A Homeowner's Guide to Going Solar

Whether you're looking to cut down on electricity costs, lower your carbon footprint, or become less dependent on the grid, now is a great time to explore solar energy. The technology behind solar power might sound technical, but getting panels installed on your home is more straightforward than you might expect. And with a little planning, the long-term benefits can be substantial.

How Solar Energy Works

Solar panels, also known as photovoltaic (PV) systems, generate electricity by capturing sunlight. These panels contain cells that release electrons when exposed to sunlight. That movement creates direct current (DC) electricity, which then passes through an inverter to become alternating current (AC), the type your home uses.

Most homeowners opt for grid-tied systems, which connect to your local utility grid, allowing you to sell excess energy to the power company and potentially earn credits (a setup called net metering). During times when your system isn't generating enough, like at night, you can still draw power from the grid. For extra energy security, some households also install battery backups to store unused solar power for later.

Modern solar panels are built to last 25 to 30 years and require minimal upkeep. A yearly inspection and occasional cleaning is usually enough to keep things running efficiently.

What's in a Home Solar Power System?

A typical residential solar setup includes:

  • Solar panels, usually roof-mounted
  • An inverter to convert DC electricity to AC for household use
  • Mounting hardware to secure and angle the panels correctly
  • Monitoring tools to track energy production and use

Several factors can influence system performance, including the roof direction, sun exposure, and shade from trees or nearby buildings. But a properly sized system can offset 70% to 100% of your energy use. To get a rough estimate of your potential savings and output, you can use tools like the NREL PVWatts Calculator.

Is Solar Right for You?

Solar energy can work for many households, but it's worth taking a closer look at your home, finances, and long-term goals.

Roof and Sunlight

Solar performs best on homes with:

  • South- or west-facing roofs
  • Little to no shade from trees or buildings
  • Roofs in good condition, ideally less than 15 years old

Even if your area gets a lot of cloud cover, today's solar panels can still generate power in diffused light. But if your Austin home's roof isn't a good candidate, community solar programs offer another option: You can subscribe to a shared solar array and receive credits on your utility bill.

Homeownership and Plans

Solar power is ideal for homeowners who plan to stay put for several years. If you're renting or planning to move soon, options like community solar or flexible third-party financing (like leases or PPAs) may be more practical. Some systems can transfer ownership, but it's important to confirm that before you commit.

Energy Bills and Goals

Homes with electric bills over $100 per month are likely to see the most savings. But cost savings aren't the only reason to go solar: It's also a solid choice if you're focused on sustainability, want more control over energy prices, or hope to raise the value of your real estate.

Making Solar Affordable

Installing solar does come with up-front costs, but there are several ways to reduce them:

  • Federal Tax Credit: You may be eligible for a 30% tax credit through 2032.
  • State and Local Incentives: Some areas offer rebates or performance-based rewards.
  • Financing Options : Choose from loans, leases, power purchase agreements (PPAs), or property-assessed clean energy (PACE) programs to finance your solar setup.

Getting Started

When you're ready to add solar power to your home, a little prep work can make the process smoother.

  1. Estimate Your Savings: Use the NREL's PVWatts tool to see what kind of solar output and return you might expect based on your home's roof and local weather.
  2. Explore Financing: Research whether buying, leasing, or using a PPA makes the most sense for your budget and goals.
  3. Boost Efficiency First: Make your home more energy-efficient before installing solar. Simple upgrades like better insulation, high-efficiency appliances, and LED lighting can reduce your overall energy use and allow you to install a smaller (and cheaper) system.
  4. Use a Trusted Installer: When you're ready, find a board-certified professional to install your new system. Be sure to compare quotes and understand any applicable warranties before you sign a contract with your installer.

Glossary of Solar and Renewable Energy Terms

  • Community Solar: A shared system that serves multiple households
  • Inverter: A device that transforms DC solar panel output into AC electricity
  • Net Metering: A utility policy that credits people with solar power when they feed their excess energy into the local power grid
  • Photovoltaic (PV): Technology that converts sunlight directly into electricity
  • Power Purchase Agreement (PPA): A system under which a third party pays for a solar energy setup on your property and then sells you the power it generates
  • Solar Loan/Lease: Financing methods that allow system use without immediate full ownership
  • Sustainable Energy: A broader category than renewable energy that also considers long-term environmental and social impacts of energy generation

Solar Energy for Kids

For adults, solar power is a smart utility option, but for kids, it's a great way to explore science and sustainability. Did you know that the sun gives off more energy in one hour than the whole world uses in a year? Or that solar panels still work on cloudy days? Kids can learn lots of fun facts about the energy we get from the sun, and they can also make a game out of spotting solar panels on homes, streetlights, and even backpacks or toys.

Fun hands-on activities can also bring these ideas to life. Try making a solar oven out of a cardboard box to make s'mores, or track the sun's movement by tracing shadows throughout the day. Older kids might enjoy building a small solar car or creating a colorful poster about how solar energy works. Learning about clean energy early helps kids understand the power of the sun and how we can use it to build a brighter future.
