The Cooling Effects Of Solar Panels
Since solar panels are above the roof, they help keep the roof cool from the harsh rays of the sun. They do this by absorbing the sunlight that would otherwise fall directly onto the roof. There is also a space between the panels and the roof where air can flow to help cool underneath the panels. Since the solar panels effectively act like a shade tree over the roof, they not only help keep the roof safer from falling limbs and debris, but according to a study done by UC San Diego, they help reduce the temperature inside the home up to nearly 35% or more.
What Else Should I Know
The pitch of your roof and the direction it faces both play into how solar panels are mounted. Usually, they should rest at a 20 to 30 degree angle. Most solar panels arent attached onto the roof itself, but on mounted rails. Panels dont move they dont have moving parts, and dont need regular maintenance. Solar installers add sealants to fill in the gaps, and the mounts are surrounded by flashing, or coverings, that add an extra barrier between the mounts and the weather.
In case there is a problem with the roof, you can remove the panels easily. It would take hurricane level winds to pull up solar panels and have them take roof shingles with them! So as long as solar panels are securely attached to rafters below your roof shingles, theyll stay put. If youre still concerned, there are plenty of ways to maximize a roofs durability, like extra flashings and fasteners that help prevent any leaks or hazards.
Do Solar Panels Affect Roof Warranty
If you have correctly installed roof-mounted solar panels, they should not affect any existing warranty. Still, its wise to check your existing warranties to verify that installing solar panels will not void them.
Typical roof warranties include a warranty on the materials and an installers warranty. These guarantee reliable materials and correct installation, respectively.
The addition of solar panels should not affect this because it does not change the material or its installation. The only real modifications being made are the holes drilled into the roof. When done correctly, all warranties should still be valid. Your existing warranty may even have provisions for solar panel installation.
Also, it is important to look at warranty options for the solar panels themselves. Since they are an addition to your roof and will take the brunt of the weathers effects, you should consider the quality of the solar panels and the guarantee they come with. If they are durable, long-lasting and correctly installed, they take some of the pressure off your roofs warranties because you are less likely to have roof damage.
In general, you can solve or avoid any possible problems with roof-mounted solar panels and your roofs warranty by working with professional roofers and solar panel installers.

Will Installing Solar Panels Cause My Roof To Leak
No, the chances of developing a leak in your roof do not go up with the addition of panels on your roof. Some mounting equipment does penetrate your roof. Usually this type of equipment is used to mount solar panels on residential asphalt shingled roofs. If this is the type of system you are considering, it is not something to worry about. Special fasteners have been developed that create a watertight seal on every penetration site.
There are also many types of mounting equipment available today that do not require any penetration of your roof. It is important to use a quality solar installer who is familiar with the mounting equipment that will be used on your roof. It is also a good idea to understand the warranty that comes with your installation and to inquire as to who is responsible in the unlikely case that any type of leak does develop.
Is My Roof Ready For Solar
Before installing anything, its a good idea to call a roofer anyway to inspect it and see if there is any preexisting damage. Go through your documents about your house and find out how many years youve got left on your roofs warranty. You want a roof in good condition before installing panels, so if you notice any kind of mold, rot, or leak beforehand, you need to get it fixed. If you need to replace the roof within the next five years, put in the new roof and solar panel system at the same time.
Remember, solar is an ROI positive investment not a burdensome cost. The Lawrence National Laboratory and the Department of Energy have shown that homes with solar sell faster and for significantly more money!

How Can Solar Panels Extend The Life Of Your Roof
Solar panels are more durable than other roofing materials. This is because they have no moving parts and can withstand high winds and heavy snow loads. Solar panels usually last about 25-30 years, depending on maintenance.
When added to your awning, this material can extend the life of your roof. Solar panels protect your roof from the suns rays. These boards absorb the sunlight usually directly absorbed by your shingles. This helps prevent them from bleaching and drying out.
Another way the solar panels protect your roof is by cooling it down. Air flows between the panels and your awning, reducing the temperature inside by about 38%. The cool air also allows your roof shingles to work more efficiently.
The durable material protects your awning from inclement weather, such as snow. With fewer repairs needed, your roof will last longer.
The Benefits Of Solar Panels
One of the main benefits of solar panels is it saves you money by lowering your electricity bill. The average household could save around $1,390 per year on their energy payments.
Besides the savings, solar panels are also beneficial to the environment. They use a renewable source of energy instead of fossil fuel. This reduces the emission of greenhouse gases into the air. In 2019, power plants burning coal, natural gas and petroleum fuel accounted for 99% of the U.S. electricity-related carbon dioxide emissions. Using solar panels can also slow down climate change.

Advantages Of Flat Roof Solar Panel Installation
There various considerations when installing solar panels on a flat roof. But there are many benefits of installing panels on the flat roof. These are:
1. Easy to Access
It is easy to access a flat roof, and it reduces the chances of a fall. For this reason, it is easy to install the solar panels as the movement for installers is easier. The maintenance is also easy as you do not need special equipment to access the roof.
2. Doesn’t Affect a House’s Aesthetic Appeal
When you purchase a home, there may be guidelines from the homeowners association about its appearance. Also, you may have a specific design that you want to maintain. Often, the panels are rarely seen from the street when installed on a flat foot. As a result, your neighbors will not complain about your solar panels being an eyesore.
3. Tilting Your System for Maximum Sunlight
When an installer is designing a solar system for installation, they take the roofs angle into account. Ideally, roof panels should face south at an angle equal to the latitude of the location. Also, some sloped rooftops tend to be steeper, producing less electricity as a result. Such factors can lead to a reduction in power generation over the years.
If you have a flat roof, you can avoid such variables as they offer flexibility. When installing the panels, you are free to orient them to face south. Additionally, you can angle the system regardless of the direction your roof faces. As a result, you can maximize your energy production.

Implication Onto Electricity Bill Management And Energy Investment
There is no silver bullet in electricity or energy demand and bill management, because customers have different specific situations, e.g. different comfort/convenience needs, different electricity tariffs, or different usage patterns. Electricity tariff may have a few elements, such as daily access and metering charge, energy charge or peak demand charge . PV is a promising option for reducing energy charge when electricity price is reasonably high and continuously increasing, such as in Australia and Germany. However, for sites with peak demand charge in place, PV may be less attractive if peak demands mostly occur in the late afternoon to early evening, for example residential communities. Overall, energy investment is largely an economical decision and it is better to make investment decisions based on systematical evaluation of options in operational improvement, energy efficiency, onsite generation and energy storage.

Unlike a roof array, you can adjust the panel angles on ground-mount arrays to better absorb sunlight.
Ground-mount systems can be tilted at an optimal angle, which varies depending on how far south or north you are, explains Mike Grunow, marketing director for manufacturer Trina Solar. An angle suitable in Texas is different than one in Minnesota because of their proximity to the equator. When you have a roof array, the angles are limited because you have to consider how much wind the panels could catch.
Ground-mount solar is also relatively simple and fast to install, requiring only light trenching to secure the racking system and a small crew to fasten the panels.

To Protect Yourself Screen Out Lousy Solar Installers
Theres no guarantee that you wont have problems with your solar installation, and even the best companies make mistakes. However, good companies will make things right, unlike the examples above.
There are simple things that a consumer can do to protect themselves. For one, many states allow you to check a companys contractor license online and see if they have any complaints on record. If you find a complaint, think twice about hiring that company.
As an example, Tesla Energy has numerous citations in California for issues such as departing from trade standards and not having permits for a project. Any company with a record like that is excluded from The Solar Nerd network.

Try To Fix The Damage Instead Of Buying A New One
It is not wise to throw the solar panel on minor damages. You can manage to repair it for minor impact damages from hailstones. If the damage is on the frame, they are available in the market, and you can replace it yourself. Before doing any repairs, read the warranty terms for the solar panel damage. Most solar panel brands do not cover the physical damage, but you can get a replacement plan on some fractions of the solar panel’s total price.
If you have experience in the repair and maintenance of solar panels, you can do it by yourself. Otherwise, you can hire a professional who can repair the solar panel glass or even the solar cells if a few of them have any damage from a hailstorm.

Solar Panel Cooling Research From Uc San Diego And France
A couple studies on the effect of solar panels on the temperature of rooftops and the urban environment have been done by researchers in France and UC San Diego.
The French researchers used modelling to demonstrate that the combined effects of the four mechanisms described above not only make rooftops cooler during the day, but the cooling effect continues at night. In addition, the combined effect of many rooftop solar deployments can reduce the urban heat island effect: solar panels can help to keep not just homes but entire cities cooler.
At UC San Diego, researchers examined a laboratory building on campus that has solar panels. Collecting data with a thermal imaging camera over three days, the researchers found that the ceiling underneath the solar panels was about 5 degrees cooler compared to a section of ceiling that wasnât covered with panels.
Their estimate was that the solar panels reduced the amount of energy reaching the roof by 38%. Over the life of the panels, the researchers estimate that this cooling effect adds an additional 5% energy benefit to the system. For a building owner, this is a great âfreeâ bonus of having solar panels.
