FAQ:

1What price for each watt?

It depends on the quantity, delivery date and payment terms.

2What is your size for each module? Can you tell me the Parameter of your module?

We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.

3Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

4Do you have the CE, TUV, UL Certification?

We’ve already passed all the tests, and any certificate is available.

Q:How many solar panels do you need to power a house?
Here in southwestern Arizona more and more solar panels are getting installed everyday. If it wasn't an economical thing to do I doubt if people would be doing it. Given that because of climate change our summers are getting longer and apparently hotter running an air conditioner gets evermore expensive. Also every year or so the rates go up. At the current rate of increase rates will easily double in a decade. Installing a solar array means that in far less than a decade, given a hefty down payment, any government subsidies and tax breaks in a couple of years you'll own your own electric company. Technically about /4 of the US would benefit from a true government program to install solar panels on all buildings. Years ago it became law that every building had to have electricity, running water and flush toilets. We need a similar law to hurry up a conversion to solar where practical.
Q:How do Solar Panels Work?
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity.
Q:Does a solar panel work on a cloudy day or a rainy day?
A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
Q:Mitsubishi Solar Panels For Home Installation: How Much Do The Panels Cost?
Mitsubishi solar panels are sold in pairs. I was in the market this week, checking on solar panels to install in my own house / workshop. Here's the price list I got from online and wholesale dealers for a pair of Mitsubishi panels: * Model MF20EC4 (20 watts) -- $590 * Model MF25UE5N (25 watts) -- $60 * Model MF75MF5 (75 watts) -- $799 * Model MF80UD4 (80 watts) -- $820 * Model MF85UD5 (85 watts) -- $850 BP Solar, PowerUp Solar GE Solar too have their own panels with a low-to-high price range. Go for BP solar panels as they're more affordable for home installation and good value for money.
Q:Need some Information about solar panels ?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q:How does a solar panel charge controller work for batteries?
In digital circuitry almst anything is viable. Virtually. The changing of voltages and currents is most of the time viable however not constantly effective. Sure it is extremely easy to make use of the 24 volt energy panel to charge a 2V financial institution, offered that the 24 volt supply has the fundamental current potential to hande the load.
Q:how do solar panels work?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths. An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications. Solar-thermal panels saw widespread use in Florida and California until the 920's when tank-type water heaters replaced them. A thriving manufacturing business died seemingly overnight. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high. Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.

Q:Charge Laptop with Solar Panel?
humm..... .need HUGE solar panel (alot) 2. wires 3. aligato clips . put the panels on the roof 2. use the aligator clip to clip the wire from the panel to the bars of the pluger of the comp. charger 3.tada mark me best:)
Q:Help with Solar Panels?
If okorder.com/ for the solar panel design, Do it yourself DIY cheap and best guides which you can download right away. Using all the information, it will cost you less than $200 for building and complete installation of the solar panel in your house. This will cut your energy costs by atleast 50%. Many people are feeding the grid from the extra power they generate from renewable sources of energy like wind turbines and solar panels at home. So Good Luck!
