- Q:Are solar panels suitable for residential use?
- Yes, solar panels are highly suitable for residential use. They provide a clean and renewable energy source, reduce electricity bills, and help homeowners become more self-sufficient in terms of energy. Additionally, advancements in technology have made solar panels more efficient and cost-effective, making them an increasingly popular choice for residential properties.
- Q:Can solar panels be installed on swimming pool covers?
- Yes, solar panels can be installed on swimming pool covers. In fact, it is a popular choice for pool owners who want to harness solar energy to heat their pools while also conserving energy.
- Q:I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.
- Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
- Q:Can solar panels be installed on bridges or highways?
- Yes, solar panels can be installed on bridges or highways. This is known as solar roadways or solar bridges. These panels can generate electricity by harnessing sunlight and can be integrated into the surface of bridges or highways. However, the feasibility and practicality of such installations may vary depending on factors like structural considerations, cost, maintenance, and local regulations.
- Q:How do solar panels affect the appearance of a home or building?
- Solar panels can have a positive impact on the appearance of a home or building. While they do add an additional element to the exterior, the sleek and modern design of most solar panels can enhance the aesthetic appeal. Additionally, the presence of solar panels conveys a sense of environmental responsibility, making the property more attractive to eco-conscious individuals.
- Q:i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?
- Long ago, say, in the 960's, it was true that solar cells did not return the energy of their manufacture. In those days, cells were 4% efficient, and made with more material and a less efficient process. Unfortunately, the myth persists that this is still the case today from unaccredited sources. Kudos to Michael for the nrel link. That study was actually done over 0 years ago, and since then, technology has advanced even further. Manufacturers have been able to reduce the thickness of cells in general in the last decade, to use less crystalline silicon. Also manufacturers such as Suntech with their pluto process are now able to use a lower grade of silicon, that takes less energy to refine. The result is that the energy payback time is even shorter today than estimated in the linked paper.
- Q:Can solar panels be used in commercial buildings?
- Yes, solar panels can definitely be used in commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops or in open spaces adjacent to their premises. Solar panels are a sustainable and cost-effective solution for generating renewable energy, reducing electricity bills, and lowering carbon footprints in commercial settings.
- Q:i attached a usb charger to my solar panel(it has an output of about .2 volts) but i read on my multimeter its only using about 8 volts however on the conventional wall charger that i use to charge it has an output of about 5. volts.... i believe that my mp3 player is not charging it does not display the charging icon when it is on or off ....is this becuase the output is higher ? do i need to install a volt dropping diode to prevent it from putting to much energy at once? (my mp3 charges fine on the wall charger but does not seem to respond to the solar panel so it the circuits are fine....)
- 5.3V is the open voltage or? So the full wattage of the photograph voltaic panel is 45W or so? i assume you are able to no longer make all your small A/C home equipment into DC ones. so which you would be able to think of bearing directly to the 2V DC enter 00W inverter. this type of inverter might have a some bit extensive enter voltage variety from like V-20V some situations.
- Q:Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
- If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
- Q:I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.
- I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.
