- 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: I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
- 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 used to power a military vehicle?
- Yes, solar panels can be used to power a military vehicle. Solar panels can be integrated onto the vehicle's surface to capture sunlight and convert it into electricity, which can then power various systems or even recharge the vehicle's battery. This can provide a more sustainable and renewable source of energy, reducing the reliance on traditional fuel sources and increasing the operational range of military vehicles.
- Q: Can solar panels be used in areas with high levels of chemical pollutants?
- Yes, solar panels can be used in areas with high levels of chemical pollutants. While chemical pollutants in the air or water may affect the efficiency or performance of solar panels to some extent, they are still capable of generating electricity in such areas. However, regular cleaning and maintenance of the panels may be required to ensure optimal performance and longevity in polluted environments.
- Q: Are solar panels weatherproof?
- Yes, solar panels are designed to be weatherproof and can withstand various weather conditions such as rain, snow, hail, and wind. They are made with durable materials and have protective coatings to ensure long-term performance even in harsh climates.
- Q: What is the cost of installing solar panels?
- The cost of installing solar panels can vary depending on various factors such as the size of the installation, location, type of panels, and additional equipment needed. On average, a residential solar panel system can cost anywhere between $10,000 to $30,000 or more. However, it's important to note that there may be potential tax incentives, rebates, and financing options available, which can help offset the upfront costs and make solar panel installations more affordable.
- Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
- It's depends on how many electrical appliances at home. For small house average need 800-200 watts electricity. The average solar panel kits produce 75-50 watts depending on the size of the panel. You needs minimum 5 solar panels.
- Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?
- In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.
- Q: Mitsubishi Solar Panels For Home Installation: How Much Do The Panels Cost?
- Mitsubishi solar panels are sold in pairs. I was in the market this week, checking on solar panels to install in my own house / workshop. Here's the price list I got from online and wholesale dealers for a pair of Mitsubishi panels: * Model MF20EC4 (20 watts) -- $590 * Model MF25UE5N (25 watts) -- $60 * Model MF75MF5 (75 watts) -- $799 * Model MF80UD4 (80 watts) -- $820 * Model MF85UD5 (85 watts) -- $850 BP Solar, PowerUp Solar GE Solar too have their own panels with a low-to-high price range. Go for BP solar panels as they're more affordable for home installation and good value for money.
- Q: How do solar panels affect the overall air quality of a building?
- Solar panels have a positive impact on the overall air quality of a building. They generate clean and renewable energy, reducing the need for fossil fuel-based power generation. By avoiding the burning of fossil fuels, solar panels contribute to decreased air pollution, including the release of greenhouse gases and harmful particulate matter. Thus, solar panels help improve the air quality inside and outside the building, promoting a healthier environment for occupants and the surrounding community.
