Creative financing completes 530-kW solar + storage install at San Diego retirement community

Paradise Village Retirement solar

Generations LLC added an expansive 527.8 kW photovoltaic (PV) solar + storage system on its resort style independent, assisted living and memory care community, Paradise Village, in San Diego’s South Bay. Combining solar with a behind the meter energy storage system, the energy enhancing project will produce approximately 1 million kWh of electricity per year, approximately 40 percent of the campus’ annual electricity usage. In addition, an estimated cost savings of $250,000 in both regular and peak demand usage will be provided from the hybrid solar and low-cost battery storage system.

Financing details

Generations LLC and NW Photon Energy (NWPE), both of Portland, Ore., partnered on the pro-ject which has been in development for three years. According to Kirk Cameron, President of NW Photon Energy, this project became viable as a result of four key factors.

1. The foremost was a healthy ROI with a payback of less than 5 years.
2. Helping Paradise Village gain control of its energy expenses and eliminate rising utility in-creases was the second factor.
3. Paradise Village’s qualification for a CPUC Self-Generation Incentive Program (SGIP) rebate covered approximately 5 percent of the total project cost and
4. The final factor was Generation’s 10-year refinance of a previous $82 million construction loan through Fannie Mae’s Green Rewards program – the first Green Rewards loan backed by a sen-ior housing property. This refinance provided exceptional terms and a reduced interest rate which contributed to the aggressive ROI.

According to Chip Gabriel, President of Development for Generations LLC, the business case for solar was clear to them from both a financial and environmental sense.

“With a large percentage of a residential housing community’s operating expenses originating from its energy usage, a sustainable approach to property management is crucial for the long term,” says Gabriel. “Adding solar was not only a financial decision but also one framed by the environmental impact that taking care of more than 400 residents creates.”

Generation’s commitment to solar is a continued example of their foresight and approach to property management. They have identified solar as a means to leverage underutilized roof space to improve operating efficiencies for their buildings.

The next phase in Generations’ energy management plan involves identifying additional solar project opportunities. The company recently contracted a third solar system to be installed by NW Photon Energy at its Linfield Village senior living community in Temecula, California.

Ask a Distributor: We ask distributors for their purchasing advice, products to watch in 2018

solar distributors

Solar is now the No. 1 new source of capacity being added to the grid, according to the U.S. Energy Information Administration, and solar installer is the fastest growing job in the country according to the Bureau of Labor Statistics. And what’s the reason for the rise of this new era? The impending doom of the ice caps melting? Hardly. The advancements in technology? Getting warmer.

Really, things just got cheaper.

This is to say that purchasing plays a large, perhaps outsized, role in the value proposition of the industry and your business. Given that reality, we wanted to kick off the year by polling a handful of solar distributors for their purchasing advice.

You’ll be hearing from:

purchasing

Here’s the No. 1 way to avoid purchasing problems

What are the common problems distributors see when it comes to purchasing systems to install? There are a few quick, solvable issues — stuff like reviewing the details of an order before signing off on it or avoiding last minute purchases.

“Plan ahead and inspect shipments to avoid/mitigate mix ups and ensure fast and timely solutions when needed,” McShea says. “Waiting three weeks until install to say something is missing and you need it now is not effective.”

But all of that feeds into the advice that resonated with us the most: Seeing the distributor relationship as a two-way street that adds value to your business. According to the distributors we talked to, the more often you communicate, the more the distributor knows about your business, the easier it is for them to help.

“Valuing price over loyalty and the quality of the relationship with a distributor, I think, is a mistake,” Schoder from Civic notes.

A simple step up in communication will not only solve a bunch of issues but could create additional value for your business.

“Good communication and transparency are always the best remedies for doing good business and mitigating potential errors,” Dufrenne says. “Everyone is busy and going to make mistakes, including distributors and shipping companies. When all parties pay attention to detail and plan accordingly, deliveries and installations seem to go more smoothly.”

And it’s not just an exercise in mistake avoidance. Keeping everyone on the same page, forecast-wise, can only make the ordering process smoother for everyone.

“At least one call a week to plan upcoming jobs would help avoid supply chain issues,” Kyler says. This ensures all orders and forecasting align with expectations.

There’s also the training aspect. “Manufacturers are constantly offering training, quite often through their distributors,” Bailey notes. “Yet we still see many installers deal with headaches for hours which they could have learned to avoid by going through some quick training on the product features and installation.”

Think about kits

Ordering from multiple suppliers for a given residential job can leave more room for error, such as damage during shipping, incorrect parts arriving or a delayed delivery, all of which lengthens install time and increases costs.

“The best solution I’ve seen yet for lowering soft costs is to have one to two standardized kits which the sales team and installation crew are both very familiar with,” says Leone with Civic. “This mitigates both sales and labor costs. We recommend having multiple kits to protect against upstream challenges such as availability.”

“Ordering from one supplier and having the experts kit the equipment per job before shipping to the jobsite or warehouse can reduce most mistakes that cause delays and additional labor/mobilization costs,” Dufrenne says.

Sticking with brands also avoids the hassle of resubmitting permits with different equipment types or brands.

4 soft cost reduction tips

Schoder: “Utilizing online software programs like Helioscope and Energy Toolbase to drastically reduce the amount of time and effort that goes into a respectable customer proposal.”

Bailey: “Smaller installers like to use microinverters for [lowering soft costs]. In many cases they don’t have the in-house expertise to properly design a string inverter system which can maximize production. Microinverters are flexible, and the installers can design in the field by adding modules as they see fit.”

Dufrenne: “Good operations management [from lead generation to final completion]. Use software, like ENACT.”

Kyler: “Installers should keep at least one administrator dedicated to handling all incoming and outgoing paperwork such as permits, SREC registrations and contracts. This would help reduce soft costs and avoid any confusion or dilemmas later on.”

Truck these rolls

For starters, it helps to have a mini-inventory of small accessories (L-feet, clamps, wire), but stocking extra parts for the rest of the system is always a good idea.

“A common purchasing mistake I see installers make is purchasing just enough for their project instead of calculating for inevitable adjustments when they get on the roof,” Kyler says. “Mostly when it comes to racking, I recommend keeping spare parts in each truck.”
Dufrenne laid it out like this: “Not ordering extra parts for racking and attachments ends up costing much more than you’d think, once you have to roll another truck and pay for overnight shipping charges for parts that are usually less than $10.”

When it comes to the inverter (and we will get into this more on page 28) MLPE or string inverters could each offer a route to reduced truck rolls, if handled correctly. But for now, we just note what Kyler recommends: “Select products that allow remote updates or choose manufacturers that provide service programs.”

“Carry spare parts and get your system up and communicating with your gateway and online account before leaving the site,” Bailey says. “Installers who use gateways can track performance as soon as the system lights up. They can coordinate with technical support and determine within a few minutes that all modules and inverters are performing to spec.”

On the scene: New solar installation products we saw at the California Solar Power Expo

We attended the California Solar Expo in San Diego last week. Here’s a rundown of some of the notable new solar products we spotted around the trade show floor.

S5 standing seam

S-5! is known for its rigorous testing and compliance standards for mounting solar on standing seam metal roofs. Its latest update on the module here (which you probably can’t see) is a better wire management solution than the disc they had been using, after customer feedback indicated it wasn’t wide enough for every application. The update here completely addresses that concern.

Coming soon, you can look out for a solar installation calculator on the S-5! site.

Pegasus

Pegasus Solar is introducing a new tile replacement solution that they say will remove the need for cutting tile while still fitting a wide variety of tile sizes. Key to the design is the attachment sitting on the ridge of the replacement instead of the valley, which keeps it clearer from water that would be funneling through the valley.

Solar connections

Solar Connections is promoting its Solar Connection Kit. Tested to UL 2703, the kit’s cable management disc allows for cables to be top loaded and sit securely. Push-Lock Technology secures the disc to the standing seam base clamp without extra nuts and bolts. Installation is made easy with Silver Bullet set screws that have a rounded bullet tip to maximize strength without digging in and damaging paint or piercing the seam.

CED Greentech

More to come on this, because it isn’t ready yet, but be on the lookout for a new website from CED Greentech.

Snapnrack mounting

SnapNrack is all about aesthetics. Well, they do more than that, but a lot of their latest products do give a sleeker look to a rooftop array while still being functional. The look, specifically is the black skirt with no end cap required.

solar roof hooks

Solarroofhook, known for its direct attach and tile hook solutions, has an updated flashing product. Unlike its previous solution that could bend, this one is stiff, which is something its customers were asking for.

APsystems

APSystems is coming out with a trunk cable version of its microinverters for those who couldn’t get into the daisy chain installation.

Energy toolbase

Energy Toolbase packed the demo stage with attendees who wanted to hear more about its new energy storage software. Energy Toolbase might be the most robust tool out there for behind the meter data and PV system modeling and proposal generation, and its new energy storage component is going to be just as robust. We will have more coverage on this posted soon.

Unirac

Unirac was promoting the shorter rows and greater energy density its rooftop mounting solution makes possible. Oh, and the company recently bumped up its warranty to 25 years.
