Who we are

We size it, we install it, and we stand behind it.

Elumina is an off-grid solar company working across all 47 counties. We survey the site, size the system to the load you actually run, install it with our own technicians and commission it against a metered output figure you can hold us to. One company handles the whole job, and one quoted price covers it.

We were started for a straightforward reason. Kenyan households and small businesses are paying more than KSh 27 for every unit of grid electricity once EPRA's levies and VAT are counted[1], and they are paying it forever. A solar system costs roughly two years of that bill and then stops costing anything. The maths has worked for years. What has been missing is a company that quotes an honest total, turns up when it says it will, and is still answering the phone in year three.

Our mission

To make owning your own power supply cheaper than renting it — and to be the solar company Kenyans recommend to their neighbours.

One price, in writing

Installation, switchgear and commissioning are in the quoted figure. Nothing is added on the day.

A guarantee that costs us something

We commission against a metered output figure. If the system misses it, we fix it at our expense.

We answer in 24 hours

Faults acknowledged within a day and attended within three. In writing, in your contract.

Financing without a bank

In-house terms of 12, 24 or 36 months. No collateral beyond the system itself.

Advanced — adjust the assumptions

The default tariff of KSh 32.20 is our estimate of the all-in cost per unit on the Domestic High-Consumption band (over 100 units a month), including the energy charge, fuel and forex adjustments, REP and EPRA levies and 16% VAT. EPRA revises the pass-through components monthly, so your own rate will differ — divide your last bill by the units on it and enter that figure for an accurate result.[1]

Why solar, why now

Three reasons Kenya is switching

Kenya sits on one of the better solar resources in the world — roughly five peak sun hours a day, year round, with almost no seasonal collapse.[3]

Your bill only moves one way

Every unit you generate is a unit you don't buy. In August 2026 alone EPRA added KSh 4.70 to every unit — a 17% rise in a single month.[2] Pass-throughs are revised monthly and are not frozen.

508 unitsa 10 kWh system generates in a typical month

The lights stay on

Grid interruptions are a normal part of operating in Kenya, and for a shop or salon every hour dark is an hour of lost trade. Your system carries the premises straight through — no generator, no fuel queue, no noise.

0 secondschangeover. Most customers never notice the grid has gone

You own it. You're not renting it

Every shilling paid to Kenya Power is gone for good. A solar system is an asset on your roof that stays with the property when you sell — and stops being a cost the day it's paid off.

The process

How it works

Four steps. Most customers are generating their own power within a week of saying yes.

1

Free consultation

Send us your last Kenya Power bill on WhatsApp. We tell you what you'd save in shillings — on your consumption, not an average.

2

Custom design

We survey your roof and size the system to your actual load. You get a written quote with every component itemised and nothing hidden.

3

Professional installation

Our own technician installs, commissions and tests the system. One day on site, within five working days of payment.

4

Instant savings

Your system starts generating the day it's commissioned. The difference shows on your very next bill.

Transparent pricing

Systems and pricing

Every price includes supply, installation, commissioning and the changeover switch. Solar equipment is VAT-exempt in Kenya, so there is no VAT to add.[4] Transport and travel outside Nairobi are quoted separately once we know the site — we tell you the figure at survey, never after.

Plain-English glossary

kW vs kWhA kW is how fast you can use power; a kWh (a "unit") is how much you used. A 6 kW inverter is the tap; a 10 kWh battery is the tank.
Off-gridThe system runs your property independently of Kenya Power, storing daytime generation in a battery for use at night.
LiFePO₄Lithium iron phosphate — the battery chemistry we use. Safer and far longer-lived than lead-acid, with no maintenance.
Charge cycleOne full discharge and recharge. A 6,000-cycle battery lasts over sixteen years at one cycle a day.
Peak sun hoursThe number of hours a day the sun delivers full-strength output. Kenya averages about five.[3]
Depth of dischargeHow much of a battery you can safely use. Lead-acid gives you about half its rating; LiFePO₄ gives you nearly all of it.
Hybrid inverterConverts DC from the panels to AC for your sockets, and manages the battery and grid at the same time.
Changeover switchSafely isolates your system from the grid. Legally required, and frequently missing from cheap quotes.
Answers

Questions people ask before buying

Is rooftop solar actually worth the investment?+

If your Kenya Power bill is above roughly KSh 6,700 a month, yes — and it is not a close call. At KSh 32.20 a unit,[1] a 10 kWh system costing KSh 429,000 offsets about KSh 16,358 of bill a month. That returns the purchase price in around two years, and over ten years it returns roughly KSh 2.5 million against a KSh 429,000 outlay.

Below about KSh 6,700 a month it is not worth it, and we will tell you so rather than sell you one. Our smallest system generates around 254 units; if you only use 250 you are paying for capacity you cannot use, the payback stretches past four years, and your money is better spent elsewhere until your consumption rises. The calculator on this page applies that test automatically and will say so on screen.

The other half of the answer is not financial. A system that carries your premises through an outage is worth something separate from the bill it saves — and for a shop or a clinic, usually more.

How much can I really save every month?+

Between about KSh 6,700 and KSh 24,500 a month depending on system size. But the honest answer is that it depends on when you use power, not only how much.

Daytime consumption comes straight off the panels. Everything after dark has to pass through the battery, and the battery holds less than a day's generation. A shop trading from 7am to 9pm will reach the figures above. A household that uses most of its power between 7pm and 11pm will see less, because the battery caps what can be delivered overnight.

That is why our survey asks how your day actually runs, and why we size against your load rather than your bill. Two houses with identical bills can genuinely need different systems. Our estimates also cap the saving at 90% of your consumption — no off-grid system offsets every unit, and any quotation showing a zero bill is not being straight with you.

I can't pay KSh 429,000 upfront. What are my options?+

Most of our customers don't pay upfront. We finance in-house, so there's no bank, no collateral beyond the system itself, and a decision in days rather than weeks.

You choose the term: 12 months for the lowest total cost, 24 months (our standard), or 36 months for the lowest monthly payment. Deposits run from 25% to 40% depending on the term.

On the 36-month plan a 10 kWh system costs KSh 10,750 a month against roughly KSh 16,358 of Kenya Power bill it replaces — so the system more than covers its own payment while you own it outright at the end. On the 24-month plan the payment of KSh 17,017 sits about level with the saving: you break even monthly and own the asset two years sooner.

We'll ask for six months of M-Pesa statements and twelve months of KPLC bills to confirm affordability. Use the calculator to see all three terms against your own bill.

Will solar work on my home's roof?+

Almost certainly. Four things decide it, and we check all four at the free survey.

Space. Each panel is about 2.7 m². A 5 kWh system needs roughly 13 m² of clear roof, a 10 kWh system about 26 m², and a 15 kWh system about 39 m² once access gaps are allowed for. Most three-bedroom homes have more than enough on one pitch.

Direction and pitch. Near the equator orientation matters far less than it does in Europe. South, north, east or west all work in Kenya; a flat roof is fine and we add a tilt frame so rain washes the panels rather than pooling dust on them.

Shade. This is the one that actually stops jobs. A tree or a neighbouring wall shading part of the array for a few hours cuts output disproportionately, because the shaded panel drags its whole string down. We assess it at survey and design around it.

Structure. Panels and mounting add roughly 15 kg per square metre — light for mabati on purlins, tile, or concrete. We fix through the sheet into the purlin, never into the sheet alone. If a roof is not sound we will say so before you spend anything.

Does it generate electricity during cloudy or rainy days?+

Yes, but less. Panels work on daylight rather than direct sun, so on a heavily overcast day you can expect roughly 10–25% of clear-sky output. Light rain actually helps a little afterwards, because it washes dust off the glass.

Kenya's advantage is consistency. The country averages around five peak sun hours a day with far less seasonal swing than most of the world.[3] We design against the cloudiest month rather than the annual average, so a well-sized system carries a bad week rather than collapsing in it.

When the battery does run low, the inverter draws from Kenya Power automatically and you keep going — you simply pay for those units. That is why our estimates show a small residual bill rather than zero. Persistent shortfall means the system was undersized at survey, which is our responsibility to fix under the written performance guarantee, not yours to live with.

Do I need batteries?+

If you want the lights to stay on during an outage, yes. A grid-tied system without storage shuts down the moment the grid does — that is a mandatory safety feature, not a fault, and it surprises people who assumed solar meant backup.

If you have no grid connection at all, the battery is the system. Everything after sunset comes from it.

If you are grid-connected, use most of your power in daylight and do not care about outages, then a system without storage is cheaper and worth discussing. Kenya does have net metering for domestic systems up to 10 kW, so exported units earn credits — but those credits are at the avoided-cost rate rather than the retail tariff you pay, and unused credits expire at year end.[6] That maths favours storing and using your own power over exporting it, which is why we quote storage as standard.

The battery is also the most expensive part of the system, so this is a question worth answering honestly at survey rather than assuming.

How long does a solar system last?+

Panels: 25 to 30 years. They carry a 20-year performance warranty and a 12-year product warranty, and they degrade slowly rather than failing — roughly 0.5% of output a year after the first. The panels on your roof will very likely outlast the mortgage.

Battery: 6,000 charge cycles, which is over sixteen years at one cycle a day, with a five-year warranty. LiFePO₄ loses capacity gradually; it does not stop one morning.

Inverter: eight to twelve years, with a two-year warranty. This is the honest weak point — it is the one component you should expect to replace once during the life of the system, and you should budget for it. Anyone who tells you a solar system is entirely maintenance-free for twenty-five years has not owned one.

Over a 25-year life you are looking at one inverter replacement, possibly one battery replacement around year sixteen, and cleaning two or three times a year. Against a Kenya Power bill that never ends, that is still the cheaper side of the trade.

How long does installation take, and how disruptive is it?+

One day on site for most homes and small businesses, and we complete within five working days of payment or deposit, subject to your roof being ready.

Your power stays on throughout. The final changeover takes minutes, and we test the system with you before we leave — including a metered reading against the output we quoted, which becomes the baseline for your performance guarantee.

Larger 15 kWh installations occasionally run into a second day. We'll tell you which applies at the survey, not on the day.

Will the panels damage my roof? What maintenance is involved?+

Panels mount on an aluminium rail system fixed through the roof sheet into the purlin, and every penetration is sealed with EPDM or butyl. We photograph each fixing point and hand you the record. Our workmanship warranty covers the installation, including any leak traced to our fixings, for two years.

Maintenance is minimal: rinse the panels two or three times a year in the dry season, and nothing else. There are no moving parts and no fuel. The lithium battery is rated for 6,000 charge cycles — over sixteen years at one cycle a day — and carries a five-year warranty.

We also offer an annual maintenance contract covering inspection, cleaning and priority callout. Your first year is included free.

What warranty do I actually get, and who honours it?+

Panels: 20-year performance warranty, 12-year product warranty, manufacturer-backed. Battery: 5 years, rated 6,000 cycles. Inverter: 2 years. Our workmanship: 2 years, covering the installation itself.

We hold the manufacturer documentation and handle claims for you, rather than leaving you to chase a manufacturer yourself. You get the full warranty pack, in writing, at commissioning — ask any competitor for theirs before you sign anything.

Do you service systems installed by someone else?+

Yes, after an inspection. We'll assess the installation, tell you honestly what is wrong with it, and quote for repair or for taking it onto a maintenance contract. If the system is unsafe we will say so and we won't cover it.

We do this because a poorly installed system that fails costs the whole industry credibility. Send us photos on WhatsApp to start.
