Solar Self-Storage Design: Size, Location, Placement and Aesthetics of a Solar-Panel Array

Fortunately, there are three basic types of mounting categories for solar panels: direct attach, ballasted and ground mount. Within each one of these categories, there are many system-specific products.

A large residential installation in Santa Barbara, Calif., features a “top-of-pole” mounting system. Solar panels do not always need to be mounted onto roofs to be effective.

Direct-attach racking systems are designed to mechanically fasten directly to your building’s roof structure. Most racking companies will offer a variety of different mounting brackets, each designed for a different type of roofing system. They’re all designed to provide proper support to the racking while minimizing the impact on the roof.

Ballasted systems use weight or “ballast” to keep the panels in place. This is so you limit or eliminate any roof penetrations to maintain the integrity of the roof.

Ground-mount systems come in many different styles but are basically all doing the same thing: mounting your panels on the ground.

Make It Work

So you’ve figured out what size system you need, and you have a good idea of where you want to put it and how you’ll mount it, but do you even know if your building can handle the installation? This, again, will be based on your individual self-storage facility. For the most part, solar will not place a great strain on your building, so the addition of a solar array should not be difficult for it to handle.

There are, however, two issues that can be a challenge: the weight of the system and the wind load. Unless there's something unique about a facility (i.e., extreme age, unusual construction, etc.), it can usually handle the weight of a solar array because it weighs only a few pounds per square foot. More times than not, the biggest concern will be the wind load. This will require more engineering if you’re in a location with high instances of heavy wind. However, most solar panels and racking systems are designed for extreme weather conditions. Your contractor should include all the necessary engineering costs in his total price for the installation.

Consider Aesthetics

When it comes to the aesthetics of a solar installation, you’ll find a full range of opinions. It can be a very subjective topic. Some people feel the look of solar panels is quite appealing and progressive, while others think they can severely take away from the attractiveness of a building. It really comes down to how you feel about the look of a solar array.

In many cases, however, you do have some options to improve the overall look of the system or implement some design tools that can effectively hide the installation so most people will never see it. For example, you can tell your contractor you want all black panels to give the system a uniform look, or you can choose to flat mount the system on the roof so no one can see it at all.

Overall, the most successful designs are the ones that are a collaboration between the installing contractor and the facility owner. The contractor will be your partner, expert and advocate through the whole process, but it’s up to you to make the final decision on what’s best for your business.

Solar Design in Progress: Oakley Executive RV/Boat Storage

Oakley Executive RV/Boat Storage in Oakley, Calif., which is expected to open in the fall.

Oakley Executive RV/Boat Storage, being built on 11 acres in Oakley, Calif., is designed to be a full-service, class-A facility serving the recreation-storage needs of the Delta region and greater San Francisco Bay area. Opening this fall, the project features the Solar Support System designed and engineered by Baja Construction Inc. The installation covers 170,000 square feet, delivering 331 shaded parking spaces and supporting a 1.67 megawatt solar park. Solar panels attach directly to the support system, creating shade for parked vehicles. The facility will reap greater revenue from shaded-parking income and the solar energy produced.

Based in Martinez, Calif., Baja designs and engineers solar-support structures and light-gauge steel structures that perform under any snow, wind or soil condition or load. The company can provide a fully installed solar-support system to any jobsite nationwide.
