System overview

How a hybrid solar system works

Illustration of how the parts of a system work together: solar array, battery storage, hybrid inverter and grid supply.

A day in a home in Nairobi

Illustration with approximate figures

Modelled from public data: in October, Nairobi averages about 4.5 kWh of solar per kWp each day (Global Solar Atlas), with sunrise near 06:30 and sunset near 18:35. Grid power costs about KES 28 per kWh. Real results depend on roof, weather and habits.

Cloudy

Assumptions behind these figures

From real data

  • Solar yield for Nairobi in October: 4.46 kWh per kWp per day, the Global Solar Atlas long-term average (Solargis satellite data) at the county centre.
  • Today's cloud cover for Nairobi from the OpenWeather forecast, hour by hour (see the hourly table). A clear hour follows a clear-day yield of about 5.9 kWh per kWp, reduced for cloud using the Kasten and Czeplak formula.
  • Sunrise about 06:30 and sunset about 18:35, worked out from Nairobi's longitude. On the equator days last about 12 hours all year.
  • Grid price about KES 28 per kWh (September 2026): the domestic energy charge of KES 18.57 (homes using over 100 kWh a month), about KES 4.16 in monthly pass-through charges, the REP and ERC levies and 16% VAT. Homes pay the same rate at every hour, so the hourly grid cost is simply kWh times that rate.

Assumed

  • Home use follows a typical Kenyan pattern: early-morning and evening peaks and a fridge running all night. Your own bill will differ.
  • Lithium battery kept between 10% and 100%, about 95% efficient each way, used before buying from the grid.
  • The saving counts grid kWh avoided only. Monthly fixed charges and the cost of the system are not included.
Hourly table

Cloud cover is today's OpenWeather forecast for Nairobi. Grid cost is each hour's grid kWh at about KES 28 per kWh.

  • Hadada, Naivasha: Building the Support Behind a 45 kVA Solar System

    At Hadada in Naivasha, Buddy Systems installed a containerised Victron system comprising three 15 kVA Quattro inverter/chargers, two SmartSolar MPPT RS 450/200 charge controllers and 56 solar panels rated at 620 W each, giving a total solar array capacity of 34.72 kWp.

  • BBC East Africa, Karen: Resolving Generator Trips During Battery Charging

    The challenge At BBC East Africa’s Karen facility, a 120 kVA generator was tripping at approximately 21 kW when the Victron inverter/chargers drew power to charge the batteries. The repeated trips interrupted charging and affected coordination between the generator and battery backup system.

  • Small Solar, Big Impact: Powering Wildlife Ranger Outposts

    Small Solar Systems for Wildlife Rangers: Practical Lessons from the Field At a remote ranger outpost, a few lights, charged radios and working phones can make a significant difference. The energy requirement may be modest, but the distance from suppliers and technical support makes careful preparation essential.
