Q:How do you make a homemade solar panel?
you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself
Q:Solar Panel Manufacturing?
At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
Q:cheapest solar panels sold on line?

Q:How do solar panels and their battery backup systems work?
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
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:how to power a 400 watt heater with solar panels and batteries?
Get the rating from the manufacturer, they will give you the watts per m2 of their panels. divide 400 into the rating and will have the total area, then get the area of the panel that physically fits better the project and divide the total area into that of the panel selected, you will have how many panels you need. For the batteries is more complicated because of the available light hours of your location and what time of day are you going to use the heater, to be safe make a bank of batteries to store 600 watts to have a 50% stored power for emergency
Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
What is the open circuit voltage and voltage under load with the panel in full sun? Assuming it is typical of many 0W panels, the open circuit voltage is 2V and the voltage under load is about 7V. 0W/7V is 588mA. A typical car battery is 40 Amp Hours. Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah - would be maybe two days of full sunlight - with only a 50% charge, or about 2.2 Volts. Not a great battery charger - however - It makes a great supplement, and can offset the use of DC powered equipment in the vehicle while the engine is off. Things like low-wattage lights, cell phone chargers, tablets, and the like will drain the battery down that much slower. I have a number of powered but low current items on in my truck all the time. A panel helps offset some of that drain if I don't drive for a few days.
Q:how can you make your own solar cells for solar panels?
Found this video demonstrating the process of making home made solar cells. I do not think this method would be very practical for an off the grid home system.
Q:Why are solar panels made from silicon and not magnesium?
One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
Q:Powering my house with solar panels?
Homes vary tremendously in their usage. It will be a factor of 0: between a conservative house, and a heavy use one. To get the answer for your own house, check the electric bills. Also, the answer for the size of solar electric system varies with the location of the house. A Minnesota residence may get only 2/3 or /2 of what an ideal California house gets, even though both are sunny. As a data point, our California house has no air conditioning, no electric heat, no pool, and no big screen TV. We use maybe 5 - 8 kWh a day on average (more in winter, less in summer). We have a 3 kW solar array on the roof, and it roughly keeps up with our usage.
We introduced the newest production line, testing machine, laser cutting machine, non-Pb soldering line, module testing machine, laminating machine and so on. We use top-quality solar cells and EVA,TPT,strengthen glass,seal silicon etc. Our experienced staff work together well to assurance quality under effective ISO system. Our Products are exported to Europe, America, Africa and other Asian countries with safety certificate.
