People who say “build it and walk away” are seriously incorrect when it comes to Solar-PV assets. At a cursory glance, Operations & Maintenance (O&M) cost on Solar-PV installation as portion of the overall system cost structure is relatively low. One can attribute this low operations and maintenance cost to not only fewer moving parts and existing manufacturer warranties but also to the nascent nature of the installation base (the majority of Solar-PV installations being less than 10 years old in North America) and the lack of well-established O&M methods.

As renewable energy adoption increases in the market place, the term “curtailment” has become commonplace in the vernacular of those in the Solar & Wind energy markets. Curtailment refers to the involuntary reduction in power generation forcing the generating source to produce less power than it otherwise would have with its available resource. Renewable energy curtailment levels in North America is generally around 4% or less. [ 343 more words. ]

Solar PV Assets can be viewed as an annuity with variable cash flows. The variability in cash flow can be attributed to failures or performance degradation of on-field Solar-PV panels, Balance of system (BOS) components, deviations from expected weather patterns and other extraneous factors. Asset Owners and Managers are often confronted with the objective of maximizing asset utilization i.e. meeting expected yearly cash flows and more importantly meeting investment ROI across its expected lifetime.

The Sustainable Energy for All initiative (SE4ALL), launched by the UN in 2012, seeks to achieve a) Universal access to modern energy services b) Improve energy efficiency and c) Increase renewable energy contribution to the global energy mix by 2030. BNEF (Bloomberg New Energy Finance) reports that 70% of the new power capacity built between 2013 and 2030 will be in renewable sectors; 75% of this renewable capacity is expected to be from Solar & Wind Energy projects.

Variability and associated Grid Imbalance caused by Solar-PV Technologies remains a key bottleneck for High Pe*******on Solar Deployment (HPSD). With Renewable energy investments in leading global markets expected to grow by 50% by 2020, the global demand for Battery storage is expected to follow an asymptotic pattern. BCG (Boston Consulting Group) projects annual global sales of storage technologies to grow from €6 billion by 2015 to €15 billion by 2020, and €26 billion by 2030. [ 715 more words. ]

In today’s world, a lot of machines and associated infrastructure around us are labeled “SMART” – smart inverters, smart grids, smart factories, smart cars, smart transportation, and smart city to name a few. So, what does it take for a machine or infrastructure to be smart? Smart machines or infrastructure are defined simply as systems (or system of systems) that react to external stimuli and more importantly learn, readjust and evolve to the stimuli received to support one or more function(s).[ 341 more words. ]

The National Energy Modeling System (NEMS) developed by the Energy Information Administration (EIA) of the U.S Department of Energy (DOE) is a computer based energy-economy modeling system. The model is used by EIA to project energy supply and demand economics for the next 25 years – the time period for which the technology, demographic profile and economic conditions are fairly well understood to represent the energy market within a reasonable degree of confidence .NEMS models the complex interactions of the producers, consumers, intermediaries, technological advances and energy policies to establish supply-demand equilibrium.

The amount of sunlight incident on a PV module determines how much electrical energy it produces. Since the position of the sun is constantly changing as it moves across the sky, the angle of incidence (AOI), the angle between the sun vector and the surface vector, is also constantly changing. Energy production is maximized when the PV module is pointed at the sun (using tracking systems). [ 270 more words. ]

Solar Photo Voltaic (PV) modules and systems convert sunlight to electric energy. When sunlight strikes a PV module, it produces a voltage at its output terminals. If a load is connected to these leads, current flows. Electric power is measured by the product of voltage and current. The duration and intensity of sunlight incident on a PV module determines how much electrical energy it produces. [ 248 more words. ]
