FOCUS QUESTION Description of the building product CITATION http://whatis.techtarget.com/definition/solar-power NOTES Definition: Solar is an energy efficient device that collects the sun’s light on the day then convert it to energy for use PV; photovoltaic are also called solar cells, It is used to convert sunlight directly into electricity. The name PV comes from the process of converting light (photons) to electricity (voltage), this is called the PV effect. Reflection Relevance for task FOCUS QUESTION Attributes that lead to energy efficiency CITATION https://en.wikipedia.org/wiki/Solar_cell_efficiency NOTES The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and
When the sunlight hits on the solar cells which made from crystalline silicon, a semiconductor doped with impurity atoms. This solar cell will separates positive and negative charge carriers, which in turn produces direct current. The shortage of this method is that there no effective storage solution for it therefore converted electricity will be straight used by consumers as discussed in the grid-connected systems. CSP transform the sunlight into heat by using mirrors to concentrate the rays. The heat energy is then used to produce steam that drives a turbine same as conventional coal power plant with the differences of using heat energy from fossil fuels and sunlight rays.
3.1History Charge controller is a device preventing batteries from overcharging and over-discharging. One of the most common problems of batteries is that they cannot be discharged excessively or recharged too often. A charge controller controls the charge by managing properly the battery voltage and current. Charge controllers are intended to protect the battery and to deliver it as longer life as possible, while keeping the photovoltaic system efficiency. It should be noted that charge controllers only control DC loads.
This has led to a switch from using conventional means to generate power to the new renewable energy source. Researchers has developed cost efficient ways of collecting and storing solar energy (Solarenergy.com 2014). The invention and development of solar panels and batteries enhances the harnessing and storage of energy from sun. Solar array panels are being utilized in harnessing radiant energy and then the collected energy is stored in the batteries simultaneously. The stored energy can be used to operate the machines and run
Solar Panels made from photovoltaic cells ( PV). Simply broken-down photo means light and voltaic related to the production of electricity. Solar Photovoltaic (PV) technology enables the creation of electricity using light intensity. PV cells have at least two layers of semiconductors, one that's positively charged, and one is negatively charged. When the light shines on the semiconductor material the electric field across the junction between these two layers causes electric current to flow.
A hybrid electric vehicle is defined as the vehicle with two or more sources to drive the vehicle. The sources may be diesel, electricity, gas, etc. The hybrid vehicle contains rechargeable batteries which can be recharged when necessary with the help of the electric source externally. Now-a-days, rapid changes and advancement in the motor drive and energy storage technology increases the production of plugin hybrid electric vehicle (PHEV). The proposed topology is used for on-board chargers of the batteries.AC-DC converter with power factor correction fed with the isolated dc-dc high frequency transformer converter is used as the main component for on -board charger in PHEV.
Solar power’s uses are quite eclectic. From electricity (from pv or photovoltaic cells) to heat (solar thermal collectors). In places where there is no electricity grid, solar power can be used. For example, solar energy can be used to get a spaceship’s source of energy through a satellite, or even distill water in rural areas that do not have a lot of clean water. they don 't require a lot of maintenance!
Solar panels are made of photovoltaic cells, what convert sunlight into direct current electricity throughout the day. And that energy moves to inverter, this device converts the direct current electricity what generated by the solar panels into the alternating current electricity. After generated, the energy goes to electrical panel. The electrical panels is also called as breaker box. The alternating current electricity is sent to electrical panel to power our lights and
Abstract Solar Power Satellites (SPS) converts solar energy in to micro waves and sends that microwaves in to a beam to a receiving antenna on the Earth for conversion to ordinary Electricity. SPS is a clean, large-scale, stable electric power source. For SPS Wireless power transmission is essential. WPT contains microwave beam, which can be directed to any desired location on Earth surface. This beam collects Solar Energy and converts it into Electrical Energy.
Introduction In the world, main form of source of energy that is used for the production of electricity is unrenewable sources. But, they have the main disadvantages of being limited and the environmental pollution. The other form of energy is the renewable energy, which includes solar energy, wind energy, wave energy, hydro-electricity, bio mass energy, tidal energy, geothermal energy etc. These are renewable and also environmental friendly. Sri Lanka is a country which is mostly depended on hydroelectricity and also coal together with a domestic scale solar energy and a little wind energy.
