Solar cooling

Cool your space on sunshine by day, the grid by night.

Hybrid solar air conditioners run directly off solar panels during the day and seamlessly switch between solar, grid, or both. No additional batteries, separate inverter or complex wiring required. In good sun they can cut cooling electricity by 60–90%.

What it is

The idea, plainly

A DC-inverter air conditioner wired to work on solar DC, grid AC, or a mix of the two. It prioritises free solar power whenever it's available and draws from the grid only to make up the difference — automatically.

How it works

  1. 01

    DC only — strong sun runs the unit entirely on solar, even off-grid.

  2. 02

    AC + DC — weaker sun uses solar first and tops up from the grid.

  3. 03

    AC only — at night it runs like an efficient inverter air conditioner.

  4. 04

    It balances the two sources automatically, with app control and metering.

The payoff

What you get

For your home

  • 60–90% less cooling electricity in good sunshine
  • No battery bank and no extra inverter to buy or maintain
  • Cool rooms during the day even when the grid is down
  • Smart-app control with solar and grid power metering

For business & institutions

  • Cuts daytime cooling costs where demand and sun peak together
  • Ideal for offices, shops, clinics and classrooms
  • Plug-and-play — no battery infrastructure to house or service
  • Wide operating range for Kenya's varied climates
