- Q: Solar panels which is the one produces the power...I wanna the complete description about it...
- This okorder for more detail.
- Q: Can solar panels be installed on a factory or manufacturing plant?
- Yes, solar panels can be installed on a factory or manufacturing plant. In fact, many industrial facilities are opting for solar panel installations to generate clean and renewable energy. The large roof spaces available in factories are particularly suitable for accommodating solar panels, which can help reduce electricity costs and carbon emissions while promoting sustainability.
- Q: How do solar panels affect the power grid?
- Solar panels can have both positive and negative effects on the power grid. On the positive side, when solar panels produce excess electricity, it can be fed back into the grid, increasing the overall supply of electricity. This can help reduce the demand on traditional power plants and decrease greenhouse gas emissions. However, the intermittent nature of solar power can also introduce challenges to the grid, as it can cause fluctuations in electricity supply. To mitigate this, grid operators need to carefully manage and balance the overall energy mix to ensure a stable and reliable power supply.
- Q: If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?
- As far as any albedo effects from solar panels, the entire USA only occupies a little over 2% of the worlds surface, if you painted the USA black, it would have a minimal effect on globally averaged temperatures. The mining of the resources alone required to cover the entire USA with solar panels would devastate the planets ecosystem. . .
- Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
- It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
- Q: Can solar panels be used for powering a theme park or amusement park?
- Yes, solar panels can definitely be used for powering a theme park or amusement park. Solar energy is a clean and renewable source of power that can effectively generate electricity for various operations within a park, such as lighting, rides, and even water heating systems. By utilizing solar panels, theme parks can significantly reduce their reliance on traditional fossil fuels, lower their carbon footprint, and contribute to a more sustainable and environmentally friendly operation.
- Q: When you consider that solar panels will not produce enough electricity in their service life to cover their cost should we subsidize them anyway? that much of the cost of a solar panel is the energy to manufacture, install, transport and maintain them. Shouldn't the market determine whether they are worth installing?Is subsidizing them taking money away from research that could be spent on more viable alternatives?Should we be taxed to pay for others solar panels when they don't work?
- Yes, okorder /... Bottom line is that government subsidies encourage people to buy solar panels, and make it possible for many who could otherwise not afford it. The more solar panels are purchased, the more the price will go down, and the more quickly the technology will be able to advance.
- Q: We are looking in to buy solar panels for our house. The payment has to be around or under $4000. Our house is a 4 bedroom and 3 bath 2-story house. (Around 2500 sq. ft.) Where can we get the solar panels? Also: Will it heat our water? When we get the solar panels, what direction do they have to be facing?
- The crisis is that it's so high priced to have mounted and as you assert it's going to take decades earlier than you honestly begin saving above what the install rate used to be, I for my part might now not cross forward and make that kind of funding, it might be extra lucrative to hold the cash in a constructing society, get the curiosity from it and use that to pay to your electrical energy however the important factor that I have towards sun Panels is that until you keep in that condo for a minimum of twenty 5 years you'll now not succeed in the factor in which you're saving and to capitalise on it you might need to keep there for decades extra, so you'll now not have the choice of relocating condo with out wasting your funding and on the second having sun panels does now not develop the significance of the estate, it's only a well promoting factor, while you purchase your new condo, you might commonly need to begin everywhere once more after which given that of the years will on no account reside lengthy ample to obtain any improvement from it.
- Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
- see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
- Q: I'm very interested in how solar panels work. I understand the bigger picture of how it can be used for solar heating or as a generator, but I'm lost at the smaller details. Things like: - Could my computer work on solar? It has a 900 watt power supply (this is excluding monitor/speakers) - if a panel is for example, a 60 watt panel, does this mean it will pump 60 watts a second into a battery? - Does solar heating make the water electrified?
- solar heating will not make the water electrified,solar energy be converted into heat energy which will heat water,there is no electricity but heat energy to make water hot,you will not worry danger of electricity leakage.
