Solar panels remain a popular choice for homeowners looking to harness the power of the sun. Unfortunately, not every house is an ideal choice for solar panel installation. Before choosing solar energy, it is essential to assess your home’s suitability. Discover key considerations to learn if your house is a good candidate for solar panels and make an informed decision that aligns with your environmental goals and financial objectives.
Understand the Importance of Determining Solar Panel Suitability
Investing in solar energy is a significant financial decision, and knowing whether your home can effectively harness the power of the sun is paramount to making a wise investment. By evaluating factors like sun exposure, your roof’s condition, and your energy consumption patterns, you can estimate your potential energy savings and return on investment (ROI).
Assess Your Solar Potential
Assessing your home’s solar potential is the first step in determining its solar panel suitability. Factors like solar exposure, shading, obstructions, and the average number of cloudy days in your local climate all influence whether your home receives enough sunlight to generate clean energy.
Solar Exposure and Orientation
Solar exposure goes hand-in-hand with your roof’s orientation: north, south, east, or west. Orientation affects the amount of sunlight your roof receives during different times of the day. South-facing roofs are ideal candidates for solar panels and capture the most sunlight in the northern hemisphere.
North-facing roofs receive the least direct sunlight throughout the day and year, making them less efficient for solar energy generation than other orientations. However, solar panel efficiency has improved over the years, and even north-facing installations can produce electricity.
To determine the average peak sun hours in your state, use Global Solar Atlas’ interactive tool to find the average global horizontal irradiation or peak sun hours. Additionally, you can enter your address into Google’s Project Sunroof interactive tool to check your home’s solar viability.
Roof Angle, Shading, and Obstructions
Like roof orientation, different types of roofs and their angles affect solar potential. Your roof’s angle should match your location’s latitude to maximize your solar exposure. Your installer will make necessary adjustments to align your panels to the optimal angle for energy production. Most experts agree that the optimal angle for roofs in the northern hemisphere is between 30 degrees to 45 degrees.
Shading from nearby buildings and trees can diminish your solar output. It is essential to assess potential shading throughout the day and identify obstructions. This evaluation helps you identify obstacles like chimneys and vents that affect panel placement.
Roofs with too much shade or too many obstructions limit the size of a solar system and are not good candidates for solar installation.
Evaluate Your Energy Consumption
Before deciding on solar energy, assess the amount of energy your home consumes and the cost by reviewing past energy bills and electricity rates. This evaluation can help you determine your average monthly usage and identify seasonal variations to estimate how much solar energy your installation needs to generate to meet your demands.
On average, solar companies recommend solar panel installation to homeowners paying $75 or more for their monthly electricity bill to make the most of solar savings.
Calculate Future Energy Needs
Your lifestyle and household evolve, and your energy needs change. Consider potential changes in family size, appliances, or the addition of electric vehicles that might affect your electricity consumption. By factoring in future energy variables, you can more accurately estimate the size and capacity of your solar panel system and your overall financial investment.
Conduct a Structural Analysis
The condition of your roof is an important factor in determining whether it can support solar panels. If your roofing material is in poor condition or nearing the end of its lifespan, have your roof repaired or replaced before installing solar panels.
Different roofing materials such as wood shakes, slate tiles, asphalt shingles, or concrete tiles have varying load-bearing capacities, making it crucial to understand your roof’s characteristics. Inspect your home for signs of damage, leaks, or deterioration before moving forward with your solar panel installation.
Depending on the size and material of your roof, you can expect to spend an average of $14,643 for a roof replacement. If your roof is in good condition and requires no structural supports or upgrades, it is a good candidate for solar panels depending on the other requirements you meet.
Review Local Regulations and Incentives
Review local solar policies and regulations that govern the installation process in your area and incentives that increase the cost-effectiveness of solar power.
Local Regulations
Local solar policies govern solar panel installation. These regulations impact design, installation, and cost. Consider:
- Permitting requirements: While your solar installer will probably handle obtaining permits, it is important to understand the process for installing your solar system to ensure you remain compliant.
- Zoning or HOA restrictions: Some communities limit placement, size, and visibility, making solar panel installation unfeasible. Most HOAs prohibit ground-mounted systems.
- Interconnection policies: Your local utility companies set their own grid interconnection policies outlining the technical and contractual requirements for connecting your photovoltaic system to the national grid.
- Financial incentives: Review incentives, rebates, and solar financing offered by your local government, utility companies, or solar suppliers to increase your installation’s cost-effectiveness.
Solar Incentives
Solar energy systems are eligible for government tax credits. Systems installed between 2023 to 2032 are eligible for a 30% credit. There is no maximum amount a homeowner can claim and expenses include:
- Solar panels or cells
- Contractor labor costs, including permitting fees and inspection costs
- Balancing equipment, including wiring, mounting equipment, and inverters
- Energy storage devices with a capacity rating of 3 kilowatt-hours or greater
- Sales tax on expenses
Net Metering Policies
Net metering policies incentivize solar installation and increase the cost-effectiveness of your new system. If your system’s solar energy production exceeds your consumption, it feeds the excess energy back into the grid, a process known as net metering. Many locations allow you to earn credits through net metering, which lowers your utility bills.
Assess ROI
Consider the savings generated by offsetting your electricity bills, credits generated through net metering, and the value of all your incentives and rebates to calculate your return on investment. Compare all gains to the initial cost of your system to determine your payback period.
On average, solar panels reduce electricity bills by 50 percent to 70 percent, and most residential solar power systems have an average payback period ranging from five to 10 years. Well-maintained solar panels last between 25 to 30 years, leaving you 15 to 20 payment-free and reduced electricity bill years.
Consult a Solar Professional
Consult a professional solar installer to ensure an accurate assessment of your needs, system size, and potential savings. Consider the following factors:
- Obtain multiple quotes from reputable solar installers and companies to compare offerings, system design, efficiency, equipment, price, warranties, and installation services.
- Verify credentials to ensure your provider is licensed, insured, and certified in solar and roofing.
- Evaluate customer reviews from multiple sources like Trustpilot, Better Business Bureau, and Consumer Affairs to gain insight into the quality of work, customer service, and overall satisfaction levels.
FAQ About Solar Panels
Solar panel installation costs between $15,000 to $26,000 before incentives. They reduce your annual energy costs and increase your home’s value, making them a wise investment for many homeowners.
Solar panels are relatively low-maintenance. Experts recommend an annual inspection and cleaning to maximize efficiency.
Yes, solar panels will work on cloudy days. They only need a visible light spectrum. If it is light enough for you to see, your solar energy source can generate electricity. However, the stronger the sunlight, the more power your panels will generate.
