Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:How do you hook up solar panels to your electricity?
nowing what to do with unused renewable electricity is always a dilemma – hooking up to the grid has to be the preferred option. If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid. You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power. The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power. The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid. Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid. If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.
Q:Tips for convincing my school to put solar panels on the schools roof?
Installing solar cells cost money. It would swamp the capital spending portion of the school budget. I doubt the school board would put it into the budget because of the cost involved. If they did I guarantee you that, when presented to the voters, they would turn down the budget. If you really want to do something, I suggest a fund raiser, but you are probably looking at raising more than $500,000. Good luck.
Q:solar panel for computer?
Most decent laptops can use 50W of power or more....so you'd actually need a large solar panel with good sunlight. I just looked up how big a 50W solar panel is....it's about 64x64 centimeters...which is very big and expensive! So, solar power may not be the best solution to power, or charge a laptop battery. Maybe there are some solar powered chargers that charge the battery very slowly, but probably not.
Q:Please explain KW Solar Panels. What does it mean.?
I'm absolutely no expert within the field but hope to be trained rather more in the future. I am in the infancy stage of discovering as many choices as possible in the design and construction of a total inexperienced condo. That being stated, a distinctive nearby news story sparked my interest after they investigated the price effectiveness of residential sunlight panel systems. Here in Austin, Texas, through subsidies and incentives furnished, which you could set up a system that costs roughly 22.5k for about 7. It appears these deductions come from a federal incentive (which is a very small component) combined with those set by means of the city itself. Austin is an attractive modern city so I imagine their incentives maybe just a little higher than most however which you can call your city's common information line (3) and do a little more digging. Yet another option you might have is renting the equipment. I used to be advised the day gone by that a manufacturer here on the town would enable for the set up and use for a month-to-month rate. I know how tight cash will also be in school and 7 thousand might now not be tangible. The whole trouble of vigour conservation is so conventional nowadays that new information is constantly popping out. Give your current energy supplier a call and see what they may be able to inform ya. I am hoping you in finding anything that works for you. -G

Q:What do i need to use a 2v solar panel to charge a 6v lead acid battery as i cant find a 2v to 6v regulator?
You need a switch mode voltage converter, made to input 2 to 20 volts, and output around 7 volts. Some cell phone chargers can do that, or be modified for that voltage. Option B is to get another battery and use the system at 2V, and regulate that to 6 or 5 volts for charging (you can directly use your car charger), with switch mode regulators. I would find that system to be more flexible. Getting an 8Ah would leave extra capacity. BTW, for a 9AH battery, 20W is kid of big. I have a 36Ah battery and a 20W panel, and that is good for it.
Q:projector/solar panels help?
Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.
Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
Low cost solar panels are also extremely popular worldwide and China is a country that has been discovered to be excelling in this field as they manufacture the most economical solar panels when compared to any other country. Looking at the way things seem to be moving it seems that China will soon become a country to contend with because of their capabilities to manufacture things at extremely competitive prices. This fact is quite transparent for the simple reason that China appears to be getting more than double the number of orders. This can also be attributed to the fact that in spite of their low costs they have not only maintained but also improved on their quality too. For More Information You Can Refer To :
