SolarJerry Lee

Are you a homeowner interested in saving on energy costs by installing solar panels? Solar panels have become increasingly popular over the years and with good reason - they provide an environmentally friendly and cost effective way to produce electricity. Whether you're looking into purchasing your own residential solar system or just researching their financial benefits, this blog post will give you everything you need to know about how much money do solar panels save, along with factors that can affect the cost of installation and calculations used for determining potential savings. Let's take a deeper dive into the economics of solar savings!


Average Cost of Solar Panels


The average cost of solar panels with installation can vary depending on several factors, including the size of the system, the type and efficiency of the panels, the region where you live, and any applicable incentives or tax credits. As of the first quarter of 2023, the residential solar cost was approximately $3.28 per watt, according to a report from Wood Mackenzie.

On average, a 6-kW solar panel system with installation ranges from $13,000 to $20,000. However, it's essential to note that individual solar installations can differ significantly in price based on various considerations. Some smaller systems might cost as low as $5,000, while larger, high-end installations can cost up to $40,000 or more.

To get a more accurate estimate of the solar panel cost for home, it's essential to get multiple quotes from reputable solar installers in your area. Additionally, check for available incentives, tax credits, and rebates offered by the federal government, states, and local utilities, as they can significantly reduce the overall cost of installing solar panels.

Factors That Influence Solar Panels Savings

Several factors play a significant role in determining the potential savings from solar panels:

  • Local Electricity Prices: The cost of electricity from the utility company varies widely based on your region. Higher electricity prices can result in greater savings from solar panels since you can offset more expensive grid power with solar-generated electricity.
  • Solar Panel System Size: The size of the solar panel system you install directly impacts the amount of electricity it can generate. Larger systems can cover a higher percentage of your electricity needs, potentially reducing your reliance on the grid and leading to more significant savings.
  • Solar Panel Efficiency: The efficiency of the solar panels determines how much sunlight they can convert into electricity. More efficient panels can generate more power in the same amount of space, leading to higher potential savings.
  • Sun Exposure and Climate: The number of sunlight hours your location receives and the local climate play a crucial role in solar panel performance. Areas with ample sunlight can generate more electricity and achieve greater savings.
  • Energy Consumption: The amount of electricity your household consumes influences the savings from solar panels. High energy users can benefit more from solar installations as they have a greater opportunity to offset expensive grid power.
  • Net Metering Policies: Net metering allows homeowners to sell excess solar energy back to the grid, reducing their electricity bills further. The specific net metering policies of your utility company can affect the amount you save with solar panels.
  • Upfront Installation Costs: The initial investment in installing solar panels can vary based on the size and complexity of the system, as well as the local installation costs in your area. Lower installation costs can lead to faster payback periods and increased savings over time.
  • Incentives and Tax Credits: Various federal, state, and local incentives and tax credits can significantly reduce the upfront cost of installing solar panels. Taking advantage of these incentives can enhance the overall savings from solar.
  • Solar Battery Storage: Adding a solar battery system allows you to store excess energy generated during the day for use during periods without sunlight. Solar batteries can increase savings by further reducing dependence on the grid.
  • Panel Degradation and Lifespan: Over time, solar panels experience degradation, meaning they may produce slightly less electricity than when first installed. Considering the panels' expected lifespan is essential when estimating long-term savings.

By carefully considering these factors and conducting thorough research, homeowners can better understand the potential savings from solar panels.

Calculate How Much Solar Panels Save


Calculating how much money do you save with solar panels involves several steps and considerations. Here's a detailed and clear guide to help you estimate your potential solar savings:

1. Gather Information:

  • Obtain quotes from multiple solar installers to determine the upfront installation costs, which will include the cost of the solar panels and the installation fees.
  • Research and identify any federal, state, or local incentives and tax credits available for solar installations. These will reduce the upfront costs and should be factored into the calculations.
  • Collect your electricity bills for at least six months to understand your average monthly electricity consumption and costs.

2. Calculate Net System Cost:

Subtract the total incentives and tax credits from the upfront installation costs to get the net system cost. This is the amount you will need to invest out-of-pocket.

3. Estimate Monthly Electric Bill Savings:

Based on the size of the solar panel system and its expected energy production (usually measured in kilowatt-hours or kWh), estimate how much of your monthly electricity bill can be offset by solar energy. It should be noted that how much money do solar panels save per month depends on factors such as panel efficiency, sun exposure, and energy consumption patterns.

4. Calculate Payback Period:

  • Divide the net system cost by your estimated annual electricity bill savings. The result will give you the payback period, which is the time it takes to recoup your initial investment through savings on electricity bills.
  • Payback period (in years) = Net system cost / Annual electricity bill savings

5. Calculate Long-Term Savings:

  • After the payback period, consider the savings as pure savings. Solar panels are typically warranted for 25 years, but their actual lifespan can be longer. Calculate the total savings over the entire lifespan of the panels.
  • Long-term savings = (Lifespan of panels - Payback period) * Annual electricity bill savings

These are the basic steps on calculating how much money do solar panels save on electricity bills, there are still some additional factors that need to be taken into account:

Panel Degradation:

  • Over time, solar panels may degrade, producing slightly less energy each year. Check the panel manufacturer's warranty for information on degradation rates. Typically, panels have a performance guarantee of around 80-90% after 25 years.
  • Adjust the estimated energy production each year to account for degradation and update the long-term savings calculation.

Future Electricity Prices:

Take into account historical trends in electricity price increases. If electricity prices continue to rise, your solar savings may become even more significant over time.

Other Solar Savings:

If you plan to add solar batteries, solar portable power station to your system, estimate the potential additional savings from storing excess energy and using them during peak hours or when the sun is not shining.

By following these steps and considering all the relevant factors, you can make an estimation of how much solar panels can save you over their lifespan. Remember that actual savings can vary based on individual circumstances, so it's essential to tailor the calculations to your specific situation. If you need assistance with the calculations or have specific questions, consult with reputable solar installers or energy experts who can provide personalized advice based on your location and energy needs.
