Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q: What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
Let me help you get an idea of what you are talking about as your notes seems a bit jumbled. Mostly when they refer to a silicon solar cell they mean that the silicon is one crystal of silicon. (very much like a diamond, but with atoms of silicon instead of carbon). A single perfect crystal of silicon can be grown that is very large at temperatures near the melting point of silicon or around 400C and then is sawed up to create electronics or solor cells. Polycrystalline :) solar cells are also made of silicon, but instead of a single crystal it is made of a jumble of small crystals that have different sizes and directions. So these types of solar cells can be made using a silicon gas (siline: SiH4) at much lower temperatures 600-700C. So these are less expensive to make, but because they are not perfect crystals a poly solar panel that is the same size as a crystalline solar panel will make less energy. I hope that helps.
Q: What is the impact of dust and dirt on solar panels' efficiency?
Dust and dirt on solar panels can significantly reduce their efficiency. When these particles accumulate on the surface of the panels, they block sunlight from reaching the photovoltaic cells, resulting in decreased energy production. Regular cleaning and maintenance of solar panels are crucial to ensure optimal performance and maximize their power output.
Q: I paid for an appraisal and the home was valued at $25,000. The problem I have with this is my house is equipped with solar panels. I paid about $25000 for them. A comparable house sold for $225,000 4 months ago. Same amount of rooms, bathrooms, square feet, lot size and curb appeal (landscaping). But no solar panels. Home prices in my neighborhood have also gone up. I would like to know if there is any way I can dispute this as I feel I just wasted a lot of money on a incorrect appraisal.
You haven 't done your research. Solar panels reduce the value of a home. If you do own them outright, instead of renting them with a contract, be sure that the appraiser knew it or knows it now. It may not change the appraisal amount. If you are renting, the value will be worse. Nobody will buy a house and pay you for the contract you signed - for renting them.
Q: How do solar panels connect to the electrical grid?
Solar panels connect to the electrical grid through an inverter, which converts the direct current (DC) generated by the panels into alternating current (AC) that is compatible with the grid. This AC power is then fed into the main electrical panel of the building and can be used to power appliances and devices. If the solar panels generate excess electricity, it can be sent back to the grid, and if there is a shortfall, electricity can be drawn from the grid to meet the demand.
Q: Can solar panels be installed on historic buildings?
Yes, solar panels can be installed on historic buildings. However, the installation process needs to be carefully planned and executed to ensure that it does not damage the historic fabric or compromise the architectural integrity of the building.
Q: Can solar panels be installed in areas prone to hurricanes or tornadoes?
Yes, solar panels can be installed in areas prone to hurricanes or tornadoes. However, additional precautions and engineering considerations need to be taken to ensure their durability and resistance against strong winds and potential impact from debris. This can include using reinforced mounting systems, implementing proper anchoring techniques, and selecting panels that meet stringent wind load requirements.
Q: I mean when light hits the solar panel where does the energy go and what does it become? Be specific.
I think you got half the answer, but basically like everyone else said, the light hits the electrons and create energy now that energy, since it is now an electrical energy is then saved within batteries connected to the solar panel and that provides the power itself, so as long as there is sun, the batteries will charge up, once the sun goes away, the batteries slowly deplete, but once the sun hits, more energy. =)
Q: Can solar panels be installed on a warehouse or storage facility?
Yes, solar panels can be installed on a warehouse or storage facility. In fact, warehouses and storage facilities are often ideal locations for solar panel installations due to their large, flat rooftops and ample space for arrays. Installing solar panels can help these facilities reduce their electricity bills, lower their carbon footprint, and even generate additional income through various incentive programs.
