Q:How Much Do BP Solar Panels Cost In The Wholesale US Market?
Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
Q:Solar Panel - Battery Charger 2V?
If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
Q:what are the parts of a solar panel?
A solar panel is just a collection of solar cells all wired up in parallel and series to provide a useful voltage. Typical solar cells only provide half a volt, maybe less, so usually you put 2 of them together to get a 6v solar panel or 24 of them to get a 2v panel. Solar cells are made in various ways, the most popular are silicon solar cells which are made with a chunk of silicon with a P-N junction in the middle and contacts on either side. When a photon of light comes in, the energy of the photon is converted to electrical energy. Individually, photons contain a tiny amount of energy, but when you have a solar cell in the sunlight, billions and billions of photons hitting it constantly create a useful amount of electrical energy. Solar panels are incredibly simple!
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:Anyone here have residential solar panels?
whether you advise water heating or electrical energy, i could advise contacting a expert installer, who will provide a quote, and generally has a variety or 2 of panel that they choose. image voltaic electric powered can save money, however the form of gadget that usually does isn't an effortless self-installation. yet to respond to immediately, i could make particular the panels are crystalline (monocrystalline or polycrystalline) silicon, and make particular they have a 25-2 months guarantee. it is enormously plenty everyday between all significant manufacturers. After that, i could circulate by potential of cost according to watt on my own.
Q:Why don't we use solar panels?
It's expensive - solar power isn't competitive with power from the grid in most countries and it's a very expensive in terms of capital - you have to put most of the money up front. Meanwhile fossil fuel plants are cheaper to build and from then on you only spend money on fuel when you're selling power (and of course you don't have to pay for the damage you cause society with air pollution and greenhouse gases).
Q:Solar panels for car fans?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
Q:How to select solar panel for this application?
Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
Q:What kind of Solar Power panel setup do I need for this?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
Q:Why don't we design a wind-turbine with solar-panels on it?
Good to know someone is thinking and coming up with original ideas, so thanks for contributing... Put a large powerful solar collector on the end of the turbine too i.e. facing the sky! Far as I know, solar works on day-light (doesn't have to face the sun). So your idea is not to be put down. Metal blade turbines - are heavy - wooden windmills - heavy... so some added weight to the wind-turbine's paddles would be OK robably. Great if solar device not made of glass (so unbreakable). I think panels on the roof are old hat...
