What is so important about solar panel energy production? Over the past years, solar energy has grown in popularity due to its environmental features and long-term savings. When considering having solar panels installed for your home, it’s natural to think about the amount of energy it produces. Not everyone knows the answer to this, which is why we are going to dive deeper into that to guarantee that you are making the right decision.

What You Should Know About Solar Panel Energy Production

In this article, we will share more about solar panel energy production for residential properties:

1. How Do Solar Panels Work?

Before we get to specific amounts of solar panel energy production, it’s essential first to understand how solar panels work. Solar panels are made of silicon, which collects photons and turns them into Direct Current (DC) electricity. However, DC electricity can only power small devices like phones and flashlights.

For the home, Alternating Current (AC) electricity is needed, which is why home solar energy systems require an inverter that can transform the DC electricity into AC power.

There are a number of factors that affect solar panel efficiency, however, advancements in panel technology have enabled significant improvements over time. Factors like temperature and weather impact the amount of power that can be converted to power for your home, in addition to the materials and processes involved in light capture and energy conversion.

2. How Much Power Solar Panels Produce?

The efficiency of solar panels is often marked by the amount of DC power generated in standard test conditions. The standard test condition is when 1000 megajoules of solar radiation lands on the solar panel as a result of a temperature of 77 °F.

Solar panels are either 260 to 330 watts with 60 solar cells collocated. With that, the higher the wattage of the panels, the more electricity it will produce. This is also why the installation process is crucial and why they must be installed on the rooftop. In that case, 60-cell solar panels are commonly used because they’re more power-efficient.

Similarly, it’s essential to keep in mind that certain factors affect the amount of electricity produced by a single solar panel, including the characteristics of the solar panel and the amount of access to solar irradiation the panel has where it is installed.

3. How Many Solar Panels Do You Need?

By now, you should be aware that you need to purchase a certain number of solar panels to get the amount of energy you need to power up your house. Here are some of the household energy consumers that provides what a look at typical residential electricity consumption in the US looks like:

  • Lighting – 4%
  • Space heating – 15%
  • Water heating – 12%
  • AC system – 16%
  • Refrigerators – 6%
  • TV and other devices -4%
  • Clothes drier – 5%
  • Other devices used for cooking and others – 31%

Based on the numbers provided, you must consider your residential requirements and the climate in your area to ensure you get the right solar

panel type as well as the quantity.

Most of the panels used in residential properties are made of monocrystalline or polycrystalline solar cells. Monocrystalline solar panels are indeed more efficient than polycrystalline panels, but there is only a 5% difference in size. Furthermore, a solar panel’s standard size is around 39 inches wide and 65 inches high.


At this point, you now have a broader understanding of the potential solar panel energy production for your home. However, keep in mind that solar panel efficiency must be considered when rating the panel’s wattage and output. For this reason, to get the most out of your solar panels, make sure you get your solar panels from a reliable company.
