Bifacial PV modules convert both front- and back-side irradiance into electricity. This bifacial boost improves solar project performance both in terms of yield and the levelized cost of energy (LCOE). Due to these benefits, bifacial PV modules are...

A principle goal of value engineering is to deliver long-term performance and reliability at the lowest cost practicable. One effective way to reduce the levelized cost of energy (LCOE) in large-scale or commercial and industrial (C&I) solar...

Power engineering is a broad electrical engineering field that covers all aspects of the bulk electric power system, including power generation as well as transmission and distribution. As a full-service engineering firm specializing in photovoltaic...

Pure Power performs many types of power system studies, and the Arc Flash Study may be the most important because it is all about worker safety. However, since it’s not always a code requirement and doesn’t have a direct impact on generation, it is...

EV chargers currently come in three different models: Level 1, Level 2, and Level 3. Level 3 is also commonly known as Direct Current Fast Charging (DCFC). In Level 1 & 2. the EV is connected to AC power, 120V or 240V, and a battery charger in the...

There are many things about EVs that are similar to an internal combustion engine (ICE) powered vehicle, but there are also some important differences and some less understood equivalencies. In this article, I will discuss some of these comparisons...

The ac collection system in commercial roof-mounted PV systems generally extends from the inverter ac output terminals to the low-voltage point of interconnection (POI). The exception is when the system interconnects at medium-voltage levels, in...
