Q:What do i need to use a 2v solar panel to charge a 6v lead acid battery as i cant find a 2v to 6v regulator?
despite the statements to the contrary, using a solar panel to charge a battery is not rocket science. first lets look at you panel. panels normally have a spec for open circuit voltage (probably 20 volts for yours) operating power (4.4 volts at .4 amps is usual for 20 watt panel) and short circuit current (probably 2 amps in your case). if this panel is connected to a 2 volt battery, it will develop 20 watts of charge current in full sun. if this panel is connected to a 6 volt battery, it will work closer to the short circuit current or about .8 amps. doing the math this is a 7.2v x ,8= 3 watt charger for 6 volt batteries. while it is less efficient than when working at 2 volts, it will still work pretty good and no regulator is needed if you remember to disconnect the panel after 5 hours of full sun. if you want to walk away and have it run automatically, then you will need to find a 6 volt charge controller.
Q:What does solar panel power?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:2- 390 W Solar Panel's Series or Parallel?
Q:Need Solar Panel Guru.....?
I'm inferring that your goal is to save money. You're on the right track with your energy star appliances - saving energy is far better than installing solar panels to cover energy that will be wasted. You may have an opportunity with solar hot water - you would need a large storage tank with 3 people, but that would be the best use of your roof in my opinion. Check with a professional installer, it may make financial sense. Although you could make your own heating panels, it's hard to make a solution as durable as commercial panels. And if freezing is an issue in your area, you would have to drain a homemade system in the winter. With an evacuated tube commercial system, you could keep running right through the winter. In the summer, instead of running those expensive air conditioners, could you just have a cool room in the basement? Anyone who wanted privacy could still go to their regular room and run fans. We have no A/C in our house, and manage, even on those 00+ days. Sounds like awnings or other window coverings might be a big help for you, at least until you can get some deciduous trees in to shade the house in summer. I would advise against making your own solar electric panels. They would not save money over the long term. And check panel prices - they have dropped 50% this year, according to a recent Newsweek article.
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
Q:Please explain KW Solar Panels. What does it mean.?
It means that it will produce (at best) 5kW when the sun is shining in an ideal position, in hour that's 5kWh so, on a good summer day it may produce a total of 25kWh nothing at night see the link for a 5kW system, you need at least 0 possibly 20 times that.
Q:how to make your own solar panel?
try adding more solar panels to your car, what if you take the solar panels out of 2 or 3 calulators , add them, then use some tiny mirrors to help draw more light into the panels,.--------------------------------... solar cell (or a photovoltaic cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes the capacity to capture both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics. Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement. Solar cells are regarded as one of the key technologies towards a sustainable energy supply.
Q:What specification of solar panel do I need?
Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
Q:What type of wires should i use for a solar panel?
You might want to be careful about soldering. Some panels can be easily damaged by excess heat. Check the manufactures website for recommended attachment methods. Solder tape or conductive epoxy might be better. If you do not have such things already, a good idea might be to take it into a TV repair shop or electronic hobbyist store. Some folks are kind enough to do it for you for free.
Q:solar panels and calculations?
The okorder.com The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
