Q: I am confused. I am planning to build a simple 2Watt solar system to power some lights in my house. . I wonder if it is possible to power up a 2Watt bulb using 2Watt solar power?2. Normally, when we are reading the power rating of a bulb, we will read the wattage, so what about the voltage and current rating?3. If the current is insufficient, will the bulb light up?I am having a solar panel that can output 2W power but I am not sure about the output voltage, how can I find out about the current? I am getting really confused.
. Practically no. You have to account for startup current, and losses in the system. Ideally you would size your solar planel to provide the power you need to charge batteries in the day, for your needs at night. 2. Watts=Volts times Amps Really you just need to match the load and supply for volts, and make sure the supply has enough capacity to run your load. Current will take care of itself., in that the load will take what it needs to do its work. 3. It will bring the voltage down, causing the light to be dimmer.
Q: Can solar panels be used in combination with wind turbines?
Yes, solar panels can be used in combination with wind turbines. This combination of renewable energy sources allows for a more reliable and consistent power generation, as wind and sunlight are complementary in nature. By integrating solar panels and wind turbines, the system can generate electricity during both day and night, as well as in varying weather conditions, maximizing energy output and increasing overall efficiency.
Q: I want to get a solar panel to run a fan (or two) for swamp coolers.I'm not looking to power 20box fans, just maybe some of those auto fans.What the heck kind of panel do I need? What is a power inverter and what does it do?Will I lose all my power if I use a 00' extension cord?How do I choose what I'm going to need?
Any fan you find in a store is going to expect AC, not DC, which is what solar panels produce. An inverter changes DC to AC. You'll probably want a deep cycle car battery to smooth out overages and underages. Any fan will tell you how many watts it uses. Panels should (i haven't looked) tell you how many watts they produce. Just off hand, I'd guess you're looking at a 2'x4' panel. Considering how much you'll be paying for the rest of the stuff, a good 00' cord is appropriate,. Last, it's worth the experience, but you'll never recover the cost of everything that you'll have to buy. Have fun.
Q: Can solar panels be used in areas with high levels of snow or ice?
Yes, solar panels can be used in areas with high levels of snow or ice. However, the efficiency of solar panels may be reduced during these conditions. Regular maintenance and snow removal are necessary to ensure optimal performance. Additionally, tilted solar panel installation and using anti-reflective coatings can help minimize snow accumulation.
Q: I have heard you can make your own solar panels.... But How?Where do you start? Is it cheap, or should I just BUY them already made?
Well, I can think of a couple places, that you might have got that info from. There are several plans on the net. to build solar heaters from auxillary window units, to full thermal mass walls, with stacked 55 gallon barrels painted flat black, and filled with water. Old Mother Earth News magazines are a great source for these, but its basically sittin a closed box in the sun. . . Not very sexy, and not exactly Rocket Science, I'm thinkin what your askin about is Photovoltaics. Basically a reaction in a silicon chip, that pushes an electron toward the grid. Electiricty producing solar panels, are beyond the capabilities of a single person, however, they''re are (or were a couple months ago). a couple retail sales OKorder stores, scavaging they''re broken panels, cutting out the individual single cells, and then selling them as kits, with instructions how to wire, solder and assmeble working cells. Thats probably what your hearing about, and I think they ended up being about /2 price what they''re new ones sell for. Then you can move on to the bottlemeck problem, that all the green alternative ideas run into . . .How to store it Good luck, and Good Hunting . . Tim
Q: Can solar panels be installed on public transportation systems?
Yes, solar panels can be installed on public transportation systems. In fact, many cities around the world are increasingly integrating solar panels onto buses, trams, and trains to harness clean energy and reduce carbon emissions. These panels can be installed on the roofs or sides of vehicles, enabling them to generate electricity and contribute to the power needs of the transportation systems.
Q: I'm making a model of a solar photovoltaic tower for a school project. I need a way to store energy, and we thought about using capacitors (mainly because of our somewhat limited funding). The tower will have a small photovoltaic panel (around the size of a laptop keyboard with number pad) and some (around 50) quot;heliostats(just the mirrors, no moving parts). What kind of capacitors should i use? and would a capacitor bank be better? i am getting confused with all those uF, pF and can't see the difference.Thanx in advance
You need a rechargeable battery.Those uF you are talking about are Micro farads and pf are a million times smaller,they are less than gnat-bites compared to any rechargeable battery.You can get metal/metal hydride storage batteries (about .4v)and connect them in series if the voltage you generate is greater than that or in parallel if voltage is lower.Hard to advise without knowing voltage output from your design.As to getting hold of them there are so many in use you are sure to find someone who will lend a few (I would anyway!).
Q: Can solar panels be installed on historic buildings?
Yes, solar panels can be installed on historic buildings. However, it is important to consider the architectural integrity and preservation of the building. The installation should be done in a way that minimizes visual impact and preserves the historic character. Special considerations and regulations might apply depending on the building's status and location.
Q: Can solar panels be used to power an emergency response center?
Yes, solar panels can be used to power an emergency response center. Solar panels can generate electricity from sunlight, which can then be stored in batteries or directly used to power the center's equipment and infrastructure. This renewable energy source can provide a reliable and sustainable power supply, making an emergency response center less dependent on traditional energy sources during critical situations.
Q: i'm talking abt bulk panelling, how many MW do we get from km sq?
As okorder / They are working on a reactor that makes diesel and electricity concurrently out of coal, biomass or possibly garbage in a non-polluting process.
