Product description

The Solar System[a] is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.[b] Of those objects that orbit the Sun directly, the largest eight are the planets,[c] with the remainder being significantly smaller objects, such asdwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, themoons, two are larger than the smallest planet, Mercury.

The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earthand Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. 

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Q:Do you need to pay for electricity if you have solar panels?
No standard home can operate on solar panels alone unless there is about an acre or more of them. Plus, they require lots of batteries and complicated switching devices. And, they are very expensive, so rarely pay back their up front cost. Right now, more of a gimmick than a practical solution to power needs in the home. The house you're looking at may use it to power emergency lighting in case the grid went down. Or maybe a small fan to exhaust heat out of the attic. Who knows. Just have to ask.
Q:How do home solar panels integrate into a houses current electricity?
Light striking a silicon semiconductor causes electrons to stream, making power. Sunlight based force producing frameworks exploit this property to change over daylight straightforwardly into electrical vitality. Sunlight based boards (likewise called sun powered modulese prepare immediate current (DC), which experiences a force inverter to get rotating current (AC) — power that we can use in the home or office, in the same way as that supplied by an utility force organization. There are two sorts of sun powered force creating frameworks: matrix joined frameworks, which are associated with the business power framework; and stand-alone frameworks, which encourage power to an office for prompt use, or to a battery for capacity. Network joined frameworks are utilized for homes, open offices, for example, schools and healing facilities, and business offices, for example, work places and strip malls. Power produced throughout the daytime could be utilized immediately, and in a few cases surplus power might be sold to the utility force organization. In the event that the framework doesn't produce enough power, or produces none whatsoever (for instance, on an overcast or blustery day, or around evening time) power is acquired from the utility force organization. Power preparation levels and surplus offering might be weighed continuously on a screen, a compelling approach to gage day by day vitality utilization. Remain solitary frameworks are utilized as a part of a mixed bag of provisions, including crisis power supply and remote force where conventional foundation is distract
Q:Cost of Solar Panels for basement?
If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
Q:The effect of colored light on a solar panel?
Surely the highest volt reading will result from the wave with the largest amplitude, wavelength irrespective? You'd need to know the amplitude of the wave AFTER leaving the colour filter, since different chemicals and pigments in the filter would naturally affect the resulting wave in different ways.
Q:Do solar panels shine/have luster? Please help me. Easy ten points!?
Solar panels reflect less sun than a piece of window glass, and people aren't harmed by the sun's reflection off windows. Also, solar panels tend to be tilted more or less directly toward the sun, so the light that they reflect is back at the sun, not down into the street or yard where people are. Those huge power tower concentrating solar thermal plants have a brilliant light reflected off the boiler. But those are put out in the desert, away from people.
Q:how to know the voltage level of solar panel?
The voltage rating and current rating are part of the specifications for the panel. You will have them listed on the spec sheet. The voltage number is usually the open circuit voltage of the panel, the voltage with no load. The current number is the short circuit current of the panel. In use, you need special electronics, called a Maximum Power Tracker (MPT) controller, which adjust the load to get the most power from the panel, and adjust the voltage output via a DC-DC converter to the optimal conditions to charge the attached battery. how to take batteries as per solar wattage ? sorry, don't understand this.
Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
Q:where could i buy a cheap and low cost solar panel regulator?
try OKorder..i know it sounds corney but someone might be selling one, if not try your nearest hardware store? Like ..lowes..orsomething.
Q:Solar panels for security cameras?
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
Q:Questions about charging batteries via solar panel...?
Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
