Q:This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ,thank you!!
Likely there will be at least a small change in the no load volts. The short circuit current will be different and the watts output will be different. Connect an amp- meter to the panel with or without a to 00 ohm resistor in series with the amp-meter and you will see different amounts of current for different colors. You do however need to adjust for the amount of light falling on your solar panel. Possibly you can use a exposure meter or a bolo meter as reference. Neil
Q:Me and my friend have made our own functional solar panels for considerably less than retail prices and we are thinking about selling them. Are there any legal issues regarding this? Would I need any special licenses or anything? Would using brand name components or parts in the panels make any difference legally? I want to know before I just go out and start doing it. Thanks!
Would those be heating panels, or electric panels? If the latter, you would not have any safety certifications (I assume), so the panels would be illegal to use for a serious, grid-tied system. You would need to make this clear to your customers, that they could only connect to stand-alone systems. If this is in the US, there is always some finite danger of lawsuits if your product is defective. If the water heater leaks or blows up on someone's roof, you might have to go to court to defend yourselves. Even if you disclaim all warranties, in some states, if you sell something as a water heater then it has to heat water reasonably, and also not be hazardous. In other words, fit for its purpose. Check your local laws.
Q:I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?

However, a brand does not really matter for solar or wind power. Most of them comes after the testing done by the government. Also if you can find local electrician to suggest how to get second hand panels for your house would be even better...
Q:I am looking to get some solar panels for my home to just power a few lights, a fan or two. I have a generator but I want that only to power the fridge and maybe some other small stuff for convenience.But mainly want the solar panels for the lights and fans. Any one have an idea of how about I go to figuring this all out? Should I call a contractor or anything?
If your only deed is for power during outages, solar is not the way to go. You can add up all the wattages of the fridge and the lights you want to use, and see if the total is less than the capacity of the generator. If it is more, buying a larger generator is the answer. You can find the wattage of the fridge on the inside, or back. If not, Google the model number and manufacturer. You may already use CFL light bulbs, but if not, they can help reduce the load.
Q:Can solar panels be used in areas with high pollution?
Yes, solar panels can still be used in areas with high pollution. While pollution can reduce their efficiency to some extent, solar panels can still generate electricity even in polluted areas. However, it is important to note that excessive pollution may result in a decrease in their overall performance and require more frequent maintenance to keep them clean and functioning optimally.
Q:okay so im lookin 4 an article which explains how practical, wokable, feasible solar panels are. only positive points please :) give me the link. PLZ HELP!!!!
photograph voltaic panels are as powerful by means of fact the area helps. working example, I checked into photograph voltaic panels for my domicile in northern Indiana and found out that they are very ineffective right here by means of fact we've cloud conceal over 60% of the twelve months. regardless of the some temperture base if we've been in simple terms on the different fringe of Lake Michigan the comparable panels could be greater powerful. My analyze has shown that wind power is lots greater powerful. we attempt to get a zoning variance so as that we can deploy a windmill. in view that your venture is for eco-friendly, undergo in concepts that each and all of the timber used would desire to be bamboo, as that's the main sustainable timber source.
Q:Can solar panels be installed on a theme park or amusement park?
Yes, solar panels can be installed on a theme park or amusement park. In fact, many theme parks around the world have already installed solar panels to generate clean and renewable energy. This not only helps to reduce their carbon footprint and dependence on fossil fuels but also saves them money on electricity bills in the long run. Additionally, solar panels can be integrated into the design of the park, complementing its aesthetic appeal and showcasing the park's commitment to sustainability.
Q:I have a 2V .5W solar panel and I want to get a battery that can be charged by the solar panel that can then be used to power a 2V .5W fan. Ideally I want all the components to be connected and able to run without interaction. I have very little knowledge in regards to this field which is why I have come to yahoo answers. Any help would be greatly appreciated.

Q:Can solar panels be installed on convention centers or event venues?
Yes, solar panels can be installed on convention centers or event venues. In fact, many convention centers and event venues have already started adopting solar energy systems to reduce their environmental impact and save on energy costs. The large rooftop spaces available in these venues provide ample opportunity for installing solar panels and generating clean, renewable electricity.
Q:What is the impact of roof age on solar panels' efficiency?
The impact of roof age on solar panels' efficiency can vary. Older roofs may have structural issues that could affect the installation and performance of solar panels. Additionally, older roofs may require repairs or replacement in the near future, which could lead to the need for temporarily removing and reinstalling the solar panels. However, if the roof is well-maintained and structurally sound, the age alone may not significantly impact the efficiency of the solar panels. It is important to assess the condition of the roof and consult with a solar professional to determine the best course of action.
