Q: Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.
you could use a water container with the sun focased on it and make it so that the water that gets heated goes out of a tube near the middle and the tube would lead to a turbine that generates electricity when water is forced through the tube( like an IV machine pump they use in hospitols only reversed so that it generates power instead of using power) then lead the tube back to the very top to release the water. PS basic principle behind idea is that water moves when heated and slows when cooled HARNESS THAT ENERGY
Q: Can solar panels be installed on farmlands or agricultural fields?
Yes, solar panels can be installed on farmlands or agricultural fields. In fact, many farmers and landowners are increasingly using their land for solar energy production as it can provide additional income and sustainable farming practices. Solar panels can be mounted on ground-mounted systems or integrated into structures like barns or sheds without interfering with farming operations. Additionally, solar installations can offer benefits such as reduced energy costs and promoting environmental sustainability in the agriculture sector.
Q: How do solar panels affect the property's operating costs?
Solar panels can significantly reduce a property's operating costs by generating clean and renewable electricity. By harnessing sunlight, solar panels can power various appliances and systems, reducing or even eliminating the need to rely on expensive grid electricity. This can lead to substantial savings on utility bills, making solar panels a financially sound investment for property owners.
Q: Can solar panels be installed in areas with heavy snowfall?
Yes, solar panels can be installed in areas with heavy snowfall. However, proper installation, design, and maintenance considerations are essential to ensure their effectiveness. Snow accumulation can temporarily reduce solar panel output, but the panels are typically designed to be slanted, allowing the snow to slide off. Additionally, advancements in technology, such as snow-clearing systems and anti-reflective coatings, can further enhance solar panel efficiency in snowy conditions.
Q: So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
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: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q: How do solar panels perform in cloudy weather?
Solar panels do generate electricity even in cloudy weather, although their efficiency is reduced compared to sunny days.
Q: Can solar panels be installed on a school or educational institution?
Yes, solar panels can be installed on a school or educational institution. In fact, many educational institutions are now adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. Installing solar panels not only reduces carbon footprint and saves on energy costs but also provides an opportunity for students to learn about renewable energy and sustainable practices.
Q: Can solar panels be installed on universities or educational campuses?
Yes, solar panels can certainly be installed on universities or educational campuses. In fact, many educational institutions worldwide have already embraced solar power as a sustainable and renewable energy source. Installing solar panels on campuses not only helps reduce carbon emissions and combat climate change but also serves as a great educational tool for students to learn about clean energy and sustainability. Additionally, universities can benefit from cost savings on electricity bills and even generate surplus energy that can be fed back into the grid.
