- Q:Can cold light make solar panels power
- The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
- Q:ok so when a solar panel is marked as a certain wattage dose that mean it makes that much in a day in an hour or constant, dose it still work at night or what ? is it worth it or is it more of a pain? can some one tell me what all the watts and volts mean ?? and can some one tell me what a kilowhat is in refrence to some thing i understand like howmany loads of laundey can you do wt a watt? i need help understanding this stuff?
- Quick okorder .
- Q:I am looking to get some solar panels for my home to just power a few lights, a fan or two. I have a generator but I want that only to power the fridge and maybe some other small stuff for convenience.But mainly want the solar panels for the lights and fans. Any one have an idea of how about I go to figuring this all out? Should I call a contractor or anything?
- depends on what light bulbs you have in watts.depends on how many you want on. for the power equation you take P which equals watts x I which equals amps and E which equals volts and you multiply the amps and the volts together to get the watts which the solar panel is generating. for example if you had 7 60 watt light bulbs you would need 420 watts generated. which if you got 50 watt panels each you would need 9 panels. and for what your talking about if you want the stuff to work when the power goes out you are going to need an inverter. not to be confused with a grid ti inverter. and a few batteries i recommend deep cycle batteries that are meant for solar panels. depends on what fan you have.
- Q:What is a good sight that I could go to about installing solar panels and all of the considerations of it?
- I okorder / okorder /how-solar.html to see how the cost adds up for you.
- Q:Can solar panels be used in remote areas with no access to the grid?
- Yes, solar panels can be used in remote areas with no access to the grid. Solar panels generate electricity from sunlight, making them an ideal solution for off-grid locations where traditional power infrastructure is unavailable. They can be installed in remote areas to provide a reliable and sustainable source of energy, allowing for essential power needs such as lighting, charging devices, and running small appliances even in areas far from the grid.
- Q:I need to know how solar photovoltaic panels work. Anyone have a good explanation?
- Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
- Q:hey, Im going into my senior year at high school and after that will be moving to Pennsylvania where my family has a house on ten acres and I will be going to college there and living all year around. My father wants to build a huge barn for our cars and other stuff like tools, I mentioned too him what about solar panels on the roof to power maybe the house and barn. Would this be a good Idea? Where would be the best place to look into getting solar panels be? Thanks for anyones help!
- This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
- Q:How can solar panels be integrated into building designs?
- Solar panels can be integrated into building designs by incorporating them into the roof or facade of the building. This involves installing solar panels in a way that seamlessly blends with the architecture while maximizing exposure to sunlight. Additionally, solar panels can also be integrated into shading devices, windows, or canopies to generate electricity while providing additional functions such as shading or daylighting.
- Q:if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
