Q: I'm about to buy one but I don't really know which one is best for my home.
Talk okorder has good info. What state are you in?
Q: Can solar panels be used in areas with high levels of dust or sandstorms?
Yes, solar panels can be used in areas with high levels of dust or sandstorms. However, frequent and heavy exposure to dust or sand can reduce their efficiency over time. Regular cleaning and maintenance are necessary to ensure optimal performance in such areas. Additionally, advanced solar panel designs and coatings are being developed to mitigate the impact of dust and sand accumulation, making them more suitable for use in these challenging environments.
Q: Can solar panels be installed in areas with frequent power outages?
Yes, solar panels can be installed in areas with frequent power outages. In fact, they can be a great solution to overcome the challenges of unreliable power grids. Solar panels generate electricity from sunlight, which means they can operate independently of the grid during power outages. By storing excess energy in batteries, solar panels can provide a reliable and uninterrupted power supply, even in areas prone to frequent outages.
Q: Can solar panels be used in areas with high levels of windstorms?
Yes, solar panels can be used in areas with high levels of windstorms. However, it is important to ensure that the solar panels are properly installed and secured to withstand the strong winds. Additional measures such as reinforced mounting structures and regular maintenance can also be taken to enhance their durability in such conditions.
Q: I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.
Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
Q: I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?
They consist of a semiconductor junction which has an uneven distribution of charge so it has an electric field in it. When light hits the material, an electron is knocked off from its parent atom and can move around the material. The electric field pushes it in one direction, et voila. You have current! (it's most complicated than that, but it needs quantum physics to understand). In summary, light goes in and DC electricity comes out of the panel. To use it in your house you will need an inverter as well, which turns it into useful AC. Then you need a way of using up the extra electricity you produce when it's sunny but you're not using power Some people use batteries, most people use 'grid tied' systems, plug in to the national grid and sell electricity to power companies that you're not using! Unfortunately, without major subsidies (like those offered in Germany, Japan and soon the UK), solar panels aren't likely to be cost effective. In the UK it costs about ?5-6,000 to install a kWp of solar power and it will make about ?90 of electricity a year. In California it's sunnier, so would make about ?200 of electricity a year, but it's still very VERY expensive without subsidy. On the plus side, technology is improving. Thin film technology can be done at half the price, so I'd say hold on until thin film solar cells go up for sale (right now they only sell them to companies for big projects). Prices should drop by at least half in the coming years if they can make enough to sell to households - and at that price it'll be worth it in places like California.
Q: Can solar panels be used for charging electric vehicles?
Yes, solar panels can be used for charging electric vehicles. Solar panels convert sunlight into usable electricity, which can then be used to charge the battery of an electric vehicle. This enables vehicles to be charged with clean, renewable energy, reducing both emissions and dependence on fossil fuels.
Q: Why does the new 200 Toyota Prius have solar panels at the top of the vehicle?
The solar panel powers the fan in the solar-powered ventilation system. The ventilation system helps to keep your car cool while parked out in the sun. If your car is cooler, then when you get into it after parking somewhere the AC won't have to work quite so hard to get you comfy when you start your car. Less AC use means less hybrid battery use (since the hybrid battery powers the AC), which means that your gasoline engine will run less (to recharge the hybrid battery), meaning better fuel economy for you.
Q: what percentage of sunlight is converted into electrical energy in a solar panel?
Thin film panels are typically 5-7% efficient. Crystalline panels are typically 0-4% efficient. Both types of panels will degrade overtime, so the efficiencies above are only for new panels.
Q: Well, I am looking for a cheap way on building a solar panel, instead of buying by the manufacturing stores. I would like to stay in the budget up to ,000 dollars. I want to have Solar Energy for my house because the sun is always shining. Is there a way I can make the Light power some of my house? What would I need? How much time would it take?Where can I get the items I need?
there is a website that sells a book for $40 thattells you how to do it cheaply check it out just google earth4energy
