Q:Can solar panels be used in areas with high pollution levels?

Yes, solar panels can be used in areas with high pollution levels. While pollution levels may slightly reduce the efficiency of solar panels due to decreased sunlight reaching the panels, they can still generate electricity. Additionally, solar panels can help mitigate pollution by providing clean and renewable energy, reducing reliance on fossil fuels and contributing to a cleaner environment.

Q:How do solar panels affect the property's energy management strategy?

Solar panels can significantly impact a property's energy management strategy by providing renewable and clean energy. By harnessing the power of the sun, solar panels can reduce dependency on traditional energy sources, lower electricity costs, and promote sustainability. The excess energy generated by solar panels can be stored or sold back to the grid, further optimizing energy management. Additionally, solar panels can enhance a property's overall value and reputation, making it more attractive to environmentally conscious consumers.

Q:I know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.

If you are at a location/time where the panel will put out less power, you can adjust the battery size accordingly. And running a battery to empty is very bad for it's service life, so it's better to go a bit bigger.

Q:How many solar panels would it take to run an electric motor the needs 480 volts and pulls about 45 to 50 amps?

Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.

Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port, can i just tie the wires together and run into the controller?? Will damage anything...Thanks guys

Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo

Q:Can solar panels be installed on churches or religious buildings?

Yes, solar panels can certainly be installed on churches or religious buildings. In fact, many religious institutions have embraced solar energy as a way to reduce their carbon footprint and demonstrate their commitment to environmental stewardship. Installing solar panels on churches not only helps to generate clean, renewable energy but can also serve as an educational example for the community.

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:Please tell me what they are made of and how the materials help the solar cell produce electricity. Im doing a science projects so i need help on knowing all this info. Its a debate, so i need correct information please.I will please need more information about the bad things about solar energy and solar panels. Please say what solar panels do to create pollution or do anything that is not friendly to the environment. If you want just give me a website. Thank you

A okorder /, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.

Q:Can solar panels be installed on community buildings?

Yes, solar panels can be installed on community buildings. In fact, community buildings like schools, libraries, and community centers are excellent candidates for solar panel installations as they often have large roofs or open spaces that can accommodate solar arrays. Installing solar panels on community buildings not only helps reduce electricity costs but also promotes sustainability and clean energy in the community.

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.
