- Q: Are solar panels easy to maintain?
- Yes, solar panels are relatively easy to maintain. They require minimal upkeep, with regular cleaning to remove dust and debris for optimal efficiency. Additionally, occasional inspections to check for any damage or shading issues may be necessary. Overall, the maintenance requirements for solar panels are straightforward and manageable.
- Q: Are solar panels a good investment?
- Yes, solar panels are a good investment for several reasons. Firstly, they can significantly reduce or eliminate your electricity bills, resulting in long-term cost savings. Additionally, solar panels are environmentally friendly as they harness clean and renewable energy, reducing your carbon footprint. Furthermore, government incentives and tax credits are often available, making solar panel installation more affordable. Lastly, solar panels can increase the value of your property, providing a return on investment if you decide to sell in the future.
- Q: Can solar panels be used in areas with high levels of dust or sandstorms?
- Yes, solar panels can be used in areas with high levels of dust or sandstorms. However, frequent and heavy exposure to dust or sand can reduce their efficiency over time. Regular cleaning and maintenance are necessary to ensure optimal performance in such areas. Additionally, advanced solar panel designs and coatings are being developed to mitigate the impact of dust and sand accumulation, making them more suitable for use in these challenging environments.
- Q: I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician
- If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
- Q: Can solar panels be installed on a billboard or signage?
- Yes, solar panels can be installed on billboards or signage.
- Q: If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?
- Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.
- Q: Are there any tax credits available for installing solar panels?
- Yes, there are tax credits available for installing solar panels. The federal government offers a Solar Investment Tax Credit (ITC), which allows homeowners and businesses to deduct a percentage of the cost of purchasing and installing solar panels from their federal taxes. Additionally, some states and local jurisdictions also provide their own incentives and tax credits for solar panel installations.
- Q: Since plants have been populating this earth for the past 475 million years I think they have evolved to gain the most sun with their greenery. If scientists used heat sensors to find the hot spots of trees and trim all of the leaves that don't quot;providefor the plant, then maybe that trimmed tree could be used to become a solar quot;panelquot;. I believe that each individual leaf could be replaced by a small solar panel and the wood of the tree would be wiring that would root all of the solar panels to a generator.
- solar panels do not use generators, but i like your idea, very creative.though i don't see the practicality of this being used commercially, i think it would make a great solar promotional piece though! off-subject, it is time we stop looking at the upfront costs of things and start looking at what the long term costs are. most green-technology, although expensive at first, end up saving tons of resources and actually increase profits of businesses! studies show that people who work in a green building tend to be happier which benefits health, more excited to go to work due to the business's environmental ethics, are more productive because of natural lighting, and are more efficient because more work is getting done. green buildings can actually boost the efficiency of a business! thus saving tons of money and reducing tons of waste. Doesn't this just make sense to you?
- Q: Would it be possible to use a lens or a mirror to focus light onto a solar panel in order to make in more efficient? And is something like this already being used? It was just a thought and I haven't spent much time on it, but I figured I'd ask.
- yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
- Q: I am learning all about heat radiation in Physics. There is a question I am doing about Solar panels. It asks, why do glass covers improve the efficient of solar panels? I dont really understand. How do they?? thanks :D x
- For a solar thermal panel, the idea is to get the inside as hot as possible. There are three ways to lose heat - conduction, convection, and radiation. By cutting off airflow, the glass cover reduces cooling by convection.
