COVID and its related supply-chain issues are having various impacts on the installation and inspection of alternative-energy systems, including PV.
With the rapid reduction in the costs of renewable energy generation, such as wind and solar power, there is a growing need for energy storage technologies to make sure that electricity supply and demand are balanced properly.
There are no one-size-fits-all solutions to the ground fault-protected main circuit breaker issue. Diligent attention to the requirements in the NEC and the equipment in the existing installation is required.
The National Electrical Code requires several systems to reduce the possibility of fires in PV systems and to protect fire fighters.
Comprehensive antimicrobial performance test standards are under development for devices, from the performance of UV lights to bipolar ionization.
This article will examine some of the basic electrical calculations used to photovoltaic validate system design (based on the 2017 NEC)
The module and string voltages and the inverter DC inputs are critical issues since we will be experiencing widely varying weather conditions throughout the country in the years and decades ahead.
EV charging stations, “Charge Points” (after the ChargePoint brand), “Level 1/2/3” Chargers, Superchargers, DC Fast Chargers, CCS Combo Systems, and SAE J1772 Connectors, all refer to Electric Vehicle Supply Equipment or EVSE.
Starting in this article, we’ll enter the forest and start looking at the individual trees (PV equipment and NEC requirements) in some detail.
