(Video) Exploring Tesla Solar Roof vs. Solar Panels

For years, the traditional approach has been based on installing the rather heavy, crystalline solar panels on top of an asphalt shingle roof, an oil-based roofing system with a relatively short lifespan.

This approach has worked for a while, however, roof penetrations, needed for the installation of a solar panel mounting or racking system, made to an asphalt shingle roof, can increase the likelihood of premature roof leaks down the road, and further shorten the already short lifespan of an asphalt shingle roof.

Penetration/Drilling free Solar Roofing Alternative

With the latest technological advancements and innovations, you can now get a commercially viable thin-film PV solar panels offering revolutionary simplicity; Thin-film PV solar laminates are light-weight, easy to install, require no penetrations made to your roof and can last for quite a long time. Read more about it below:

Integrating your Standing Seam Metal Roof with Thin-film PV Solar Laminates

Simplicity is the ultimate sophistication. One of the latest technological innovations in solar metal roofing is the integration of thin-film PV solar laminates with standing seam metal panels using a peel and stick method.

Did you know? Fabral has recently discontinued their Flex 02NS – Thin-Film PV Solar Laminates. However, you can now get high efficiency PowerFLEX®+ Flexible Solar Panels from Global Solar.

Pros and Cons of Crystalline PV Solar System coupled with an Asphalt Shingle Roof

Before we delve into the benefits of thin-film photovoltaic solar laminates, let’s examine some of the downsides of using the traditional combination of bulky PV solar panels installed on an asphalt shingle roof.

Here is Why you may want to think twice before installing a PV solar power system on an asphalt shingle roof…

The main problem associated with general/conventional PV solar roofing systems that you can often see on some homes and buildings around the country, is the fact that an asphalt shingle roof is likely to fail much sooner than the solar panels will.

Picture a scenario in which a homeowner spends a large amount of money to install a new crystalline PV solar power system on his/her existing asphalt shingle roof. It is likely that in several years the roof will fail, due to roof leaks caused in part by roof penetrations made during the solar system installation.

When such a situation occurs, homeowners will be faced not only with earlier than expected re-roofing expenses, but also with having to pay for a complete removal of solar panels, and for their eventual re-installation.

What further complicates this situation, is that re-roofing work, and solar panel dismantling and re-installation MUST be coordinated and simultaneously performed by both the roofer and the solar integrator.

A roofer who is only paid for the installation of a new roof, will 99% of the time make solar panel dismantling and re-installation errors that could cause irreparable damage to the solar modules.

Bear in mind that roofing warranty will most of the time not cover damages to solar equipment, let alone all the possible short-circuit of the solar wiring situations.

The additional solar panel dismantling, and re-installation cost associated with these procedures can sometimes be just as high as the expected cost of a small new roof in some areas of the country.

If you think about it, electricians, unlike roofers, must be licensed. An apprentice electrician needs at-least 4 years of schooling/work experience. This is like an undergraduate degree. Master electrician needs another 4 years. Therefore, electricians usually charge $100-$125 per man-hour. You will need at least two electricians for this job, which will take a whole day to remove the panels, and another full day to put them back on.

The math is simple: 2 guys * $100/h * 8 hours * 2 days = $3,200.00, plus the building permit and inspection, and any possible parts and supplies that may be required.

Granted, home solar companies have laborers and installers who are more skilled at handling solar panels and have lower labor cost/rates than professional electricians, but it still may be tough to get a professionally trained solar crew on site just to properly dismantle and reinstall the existing solar panels while having to coordinate the project with the roofing contractor who is replacing the old roof. Good luck getting all that coordination work done on the cheap. Every project has expensive setup costs and opportunity costs for a busy contractor.

Let’s assume it costs $3,500.00-$4,500 to completely remove and re-install, re-connect and re-inspect crystalline PV solar panels on your roof. In some parts of the country, this is how much a small 1,000 sq. ft. roof might cost for labor and materials.

What are Thin-Film PV Solar Laminates?

Thin film PV solar laminates are lightweight and easy to install. They are made to fit standard standing seam metal panels. Thin-film PV solar laminates do not require any penetrations to be made to the roof and can be easily attached to standing seam panels using a revolutionary peel and stick method.

Thin-Film PV Solar Panels vs. Crystalline PV Solar Panels

Crystalline solar panels can generate twice the amount of electricity of the thin-film solar panels. However, crystalline panels are bulkier, and use a special mounting system, which requires roof penetrations. The only exception is a standing seam metal roof. You can attach an S-5 solar panel holding brackets to the raised seams of a standing seam roof.

Thin-Film PV solar panels are designed to integrate seamlessly with a standing seam metal roof. They have a very low profile, which can be a significant architectural factor. They can generate electricity even on cloudy days, in the absence of a direct sunlight.

Why Combine a Metal Roof with thin-film PV Solar Laminates?

Unlike the ubiquitous asphalt shingle roofs, modern metal roofing systems are made to last and can be considered permanent. They are manufactured using a significant proportion of recycled metal content and are fully recyclable themselves, hence qualifying them for LEED credits as a sustainable green building material.

When Metal Meets Solar, it is a True Match!

When a standing seam metal roof is installed by specially trained professionals, it will last for many decades, and thus can be a permanent platform for a solar roofing system whether it be the old school crystalline PV panels or thin film solar laminates.

Metal roofs combined with renewable energy technologies can create a perfect combination of lightweight, long-lasting, and affordable solution for Solar Electric and Solar Hot Water systems.

There are numerous benefits to having a metal roof combined with solar PV panels, and other renewable energy technologies. Longevity, durability, and cost savings that add up over time are just some of the benefits to name a few.

When comparing shingles vs. metal roofing you should also consider that a metal roof will help save our landfills from getting more old roofing shingles, petroleum-based products, being dumped there every time an old asphalt shingle roof gets replaced.

Metal offers a permanent and energy efficient roofing solution that can generate electricity when a metal roof is integrated with solar shingles roofing system; it uses thin-film PV solar panel technology in combination with conventional asphalt shingles.

However, the proponents of green and environmentally friendly building technologies are likely to be disappointed, because asphalt shingles underneath the PV solar panels contain petroleum. Further asphalt products are not going to last nearly as long as their metal counterparts.

This is an interesting time to consider adding a solar power system to your home because solar energy is no longer getting cheaper (due to a broader and ongoing price inflation ), while the range of available solar options for homes is continuing to expand.. Source: Global Solar Thanks to the advancements in solar technology, you can now opt for the so-called thin-film solar panel laminates designed to adhere to standing seam metal panels or to flat roof surfaces (membranes) like PVC, TPO, EPDM Rubber , without the need for any roof penetrations.. What’s in this guide: This guide compares innovative thin-film (TF) photovoltaic laminates to traditional PV solar panels with respect to balance of system (BOS) costs, pros and cons, available options, and more.. The current average cost of a residential PV solar panel system hovers between $2.80 and $3.50 per installed watt.. Source: Wood Mackenzie For example, today, a typical 6kW PV solar panel system costs approximately $18,000-$19,440 before the applicable federal tax credits and local incentives are applied.. Poly PV solar panels cost less per kilowatt hour than monocrystalline panels.. Efficiency: 13%-16% for polycrystalline silicon panels; 17% to 22% for monocrystalline silicon PV panels.. Amorphous silicon, while used in residential solar PV panels, is less efficient.. When you have a large rooftop area available for a TF solar PV system (since TF isn’t quite as efficient as monocrystalline PV).. If so, you should plan to install new asphalt shingles before adding solar panels, or you’ll be faced with shingles that are wearing out before the solar panels need replacing.. Thin film solar panels vs crystalline PV panels isn’t your only option.. With all the hype about Tesla Solar Roof, we’ve not seen many residential installations to date… However, today there are several compelling solar tile roof alternatives available from companies like SunTegra, 3-in-1 Roof , Luma Solar, CertainTeed (Apollo II shingles and tiles), and OneRoof by SunPower.

Trying to compare thin film amorphous silicon PV laminates with crystalline solar panels for a standing seam metal roof application is like asking who plays better baseball—the New York Yankees or the Boston Red Sox.

Trying to compare thin film amorphous silicon PV laminates with crystalline solar panels for a standing seam metal roof application is like asking who plays better baseball—the New York Yankees or the Boston Red Sox.. There are, however, two proven methods – thin film amorphous silicon PV laminates (shown below) and crystalline solar panels (shown above).. A standing seam metal roof has a life expectancy consistent with that of framed and laminate photovoltaic systems.. A 30-year power source on a 30-year roof, along with zero-penetration technology creates the most sustainable roof system available with alternative power generation, all without compromising the roof's warranty.. Variables including space, climate, sunlight and design aesthetics, along with price and product specification, should also dictate which is the suitable photovoltaic choice for a standing seam metal roof.. Crystalline panels, meanwhile, are attached to the roof using non-penetrating clamps that are secured to the roof's seams.. A crystalline system, requiring framing and clamps that attach to the seam of the standing seam metal roof, will cost more than an adhesive-backed photovoltaic laminate which can be applied directly to the panel of the standing seam.. But because it takes more laminate material to produce amounts of energy comparable to a crystalline configuration, more connections must be installed with the laminate system – negating any substantial installation savings from the simple peel and stick process.. Many standing seam roofs today are available with cool roof coatings that are ENERGY STAR approved and LEED compliant.. Englert Inc. sells a PV laminate product called SunNet and has been producing a standing seam product coated with SunNet Blue in an effort to match the color of the laminate to the standing seam material.. Many standing seam metal roofing systems meet the material requirement for these standards.. Homeowners contemplating the use of standing seam with PV laminates in hurricane areas should investigate which combinations of standing seam profiles and PV laminates meet the Miami-Dade code.. S-5!, a company that provides metal rooftop attachment solutions, has introduced a clamp for securing framed photovoltaic modules to standing seam metal roof systems.. If you want the soundest defense against the fury of Mother Nature then you should have an American Society of Consulting Engineers (ASCE) analysis to specify the most storm-proof construction, a weather tightness warranty from the roofing material manufacturer with onsite installation inspections, the services of a certified installation contractor who will properly install the roof and supervision by an architect with experience in metal roof and solar installation.

Thin-film solar panels have a promising future with many benefits over traditional panels. Explore the different types and applications now→

The first progress for Copper Indium Gallium Selenide (CIGS) thin-film solar cells was made in 1981 when the Boeing company created a Copper Indium Selenide (CuInSe2 or CIS) solar cell with a 9.4% efficiency, but the CIS thin-film solar cell was synthesized in 1953 by Hahn, H. In 1995, researchers at the National Renewable Energy Laboratory (NREL) embedded Gallium into the CIS matrix to create the first Copper Indium Gallium Selenide (CIGS) thin-film solar cell with a reported efficiency of 17.1%.. The first CIGS thin-film solar panel manufactured by NREL reported a 17.1% efficiency, but the most efficient one ever created reported an efficiency of 23.4% and was made by Solar Frontier in 2019.. Considering that thin-film solar modules only hold around 10% of the market, This is still quite popular as a thin-film solar technology.. The manufacturing process for GaAs thin-film solar cells is more complex than for regular thin-film solar cells.. Before comparing the different types of thin-film solar panels against crystalline silicon solar panels (c-Si), it is important to remark that there are two main types , monocrystalline silicon (mono c-Si) and polycrystalline silicon (poly c-Si) solar panels.. Considering the coefficient temperature and longer durability for thin-film solar panels, thin-film solar panels can be a better choice in the long run.. This technology integrates thin-film solar technology to provide a certain generation efficiency, which can be used just like with regular c-Si solar panels.. While c-Si solar modules hold the largest market share, efficiency for thin-film solar panels is growing and manufacturing processes are becoming cheaper, which could lead to thin-film solar panels becoming the norm for most installations.

One of the main drawbacks of the traditional way most solar panels are installed on residential properties is that it requires drilling through the roof,

Up until recently, the only way to install solar panels without drilling was if you had a flat roof but the good news is that a few innovative companies have created systems that let you install solar panels and don’t require drilling through the roof.. Fixing Solar Panels On A Metal Roof There are two products that are the most similar to solar panel arrays installed via drilling that can go on shingled tiles, the Z-Rack and Flat Direct.. As the wind blows over the roof, it creates a downforce that pushes the panels tightly to the roof.. Unlike systems that are drilled into the roof, Flat Direct maintains more gaps between panels to prevent the whole array from lifting during wind gusts.. Solar Flat can usually be installed on a traditional asphalt shingled roofing, but depending on your specific roof and location, some drilling might be required.. These panels are attached to the roof with an adhesive and work best on standard standing seam metal roofing panels, a durable and weather-tight roofing system.. If you are thinking of replacing your roof anyway, metal roofing combined with thin-film PV solar laminates could be a great option.. Luckily, there are a few more options for installing solar panels without drilling on a flat roof when compared to traditional sloped shingle roofing.. You can install solar panels on a flat roof using heavy metal plates or concrete to hold the array in place, again provided they are permitted by your building codes.. Another option is to use metal trusses that span the roof and are attached to the roof overhang to secure the solar array.. One last option to consider if you want solar power but don’t want to drill through your roof is not putting the panels on your roof at all.. If you have the space, you can mount solar panels on a racking system that lies on the ground instead of the roof.

Learn what makes thin film stand out from standard crystalline panels and find out when thin film solar is the ideal option for homeowners.

In this article we’ll dig into what makes thin-film stand out from standard silicon photovoltaic (PV) panels and offer some insight on when thin-film solar is an ideal option for homeowners and the residential market.. Amorphous Silicon (a-Si) – The second most popular thin-film option after CdTe, a-Si is the most similar technology to that of a standard silicon wafer panel.. When comparing thin-film panels to the standard solar panels more commonly used in the residential market, there are a few factors that clearly distinguish one from another: carbon offset , efficiency, roof space and installation cost.. A standard panel installation can significantly cut your electricity bills even if you have limited roof space, but thin-film needs to be installed on larger roofs to accommodate the increased amount of space necessary for the system.. As long as you are working with a company that provides a mounting solution for thin film, reduced labor costs are a hard selling point for a thin film installation over standard PV panels.. First Solar – The top thin-film manufacturer, First Solar dominates the CdTe technology space.. SoloPower is one of the world leaders in CIGS manufacturing.. If thin-film continues to scale in the commercial sector and penetrate the residential market, CIGS will be the technology that can achieve it.. Thus, the larger the system being installed, the more cost-effective it becomes as reduced installation costs offset the panel output losses due to lower efficiencies.. That being said, there is still an opportunity for thin-film in the residential sector: larger houses with adequate roof space can benefit from an economies-of-scale installation as well as the aesthetic benefits of the frameless and glass-on-glass thin-film models that are commonly offered by the leading manufacturers.

This article compares the basic application differences between thin-film and crystalline silicon technologies in terms of application

There is a competitive price advantage of Thin Film modules over Crystalline Silicon PV modules.. Despite the fact that the global thin film module production capacity have increased significantly since 2007, the price of crystalline silicon modules have sharply decreased.. The efficiencies of these two technologies are rapidly increasing while the price gap rapidly is narrowing.. For residential and commercial project developers (installers), there are a few topics that need to be considered.. An investigation on design constraints to be made by the PV designer, the usability and the visual properties to be considered by the project owner; though it’s up to the project developer to influence the project whether to go with Thin-Film modules or Crystalline-Silicon modules..

Thin-film solar panels are lower cost than silicon solar panels. Learn all about the pros and cons of thin film solar panels.

Thin-film solar panels are worth considering since they are cheaper than ordinary silicon solar panels.. To put it simply, thin-film solar panels are a type of PV panel belonging to the broader solar panel family.. This is how “thin-film” cells got their name.. High energy light excites the electrons in a semiconductor.. al.Silicon solar cells are made of N-type silicon and P-type silicon to direct electron flow.. Like silicon solar cells, thin-film solar cells are made of a sandwich of semiconductors.. Thin-film solar cells are typically less efficient than silicon solar cells, but it depends on the specific cell.. Thin-film solar cells maintain their efficiency better than silicon solar cells.. Thin-film cells are cheaper than silicon cells.

Ease of installation, durability, and environmental benefits are just three of the reasons to consider putting solar panels on a metal roof.

It’s easy to mount solar panels on a metal roof Solar metal roofs can host thin-film panels and standard PV panels Metal roofs are durable and can outlive your solar panels Solar panels can increase the cooling benefits of a metal roof Metal roofs and solar panels generate an eco-friendly home. There are a few alternative mounting options that make installing solar on a metal roof easier:. If you have a standing seam metal roof, your installer can attach panels using a mounting system that clamps onto the seams of the roof without having to make any holes.. As an added bonus, using this type of racking can speed up installation times (and lower your labor costs) because your installer won’t have to drill holes into the roof.. In addition to making the installation process easier, they have the added bonus of ensuring that your solar installation is completely watertight since your installer is simply replacing tiles on your roof to mount your panels.. Mounting company SnapNrack offers a unique solution for installing solar panels on a corrugated roof.. Waterproofing becomes a much more important issue with these types of mounting systems, as there will be actual holes in your roof to secure the racking system.. Thin film solar can only be installed on certain types of roofs, and standing seam metal roofs are an ideal surface.. MiaSolé, a California-based thin film solar panel manufacturer, markets their panels as an ideal option for properties with metal roofs.. You can read more about them in EnergySage’s company overview .. Homebuilders and contractors often tout the benefits of cool metal roofing (e.g. metal roofs coated with reflective paint) to keep your home cool in the summer and reduce your energy use.. As an added environmental benefit, unlike many other options, both solar panels and metal roofing materials are recyclable at the end of their lifespan.

We take a look at 5 emerging solar technologies that are expected to have the biggest impact on the industry over the next couple of years.

Floating solar farms (floatovoltaics) are cheaper to install and can produce more power than land-based solar panels due to the cooling effect of water.. Solar skins allow you to customize the look of solar panels for improved aesthetics.. The development of solar fabrics would allow for clothing that can generate solar power while you’re on the move.. The installation costs of floating photovoltaic panels are less than land-based photovoltaic panels.. Besides producing clean solar power, floating solar farms can help with water management.. Solar skins are a novel PV technology to integrate custom designs into solar panel systems.

Solar tiles are typically at least twice as expensive as solar panels. We'll help you work out if they're worth it for you.

On this page, we’ll tell you everything you need to know about solar roof tiles (or photovoltaic roof tiles), including typical costs and manufacturers.. Solar tiles can cost at least twice as much as solar panels.. For example, a 4 kW solar tile system will typically cost between £12,000 and £16,000 , while a 4 kW solar panel system usually costs £6,500 .. It’s difficult to estimate exactly how much a solar tile system costs, as it depends on 1) the size of your roof, and 2) what proportion of the roof you’d like to be covered in solar tiles.. Here are the typical costs of solar tiles compared to solar panels:. Solar tiles , also known as solar shingles or solar slates , are for people who want a solar-powered home without anybody noticing.. That’s right – solar tiles work just like solar panels (i.e. photovoltaic cells converting sunlight into electricity), but they’re made to look just like traditional roof tiles.. While solar panels are much cheaper and generally more efficient than solar tiles, they can sometimes protrude out and clash with the colour of the roof they’re placed on.. Instead, you have to replace your entire roof , which means dismantling it, and rebuilding it with a mixture of traditional and solar tiles (a 100% solar roof is possible, but it’s not cheap).. Unfortunately, the current options for solar tiles in the UK are limited – the only manufacturers are GB Sol , which creates blue solar slates in Wales, and Solecco Solar , which is based in Leeds (find out more below).. Instead, the company now produces integrated solar panels – the Sunstation Roof-integrated+ – which aren’t quite as subtle as solar tiles, but still sit more seamlessly on your roof than standard solar panels.. Are you wondering whether you should buy solar panels or solar tiles?. As mentioned previously, solar tiles generally cost at least twice as much as solar panels, so you’re really paying for the aesthetics.. The efficiency of solar tiles (i.e. how much sunlight they convert into electricity) tends to range between 10-20%, while high-efficiency solar panels generally achieve 18-25% efficiency.
