Financing Available for Renewable Energy Projects of 500 kW to 25 MW

Conergy, a solar photovoltaic service and solution provider, has launched its Conergy Fund I program. The program, which provides financing to large-scale construction projects in the United States, makes the use of and savings from solar power a possibility to businesses.

With an initial target volume of $100 million and backing by Conergy’s main investor, Kawa Capital Management, The Conergy Fund I provides financing for solar power plants and qualified commercial projects with renewable energy capabilities between 500 kilowatts and 25 megawatts of power. The fund streamlines the financing process by managing the financial analysis, credit rating, administration and finance, billing, and collection of power purchase agreements (PPAs) on behalf of the project.

“The Fund is ideal for mid-to-large size organizations such as municipalities, school districts, utility companies, and investment-grade corporations because the savings achieved last for decades,” says Anthony Fotopoulos, CEO of Conergy Americas. “Not only are these entities reducing energy consumption, but the fixed energy prices secured through the PPAs are significantly lower than market prices for conventional grid power, providing additional savings to the end-user.”

Access to competitive financing that can monetize local and federal incentives is a key barrier to the widespread adoption of solar photovolatics (PV) via PPAs – only about 40 percent of commercial buildings or power plants are able to secure this financing. The fund bridges this gap by removing the funding barrier that has historically hampered organizations from installing photovoltaic (PV) systems on their facilities.

Through The Fund, Conergy and its partners also provide project development and engineering, procurement and construction (EPC) services, including engineering, design, and subsequent operations and maintenance management.

Kawa Capital Management acquired Conergy in August 2013 to create a globally unique player in the solar energy industry. Conergy’s expertise in providing complete solar energy solutions and Kawa’s established financial and management strategies were the groundwork for the Conergy Fund I program and will serve as the foundation for future financial solutions in the US electricity market.

“The Conergy Fund I program is the first step in a long relationship with Kawa. We already have five projects in the United States utilizing The Fund and expect to develop and acquire projects in other growth markets in 2014,” says Fotopoulos.

S-5 Announces Metal Plus as New Distributor

S-5!, a manufacturer of ancillary attachment technology for the metal roofing industry, has announced its most recent full-line distributor, Metal Plus LLC.

Metal Plus produces a line of standing-seam brackets designed to simplify temporary staging or scaffolding for metal roofing projects. Because the Metal Plus brackets allow contractors to get to work quickly and safely, they make an excellent platform for installing S-5! products. Pairing these two product lines, roofers, contractors and solar integrators can quickly and cost-effectively attach solar arrays, snow retention systems and other ancillaries to metal roofs without damaging the roof.

Rob Haddock, CEO at S-5!, feels confident the relationship is a good fit for both companies and states: “At S-5! we take innovation, development, thorough testing, and proper market introduction very seriously. We pride ourselves in providing only the best solutions in the metal roofing industry, and I have been impressed with Metal Plus’s commitment to the same.”

According to Mario Lallier, owner of Metal Plus: “We realize that becoming a distributor for S-5! marries two great products, destined to make life for metal roofing installers and contractors much easier. The synergy between metal roofs, S-5! clamps, and Metal Plus brackets equals cost and labor savings upwards of 15 to 25 percent.”

A Solar Installer Explains the Many Ways Roofing Contractors Can Be Involved in Solar Installations

The solar-power industry has changed dramatically in the past five years. Products and manufacturers have come and gone; tax incentives have become less attractive; and requirements for utilities to maintain a certain percentage of their energy portfolio from renewable sources are not enough to help the market in most places. Despite these negatives, unique financing mechanisms and the remarkable decrease in the cost of solar panels keep the industry booming. These ups and downs demonstrate why Matthew Bennett, vice president for design and engineering and founder of Dovetail Solar & Wind, Athens, Ohio, refers to the industry as the “solar coaster”.

Bennett’s business, which was established in 1995, installs solar on residential and commercial buildings. As such, he has worked with a number of roofing contractors over the years and sees synergies between the trades. Roofing asked Bennett how roofing contractors and solar installers can improve their relationship and achieve successful solar installations upon watertight roofs.

Roofing: When must you coordinate with roofing contractors?

Bennett: On almost every commercial roof where roof penetrations are required we’ll have a roofer come in and flash the penetrations and sometimes install a sleeve to get our conduit off the roof and into the building.commercial solar array

The other common reason for coordinating with a roofer is because the roof may be under warranty. Sometimes the warranty is held by the roof manufacturer, so we receive a list of roofers who can do the inspection. Usually there’s an inspection that needs to happen before and after the solar installation. We’re sometimes paying $1,000 to get inspections.

A lot of times we’re not fastening solar panels to flat commercial roofs; we’re installing what’s called a ballasted system where we may need to use an approved pad or put down an additional membrane to protect the roof from the pan that is holding ballast and keeping the array on the roof. Sometimes different roofing manufacturers are picky about what they allow on the roof and different kinds of roofs require different treatment, so it’s important to have a good roofing contractor available.

Roofing: When you hire contractors, what are you looking for?

Bennett: We’re looking for a roofing contractor that does quality work at a fair price because, I’ll be honest, we’ve been overcharged by roofers more than any other subcontractor. We take notes when we work with a roofing contractor: how easy they are to work with, how responsive they are to emails and phone calls, the quality of work and the price. We know roughly what to expect after being in business all these years. If we get a fair quote from a recommended contractor, we’ll often go with them without looking at other bids. We prefer to use a roofer who is familiar with the roof. A good relationship with the customer also is an important consideration.

Roofing: Are there situations in which you defer entirely to the roofing contractor?

Bennett: It’s a little unusual. We just put a system on a slate roof on a million-dollar home. The roof was very steep and we didn’t even want to get on the slate, so we hired the roofer to install the rails and solar panels. We did all the electrical work and procurement. We provided one of our crew leaders to be there the entire time to train the roofing crew and help them because they had no experience with solar. They knew how to get around on a slate roof and mount the solar flashing and they actually installed the whole array. They did it in not much more time than we would’ve done it. We were very impressed with them.

Are You ‘PV Ready’?

Commercial rooftops are an attractive platform for the installation of solar photovoltaic (PV) electricity-producing systems. These low-slope roofs offer an economical and sustainable structural foundation for renewable solar energy. As an example, one of the largest roof-mounted PV systems in North Carolina has been online for several months at the Old Dominion Freight Line Inc. vault logistics facility in Thomasville. Almost 7,700 solar panels completely cover the warehouse’s 160,000-square-foot roof and produce enough power (1.8 megawatts) to offset more than 90 percent of the building’s annual energy costs.

Success stories like Old Dominion’s are becoming increasingly common in the sunny Carolinas. However, it is important to remember a roof’s function is, first and foremost, to protect the building’s contents and people from the elements. In this regard, roofing professionals need to anticipate the potential risks associated with the installation of a roof-mounted PV system (array). This sort of due diligence is particularly important when installing PV systems on existing warranted roofs.

To help in these industry efforts, members of Waltham, Mass.-based SPRI—the trade association that represents sheet membrane and component suppliers to the commercial roofing industry—have developed “PV Ready” roof assemblies and guidelines designed to provide maximum protection for the roof (and maintain its warranty coverage).

In September, SPRI’s technical committee and board of directors also approved and distributed to its members Technical Bulletin 1-13A, “Summary of SPRI Membrane Manufacturer Photovoltaic (PV) Ready Roof Systems and Services”. The bulletin contains general guidelines from SPRI related to “PV Ready” roof assemblies. This article goes into more depth about issues related to PV installations, particularly on existing warranted roofs.

Ask the Right Questions

The installation of a PV system on an existing warranted roof raises many important questions for the roofing professional and building owner. For example, will the roof accommodate the added weight of the PV array? Logistically speaking, before property owners decide on a solar-power system, they will need to determine whether their roofs are sturdy enough to support
the additional loads put on the existing roof structure by the solar array.

An average solar panel and support system typically add a minimum of 3 to 4 pounds per square foot to the existing roof. It is the responsibility of the roofing professional to ensure this additional weight does not exceed the load limits determined by the building’s designer.

From an economic (life-cycle-cost) point of view, it makes sense the service life of the existing roof membrane will come close to matching the projected service life of the PV system. If not, a complex and costly reroofing project may be required long before the solar panels need to be replaced. In general, the underlying roofing system must provide the same minimum investment horizon—generally at least 25 years—to realize the full potential of the rooftop PV system.

Most PV arrays require penetrating the roof membrane. Even non-rack-type systems may include electrical conduits, wiring and other components that may need to be flashed in a professional manner. It is essential the responsibility for this flashing work rests with the roofing contractor.

Inovateus Solar Installs Solar-power System on McElroy Metal’s Manufacturing Facility

South Bend, Ind.-based Inovateus Solar LLC, a worldwide installer of commercial and industrial solar-power systems, has embarked on a rooftop solar array project on Bossier City, La.-based McElroy Metal’s Peachtree City, Ga., manufacturing location. The project is part of the Medium Scale Georgia Power Advanced Solar Initiative Program. Construction on the facility’s roof and a parking lot canopy began Sept. 29. The 500 kW array is scheduled to be commissioned before Christmas.

“It is the largest solar installation for a metal roofing manufacturer,” states Inovateus Solar Project Manager Peter Rienks. “McElroy is really stepping up to the plate to incorporate renewables into their product offering.”

McElroy has 12 manufacturing facilities across the U.S. Through its partnership with Inovateus Solar, McElroy now manufactures ready-to-install solar panels fully integrated into steel-panel systems and offers solar kits with the company’s metal roofs.

McElroy Metal President Ian McElroy says: “We are very excited to be installing a half-megawatt photovoltaic system on our Peachtree City facility. The existing metal roof is over 34 years old and consists of galvanized R panel. We will be retrofitting with our 238T symmetrical standing-seam system, which provides an excellent metal-over-metal reroof solution. And, since we were installing a new roof, we decided to explore adding solar. With the help of our solar partner, Inovateus Solar, we were able to put together a plan that made financial sense.”

SPRI Distributes ‘PV Ready’ Technical Bulletin

Waltham, Mass.-based SPRI’s Technical Committee and board of directors have approved and distributed to the organization’s members Technical Bulletin 1-13A, “Summary of SPRI Membrane Manufacturer Photovoltaic (PV) Ready Roof Systems and Services”. The bulletin contains general guidelines from SPRI related to “PV Ready” roof assemblies and services designed to provide maximum protection for the roof (and maintain its warranty coverage). SPRI represents sheet membrane and component suppliers to the commercial roofing industry.

“Commercial rooftops are a convenient platform for installing solar photovoltaic systems,” says SPRI Technical Director Mike Ennis. “However, it’s important to remember that the roof’s primary function is to protect the building’s contents and its people from the elements.”

Technical Bulletin 1-13 raises important considerations for the building owner, such as the added weight of a PV array and the impact of wind and fire approvals. The bulletin also lists potential PV system-specific requirements from manufacturers to maintain existing warranties; project documentation forms frequently required to install the PV system over an existing warranted roof; and general issues and additional services offered by manufacturers, such as single-source warranties for the roof system and solar integration.

SPRI gathered the information included in Technical Bulletin 1-13 from a survey of information available on websites and literature of SPRI member membrane manufacturers. As such, the bulletin serves as a summary of the PV-ready products, requirements and services currently offered by SPRI members and is available for distribution to customers.

“Each SPRI member may have its own PV ready program, and no SPRI member may necessarily be considered to have all program elements,” Ennis adds. “The building owner should always consult the manufacturer of the roof system specified for the new construction or reroofing project prior to the installation of a PV system on a warranted roof.”

In addition, Ennis writes about PV Ready rooftop considerations in “Tech Point”.
