As solar roofing emerges as an evolving sub sector of the industry there are a lot of misconceptions as well as flaws in many existing business models. For example if you are a residential home owner that has been looking for information about Solar Roofing / Solar Systems installed on the roof, we have yet to see a model that points out the most simple fact that when you have an asphalt composition shingle roof (4 out of 5 homes by statistic) which is already starting off with a net building envelope efficiency loss of, – 15% to -20%, that if someone says we can reduce your energy bill by installing a Solar System that is Roof Mounted there is a lot more to it than many people make it appear.

For example, if you live in a house built Prior to 2008 when Houston Adopted their Energy Code, then most likely there is more to making things work than just installing a Solar Roofing System. Consider this, when you counter: (the net sustainability loss of 15% to 20%) with your average Roof Mounted Solar Array that has a average net gain of up to +20% in the end you essentially wind up with a wash / or a true net gain of 0; assuming you have a Asphalt Shingle Roof and beneath it still has the original R 18 Insulation, and we have not even examined if your ventilation is balanced. Sure if installed by the correct professionals there is a 30% tax credit / that is correct 30% of the total cost for the system to be installed; however when thinking about Solar you have to think about all the pieces of the puzzle, (The Roof Type / if Roof Mounted), (The R Value Beneath the Roof), the NFA / Net free area of balanced ventilation. Then start the process by assuring that everything is where / or as close as it needs to be.
If you take the time to consider those things, not just what some Sales Person is telling you, by accommodating and taking into consideration every variable possible that affects the building envelopes efficiency, and making whatever corrections need to be made to maximize efficiency then you will know that your gains and efficiency can be maximized. While the upfront cost will be higher the long term Return on Investment will be offset greatly during the course of the Life Cycle of the Solar Roofing System.
If you are wondering, “What is a Photo Voltaic System?” We have included a link to Wikipedia as well as one more to: Roofpedia, Wikipedia has many articles explaining what it is, as well as how it works, and Roofpedia has a article with a Specific Focal Point on Solar Roofing, understanding how these systems work we hope will help you better understand the rest of this article on Solar Roofing Information, go to:
Or: http://roofpedia.com/solar-roof-shingles/ a up and coming resource for Roofing Information
The wikiroof.blogspot is a great article that provides great information about Solar as well as Nano Technology, by Mr. Ron Solomon, State of Florida Sustainability Judge, Director of The Roof Consultants Alliance, as well as a advocate in proper procurement methods and a proponent of, “Proprietary Specifications”, who has saved the Tax Payers a lot of money as well as helped to promote Sustainability.
Moving on, is installing Solar Modules over Asphalt Shingled systems wrong? No, however unless the potential buyer understands what net gain is, as well as net loss from the Asphalt Based Roofing System the Solar Array is installed on top of it then they may not be maximizing the gains or the return on the investment, commonly referred to as, “ROI” (Retrun on Investment), unless part of that equation or system includes increased attic Insulation to offset the Net Loss from the Asphalt based underlying Roof System, unless it is verified that the Attic already has a R30 value, then there are issues that we recommend working out . There is also the possibility that down the Road Companies that Jumped on the Solar Band Wagon, without complete understanding of building envelope efficiency promoted more than what was actually provided could very easily cross the wrong person and potentially that person decides to seek resolution via: DTPA Litigation, (Deceptive Trade Practices Act), particularly if they knocked on your door.
One other potential flaw is that the majority of the companies installing Roof Mounted Solar Systems are Electricians and not roofers, and may not look at the fact that for the numbers to work you need a roof assembly with a 20 to 25 year life cycle, and that if a Solar System is installed on a Roof System with less than a 20 to 25 year life cycle, at some time the structure will require re roofing, creating additional cost down the road when everything may need to be re installed.
Recently the website, “Electric Energy Online .Com” published their release at:
Going right to basis of their post, City of Houston Increases Renewable Energy Purchase and the summation of the Article; however it offered very little design information for consideration.
The Roof Consultants Institute RCI explains the concept of why the cost to upgrade a Commercial Roof System to a 30 year System, in their post Called, “Go Big” that can be viewed at:
By following concept and having a Commercial Roof that can be covered by a 30 Year NDL (No dollar limit) total system warranty is in the end the best fit for Commercial Real Estate Investors, as well as System Designers to design a roof system that first is ECO friendly, second does not cause a loss in building envelope efficiency as they illustrated in easy to understand context why spending extra up front creates to best possible scenario for long term performance of the both the Roof and the Photo Voltaic Systems, or as we have been referring, Solar Roofing.
Please read there article on, “Why Supersize my Roof”, as it clearly explains the best options for Commercial Real Estate Investors, as well as Local Government Groups how to best capitalize on having the best roof to go with the Photo Voltaic Roof Mounted System.
The PACE Program (Property Assessed Clean Energy) Program contains a lot of great resources for both
Commercial and Residential Owners looking to acclimate to clean Renewable Solar Energy, they have many great resources to help properly explain everything from Legislative Acts, to incentives, to a incredible Overview of Photo Voltaic integration as well as many incentives that are available. Go to the link below to find out more about this program:
Anchor Roofing is all for promoting Solar Roofing in Houston and is endeavoring to implement the best business model possible that explains all the pro’s and con’s that many people looking to integrate may not fully understand. With a focal point on what to do to see the highest true gain, with a starting focal point of what is the best design for the roof assembly as well as the possible Photo Voltaic System that can go on top of first, then second what system is the best possible scenario to maximize your gains, with a myriad of options from established Solar Manufacturer’s, not just one option, and see the full intended life cycle as well as understanding that different families have different Energy Consumption, and while a Large System may be ideal for some families or businesses, and you may be able to purchase a system that can literally negate your need for a outside power supply, you most likely may not be able to sell back whatever extra energy you produce back to Renewable Energy Providers for what the end user pays per Kilo Watt Hour.
The Carbon War Room is another excellent site that offers information for, Citizens, Entrepreneurs, Investors, and Manufacturer’s as well giving a perspective on how Photo Voltaic System reduce the Carbon Foot Print, and greatly help the environment. Their site is full of incredible resources and can be viewed at:
Understanding that the more the consumer knows, the better decisions that they can make, is our primary goal. Solar is here; however as Sir Winston Churchill said, “A goal without a plan is merely a wish”.
