By policy design, consumers are supposed to save money when they invest in solar energy. This paper presents a case study of what happens when a church goes solar and the finances go wrong. Following the installation of solar-photovoltaic panels, the Arizona church—in the Valley of the Sun, among the sunniest places in the country—decreased its energy consumption, but its electric bills went up. Through oral-history interviews of key stakeholders, the author investigates what happened, and what could be done to prevent other religious institutions and nonprofits from experiencing the church’s fate.

As a source of alternative energy, solar energy has apparent advantages, including a renewable, inexhaustible, and environmentally friendly resource. However, it has not become widely spread in the Russian Federation. Among the disadvantages of using solar energy are high equipment cost, low efficiency of photovoltaic solar cells, the generated electrical energy instability. The spatio-temporal variability of solar access causes electrical energy instability. It is possible to increase solar photovoltaic plant efficiency by using a tracking system to change the plant sun's spatial orientation. The paper offers mathematical and simulation models of a solar photovoltaic plant with a solar tracking system that allows the plant to be automatically oriented to the sun by matching the production mode and the solar access level. The use of the azimuth plant control system on the sun will increase the power production of the solar PV plant by an average of 28%. The same value will increase by 40% when using the full plant control system.

Smart Traffic

The objective of this project is to control the traffic signal with help of solar energy. This project has been developed as a model of Traffic light controller. The signals can be controlled through software programs and can be varied depending upon the location. For example some places needs green signal to glow for long time. And some directions need red signals to glow for long time. This can be achieved simply by varying the delay in the software. Solar power is used to provide the power to the solar lights. So this project is very useful to the government to save the power.The solar panel is solar photovoltaic modules use solar cells to convert light from the sun into electricity. Now-a-days, instead of using the power from the supply line for various operations, most of them are going for solar energy source, as it is cheapest.

Photovoltaic module is an important part of photovoltaic power generation, so the quality and reliability of Photovoltaic modules directly determine the whole (PV) power system’s stability. Design a JN5139 as control core based on the solar Photovoltaic modules of WSN sensor node. This paper firstly analyzes the sun batteries testing principle, then from two aspects of hardware and software this sensor node in detail, including hardware JN5139 timing acquisition by the output of solar cell piece voltage, current and bypass the diode loop current, judge battery slice of actual work; Software from main program respectively, AD son conversion program, etc are introduced. With the data of experiment collecting, the node is analyzed and evaluated.

Along with the lack gradually of fossil energy,people began to pay attention to the using of solar energy that easy to obtain and no pollution. Today,a lot of vehicle-mounted systems have begin to use solar photovoltaic panels.But with the driving of vehicle, photovoltaic panels often can’t face to the sun ,unable to get enough direct sunlight. In order to change the fact,writer designed a new system.In this system, we use ambient light detection module and MCU to locate the sun,then MCU controls two motors to make the photovoltaic panel change its orientation,so vehicle-mounted solar photovoltaic panel can change orientation automatically with the light.

Simulation Results

The electrical energy is considered as the main resource for the development of countries. As there are several sources of renewable energy, the solar energy is one of the green energies, which is imperishable. A lot of researchers have been working on the improvement of the efficiency of solar photovoltaic panels in order to generate more electrical power. Tracking the sun position is a solution to increase the power produced by photovoltaic panels. Referring to some measurements, the parallel orientation of the photovoltaic panels with the sun raises the produced power by more than 40%. This article aims first to control their position to track the sun during the day. The control system is based on an induction motor controlled by the Direct Toque Control (DTC) approach. To overcome the conventional DTC drawbacks, a robust DTC-SVM based on sliding mode controllers is the second contribution in this article. The simulation results demonstrate that the robust DTC-SVM with sliding mode controllers offers the best results in terms of ripples compared to conventional DTC approaches.

Solar photovoltaic systems are most commonly used renewable resources nowadays. These pv cells are eco-friendly, pollution free, easy in construction and are compact in size. The solar pv cell generates electricity by simply tracking the sun rays. The main advantage of solar pv cell is that it is dependent on sun light and the sun is available everywhere. The power generated by photovoltaic cell has less efficiency. Thus, this paper proposes the hybrid maximum power point tracker for improving the efficiency of generated energy of grid connected solar pv system.\
