2021’s Best Home Solar Mounting Systems

By Solar Panel Installation Process No Comments

Solar panels and backup batteries get all the attention. But there’s another important piece of equipment to the home solar equation: mounting systems.

These sturdy little structures hold it all together. There are different options available depending on your roof type.

Some secure your solar panels to the roof, or elsewhere on your property if you don’t have the roof space. Did you know some specialized mounting systems can even maximize your system’s production?

Here are some of the best solar mounting systems for home solar.

Classic Roof-Penetrating Solar Racking

Rooftop-penetrating racking systems have been used since the dawn of solar power.

Solar installers drill holes and secure the racking system in place on your rooftop. This is done carefully and sealed well to prevent leaks. Most solar installers (and the ones you want to work with) include leakage warranties to ensure against issues.

Some of the top companies offering penetrating solar mounting systems for traditional composite or asphalt rooftops are IronRidge and Unirac.

Specialized Solar Mounting Systems

If your home has a more unique rooftop, like Spanish or clay tiles, or a metal roof, penetrating solar might not be a good idea. Tiles can break, and metal rooftops with seams are better fitted with clamps, rather than drilling into the roof.

Quickmount PV has a great solution for both of these rooftops. Metal mounts in the shape of the tiles create a solid base for the racking system. These metal tiles only replace specific sections needed for the mounting system, so you keep your beautiful roof.

SnapNRack offers a great standing seam metal roof mounting system that doesn’t require any drilling. Clamps easily allow installers to mount the system onto the metal rooftop.

Solar Ground Mounts with Tracking

Some homeowners opt for solar panels mounted on the ground or at the top of a post on their property. These are great options if there’s not much roof space.

Another advantage is the possibility of getting a solar panel racking system that can tilt as needed to follow the sun. This can improve how much power you get from your panels, as they’re always in the optimal position.

How To Choose The Best Solar Panels in 2023

By Solar Panel Installation Process No Comments

Solar panels last a very long time and technology is always improving.  How do you decide which panel is the right fit for you?  Should you pay more for a brand name?  Is there that much of a difference in quality and longevity?  Which panel will perform the best in the long run?  There are many elements to consider.

When It Comes To Solar Panels, Every Home Is Different

Solar panels are not one size fits all.  They are chosen based on their specific application.  Every home solar system is custom designed.  For example, an expensive high-efficiency panel may perform just as well as a standard or economy panel under certain circumstances.  Bigger is not always better.

There are numerous variables to consider when designing a solar system for a residence. For example – number and age of occupants, roof tilt, type of roof, number of trees in the vicinity and what type, age of home, etc.  Which solar panel you choose depends a lot on these variables.  

Each type of panel performs differently in different conditions. So considering these variables when choosing a solar panel for your home is important.  A design expert will do this for you during your consultation.  When you meet with a solar consultant, they should ask you questions and closely examine your roof before recommending a specific type or brand of panel.  

This tells you that they are looking out for your best interest and not upselling you to a specific high-cost brand.  Many homes have roofs compatible with excellent, high performing, low-cost panel options.

Inverter Compatibility

Solar panels and inverters work together to form the main components of your solar system.  Some photovoltaic panels are compatible with only specific types of inverters, some with all inverters, etc.  Your panels and inverter must fit together like puzzle pieces. The type of system your home needs determines which inverters and panels are an option for you.  

Doing a little research into inverters will help you determine which panels are right for you.  See our article about different types of inverters, optimizers, and microinverters here.

Choosing the Best Solar Panels

Now that you’ve done the necessary research, you are ready to compare brands and types of solar panels.  When determining which solar panel is right for you, there are many things to consider.  Let’s break it down into a few simple categories:

Solar Panel Warranties 

The various types of warranties and guarantees can be confusing. A product warranty covers the solar panel in case of a manufacturing defect. Typical solar panel lifespan is quite long. Most product warranties are anywhere between 10-25 years. This covers issues such as defects in the panel, premature aging, etc.

Solar Energy Performance Guarantee

The second type of guarantee you should look into is the panel’s performance guarantee.  Panels lose a very small amount of efficiency per year.  The loss is on the order of less than one percent (typically 0.4 to 0.7%).  A performance guarantee assures you that your panels won’t degrade any faster than that.  Basically, it ensures your panels will perform at peak levels for their lifetime.  These guarantees are usually around 20-25 years.

Solar Panel Efficiency

The efficiency of a panel tells you how well it converts sunlight into electricity.  This is not as important of a metric as you may think. Modern solar panels all have very high efficiency, typically around 20%.  The differences between panel efficiency ratings are negligible for the cost increase.  The only time this might be of importance is if you are trying to maximize production in a small available space.  

Solar Panel Wattage

It is easy to confuse efficiency with wattage.  A wattage is a unit of measure denoting the potential electrical output of a panel under ideal circumstances.  The higher the wattage of a panel, the more electricity it can potentially produce for your home. Higher wattage panels are ideal for smaller spaces that need higher production. However, they often come at a higher price.  So it’s not always best to invest in higher wattage panels if it’s not necessary for your home.  Additionally, sometimes higher wattage panels are physically bigger.  This may mean fewer panels can fit in a certain space, thereby negating the advantage of having a higher wattage.

Solar Panel Aesthetics 

As more people are going solar, the need for well-designed panels is becoming a higher consumer demand.  Many homeowners want black panels, but there are various types of black panels.  Most silicone cells are either dark blue or black.  These cells are the squares that make up the face of the solar panels.  The space between these cells is where you can see the back sheet.  Having a black backsheet makes for a much sleeker, all black look.  Finally, considering the frame color is important.  Most solar panel frames are anodized aluminum and come in silver or black. Choosing a black frame can enhance the look of your system greatly.

There are many elements to consider when deciding which solar panel is best for your home and your needs.  The best way to determine which options may work for you would be to talk with one of our solar specialists.  They are well versed in the complex nature of solar system design.  They can advise you on which panels will produce the most energy, most economically, and with the most aesthetic system design.
