does vibration affect solar panels?
- probably not much. If you had it at an optimal angle to the sun and it vibrated out of that position then you could be loosing some efficiency.s
Where are the best places to put solar panels?
- The best place is where they get the most sunshine. Naturally they will be exposed to rain and snow.s
Does making solar panels cause more pollution than they take away when used?
- A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.s
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?
- Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.s
Solar panel question
- The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.s
Solar panels don't work when it's too hot/sunny?
- So what do higher temperatures do to solar photovoltaic panels? As temperatures rise, the efficiency of solar panels decreases. Heat causes electrical resistance to the flow of electrons. On days where the temperature is more than 75 degrees, the electrical resistance makes the voltage fall thereby producing less kilowatts per hour. Your roof is much hotter than temperatures on the ground. That’s why solar panels are not mounted flat to a roof. There’s usually a few inches of spaces between the panels and roof so air flow can easily pass through and cool the panels down. There are some photovoltaic panels that are designed specifically to operate in hotter temperatures. These panels have a higher temperature coefficient. This is especially important in high heat climates like Arizona or New Mexico, but probably wouldn’t make too much of a difference in New England (except maybe this year). If you do live in one of these areas, you should speak to your solar installer to make sure they are using they right equipment for your region. Please note: Solar thermal panels used to heat water can withstand high temperatures without any degradation. In fact, hotter temperatures would actually be better for these types of modules.s

can a l.e.d light power a solar panel?
- While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .s
