How much does a solar roof cost? Though many know solar power requires an expensive investment, it can be challenging to pin down an accurate estimate because so many variables are involved. The size of your home, climate, and manufacturer all contribute to variability in total cost, so it’s important to do your homework before you commit.

That being said, although the initial cost of installing solar panels is certainly high, it will save you money long term. Since you can power your entire home with solar roof panels alone and no connection to the grid, you could cut your electric bill in half. For a more specific savings estimate, check out Google’s Project Sunroof. With this tool, you can simply plug in your address will estimate what kind of savings you might realize by switching to solar power.

What’s more, installing solar panels will reduce your home’s reliance on the grid. Though some regions power their grid with natural gas, solar, or wind energy, more than half of the U.S.’s energy is from fossil fuels. By going solar, you can play your part in reducing your region’s reliance on coal power and do your part for the environment.

If you’re on the fence about purchasing solar panels for your home, keep reading for some pros and cons to help you decide.

Solar energy pros and cons

Solar roof costs aren’t the only consideration when you’re making your decision. The pros and cons of switching from your local power grid to solar power certainly tip in favor of the pros.

Pros of switching to solar power

  • Reduces electric bill
  • Provides a significant return on your overall investment (ROI)
  • Gives a sense of energy independence
  • Environmentally friendly

Cons of switching to solar power

  • Solar panels don’t work as well when there’s limited direct sunlight
  • High initial cost
  • Clunky solar panels are not always aesthetically pleasing

What are the costs of installing solar panels?

The average cost to install solar panels is $15,000 to $25,000, depending on the size of your roof. To break it down further, according to, “The cost of solar panels as of July 2021 is about $19,300 after tax credits ($2.76/Watt for a 10 kW system).”

Likely, you’ll save more than this over the long run. While the exact figure depends on how much energy you generally consume and the average cost of electricity in your area, switching to solar power generally leaves you with a bill that’s 20% the price of your previous ones. That number rises to 40% for homes with electric heating or air conditioning systems!

Better yet, state governments also offer tax incentives for those who install renewable energy systems like solar panels (and even more so for electric car owners).

What are the costs of installing a Tesla solar roof?

Tesla’s solar roof consists of a 70-micron thick, fully tempered glass top layer and another 150-micron thick textured protective layer to shield against minor impacts. The high-performance, low-cost roof tiles are four inches wide and have integrated photovoltaic cells embedded into them. Due to their design, these cells can generate up to 80% more electricity than traditional panels.

As for the overall price, you’re looking at spending upwards of $39,017, according to Tesla estimates. This price includes what you can expect to save from local and national tax incentives. Obviously, the average cost is far higher on the front end than standard solar panels, and you must also purchase a Tesla Powerwall. However, it is an energy-efficient solution that’s a great alternative to bulky rooftop panels.

You’ll also end up saving more with the Tesla solar roof over time since these solar roof shingles cost $2.01 per watt, which is less expensive than the average solar panel cost nationwide.

When do solar panels begin to pay off?

Typically, homeowners say their solar roofs pay for themselves after 9 to 12 years. At this point, the panels have been able to save money on electricity to reduce energy bills in the home. After nine to twelve years, depending on where you live, your solar roof will have paid for itself, meaning you’ll break even with the startup costs.

Thankfully, solar roofs last up to thirty years with regular maintenance and the right conditions. If you live in an area where tornadoes, hail storms, and hurricanes are infrequent, solar roofs can last a long time without needing replacement. This means you’ll notice an even greater ROI.

Is solar power right for you?

Though you’ll see great savings in the long run, it’s still a pretty hefty investment upfront. Before you make a decision, take the time to calculate the costs of your current electricity usage. Compare that to any savings you might gain by switching to solar power, taking into account your location and any government incentives for which you may be eligible, too!

If you’re a homeowner, then you’re likely aware that traditional electric power costs are rising. The grid is based on outdated technology that’s more than a hundred years old, and the infrastructure definitely needs an eco-friendly update. With the environmental and monetary costs of fossil power, making a move toward solar power just makes sense.

Costco rotisserie chicken

Chicken is a fan-favorite food, and for good reason — from barbecue chicken to chicken quesadillas to chicken parmigiana, it’s a lean protein that serves as the centerpiece for so many different meals. Consider this: In the early 1970s, per capita poultry consumption in the U.S. was almost 50 pounds; these days, it’s more than 100 pounds per person.

Of course, chicken hasn’t evaded the raging inflation that’s hiking up expenses every time we go to the grocery store (or gas station, shopping mall, or — well, just about anywhere.) According to the USDA, wholesale poultry prices are predicted to increase between 19-22% this year.

The one thing we love about Costco is that we can buy the things we love in bulk. The one thing we wish Costco would change? It forces us to buy things in bulk. We know, it’s the ultimate catch-22 of first-world problems.

Croissants from Costco are some of the best you can buy, which itself is a weird statement. How is it that a warehouse store has baked goods that are better — and often fresher — than a lot of local bakeries? We love Costco croissants, but most households can’t get through 12 big croissants in a few days’ time. What can you do?

If you love Costco as much as we do, you probably think there is no bad time to hit up the superstore. But if you're looking to avoid the rush of people and long lines, there are better times to go than others. As many know, Reddit has a wealth of information about Costco under the subreddit r/Costco, where droves of shoppers log in to ask all sorts of questions — from the best deals to their favorite purchases. One recently asked the question: "What is factually the best time to go to Costco? Weekdays, weekends, sunny, rainy, snowy days?" and the answers do not disappoint.

The best of the best
Of course, it wouldn't be social media without some entertainment thrown in, and this question got plenty of those responses. The most popular: "When you are craving a hot dog." While it's funny, Costco makes headlines for never increasing the price of their hot dog plus soda deal in the 40 years it's served up the tasty treat (which can be yours for the low price of $1.50). Another happy shopper recently found another good time to go: "Apparently during [the] Super Bowl." Makes sense.
