Snow Considerations and Design Criteria for Ground-Mount PV Projects

January 24th, 2019|

With team members from all over the country, and even the world, SEIPS can say that we’ve worked on PV systems in many types of weather and climate. Now that we are deep into wintertime here in the northern hemisphere, appropriately we thought we’d share some thoughts on the various impacts that snow […]

SEIPS Tech Tips: Civil Engineering for Solar – Storm Water Permitting

November 29th, 2018|

One of the most common requirements for utility-scale solar farms is the need to control runoff during rainfall events, and sometimes after construction activities.  Permitting requirements generally start at the top with the U.S. Environmental Protection Agency, and specifically the National Pollutant Discharge Elimination System, […]

SEIPS Tech Tips: Meter Selection for Solar PV Systems

May 31st, 2018|

by Joe Villacci – SEIPS Technical Manager

Choosing the correct meter for electrical testing means paying close attention to the specifications of the meter, testing requirements, and site conditions. Functional options, voltage, current, and safety ratings can vary dramatically between meters, which can easily lead to […]

SEIPS Tech Tips: Reducing Solar PV Costs Through Quality Assurance

February 12th, 2018|

Developers in the solar PV industry face tough challenges as costs fluctuate in their capital expenditure column. In contrast, the most controllable item in their estimates can be the design and installation process itself, and specifically quality. Through a targeted quality campaign, costs can be controlled by implementing relatively small but important steps throughout the […]

SEIPS Tech Tips: Torque advice for PV Installers – One Grunt or Two Grunts?

January 17th, 2018|

by Brian Mehalic – SEIPS Senior Technician

I inspect a lot of PV systems, and the most common problem I see is electrical connections not being properly tightened.  This is by no means a PV-specific problem, attested to by the addition of Section 110.14(D) in the 2017 National Electrical Code.  I’m paraphrasing here, but […]
