Q:stationary solar panel project?
Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
Q:Solar panels for car fans?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
Q:2 Questions on Solar Panels?
The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.
Q:How does solar panels work?
Q:How do solar panel power systems work?
The panels soak up the energy from the sun and then convert the energy into power, electricity, etc. They can also store a lot of energy so that we still have power on cloudy days. Does that help? Without more info, its hard to get more specific.
Q:its about solar panels?
It depends on what you want to do with the solar panels, Heat your water , heat a pool or spa, or to make electricity to use instead of that supplied by the power company. The first three are fairly easy and straight forward. Depending on the amount of water that needs to be heated, the location you live at in relation to the equator and the location of the solar panels and piping . The panels for this applicatin are 00s of feet of piping that absorbs heat from the sun and circlate it. The panels them selves are sort of inert and can be very heavy when filled with water.. Makeing usable power to replace the power company is a real problem because among other things solar cells create DC voltage. A house runs on AC voltage. So all of the items to heat water still apply, location, placement, etc. But now we have to figure hrs of sunlight the output of the cells running the power to a transformer to transform the voltage from 2 volts DC to 20 volts DC and then running the power thru a converter to change it from DC to AC at each point ( transformer converter ) there is a loss of power do to a change in current. After all of the above if a cloud comes by your power will stop, and at night you will have no power. The fix for that is storage cells AKA batteries which store the power until you need it, like night time. The glamor of a all solar powered home is great,, but it isn't practical. So What to do, You eliminate the battery storage, and also hooking up the power to your home. You feed it right into the power companys wiring and guess what? The electric meter on you house runs back wards your send more power to them during off peak times that your using. For every dollar the meter runs backward you get a free dollars worth when you need it. This is a way of storing the power as credit with the power company instead of batteries Its a lot to understand and I hope I helped
Q:What is the most powerful solar panel made?
Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.
Q:Feedback on Solar Panels?
Our solar electric system has been up for 5 years now. No trouble so far, and output has not diminished noticeably. They have survived gale-force winds (gusting to 00 mph) without loosening. If I installed the same system today, it would have been half the cost for the same power, and smaller, too. Can't say I have any regrets. It keeps up with our yearly electricity demand, but we live in a mild climate. We only turned on our heat today, and have no A/C in the summer.
