How to Choose the Right Solar Panels for Your Home

Updated: Sep 5, 2023

Solar energy is a clean, renewable, and affordable way to power your home. But with so many types of solar panels available on the market, how do you know which one is right for you? In this blog post, we will guide you through the main factors to consider when choosing solar panels for your home, such as efficiency, cost, durability, and aesthetics.


Solar panel efficiency is a measure of how much sunlight a panel can convert into electricity. The higher the efficiency, the more power you can get from a given area of roof space. However, higher efficiency also comes with a higher price tag. Therefore, you need to balance your energy needs and budget when deciding on the efficiency level of your solar panels.

The most common types of solar panels are monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are made from a single crystal of silicon and have the highest efficiency, ranging from 17% to 22%. Polycrystalline panels are made from multiple silicon crystals and have lower efficiency, ranging from 15% to 17%. Thin-film panels are made from thin layers of different materials and have the lowest efficiency, ranging from 10% to 13%.


The cost of solar panels depends on several factors, such as the size, type, quality, and brand of the panels. Generally speaking, monocrystalline panels are the most expensive, followed by polycrystalline panels and thin-film panels. However, the cost of solar panels also varies depending on the installation company, the location, and the incentives available in your area.

According to EnergySage⁴, a leading online marketplace for solar quotes, the average cost of solar panels in the U.S. in 2021 was $2.81 per watt. This means that a typical 6-kilowatt (kW) system would cost about $16,860 before any tax credits or rebates. However, this is just an estimate and the actual cost may vary depending on your specific situation.


Solar panels are designed to withstand harsh weather conditions and last for decades. However, not all solar panels are created equal when it comes to durability. Some factors that affect the durability of solar panels are the quality of materials, the manufacturing process, the warranty period, and the maintenance requirements.

Monocrystalline panels are generally more durable than polycrystalline or thin-film panels because they have fewer defects and impurities in their silicon cells. They also tend to degrade slower over time and lose less efficiency. Polycrystalline panels are slightly less durable than monocrystalline panels because they have more cracks and gaps in their silicon cells. They also tend to degrade faster over time and lose more efficiency. Thin-film panels are the least durable of all because they are more prone to damage from moisture, dust, and temperature fluctuations. They also degrade much faster over time and lose more efficiency.

The warranty period of solar panels is another indicator of their durability. Most solar panel manufacturers offer two types of warranties: a product warranty and a performance warranty. The product warranty covers any defects or malfunctions in the panel itself for a certain period of time, usually 10 to 12 years. The performance warranty guarantees that the panel will produce a certain percentage of its rated power output for a certain period of time, usually 25 to 30 years.


Solar panels require very little maintenance because they have no moving parts and are designed to be self-cleaning. However, it is still advisable to inspect your solar panels regularly and clean them if necessary to ensure optimal performance and longevity.

The main thing you need to do is to remove any dirt, dust, leaves, bird droppings, or other debris that may accumulate on your solar panels over time. These can block some of the sunlight from reaching your solar cells and reduce their efficiency. You can use a soft brush, a cloth, or a garden hose to gently wipe or spray away any dirt or debris from your solar panels. You should avoid using any abrasive or harsh chemicals that may damage your solar panels.

You should also check your solar panel wiring connections and terminations for any looseness or corrosion that may affect the flow of electricity. You should also check your roof penetrations and weather sealing for any leaks or cracks that may cause water damage or fire hazards. If you notice any problems with your solar panel system components or wiring, you should contact your installer or manufacturer for repairs or replacements as soon as possible.


Solar panels can also affect the appearance and value of your home. Some people may find solar panels attractive and appealing because they show environmental awareness and energy independence. Others may find them unattractive and intrusive because they clash with the architectural style and color of their home. Therefore, you should consider your personal preference and the aesthetic impact of solar panels on your home before installing them.

One way to improve the aesthetics of solar panels is to choose a type and color that matches or complements your roof. For example, monocrystalline panels have a uniform dark color and rounded edges that may look sleek and modern on a flat or metal roof. Polycrystalline panels have a bluish hue and square edges that may look more natural and traditional on a shingle or tile roof. Thin-film panels have a black or brown color and can be flexible or rigid, depending on the material. They may look more discreet and integrated on a curved or irregular roof.

Another way to improve the aesthetics of solar panels is to choose a mounting system that minimizes the visibility and protrusion of the panels. For example, flush-mounted systems attach the panels directly to the roof surface with minimal gaps and hardware. Tilted-mounted systems raise the panels at an angle to the roof surface with brackets and rails. Ground-mounted systems place the panels on a structure on the ground instead of on the roof.


Choosing the right solar panels for your home can be a daunting task, but it can also be a rewarding one. By considering the factors of efficiency, cost, durability, maintenance, and aesthetics, you can find the best solar panel option for your home that meets your energy needs, budget, and preferences.
