- Q: What is the difference between monocrystalline and polycrystalline solar panels?
- Monocrystalline solar panels are made from a single crystal structure, typically silicon, which results in a uniform appearance and higher efficiency. Polycrystalline solar panels, on the other hand, are made from multiple silicon fragments, resulting in a less uniform appearance and slightly lower efficiency.
- Q: Can solar panels be used in conjunction with wind turbines?
- Yes, solar panels can be used in conjunction with wind turbines. This combination of renewable energy sources is known as a hybrid system and can provide a more reliable and consistent electricity generation. By utilizing both solar and wind power, the system can generate electricity during both day and night, as well as during varying weather conditions. This integration allows for a more efficient and sustainable energy production.
- Q: How can I start working as a solar panel installer/technician without years of education?
- The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.
- Q: hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!
- There's no standard nuclear reactor, but if we take a GW nuclear plant, it can generate about 8 terawatt-hours/year. A 200 watt solar panel can generate about kilowatt- hour/day, or 365 kwh/year, so that's about 2 million 200 watt solar panels. However, the power output from the nuclear plant is controllable by the operators, where solar panels only operate at full output for a few hours/day (on clear days - less if there's cloud). Therefore, to compare the two, you have to factor in some kind of energy storage or backup which will increase the cost of the solar installation (perhaps by a factor of two or more). Despite claims of solar being cheaper than coal now, when one compares apples to apples (i. e. total energy produced, and controllability) solar is still several times more expensive than coal, and about twice as expensive as nuclear even in the U. S. A gram of U-235 can make usable energy equal to three metric tons of coal. Solar energy production has no hazardous by-products, but manufacture of the panels can involve some very hazardous materials like fluorine (for silicon panels) or cadmium (for CdTe panels). This is part of the reason panel manufacture has gone to Asia - they have fewer environmental regulations and it's easier to dispose of the byproducts of production. DK
- Q: I want to get a solar panel to run a fan (or two) for swamp coolers.I'm not looking to power 20box fans, just maybe some of those auto fans.What the heck kind of panel do I need? What is a power inverter and what does it do?Will I lose all my power if I use a 00' extension cord?How do I choose what I'm going to need?
- Any fan you find in a store is going to expect AC, not DC, which is what solar panels produce. An inverter changes DC to AC. You'll probably want a deep cycle car battery to smooth out overages and underages. Any fan will tell you how many watts it uses. Panels should (i haven't looked) tell you how many watts they produce. Just off hand, I'd guess you're looking at a 2'x4' panel. Considering how much you'll be paying for the rest of the stuff, a good 00' cord is appropriate,. Last, it's worth the experience, but you'll never recover the cost of everything that you'll have to buy. Have fun.
- Q: Can solar panels be installed on a library or educational institution?
- Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions have already embraced solar energy and installed solar panels on their rooftops or surrounding areas. This helps them reduce their carbon footprint, save on electricity bills, and serve as a sustainable example for the community.
- Q: How do solar panels affect roof ventilation?
- Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat absorption and helping to keep the attic space cooler. This can decrease the need for excessive ventilation and potentially lead to energy savings. However, solar panels can also obstruct the airflow on the roof, limiting the natural ventilation and potentially causing heat buildup. Therefore, it is important to consider the design and placement of solar panels to ensure proper roof ventilation is maintained.
- Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q: if you know the area of the panel can u calculate for the wattage or voltage of the panel..
- You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
- Q: Okay, me and my friends are going to fix up an old trailer that's out in the woods, we want something to be able to run small electric appliances off of, but it's to far to run power to. How can we make a good but cheap homemade solar panel that we could plug things into? The trailer is in more of a field so it gets plenty of sunlight! Thanks for any help! :)
- you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself
