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: Can solar panels be installed on a swimming pool?
- Yes, solar panels can be installed on a swimming pool. In fact, many pool owners choose to install solar panels to heat their pools and reduce energy costs. The panels absorb sunlight and convert it into energy to heat the water, extending the swimming season and making the pool more comfortable for users.
- 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: I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
- Q: we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.
- Solar Energy Is School! It's School To Go Solar!
- Q: I need a 2v (500-800ma) solar panel that in can fit on a 24inx4in flat surface. Where can i get one this size and with this power?
- Hey Jeff, what you're talking about is frequently referred to as a, solar battery maintainer. There are lots of places that make and sell them, I have seen them in many auto parts stores and truck stops along the freeways. Go to google and search for a solar battery maintainer, they come is sizes similar to what you are searching for, but it will be difficult to find one that is not over 4 wide. Lots of them are about the size of the top of a shoe box, maybe 2 X 6, and come with a cigarette lighter cord attached. A 2 volt model at 500 ma, or /2 amp, works out to about 9 watts, assuming the 2 volt nominal voltage panel is actually optimized for 8 volts, as most of them are. These devices are designed to sit on the dash board of your car and keep your battery charged if you leave the car for a long period of time, like at the airport for a week in the winter. They actually work for that, we've used one before. What are you planning on doing with it? Charging a battery or running a device directly? Remember if you hook it straight to a device, and the current requirements of the device are less than the available sun will develope with your panel, the voltage may climb to a level too high for your device. If you're charging a battery, this does not cause a problem. Another option is to build your own. It can be a lot of work for just one panel, I've not done it myself, but there are videos on the subject. That device in real goods is a flexible panel, known in the solar world as, Amorphous. They are still a bit experimental, the ones they made a few years ago did not hold up as well as the solid ones, and they are expensive. You can get a /2 amp maintainer for around $25. Good luck Jeff, and take care, Rudydoo
- Q: I hooked up a 2V solar panel to a small relay. The relay switches at 9V. When I have light shining on the panel it puts out aorund 3-4V, but when I hook it up directly to the relay it drops to V and doesn't switch the relay. Why? and How do I fix it?-2V Mono-Crystalline Solar Panel -JWD 7 4 reed relay
- There is no ampere output listed for the solar panel. There is specs indicating the relay has a 200 ohm coil. This means the current required for the relay is 0 ma. The solar panel should supply that much. Check the resistance of the relay coil. It sounds like you have the relay coil in series with another resistance, such as a loose connection or a corroded connection. If you can, disconnect the wires from the solar panel and twist the two wires connected to the relay coil, and read the resistance of the two wires connected at on end. A high resistance will indicate a problem in the wires. TexMav
- Q: Are solar panels suitable for residential use?
- Yes, solar panels are highly suitable for residential use. They provide a sustainable and renewable source of energy, reduce electricity bills, and contribute to a cleaner environment. Additionally, advancements in technology have made solar panels more efficient and affordable, making them a practical choice for homeowners.
- Q: Im fourteen and looking for a career I already know solar panels capture the sun and turn it into energy but i would like to know more.
- light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work
- Q: I am looking to run 2 basic shoplights, each with 2- 32 watt T8 flourecent tubes for 6 hours a day for an indoor garden. Location WI.
- Excellent answer from Server Room above. I notice that you mention 45-watt panels, suggesting that maybe you are considering the kind of kit that comes with 3 5-watt panels. I'd recommend against that, as the type of panel that comes in those kits tends to be optimistically rated, and not durable, either. The best way to go for this sort of thing is to use grid power. Then if you want to offset your usage with grid-tied solar, that can be an independent consideration.
- Q: I am intrested in buying solar panels to save a buck and even maek some money off of it but I was wondering what kind? How Much? How Many? Are they easy to install? Whats the best brand? I want alot of information on this if anyone can give me some help on it in a user friendly way it would be appreciated!
- If okorder and search for solar panels, they list companies that sell solar panels and you can compare prices there.
