Characteristics of 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.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:How powerful are solar panels?
if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.

Q:simple definition of how a solar panel works?
Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.

Q:Whats the annual energy output of the average solar panel.?
The energy output is highly dependent on the location. For a specific area, you can look up the equivalent peak sun hours per day here: rredc.nrel.gov/solar/old_data/nsr... Let's say that it says the peak sun is 5 hours / day in your location. Then a typical 200-watt panel would have 5 x 200 = 000 wH = .0 kWh per day, or 365 kWh annually. The tables above already take into account average cloudy days, and seasons. A typical size installation would have perhaps 6 of these panels, but it could be less, or much more.
Q:45 Watt Solar Panel Kit Harbor Freight?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
Q:How to tie small solar panel system into my house's electircal system?
Not that simple. The N E C covers electrical systems and your state utility regulators cover what and how you can do it. As a practical consideration the inverter produces power and would have an outlet to tap it. Possibly a standard convenience outlet that is the same as your house devices. The problem is to provide a cord that does NOT have exposed hot conductors when it is plugged in and how do you isolate the system from the power grid. To do this you need both a reverse service device and transfer switch that will isolate the house from the grid while the inverter is operating.
Q:how much money do solar panels cost?
In the US, the average electric cost $.5/kw-hr. $2500 means you are using 6700 Kw-hr/month or 550 kw-hr/day. Since solar panel only make peak kw for about 5 hours per day (in sunny places like (AZ) you will need a 0 kw system. Solar systems cost about $7/watt so your system will cost about $750,000. The government my pay for about $250,000, so be prepared to spend one half a million dollars. You will also spend about $250/month on maintenance of the system. The system will lose about %/year of it's efficiency, so the system will be paid for in 240 months, or 20 years. With in 5 years after the system is paid for, they will have to be replaced, the cost will be another 2 million dollars.
Q:Have a question about mobile homes and solar panels!!!?
I was in debt up to my eyeballs, and I needed help fast, so I looked to some free online programs. I had tried so many that were scams, but I finally found one legit one! In two months, I paid off $3000 of my debt.
