SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

Q:what is one benifit in a solar panel?
what do you want to know ? there is so many benefit of the solar panel , such as no pollution , ETC
Q:Where is the best place to get an education/experience and job in the installation of solar panels? ?
The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.
Q:having problems with my homemade solar panel....?
5.3V is the open voltage or? So the full wattage of the photograph voltaic panel is 45W or so? i assume you are able to no longer make all your small A/C home equipment into DC ones. so which you would be able to think of bearing directly to the 2V DC enter 00W inverter. this type of inverter might have a some bit extensive enter voltage variety from like V-20V some situations.
Q:Solar Panels heat absorption?
solar panel just suit the sunshine.because it has big light intensity . it can make solar panel produce electric charger.
Q:Do you know that China is the largest producer of solar panels in the world?
I visit hundreds of houses a week in my line of work and there are houses in neighborhoods that aren't the wealthiest that have solar. It might be cheaper than you think.
Q:How many solar panels would I need to power my washer machine?
The solar panels have a 2 volt DC output.You would have to get an inverter and a small battery bank to run the washer.
Q:how to power a 400 watt heater with solar panels and batteries?
You could do that, but it would be an expensive way to go. If what you really want is heat, consider heating water directly with conventional solar water heaters, and storing it in a large, insulated tank. You can then circulate the water through a conventional radiator at night.
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:WHAT ARE THE SOLAR PANELS ON POWER POLES?
Here is an article about this. They use the poles (which they already have) and install power panels, the electricity is given into the grid. There are companies in NJ which use google earth to find buildings with large roof tops (imagine all the warehouses !), contact them and lease the rooftops to install solar panels, there a different ways how to finance that (by them, by the company, ....) and they sell the electricity into the grid and receive a certain price for this. Usually the refinancing is 5 - 7 years of the investment, after this is profit for additional 5 - 20 years. Walmart had a project to put solar panels on the super centers ....
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
