product description



  • Base stations - for mobil and internet provider

  • Polycrystalline silicon, also called polysilicon or poly-Si, is a high purity, polycrystalline form ofsilicon, used as a raw material by the solar photovoltaic and electronics industry.

  • Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called Siemens process. This process involves distillation of volatile silicon compounds, and their decomposition into silicon at high temperatures. An emerging, alternative process of refinement uses a fluidized bed reactor. The photovoltaic industry also produces upgraded metallurgical-grade silicon (UMG-Si), using metallurgical instead of chemical purification processes.

  • Military and Paramilitary base stations

  • United Nations and other Humanitarian Aid & Relief Agencies

  • Mining Contractors (exploration/drilling)

  • Emergency Services (Natural Disaster Organisations)

  • Road, Bridge, Pipeline Construction Organisations

Q:What direction do solar panels usually point?
I can't believe how many people posted wrong answers to this. Where are they looking? What are they thinking? In the northern hemisphere, solar panels are ALWAYS oriented due south. In the southern hemisphere, face them due north. I am typing on a computer that is running on a solar electric system that supplies my whole house. Been this way for years. So it works.
Q:How much electricity does a solar panel generate?
This question was answered a few days ago. The Watt is the unit of of power, not the unit of energy. Energy is measured in Watt-Hours or Joules but not in Watts per unit time --- see the difference --- [] a Watt per hour v. [2] a Watt for an hour? The term, Watt per hour does not make any sense --- it is a bit like saying my car has 00 Horse Power per mile. You are right to say that the round figure for the power input of a solar panel is ,000 Watts per square metre, in the middle of the day when the sky is clear. Were the sun to shine for 0 hours per day in the summer, you could get as much as 7kWatt-Hours per day --- if you were very lucky. The roof area of a small house is no less then 50 square metres and this is more than big enough to supply all of you household energy needs but taking account of rainy days and taking account of the need to store the energy for night-time is an expensive problem, to satisfactorily overcome.
Q:Want to power this with solar panels?
You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of 4.5v@0.66A (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)
Q:where do you get little solar panels?
Thin-film solar panels are a great way to go if you're looking for small solar panels. Thin-film have the advantage of being lighter while a traditional crystalline panel is more efficient so it can produce more power with the same area. With the increasing efficiency of thin-film solar panels, however, they are quickly becoming an excellent option for portable power solutions. If you want crystalline panels instead of thin-film, the DURAlite line is a good example of a portable solar panel that uses regular polycrystalline solar cells. DURAlite panels come in 5, 0, or 20 Watts and they have a 0' cable with a 2-volt car-style socket plug.
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
The okorder.com) or the Tekkeon 3450 with the optional MagSafe connector (or the same Apple Airline cable as described for the Brunton). Set the output voltage to 9V and use the 2V cigarette socket outlet, and plug the airline adaptor cable in. Can you simply use an AC inverter? Not direct from the solar panel... a solar panel is not able to drive an inverter. But you could plug an AC inverter into a solar storage battery pack if it is designed to support inverters. BUT, an inverter will waste 20-30% of your power in the conversion to AC which your laptop will be converting back to DC anyway, so best to stick to DC and save your solar investment from the losses. Summary... 0 Watts of solar per hour of laptop use (May-Sep) 50 Watt-Hours of solar battery storage per hour of laptop use Use a solar battery pack with appropriate output voltages built-in, and avoid AC inverters. This is probably a longer answer than you were expecting, but knowledge is power. Cheers.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
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:Would you put solar panels on your home? and why?
I believe the best economy comes out when a completely green house is built. Solar panels are expensive, and I'll rather use some of the investments to build different back-up systems, instead of bying solar panels for it all. If I build another house, my fancy stuff would be the green stuff. The house will have a water radiator heating system and a heat pump to circulate warm or cold air in the house. Heat pump also used to heat water for heating system. I'll use solar panels to make enough electric power . charging a deep cycle battery pack for back up power, 2. to power heat pump, fridges., freezers, and water pumps, when I'm not home at the house. When I'm home I'll run a bio-fueled(bio-waste and pellets or firewood) powered steam engine with a 0KW 0-220V generator when I need electric stove and oven, dishwasher and laundry appliances. I'll use a wood stove, BBQ and oven on the porch for summer cooking. I'll use excessive heat from steam engine for heating water tank. I'll also have an bio-fueled (waste and pellets or firewood) water heater for winter heating back-up. Of course I'll make sure I'm connected to the electric grid, so I can get credit from power company for the excessive electricity that will occasionally come out from solar panels. Steam engine can be replaced by diesel powered 0KW generator, if it's possible to fuel it with veg-oil home made diesel fuel. Depends whats most accessible at my living site.
Q:I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
