- Q: How do solar panels affect the overall resilience of a building?
- Solar panels can significantly enhance the overall resilience of a building. By generating clean and renewable energy, they reduce dependence on traditional power grids, making the building less vulnerable to power outages or disruptions. Additionally, solar panels can provide a reliable source of electricity during emergencies, ensuring critical systems like lighting or communication remain operational. The energy independence offered by solar panels enhances the building's ability to withstand and recover from various crises, ultimately improving its overall resilience.
- Q: I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
- Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
- Q: Can solar panels be installed on schools or educational campuses?
- Yes, solar panels can be installed on schools or educational campuses. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their power needs. Installing solar panels on schools not only reduces electricity costs but also serves as an educational tool, allowing students to learn about renewable energy and environmental sustainability firsthand.
- Q: Do solar panels require a backup generator?
- No, solar panels do not require a backup generator. They generate electricity from sunlight, so as long as there is sufficient sunlight, they can provide continuous power without the need for a backup generator.
- Q: Maximum size of solar panel i have to use is - 8 * 5 feet - this is the limitation given to us.
- go buy some 90's Arco solar panels. they're about 2x5 inches and produce 60 watts (24 volts x 2 amps) in full sunlight. then mount them up on a rig that tracks the path of the sun all day long. not all solar panels are created the same. the ones you get at harbor freight will be less efficient than the ones you buy from some guy whose father got the panel as a gift from a business party in the 990s.
- Q: Can solar panels be installed on agricultural or farming operations?
- Yes, solar panels can be installed on agricultural or farming operations. In fact, many farmers and agricultural businesses are increasingly adopting solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be mounted on rooftops, open land, or even on barns and sheds, providing clean and renewable energy to offset electricity costs and reduce carbon emissions. Additionally, solar panels can help farmers take advantage of unused or underutilized land, providing dual benefits of energy generation and agricultural productivity.
- Q: Do solar panels require a battery for energy storage?
- No, solar panels do not necessarily require a battery for energy storage. While batteries can be used to store excess energy generated by solar panels for later use, it is not a mandatory component. Solar panels can also directly feed the generated electricity into the grid or be used to power devices in real-time, without the need for a battery.
- Q: What is a good sight that I could go to about installing solar panels and all of the considerations of it?
- Just okorder
- Q: . Do they scratch easily? How do I remove snow from them without scratching them?2. What does the upkeep of many solar panels consist of? I want to have my electricity completely off of the grid.3. Are all solar panels made from the same material, regardless of size?
- anythign can be scratched/ruined/altered if not tended to properly.... remove the first biggest layer of snow and leave a lil under to try to see first if it melts away on its own (dpeendin what season of course) if not than get some luke warm water and soak the snow.... slosh it off with a rubber shovel or mop.broom whatever wont damage ur panels. anythign you take care of will last longer and take care of you.... and solar is expensive to put in and can be expensive to maintain . depends where you have most sun and depends how many resources you use, if you leave the tv on absent mindely all night and take 50 min showers or blast the heat with jsut on epathetic lil donwpour of rain instead of just BUNDLING UP like a alot of lazy *** ameicans and.or rich careless bastards of course youa re goign to be paying up and out of your asshhhhh-hooooo and nooooo there are some different materials solar panels are made of, there is a main base/core they use but im sure there are AT MOST two...the rest is either glass or plastic! depends for what you want and how many , includign size.... good luck!!!! excuse my typos
- Q: I don't see much solar panels on people's houses where I live. I got a long time to go before doing so but I was planning on buying a few solar panels when I retire in the far future. In your opinion, is such an investment worth it? Would you buy them? I realize they are very expensive hence why I said when I retire. Thanks for your opinion
- The payback is usually between about 5 and 5 years depending on how expensive electricity is in your area, the rebates available, and where you live (is it sunny most of the time?) Most people that get them don't do it for the investment - they do it to be energy responsible - but it's not a bad way to do both if you have the money to put into it. I personally just pay for the green energy option from my electricity provider. So I am buying power from solar and wind farms, and it cost about 0% more per month. I don't get the benefit of free power, but it comes with a smaller price tag initially, and I think when we all invest in these technologies, the price will improve over time, so energy costs will be lower in the future.
