How do you power your house with solar energy?

Harness the power of the sun and learn how to energize your home with solar panels. Solar projects have made it easier for Americans to choose solar energy to power their homes. Solar Energy Technologies Office (SETO) investments have significantly reduced the cost of going solar over the years. There are two primary technologies for harnessing solar power: photovoltaics (PV) and concentrating solar power (CSP). PV panels absorb photons from sunlight to create an electric field and generate electricity. CSP, used in large power plants, concentrates sunlight onto receivers to produce heat and then convert it to electricity.

Key Takeaways:

  • Solar panels can power your home using the energy from the sun.
  • SETO investments have made going solar more affordable.
  • Photovoltaics (PV) and concentrating solar power (CSP) are the primary technologies used.
  • PV panels generate electricity by absorbing photons from sunlight.
  • CSP plants concentrate sunlight to produce heat and then convert it to electricity.

Is my home suitable for solar panels?


Solar panels are a viable option for homes in all climates. However, there are certain factors to consider before deciding if your home is suitable for rooftop solar panels. Excessive shade from trees, as well as an unsuitable size, shape, or slope of your roof, may affect the efficiency of solar systems.

If your roof is not ideal for solar panel installation, don’t worry! You can still enjoy the benefits of solar energy through community solar projects.

Community solar allows multiple individuals to share the advantages and costs of a solar array. This means you can benefit from solar energy without having to install panels on your own roof. You can join a community solar project in your area and contribute to renewable energy generation.

How much power can I generate with solar?

If you’re considering installing a solar energy system, you may be wondering how much power it can generate. Luckily, there’s a tool that can help you estimate the energy production and cost of your solar installation: PVWatts.

PVWatts is a resource provided by the National Renewable Energy Laboratory (NREL) that allows homeowners, solar installers, and manufacturers to estimate the performance and cost of grid-connected PV energy systems. By inputting specific details about your location, system size, and other factors, PVWatts can provide you with valuable insights into the potential energy production of your solar panel system.

Estimating energy production with PVWatts

The PVWatts tool takes into account various parameters to estimate your system’s energy production. These parameters include:

  • The location of your solar energy system, including latitude and longitude
  • The tilt and azimuth of your panels
  • The size of your system in kilowatts (kW)
  • The type of PV module being used

By inputting these parameters, PVWatts can generate an estimate of the energy production and cost of your solar panel system over a specified period, typically a year.

Example: Average system size in Austin, Texas

To give you an idea of what to expect, the average system size for analysis in PVWatts is 7.15 kW. This size is estimated to meet the energy needs of an average home in Austin, Texas.

Keep in mind that this is just an average and the actual energy production of your system may vary based on various factors, such as local weather conditions, shading, and system efficiency.

If you want a more accurate estimate tailored to your specific needs and location, consulting with a solar installer is recommended. A professional solar installer can assess your property, consider additional factors, and provide you with a custom estimate of the power generation potential of your solar energy system.

Now that you have a better understanding of how much power you can generate with solar, you can make more informed decisions about your solar installation and enjoy the benefits of renewable energy.

Will I Save Money by Going Solar?

One of the key benefits of going solar is the potential to save money on your electricity bills. The amount of money you can save with solar depends on various factors, including your electricity consumption, the size of your solar energy system, the purchase or lease options you choose, and the utility compensation for excess solar energy.

Solar prices have been consistently dropping since 2009, making solar increasingly cost-competitive with utility electricity in some cities. This means that switching to solar can help you reduce your reliance on expensive grid electricity and alleviate the burden of rising electricity rates.

Moreover, the soft costs associated with solar installation, such as permitting and inspection, have also decreased over the years. This makes the overall cost of adopting solar technology more affordable and accessible to homeowners.

Another way to boost your savings with solar is to combine it with energy efficiency upgrades. By making your home more energy-efficient, you can reduce the amount of solar power needed to meet your electricity needs. This synergy between energy efficiency and solar energy can lead to even greater long-term savings.

Estimated Savings from Solar Energy

Factors Potential Impact on Savings
Electricity consumption Higher consumption can lead to greater savings
System size A larger solar energy system can generate more electricity, resulting in higher potential savings
Purchase/lease options Choosing the right financing option can impact your upfront costs and long-term savings
Utility compensation Incentives and compensation for excess solar energy can further enhance your savings

Ultimately, the financial benefits of going solar can vary depending on your specific circumstances. To get a clearer picture of the potential savings and return on investment for your solar energy system, it’s recommended to consult with a trusted solar installer or professional who can provide personalized estimates and guidance.

By harnessing the power of solar energy, you can not only reduce your reliance on traditional electricity sources but also take advantage of long-term savings. The combination of lower solar prices, decreased installation costs, and energy efficiency upgrades makes this an opportune time to invest in a solar energy system for your home.
