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.
The Solar System also contains smaller objects.[d] The asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc, which are populations of trans-Neptunian objects composed mostly of ices, and beyond them a newly discovered population of sednoids.

- Q: Any recommendation for best solar panels?
- I have 3 ARCO solar panels and a wind generator on the Boat and it's all I need to live comfortably on 2 volts.
- Q: Are there any health risks associated with solar panels?
- No, there are no significant health risks associated with solar panels. Solar panels do not emit any harmful substances or pollutants that could pose a threat to human health. However, it is important to handle and install them properly to avoid any potential accidents or injuries.
- Q: ok im going off grid and will have my fridge and stove running on propane but im trying to figure out that at night i want to be able to run my 32 inch lcd tv a internet modem a playstation 3 and 2 laptops and a light or 2 and maybe a floor fan through solar power and i would like to be able run my tv and stuff up to 8 hours in to the night and so i just want to know how many batterys and solar panels i need or how many watts system do i need im running all this on one outlet now at home so i know its under 20 amps and i think i use about 000 watts an hour im not sure so thats why im asking i really need help with this i hope i dont need a $5,000 system thats crazy im only wanting to spend like a $000 please dont explain math figures or a bunch of complicated garbage to me i just want a straight answer on what i need to do to be able to do this thank you!
- Buy a device called a kill-a-watt to measure exactly how much power you use. If you get a systemt to put out 000 watts, it's going to be more than you need, and you'll waste your money. 20 amps is 2200 watts (assuming a 0 volt circuit), which is even more. That will be very pricey. Get the kill-a-watt so that you don't spend more than you need to on solar panels. The cost of the kill-a-watt is almost nothing compared to what you'll be spending on the panels. If I had to guess, 500 watts would run all those devices at the same time.
- Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
- It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
- Q: I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q: How much energy can solar panels produce?
- The amount of energy that solar panels can produce varies depending on various factors such as the size and efficiency of the panels, the location, and weather conditions. However, on average, a typical residential solar panel system can generate around 10 to 12 kilowatt-hours (kWh) of electricity per square meter per day.
- Q: Can solar panels be easily removed and relocated?
- Yes, solar panels can be easily removed and relocated. They are typically designed to be modular and can be uninstalled and reinstalled at a different location with relative ease.
- Q: i have a fountain system that has a small electric pump. its made to be close to a house but i want it across the driveway and i dont want to run electrical over there.is there a small solar panel that i can get fairly inexpensive to mount on a nearby tree and be able to plug the pump into it?
- You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
- Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
- solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
- Q: How do solar panels perform in cloudy weather?
- Solar panels do generate electricity even in cloudy weather, although their efficiency is reduced compared to sunny days.
