Q:How do solar panels generate electricity?

Solar panels generate electricity through the photovoltaic effect, where sunlight is converted into electricity. When sunlight hits the solar panels, the photons in the sunlight knock electrons loose from their atoms, generating an electric current. This current is then captured and converted into usable electricity for powering homes and businesses.

Q:Can solar panels be installed on farmlands or agricultural fields?

Yes, solar panels can be installed on farmlands or agricultural fields. In fact, many farmers and landowners are increasingly using their land for solar energy production as it can provide additional income and sustainable farming practices. Solar panels can be mounted on ground-mounted systems or integrated into structures like barns or sheds without interfering with farming operations. Additionally, solar installations can offer benefits such as reduced energy costs and promoting environmental sustainability in the agriculture sector.

Q:Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.

Larger solar arrays are made by grouping more solar panels together. There are no large solar panels. They are all about the same size. Do an internet search on solar photovoltaic panels, and you will get hundreds of hits from on line companies that sell them. Most have a sales consultant you can e-mail who will help you decide what you need.

Q:Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks

It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.

Q:Can solar panels be used to power air conditioning or heating systems?

Yes, solar panels can be used to power air conditioning and heating systems. Solar panels convert sunlight into electricity, which can be used to power various appliances and systems in a building, including air conditioning and heating units. This is achieved by connecting the solar panels to an inverter, which then converts the generated DC electricity into AC electricity that can be used to run these systems. By utilizing solar power, it is possible to reduce reliance on traditional energy sources and reduce carbon emissions associated with air conditioning and heating.

Q:Is it really necessary to make solar panels that expensive?

Unfortunately, yes. Solar panels require high-grade silicon which is very expensive. Also, volume sales aren't yet high enough to push down prices. Don't worry though, as people buy them and the technology matures it'll get cheaper. I remember DVD players costing $2000+. Now you can get one for less than $30.

Q:I have a 2V .5W solar panel and I want to get a battery that can be charged by the solar panel that can then be used to power a 2V .5W fan. Ideally I want all the components to be connected and able to run without interaction. I have very little knowledge in regards to this field which is why I have come to yahoo answers. Any help would be greatly appreciated.

batteries are rated via the CCA, chilly cranking Amps the better the CCa the longer it is going to very last, don,t imagine you want a cost Controller as your continuously drawing juice from it, the picture voltaic panel will keep the bat at its top , then even as the daylight is down , the pump will draw off the bat,

Q:Are there any government incentives or tax credits for installing solar panels?

Yes, there are government incentives and tax credits available for installing solar panels. These incentives vary by country and state, but they often include federal tax credits, grants, rebates, and state-level incentives. These incentives aim to promote renewable energy adoption and can significantly reduce the cost of installing solar panels for residential and commercial properties. It is advisable to consult local government agencies or renewable energy organizations to get specific information about incentives available in your area.

Q:Can solar panels be installed on a south-facing wall?

Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is often the most ideal location for solar panel installation as it receives the most sunlight throughout the day.

Q:Can solar panels be installed on drones?

Yes, solar panels can be installed on drones.
