Q: can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.
Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?
I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.
Q: Can solar panels be used in areas with high temperatures?
Yes, solar panels can be used in areas with high temperatures. In fact, solar panels are designed to withstand a wide range of environmental conditions, including high temperatures. However, it's important to note that extreme heat can slightly reduce the efficiency of solar panels, but this reduction is usually minimal and does not significantly impact their overall performance. Additionally, proper installation and maintenance can help mitigate any potential heat-related issues.
Q: Can solar panels be used to power streetlights or outdoor lighting?
Yes, solar panels can be used to power streetlights or outdoor lighting. Solar streetlights are becoming increasingly popular as they provide a sustainable and cost-effective solution for outdoor lighting. Solar panels capture sunlight and convert it into electricity, which can then be stored in batteries and used to power streetlights during the night. This not only reduces dependence on traditional energy sources but also helps to reduce carbon emissions and overall energy costs.
Q: Can solar panels be installed on multi-story buildings?
Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings often provide ample space on rooftops for solar panel installation.
Q: I'm going to this camp and the instructors asked us to be prepared tomorrow to build a sun tracker for a solar panel. Does any one have any ideas, tips, or advice?
Since the sun moves in the sky on a very predicatable course you don't need a closed loop control system to track it. All you need is a clock-drive motor and the proper gearing for your latitude. The clock drive motor will move at a constant rotational velocity based on time, and when it is geared down properly the angle of the shaft will follow the sun. Make sure the clock motor is powerful enough to move the solar panel, etc. That's a start, anyway. .
Q: For example, If I were powering my house with solar panels, would it be more efficient or effective, (or I guess would I get more energy) out of a day that measured 90 degrees Fahrenheit as opposed to a day that is 70 degrees Fahrenheit.
If you are talking about solar PV (photovoltaic), panels, (these are the solar panels that generate electricity), temperature DOES effect the power output. But it works opposite of your example. They actually work better in cooler temperatures. In other words, you will get more electricity on a cold, sunny day than you will on a warm, sunny day. The difference is not huge. It is a percentage point or two for every ten degrees cooler it is. But it is significant enough that solar system designers like myself need to know the temperature fluctuations in the area we are designing for. I know of a few improperly designed systems that were damaged on sunny winter days. Solar thermal panels (the ones that heat water) do not work this way. A warmer sunny day is usually better, but again, the difference is not huge.
Q: Can solar panels be installed on a high-rise building?
Yes, solar panels can be installed on a high-rise building. In fact, high-rise buildings can be ideal locations for solar panel installation due to their height and large surface areas. By utilizing the available roof space, high-rise buildings can generate significant amounts of solar energy, helping to reduce their reliance on traditional energy sources and lowering their carbon footprint.
Q: Can solar panels be used for powering agricultural irrigation systems?
Yes, solar panels can be used to power agricultural irrigation systems. Solar-powered irrigation systems are increasingly being used in agriculture as they provide a sustainable and cost-effective solution. Solar panels convert sunlight into electricity, which can then be used to power pumps and other irrigation equipment, reducing reliance on fossil fuels and electricity grids. This approach helps farmers save on energy costs and reduces their carbon footprint.
