Q: solar panels!!they are fantastic! cause they are the new way of quot;chargingyour home, without killing the earth!would you install them, or not? and make sure you say WHY: Why: ) It's a great technology. 2) It has low impact to the environment. Why Not: ) Initial cost is substantial. 2) solar panel technology is greatly improving. I would hold out for a few more years when you can actually use it as a sustainable source and as a replacement source and not so much a suplimentary source.

Q: Got a quote for about $K today for solar panels to save me about $00 a month on my electric bill. I was just wondering if anyone had successfully bought and installed their own and how it worked for you?: Hello, okorder /

Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?: Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.

Q: How does the snow cover get removed from the panels?: Green energy magically makes the snow transparent. The more I learn about solar and wind, particularly selling excess power back to the utility, the less sense it makes. You'll have noticed, perhaps, that there was no way to store the power from the panels for when it's really needed.

Q: i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel: [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.

Q: I have created a solar setup in my shed i have 2x.5w solar panels i am hoping to charge my 55ah car battery how long would it take to charge the battery and how many watts could i used a day: To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.

Q: about solar panel: The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.

Q: Can solar panels be used to power a sports car?: Yes, solar panels can be used to power a sports car. By installing solar panels on the vehicle, the sun's energy can be harnessed and converted into electricity to charge the car's battery, potentially extending its range. This technology is still in development, but several concepts and prototypes have been created, showing the potential for solar-powered sports cars in the future.

Q: How do solar panels affect my electricity bill?: Solar panels can significantly reduce your electricity bill by generating electricity from the sun's energy. This self-generated electricity can power your home or business, reducing the amount of electricity you need to purchase from the grid. In some cases, if your solar panels produce more electricity than you consume, you may even receive credit or payment for the excess energy fed back into the grid.

Q: Can solar panels be used in areas with high levels of saltwater exposure?: Yes, solar panels can be used in areas with high levels of saltwater exposure, but they may require additional maintenance and protection measures to prevent corrosion and damage from salty air and water.
