Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.: If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.

Q: Can solar panels be installed in rural areas?: Yes, solar panels can be installed in rural areas. In fact, rural areas often have more space and sunlight, making them ideal for solar energy generation. Installing solar panels in rural areas can provide access to clean and renewable energy, reduce reliance on fossil fuels, and bring electricity to remote communities that are not connected to the grid.

Q: How do solar panels affect roof aesthetics?: Solar panels can have both positive and negative effects on roof aesthetics. On one hand, solar panels can enhance the look of a roof by providing a sleek and modern appearance, especially when integrated seamlessly into the roof design. On the other hand, some may argue that solar panels can detract from the overall aesthetic appeal of a roof, particularly if they are bulky or installed in a way that is visually obtrusive. However, with advances in solar panel technology, it is now possible to find more aesthetically pleasing options that blend well with different types of roofs, making them a viable option for homeowners concerned about both energy efficiency and the visual appeal of their roofs.

Q: Can solar panels be used to power a school?: Yes, solar panels can definitely be used to power a school. Solar panels convert sunlight into electricity, which can be used to power various electrical systems within a school, including lighting, heating/cooling systems, computers, and other appliances. By harnessing solar energy, schools can reduce their dependence on traditional sources of electricity and contribute to a more sustainable and eco-friendly environment.

Q: Solar panel for battary charging: Check the rating on the battery. Either look on the label, or look up the exact manufacturer's part number on the internet. There should be an amp-hour (AH) rating. It's very doubtful that the battery is 65 AH, by the way. When you get the amp-hour rating, people can advise you further.

Q: Can solar panels be used to power a restaurant?: Yes, solar panels can be used to power a restaurant. By installing solar panels on the rooftop or in a nearby area, the restaurant can generate clean and renewable energy to meet its electricity needs. These panels convert sunlight into electricity, which can power various appliances, lighting, and other electrical systems within the restaurant. Additionally, solar panels can help reduce the restaurant's reliance on the traditional power grid, leading to potential cost savings and environmental benefits.

Q: I know the basics of how solar panels work. Solar panels convert sunlight into DC electricity which is stored in batteries which would need to be run through an inverter to convert it to household AC. But is there a way for the appliances to use the solar panels electricity FIRST and any additional power from the grid? Is that how it works or do they only run specific devices(water heater, pool pump, etc)?: The utility is your battery. Doesn't make any difference which is used first. At least that's the case in Calif. However, you need an electrician to do the attachment, and probably an inspection by the utility.

Q: How do solar panels affect roof weight load?: Solar panels can increase the weight load on a roof, but their impact is generally minimal. The weight of solar panels is usually evenly distributed across the roof surface, and most roofs are designed to handle this additional load without any issues. However, it is recommended to consult with a professional to assess the roof's structural integrity and ensure it can support the added weight of solar panels.

Q: I want to build a standalone wifi repeater -- powered by the sun. The problem is how much solar power and how big of a battery?net draw 4.5v @ 0.66A with loadnet draw 4.5v @ 0.60A no loadI'm assuming the best choice would be a 6v battery with a a couple diodes in series to induce ~.5v drop. Then, I need something to charge it -- I found 2v 6w solar chargers in the automotive section of Sears and 6v 2w solar chargers in the marine section of Dick's Sporting Goods.How many solar panels and what capacity batteries should I use? Is this the best method or should I use a voltage regulator and go with 2v batteries?I need this to be as cheap and simple as possible...: You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)

Q: Can solar panels be used in areas with high levels of noise from transportation?: Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not affect the functionality of solar panels as they primarily rely on sunlight to generate electricity. However, it's important to ensure that the panels are properly installed and maintained to maximize their efficiency and minimize any potential disruptions caused by noise pollution.
