BACKGROUND

History of Solar Technology

Rising energy costs have driven the demand for alternative and renewable energy

sources. In response to these rising energy costs and environmental concerns,

alternative energy sources are in high demand. Solar, water, geothermal and wind

technologies have been developed with the goal of reducing energy costs without

further risking the status of the environment.

Photovoltaics (PV) is one solar solution. Hydro-electricity has long been used to harness

the energy of fast-flowing water to generate energy. Geothermal energy has been usedto heat buildings and to produce electricity, while wind turbines have generated a

growing amount of electrical energy in recent years.


11/82

BACKGROUND

Photovoltaics

Solar roofing just makes sense.

On-site solar technology can:

Reduce utility costs

Reduce dependency on fossil fuels

Help reduce greenhouse gasemissions and other ozone depleting

compounds


12/82

BACKGROUND

History of Solar Technology

Photovoltaics (PV) is a solar power technology that uses cells to capture and convert light

energy from the sun into electricity; it is the fastest growing energy technology.

Simply speaking, photons from the sun excite the electrons, bumping them into a higher

state of energy, producing electricity inside the PV cell.

The general trend in photovoltaic technology production has seen substantial growth

nearly doubling every two years since 2002.

PV has seen such success because it is less dependant on local weather patterns than

other renewable sources.

BACKGROUND

Photovoltaics

Putting solar panels on a roof is a logical decision. The roof is constantly exposed to

sunlight where it can readily be absorbed. The building will absorb rays from the sun and

use the energy to create electricity.

Buildings use a tremendous amount of energy. In most cities around the world, the roofs

of buildings are exposed to sunlight forthe majority of the day,

everyday. It is sensible

to have the electricity

source located near

the energy consumption

location rather than autility company across

town.


15/82

BACKGROUND

PV System Obstacles

OK, weve put a solar system on the roof. But what did it take to get it done? As

architects started to incorporate solar technology into their specs, they experienced at

least four common problems. First generation technology taught us that each project

required a custom design.

Customization led to high costs. Because each design was unique, there were oftenperformance and warranty issues. Each system was attached to the roof differently

because the design was not building-integrated. There was no way of knowing if the

hardware involved in attaching the solar panels would affect the integrity and

performance of the roof because each roofing material was different as was each design.


16/82

BACKGROUND

PV System Obstacles

We learned that first-generation solar roofs:

Had high costs

Were not building integrated

Had performance issues

Had warranty issues

FIRST GENERATION SOLAR APPLICATIONS


17/82

BACKGROUND

PV System Obstacles

One of the biggest obstacles to implementing earlier systems was the lack of any standardized

method for designing, specifying or installing a solar energy system. The building changed, so too

did the roof, and ultimately the solar panels wiring and mounting because there was no pre-

designed system. Traditional hard-panel systems limited their use to static, stationary structures.

Each system required custom designs and specifications, preventing easy adoption of the

technology. Each system would have to consider the effect of wind loads, fire codes, electricity

codes and how the component parts would work together to capture energy. Each project required

changes to the specs for the panels, how they would be wired, how they would be attached to the

roof, how they would perform, where they should be placed, and so on.

Because of these variables, budget and ROI estimates were often inaccurate. As you can see on the

following example, traditional solar technology often required ten years before the building ownersand investors saw a return on their investment. This chart is an illustration to demonstrate the

length of time commonly associated with ROI for traditional solar technology.

19/82

BACKGROUND

PV System Performance

First generation technology was most effective in high sunlight and the solar cells were

fragile. If one cell in a panel was damaged, up to half of the panel would lose

functionality. Damage often resulted from impact by hail, or other extreme weather

conditions. The industry recognized that for solar technology to be adopted, normal

abuse must not damage the solar cells.


20/82

BACKGROUND

Standards and Warranty

There was no standard system, no standard installation, no standard products, no

standard warranty with the first-generation, non-BIPV solar panels. Specialty

contractors who installed the PV components would offer a warranty on the PV

system, but that varied from contractor to contractor.

Typically the warranty of the roofing manufacturer would become void if

penetrations to the roofs surface were made for installation. The warranty may alsohave become void if the panels were attached to the roof without the review and

testing of the roofing manufacturer.

The industry recognized that for solar technology to be adopted, the addition of a

solar system could not negate the roofing system warranty.


21/82

BACKGROUND

The final obstacle preventing those requirements from being introduced was that this

order was left to all of the roofing or solar technology manufacturers to solve. The

investment required for one manufacturer to develop, test, and produce a product to

solve the industrys problem was too large.

22/82

BACKGROUND

Development Feasibility

Architects and building owners want to use solar technology and they want to do so

with greater ease and more assurance that the product will perform in a reasonable

amount of time. Architects challenged the roofing and solar product manufacturers to

develop a solar system that was building integrated, had a reasonable return on

investment and could provide an inclusive warranty from one manufacturer for BIPV

system.

To do this, you needed a pre-designed, building-integrated system with CAD drawings,

specs for electrical and mechanical components, a solution to eliminate mounting panels

or additional structural support, and accurate return on investment estimates of 10 years

or less, for large and smaller economical systems that would be sustainable, with a

guarantee that the whole system would work well into the future, and for all of this to be

ready for competitive bidding by traditional sub-contractors.

BACKGROUND

The Solution

The standing seam roofing industry and a leader in solar technology partnered in 2006 to

develop a new building integrated photovoltaic (BIPV) solar system that met all of the

requirements that the architectural community requested.

A complete, standardized, and affordable BIPV system was released in 2007 and available

to the commercial building industry, making the specification of a solar energy systemeasier than ever.

This BIPV system is available from the standing seam roofing industry only.

TECHNOLOGY TODAY

One of the most important characteristics of integrating alternative energy into buildings

is the effectiveness with which it can replace or improve upon pre-existing or traditional

energy sources. New BIPV laminates deliver the kind of solar roofing system that has

been asked for: pre-designed and system integrated, making solar energy attainable for

projects of all sizes.


29/82

BIPV COMPONENTS

Lets begin by walking through thecomponents of the new BIPV technology to

understand how they differ from traditional

crystalline systems. Well examine in detail

the cells, the laminate, and the adhesive of

BIPV laminates.

Anatomy of a PV laminate panel:

Cells

Laminate/plastic

Adhesive


30/82

BIPV MATERIAL TECHNOLOGY

PV laminate cells are applied to a 5-mil stainless steel substrate. This light material allows

them to be flexible, easily integrated and reduces unneeded weight and stress on the

roof.

The new BIPV laminate technology allows cells to collect three spectrums of light red,

yellow/green, and blue. This means that they produce more total energy per rated watt

because of the triple-junction technology.


31/82


In addition to increasing the amount of light that can be captured, new BIPV laminates

are wired differently, to help ensure consistent energy output. BIPV laminates cells have

bypass diodes across each cell, meaning if one cell is damaged, only that cell stops

working.


32/82


Flexible plastic allows the panel to bend and be curved, fitting to non-standard roof

shapes. It can also be walked on without damage. Laminate panels are 15.5 inches wide

and fit perfectly into standing seam roofing panels that are 16 inches wide or more.

In the photo the laminates take the shape of the standing seam roof. Your designs and

ability to incorporate alternative, renewable solar energy into any of your projects is no

longer limited to flat roofs.


33/82

BIPV ADHESIVE BOND

The adhesive that bonds the laminate panels to the roofing substrate has several

benefits:

Eliminates the need for installation hardware and structural supports.

Reduces likelihood of damage to the roof.

No roof penetrations required.

Reduces cost of installation.

Adhesive bonds tested on several substrates, in different climates, and under severe

weather conditions.

34/82

PRE-DESIGNED ELECTRICAL COMPONENTS

Cable trays are designed to match the roofing color; they protect and hide the

electrical wiring components. The Underwriters Laboratory (UL) requires a wire

management system to protect the wires from exposure to the elements. The

combiner boxes house the wires from different locations, combining them into one

wire. The AC and DC disconnects are required by code, and act as on/off switches. The

inverter converts electricity from its products type (DC) into usable (AC) power. The

transformer maintains the proper voltage for the inverter.


35/82

PRE-DESIGNED ELECTRICAL COMPONENTS

An optional data acquisition system will tell you how much energy your system is

producing in terms of common, daily items this will help you put your savings and

consumption into perspective.

All electrical components are pre-designed.

INSTALLATION ON ROOFING PANELS

BIPV laminates are easily installed onto the roofing panels by one of the following

means:

At the manufacturers facility in a controlled environment, then shipped to the

project location.

Laminating panels on site during construction.

Either installation method does not compromise the integrity of the roof, nor does it

require specialty contractors, additional hardware, drilling, or structural support

mounting.

Cost of installation is drastically reduced utilizing either one of these installation

methods.


37/82

BIPV AESTHETICS

Building-integrated photovoltaics represent a change in the aesthetics of the solar

energy system. Because the PV laminates fit conveniently between the ridges of standing

seam panels, they do not block any views, cast any shadows or cause glare in your line of

sight.

BENEFITS OF BIPV

Energy Efficiency

The PV laminates used in the BIPV system offer superior performance in low light and

overcast conditions. These advantages allow the BIPV system to be installed in a wide

variety of locations and climates.

Regardless of location, electricity generated by the system is returned to the electrical

grid, with the building being credited for the electricity it has produced. This process is

known as net metering.

BENEFITS OF BIPV

Economic Benefits

BIPVs can return the owners investment in under 10 years in some states. Return on

investment is based upon the performance of the system and federal, state and local

incentives associated with using solar technology on new or existing buildings.


42/82

BENEFITS OF BIPV

Environmental Benefits

A building equipped with BIPV laminates produces its own electricity and reduces its

reliance on an environmentally-unfriendly coal power plant. The more solar powered

buildings contributing to an electrical grid, the less energy a power plant needs to

consume. Consequently, the power plant emits fewer pollutants into the air.

Taking this idea a step farther, requiring less energy from power plants results in adecreased dependency on utilities and the oil used to power them. Each of these

advantages benefit the environment by reducing carbon emissions.

Overall, BIPVs reduce:

Greenhouse gas emissions

Dependency on utilities

Dependency on oil

Carbon footprint


43/82

SPECIFY A STANDARD SYSTEM

The new BIPV system was designed with architects in mind. By standardizing eight

system sizes, including specifications, panel and electrical drawings, and engineering

data, the onsite renewable energy BIPV system allows you and the manufacturer to

streamline the solar energy specification process. You dont have to reinvent the wheel

with each new project. Everything has already been done for you. Eight system sizes are

available from 3kWs to +240kWs to fit any project.


44/82

SPECIFY A STANDARD SYSTEM

Each BIPV system size includes pre-written specifications. All electrical and panel

drawings are designed and formatted for each available BIPV system size.

For the standing seam product, your SSMR (standing seam metal roof) manufacturer can

provide the specifications for section 07400 (MasterFormat 95)/07 41 13 (MasterFormat

04). Electrical specifications can be provided to be included in section 16130 (MF

95)/26 05 33 (MF 04).

CAD Drawings and Pre-written Specifications:

You include the details/specs for the standing seam roof in section 07400/07 41 13 of

your specifications.

An electrical engineer will include electrical schematics in their electrical drawings

and will include the specifications in section 16130/26 05 33.


45/82

SYSTEM SIZE

There is a BIPV system for projects of any size for both residential and commercial

projects. For residential applications, a 3 kW system is available. For larger, commercial

or industrial applications, the larger system sizes provide you with several options and

varying energy output.

Available sizes are: 3kW, 5kW, 10kW, 15kW, 30kW, 60kW, 120kW, 240kW.

Custom system sizes available upon request.

Analysis and ROI

The Architect can request:

A customized ROI report for their project before construction begins. Using a state-of-

the-art ROI calculator, the architect will receive within five days a report detailing all

aspects of a projects potential BIPV system. This data includes expected power

production and ROI payback. You can present this payback to the building owner to

support your bid for a project.

Note: Only SSMR manufacturers utilizing a renewable energy system analysis program

have an accurate ROI calculator available.

government or utility company incentives available for incorporating alternative or

renewable energy technology into your project. Perhaps most importantly, the calculator

provides you with an accurate return on investment payback.

ROI Calculator Reports provide a detailed analysis of the following:

The projects expected energy output in AC kWh.

49/82

ENERGY SYSTEM

Analysis and ROI

The data on the expected energy output is used to create a complete and thorough

financial analysis that includes 25-year cash flow information. The financial analysis

reveals the payback time in years and the internal rate of return on the initial

investment. Numerous federal and state financial incentives for using alternative energy

sources are becoming increasingly important for accurate ROI calculations. These

favorable incentives, combined with low installation cost and high efficiency can, in somecases, decrease ROI to between four and six years.

Decrease ROI to 4-6 years in some areas where:

Cost of electricity is high or increasing

Incentives & rebates exist Low installation cost of pre-designed systems

High efficiency of PV laminates

Ideal roof slope and building orientation

ROI CASE STUDY

The ROI estimate on this graph is for a medium sized commercial project in Alliance,

Ohio. The total roof area is 66,000 square feet; a 54kW system was installed on 10,080square feet of the roof facing towards the south. The building owners will begin to see a

return in the second year.

This system will produce approximately 1,546,741 kWh of energy over a 25 year period,

saving $338,441 in electricity costs alone. CO2 emissions are calculated to be reduced by102,292 pounds annually.

ROI & INCENTIVES DATABASE

As we just mentioned, federal and local incentives for alternative and renewable energy

help to lower the ROI time. The problem is that incentives all have differentrequirements and to determine which credits your project qualifies for may be time

consuming. The energy system analysis program ROI calculator references a database

containing all state and federal financial incentives, renewable energy credits and utility

company credits. Included in the report is a list of incentives for which your project

qualifies. These incentives are then factored in to your final ROI timeline. The database is

kept up-to-date.

EMISSIONS REPORT

Furthermore, the report details the amount of pollutants avoided by generating

electricity with the BIPV system. For example, a 54 kW system in Ohio would reduce CO2emissions by over 69,000 lbs.

The calculator also generates positive environmental aspects of installation, including

reductions in greenhouse gasses like:

CO2 emissions SO2

NOX gasses

VOCs

PM10

ATMOSPHERIC POLLUTANTS


54/82


This chart shows how many pounds of atmospheric pollutants can be saved by one building with a

54 kW BIPV solar laminate system. This building was specified with a total roof area of 66,000square feet, of which 12,080 square feet were facing in a general southern direction (either east or

west). These numbers are specific to climate data, utility rates and energy output in Alliance, Ohio.

As you can see in the first row, Carbon emissions could be drastically reduced each year regardless

of the type of fuel used to create the electricity to run the buildings systems. While Carbon is not a

toxic gas, it is a strong heat-retaining greenhouse gas that has been linked to global climate change.

This chart puts energy savings into

perspective by showing the equivalent

number of pine trees saved from

harvesting. A second comparison shows

that the same emission would result if

65,154 miles were driven by SUVs.



55/82


Oxides of nitrogen are some of the main causes of smog and are also associated with

acid rain. These gasses irritate the airways of the lungs and can worsen heart and lungconditions. Solar energy can reduce nitrogen-based oxides by reducing the amount of

combustion reactions required to produce electricity.

Sulfur dioxide is associated with visual pollution of the atmosphere, as haze, causing the

sky to appear yellow. It is also associated with acid rain. Reducing the amount of sulfurdioxide produced can help reduce haze and acid rain.

Solar energy also reduces by-product production of particulate matter and volatile

organic compounds (VOCs), which can cause various health conditions.

ENVIRONMENTAL BENEFITS


56/82

ENVIRONMENTAL BENEFITS

Analysis

An extra benefit to the ROI calculator will put into perspective the environmental

benefits of the BIPV system. The ROI calculator will tell you the equivalent number of

trees planted or number of SUV miles not driven.

This will help you quantify the savings in everyday terms, leveling the playing field foreveryone involved in the specification, selection, installation, and end use of the

standing seam BIPV solar system.

XLets continue with the example of the medium-

sized commercial building in Ohio. That system

would save the equivalent of 7,307 pine trees

from being harvested or 65,154 SUV miles being

driven.

Standing seam metal roofs can impact the following LEED credits indirectly. The use of

this roofing cannot earn these points on its own, but they can contribute to the point ifproper materials and methods are used.

SS Credit 7.2 - The Heat Island Effect Roof credit encourages use of roofing

material compliant SRI values. For a low slope roof, SRI must be greater than or equal

to 78. For a steep slope roof, SRI must be 29 or greater for 75% of the roof. Note: square footage of PV panels is subtracted from the total calculated roof area*

local materials.

MR Credit 1.1 - If you retrofit an existing metal roof, it can contribute to building

reuse. BIPVs can be installed on an existing metal roof.

MR Credit 2 - When the panels are being installed,

scraps can be diverted from the landfill as they are recyclable.

MR Credit 4 A metal roof can be manufactured using recycled content. Percentages

and sources vary and should be specified with the manufacturer.

The same holds true for core and shell, but the minimum improvement is 8% for one

point, and increases from there up to 44% improvement in energy performance.

The estimated energy output provided in the ROI estimate will help you establish the

percentage increase in energy performance. You can use this tool to compare how

different system sizes will increase performance of just the roofing system. While the

BIPV system may significantly improve performance, it is important to remember thatthis option requires all building systems be factored into energy performance estimates.

OPTIONS TWO AND THREE are prescriptive compliance path methods, based on the

energy and performance guides. These methods are equal to 1 point for option two and

1 3 points for option three if achieved. BIPV roofing systems can contribute to the

buildings performance by improving performance over the baseline, therebycontributing points towards credits. BIPV roofing can be a low cost contributor to the

overall energy-efficiency of the building.

HOW TO SPECIFY A BIPV SYSTEM


71/82


When youre ready to consider BIPV for a project, youre next step is to request an ROI

report based on specifics of your project such as: location, building orientation, roofslope, size and area of clean roof, the utility company serving the project, current or

anticipated cost per AC kWh, building type and owner type.

Once youve reviewed your custom ROI report, you will be able to determine the most

beneficial system size for your project. Select the system size and request CAD and BIPVdrawings from your standing seam manufacturer to incorporate into 07400/07 41 13

bidding documents.



72/82


Review the roof location, layout plan and cable tray location with your standing seam

manufacturer. Request electrical CAD drawings and specs from the standing seammanufacturer to review with your electrical engineer, who will incorporate them into the

16130/26 05 33 specifications. Finally, decide if the BIPV system is to be bid as an

alternate or included in the base bid.

Your ROI report will help you decide to proceed or not, and if so, help you select the bestsystem size for your project. You can base your decision on information in the ROI

report, such as cash flow, energy savings, payback and environmental benefits.

CONTRACTING

When the building owner or investors have approved the project your next step is to

contract the project for installation. The general contractor will receive competitive bidsfrom roofing and electrical subcontractors. You will review the bids with the owner and

general contractor before the general contractor awards the contract to a subcontractor.

The contract will include installation of BIPV panels, electrical parts, wiring and

commissioning by installers and electrical subcontractors.

CONTRACTING

You will review shop drawings from the standing seam manufacturer to confirm portions

of BIPV, location of BIPV and cable trays. With the approved shop drawings, the standingseam manufacturer will order and integrate the PV into the standing seam roof system.

The electrical engineer will review the electrical subcontractors drawings for compliance

with specs and confirm the location of disconnects, inverter and other components.

With the approval of the building owner or investors, youre now ready to contract theproject and have the BIPV system installed by traditional roofing and electrical sub

contractors.

COURE SUMMARY

REVIEW


79/82

REVIEW

BIPV systems will raise awareness of solar energys potential as an alternative energy

source. Architects and members of the metal roofing industry recognize theexcellent opportunity to lead the way to a greener building future through solar

energy.

When considering solar roofing, utilize an onsite renewable energy system analysis

program to ensure peace of mind that the BIPV system will be installed properly and

ensure high performance.

Just 10 years ago, bulky and fragile polycrystalline panels limited the U.S.

architectural community in solar energy.

Now, architects have access to a reliable and affordable BIPV photovoltaic system.

COURSE SUMMARY
