The Ultimate Guide to Home Solar Installation

Home Solar Installation

More and more people have turned to home solar installation—in fact, as of 2018, there were 62.4 gigawatts (GW) of installed solar in the United States alone. Whether looking to reduce your carbon footprint or your electricity bill, installing a home solar panel system can prove worth the energy. Looking for a quick and easy guide to home solar installation, ways to decrease your energy use, and everything in between? You’re in luck. We’re here with a handy guide and FAQ to answer your burning questions.

Home Solar Installation: The Way Solar Power Works

What’s in a name? A lot when it comes to solar power. Naturally, solar power uses sunlight by changing it into electricity. Some solar power uses photovoltaics, or PV, to directly convert energy. Others, however, use concentrated solar power, which converts sunlight indirectly. The systems that combine PV and concentrated solar power are called hybrid systems.

The home solar installation incorporates PV solar panels to generate electricity by converting sunlight with the photovoltaic effect. During this chemical effect, material that has been exposed to light creates some voltage and electric current. Homes that install solar power can potentially decrease their electric bills by generating and storing their own electricity.

Many people ask, “what is clean energy?” Well, solar happens to be one of the most popular clean energy sources, as it does not cause any emissions.

Cut Your Spending

There’s no one-size-fits-all way to curb electric bills, but there are a variety of options out there for shrewd homeowners looking to lower their monthly bills. Those looking to make easy changes may use the cold laundry when doing laundry, switch out lightbulbs, and unplug electronics when they’re not being used.

These and other fixes can decrease electric bills, but may not result in the big savings people are looking for. Although home solar installation isn’t for everyone, it can have big advantages for homeowners in the long-run. The average lifetime savings in California from solar power is $73,714, after repayment. On average, the system is fully paid off in just over five years. For Californians who undergo home solar installation, cash flow approximately doubles every five years.

Not only can solar power potentially cover 100% of daily energy usage, in many states costs of installation can be partially offset by incentives and tax credits.

Solar Incentives, Tax Credits, and More!

If you are serious about home solar installation, you should check whether your state offers any tax credits or solar incentives to people choosing to go solar. For example, in California, there are a number of options. Two of the most notable are:

  • Net metering
  • Federal solar tax credit

With net metering, Californians are able to essentially sell additional energy back to the utility company. In 1996, the California Public Utilities Commission started requiring utility companies to offer one-to-one net metering, meaning that if you personally send any unit of energy back into the grid, you receive its full retail value.

The federal solar tax credit in California is commonly known as the solar Investment Tax Credit or ITC. With the ITC, 26% of the total cost of qualified solar installations is credited back to the homeowner. For a system that costs $20,000, the tax credit back would be $5,200. That’s not chump change.

Of course, even with net metering and tax credits, many cannot afford home solar installation outright. These people may be interested to learn about loan programs and payment plans. Although some companies offer these themselves, your state may offer its own, as well. For example, people living in California can use a Property Assessed Clean Energy (PACE) loan program. With this program, the loan is attached to the property where the home solar installation is completed. Therefore, if you use this loan and then move, you aren’t stuck paying off the loan on the system.

Additionally, your state may offer tax exemptions to those who install solar power residentially. Homeowners in California have 100% of the assessed value of their solar systems exempted from property taxes because of the Property Tax Exclusion for Solar Energy Systems.

No two states are alike, of course. It’s important to do your own research on the options available both federally and locally according to your state, city, or county. It is a good idea to check whether the manufacturer or installer of your residential solar system allows customers to pay in installments or provides any bulk discounts or loans.

Size Does Matter

Each home is different, so it’s crucial to evaluate your house before you plan a home solar installation. Solar panels use direct and scattered light from the sun to generate electricity. In general, homes in the US have plenty of exposure to ensure success. On an individual basis, however, results may vary.

You can use several calculators available online to get a good idea of your home’s solar potential. The angle of the roof, exposure to the sun, proximity to tree cover, and the age of your roof can all play a role in whether the home solar installation is a good option for you and your energy needs. When in doubt, turn to trusted contractors who can evaluate your home and determine its solar potential.

They are trained to recognize whether a roof can sustain solar panels if the roof is in good enough condition to last the entirety of the system’s life, and what the appropriate size is for your home’s system. Although the average number of panels needed in the US is 16, this figure can vary. Keep a record of your annual energy use and mention any planned changes during your consultation, as well.

Find a Solar Installation Company You Trust

Although some people choose to personally complete their home solar installation, almost everyone can benefit from speaking with a professional to assess the options available. It is crucial to make sure the installer you speak with is qualified. They should be certified by the North American Board of Certified Energy Practitioners, and come recommended by friends, family, neighbors, and online reviews alike.

When you meet with any company, ask:

  • Do you know local permits and interconnection processes?
  • Can you provide references?
  • Are you properly certified?
  • What is the system’s warranty?
  • Are there any pending or active judgments against your company?

Respectable companies should also list the maximum generating capacity for their systems and readily provide estimates of how much energy the system will produce monthly or annually. With this figure, it is easy to compare against your current utility bills and see whether the home solar installation will cover your energy use.
