Solar collector : A device designed to absorb incident solar radiation and to transfer the energy to a fluid passing in contact with it, usually liquid or air.
Flat – Plate Collector : A typical flat-plate collector is an insulated metal box with a glass or plastic cover (called the glazing) and a dark-colored absorber plate. These collectors heat liquid or air at temperatures less than 180°F.
Solar Energy Storage:-
Methods of storage such as sensible, latent heat &
thermochemical storage,selection of method of storage,
properties of storage materials and different arrangements of
storages
Solar thermal power generation systems use mirrors to collect sunlight and produce steam by solar heat to drive turbines for generating power. This system generates power by rotating turbines like thermal and nuclear power plants, and therefore, is suitable for large-scale power generation.

Now a day with the growing population and energy demand we should take a renewable
option of energy source and also we should keep in mind that energy should not cause
pollution and other natural hazards.
In this case the solar energy is the best option for us.
India is a highly populated country, so we should take the advantage of such an energy
which requires a very less space to produce energy efficiently. In this case solar tree
could be the best one for us.
We can also use the technique called “SPIRALLING PHYLLATAXY” to improve the
efficiency of the plant. It can be applied in street lightening system, industrial power
supply etc. It is much better than the traditional solar PV system in area point of view
and also more efficient. So this will be a very good option and should be implemented.
However, the main problem associated with tapping solar energy is the requirement to
install large solar collectors requires a very big space. To avoid this problem, we can
install a solar tree in spite of a no of solar panels which require a very small space .
Space Radiation & It's Effects On Space Systems & Astronauts Technical Traini...Jim Jenkins
This course is designed for technical and management personnel who wish to gain an understanding of the fundamentals and the effects of space radiation on space systems and astronauts. The radiation environment imposes strict design requirements on many space systems and is the primary limitation to human exploration outside of the Earth's magnetosphere. The course specifically addresses issues of relevance and concern for participants who expect to plan, design, build, integrate, test, launch, operate or manage spacecraft and spacecraft subsystems for robotic or crewed missions. The primary goal is to assist attendees in attainment of their professional potential by providing them with a basic understanding of the interaction of radiation with non-biological and biological materials, the radiation environment, and the tools available to simulate and evaluate the effects of radiation on materials, circuits, and humans
The impact of coloured filters on the performance of polycrystalline photovo...IJECEIAES
Photovoltaic modules behave extraordinarily by transforming part of the visible spectrum into electrical energy, and their efficiencies are affected by the nature of radiation (light) reaching them. When light strikes a photovoltaic cell, this light may go through the cell without been absorbed if it is too energetic or if the light possesses low energy it will be absorbed by the cell and cause the electrons to twist and vibrate in their bonds without dislodging them, hence causing the cell to heat up which ultimately leads to a decrease in its overall efficiency. This study is aimed to investigate how photovoltaics respond to different wavelengths of light. For the study to achieve its aim, colour filters were used to ensure that only a particular wavelength of light reaches the photovoltaic module at a time. In the process of collecting data from the solar panel, the solar panel was placed horizontally flat on a platform one meter above sea level facing the sun. Data was first obtained from the solar panel without the filters and after that with the filters placed one at a time and data collected accordingly. The amount of solar power and solar flux anytime a different colour filter was placed on the solar panel were measured. Among the coloured filter used yellow produced the highest efficiency, while blue produced the least efficiency. However, the solar panel was still more efficient when exposed to the natural spectrum.
Dual Axis Solar Tracking System with Weather Sensorijtsrd
Energy crisis is one in every of the major problems in world developing countries like Republic of India. Theres a huge gap between generation and demand of current. Nearly half of the population of the country cannot get the power supply. Renewable energy is one of the answers to solve this issue. Solar power is one in every of the foremost effective resources of the renewable energy that might play a big role to resolve this drawback. This analysis presents a performance analysis of the dual axis solar tracking system using Arduino and led and servo motors. The most objective of this research is whether the solar tracker is better than a solar panel. This work is split into 2 light dependent resistors LDR is employed to observe the almost source of illumination from the sun. Two servo motors put together accustomed move the electrical device to most source of illumination location perceived by the LDRs. In the other half, the software part is written by using C programming language which head towards to the Arduino UNO controller. The result of the solar tracking system has analyzed and compared with the mounted or static solar panel found higher performance in terms of current, power and voltage. Therefore, the solar tracking system is evidenced additional sensible for capturing the most daylight provide for star gathering applications. The result showed dual axis solar tracking system made further 10.53 watt power compared with mounted fixed and single axis solar tracking system. Components hardware and computer code.
