning. Technical definitions and deeper explanations are linked in the Learning Center.
This page gives a budgetary range based on your selected plan or calculator inputs. Final pricing is confirmed after a site survey, load review, and BoQ. See System Sizing 101, the project timeline guide, and the Engineering-led Sizing FAQ note.
Roof structure, cable run lengths, DB condition, grounding requirements, plumbing rework (for water heating), and access constraints can change scope and final cost. Related reading: DB Split & Essential Loads Planning, Solar Water Heating Sizing Basics, and Surge Protection & Protection Scope.
Financing availability depends on partner programs and current lender terms. We confirm options, deposit requirements, and repayment tenure during proposal and partner-lender review. Read Financing & Payment Planning Basics for what to prepare before requesting financing options.
The estimate is designed as a practical starting range and can include common extras through the calculator (for example DB upgrades, surge protection, monitoring, and maintenance options). Final inclusions are listed in your BoQ. See the Detailed BoQ & Proposal FAQ, SLD FAQ, and Surge Protection FAQ.
Typical proposal turnaround is 24–48 business hours after the site survey for standard projects. Complex or institutional sites may need additional engineering review. See the installation timeline guide and Handover Pack Explained for how proposal, engineering review, and delivery documentation fit together.
