As the demand for renewable energy continues to rise, many homeowners and businesses in Zimbabwe are turning to solar power as a reliable and sustainable solution. 

However, determining the proper size of a solar system can be a daunting task for many. In this article, we will guide you through the process of sizing a solar system, including the number of solar panels needed, size of batteries, and the inverter.

Step 1: Estimating Your Energy Usage

To begin sizing your solar system, it is important to assess your energy needs. Follow these steps to determine your average electricity consumption:

  1. Calculate your kWh usage: Gather your electric bill and note the kilowatt-hours (kWh) usage. Look at a full 12-month report to identify any peaks and valleys in usage throughout the year.
  2. Figure out your daily kWh usage: Divide your monthly kWh usage by 30 (the number of days in a month) to determine your average daily kWh usage.
  3. Determine your average monthly kWh usage: Add up your kWh usage for 12 months and divide by 12 to find your average monthly consumption. Keep in mind that grid-tied systems tend to overproduce in the summer months due to increased sun exposure.

Step 2: Look Up Your Peak Sun Hours

The average peak sun hours vary depending on your location and local climate. This information is crucial for maximizing the efficiency of your solar power system.

Step 3: Calculate the Size of Your Solar System

To determine the size of your solar system, follow these calculations:
  1. Divide your daily kWh energy requirement by the peak sun hours to get the kW output.
  2. Divide the kW output by your panel's efficiency to estimate the number of solar panels needed for your system.

Step 4: Determining the Estimated Solar System Design

To ensure accuracy in your solar system sizing estimate, consider the following factors:

  1. Select your mount type: A roof mount is the most cost-effective solution. Check if you have any viable north-facing options for a roof mount. If not, consider a rooftop mounting rack or explore ground or pole-mounted solutions.
  2. Consider solar panel size: If you have a small or odd-shaped roof, the size of your solar panels becomes crucial. With a large usable roof area, you can opt for larger panels to meet your energy output. If your usable roof area is limited or partially shaded, fewer smaller high-efficiency panels may be the most cost-effective solution.

Step 5: Choose the Right Solar Panels

When selecting solar panels, take into account your roof size and shape, as well as any shading issues. Additionally, consider the long-term scalability of your system, allowing for future expansion if needed.
