Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.: Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.

Q: What is the main material for making solar panels?: You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.

Q: I want to be more green and if I get the panels will I still have a regular electric bill?: There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Q: Can solar panels be installed on a shaded area?: Solar panels can be installed in shaded areas, but they won't be as efficient as panels installed in direct sunlight. The amount of shade and the duration of shading throughout the day will impact the overall performance of the solar panels. It is recommended to install solar panels in areas with maximum sunlight exposure for optimal energy production.

Q: Hi. I hate the energy company. I hate my carbon footprint. I will likely move to a piece of property and put a decent-sized mobile home on it. I want solar panels so I can get my own power. I live in the state of Wisconsin. How much would this approximately cost? Would I need certain permits? How many panels can be used? Thanks for helping!: I'm not an expert on solar panels.... However, if you find they are expensive, I have a suggestion for eliminating a cost for heating... look into geo-thermal heating. It's a one time fee, they basically drill into the earth and heat your home with natural heat from underground. That wouldn't supply you all your power, but could cut down on the cost of solar panels, so you could use them simply for lights etc and not heat as well.... and I'm sure it would increase your re-sale value.

Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V: see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....

Q: I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?: One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .

Q: Are solar panels affected by shade?: Yes, solar panels are affected by shade. Shade can significantly reduce the efficiency and output of solar panels as shading obstructs sunlight, which is necessary for generating electricity. It is important to install solar panels in areas with minimal shade to maximize their performance and efficiency.

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: Can solar panels be used to power a satellite?: Yes, solar panels can be used to power a satellite. Solar panels on a satellite are designed to convert sunlight into electricity, which is then used to power various systems and instruments onboard the satellite. The panels are typically made of photovoltaic cells that generate electricity when exposed to sunlight, allowing satellites to operate in space where traditional power sources like batteries or fuel cells may not be practical.
