Energy Conversion Devices

Photovoltaic Cells

Photovoltaic cells connect together to create photovoltaic panels or modules and are usually contained within a sealed unit with the panels themselves being covered with a thin glass sheet to protect them. Photovoltaic panels are also referred to as solar panels or solar PV panels. At the heart of a solar panel is the principle of the photovoltaic effect which occurs in the constituent materials.

Solar Panel Power

Solar panels are able to harness light from the sun and transform it into DC current. This current is then converted using an inverter into AC voltage if it is to be used for most domestic appliances. Solar panel power output for home use can range from between 175 watts and 235 watts each with high powered solar panels producing around 315 watts. Of course, to achieve the desired output a solar panel system must be configured which connects several solar panels together within a dedicated and optimized system to increase and control output wattage.

Renewable Energy

What is solar energy?

Solar power and other renewable energies are becoming more popular around the world as interest in alternative energies and reducing greenhouse gases grows. Solar power can be obtained in a number of ways by gathering the sun's energy.

What equipment do I need?

Photovoltaics is the method of direct conversion of light to electricity. Some substances manifest a property called the photoelectric effect which causes them to absorb photons and release electrons which can be captured to produce an electric current. This is the principal behind solar energy where a surface with this property is exposed to the sun to absorb photons from natural light available to generate electricity. This need not be confined to laboratories and may even be used to generate electricity for your own home.

Solar Energy

Solar energy can be defined as the generation of electricity using energy from the sun as the source. The generation of electricity using energy from the sun is achieved by utilizing the photovoltaic effect. The photovoltaic effect is a reaction to sunlight exhibited by semiconductors such as cadmium telluride crystalline silicon.

Solar Energy Principles

The principles of generating solar power rest on the photovoltaic effect exhibited by the semiconductors used to build photovoltaic modules. The photovoltaic effect occurs when photons from the sun are absorbed by semiconductors such as cadmium telluride or crystalline silicon. They respond by producing electrons in DC voltage and are used to build photovoltaic modules which can pass this DC voltage through inverters which convert them in to AC voltage. Photovoltaic module prices depend on their size, application and power load requirements.

Solar PV Panels

Solar photovoltaic panels are also referred to as solar PV panels, photovoltaic panels or simply solar panels. The term 'photovoltaic' refers to the electrical effect displayed by the semiconductors used to construct solar panels. The photovoltaic effect occurs when photons from the sun are absorbed by semiconductors such as cadmium telluride and mono-crystalline silicon. These semiconductors react by emitting electrons that can be used to supply DC current. This current must be converted to AC if solar panels are to be used to supply solar energy in your home.

Solar Energy Benefits

Introduction to disadvantages of solar energy

Solar Energy has many advantages and disadvantages so it is important to weigh up both sides in order to see if it's the right power to use for your household or business.

Why solar panels?

Renewable energy and energy efficiency are high on the agenda with today's rising fossil fuel prices. Aside from the feel-good factor of knowing that one's efforts are saving the planet, what are the benefits of getting solar energy up and running?

Pros of solar panels

Solar energy has been with us for over 55 years and over that time, the materials used to produce it have greatly changed. Recently the solar energy materials and solar cells available to build a solar power generation system have developed at an accelerated rate. Consequently, staying fully informed about developments in the solar power market is more difficult than it used to be.
