- Q:Can solar panels be used to power a space station?
- Yes, solar panels can be used to power a space station. In fact, many space stations, including the International Space Station (ISS), utilize solar panels as their primary source of electrical power. These panels convert sunlight into electricity, providing a sustainable and renewable energy source for the space station's various systems and experiments.
- Q:I have a college project due within a week, and it involves a 00 Watt solar panel and a 2V 7.5Ah Battery. I got the project finished up and producing free energy for my house in September, however recently the battery I bought, that was specifically made to hold Solar Power, lost its charge (unsure how or why) and it is pretty much useless. Can I just go to a store and buy any 2V car battery to use?
- A 2 volt battery is a 2 volt battery. Some are larger than others. Sure you can charge a car battery with a solar panel, but 00 watts for a long time could be a problem. There's one way to find out.
- Q:what are solar panels?

- Q:I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
- Q:could any tell me what type off panel is the best tube or flat and how much it should be. I live in N Ireland
- My solar thermal installation uses a 30-tube NAVITRON panel. This has an effective area of 2m2 and produces enough hot water in summer for 3 showers and plenty of washing up! I estimate that, in it's first year, it has saved me about ?60 in gas. The panels and prices are shown in the attached link. Mine was fitted by a professional installer for ?2500, including a huge, new cylinder (dual coil) to store the extra hot water. Flat panels are much less efficient than vacuum tube collectors. While flat panels are frequently cheaper, these Navitron panels are such good value that I think buying inferior, flat panels would be a false economy.
- 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?

- Q:Can solar panels be used in commercial buildings?
- Yes, solar panels can be used in commercial buildings. Many businesses and organizations are incorporating solar panels into their buildings to reduce energy costs, decrease their carbon footprint, and take advantage of potential tax incentives or subsidies. Commercial buildings have ample roof space to accommodate solar panels, and with advancements in technology, solar panels can be integrated seamlessly into the building's design.
- Q:For my exam in science we are required to make a power point explaining why it would be good for our school to switch to solar. our complete handout given to us by our teacher is as follows:Power Point to include:. What you propose for alternative energy usea. Any thoughts on energy conservation...2. Why this is a good idea3. What information you would give the solar company (area of roof space your group determined to be useable for solar)In PowerPoint - include your quot;scriptof what you would be saying when the slide is up in the Notes section below the slideANY HELP WOULD BE GREATLY APPRICIATED!!THANK YOU SO SO MUCH,QH
- Refuse to do the work on the grounds that it is not good for your school to switch. If the teacher tries to give you an F, escalate the problem to the principle and then the local news agency. Teachers are not allowed to force brainwashing.
- Q:Can solar panels be used for powering a water treatment plant?
- Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed to generate electricity, which can then be used to power the various processes involved in treating and purifying water. This renewable energy source provides a sustainable and environmentally friendly solution for powering water treatment plants.
- Q:I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
