Q:Solar panel for laptop?
laptop don't get enough power.
Q:Charging batteries with a solar panel?
Batteries will not stop charging on their own. The will stop charging when the battery voltage equals the supply voltage. Solar panel open circuit voltage is typically around 20V. Batteries will just boil dry before reaching 20V. One rule of thumb, above 0W you need a controller for sure.
Q:How can a solar panel work for me?
Sounds okorder.com.. I've seen the particular device listed there. While the lamp is mediocre for an LED light source, the panel is excellent - real polysilicon wafers, in an aluminum frame. Same construction as the kind of panels in commercial installations.
Q:Single Solar Panel savings?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q:Why don't scientists use the design of a tree for solar panels?
From the vantage point of a scientist and an engineer, you have a whole host of problems to overcome. The mass of solar cells cannot be supported by most leaves much less allow the leaves to turn toward the sun as they naturally do. The wood and other structures of a tree are terrible conductors and wouldn't serve as efficient power transmitters. There are issues of damaging the health of the tree by interrupting the process of photosynthesis in favor of solar energy collection, and many other issues. However, I can tell you that solar power does use several principals that you have observed in trees. For example, solar collectors are almost always oriented to face toward the sun. Many adjust with the time of day and seasons to be optimally oriented to collect the sun's rays. Much like leaves in many plants are not static but change position to optimize their angle to the sun. Also, many solar cells are now designed with a membrane structure which offer several advantages. So you see many of your observations have found their way into practical application in solar power production.
Q:Self build solar panel ?
Homemade okorder.com
Q:Where can i find a list of solar panel manufactures worldwide?
Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo
Q:What does it mean when a solar panel is 50 watts?
Volts x amps = watts, so depending on what you want to run or charge will have to be taken into consideration. For example if you have a 0 volt TV @ 2 amps, then you're going to need 220 watts to power that. Best way to find out what it's volts and amps are, is to look on the back of the TV. But for batteries it doesn't matter, cause all batteries are is stored power, that can be later used, just use an inverter on them to convert DC to AC, also use a charger controller between the solar panels and the battery, cause you don't want the Solar panels to overcharge your battery and totally **** it up ______________________________________ But the more watts, the faster the power is returned; less watts, longer times. .
Q:What happens if I put a 00v, .5A solar panel on a 2V, 450cca Gel deep cycle battery?
The solar panel is capable of /2 Amp output. If you hook it to a 2V battery directly and the battery is discharged it will want more than /2 Amp and pull the voltage down until the battery is charged to a certain level. Eventually the battery will try to charge up to 00V which will definitely damage the battery. If you use a regulator circuit running off the solar panel that outputs 2V then you will have a constant voltage circuit which will still be limited to /2A or whatever the regulator is capable of outputting. Of course you can't just go out and connect 00V to any voltage regulator it has to be capable of running from 00V and dropping the voltage to 2V like the original charger that comes with the battery. The same explanation applies to a 72V battery. You have to limit the output voltage to 72V or risk overcharging the battery.
Q:Adding Solar Panels to my home in Portland, Oregon?
I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
