Q:Chem question regarding using solar panels ....?
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:Solar Panels in the 200 Toyota Prius?
Hi, the solar powered-venting system is not air conditioning, it is simply a venting system to attempt to balance the interior temperature of the Prius with the outside temp when the interior of the Prius is at least 68 degrees. This is an optional system and is available as a stand-alone option for $800.00 or $3600.00 in conjunction with the navigation system. The solar roof is integrated into a full function sunroof, but the sunroof can be opened without using the solar venting portion. There is a separate portion of the system that will allow the driver to turn on the electric AC for three minutes, if there is enough stored charge in the nickel metal hydride (NiMH) hybrid battery. The AC is not linked to the lead acid battery, and is run by the NiMH only, not the gas engine. The NiMH and lead acid are two separate power systems. The solar panels do not power anything else in the Prius and do not boost the power to any of the systems. The solar venting does permit less energy from the NiMH to be utilized for AC at the next startup. For trivia, the EPA will not allow Toyota to install the solar venting system on Prius with the top package V (#5). The EPA feels the Prius is too top heavy with all the additional sensors required for the radar guided cruise control and all the other high tech components in the top end option package, just FYI.
Q:Hi trying to learn more about Solar panels!?
solar panels collect the suns energy and turns that into electricity that is then stored in batteries. attached to the batteries is another device that takes the power from the batteries and turns it into power you can use in your house. it is a very expensive power alternative.
Q:Do solar panels float?
With the Oceans rising as fast as they are, I hope so. LOL
Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:45 Watt Solar Panel -?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:Solar panel placement idea?
The MOST efficient placement is on a motorized mounting that constantly moves it to face the Sun directly. Almost nobody does that because it is clumsy and expensive. The best fixed position is facing X degrees due south of straight up, where X is your latitude. I am in Austin, at about 30 degrees latitude, so on the south side of a 30 degree pitched roof would be ideal. The direct south facing it the best average to catch morning and afternoon sun, with most efficient pointing at noon. The tilt equal to latitude is the best average between the high Sun in summer and low Sun in winter, with most efficient pointing in spring and fall.
Q:Solar Panel questions...?
Just think about it and don't do it unless Ontario and the Utility companies give a huge rebate. Forget tax credits. Solar voltaic panels generate electricity...it will take more than 20 years to break even...assuming they last that long. Solar panels that generate hot water may be OK but will take about 0 years for a payback.
Q:I would like some info on Solar panels and Wind Generators...please?
Toronto would not be higth on my list of solar panel worthy locales. They are a bit pricey and are only cost effective in climates and locations with lots of direct sunlight. But if you could safely say you get direct light on your rood nearly every day, they could work. Wind turbines are getting better... especially omnidirectional dome type turbines. But again they are a bit costly, and work best if you believe you get direct wind for at least half the day. If your roof is reasonably flat and structurally sound, a solar hot water generator can be quite cost effective. Essentially it is a panel of corrugated metal under two thin transparencies of plastic. Water is pumped up to it and as it runs along the corrugation, the trapped heat under the plastic heats it up nicely. They are cheap to buy and easy to build and install, and will completely remove the need for a dedicated hot water heating system. Once again, it really depends on the precise location and construction of your house. Do a search for solar heat in your area. If it is cost effective, someone will be offering...
Q:Is heat a factor in how much energy is gained when using solar panels?
no only the sunlight is used in generating electricity
