- Q: Ok Im trying to power my room using solar panels and I've figure out that I need about 700 watts to do so, but I really only use my electronics at night. I was wondering if I could buy lets say a 200 watt solar panel and let it charge a battery all day would that work? I live in southern california so I dont have to worry to much about cloudy days. also any suggestions on where to buy a panel, inverter, charge regulator, and battery?
- You would probably need several batteries. 700 watts means about 40 Amps from a 2 volt battery. That is a lot of current. You need to loot at how may watt-hours you need. And how many amp-hours for the batteries.
- Q: Are there any restrictions or regulations regarding solar panel installations?
- Yes, there are restrictions and regulations regarding solar panel installations. These can vary depending on the location and jurisdiction. Common regulations include obtaining permits, adhering to building codes and zoning requirements, maintaining a certain distance from property lines, and complying with electrical and safety standards. It is important to consult with local authorities and professionals to ensure compliance with all applicable regulations before installing solar panels.
- Q: I am trying to built a circuit that will power two USB ports (both 5V and 0.5 amps) from the output of a solar panel that produces 20V at 0.2 amps. I have a voltage regulator that runs at 5v and 0.5 amps but I can't figure out the best way to boost the current up to 0.5 amps before I incorporate the voltage regulators.
- If you want to power both USB ports at the same times, It might not be possibble. Your solar panel only supplies 2.24 Watts (20V * 0.2A) of power and you need to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses from your regulator(s), you will be WAY over your power budget. You will need more of a solar panel or less of a load.
- Q: Can solar panels be used in countries with limited sunlight?
- Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in regions with abundant sunlight, they can still generate electricity in areas with less sunlight. Even countries with limited sunlight exposure can benefit from solar energy by utilizing advanced solar technologies and optimizing panel placement to maximize energy production. Additionally, solar panels can still generate electricity on cloudy or overcast days, although at a reduced efficiency compared to sunny days.
- Q: Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?
- 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: Hi I need to replace the solar panel on my calculator and was wondering where I could buy one. Thanks in advance for your answers.
- My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
- Q: Can solar panels be used in areas with high winds?
- Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panel installation is designed and built to withstand the specific wind conditions of that area. This may involve using appropriate mounting systems, securing the panels properly, and considering the orientation and tilt angles. Additionally, selecting high-quality materials and conducting regular maintenance can help ensure the longevity and performance of the solar panels in high wind areas.
- Q: I installed a 60watt solar panel on the top of my patio/pergola. This is wired to a charge controller then a battery in my basement. Do I need to run a ground from the solar panel? If so, whats the easiest way to do so? Is a wire attached to the aluminum frame then connected to a foot long rod into the ground enough?

- Q: Can solar panels be used to power a drone?
- Yes, solar panels can be used to power a drone. By harnessing sunlight, the solar panels can convert the energy into electrical power that can be used to charge the drone's batteries or directly power its motors. This enables drones to have longer flight times and potentially operate in remote areas without the need for frequent battery replacements. However, the practicality and effectiveness of solar-powered drones may depend on factors such as the size and efficiency of the solar panels, weather conditions, and the power requirements of the drone.
