Generator & Solar Water Pump Price in Kenya 2026: Backup Power for Homes, Shops and Farms

Power cuts stop water pumps, RO plants, vending machines and shops. This guide covers the generators, solar pumps and solar backup kits on Buy More Mall, with prices and a simple way to choose the right size.

How to Size a Generator

1. List what must run at the same time and add up the watts (on the label of each appliance).
2. Allow for starting current. Motors (pumps, fridges, compressors) can draw about 3 times their running power for a moment when they start. Size for the biggest motor starting while everything else runs.
3. Convert to kVA. For most small sets, kW ≈ kVA × 0.8. So a 2.8 kVA set gives roughly 2.2 kW.
4. Add about 20% spare so the generator is not run at full load all the time.

ATS: Automatic Changeover

An ATS (automatic transfer switch) starts the generator and switches the load over when mains power fails, then switches back when it returns. It is ideal for water treatment sites, clinics and shops where nobody is around to switch manually. The DG6000DS diesel generator comes with an ATS.

Solar Water Pumps and Solar Backup

For water pumping on farms and remote sites, solar pumps have no fuel cost and pump most when the sun is strongest, which is when irrigation and livestock need water. Store the water in a tank for the night instead of storing power in batteries.

A solar pump must be sized for the head (height), the daily volume and the solar panels together. Send us the borehole depth and water needs. For tanks, see Water Tank Price in Kenya.

Safety and Regulations

• Never run a generator indoors or in a closed garage. Exhaust carbon monoxide can kill.
• Connect a generator to house wiring only through a proper changeover switch, installed by a licensed electrician, to protect you and Kenya Power line workers.
• In Kenya, solar PV installers must be licensed by EPRA. Ask to see the licence.

How Does a Solar Water Pump Work?

Solar panels turn sunlight into DC electricity. A controller feeds that power to the pump, adjusting the speed as the sunlight changes, and protects the pump (for example from running dry). The pump runs whenever the sun is strong enough, pumping water into a raised tank. Water from the tank then flows to taps or irrigation by gravity, day and night.

Does a Solar Water Pump Need a Battery?

Usually not. The cheapest and longest-lasting way to "store" solar power for water is a storage tank: pump in the day, use the water any time. Batteries add cost and need replacing. A battery or a hybrid (solar plus mains or generator) setup makes sense only when you need pressure at night without a raised tank.

Surface or Submersible Solar Pump?

Check each product page for the pump type and the maximum head (total lift) before you buy.

How to Size a Solar Water Pump

1. Daily water need: litres per day for the home, livestock or irrigation.
2. Total head: the depth to the water level, plus the height up to the tank, plus an allowance for pipe friction.
3. Water source yield: a borehole cannot give more than it refills.

Send these three figures to us through the product page or WhatsApp and we will match a pump and panel set.

How Long Do Solar Water Pumps Last? Are They Worth It?

Solar panels last many years. The pump's life depends on correct sizing and protection: dry running, sand and an undersized cable are the usual causes of early failure. The big saving is that there is no fuel or power bill, so a solar pump is often worth it for farms and homes far from the grid, or where generator fuel is expensive. The trade-off is a higher upfront cost and less water on cloudy days, which a bigger tank evens out.

Frequently Asked Questions

How much is a generator in Kenya?

On Buy More Mall, from KSh 26,100 (1 kVA petrol) to KSh 247,950 (4.5 kVA diesel with ATS).

What size generator do I need for a water pump?

Allow about 3 times the pump running power for starting. A 0.75 kW pump plus a few lights usually needs a 4 to 4.5 kVA set.

How much is a solar water pump in Kenya?

From KSh 18,230 for a DC solar pump to KSh 38,250 for a larger solar pump system. Panels are sized separately.

Petrol or diesel generator?

Petrol sets are cheaper to buy and fine for occasional use. Diesel sets cost more but use less fuel and last longer for frequent or long running.

Prices shown are regular prices on Buy More Mall. Many products are currently on offer, so open the product page to see today's price.

How does a solar water pump work?

Solar panels power the pump through a controller whenever the sun shines, filling a raised tank that feeds water by gravity.

Does a solar water pump need a battery?

Usually not. A storage tank is the cheaper way to store the water pumped during the day.

How long do solar water pumps last?

Many years when correctly sized and protected from dry running and sand. The panels last longest.

Is a solar water pump worth it?

Often yes for farms and off-grid homes: no fuel or power bill, though it costs more upfront.

Can a solar pump work on a cloudy day?

It pumps less on cloudy days and stops at night, so size the tank to carry you through.
