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:Build your own solar panel, scam or truth?
Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
Q:Is getting solar panels worth it for your home?
It strongly depends on where you live. In California or Hawaii, for example, solar can be cheaper than the power company, even without subsidies. Any incentives you get just make it better. Whatever you do, like any construction project, get 3 bids from different companies. If there are not 3 companies in your area, you are probably in a poor location for solar. Avoid any company that does a hard sell and tries to get you to commit immediately, or makes you uncomfortable in any way.
Q:How can I regulate current from a solar panel?
If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
Q:highest known watt output for solar panels?
Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.
Q:Is there any way I can get solar panels with my restrictions?
There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.
Q:how to design a solar panel to store energy and convert it into electrical energy?
image voltaic panels do no longer shop capability, they basically generate it. in case you opt to shop capability you like a battery economic enterprise of a few sort to get you for the time of the night and each time the sunlight isn't shining. in case you have somewhat extra in the fee selection you would be able to desire to look at a geothermal equipment to your place's heating and cooling needs. they are distinctly useful structures and you'd be able to supplement notwithstanding you like. notwithstanding you do, in spite of the indisputable fact that i'm hoping you have a sturdy construction envelope in place already. image voltaic panels are cool, yet once you have a leaky homestead, you're nevertheless no longer getting the final out of your panels. Do the extra mundane stuff first. Insulation, homestead windows, and climate-tight doorways.
Q:are solar electric panels viable in the northwest?
Take You need to keep in mind that as long as you are renting your electric from the public utility you are doing just that and renting. You can resale the solar electric system if you move or if you just want to sale it and get some of your money back if not 20 % extra. Then all the years you used the system was all free electric. So it is already viable as you put it. Anything other then buying a system would not be. Here is a thought. The housing market slumped and if you paid 50K for your home it is now only worth if you can even sale it about 00K. Not worth the money but people are still buying homes even if they are not worth what they are being sold for. And then the cars and trucks people buy will never pay for them selfs but people still buy them and spend extra the more wasteful the car is. So why does solar have to pay for it's self or prove it's self? It has many times over but because you can't drive a solar panel drunk and party out in the bars with it is is not worth the money. I guess the is just being human and a double standard. What about the big up front cost of solar? I remember a 20% up front cost when I bought my home and my car and it is the same 20% or less for a solar loan. Plus the value of solar is going up not down like with homes and a car is not worth but half what you paid for it the minute you drive it off the car lot. I can only see good from solar un like other things we buy.
Q:Question about home solar panel systems?
As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.
Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
Q:Home solar electricity advice? Making the solar panels accessible?
Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
