Q:i want to join multiple solar panels into a bank so i only need one length of wire, i am going to use diodes to stop them sending power back into the one before it. is this ok or do i need something else?: It sounds like you intend to put them all in parallel, since you mention blocking diodes. If the panels are all roughly the same voltage, that should work. Mismatched panels will also work, but there may be little to no contribution from the lowest voltage ones if they are severely mismatched.

Q:Can solar panels be installed on train stations?: Yes, solar panels can be installed on train stations. In fact, many train stations around the world are adopting solar energy systems to power their operations and reduce their carbon footprint. Solar panels are installed on the roofs or canopies of train stations to harness sunlight and generate electricity, which can be used for lighting, heating, cooling, and other station facilities. This renewable energy source makes train stations more sustainable and helps in the transition towards a greener transportation system.

Q:How much sunlight is needed for solar panels to work?: Solar panels can work with any amount of sunlight, but they are most efficient when exposed to direct sunlight for at least 5-6 hours per day.

Q:If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?: Considering capital outlays, such a system might never recover its initial investment. That's why we don't see such small photovoltaic plants popping up around the country - the economic case isn't there. One of the problems is that you would have to sell your electricity wholesale, at a ridiculously low price like 2 cents / kWh. If you were displacing electricity that you would otherwise use, then the financial case is different. Retail electricity could be 20 cents / kWh, 0 times as much, and you could get your money back over time, and start to make a profit. I've assumed you're in the US, with no special feed-in tarrifs. If you're in a country with a premium rate for solar-generated electricity, the business case could be very different.

Q:I am currently building a house, iv designed it to be as self sustainable as possible, I'm in the process of installing solar panels but as I'm ordering online I was hoping someone here could tell me how many I would need to completely run a 5 bedroom home, just standard household appliances such as fridge and freezers, plasma tvs computers and of course lighting, various things like that, also I'll need power storage as well, some type of large rechargeable battery, any help would be great.: You're missing a few assumptions: - where on the globe? - how well is your house insulated, how do you plan to heat/cool your house? - why do you insist on power wasting appliances like plasma screens? Usually, unless it's absolutely impossible, a grid-tie-in system is much better than an insular system. You could use the grid to 'store' electricity for those times when the sun isn't shining and as fall-back if your yield isn't quite as good as you calculated. With the battery system, you'll have to specify your reliability requirements. If you want a 00% guarantee that you'll always have electricity, even if the sun is not shining for a week longer than you've planned according to the past weather history of your area, you'll either have to ridiculously oversize your battery (and panel) system, or plan for some sort of backup system anyway. Finally, if you're really planing such a system, you might want to take a look at the fridges and freezers used on sailboats: these use a eutectic cold accumulator, i.e. you 'charge' the fridge when the engine is running (or the sun is shining) and it'll then keep the temperature for another ~2...35 (professional systems) hours.

Q:I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV: I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.

Q:What in the solar panel wares out so that the panel can not convert the suns energy to electric energy? Please post were you get answers.: Panel degradation can occur in many ways, but they generally take a long time (40yr old panels are still working...). One problem is diffusion. Since the cells are at a finite temperature and receive energy from the light, atoms in the structure can migrate around the cell. If you mix up materials from either side of the junction, you can reduce or remove the internal field and so charge separation no longer occurs, meaning no more current output. This is generally a very, very slow process. My current research is on the back contacts of cadmium-telluride solar cells. CdTe forms a junction with metals, and this junction has a built in electric field that tries to stop the current going out of the cell. This is bad! It reduces the power you get out. To overcome this, copper is sometimes added. This really cuts down on the restrictions on current, but copper is very diffusive. Within weeks at room temperature it can jiggle its way along grain boundaries (the solar cells aren't one big crystal, but a load of small grains. Our lab makes ones about 0.006mm across). Whilst copper at the back contact is good because it cancels out the effect of the field there, once it gets to the cell junction it has a worse effect. It can act as a 'recombination centre' or 'shunting pathway' - it either absorbs the free charges or takes them somewhere useless and cuts the power output. Copper is a very obvious and quick acting cause of solar panels reducing in output. I believe a similar effect is true for other cells, just with different materials. The quality of the junction degrades slowly as heat and light give energy to atoms in the lattice and make them jiggle around a bit. Once you have things out of place, performance degrades.

Q:I am told there are night vision goggles to see at night due to invisible light still hitting earth. I am also told that there are other beams, x-rays etc hitting earth.Why couldn't they invent a solar panel with dual power in the day?It could harness both visible and invisible light, and at night be single?Anyone know why they can't make an invisible light solar panel?Is this possible?What happens if future cars have night vision windshields instead of lights?: Build okorder /

Q:Can solar panels be used for powering a manufacturing facility?: Yes, solar panels can be used to power a manufacturing facility. By harnessing the energy from the sun, solar panels can generate electricity that can be used to run various operations in a manufacturing facility, such as powering machinery, lighting, and other equipment. This can help reduce reliance on conventional electricity sources, lower operating costs, and contribute to a more sustainable and environmentally friendly business model.

Q:Mitsubishi Solar Panels For Home Installation: How Much Do The Panels Cost?: Panels will cost in the range of 300-600 dollars for about 00 watts on average ( enough for one large lightbulb to run a few hours a day). The rest of the system needed will cost $2500-$4000. That is for the equipment. Cost for Installation?? Figure about 0 year life on equipment. It will probably never pay back investment, but will cut power usage. You can reduce power usage much more cost effectively buy simply conserving (Hot water temp. down, CFE bulbs, Better insulation, Better windows, Heat/Air a little colder/hotter, Attic ventilation, Geo Thermal heating/colling system). All of these measures will pay back sooner and save power usage. Solar will never pay back without major subsidies from the taxpayers. Particularly if in an area that has many cloudy days. Check it out. The calculations are basic and the facts are available if you really want them. Don't believe any salesmen or Environmentalists. They don't want you to know the facts.
