With the average cost of grid electricity increasing by 18% over the past two years, an increasing number of homeowners are opting for solar power to protect themselves from rising utility rates. How much can you save with solar panels? This article delves into the financial benefits of solar energy and the factors that influence your total savings.
How Much Can Solar Panels Reduce Your Energy Bills?
Over the 25-year lifespan of a solar power system, homeowners can save substantial amounts of money—often ranging from tens to hundreds of thousands of dollars—by significantly reducing their utility expenses. Installing solar panels on your roof allows you to substitute your traditional electricity bill with lower monthly payments for your solar setup.
As the cost of solar technology has decreased dramatically over the past four decades, these payments tend to be much lower than the expenses associated with conventional grid electricity.
If your current electricity costs exceed the monthly solar payments, you can enjoy noticeable savings by making the switch to solar energy.
Comparative Analysis of Solar and Grid Electricity Costs per kWh
A straightforward method to assess the cost difference between solar energy and grid electricity is to analyze the expense per kilowatt-hour (kWh), which is known as the levelized cost of electricity.
If you don't have solar panels, the levelized cost of electricity is simply the price your utility company charges. The map below displays the average utility rates in each state.
Is Solar Power a Real Cost-Saver?
The average cost of home solar electricity purchased on solar.com is approximately 8 cents per kWh, although this can vary depending on the project's size, complexity, and location.
As grid electricity prices continue to increase over time, usually at an average rate of 3% annually, recent years have seen even steeper, double-digit rate hikes within a single year.
By switching to solar, you can reduce your electricity costs, lock in stable rates for 25 years, and protect yourself from future utility rate increases.
Factors Influencing the Savings from Solar Panels
Your utility electricity rate and the cost per kWh of your solar energy system are the primary drivers in determining your potential savings with solar panels. However, there are several other aspects to consider when evaluating your overall savings.
Let’s take a closer look at various factors that influence how much money you can save with solar panels.
​
Maximizing Solar Energy Savings: Federal and Local Incentives
One strategy to maximize savings when transitioning to solar power is to take advantage of available local and federal incentives. Homeowners can significantly lower the overall cost of solar installation by leveraging the federal solar tax credit, which covers 30% of the entire project expense. For instance, if the total cost of a solar installation is $25,000, the federal tax credit would save the homeowner $7,500, reducing the net cost to $17,500.
Additionally, various local incentives offered by states, cities, and utility companies can provide further savings. For example, New York state offers a 25% tax credit on the installation cost, providing homeowners with even greater financial relief and making solar energy a more attractive and cost-effective option.
​
Financing method
Another key consideration is the way you choose to finance your solar system. Opting to pay cash upfront provides the highest savings, as it eliminates interest costs associated with loans. However, since not everyone has a substantial sum like $25,000 available, many homeowners opt for solar loans. These loans can deliver instant energy savings by swapping out your electricity bill for lower monthly loan payments. Nonetheless, over time, the interest on the loan will decrease the total amount saved from using solar panels.
​
Time
The return on investment for installing solar panels usually occurs within 7 to 10 years, providing more than 15 years to save money while the panels remain under warranty.
After the warranty period, solar panels don't suddenly stop working; instead, they continue generating electricity, though their efficiency gradually diminishes over time due to natural wear and tear.
Consequently, the longer you keep your solar panels—and the house they’re installed on—the more savings you can accrue.
​
Misalignment in the Solar System
Offset refers to the proportion of a household's energy consumption that is covered by the electricity produced from a solar system.
A system with a 100% offset generates an amount of electricity equal to the household's total energy usage, potentially eliminating the electricity bill entirely.
Achieving 100% offset or slightly higher is a common goal for homeowners because it can offer the maximum savings on energy costs.
That said, even solar systems that offset 50% or 75% of your energy usage can still lead to significant cost savings on your utility bills.
​
Sunlight and Its Effects
Another key factor impacting savings is the level of solar irradiance, or the amount of sunlight your solar panels receive. Increased solar exposure leads to greater energy generation, translating to higher savings. While location plays a significant role in determining sun exposure, shading from trees and other obstacles can also influence the efficiency of your solar panels.
Renewable Energy Incentive Programs
Net metering plays a crucial role in determining the savings potential of solar panels for homeowners. This system compensates solar panel owners for the surplus energy they contribute to the grid, which helps to lower utility bills even when solar generation is not occurring.
Typically, under net metering, each kilowatt-hour (kWh) of energy that a solar system feeds back into the grid balances out an equal amount of energy drawn from the grid.
However, utility companies are increasingly trying to reduce the benefits of net metering by offering lower rates for the energy exported from solar panels. For instance, California's NEM 3.0 policy slashes the rates for solar exports by over 75%.
Despite these changes, California residents can still achieve significant savings with solar panels under NEM 3.0, often totaling tens of thousands of dollars over time.
Discover Your Solar Savings: Calculate Your Potential Energy Cost Reductions
Opting for solar energy is a wise decision when faced with rising electricity costs. By switching to solar, you can replace your electricity bill with manageable monthly payments for your solar system. Over the 25-year lifespan of a solar panel system, you can save significant amounts, often in the tens or hundreds of thousands of dollars on energy costs.
Several factors influence your potential solar savings, with time being one of the most crucial. The earlier you adopt solar power, the sooner you reach the payback period and begin accumulating substantial savings.
An emerging software called SolarAPP+ aims to simplify the permitting process for residential solar installations, potentially shortening timelines and reducing associated soft costs.
Colorado has allocated $1 million to support the implementation of SolarAPP+ in local communities, and according to CALSSA, approximately 66% of California's population may soon benefit from this software.
As non-labor soft costs make up 44% of residential solar expenses, the adoption of SolarAPP+ could significantly decrease the overall cost of solar installations for homeowners.
Drawbacks of Solar Panels: Exploring the Downsides
One aspect our calculator doesn't address is the potential drawbacks of solar panels. Just like any energy source, solar energy comes with its own set of advantages and disadvantages. Rooftop solar systems are no exception to this balance.
​
Variability in Renewable Energy Sources
A significant drawback of solar panels is their reliance on sunlight to generate electricity, which means they cannot produce power during nighttime or on cloudy days. This intermittent production necessitates a system like net metering or battery storage for solar energy to be effective.
Net metering is a billing system that lets solar panel owners earn credits by feeding excess energy into the grid. These credits can then offset the cost of electricity they draw from the grid when their panels are not actively producing power.
While many states currently have net metering policies in place, there is a trend towards revising or eliminating these policies.
Utility companies in various states are pushing to modify or eliminate net metering, which could impact the benefits solar power users receive.
Following the recent approval of NEM 3.0 in California, other states may begin to consider similar changes, potentially leading to less advantageous billing practices for solar energy users in the near future.
Financial Constraints
A second drawback of solar panels is their high upfront costs, which can be a significant barrier for low- and moderate-income households. The installation of solar panels typically costs around $25,000 before taking into account any incentives or subsidies. Many homeowners may not have immediate access to this kind of capital or may not qualify for financing due to weak credit. As a result, these households miss out on the potential energy cost savings that come with solar power.
Additionally, there is a concern that residential solar can indirectly increase electricity costs for lower-income households that cannot afford to install solar panels. This phenomenon, known as the "cost shift" theory, suggests that utilities might compensate for the loss of revenue from wealthier households using solar panels by raising rates for those who remain dependent on the grid. This could potentially exacerbate the energy burden on lower-income households.
Deceptive Practices and Unreliable Installers
When considering the solar industry, it's important to be aware of scams and subpar installers, which can complicate the experience for customers. Many regrets related to solar panels arise from negative interactions with installers who deliver substandard work and provide poor customer service.
