Residential Solar System

Residential Solar Systems for Kenyan Homes

Complete home solar solutions — from solar panel installation and hybrid inverters to lithium battery storage and full off-grid systems. SunPro is Kenya's trusted solar company, serving over 500 families since 2016. We design, supply, and install every component of your residential solar system using genuine Sun King equipment — Africa's leading solar brand, trusted by 1 in 5 Kenyan households. Free site assessment, EPRA licensed installation, and lifetime WhatsApp support.

Why Kenyan Homes Are Switching to Solar

KPLC tariffs have surged by more than 40% over the past three years. The typical Kenyan household now spends between Ksh 3,000 and Ksh 20,000 every month on electricity. Load shedding remains a daily frustration, and generator fuel costs keep rising. Solar solves all three problems at once. A properly designed residential solar system from SunPro eliminates your dependence on the grid during daylight hours, charges batteries for overnight use, and dramatically reduces what you pay KPLC each month. Our customers typically recover their investment within 2 to 4 years — and then enjoy nearly free electricity for decades.

Sun King Solar Panels — The Heart of Your System

Every residential solar system we install uses genuine Sun King monocrystalline panels — Africa's most trusted solar brand.

The Sun King Story

Founded in Nairobi in 2007 by Patrick Walsh and Anish Thakkar, Sun King has grown to become the world's leading off-grid solar brand with over 27 million products sold across Africa and Asia. In 2025, Sun King opened a Nairobi manufacturing plant capable of producing 700,000 units annually. Today, 1 in 5 Kenyan households uses a Sun King product. Their panels deliver up to 24% efficiency with excellent low-light performance, and every panel carries a full 25-year linear performance warranty.

Why Sun King Panels?

Sun King panels are designed and rigorously tested for African conditions — handling intense sun, dust, heat, and humidity that would degrade lesser panels. Available in 450W to 550W ratings, they deliver proven performance and genuine warranty support through Sun King's extensive service network across Kenya.

Why Monocrystalline?

Monocrystalline solar panels are the highest-efficiency photovoltaic technology available. Unlike older polycrystalline panels, monocrystalline cells are cut from a single pure silicon crystal, allowing electrons to flow more freely and achieve higher conversion rates. Tier-1 designation means the manufacturer is bankable with proven global track record — ensuring your warranty is honoured for decades.

Solar Inverters & Battery Storage

The inverter and battery are the heart and brain of your solar system. We supply and install Sun King inverters and lithium batteries — designed and tested for African conditions.

Sun King EBD Series

Affordable hybrid inverters for Kenyan homes. Pure sine wave output, built-in MPPT charge controller, and seamless grid-tie functionality. The most popular choice for budget-conscious homeowners. Available from 1.6kVA to 5kVA.

Complete Off-Grid Solar Systems

For homes beyond the grid or those seeking total energy independence. Every component is carefully matched to deliver reliable power 24/7.

Solar Panels

Sun King monocrystalline panels from 450W to 550W. Off-grid systems require 20-30% additional panel capacity as a safety buffer to generate enough energy for both daily loads AND battery charging.

Off-Grid Inverter

Sun King off-grid inverters manage battery charging and discharge without any grid reference. Pure sine wave with high surge capacity to start motors and pumps. Designed and tested for African conditions.

Battery Bank

Sun King LiFePO4 batteries with 6,000+ cycle life and deep discharge capability. A typical off-grid home needs 5kWh-20kWh of storage. Lodges and farms scale up to 40kWh+ with parallel banks.

Charge Controller

Sun King MPPT charge controllers extract every available watt from your panels, especially during low-light hours. MPPT boosts overall system efficiency by 20-30% compared to older PWM technology.

Generator Backup

Optional automatic generator start for extended cloudy periods. The inverter monitors battery state and auto-starts the generator when needed — typically 50-100 hours per year in most Kenyan climates.

Remote Monitoring

Track solar production, battery state, consumption patterns, and system health from anywhere. Receive alerts if something needs attention — we can diagnose and respond remotely.
