know about solar panels?

Question

does anybudy know about solar panels? plz reply me

Answer 1

Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun.

At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants.

Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already.

Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.

How Solar Cells Work by Scott Aldous Inside This Article 1. Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 10. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the "solar revolution" for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately 1,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.

Answer 3

Solar Panels have been around for quite a while now, yet a lot of people seem to be misinformed about what they are, how they work and what are the benefits of owning a Solar PV System.

PV System:

First things first,

Photovoltaic means production of voltage through photoemission, when exposed to radiant energy especially light,
Photovoltaic material is used to build solar cells which are usually packaged in photovoltaic modules; also known as Solar Panels. These modules can be connected to form a photovoltaic array. The system is consisted of a number of pieces of equipment.

Solar PV Systems capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.

Work:

PV systems are made up of a number of components so that light energy is converted into electrical energy.The most fundamental of these components is the cell. A PV cell is made up from layers of semi-conducting material (silicon.) When light shines on the cell, an electric field across the layers is created.

The power of a PV cell is measured in kilowatts peak (kWp). PV cells operate at a low voltage.

A collection of cells is called a module (aka Solar Panel.) Basically these cells are electrically connected, this connection increases the voltage and makes the module usable in a system.

An electrically linked collection of modules is an array. The ”size” of the array varies depending on the system requirements and normally dictated by the input characteristics needed for the inverter.

Benefits:

Economical benefits: Since the electricity will be powered by Solar power the electricity costs will be reduced significantly.
If your system is producing more electricity that you need, the electricity that is not used is sent back to the grid. So basically, it’s like you are selling your unused electricity back and earning money from it.
If the home isn’t connected to the national grid, the system can store the excess electricity in batteries to use when you need it.

Environmental benefits: You can cut your carbon footprint, since solar electricity is a form or renewable energy, it doesn’t release any harmful carbon dioxide or pollution.

Cost:

The cost of a system varies depending on the Installation company and the products used.
There are other factors that affect the cost, for example; if a system size is 4kWp it is going to cost more than a 2kWp, however it is obviously going to generate more than a 2kWp, hence helping you save more and earn more.

Maintenance:

Solar panels require very little maintenance, most importantly they should be kept clean from dust and debris. It is also important to manage any growth from trees. Overshadowing from neighbouring obstacles will hinder the performance of your system and ultimately will affect the kW’s that the system generates.

Answer 4

Solar Panels are groups of Solar Modules mounted together.

A solar cell is one cell.
A solar module is a group of cells mounted in to a sheet
A solar panel is a group of solar modules connected together on a rack and normally placed on the roof etc.. as a unit and can be called a solar array.
A solar array is a group of solar modules or solar panels all mounted and wired together to form a single unit.

Like a battery bank is a bunch of batteries hooked together and the batteries are made of cells.

Was that what you wanted to know?

Answer 5

Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.

Answer 6

Yeah, enough to be dangerous. Solar panels for space? Solar panels for the home? What's your question about solar panels?

Answer 7

Solar Panel is a combination of solar cells also called photovoltaic, they convert the sun-rays into electrical energy. Solar industry is growing very fast around the world with increasing demand of energy. Solar power is widely accepted as renewable source of energy and it is Eco-friendly energy source. It is hot topic on internet now a days there are many articles about this.

Answer 8

Solar Panels are made using Silicon and Boron strips. Sunlight excites the electron in outermost octat and by Boron an empty hole is created inside this panel which helps the electron movement and hence generation electricity.

Answer 9

Solar panels use photovolactic cells to convert the sun's energy into electricity. When the photons in sunlight hit the silicon atoms contained in the cells, their energy is transferred to loose electrons, making them break away from the atoms.

Answer 10

The short answer is nobody does. Solar panels just generate electricity and only when the sun is shining
