Q: How do solar panels impact air pollution?
Solar panels have a positive impact on air pollution as they generate electricity without producing harmful emissions. By reducing the reliance on fossil fuels, solar panels help to decrease air pollution and improve air quality, contributing to a cleaner and healthier environment.
Q: Can solar panels be installed on convention centers or event venues?
Yes, solar panels can be installed on convention centers or event venues. In fact, many convention centers and event venues have already started adopting solar energy systems to reduce their environmental impact and save on energy costs. The large rooftop spaces available in these venues provide ample opportunity for installing solar panels and generating clean, renewable electricity.
Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
Stephen is sweet in you should adventure the enter criteria of your inverter. so that you'll want to cord a minimum of a few cells in series. probable you should custom-go with a blend of series and parallel for the cells. operating example, if maximum of your fragments grant a million amp, then you actual ought to objective a million amp for the array. If there's a fragment that's 0.7 amp, and yet another that's 0.3 amp, you should parallel those, and count number them as one cellular, that you'll then series with the others. I observed this performed on one individual's panel years and years in the past. It gave the impression of an poor mess, and extremely some artwork, because the cells couldn't be in neat rows, anymore. also, if plausible, you should want the utmost equipment voltage you should use, because meaning decrease amperage for an same potential, and to that end smaller cord. 8 amps, after derating, skill #2 or #4 cord, an same variety that must be used to cord your position. 5 amps skill #0 or #8, and one hundred amps skill a fat cord like the jumper cables for a vehicle. in basic terms so that you comprehend, i trust that's typically unlawful contained in the U. S. to connect a selfmade array to a grid-tied equipment, or to apply a grid-tied inverter that plugs into the wall socket, in case you care.
Q: How do solar panels convert sunlight into electricity?
Solar panels convert sunlight into electricity through the photovoltaic effect. When sunlight hits the solar panels, it interacts with the semiconductor material, usually made of silicon, which causes the electrons to be excited and flow freely. This flow of electrons generates an electric current, which can be harnessed and used as electricity.
Q: Is it possible for a 2V rated panel to charge a bank of batteries equal to around 36V? I believe that the panels should equal or exceed the voltage of the batteries but, I'm not for certain.
With a 2 volt power source (solar panel, battery charger, vehicle charging system, etc...) you can charge three 2 volt batteries in parallel circuits then switch to a series circuit through a series/parallel switch to get 36 volts output. I've done this with my electric scooter so I can charge it with my pickup through the lighter socket when I'm away from home. It works great! When at home I just leave the switch in the 36 volt position, plug the charger in the wall receptacle and the charger puts out 36 volts. Actually 2 volt lead acid batteries have 2.6 volts when fully charged so the charging source has an output of 3.6 to 4.2 volts to effect a complete charge. In the series circuit the fully charged batteries would put out 37.8 volts so the charger would have an output of 40.8 to 42.6 volts.
Q: Hi,I am thinking about getting solar panels installed. # I like to cut my electric bill. #2 I like to eliminate my oil boiler and use some sort of electric boiler.I use about 5000-30000 KW per hour( winter-summer). My oil bill is around 600 month winter time. Over all i pay around 4000 a year. My electric bil now is around 2000-2500 year. Is this possible? I live in NY. I heard you can get up to $35000 rebate from LIPA( Electric company) and 2k from federal and 5k from State( is the state or federal every year?, how does that work). Any help is appreciated.
There is a variety of information available on the internet regarding solar panels. You didn't say if you were interested in installing a photo-voltaic system to generate electricity, or if you wanted a passive solar system. From what I've read, the method that would give you the greatest payback for your investment is the passive solar heater. I can't give you exact instructions on how to construct one of these units, but there are many websites with instructions. My older brother had one of these mounted on his old farmhouse. He said his furnace didn't run all day during the cold Wisconsin winters. The government rebates or tax credits are usually a one time deal. They may pay for part of your installation, but they won't cover the whole cost. The only thing I've heard of that will pay you every year is a wind generator tied into the electric grid, but thats another posting. I'm including a link to a site that will show you how to build a cheap solar heater that you can try yourself.
Q: How do solar panels affect the property's overall cost savings?
Solar panels can significantly impact a property's overall cost savings by reducing or eliminating electricity bills. As solar panels generate electricity from sunlight, they offset the need for grid power, resulting in lower energy expenses. Additionally, excess energy can be sold back to the grid, further increasing savings. While the initial investment for solar panels may be high, the long-term financial benefits and potential tax incentives make them a worthwhile addition to any property.
Q: Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?
500 Watt Solar Panel
Q: There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
in case you positioned 'photograph voltaic international information' right into a seek engine, you will discover that there are a number of information that are being heavily contested. choosing up the reality from between hype is the activity. photograph voltaic panels generally have a rated optimal output of approximately one hundred ten watts consistent with squaremetre. yet relatively delivery to grids of kWh might element to a huge determination closer to fourteen watts / squareM. on a 24 hour foundation. Grid administration is for that reason careful approximately yield claims whilst history factors to in basic terms a million/8 of rated optimal output. there may be some irrelevant expectancies, whilst a photograph voltaic roof is first powering the construction, and in basic terms advertising extra to the grid.
