How To Calculate a Solar Panel Efficiency

Solar panel efficiency is a measure of how well a panel can convert sunlight into usable electricity. This conversion rate is influenced by several factors. Before we get to the formula, let’s look at what is involved.

Different Solar Cell Materials with credits to

Type of Solar Cell

Solar cells come in various types, with monocrystalline cells leading the pack in efficiency. They’re followed by polycrystalline and thin-film cells. Each type has its unique structure and properties, influencing its ability to convert sunlight. The reference image above is by the Department of Energy, an official government entity.

Material Quality

The quality of materials used in a solar panel play a pivotal role in its performance. Premium materials, like those used by Expert Solar, ensure optimal conversion rates and improved life-spans.

Tampa Solar Panels Getting Sunlight With The Right Orientation

Panel Orientation

For maximum efficiency, solar panels must be oriented to capture the maximum amount of sunlight. In Tampa, this means panels should predominantly face south.

Solar Panel Power Production Math Explained

  1. Solar Panel Rating (in Watts): This is the maximum power a solar panel can produce under ideal sunlight conditions. It’s usually provided by the manufacturer.
  2. Solar Irradiance: This is the amount of sunlight received per square meter. On average, the Earth’s surface receives about 1000W/m^2 of solar irradiance during peak sunlight hours. However, this value can vary based on location, time of year, and atmospheric conditions.

    Reference: Solar and Moon Position Algorithm (SAMPA) – This article discusses the algorithms for calculating the solar zenith and azimuth angles in the period from the year -2000 to 6000, with uncertainties of ᄆ0.0003ᄚ.

  3. Peak Sunlight Hours: This is the number of hours in a day when solar irradiance averages 1000W/m^2. It varies based on location and time of year. For instance, Florida might average around 5.5 peak sunlight hours per day over the course of a year.

    Reference: National Renewable Energy Laboratory (NREL) – NREL provides solar resource data and tools, including maps that show average daily solar potential for different regions.

4. Efficiency of the Solar Panel: Solar panels convert only a fraction of the sunlight they receive into electricity. This efficiency can range from 15% to 22% for most commercial panels.

Reference: Progress in Photovoltaics – This journal often publishes advancements in solar panel efficiency, providing a comprehensive view of the current state of photovoltaic technology.

5. Losses Due to Inefficiencies: No system is perfect. There are losses due to inefficiencies in inverters, temperature losses, and other system inefficiencies. On average, these losses can account for about 20% of the energy produced.

Reference: Energy losses in photovoltaic systems – This paper from the IEEE Xplore digital library discusses the various energy losses in PV systems.

The Equation

Given the factors above, the average daily kWh output of a solar panel can be calculated as:


Average kWh Output = Solar Panel Rating × Peak Sunlight Hours × Efficiency × ( 1 − Losses Due to Inefficiencies )

Average kWh Output = Solar Panel Rating × Peak Sunlight Hours × Efficiency × (1−Losses Due to Inefficiencies)

For a 300W panel in Florida with an efficiency of 18%:

Average kWh Output = 300W × 5.5  hours × 0.18 × 0.8 = 237.6  Wh or 0.2376 kWh

Average kWh Output = 300W × 5.5 hours × 0.18 × 0.8 = 237.6 Wh or 0.2376 kWh

This means, on average, this panel would produce about 0.2376 kWh per day in Florida.
