Q: I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
You are probably going to need about 60 panles and 60 batteries....you will also need a very good power inverter. Also consider the power it takes to invert 2 volt DC battery power in to 20 volts AC power required for an air conditioner. You might consider also trying to find a 2 or a 24 volt unit cooler. You would be better off buying a generator. Solar panels and batteries are not going to run an air conditioner for long if at all.....it might be cheaper to have the power company run the power.
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: i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?
While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .
Q: The battery is 9ah and the solar panel is 20w
You need a switch mode voltage converter, made to input 2 to 20 volts, and output around 7 volts. Some cell phone chargers can do that, or be modified for that voltage. Option B is to get another battery and use the system at 2V, and regulate that to 6 or 5 volts for charging (you can directly use your car charger), with switch mode regulators. I would find that system to be more flexible. Getting an 8Ah would leave extra capacity. BTW, for a 9AH battery, 20W is kid of big. I have a 36Ah battery and a 20W panel, and that is good for it.
Q: Can solar panels be installed on community buildings?
Yes, solar panels can be installed on community buildings. In fact, community buildings like schools, libraries, and community centers are excellent candidates for solar panel installations as they often have large roofs or open spaces that can accommodate solar arrays. Installing solar panels on community buildings not only helps reduce electricity costs but also promotes sustainability and clean energy in the community.
Q: i would like to hook up a power outlet to a solar panelmy light system is 500watts will run for 8 hours/day between noon to 8PM.So what is the most effective system do I need?
You CANNOT directly hook up anything to your solar panel that is ac as your solar panel is dc. You need several things in order to make it work correctly. I have put up a small diagram of how basic solar works and have included a link below where you can see it. Then if you have further questions, I will be more than happy to answer them for you if I can. Thanks Rock
Q: Can solar panels power an entire house?
Yes, solar panels can power an entire house. The number of panels required depends on the energy needs of the house and the amount of sunlight available in the area. However, with proper installation and integration of a solar panel system, it is possible to generate enough electricity to meet the needs of an entire house, including appliances, lighting, heating, and cooling systems.
Q: Can solar panels be installed on a flat roof?
Yes, solar panels can be installed on a flat roof. However, it is important to consider the orientation, tilt, and shading of the roof to ensure maximum efficiency and productivity of the solar panels.
Q: What is the average size of a solar panel?
The average size of a solar panel is typically around 65 inches by 39 inches, or approximately 5.4 feet by 3.25 feet. However, the actual size can vary depending on the manufacturer and the specific model of the solar panel.
Q: I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
