5 Reasons to Buy Rooftop Solar Panels in 2019

Don’t wait for another year.

Have you been putting off installing rooftop solar panels on your home? If so, 2019 is a good year to take action and actually do it. Why this year? Read on.

The American media seems to take pleasure in portraying us as a bunch of money-grubbing consumers who are only out for ourselves, but I am not buying it. We do not have to listen to them.

I believe that we can use our purchasing power to benefit the greater good and ourselves.

Sometimes it might be a small purchase like buying socks at a locally owned store instead online and having them shipped to you via an airplane. Or opting to buy organic spinach grown by a local farmer instead of spinach that comes in a sealed plastic bag from somewhere out of state.

A rooftop solar system is a big purchase that meets the above criteria.

In this post, we will talk about how purchasing rooftop solar panels for your home is a long-term investment that will pay for itself and more, add renewable energy capacity to your community, and support local jobs.

March 8, 2019, marked the beginning of the seventh year that our rooftop solar system has been silently generating clean renewable energy from the sun. Our system is tied to the electric grid so we share electricity back and forth with PG&E the investor-owned utility currently providing service to our county.

Let’s deal with the financial stuff first.

Save Money on Electricity

The net cost of our 22-panel 5.34 kW rooftop solar system was $14,767 including tax credits that we will discuss later. Solar prices have been decreasing so now our system would cost less.

Purchasing rooftop solar panels requires a significant investment upfront. Beware of sticker shock that may cause you to waver and lose sight of the long-term benefits.

I propose a little exercise to help you think about a large amount of money in a different way and this one never pays for itself or provides free electricity.

Many people, perhaps including you, have a habit of buying a cafe latte, specialty juice drink, or another treat each day during the workweek.

Let’s say you do that 48 out of 52 weeks a year. To make it simple we will use $5.00 as the cost of the treat. Below is an example of how much money you will spend over a ten-year period on just that one item.

Rows of Green Dollar Signs

5 items a week x 48 weeks a year = 240
items per year x 10 years = 2,400 items x $5.00 each = $12,000.

You may think this is a silly example, but it does demonstrate how you, I, and everyone else can easily spend a large amount of money without really thinking about it.

Payback Period

Your tangible electricity savings will begin at the end of your payback period, which is however long it takes your electricity savings to equal the total net cost of your rooftop solar system.

Last May, I decided to attempt to calculate the payback period for our solar panel system.

I had the data. However, I soon discovered the complexity of the task. It would mean calculating electricity costs on an hourly basis 24/7/365 for 5 years. This was beyond the time I could allow to figuring it out.

Not willing to do nothing, I came up with a method to estimate our payback period, which turned out to be about 7 years. Even though it is likely that there are flaws in my approach, I think that I am well within the ballpark.

At this time next year, our rooftop solar system will have paid for itself and from then on electricity will be virtually free for the next two or three decades, except for PG&E fees. Solar panels decrease in efficiency over time, but after the 25-year warranty period ends, they will not suddenly stop working.

If you are interested in how I calculated our payback period, you can read about it in the post Rooftop Solar Panels are Worth It and this is Why.

Increase Your Home’s Value

In recent years, especially here in California, several things have occurred making it even more financially attractive to purchase rooftop solar panels for your home.

  1. In January 2017, the California Regional Multiple Listing Service recognized that a rooftop solar system is a positive selling point for many home buyers so they added standardized fields that enable realtors to enter energy production for their listings.
  2. The California legislature upped the ante on renewable energy in 2018 by enacting a law requiring solar panels on all new homes.
  3. I do not have a crystal ball, but I doubt you will disagree with me when I suggest that electricity prices will only continue to increase. Where I live the average price of a kWh of electricity has steadily increased by 22.4% in the past 6 years, which is substantially higher than the national inflation rate.

When you decide to sell your home, savvy prospective home buyers are likely to appreciate that they can instantly save on their electricity bills without doing a thing.

Receive a Solar Investment Tax Credit

Mostly free electricity in the future and adding to your home’s value are two sound financial reasons to purchase a rooftop solar system. A compelling reason to do it in 2019 it that this is last year can receive the full 30% federal tax credit.

Solar-Electric Property
  • 30% for systems placed in service by 12/31/2019
  • 26% for systems placed in service after 12/31/2019 and before 01/01/2021
  • 22% for systems placed in service after 12/31/2020 and before 01/01/2022
  • There is no maximum credit for systems placed in service after 2008.
  • Systems must be placed in service on or after January 1, 2006, and on or before December 31, 2021.
  • The home served by the system does not have to be the taxpayer’s principal residence.
The 30% tax credit we received for our initial rooftop solar installation resulted in a refund from the federal government. This photo shows 3 of the 6 additional solar panels we bought with the money.

I hope you can see that owning a rooftop solar system makes financial sense. Now, let’s look at how going solar contributes to the greater good.

Build Renewable Energy Capacity in Your Community

Extracting, transporting, refining, storing, and burning fossil fuels (coal, oil, and natural gas) is a dirty and dangerous business that is jeopardizing the health and well-being of people everywhere, especially the people who live near fossil fuel extraction sites, rail lines, refineries, pipelines, and power plants.

Each one of us can choose to help our country get off fossil fuels by taking a variety of actions from running our dishwashers after peak electricity demand time to installing solar panels on our roofs.

Using the existing real estate available on top of our homes and other buildings to generate clean renewable energy just makes sense to me. The roof is already there so why not use it. If I were an investor-owned utility executive, I would be renting every rooftop I could get my hands on and installing solar panels.

Keep Your Money in Your Community

I am a fan of locally owned businesses, including solar companies, for a number of reasons. First and most importantly, I know that my money is supporting jobs in my own community versus lining the pockets of far distant shareholders who have never heard of my town or me.

Local companies are embedded in the communities they serve providing jobs, spending money, and contributing to causes important to their employees and the community.

We selected A.M. Sun Solar for our home rooftop solar project. I think they embody what is wonderful about locally owned companies. Here are a few examples.

The people at A.M. Sun Solar treat me like a person, not a number.

Years after our installation, Glen, Cory, and now Brian, are always willing to answer questions or provide information for a post I am writing.

The company gives back to the community by donating time and money to local organizations like Jack’s Helping Hand and the Paso Robles Children’s Museum.

Of course, just like any other company that you give your business to a locally owned company needs to provide quality products and services at a reasonable price. I chronicled this aspect of our relationship with A.M. Sun Solar in the posts Go Solar with Home Rooftop Photovoltaics – We Did and Rooftop Solar Costs Less than You Think.

Be Part of the Solution

Okay, so now I have shown you the money and presented you with an opportunity to help build the renewable energy capacity of your community while supporting local jobs. What could be better?

If you call a local solar company tomorrow, you could have solar panels on your roof before the arrival of the hot summer weather. This time next year you could be claiming the 30% tax credit on your federal income tax return.

Better yet, you will be taking a significant step to live more lightly on Earth.

Wind Energy and the Environment

Wind is clean, renewable, and free.

Did you know that in 2017 wind energy accounted for more of the U.S. electricity supply than solar? I discovered this during Energy Awareness Month this October because I decided to learn about wind power.

After stumbling across Energy Awareness Month a few years ago, I resolved that each October I would tackle an energy project or learn more about an energy-related topic and share what I learned with readers. Some of the topics I have covered include Energy Action Month history, the Clean Air Act, energy savings tips, rooftop solar tax incentives, and a review of the book Reinventing Fire.

This year wind energy is on my mind because the federal government and at least two wind companies are eying the ocean waters off San Luis Obispo County where I live on the California Central Coast.

Just last week, the U.S. Department of the Interior announced it is ramping up efforts to bring more offshore wind farms to federal waters off the United States’ coastlines. The Bureau of Ocean Energy Management (BOEM), the federal agency that manages the development of U.S. outer continental shelf energy and mineral resources, published some of their plans in the Federal Register.

Reading these announcements and news articles made me realize that I did not know much about wind energy so I set out to educate myself and share what I learned. You may not think that wind energy is pertinent to your community, but it is when you expand your vision to a society powered by clean renewable energy like the wind.

The intent of this post is to provide you with an overview of wind energy including its environmental advantages and disadvantages and to offer you some ideas for actions you can take to support wind energy if you choose to do so.

Wind Energy Basics

Even if you have never seen a modern wind turbine in action, you have probably seen wind filling the sail of a sailboat or turning the blades of a windmill.

All three are harnessing the motion (kinetic energy) of the wind. The wind turbine uses the wind to produce electricity, the sailboat uses it to propel the boat forward and the windmill uses it to pump water.

If you only have 60 seconds, I think the video below gives a good overview of how an offshore wind turbine works. There are more video links in the resources section at the end of the post.

Like solar, wind can supply electricity for homes, businesses, farms, communities, and power plants.

Solar panels on a home rooftop or wind turbines on a family farm are referred to as distributed energy meaning the electricity is consumed close to where it is produced. If distributed sources send their electricity to the electric grid, an entire community can share the power.

Large groups of wind turbines constitute a wind farm and can supply electricity for an industrial complex or to a utility-scale power plant, which then distributes it to their customers via the electric grid.

Most of the wind turbines producing electricity in the U.S. are land-based. A few have been around since the 1980s like the San Gorgonio Pass Wind Farm you see as you drive down Interstate 10 on the way to Palm Springs, CA.

An offshore wind farm is one that has wind turbines in the ocean or a large lake. The first U.S. offshore wind farm did not come online until just two years ago. Rhode Island made history when the Block Island Wind Farm off the coast of Block Island began sending electricity to the grid in December 2016.

Wind Industry 2017 Highlights

In 2017, wind accounted for 6% of utility-scale electricity produced by renewable energy sources, hydropower was 7%, biomass 2%, solar 1%, and geothermal less than 1%. 1

Wind blowing across the U.S. in 2017 provided more than 10% of the total electricity generation for 14 states, and more than 30% in Iowa, Kansas, Oklahoma, and South Dakota. Texas had the highest wind electricity generation capacity of any state. 2

Unlike coal, natural gas, or petroleum, the wind is a domestic energy source that cannot be exported. The wind industry provides jobs, lease payments for landowners, and property, local, and state tax revenue.

The U.S. wind industry employed 105,500 people in 2017. 2

Most of the components of wind turbines installed in the United States are made in the U.S. by 500 wind-related manufacturing facilities across 41 states. In 2017, U.S. based General Electric was ranked second in U.S. market share for wind turbine manufacturers. 2, 3

During 2017, over $11 billion was invested in new U.S. wind projects. 2

Next, we will explore some of the environmental advantages and disadvantages associated with producing electricity from wind.

Environmental Advantages of Wind Energy

Burning fossil fuels like coal and natural gas to generate electricity emits a whopping 34% of U.S. carbon dioxide emissions that contribute to global warming. 4 We could bring that figure to zero by transitioning to clean renewable energy, like the wind.

Wind energy is clean (does not produce emissions) and renewable (replenishes itself).

Wind blowing across Earth’s land and waters is free for everyone. Of course, capturing wind and converting it into electricity is not free but once a wind turbine or wind farm is installed, it operates on free energy for 20 to 25 years.

Wind turbines do not spew greenhouse gases and pollution into the air, which is good for your health and the environment.

Another major benefit of wind energy is that wind turbines do not deplete or pollute groundwater basins, rivers, or lakes that tens of millions of people rely on for drinking water and they do not pollute the ocean.

Land use for wind turbines and wind farms has pros and cons.

On the plus side, a wind turbine only occupies a small piece of land so other activities like agriculture, ranching, and recreation can go around them.

On the downside, the best place for wind turbines is in wide-open spaces and on ridge tops, which can be in remote places that do not have roads or transmission lines. Building infrastructure disrupts ecosystems and causes pollution and erosion. In the ocean, installing platforms (on the seabed or floating) and undersea cables can cause similar environmental issues.

Environmental Disadvantages of Wind Energy

A drawback of wind energy is that it fluctuates so it may not produce a continuous supply of electricity all the time.

Americans expect electricity to be instantly available 24/7/365 so wind power needs to be backed up with storage or an additional electricity supply source. Battery storage systems add to the environmental footprint of wind systems. If backup electricity is provided by a power plant that burns fossil fuels, it reduces the environmental benefit of wind.

Mining for rare earth metals and making steel and concrete to build wind turbines and platforms has a negative environmental impact including greenhouse gas emissions, pollution, and high energy use. The thing is that this can be said about anything that uses these materials so it is not unique to wind energy.

Wind turbines can present a hazard to birds, bats, and marine animals.  Careful placement of wind turbines can alleviate this issue.

Noise might be a problem if you live or work very close to a wind turbine or wind farm.  Noise may also affect nearby wildlife both on land and in the ocean.

Some people have an aesthetic concern about seeing a wind turbine or wind farm in their viewshed, a term I first saw while reading an article about our potential local offshore wind farms.

Yes, wind does have some drawbacks, but they are insignificant when you consider the widespread danger and damage associated with every aspect of the fossil fuel industry.

Wind energy capacity has skyrocketed since 2001 and continues to grow.

What Can You Do to Support Wind Energy?

You may not have a wind farm project going on where you live, but you can still support wind energy. Here are a few ideas to get your creative juices flowing.

  • Install a residential-scale wind turbine in your yard.
  • Learn more about wind energy and talk about it with your family, neighbors, and coworkers.
  • If you do have a wind project pending in or near your community, get involved by attending town hall meetings and other events that give you an opportunity to learn about the project and to voice your concerns and/or support.
  • Tell your local and state elected representatives that you are in favor of wind energy and ask them what they are doing to support it.
  • Request that your U.S. senator and congressperson author and/or support a bill extending renewable energy tax incentives.

What am I doing? I am going to find out what I can about the two potential projects off our coastline and get involved in some way.
