How Many Solar Panels To Run A House

Why Such A Big Range

How Many Solar Panels Are Needed to Run a House?

With both these budget and premium examples, we give a pretty big range in the number of solar panels needed. Why is that?

The main reason is that the amount of electricity that solar panels will generate depends heavily on the amount of sunshine you get in your city. It helps to be further south, but local climate is just as important. There are many dry climates in the northern United States that have higher solar radiation than cloudier cities that are further south. Map of solar radiation in the United States

The ranges we give – between 19 and 30 premium solar panels to generate enough electricity for an average 3,000 square foot house – were calculated based on houses located in the cloudy northwest and the very sunny southwest . These two cities are at opposite ends of the spectrum when it comes to incoming solar radiation, measured as Direct Normal Irradiance.

Most cities in the continental United States lie between these two extremes and receive an average amount of sunlight, making them perfectly viable for home solar. Check out the map above.

    How Many Solar Panels Do I Need For A 2000 Square Foot House

    This is a difficult question to answer without knowing more about the home in question. A few factors that will affect how many solar panels are needed include the direction of the house, its shade, and its insulation. Additionally, the size and type of solar panel will also play a role in how many are needed. A good rule of thumb is that for every kilowatt of energy that a solar panel produces, you will need about 100 square feet of roof space. So, a 2000-square-foot house with 4 kW of solar panels would need 400 square feet of roof space covered in solar panels.

    A solar cell system is no small undertaking and requires a great deal of consideration and planning. One of the biggest questions that homeowners often have is, How many solar panels would it take to run my home on renewable energy? Because every home is slightly different, there is no one cookie-cutter answer to this question.

    Instead, we can look into some of the determining factors for creating solar panel homes. Heres what you should ask to determine how many solar panels it would take to run your home.

    The Falling Price Of Solar Energy

    Currently, solar panels are one of the more easily accessible forms of renewable energy. Solar energy attracts people in large part because of its many benefits, ranging from significant reductions in greenhouse gas emissions to increasing home value by an average of $15,000. With enough panels installed in Texas to power more than 350,000 homes, it is no longer uncommon to see solar panels affixed to the roofs of residential homes and businesses.

    This expansion is also due to the falling price of generating solar electricity. Solar prices in Texas from 2014 to 2019. This decrease is even more dramatic across a longer time frame, as solar panel installation costs in the United States dropped by 70% from 2009 to 2019. In response, demand for residential solar panels and solar power in general has grown tremendously.

    How Many Solar Panels Does My House Need

    To calculate the number of solar panels needed to power your house you need to know following two things.

  • Average monthly power consumption of your house.
  • Average monthly solar power generation at your place.
  • To find your average monthly power consumption of your house, just look into your latest month electricity bill, there you will find your last 12 months power consumption. Add the last 12 month power consumption data and divide it by 12 to get your house average monthly power consumption.

    Once your get your house average power consumption its time to know your average monthly solar power generation. The average monthly solar power generation varies from 80 kWh to 130 kWh.

    I live in Mumbai, India here we get at least 4 5 sun hours everyday for around 300 days in a year.

    The average monthly power produced by a 1 kW solar system in Mumbai, India is around 110 kWh 115 kWh. Let me clarify this value goes up in the summer and comes down in the rainy season so this is just an average value.

    If your state or country receives similar amount of sun hours through out the year then you can assume your localities average monthly solar power generation to be 115 kWh.

    However if you live in cold countries or places where there is less sun hours then dont take this value just google your countries name with monthly solar power generation in the suffix and you will get a figure for your monthly solar power generation.

    How Many Kwh Can Solar Panels Produce And How Many Panels You Need On Your Roof

    The amount of power your solar energy system can produce depends on the number of solar panels that can absorb solar energy and convert it into electricity.

    Assuming you are going to choose standard-efficiency solar panels, here are the most common sizes for residential solar systems and their kWh production potential to give you an idea of how many panels you would need to run a house.

      • A 3kW solar system which consists of 12 panels can produce an average of 4,200 kWh per year. You will need a roof space of about 194 sq ft for a 3kW system.
      • A 5kW solar system which consists of 20 panels can produce an average of 7,000 kWh per year. You will need a roof space of about 340 sq ft for a 5kW system.
      • A 10kW solar system which consists of 40 panels can produce an average of 14,000 kWh per year. You will need a roof space of about 680 sq ft for a 10kW system.

    Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location.

    For example, California has more sunny days annually than Washington. In this case if you live in Washington you would need a bigger solar system to get the same power as you would get with a smaller system in California.
