Q: is this fact true? - its a limitation to solar panels during summer when it's in extremly hot countrie. I've heard it from my science teacher .. please give detail if you have any and any more benefits/limitations is welcomed .. Thank you :) !: WHAT? This is far from the truth, IN Scottsdale Arizona a small apartment complex was fitted with solar {photo voltaic cells in the late 70s. Every summer they sold electricity back to the power company. It gets up to 5 fairly often here, and as hot as 23 in the shade. On a roof top it is over 50 in direct sunlight. The opposite is true. When it is cloudy they produce less electricity. They may loose some efficiency when it is very hot, but not enough to make them not work at all, or even enough to really harm the output to any really appreciable extent. A new plastic photovoltaic material that produces about 40-45% of a silicon based solar cell is a neat option as it works when it is very cloudy, you can drive nails through it, and it is flexible. I think these items are kept artificially expensive by big business, but this is just a biased opinion of mine, but as far as not working in extreme heat, NO these solar panels work just fine when it is hot. I am in Phoenix Arizona, and it does not get a whole lot hotter than here. If the cells from the 970s worked OK newer ones are better and will do just fine too. Solar hot water heaters are a slightly different matter as they will over heat the water and the water must be mixed with cooler water, or you can really get into trouble. Maybe this is what he meant. Still I doubt it is enough of an issue to cause the device to be less efficient than a gas water heater, or electric, etc. Maybe he is referring to having to mix cooler water into solar heated water in a solar hot water heater, or some other system, Photovoltaic cells do not have any problems rendering them useless from hot weather on this planet, and in fact, they are used in space and it gets much hotter there.

Q: During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :): If okorder If you have a fair chunk of money to drop on a standing seam steel roof, check out who Powerfilm has as their preferred installers for their roofing panels.

Q: where I can find solar panel the has 4.8 volts? Like those solar walkway light or something that has 4.8 volts solar panel.Do you think I can get it from home depot?: How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.

Q: Can solar panels be installed on a carport structure?: Yes, solar panels can be installed on a carport structure. In fact, carports are a popular choice for solar panel installations because they provide a dual purpose of providing shade for vehicles while generating clean, renewable energy. The structure of a carport offers ample space for solar panels to be mounted, allowing for efficient energy production while maximizing the use of available space.

Q: Can solar panels be installed on parking lots?: Yes, solar panels can be installed on parking lots. In fact, it is becoming increasingly common to install solar panels on parking lots as it allows for optimal utilization of available space while generating clean and renewable energy. Additionally, solar panels installed on parking lots can provide shade, reduce heat island effect, and serve as electric vehicle charging stations, making it a sustainable and efficient solution.

Q: 3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts: It is cheaper to have a solar regulator to extend the battery lifespan. A lead acid battery can vent hydrogen if charged too much and run out of electrolytes. The battery would cost more than a $30 5 amp solar regulator.

Q: If not how do they give power to a house/a company?: Solar panels can be connected to your household wiring with a piece of equipment called a grid tie inverter. You power company will probably require either an automatic or manual means for disconnecting your equipment from their grid in the event of a power outage or line maintainence. Homepower Magazine is an excellent source for information about solar and other alternative energy sources. A primer on the basics of solar electricity can be found using the first link below. You can download a free sample issue of the magazine using the second link below. The sample issue being offered changes occasionally. Don

Q: Is this a good kit for building a solar panel?: Guide okorder /

Q: I was having a discussion with a friends about solar panels.He says that if there is a solar panel (sp) on the ground and a solar panel (sp2) high in the atmosphere (in the stratosphere) the difference in power output between sp and sp2 negligible. I said that there would be a large difference in power output because sp has all of the atmosphere to block the suns rays and sp2 has very little atmosphere because it is very high up (in the stratosphere) therefore more sun can get to the panel and more power is produced.who is correct? many thanks in advance, please leave sources if possible, for validity.: Guide okorder /

Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.: You would need to consider how much sun your area gets on average. You would need to do a cost/benefit analysis to decide if you will be saving money eventually. Environmentally, it would not affect the plants or animals around it, except those it might block the sun from. Meaning, the grass growing in the shade of the panels will probably die out, but that goes for anything that would cast shade for the majority of the time. Solar panels are simply rechargers for the batteries it's hooked up to. No different than a cell phone charger affects the area, people or plants around it. If it is a worry, make some orgonite and place it around the panels. :)
