Q:Can solar panels be used in space?: Yes, solar panels can be used in space. In fact, they are extensively used in space missions to power satellites, space stations, and spacecraft. The absence of atmospheric interference allows solar panels to capture sunlight more efficiently in space, making them an ideal source of renewable energy for space exploration.

Q:What are solar panels?: Solar panels are a collection of photovoltaic cells, that are used to generate electricity, from light. Here is the simple explanation from wikipedia, concerning photovoltaic cells . Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. 2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel. 3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity. Solar panels are used extensively for power generation in many places, but most space applications (like satellites and spacecraft) use solar panels. If you look at a picture of the current configuration of the International Space Station, the giant wing things are the solar panels.

Q:Can solar panels work during cloudy or rainy days?: Yes, solar panels can still work during cloudy or rainy days, but their efficiency is significantly reduced. Solar panels generate electricity by converting sunlight into usable energy, so the amount of energy produced is directly related to the amount of sunlight available. Cloudy or rainy weather reduces the intensity of sunlight reaching the panels, resulting in a lower electricity output. However, solar panels can still generate some power even in these conditions, making them a viable source of renewable energy even on less sunny days.

Q:Why does the new 200 Toyota Prius have solar panels at the top of the vehicle?: Hi, the solar powered-venting system is not air conditioning, it is simply a venting system to attempt to balance the interior temperature of the Prius with the outside temp when the interior of the Prius is at least 68 degrees. This is an optional system and is available as a stand-alone option for $800.00 or $3600.00 in conjunction with the navigation system. The solar roof is integrated into a full function sunroof, but the sunroof can be opened without using the solar venting portion. There is a separate portion of the system that will allow the driver to turn on the electric AC for three minutes, if there is enough stored charge in the nickel metal hydride (NiMH) hybrid battery. The AC is not linked to the lead acid battery, and is run by the NiMH only, not the gas engine. The NiMH and lead acid are two separate power systems. The solar panels do not power anything else in the Prius and do not boost the power to any of the systems. The solar venting does permit less energy from the NiMH to be utilized for AC at the next startup. For trivia, the EPA will not allow Toyota to install the solar venting system on Prius with the top package V (#5). The EPA feels the Prius is too top heavy with all the additional sensors required for the radar guided cruise control and all the other high tech components in the top end option package, just FYI.

Q:Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q:How much would solar panels cost for: A Cell phoneA average houseA car: in case you recognize the place to look you get get image voltaic panels for 0 expenses. as an occasion, numerous sign companies use image voltaic panels. touch your interior sight sign company and tell them you will haul off all their broken image voltaic panel for loose. they're oftentimes extra beneficial than keen to assist you are trying this.

Q:Can solar panels be installed on churches or religious institutions?: Yes, solar panels can be installed on churches or religious institutions. In fact, many religious institutions are embracing renewable energy and installing solar panels on their roofs as a way to reduce their carbon footprint and contribute to a more sustainable future. Installing solar panels on churches not only helps them save money on energy bills but also sets an example for their congregations and communities by promoting clean and renewable energy sources.

Q:Can solar panels be used in conjunction with energy-efficient appliances?: Yes, solar panels can be used in conjunction with energy-efficient appliances. In fact, coupling solar panels with energy-efficient appliances can maximize the benefits of renewable energy by reducing overall energy consumption and dependence on the grid. This combination allows for a more sustainable and cost-effective approach to powering our homes and businesses.

Q:I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.: 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.

Q:I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?: You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?
