Q:highest known watt output for solar panels?
in case you raise a dumb-bell a undeniable style of feet, you have expended a undeniable volume of potential, does this variation if the gymnasium exchange into on yet another floor of the construction? Grounding is needed for defense and to dodge floor loops from happening, the quantity of potential produced would not exchange and any adjustments in potential will bring about a risky floor loop attempting to equalize it.
Q:What's the best deal for Solar Energy panels for your home?
Q:can i make a solar panel out of aluminum foil?
You can't make a solar panel to generate any reasonable amount of electricity from that. You need a semiconductor to start with, in order to have something that can generate free charge carriers(electrons and holes) from photons. Then you need a junction which can separate the charges. In principle you could make a Shottky Diode solar cell from copper if you could find a doped semiconductor to bond a sheet of it to the copper. To form a decent electric field there should be a significant difference in work functions between the copper and the semiconductor, this will generally require the semiconductor to be doped. On top of this you would need a transparent conductor (most used are things like ITO or other 'TCOs' - Transparent Conducting Oxides) to be the top electrode to inject replacement charges into the semiconductor to replace the effect of recombination current. In summary, it's difficult to DIY. You generally need complicated machinery to get decent crystal growth and/or doping.
Q:solar panel model HELP!!!!!!!?
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
Q:Increasing Solar Panel Efficiency?
Even the angle of a solar panel can increase it;s out put, if you point it towards the south, it will receive more light (or towards the light source if it is an artificial source) mirrors can also be place and angled around solar panels to gather and reflect more light to the panel, this is often done is solar water heating, but would work with a panel as well. Over all, solar panels are very efficient, it's our way of catching light that isn't.
Q:Generator for solar panels....?
Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.
Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:Solar panel trouble?
you don't need a capacitor. You can connect it to a light directly. Capacitors rarely break. You can check with an ohmeter.
Q:Electricity question about solar panels?
A 500 watt water heater is very small. Most are over 5000 watts. But even a water heater that small would not heat water with a 95 watt solar panel. Inverting the 24 volt to 20 volt would still give you 95 watts of power. A little short of the 500 needed. Sorry. Solar is cool but not practical for large loads unless you install more panels.
Q:Can I build my own Hot Water Solar Panels?
Solar Power is great. I installed it myself about 2 years ago, and you really do notice the change within the first couple months. Building it yourself is actually pretty tricky without the right resources. Some of the guides don't have enough detailed information that you need when you start putting the project together. I was having a lot of trouble until I stumbled upon a site that was offering some great resources for solar DIY projects. I went ahead and added it to the sources section below. It's great and has everything you would need for putting your own solar projects together, including hot water solar panels. Hope this helps!
