Product Description:

20W CNBM Monocrystalline Silicon Panel for Home Using

Production description

 high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft, as they offer the highest ratio of generated power per kilogram lifted into space. MJ-cells are compound semiconductors and made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging PV technology using MJ-cells is concentrator photovoltaics (CPV).

Q:Do you know that China is the largest producer of solar panels in the world?
I know for a fact that -China has a lot of Nuclear Bombs pointing at the US--- paid for by Wal-Mart
Q:Solar Panel load resistors?
Solar Panel Load
Q:Do solar panels plug into an outlet?
They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.
Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q:Solar panel cable setup?
on the controller, it writes which would be related with image voltaic panel which would be related with battery which would be related with load all of it write on the image voltaic controller. only see the controller
Q:45 Watt Solar Panel Kit Harbor Freight?
I don't have direct experience with the Harbor Freight panels, but have heard that they are agressively rated - i.e., the three 5-watt panels are really 5-watt panels. The 80-watt panel is likely to be a serious panel, rated according to standard test conditions. It will also be more durable, and probably have a warranty of 20 years or more. There's really no comparison. If your goal is to experiment with solar electricity, then get the kit from Harbor Freight (or Northern Tool, or any of a handful of other places). If your goal is to save money, generally you will need a larger scale than 80 watts - several thousand watts being the norm. And the payback time will be measured in years.
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:how would you build a solar panel?
As a sandwich. Glass Space /4 inch Glass Space with copper radiator painted flat black. Box made of wood. with the inside painted black. Insulate the back side. Use water with RV antifreese. Circulate water through with a small pump. Face it toward the sun. Thermal water solar Panel.
Q:Questions about charging batteries via solar panel...?
A solar panel to charge a 2V battery has 36 cells in series. This allows for temperature of the panel up to 60°C, and the maximum required charge voltage. For a 24V battery, 2 panels in series. A 24V battery requires around 28-29V, but look up your battery data sheet to be certain. A specialized converter using electronics could charge a 24V battery with a 2V panel. The system voltage is controlled by the battery unless the battery is faulty. The 2 panels in series could be 42 volts no load, but the battery pulls this down to whatever is required by the battery. This is because the panels are a current source, the current is determined by illumination, and attempts to draw more result in reduced voltage. Even a short circuited panel delivers approx. the same current with no voltage. The battery voltage varies from around 20V (really flat) to around 28V (really charged). A 30W panel is around .75A, considering the optimum panel voltage for power is around 7V for 36 cells. This is small compared with what you are using. The battery wastes about 30% of the power, in chemical conversions. The time to charge it is 4h at the 0h rate, which is Ah/0. (i.e. ampere hours)
Q:What type of gases and toxics do solar panels use or produce?
i think that there should not be gases produced from solar panel,that we use.
