Characteristics of Polycrystalline Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology. .

Q:Should the value of solar panels be included when appraising a home?
Zillow appraisal is useless and not at all important. If you are selling your home then the solar installation should give you some advantage, depending on how much you are still paying for utilities. The only appraisal that matters is the one a buyer gets to lock in a mortgage. Nothing else matters.
Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.
Q:How do you connect a solar panel to a motor from an RC car?

Q:How do you make a homemade solar panel?
you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself
Q:Are Solar Panels worth it in Southern California?
There are several factors to consider when looking into solar power for your house. If you want to replace your use of utility electricity with solar power for say a 500 - 2000 square foot home then the system will cost you at least $30000 - $50000 to install. You will also have the maintenance issue of your storage batteries, panels, and inverter which will eventually wear out over time. So lets say we have an optimistic price of $30000 for a whole house system (this would be really cheap), dividing this by your yearly consumption would give you the amount of years it would take for the expenditure to pay for itself (not counting maintenance which could be costly). The payoff would be about 25 years, so all things remaining equal, I would say that it is a bad investment. Solar panels as they are manufactured today do not have a very long life span. They will greatly decrease in efficiency after several years and will most likely need to be replaced in 0 years. The panels themselves are the greatest expense. You could problably find better ways to make/save more money by investing $30000 - $50000 somewhere else IMHO. Solar technology is still not at the point where it is profitable in the sense you are thinking about. Unless of course, there are huge tax incentives for you or large rebate programs through your local utility, but you would have to do the math on that as well. If you are thinking small as in a couple panels to supplement your utility electric, the above still applies as well. In fact will it take longer to recoup the cost of a smaller setup. Hope this helps!
Q:How long does it typically take for solar panels to pay for themselves?
Hi Warne, Payback period of solar panels depends on three main factors: ) Amount of solar radiation available: the more solar resource available at a site, the shorter the payback period will be. The insolation level is a function of latitude, cloudiness, elevation and some other factors. 2) Availability of grants, incentives and tax credits. Reducing the initial cash outlay is a great way to speed up profitability. For example, in the US, the 30% federal tax credit greatly reduces the payback period as it puts some of the cash back in your pocket in a short amount of time. Minimizing the initial cost has a big impact, since money in your pocket today is always worth more than money down the road. 3) Net metering or feed-in-tariff. If you are able to sell back your excess power, or all of the solar electricity to the grid, then you can also improve the payback period. Feed-in-tariffs are not very common in North America, but net metering is an option. Investing in energy efficiency measures (e.g., LED lights) at the same time as solar may help generate more excess power and help with the bottom line. There are some online calculators which may help you put all these together for a specific site. I'm including a link below.

Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
