- Q:Can solar panels be used in areas with high winds?
- Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panel installations are properly designed and anchored to withstand the wind speeds typical for the area. Additionally, selecting durable and wind-resistant panel models can help mitigate any potential damage caused by strong winds.
- Q:Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.
- There are RV solar panels but they are mostly for extending the life of the batteries, you should still bring a generator. There are marine solar panels and wind turbines which are larger but many sailing yachts are larger too.
- 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:I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
- Q:How do solar panels affect the property's energy efficiency rating?
- Solar panels can significantly improve a property's energy efficiency rating by generating clean and renewable electricity. As they harness the power of the sun, solar panels reduce reliance on traditional energy sources, resulting in lower energy consumption and reduced greenhouse gas emissions. This increased energy efficiency positively impacts the property's overall energy performance and can potentially lead to improved ratings and lower utility bills.
- Q:Can solar panels be damaged by hail or extreme weather?
- Yes, solar panels can be damaged by hail or extreme weather. Hailstorms with large-sized hailstones can cause physical damage to the solar panels, such as cracks or shattered glass. Extreme weather events like strong winds, heavy snowfall, or storms can also potentially damage the panels or dislodge them from their mounts. It is important to ensure proper installation and employ protective measures, such as using hail-resistant materials or installing panels at appropriate angles, to minimize the risk of damage.
- Q:Can solar panels be installed on a pergola or awning?
- Yes, solar panels can be installed on a pergola or awning. In fact, they can be a great option for maximizing solar energy production while providing shade and protection from the elements.
- Q:What are the different types of solar panels?
- There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are made from a single crystal structure, making them highly efficient but also more expensive. Polycrystalline panels are made from multiple crystal structures, offering a slightly lower efficiency but a more affordable price. Thin-film panels are made by depositing a thin layer of semiconductor material onto a substrate, making them flexible and lightweight, but with lower efficiency compared to crystalline panels.
- Q:How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
- Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
- Q:I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.
- definite, the inverter ought to pull potential from both the battery and photo voltaic array, yet so what? that would favor to not be a project. both the potential from the photo voltaic array receives kept contained in the battery, or it is going on to the inverter, what vast difference does it make? in reality that's more beneficial effective to pass on to the inverter, as battery value/discharge cycles waste quite some potential. yet you desire a fee controller between the panel and the battery and which will regulate the present into the battery to maintain away from overcharging, and also regulate the voltage and contemporary to right value the battery. without it, the output from the array will be too intense for the battery, or too low. .
