FAQ of Poly 230W Solar Panel CE/IEC/TUV/UL Certificate 

(1) Can you offer the test report of the module?

     Sure. All the solar modules must pass necessary tests including EL test and ultra-red test and other visual test of the apperance, and the test report presents all the detailed data of the modules.

(2) How  to confirm about the quantity and the type of solar module?

     It depends on the solar system where  you want to put into use the solar modules. We have experienced engineers to design for your order and you need to give more information to fix the details.

Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
First off, you should consider cost per kilowatt-hour (kWh) since kWh is energy whereas MW is power, and kWh is a common unit of energy used by power utilities. But first you would need to design the power capacity required, which as you state, is assumed to be MW. Average system costs = $95 per square foot Average solar panel output = 0.6 watts per square foot Average solar energy system costs = $8.95 per watt Form this information, the capital cost of installing MW = $8.95 /W * 0^6 W/MW = $9 million. The lifetime of a typical solar power system is probably about 20 years. Assuming a true MW peak output of the solar panel it would be anticipated that a daily average energy production would be peak output over about 3 hours per day, or 3 MWh of energy per day. Total production over a 20 year system life would be 3 MWh * 365 days/yr * 20 yr = 22 x 0^3 MWh So in terms of costs of capitalization of the system, the cost of Energy (/kWh) = $8.95 million / 22 x 0^3 MWh = $0.40 / kWh (approximately) This cost does not include maintenance, however, given the simplicity of these systems; other than periodic equipment replacement, which is covered by specifying a 20 year complete system replacement; other maintenance cost should be relatively low. The required surface area of solar panel = 0^6 W / 0.6 W/ft^2 = 94,340 ft^2 or a little over 2 acres of panel surface area. To be able to properly access and maintain the solar array, the minimum area required would likely be 5 to 0 acres.

Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q:how do buildings circulate energy?
The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
Q:How much power does a solar panel generate?
That site tells you somewhat about the cost of solar panels and their MAXIMUM output. Now some who have these panels claim output, in daily terms, 8 times as great as maximum output, which says they are counting on 8 hours of effective sunlight. In California Desert that is sound. You will discover that Ontario Power grid is planning for 3 hours to 4 hours of maximum output . Based on that 3 to 4 hours of maximum output, it would take close to 20 years to recover your cost at the price Ontario pays for solar power. The deal locks you in so that you can not get more money as electricity prices go up, and do not lose if electricity prices go down over that 20 years.
Q:when building a solar panel should the diode be on the positive or negative side?
Bypass diodes would be in parallel with groups of solar cells in a panel. For example, if a module has 72 cells, maybe every 8 cells, there will be a bypass diode. A bypass diode does nothing except salvage some of the energy from the panel if some of the cells are shaded, and others are not. Or, if you have multiple panels in a series string, the bypass diodes allow the other panels in a string to continue to contribute energy when one panel is shaded. Unless you're forced to put the panel(s) where there will be shade during the day, the bypass diode does not matter. Commercial panels all include bypass diodes. Blocking diodes are generally NOT included on commercial panels. If you're going to a grid-tied inverter, you probably don't need one. There are stringent regulations on how panels must be grounded, and whichever side of the panel is grounded should not have a blocking diode. NEC regulations call for a continuous ground to earth. For example, if you have negative ground on your system, the blocking diodes, if any, should go on the positive terminal of the panel. By the way, if you're in the US or Canada, do understand that a home-built panel will not be legal to connect to a grid-tied system. And a grid-tied inverter that plugs into the wall will also be illegal. I'm only saying this because I don't want you to get hurt, or your house to burn down. Line power is nothing to be trifled with.
Q:Solar Panel energy 500 KW monthly?
Replace your compression driven airconditioner with a gas fired absorption cycle air conditioner (there'll be a government subsidy or grant for that due to the R22 being phased out), install vacuum tube solar thermal collectors at a tenth the price of solar photovoltaics and use the hot water for the absorption cycle heat source with the natural gas burners as a backup. This avoids all the energy losses involved in the various energy conversions and solar thermal uses all wavelengths of solar energy while many photo-voltaics uses only one wavelength (newer dye based, multi layer, and quantum dot photovoltaics are all about using more than one wavelength of light). Solar thermal will also give you hot water and residential heating which are the other two big energy uses in a home. If you are bent on spending ten times the money on photovoltaics instead of solar thermal then figure out how many hours you actually run your AC for, use the filter replacement counter on your programmable thermostat to give you how long your fan is running in days and multiply that by 24 then divide your 500 kw/hrs by this value and since the power company only buys power from you at half the price that they will sell it to you at and you will have to buy power back at night, multiply by a fudge factor of say .5, this gives you a rough estimate of how many watts of solar panels you'll need to install in kilowatts, multiply this by 0,000 and that's roughly how much it will cost you in dollars (assuming $0 per watt installed, solar cells can be as low as $ per watt to manufacture but those aren't available yet and you also need to have them assembled into panels and installed so $0 per watt is a reasonable figure, people usually use values from $4 per watt through $9 per watt). Then after you get over the sticker shock, reconsider solar thermal.
Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
