Q:Can solar panels be installed in areas with high levels of air pollution?
Yes, solar panels can be installed in areas with high levels of air pollution. While air pollution can potentially have a slight impact on the efficiency of solar panels, it is not a significant barrier to their installation and operation. Solar panels primarily rely on sunlight, which is still present even in polluted areas. Additionally, solar panels can even contribute to reducing air pollution by providing clean energy alternatives.
Q:Is it really possible for me living in Denver to build and install and setup my own solar panel to help make electricity for my home?
It's okorder / has something to say about various scams, including solar.
Q:Can solar panels be used in areas with frequent lightning storms?
Yes, solar panels can be used in areas with frequent lightning storms. While lightning poses a potential risk, modern solar panels are designed with safety features to mitigate the impact of lightning strikes. These features include grounding systems, surge protectors, and lightning arrestors. Additionally, solar panels are built to withstand extreme weather conditions, including lightning storms, ensuring their durability and functionality in such areas.
Q:Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
It would work better to put the solar panels on the ground beneath the windmills. Land underneath wind farms is perfectly usable for other things, and it gets plenty of sun. But then, if you think about good places for solar panels, parking lots make even more sense yet. There's plenty of em, and people like to park in the shade.
Q:Are solar panels easy to maintain?
Solar panels are generally easy to maintain as they have no moving parts and require minimal attention. Regular cleaning to remove dust and debris, as well as occasional inspection for any damage or shading, is usually sufficient to ensure optimal performance.
Q:we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?
A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
Q:i really need to know howbecause im building a solar powered car for science fair :]thank you!
get some stuff, put it on the other stuff
Q:I want to add solar panels to my home. I was looking online and it seems there are so many different kinds! How does it hook up to the electrical grid? How much do I need for a 2000 sf home?
There are different solar panels for different uses For a domestic home it all depends on how much electricity you are going to use per month or per year For a normal use home (2 adults, 2 children) I presume one need to install a panels that would produce about4 to 5000 Kilo wats of energy per year Based on the type and the out put of the panels the suppler and the person who is advising you will guide you how many panels you will be requiring to install Take a professional help They are better informed and also knowledgeable
Q:Can solar panels be used for large-scale power generation?
Yes, solar panels can definitely be used for large-scale power generation. With advancements in technology and decreasing costs, solar power has become a viable option for utility-scale projects. Large solar farms comprising thousands of panels are being built around the world to generate electricity on a massive scale. These solar installations have the potential to provide clean and sustainable energy for cities, industries, and even entire regions.
Q:Can solar panels be used to power a zoo?
Yes, solar panels can be used to power a zoo. Solar panels can generate electricity by converting sunlight into energy. This renewable energy source can effectively power various operations within a zoo, including lighting, heating, cooling, and powering animal enclosures, as well as other facilities such as gift shops and food stands. By utilizing solar panels, zoos can reduce their dependency on fossil fuels, lower their carbon footprint, and contribute to a more sustainable and environmentally friendly operation.
