Q: What are solar panels?: Solar panel is a generic term used to describe a device that collects and converts solar energy into electricity or heat. Photovoltaic module, used to generate electricity Solar thermal collector, used to generate heat Solar hot water panel, used to heat water, often in homes but i guess u mean the ones which generete electricity a photovoltaic module is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. An installation of photovoltaic modules or panels is known as a photovoltaic array. Photovoltaic cells typically require protection from the environment. For cost and practicality reasons a number of cells are connected electrically and packaged in a photovoltaic module, while a collection of these modules that are mechanically fastened together, wired, and designed to be a field-installable unit are known as a photovoltaic panel or simply solar panel. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries (for off grid) and interconnected wiring.

Q: Hi, I want to put some solar light in my yard, and wondering if a 00w solar panel could work for a few 3w dc lights....do i need a battery so they run at night, if so how many lights do u think i can run/ also i see elading solar light: 3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK

Q: Can solar panels be installed on a concert venue or entertainment facility?: Yes, solar panels can be installed on a concert venue or entertainment facility. Solar panels can be mounted on rooftops, parking lots, or even integrated into the design of the venue itself. These installations can help offset the energy consumption of the facility, reduce carbon emissions, and potentially save on electricity costs in the long run.

Q: Can solar panels be used in areas with high levels of air turbulence or strong winds?: Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is important to ensure that the solar panel installation is designed to withstand such conditions. Proper anchoring and mounting systems, as well as reinforced frames, can help secure the panels and prevent damage or displacement due to wind forces. Additionally, selecting wind-resistant solar panel models can further enhance their performance and durability in such environments.

Q: I have to get a lot of information on how solar panels are developed and distributed in America because I have to do two pages on this. Please help me get information in this I really need it!! Thankss...: The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.

Q: How does the snow cover get removed from the panels?: Green energy magically makes the snow transparent. The more I learn about solar and wind, particularly selling excess power back to the utility, the less sense it makes. You'll have noticed, perhaps, that there was no way to store the power from the panels for when it's really needed.

Q: Can solar panels be used for powering Wi-Fi networks?: Yes, solar panels can be used to power Wi-Fi networks. Solar panels generate electricity from sunlight, which can be used to power various devices, including Wi-Fi routers. This allows for the establishment of Wi-Fi networks in remote or off-grid locations where traditional power sources are either unavailable or unreliable. Additionally, solar-powered Wi-Fi networks are environmentally friendly and sustainable, as they utilize renewable energy sources.

Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.: wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .

Q: What about sources for straight forward solar powered products? Excluding toys, garden frogs and outdoorpath lights I have found few useful items for the home. What I have found are solar panels for under $00 each, inverters, rechargeable indoor lights and a few camping/RV products that are interesting. It seems to me that these could help me start to wean the family off the power company. I can't afford to go cold turkey and cover my roof with solar panels and I don't think the HOA would allow me to even if I could. Is anyone using solar on a small scale?: Homemade okorder

Q: Are solar panels worth the investment?: Yes, solar panels are worth the investment. They have numerous long-term benefits such as significant energy savings, reduction in electricity bills, and a positive environmental impact by reducing carbon emissions. Additionally, many governments offer incentives and tax credits for installing solar panels, further enhancing the return on investment.
