Mistakes Homeowners Make When Choosing Solar Panels

Avoiding these common mistakes can help you make a more informed decision when selecting a solar panel system for your home.

With the rising appeal of solar energy, more homeowners are considering installing solar panels to cut down on electricity costs and reduce their carbon footprint. However, choosing the right solar panels is not as simple as picking the first option that catches your eye. Many homeowners make mistakes during the process that can lead to suboptimal performance, unexpected costs, or underwhelming savings. Understanding these common pitfalls can help you avoid costly errors and make the most out of your solar investment. Here’s a look at the top mistakes to watch out for when selecting solar panels for your home.

Focusing Solely on Cost

One of the biggest mistakes homeowners make is choosing a solar panel system based solely on cost. While it’s tempting to go for the cheapest option, this can backfire in the long run.

Lower-priced panels may have lower efficiency rates, shorter lifespans, or limited warranties, resulting in lower overall savings over time. Instead of just looking at the upfront price, consider the quality, efficiency, and warranty of the panels. A slightly higher investment in a reliable system often yields better long-term returns and fewer headaches.

Overlooking Panel Efficiency and Output

Efficiency is a critical factor in determining how much electricity your solar panels will produce. However, many homeowners overlook this metric, assuming that all panels perform the same.

Panel efficiency refers to how well the solar cells convert sunlight into electricity. Higher efficiency means that the system will generate more power from a given amount of sunlight. If your roof has limited space, you’ll want panels with higher efficiency ratings to maximize your output. Always compare efficiency ratings and choose panels that best meet your home’s energy needs and space constraints.

Ignoring Roof Condition and Orientation

Solar panels are typically mounted on roofs, so the condition and orientation of your roof are crucial considerations.

Installing solar panels on a roof that needs repairs or replacement is a common mistake that can lead to costly reinstallation fees down the road. Before going solar, have a professional assess your roof’s condition. Additionally, the orientation and tilt of your roof impact how much sunlight your panels receive. A south-facing roof with a 30-degree tilt is ideal for solar production in the Northern Hemisphere. If your roof isn’t ideally oriented, you might need more panels or a specialized design to compensate.

Underestimating Your Energy Needs

Many homeowners miscalculate their energy needs when selecting a solar panel system.

This can result in either an oversized system that’s unnecessarily expensive or an undersized system that doesn’t meet your power requirements. Analyze your electricity bills over the past year to identify your average consumption and peak usage times. Factor in any future changes, such as adding an electric vehicle or expanding your home, that might increase your energy needs. This way, you can size your system appropriately to maximize your savings.

Disregarding Incentives and Financing Options

Solar incentives and financing options can significantly reduce the cost of going solar, but many homeowners either overlook these benefits or fail to take full advantage of them.

The federal solar tax credit, for example, can lower the total cost of your system by 30%. There may also be state and local incentives, rebates, and property tax exemptions that can help offset installation costs. Additionally, explore different financing options such as solar loans, leases, or power purchase agreements (PPAs) to find a solution that aligns with your budget.

Not Considering the Impact of Shading

Even partial shading can dramatically reduce the output of your solar panels.

Trees, chimneys, and nearby buildings can cast shadows that limit sunlight exposure, leading to lower energy production. If shading is an issue, you might need to invest in microinverters or power optimizers to minimize its impact. Conduct a thorough shading analysis to identify any potential obstructions and make necessary adjustments to your system’s layout to avoid losses in production.

Neglecting Battery Storage Options

With the increasing prevalence of time-of-use (TOU) rate plans and the phasing out of traditional net metering in some areas, having a battery storage system can be a smart addition to your solar setup.

However, many homeowners don’t consider batteries during the initial planning stages, only to realize later that they could benefit from storing excess solar energy for use during peak times or power outages. Including a battery in your system can enhance energy independence and increase overall savings, especially if your utility offers reduced compensation for exported solar power.

Choosing an Unreliable Installer

The quality of your solar installation can make or break your system’s performance and longevity.

Many homeowners make the mistake of choosing an installer based on the lowest quote, without evaluating their experience, certifications, or customer reviews. Poor installation can lead to wiring issues, roof damage, or underperforming systems. Take the time to research installers, check references, and verify credentials such as NABCEP (North American Board of Certified Energy Practitioners) certification. A reputable installer will help you design an efficient system and provide ongoing support.

Not Reviewing Warranties Carefully

Solar panel warranties vary widely, covering everything from panel performance to installation workmanship.

Homeowners often overlook the details of these warranties, only to face unexpected repair costs later. Look for a manufacturer’s warranty that covers panel performance for at least 25 years and an installer warranty for workmanship that lasts 10 or more years. Make sure you understand what is and isn’t covered and choose panels and an installer with strong, comprehensive warranties.

Underestimating the Importance of Maintenance

While solar panels are relatively low-maintenance, they still require periodic cleaning and inspections to ensure optimal performance.

Ignoring maintenance needs can lead to reduced efficiency and lower energy production. Accumulated dust, debris, or snow can block sunlight and reduce the panels’ output. Before choosing a system, ask your installer about maintenance requirements and whether they offer ongoing monitoring or cleaning services.

Avoiding these common mistakes can help you make a more informed decision when selecting a solar panel system for your home. By focusing on quality, efficiency, and proper planning, you’ll be better equipped to optimize your solar investment, enhance your energy savings, and contribute to a more sustainable future. Taking the time to evaluate your energy needs, research incentives, and choose a reliable installer will set you on the path to solar success.
