MAGNETIC Solar Panel Mounts at 70 MPH! CATASTROPHIC FAIL, or Epic Win?

Before proceeding with a solar panel install there are certain things you should know in order to make sure they’ll be suitable for your home and you’ll be getting the best from your panels.

Most of these things the sales rep will tell you automatically before you buy. However there are things that he or she may not tell you and these can cause major headaches, or worse still cost you additional money.

It’s not that the rep doesn’t want to tell you everything. But each job is different and therefore each job will have slightly different nuances that will need to be considered.

So when the rep is there ask them as many questions as possible, even if you think they’re silly, ask them anyway.

Flat Roofs Are Another Special Case

Earlier I said that solar panel mounting systems are attached to a roof using footings that are bolted to the rafters. One special case where this isnt always true is a flat roof.

With a flat roof, contractors can use the same mounting systems they would with a pitched roof, but they also have the option of a ballasted rack.

Ballast is simply a heavy weight – often concrete blocks – that is used to anchor a racking system in place. These weights keep the solar array in place without the need for bolts or any holes in your roof. This is an attractive option, but it does have the disadvantage of placing additional stress on your roof. Which of these options is best for your home is best determined by your contractor, often in consultation with a structural engineer.

What Happens If You Need A New Roof

If you need to replace your roof after you have solar panels installed, you will need to remove and reinstall the solar panels.

Your solar installer should take a look at your roof before beginning the project to ensure its in good shape. If you need a new roof, youll want to get that out of the way before installing the solar panels.

While a new roof is never something we get excited about buying, your future self will thank you. If you need a new roof or repairs to the roof that need to be made, your solar panels will have to be removed and reinstalled. This should cost less than the actual installation itself but is best to be avoided if possible.

How Are Solar Panels Installed On A Steep Tile Roof

If your tile roof is steep, the process of how to install solar panels on it will be slightly different from how we would do so if they were flat since there are more variables involved.

First off, how steep is your roof?

If its less than 30 degrees, then you will need to take extra precautions in how you install the panels so that they dont slide right off.

The installer would have to be very careful when attaching them and there may not even be enough room for all of them on a tile roof this steep.

In some cases, they may even install them on different sections of the roof that are more manageable and then tie it all together with a tracking system.

If your tile roof is steeper than 30 degrees but not too steep to where there isnt room for all of the solar panels on it, you have an option of how to have your tiles mounted.

Find A Good Spot On The Rv Roof

Spanish Tile Roof Mount Solar Panel Installation in Roswell, NM

When deciding where you should install the solar panel on your RV roof there are a few things you will need to consider.

First, where are the RV batteries and where will the solar charge controller be?

You want to put the panel on the part of the roof thats closest to where the cables will need to go.

In the case of our travel trailer that was the front of the RV since the batteries and the charge controller were located on the tongue.

You also want to think about the other things on the RV roof. If you put the panel right next to the RV AC it might block the sun.

Putting the panel in a spot where it will get the most sun for as long as possible is important.

If possible you also want to be able to find where the roof supports are so you can screw the solar panel into a solid spot.

We found that finding the roof studs was harder than we thought it would be. The stud finder didnt work because there are multiple layers of rubber and wood on an RV roof.

We did the best we could and so far we havent had any issues with the solar panel staying on the roof.

Since both roofing screws and butyl tape was used to mount the panel a lot is keeping it in place.

Quick Installation Of Pv Panels Distribution Boxes And Other Details

Dont let the fear for a long installation restrain you from buying solar panels. The following example will prove this is a quick job. When consulting a specialized company, the installation of 10 photovoltaic panels will only take a few hours. On the first day, aluminum profiles were installed within an hour and PV panels were mounted in them. The cables were pulled into the technical room, where they were installed in switch cabinets the next day .

This quickly installed system was used for local energy production, which in this case is used for heating and hot water without having to pay suppliers. Thanks to the PV panels on the roof this household can provide cheap electricity production which results in a lower bill and reduce their dependence on electricity prices.

Your Roof Required Condition For Panels

Your roof must be in good condition to support PV panels. The average weight of most residential solar panels is around 40 pounds.

These panels plus mounting hardware add about 3 to 4 pounds per square foot of load to your roof. This weight isnt much but is capable of destabilizing roofs that are in poor condition.

PV modules are also flat, making them susceptible to strong winds. For example, the wind might blow off your panel if you anchor it to a deteriorated or rotted roof.

Always inspect your roof for potential damages before you mount solar panels. Vital aspects you should check include:

  • Shingles
  • Flashing

Watch out for damaged trusses, leaks, mildew, streaks, and cracked shingles.

Remember, a damaged roof lacks the structural integrity to support any additional load. Consider hiring a roofing expert to assess your roof condition.

What Are Solar Shingles

Solar panel shingles are a type of solar panel designed to look like traditional asphalt roofing shingles. Solar shingles are made of thin-film photovoltaic cells laminated onto a backing material, thus are less visible on the roof and can provide a more aesthetically pleasing option for some homeowners. Solar shingles for your roof are also easier to install than traditional solar panels.

East/west Mounting Solar Panel Systems

Special Roof – Torch Down / Bitumen Solar Installation

Although an East/West solar panel system works similar to a console bin solution, an East/West solar panel system can generate more power. This is because the solar panels lye back to back without any gaps between the rows for shading. In fact, according to German manufacturer Renusol, an east/west system can generate around 30 percent more solar power than south-facing systems. Making an east/west mounting system the perfect solution for flat roofs with limited space. Furthermore, by fitting the solar panels back to back, they are more air resistance and require less ballast to secure them into place

Solar Panels On Flat Roofs Can Be Installed At The Perfect Angle To Maximize Your Electricity Production

Solar installers designing PV systems for standard sloped roofs have to incorporate roof angle and roof orientation into their system designs. Ideally, solar panels will be installed facing south at an angle equal to the latitude where they are located. If you have a roof that faces east or west, or can only install solar panels on the north side of your roof, your system will produce less electricity on a day-to-day basis. Additionally, some sloped roofs are steeper than others, which can result in less-than-ideal electricity production. While this doesnt mean solar isnt worth it, these considerations can decrease your total 20-year electricity production.

Flat roofs offer more flexibility in terms of your solar panel system design. If you install solar panels on your flat roof, they can be oriented to face south and mounted at the correct angle regardless of which direction your home faces. Both of these specifications ensure that your system can be optimized for maximum electricity production. At the end of the day, that means a better-performing system for your home or business.

Whats The Difference Between Buying And Leasing

Theres a big difference between leasing and buying solar panels. Leasing solar panels is like renting them. Youll be paying a monthly cost to have them on your home without ever truly owning them.

Buying solar panels may often require a loan to which you will have a monthly payment, but that loan will eventually go away, and youll own the panels and all of the energy savings they bring. When speaking to a solar representative, talk through the benefits of both leasing and buying so that you can decide whats right for you.

Consider Installing Shingle Under The Solar Array

Many solar installers prefer to replace tiles under a solar array with shingles instead of installing the solar panels directly on a tiled roof.

Its easier to mount solar panels on shingles. But you must ensure the edges where the roof tiles meet the shingle seals shut. You dont want water doesnt permeate into your roof, causing unwanted leaks or damage.

Can Solar Panels Damage Your Roof

Most people are wary of holes in their roofs – and thats fair. With the exception of standing seam metal roofs and flat roofs, penetrations in the roof are required to properly mount the solar panels.

However, a properly installed solar system should not cause any leakage, even if penetrations are needed. The industry has been installing rooftop solar for a few decades, and proper measures have been developed to minimize the risk of any water damage happening because they had solar panels installed.

Theres even an added benefit – your solar panels can actually protect your roof.

Solar panels act as a shield to the common and unavoidable wear and tear. Theyre durable and built to withstand much of what Mother Nature throws their way, keeping your roof dry and clean underneath.

The important thing to note is to work with a reputable solar installer. This will ensure youre backed by their warranties, and theyll work to maintain the warranty of your roof.

    Choosing The Roof Location For Mounting The Solar Panels

    You need to carefully decide what part of your roof youll install the solar panels on. This location is primarily dictated by two factors.

    I. Region Your House is in

    Knowing which region your house is in will give you an idea about the amount of sunlight youll potentially get. This detail affects the number of solar panels youll ideally need and the optimal tilt and location for them.

    II. The Direction of the House

    The direction your house faces affects which part of it receives the most sunlight. Since your goal is to maximize energy absorption, knowing the direction will also let you know which location receives the most sunlight.

    Solar Panels On Flat Roofs

    Solar panels can just as easily be found on flat rooftops as on sloped roofs.

    The solar panel installation process for flat roofs is usually much simpler than on sloped roofs since its easier to move around, leading to a quicker finish.

    Solar installations on flat roofs dont require the penetration mounts that sloped roofs need for the panel system to remain secure. Alternatively, weighted mounting systems are used for flat roofs, which dont require drilling into your roof. This type of system eliminates the need for holes and uses gravity instead to ensure your solar panel system is stable and secure.

    However, since flat roofs clearly dont have an angle, tilt-up brackets are used to keep your system angled at 30 degrees.
