The following is how to properly size your solar power system and a guide to most homeowners in understanding quotations provided and their power needs.

Step 1: Assess Your Energy Consumption

Begin by evaluating your energy consumption patterns. Review your electricity bills to determine your average monthly and daily energy usage in kilowatt-hours (kWh). Consider seasonal variations in energy consumption as well.

Step 2: Understand Solar Potential in Kenya

Kenya receives abundant sunlight throughout the year, making it an excellent location for solar energy generation. To assess solar potential, consider factors such as the number of peak sunlight hours per day, shading, and the orientation and tilt of your roof.

Step 3: Calculate Your Solar Power System Size

To calculate the solar power system size you need, divide your daily energy consumption (in kWh) by the average daily sunlight hours in Kenya (approximately 5-6 hours on average). This will give you the system size in kilowatts (kW). Since solar panels are typically sold in wattage, convert kW to watts by multiplying by 1,000.

System Size (kW) = Daily Energy Consumption (kWh) / Average Daily Sunlight Hours System Size (W) = System Size (kW) * 1,000

Step 4: Consider Panel Efficiency and Climate in Kenya while sizing your solar power system in Kenya

Take into account the efficiency of solar panels, typically ranging from 15-22%. Adjust your system size to compensate for panel efficiency and consider the climate in Kenya, as it may affect solar panel performance.

Step 5: Factor in Inverter and System Losses

Incorporate the efficiency of the inverter and account for system losses due to wiring, shading, and other components. Inverters typically operate at 90-95% efficiency, so adjust your system size to accommodate these losses.

Step 6: Evaluate the Need for Battery Storage

If you desire energy storage for use during non-sunlight hours or power outages, consider integrating a battery storage system into your solar power setup. Determine the required battery capacity based on your energy storage needs.

Step 7: Seek Guidance from a Solar Professional

Consult with a solar professional or installer in Kenya to conduct a thorough system sizing assessment. They can provide valuable insights, consider specific regional factors, and offer a precise solar power system recommendation based on your energy requirements and location.

Conclusion on how to size your solar power system in Kenya

Sizing your solar power system in Kenya involves careful consideration of your energy consumption, solar potential, panel efficiency, and system losses. By accurately calculating the system size and seeking expert advice, you can design an efficient solar power system that aligns with Kenya’s abundant sunlight, contributing to a sustainable and energy-independent future.
