No, they capture power released by nuclear fusion from nuclear binding energy in the sun in the form of light photons. These photons knock electrons across the PN junction inside the solar cells, where they become captured and generate a voltage across the solar cells. When those electrons are allowed to flow through an external circuit the captured power becomes available in that external circuit.
They generate no power at all, they just transform power from one form (photons) to another (electricity). They even do it very very inefficiently with most of the power being lost as heat.
However even this small transformation is usually better than none, which would be the case without them.
For what it is worth no "power generating system" (e.g. hydro, coal, nuclear, fusion reactor) can generate any power, they all only transform it from one form to another.

∙ 8y agoYes, in a way. Solar panels work by capturing electricity from sunlight. They don't need any power to run. They produce their own power, which is then stored in a battery, sent to the grid, or used immediately.

Can solar power power your whole house?
Solar electric panels can definitely produce enough electricity to power everything in your home. An "off-grid" house refers to a home that is not connected to the electrical grid and must generate its own power (usually through solar or wind). Though these houses aren't exactly common in North America, there are probably more of them than you think. The number of solar panels you would need to "power your whole house" depends on how many kilowatt hours of electricity your family uses per month.
List two renewable energy resources that are widely used today and indicate how they are used?
Hydro electricity - used to generate power for towns and cities around the world.PV Solar panels - used on the roofs of many private houses to generate electricity, either for their own use or to sell back to the power companies.
How is solar panels cheaper?
Solar panels are cheaper because your consistently producing your own electricity by using solar panels. If you produce more electricity then the electric company will pay you.
Can you build your own solar panels?
I can't, but you might be able to.
How is sunshine free like solar energy?
Sunshine is solar energy. It is free if you collect your own solar energy because nobody legally owns the sun (and nobody ever will), therefore solar energy from the sun is free. However if you depend on a thrid party to deliver the energy to you from a solar power station, it will cost you a maintenance and delivery fee, to pay for the upkeep of the station. However, if you install your own solar panels rather than relying on a third party, it will cost you to install solar panels on your home, to convert your home to using solar energy and to take your home "off the system" (to remove your dependency from nationally-produced power). But it will not cost you anything to use solar energy from your own solar panels. In a couple of years, you would have produced enough personal energy from solar power to make the cost of the conversion worth it.
What is the cheapest way to generate my own electricity for a house?
The cheapest way to generate your own electricity for a house would be to install solar panels. While the upfront cost can be significant, over time you can save money on your electricity bills as you generate your own power from the sun. Additionally, government incentives and tax credits may further reduce the cost of installation.
Why should the use of solar power should be made mandatory in tropical regions?
Solar energy uses a very clean and renewable resource to generate electricity: our very own sun! This means that there aren't really any negative environmental and effects, that it doesn't produce any harmful gases. So to answer why tropical regions should have solar power installed is simply because they are the locations where the heat of the sun has a better chance of reaching the solar panels installed
How many solar panels do I need for a 10kWh Powerwall?
Most Americans prefer to buy a 10kWh Powerwall as a backup power source for their home, so how many solar panels are needed to charge a 10kWh Powerwall? Assuming 400W solar panels are used to charge the Powerwall, the peak hours of sunlight are 5 hours per day. The number of solar panels required is directly related to the solar irradiance and the power output of each panel. 10kWh ÷ Peak sunshine hours per day x 1000 ÷ Rated power of solar panel. 10kWh ÷ 5 hours x 1000 = 2000 ÷ 400W = 5. A 10kWh Powerwall requires 5 solar panels. In this article we will show you how to use this formula yourself so that you can budget your own solar build without the help of a solar calculator.
What do solar panels have in them?
Solar panels are a series of cells connected together.Also you can make your own solar panels because today some manufacturers sell the cells individually.I bought a DIY Guide that helps me make my own solar systems at a fraction of retail prices.If you are interested the site can be reached by using the Related Link shown below.
How can you go solar?
You can go solar by using solar panels to generate electricity. There are a number of ways you can do this. I found this cool site which gives you instructions on how to make your own solar panels. They include a number of different options for hooking it up to your existing electrical system, hooking up just an appliance or to, or being completely "off grid". Here's the site: www.NewDIYSolar.com. Hope you find something useful. Good luck with it!
Is it too expansive to install solar power?
It can be expensive but if you are a do-it-yourself type, you can cut the costs considerably by making your own solar panels. I've just gotten started building my own solar panels and have been able to figure it out from instructions I got on this great website. Gives everything you need to know, materials you need, where to get them, and step-by-step instructions. Here's the site: www.NewDIYSolar.com Good luck!
How can solar energy be used?
Solar energy can be used directly for water heating, or it can be converted to electric energy using photo-voltaic cellsA:Solar energy works by the use of silicon structured panels. These panels can trap the heat from the sun and convert it to more common energy, electricity. The electricity is then channeled to a power plant like building which distributes the energy accordingly. These panels can also be installed in your own home. There are several ways of capturing and using the sun's energy, including photovoltaic cells, active solar energy, passive solar energy and concentrating solar power systems.
