The SMA Solar Academy welcomes Alex, fully Alejandro Avellaneda, to the team! As a technical trainer with the Solar Academy, Alex will conduct seminars and webinars, in both English and Spanish, about SMA products, code compliance and installation best practices. Alex holds nearly a decade of experience in the energy industry, most recently a regional trainer and instructor for mechanized rig equipment commissioning, operation and maintenance in the oil and gas sector.
SMA’s highly anticipated Rapid Shutdown System is now available and ready for pairing with the latest Sunny Boy-US and TL-US inverter families. Engineered for use with SMA’s inverter lines featuring Secure Power Supply, this simple, reliable and cost-effective solution achieves all requirements for 2014 NEC 690.12 rapid shutdown.
Oversizing a PV array, also referred to as undersizing a PV inverter, involves installing a PV array with a rated DC power (measured @ Standard Test Conditions) which is larger than an inverter’s rated AC output power (i.e. DC @ STC > AC). It can be a valuable tool for system designers seeking to deliver a maximum amount of energy at a lowest possible specific cost. Reasons for over-sizing PV arrays and important factors to consider are summarized below.
For the second year in a row, I’ve had the notable privilege to speak at Solar Asset Management North America—the most distinct conference for the solar service industry. Like last year, SMA sponsored the event and I was allowed the pleasure to be onstage with some very distinguished colleagues to discuss the key topic of understanding, controlling and driving down the true cost of O&M and Asset Management.
