To employ new solar photovoltaic technologies in products and buildings, many systems need to be adapted. Inspired by the cylindrical shape, in this work we have evaluated the performance of luminescent solar concentrator photovoltaic (LSC-PV) elements with narrow PV cell strips that could be integrated in an outdoor lighting pole. Silicon photovoltaic (PV) cells were attached to the back of bo...

In development of floating photovoltaic generation system, finding a suitable place of installation is as important as development of economically feasible and stable structure. Especially since floating photovoltaic system has its facility floating on water surface, it is extremely important to review the effects of weather conditions such as wind, water flow and floating matters, various fact...

Maximum power point trackers (MPPTs) play a vital role in photovoltaic (PV) systems because they increase the eff iciency of the solar photovoltaic system by increasing the power output. MPPT algorithms are necessary because PV arrays have a non linear voltage-current characteristic with a unique point w here the power produced is maximum. The output pow er from the solar panel varies w ith sol...

The use of solar energy as a source for pumping water is one of the promising areas in the photovoltaic (PV) application. The energy of photovoltaic pumping systems (PVPS) can be widely improved by employing an MPPT algorithm. This will lead consequently to maximize the electrical motor speed of the system. This paper presents a modified incremental conductance (IncCond) MPPT algorithm with dir...

Photovoltaic system (PV) is alternate suitable option against conventional source of generating electricity. A typical photovoltaic system produces the electrical energy in terms of voltage and current. PV system is the environmental protection technique as well as saving of the electrical energy. This system reduces the level of chlorofluorocarbons (CFC) in the environment because it restricts...

This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic. A good number of publications report on different MPPT techniques for PV system most of th...

We describe the development of new, Web-based maps of insolation and photovoltaic energy potential across Canada. The maps will be made available on the Natural Resources Canada website. They are presented for each month and summed for the entire year, for five different surface orientations: a suntracking orientation and four fixed South-facing orientations with latitude, vertical and latitude...
