Abstract:

The development of photovoltaic energy requires a lot of land. To maximize the land use, agrivoltaic systems that combine an agricultural and an electrical production on the same land unit are developed. A demonstrator was built in Montpellier (France) with dierent experimental arrangements to study the impact of a xed and a dynamic solutions on the crops below the panels. The eect of shade on lettuces appears to be positive with a Land Equivalent Ratio greater than 1. To extend the experiment to other crops, the crop species best adapted to the agrivoltaic system are identied. The shade toler

However, conventional utility-scale PV requires large swaths of land to be occupied for decades which prevents the land from producing food or performing vital ecosystem services. Co-location of PV with crop cultivation is an emerging strategy for mitigating the land use of PV. In order to optimize this strategy, the impact of the plant growth-related soil properties need to be quantified. To this end, the first portion of the thesis invest

This bachelor thesis consists of a field study conducted in the canton of Machacamarca close to La Paz in Bolivia. The global climate change has affected the weather in the area which has caused higher temperatures, irregularity in precipitation and unexpected frost. This has complicated the traditional cultivation methods and affected the harvest yield. One of the more important sources of income in the canton is the local diary that is processing milk from the local farmers.

Abstract:

A photobioreactor has been designed and developed to efficiently utilize solar irradiance through spatial dilution of sunlight. The concept of spatial light dilution is simple: incident sunlight is spread over a large surface area, thus reducing the photon flux density of the light. The implementation of this technique, however, is difficult. The reactor described within uses a new approach to spatial light dilution, utilizing recently-developed optical components to diffuse concentrated sunlight inside an algae culture. Preliminary productivity tests indicate a 2-3 fold increase in produ

The process of implement a model of Machine Learning will be reviewed step by step: to collect the data, to pre-process the data in order to make it able to use as input for the model, to divide the data into training data and testing data, to train the Machine Learning algorithm with the training data, to evaluate the algorithm with the testing data, and to make the necessary changes to achieve the best results. The thesis will start with a brief introduction to sola

Abstract:

Solar energy coupled with energy efficiency awareness can be an important step to achieving the final goal of having a sustainable environment in the country. Together with a good energy policy including regulations, this goal can be achieved as it will help consumers make more rational decisions when it comes to new technology. A key problem identified in this work is the lack of awareness and strict energy policies. The current funds put in place are not mobile and have not got to a large number of people. The government’s regulations on the other hand are not strict. This report aims to imp

Abstract:

Before vehicles were heavily relied on coal, fossil fuels and wind for power. Now, they are rapidly being replaced by electric vehicles and or plug-in hybrid electric cars. But these electric cars are still faced with the problem of energy availability because they rely on energy from biomass, hydro power and wind turbines for power generation. The abundance of solar radiation and its use as solar energy as a power source in driving these rapidly increasing electric cars is not only an important decision but also a necessary condition for eradication of environmental pollution. This study pre

Abstract:

Renewable energy (RE hereafter) has been observed as a potentially significant new source of jobs and rural growth in both OECD and BRICs countries, and a means of addressing environmental and energy security concerns. The global deployment of RE has been expanding rapidly. For instance, the RE electricity sector grew by 26% between 2005 and 2010 globally and currently provides about 20% of the world's total power (including hydro-power) (OECD, 2012). Rural areas attract a large part of investment related to renewable energy deployment, rending to be sparsely populated but with abundant source

Abstract:

The solar industry has grown considerably in the last few years. This larger scale has introduced more problems as well as possibilities. One of those possibilities is analyzing the data coming from the sites that are now being monitored, and using the information to answer a variety of questions. We have four questions which are of prime importance identified in this thesis: 1. Can data from customers be trusted? 2. Can we use data from existing sites to determine which sites need the most improvement? 3. Can we implement a location-based algorithm to reduce the amount of false positives for

Abstract:

Photon energy upconversion (UC), a process that can convert two or more photons with low energy to a single photon of higher energy, has the potential for overcoming the thermodynamic efficiency limits of sunlight-powered devices and processes. An attractive route to lowering the incident power density for UC lies in harnessing energy transfer through triplet-triplet annihilation (TTA). To maximize energy migration in multicomponent TTA-assisted UC systems, triplet exciton diffusivity of the chromophores within an inert medium is of paramount importance, especially in a solid-state matrix for

Abstract:

The development of products which enable passive solar-energy air-heating to be integrated into the heating strategies of public, commercial and industrial buildings is described. These buildings are, in general, only occupied significantly during the day; consequently the bulk of heating demand coincides with the period of solar gain. In these circumstances collected solar heat should be delivered with the minimum of delay. The design and operation of units which are capable of supplying solar heated air in this manner is outlined. These are passive, naturalcirculation air-heating collectors,
