- Q: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.
- The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
- Q: How much space is required for solar panel installation?
- The amount of space required for solar panel installation depends on various factors, including the size and number of panels, their efficiency, and the energy needs of the property. On average, a residential solar system typically requires around 100-400 square feet of roof space per kilowatt of installed capacity. However, ground-mounted systems can require larger areas, while more efficient panels may require less space. It is recommended to consult with a solar installer to assess the specific space requirements for your installation.
- Q: I'm looking at solar panels and I have NO IDEA what this stuff means.They come in catagories of Watts. What does that refer to? If a solar pannel is in the 200-watt catagory, what does that really mean? Will it produce 200 watts an hour, a day, a week, a month, a year?? How many watts of energy does the average house use up in one month? I really wish they would just tell me on the website!! :(0 points!!!!!!!! :D
- Watts is a measurement of power which is a combination of Voltage x Amps Example: a 200 Watt panel can produce 6.6 amps at 2 Volts. (200 = 2 x 6.6) If you bought a 24 volt system the same 200 Watts would give you half the amount of amps since the power (watts) is the same. When determining your needs for a solar system there are many factors that have to be taken into account. The amount of power you use will depend on what appliances you have in the house, how much you use them, and how careful you are with vampire loads (A TV or stereo will use some power even when turned off unless you unplug them). The amount of panels you need will also depend on your battery system, amount of sunlight that you have in a day and how many days of reserve power you think you will need based on the weather in your area. If you wanted to completely run your house on solar energy you are looking at an investment of $5,000 - $20,000 or even more. There sometimes are tax incentive depending on where you live that will reduce your overall cost. Some examples of power usage: Toaster : 800-500W Microwave : 600-500W Dishwasher : 200-500W Washing Machine : 500W Vacuum Cleaner : 200-700W Iron : 000W Clothes dryer : 4000W Ceiling Fan : 0-50W Table Fan : 0-25W Electric Blanket : 200W Hair Blow dryer : 000W Electric Shaver : 5W Laptop Computer : 20-50W Desktop Computer : 80-50W TV (9 colour) : 70W Clock radio : W Fridge / Freezer : 500W 25 colour TV : 50W Electric Kettle : 2000W
- Q: Can solar panels be used in areas with high levels of volcanic activity?
- Yes, solar panels can be used in areas with high levels of volcanic activity. Volcanic activity does not directly affect the functionality of solar panels as long as they are installed safely. However, it is important to consider additional factors such as ash fallout, potential acid rain, and the need for regular cleaning and maintenance due to the volcanic environment.
- Q: Let's say I can buy solar panels for my business for $5,000 and my payback period is 8 years. Would it be correct to assume that my money is best spent elsewhere (such as paying down debt) if I am being charged an interest rate of 3.9%?
- Probably, however, depending on what your business does, solar panels can be a somewhat effective marketing strategy. Also you are helping the environment with your investment in solar panels. On a side note, I didn't think modern solar panels had a payback period of 8 years? From what I've heard it's more like 7 years. Oh well, I don't know much about this topic.
- Q: Can solar panels be used in areas with high levels of shade?
- Solar panels can still be used in areas with high levels of shade, but their efficiency may be significantly reduced. The shade from trees, buildings, or other obstructions can block sunlight from reaching the panels, limiting their ability to generate electricity. However, there are advanced technologies and strategies available, such as microinverters or optimizers, that can help mitigate the impact of shade and improve panel performance in shaded conditions.
- Q: Do solar panels require a specific type of inverter for converting DC to AC power?
- Yes, solar panels do require a specific type of inverter, known as a DC to AC inverter, to convert the direct current (DC) generated by the panels into alternating current (AC) power that can be used in homes and businesses.
- Q: Can solar panels be used to power a cruise ship?
- Yes, solar panels can be used to partially power a cruise ship. While it may not be feasible to solely rely on solar power for a cruise ship's energy needs due to its high energy demand, incorporating solar panels can help offset some of the energy consumption and reduce carbon emissions.
- Q: How do solar panels affect the insurance premiums of a property?
- Solar panels can have both positive and negative effects on insurance premiums. On one hand, having solar panels installed on a property can increase its overall value, which may lead to higher replacement costs in case of damage or loss. This could potentially increase insurance premiums. However, many insurance companies also offer discounts for properties with solar panels, as they are considered a risk mitigation measure. The extent to which solar panels affect insurance premiums can vary depending on the specific policies and guidelines of the insurance provider.
- Q: Is this true in a dc system? What if my battery current is negative?
- I am not sure about your question ? If your Q is, what is the solar panels current output, it is 8.73A regardless of the load. If the Q is, How much extra current is available in this circuit, the answer is 3.58A ( 8.73 - 4.32-.83= 3.58)
