Fires on Amazon warehouse roofs seemingly caused by faulty PV installations

Amazon has made installing solar panels on rooftops a key part of its ESG strategy, but a series of events last year show how challenging greening up major facilities can be.

Between April 2020 and June 2021, solar panels on Amazon fulfillment center roofs caught fire or experienced electrical explosions at least six times. As a result, the company took all U.S. solar rooftops offline last year while it investigated the mishaps.

According to a CNBC report, Amazon hired a consultant to audit its rooftop solar systems in the U.S., Asia-Pacific, Europe, Middle East, and Africa. The study discovered several problems at various sites including mismatched module-to-module connectors, improper installation of connectors, poor wire management, and evidence of water intrusion in the inverters, CNBC reported.

Each fire reportedly cost the company an average of $2.7 million, which included third-party audits of rooftop solar systems, checks on how much electricity they were generating, and repairs for broken or faulty parts.

Despite the setbacks, Amazon remains committed to solar power and continues to monitor the situation, making repairs where needed. As of this April, Amazon had onsite solar at 176 facilities. Its solar program began in 2017.

LPA Architects conducted a post-occupancy evaluation, or POE, of the eSTEM Academy, a new high school specializing in health/medical and design/engineering Career Technical Education, in Eastvale, Calif. The POE helped LPA, the Riverside County Office of Education, and the Corona-Norco Unified School District gain a better understanding of which design innovations—such as movable walls, flex furniture, collaborative spaces, indoor-outdoor activity areas, and a student union—enhanced the education program, and how well students and teachers used these innovations.

Make sure to get your multifamily amenities mix right

One of the hardest decisions multifamily developers and their design teams have to make is what mix of amenities they’re going to put into each project. A lot of squiggly factors go into that decision: the type of community, the geographic market, local recreation preferences, climate/weather conditions, physical parameters, and of course the budget. The permutations are mind-boggling.
