4 Key Factors To Consider When Installing Solar Panels

By  //  February 28, 2024

Thinking about harnessing the sun’s power for your home? Installing solar panels can be a rewarding investment, offering both environmental and financial benefits. However, before diving in, it’s crucial to carefully consider several factors to ensure a successful and efficient solar energy system.

This article will guide you through the key aspects to ponder, from assessing your home’s suitability to navigating financial considerations and choosing the right equipment. By understanding these factors, you can make an informed decision about whether solar power is the right choice for you and your home.

  1. Suitability of Your Home

Before deciding on solar energy, it’s essential to assess whether your home is well-suited for this technology and to explore the best solar panels available. Here are crucial aspects to consider:

Roof Characteristics:

  • Orientation: South-facing roofs in the Northern Hemisphere generally receive the most sunlight throughout the day, maximizing energy production.
  • Pitch: The angle of your roof plays a role. While a tilt between 35 and 40 degrees is ideal, most roofs between 10 and 60 degrees can still work effectively.
  • Size and condition: Ensure your roof has enough space to accommodate the desired number of panels and is structurally sound to support their weight.
  • Shade: Existing or potential shade from trees, buildings, or nearby structures can significantly impact solar panel output. Analyze your roof’s shading patterns throughout the day to assess its suitability.

Energy Usage:

  • Look at your average monthly electricity bills and think about any expected changes in how much energy you’ll need in the future. 

Evaluating these factors helps make sure your solar system will produce enough power for your home’s needs.

  1. System Design and Installation

Choosing the right equipment and finding a qualified installer are crucial steps for a successful solar panel system. Here’s a breakdown of the key aspects to consider:

Types of Solar Panels: 

  • Monocrystalline: These panels offer the highest efficiency but come at a slightly higher cost.
  • Polycrystalline: Less expensive than monocrystalline, they offer good efficiency but may require slightly more space.
  • Thin-film: These lightweight panels are flexible and suitable for various roof types, but their efficiency is generally lower.

Consider factors like efficiency, budget, available roof space, and aesthetics when choosing the type of panel that best suits your needs.

Inverters and Other Equipment: 

  • Inverters: This essential component converts the direct current (DC) electricity generated by the panels into usable alternating current (AC) for your home. Choose an inverter with a capacity that matches your system’s overall power output.
  • Additional components: Depending on your needs, you might consider batteries for backup power during outages, monitoring systems to track your energy production, and specialized mounting systems for specific roof types.

Choosing a Qualified Installer: 

  • Experience and certifications: Look for installers with a proven track record and relevant certifications, ensuring they meet industry standards and safety regulations.
  • Online reviews and recommendations: Research online reviews and seek recommendations from friends or neighbors who have installed solar panels.
  • Multiple quotes and comparisons: Obtain quotes from several qualified installers and compare their proposals carefully, considering factors like equipment offered, warranties, and installation costs.

By carefully evaluating these aspects, you can make informed decisions about the equipment and installer best suited for your solar panel system.

  1. Financial Considerations

Setting up solar panels requires a considerable upfront cost, yet the prospects for long-term savings and economic advantages are significant. Below is an analysis of the primary financial factors to take into account:

Costs of Installation: The upfront cost of a solar panel system can vary depending on several factors, including:

  • System size: Larger systems generate more power but come at a higher cost.
  • Equipment type: Premium panels and additional components like batteries can increase the price.
  • Labor and permitting: Installation costs can vary depending on your location and the complexity of your roof.

According to the Solar Energy Industries Association (SEIA), the average cost of a residential solar panel system in the United States in 2023 was USD$3 per watt, before federal tax credits. This translates to a USD$15,000 system for a 5-kilowatt (kW) system, which is a typical size for many homes.

Potential Savings and Incentives:

  • Installing solar panels can significantly reduce your electricity bills over time. The SEIA estimates that a typical homeowner with a 6 kW system in the US can save an average of USD$1,400 per year on their electricity bills.
  • The federal solar Investment Tax Credit (ITC) currently offers a 30% tax credit on the cost of installing a solar panel system. This credit can significantly reduce your system’s upfront cost.
  • Many states and local governments offer additional rebates, tax breaks, or other incentives for solar energy adoption. Research available incentives in your area to maximize your savings.

Carefully evaluate your individual circumstances, including your electricity usage, local incentives, and financing options, to determine the potential financial payback period for your specific situation.

  1. Warranties, Maintenance, and Impact on Property Value

While the core aspects of suitability, system design, and finances are crucial, here are some additional factors to keep in mind:

  • Inquire about the warranties provided by the installer, often covering workmanship and potential installation issues.
  • Solar panels require minimal maintenance, but occasional cleaning and performance monitoring are recommended.
  • Studies suggest that homes with solar panels can potentially sell faster and for a higher price compared to similar homes without them.
  • The increased value can be attributed to factors like lower electricity bills, environmental benefits, and growing consumer demand. 

Consulting with qualified solar professionals can help you navigate these considerations and ensure a smooth transition to solar energy for your home.


Tapping into solar energy can be a valuable addition to your home, providing both financial advantages and environmental benefits. However, carefully considering various factors is crucial before taking the leap. Assessing your home’s compatibility, researching various system layouts and setup choices, and understanding the economic considerations will help you decide if solar energy suits your needs.
