How much will a solar panel cost? Are solar panels worth it to install on your rooftop!

Solar Panel Cost and Variables

When people are trying to determine the cost of solar panels, they need to take many different factors into account. For one thing, the cost of solar panels will vary tremendously based on the energy requirements of a given household or business. There are also tax credits and rebates and state incentives to consider, since all of these potential discounts can affect the ultimate cost of a solar panel system. People will ask: are solar panels worth it? For many people, the answer will be ‘yes.’

Decreased Solar Panel Cost

The cost of solar panels has gone down with time. Very recently, people would pay between seven and nine dollars per watt. Solar panel systems are typically measured in terms of kilowatts, meaning thousands of watts, so they could be expensive to install.

In 2017, solar panels have cost people in the United States between 2.87 and 3.85 dollars a watt, meaning the cost of solar energy per watt has decreased by more than half in a short number of years. The average solar system size in the United States is 5 kW, so even before tax credits, many Americans will spend 16,800 dollars for a solar panel installation.

This is half what Americans used to spend on solar energy only a few years ago. With tax credits, Americans can save an additional six thousand dollars or three thousand dollars, so they might spend ten thousand dollars on their solar panels.

However, some households will need much larger systems than this. They might spend twenty thousand dollars on their solar panels. There are business buildings that might actually have lower energy needs than some households. Other business buildings will have much higher solar energy needs.

A medium-sized business will often need a solar system that can generate 14 kW. This is almost three times the size of the system a household will need. A micro business might spend even less than homeowners on solar energy. A very large business might need twice as much energy as a medium business.

Some businesses will spend as much as forty thousand dollars on their solar panels even with the tax credits and other discounts. However, this might not be the case for some smaller businesses and businesses that are found in sunny locations.

Calculating Solar Energy Needs: Are solar panels worth it?

EnergySage and many other services have calculators that people can use in order to estimate the amount of solar energy they are ultimately going to need. These calculators will simplify the process for business owners and homeowners substantially.

In order to accurately calculate the cost of the solar panels that they will need, people need to know how many hours of sunlight they will get per day on average in their areas, their typical energy usage, and the amount of electricity that the solar panels in question can generate.

The fact that solar panels generate DC and people need AC also means that around twenty percent of the power is lost, since this process is not completely efficient. Using solar energy calculators allows people to take into account all of those factors at once.

It is possible to do these calculations manually. However, this means that people will need to know all of the figures involved, and they will need to know how much sunlight their home gets on average. Most solar energy calculators will ask people to enter in their addresses, and the system will be able to estimate the amount of sunlight that people will typically get based on their location. This is a step that is difficult for people to perform on their own otherwise.

Suniva Solar Panels

Suniva solar panels are very effective in general. They have long product warranties attached. Many of them will use high-quality and advanced technology, including an anodized aluminum frame. The costs associated with Suniva solar panels will always vary. It’s difficult to generalize about the price. However, the fact that these solar panels have a great performance and can generate more than 250 watts of peak power means that they should cost less than many others in practice.

SolarWorld solar panels 

SolarWorld is known for having a lot of solar panels that give a great performance. Their design is more stylish than what people will find with a lot of other solar panels. It’s also easier to install them than it is to install a lot of other solar panels on the market. People will need quotes in order to really determine the associated costs with SolarWorld panels. However, this is another service that will tend to offer cells that have a high performance. As such, the costs will often be lower as well.

LG solar panels

The energy output and efficient standards for LG solar panels are very high, and most people should have high hopes for them in general. The power that people can get with LG solar panels should be long-lasting. The warranties for LG solar panels are also extensive. This company has a wide range of different products, making it easier for a lot of people to find what they need. LG also has its own convenient calculators on hand that will help people understand exactly how much they can expect to pay if they decide to use LG solar panels.


People who have very low energy needs will almost certainly find that solar panels are worth it. As always, it is important to remember that once people install solar panels, they will continue generating energy that will eventually pay for itself. People who pay for the entire cost of the solar panels will get energy that has no additional costs from that point onward. Some people who use a lot of energy will pay off their solar panels in only seven years. In the case of businesses that use a lot of energy, this can potentially happen very quickly.

Is solar worth it?

Benefits of going solar versus costs 

This blog attempts to  provide an analysis of some things you might want to know in order to answer the question: Is solar worth it? In many cases, to be able to answer this question, it may require that you determine the benefits of going solar versus costs.

With regards to solar energy, there are various benefits which come at a cost. Hence, we can simply answer this question by knowing the solar benefits versus its costs. With the emergence of online solar tools, you probably don’t need an intensive research to determine the costs or knowing whether solar is right for you or not. 

Emergence of online solar tools 

Online solar tools like the EnergySage have simplified this process and can help you determine your specific solar potential by just inputing very limited data such as your average monthly electricity bill and your address. Once you provide such details, they have an inbuilt solar panel cost calculator in their platform that does the calculations for you in terms of solar costs, financing and projected savings for up to 20 years. 

Is solar worth it? Costs versus benefits

1.     Solar energy will help you to reduce your energy bill. However, this might not be the case for you because it is based on your current electricity tariffs and how many solar panels you need to install.

Hence, if you are able to offset a lot of your current electricity from the grid at a cheaper solar tariff using solar power, then perhaps you can achieve a significant amount of savings.

Using online solar tools and inputting your current address and current electricity bill, will help you quantify these savings and provide you with a specific estimate about the percentage of your bill that can be reduced with going solar. You can sign up and try it here.

2.     Another benefit is reducing your carbon footprint, which depends on the size of the solar PV system that you install. Solar panels reduce greenhouse gas emissions because they do not emit or burn any type of fuel, but run on solar energy that is free fuel and doesn’t emit any carbon emissions.

For environmentally conscious people, this is a plus and makes them feel good that you are actually using a clean source of energy that will help to mitigate climate change and help to protect or sustain the environment for current and future generations.

3.     Depending on what financing model you use to purchase your solar panels; going solar will help to save you a good amount of money in the long-term.

However, savings are site specific depending on your geographical location and the policy and regulatory framework of your country or state. In most cases, if you have a rooftop that receives a good amount of sunshine; you will have some type of savings in the long-term.

This depends on the payback period or the number of years your solar panels pay for themselves; but once this happens everything else depends on your current electricity tariffs and how much money you are saving.

If you took a loan or paid cash for your solar panels; this will affect how much money you can recoup from your solar investment.

Some case studies that we have checked show people saving anywhere from $20,000 to $30,000 in a period of 20 years. To get your specific estimates, please refer to this online solar tool to see how much you can save in 20 or 25 years if you go solar.

Is solar worth it? Going solar has its downside. What is it?

1.     There is no sunshine at night and because of this, it means your solar panels will not be able to generate any electricity and that calls for you to think about what to do.

In that case, some states or countries encourages a concept called “net-metering” which allows you to have a bi-directional meter and your PV system is connected to the utility grid.

With this arrangement, you can feed any excess solar power that is usually generated during the day (when there is a significant amount of sunshine) and consume it at night when your PV system is not generating any solar power.

At the end of the day, your savings result when you subtract how much you feed into the grid from the amount of kilowatt-hours consumed from the grid.

As such, the utility company sends you in most cases a credit if you have a surplus. However, in some places the net-metering concept may not exist and that calls for you to buy battery banks to store excess solar electricity generated during the day and use it at night.

2.     Depending on your location, solar power may not meet all your electricity needs meaning you may need to supplement it with grid power. However, these depends on the amount of sunshine your site location/rooftop is able to receive and how many solar panels you need.

That means, if you have a high-energy requirement to meet, you also require many solar panels to meet demand. For instance, if your house has an energy requirement of 10 kW you will need a 10 kW PV system to meet this demand.

Before deciding to go solar, your solar provider will also provide you with grid interconnection requirements, including, but not limited to licensing and regulations concerning grid interconnection while Fire departments will have building accessibility requirements, particularly for roof-mounted systems.

Some jurisdictions formally specify these standards and will confirm that the system meets the requirements during the permitting phase and final approval process. In the states that do not have such requirements, it is important for the government agency and the system owner to gain fire department approval early in the process
