To solve the problem of solar abandoning, which is accompanied by the rapid development of photovoltaic (PV) power generation, a demonstration of a photovoltaic-battery energy storage system (PV-BESS) power plant has been constructed in Qinghai province in China. However, it is difficult for the PV-BESS power plant to survive and develop with the current electricity price mechanism and subsidy ...

Photovoltaic (PV) energy conversion is now recognized to be the most widely accepted method of harnessing renewable energy sources to benefit communities, especially in developing countries. PV arrays provide direct conversion of solar energy into electrical energy without inducing environmental pollution. Recognizing these facts, extensive research and development efforts are devoted to photov...

In this paper, we present a modeling and implementation of new control schemes for an isolated photovoltaic (PV) using a fuzzy logic controller (FLC). The PV system is connected to a load through a DC-DC boost converter. The FLC controller provides the appropriate duty cycle (D) to the DC-DC converter for the PV system to generate maximum power. Using FLC controller block in MATLABTM/Simulink e...

Grid-connected photovoltaic (PV) based power generation technology is being pushed to the forefront as a viable alternative source of renewable energy, particularly in small-scale domestic applications. Due to the variable nature of solar energy, PV usually works well with battery storage to provide continuous and stable energy. However, by incorporating storage with such systems there is a nee...

Since the output characteristics of photovoltaic (PV) system depends on the ambient temperature, solar radiation and load impedance, its maximum power point (MPP) is not constant. Under each condition PV module has a point at which it can produce its MPP. Therefore, a maximum power point tracking (MPPT) method is needed to uphold the PV panel operating at its MPP. This paper presents comparativ...

We consider the problem of automatically detecting small-scale solar photovoltaic arrays for behind-the-meter energy resource assessment in high resolution aerial imagery. Such algorithms offer a faster and more cost-effective solution to collecting information on distributed solar photovoltaic (PV) arrays, such as their location, capacity, and generated energy. The surface area of PV arrays, a...

To date, virtually all photovoltaic (PV) systems employ series-connected PV cells to some degree. A typical 4kW residential solar array, for example, might comprise a dozen series-connected 200-W modules, or roughly 864 cells connected in series. The virtues of this arrangement are (1) that the system’s conductive losses are well managed because the array output current is no higher than that o...

In today’s and future’s electrical power grid system, regenerative energy sources like photovoltaic (PV) power systems consisting of PV panels and grid-connected inverters are very popular in domestic as well as in commercial power plants. High competitive pressure among PV power system providers due to cut inverter’s costs can be observed. Therefore different technical approaches have to be ev...

This paper addresses an economic study of the installation of photovoltaic (PV) solar panels for residential power generation in Santiago, Chile, based on the different parameters of a PV system, such as efficiency. As a performance indicator, the Levelized Cost of Energy (LCOE) was used, which indicates the benefit of the facility vs. the current cost of electrical energy. In addition, due to ...
