How Much Solar Power Can My Roof Generate?

April 5, 2022

While solar energy seems to be a great long-term solution for cutting electricity costs in most homes, one of the main concerns many people often have about solar panels is the amount of power they can generate every day. However, there is no one-size-fits-all type of answer as many factors can affect solar production. This article will help answer questions about solar power generation to help you choose and install solar panels that suit your needs.

What Factors Affect the Amount of Energy That Solar Panels Can Produce?

While it’s typically a significant focus, sunlight is not the only factor you have to worry about when it comes to solar energy production. Here are other factors to consider when assessing solar panel energy production.

  •         Dirt, leaves, bird droppings, and other debris
  •         Roof angle and direction
  •         The amount of shade
  •         Location
  •         Time of the year
  •         Age of the solar panel
  •         Solar panel size and type

 How Much Energy Can a Solar Panel Generate?

Solar panels are rated based on the watts they generate. Most residential solar panels are designed to generate between 250 and 400 watts each, per hour. To get a clear picture of how much energy your solar panel can produce, you need to consider the type of solar panel and the type of technology used to generate power. As we have discussed above, solar energy production can be affected by many factors. That means we need an ideal situation to help calculate the amount of energy your solar can generate.

For instance, if you live in an area that receives plenty of sunshine, like Scottsdale, AZ, you’re probably getting at least seven hours of direct sunlight every day. Assuming your solar panel is a premium type that generates 400 watts per hour, you will be producing 7 hours x 400 watts = 2800 watts- hours or 2.8kWh per day. That would translate to 2.8kWh x30 = 84kWh per month.

Can Solar Panels Provide Value to My Home?

By now, you probably have an idea of how much energy your solar panel can generate every day. You also know the factors affecting solar production, which mainly boils down to sunlight. Suppose you live in relatively warm areas that receive plenty of sunlight, like Arizona or California. In that case, you’re likely to benefit from solar energy more than people who live in colder climates or regions with less sunlight, like Alaska and North Dakota.

The truth is, it’s possible to fully power your home with solar, but that will require installing many panels to meet your needs. An average home using 11,000kWh per year will typically require about 20 to 25 solar panels of 300 to 350 watts each to be fully powered. Of course, this is just an estimate. The numbers will vary from one home to another based on energy consumption, budget, type of solar panel, and where you live.
