Q: Ok so i can have a problem i have two 5 watt 2 volt solar panels a 2 volt battery and a 400 watt ac 2 volt dc inverter i believe im only getting 5 watts from from my solar panels thats the equivalent of one is there any way i could get full voltage from my solar panels without theoretically burning my wallet.. please help
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q: i see these things all over the internet on how to make 'home made solar panels' but all of them require you to buy the solar cells and nothing tells you how to make your own. So how can you make your own solar cells?
I don't have an idea but would surely refer you to a website where you would surely find information on solar cells and many more alternative energy questions.
Q: How do solar panels affect the aesthetics of a building?
Solar panels can have both positive and negative effects on the aesthetics of a building. On one hand, they can enhance the visual appeal by adding a futuristic and environmentally friendly look. The sleek design of modern solar panels can be seen as an architectural statement, especially when integrated seamlessly into the building's design. On the other hand, some people may find the appearance of solar panels unattractive or incongruent with the building's overall design. However, advancements in solar technology are continually improving the aesthetics of panels, making them more appealing to a wider range of individuals. Ultimately, the impact on the aesthetics of a building depends on personal preferences and the specific design and placement of the solar panels.
Q: will at least consider them for their home electricity? I've seen several articles that new technologies are now being used, but it doesn't seem to be promoted to residential apps. I've even seen that the solar technology will be used in paints in the near future.
Solar panels are cost effective if they are used over their payback period. The problem is that the down payment is expensive, and the payback period is maybe 0-20 years, so very few people actually expect to own their homes for 0-20 years. It also only really makes sense in areas that buy back electricity generated during the day when you're not using it. In Germany and other european countries, power companies are required to buy back electricity at a higher price than they sell it for--this reduces the payback period and is a great incentive for solar panels. For this reason, they are much more popular over there. Given a little time for the price to fall and given some change in energy policy, solar panels will become more cost effective in the future. Depends on who gets elected, though. There is a solution to the payback period problem, though. Rather than homeowners taking on the long payback period in homes they may not own long enough, some companies are buying panels and leasing them to homeowners. In exchange, homeowners get reduced electric bills, that pay off the lease payments, plus a little extra. I think this is the way to go. check out the link below.
Q: If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?
If you pick the fuselage, look up friction stir welding. It's a low temp, solid state method of joining Al. I have taken a few classes (undergrad and grad) from Dr. Reynolds. This stuff is cool!
Q: in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
Some are better than others. It depends on the manufacturing technique. All will degrade over time, some over decades, others over months (if they're defective).
Q: How much space is needed to install solar panels?
The amount of space required to install solar panels depends on various factors such as the type of solar panels, their efficiency, and the energy needs of the property. Generally, a typical rooftop solar panel system requires about 100-400 square feet of space for every kilowatt (kW) of solar panels. Additionally, open areas or ground-mounted systems may require more substantial space. It is recommended to consult with a solar installation professional who can assess the specific requirements based on the location and energy goals.
Q: Can solar panels be installed on a small scale?
Yes, solar panels can be installed on a small scale. In fact, they are highly adaptable and can be installed on rooftops, balconies, or even small plots of land. This makes them a convenient and cost-effective solution for individuals or small businesses looking to generate their own renewable energy.
Q: i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.
A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3. - .8 electron volts, of the visible region as shown by ACEPT W3 Group (999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.
Q: Can solar panels be installed on mobile homes?
Yes, solar panels can be installed on mobile homes. In fact, mobile homes can be great candidates for solar panel installations due to their smaller size and affordability. Additionally, solar panels can help mobile homeowners save on electricity bills and reduce their carbon footprint.
