Q: I think that solar panels are the future and i think that the conventional way of generating electricity is going to be replaced by solar panels. I would like to be part of this industry as an entrepreneur but i do not know how to since i do not have a technical background. I would like to sell solar panels to consumers and to business. Should I start a manufacturing company that manufactures solar panels? Should I buy solar panels from manufactures and sell them to consumers? What should I do?
actually, i think of it rather is an extremely lifelike purpose for recuperating air high quality and suplying skill. you will not go with to apply it as a highway floor, as deposits from tire treads might degrade its productiveness, yet one among those equipment could actually be built alongside roadways and rail structures. Panels would not could be as extensive as a roadway, as you have practically countless linear area. besides the undeniable fact that, i don't think of it will make a distinction in worldwide climate replace. the time-honored utilising tension for worldwide warming isn't guy-made polution, yet organic phenomena which contain volcanic eruptions. human beings in all probability have some effect, yet its slightly like the entire tea-cup-in-the-swimming-pool difficulty. there is not something that could be executed approximately worldwide warming. keep in mind that the earth's climate is in a relentless cycle from chilly to warm, and back to chilly. i'm confident you have heard of ice a protracted time.
Q: How much would solar panels cost for: A Cell phoneA average houseA car
in case you recognize the place to look you get get image voltaic panels for 0 expenses. as an occasion, numerous sign companies use image voltaic panels. touch your interior sight sign company and tell them you will haul off all their broken image voltaic panel for loose. they're oftentimes extra beneficial than keen to assist you are trying this.
Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
Q: I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
confident. this relies upon and the dimensions and performance of the image voltaic panel and the capability intake of the easy bulb. in case you % consistent capability whilst the solar isn't attainable, the panel must additionally be powering a financial business enterprise of batteries and capability drawn from them. My closest publicity to image voltaic panels turn right into a neighbor who took a single one with him tenting to capability a single fan. It did an excellent activity of airing his tent throughout the day so it did no longer warmth like an oven. This turn into an application the place the capability turn into in simple terms mandatory whilst the solar turn into shining. evaluate to windmills initially put in to pump water for livestock and retrofitted with electricity turbines *and* a storage battery. the ordinary use for the electrical powered energy turn into for listening to radio interior the evening, whilst the reception turn into extra effectual. The use with a battery somewhat than in simple terms for instantaneous capability is shown as being the norm somewhat than the exception in living house applications.
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?
A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.
Q: If i wanted to get a 5 KW solar Panel does it mean it produces 5KW a day/hour/year!?!?i need 2555.35KW a week and i don't know how many or what kind of solar panels i need.Please somebody help me
It means that it will produce (at best) 5kW when the sun is shining in an ideal position, in hour that's 5kWh so, on a good summer day it may produce a total of 25kWh nothing at night see the link for a 5kW system, you need at least 0 possibly 20 times that.
Q: Can solar panels be used for charging batteries?
Yes, solar panels can be used for charging batteries. Solar panels convert sunlight into electricity, which can be used to charge batteries and store energy for later use. This process is commonly used in off-grid systems or to power portable devices and vehicles.
Q: I can't figure out how to charge a Ni Cd (BD 8V Firestorm) battery directly with a solar panel so I've come up with an alternative which might or might not work. I thought I would connect an inverter (I found a nice 400W for $30) to my trucks battery and plug the BD Firestorm battery charger into the inverter. Then I was thinking I could use a 5W solar panel to trickle charge the truck battery and keep it connected after the Ni Cd is charged to ensure the truck battery is topped off. The truck would not be running during this process. Will this solution work? Is there a better solution?
Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
Q: The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m? x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
Q: How do solar panels affect the overall air quality of a building?
Solar panels have a positive impact on the overall air quality of a building. They generate clean and renewable energy, reducing the need for fossil fuel-based power generation. By avoiding the burning of fossil fuels, solar panels contribute to decreased air pollution, including the release of greenhouse gases and harmful particulate matter. Thus, solar panels help improve the air quality inside and outside the building, promoting a healthier environment for occupants and the surrounding community.
