Peru is a country with plenty of renewable energy sources. However, its power demand depends on more than 50% of fossil fuels. Specifically, the power coming from the sun only represents 1% of the Peruvian energy matrix even though the territory has high radiation indexes. Therefore, the current analysis aims to search for the research situation of photovoltaic energy. Hence, this research looked for literature from RENATI and EBSCO, which provided 398 pieces of academic investigation. After applying the Prisma methodology to select the most relevant thesis and papers, we analyzed 48 elements. We found that the on-grid technology was the most viable in economic terms for projects related to business and electrification. At the same time, off-grid systems have been preferred for sanitation applications. Nonetheless, all the reviewed literature showed that photovoltaic technology positively impacted the environment and was as effective as conventional sources.

The aim of this paper is to provide a theoretical analysis on the mechanical power of the mass spring’s system. Some tests are conducted to experimentally evaluate the theoretical analysis and to investigate the mechanical energy ability of this concept. The authors suggest a system used for applications of energy harvesting from roads. The system is able to transform the kinetic energy produced by the passage of vehicles on the road for electrical energy based on the mass-spring using two technologies. The hybrid system has two goals. First, supply the entourage by a mechanism to produce significant electrical power used mainly for public lighting. A device is also provided for storing electrical energy for later use, for home lighting at night or in the case of bad weather. Second, the piezoelectric subsystem controls the spring’s health through analyzing the amplitude and shape of the voltage generated by a piezoelectric material. Finally, an experimental validation of the designed smart speed bump is presented.
