Q:Can solar panels be used for powering a mining operation?: Yes, solar panels can be used to power a mining operation. Solar energy can be harnessed to generate electricity, which can then be used to power various mining equipment and processes. However, the feasibility of utilizing solar panels for a mining operation depends on factors such as the size of the operation, energy requirements, sunlight availability, and cost considerations.

Q:If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?: For safety purposes and liability, I do suggest that you should hire a professional solar panel installer. The solar panels has a lot of engineered like work, So better hire someone who has a fully aware for this work.

Q:I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!: Solar okorder in their survival discussion in the archive, this exact project was discussed at length.

Q:How do solar panels affect the overall carbon footprint of a building?: Solar panels can significantly reduce the overall carbon footprint of a building. By harnessing the power of the sun to generate electricity, solar panels reduce the reliance on fossil fuels for energy production. This means that less greenhouse gases, such as carbon dioxide, are released into the atmosphere during the building's operation. Consequently, solar panels contribute to a cleaner and more sustainable energy system, helping to mitigate climate change and reduce the building's environmental impact.

Q:my solar panel is 5v 50 mA, and im making iphone USB charger so i need to connect + with 00 ohm resister and to data - and + so what resister will be okay..?: Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.

Q:Can solar panels be installed on a stadium or sports arena?: Yes, solar panels can be installed on a stadium or sports arena. Many stadiums and sports arenas around the world have already installed solar panels to generate renewable energy. The large roof spaces and ample sunlight exposure make them ideal locations for harnessing solar power.

Q:Where can I buy solar panels other than online in Charlotte, NC?: theres a sparkling technology of solor voltaic cellular popping out in 2009 which will diliver 40% greater potential than the regular living house use cellular panels, they'd cost as much as they do on the instant purchase at 40% greater its properly actual worth the wait, plus the advancements being made in case you do diside to make investments they are going to be obsolite in 5-0 years yet by potential of then the device could have paid for them selves, which in time they do. and in case you get a slow wind, like we do right here in northen indiana, get a wind turbine rated at 7k in line with day

Q:How much does it cost to replace a solar panel?: The cost of replacing a solar panel can vary depending on several factors such as the size, type, and quality of the panel, as well as any additional installation or labor costs. On average, the cost can range from a few hundred dollars for a small residential panel to several thousand dollars for a larger commercial panel. It is always best to consult with a solar panel installer or supplier to get an accurate estimate based on your specific needs and requirements.

Q:Im doing a science project and I need to know what gases or liquids a solar panel can make that is not friendly to the environment. Please name all the gases and liquids and explain how they damage the environment. It would be most likely that you will get best answer if you find all the bad things about solar energy and explain why they are bad and how they affect nature. that would be helpful to. Thank you: i think that there should not be gases produced from solar panel,that we use.

Q:I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!: First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
