Q:solar panels vs (organic) plants?
Depends on the planet and solar panel. Generally, solar panels are more efficient according to these figures I bumped into. Photosynthetic efficiencies range from 0.% - 8%!
Q:Can I made my own solar panel?
no, not really, they require exotic chemicals and processes. The online outfits that promise to help you build your own are mostly scams. The one I looked at (other answer) seems to just be an assembly guide to put together solar cells into panels. That is fine, but you still have to buy the solar cells, the expensive part. The assembly is just putting them in series/parallel to produce higher voltages and currents. .
Q:Homemade Solar Panels?
The technologies of the photograph voltaic panels is a lot previous any DIY undertaking. you ought to purchase pre-assembled panels and set up them, yet you in addition to mght choose the units to make the DC they generate into the AC your place desires. additionally you will choose the batteries for the nights and the cases while the solar does not shine. photograph voltaic/ photograph voltaic technology does artwork yet isn't a miles less high priced thank you to decrease your reliance on the electrical powered grid as of this time. They fee 2 hands and a leg, and take some years yet to come back on the brink of wreck even on the electrical powered mark downs. Do a seek on the quantity of skill each and every panel will generate and then compute how lots skill you like and what the expenditures are. i think in photograph voltaic skill, yet no longer for somebody place of abode is it sensible. stable success.
Q:Is it worth installing solar panels on a house that has no South-facing roof?
Depends how much sun you get. Even if you don't face south, you could still be able to harvest a lot of energy from the sun. You could install panels transversely so they face south to increase sun exposure, but this might not look so nice. Or you could move your house to the Southern hemisphere, when your solar panels should face north. Or install miniature windmills on your roof instead.
Q:Solar panels for home info?
I am a solar consultant within the state of South Carolina. I can answer questions and provide you with links that may help in decision making. Let me know.
Q:Does anyone know a company that will make custom solar panels?
okorder.com Other sources available on the first Link also. Wingman
Q:Where are solar panels used?
Solar panels can be used anywhere in the world. The only requirement is that there is sufficient sunlight to power the solar panels and in many developing countries, solar energy is used to heat water.
Q:where can i get a small solar panel to power an outdoor water pump?
Home Depot has several sizes for applications such as yours in the gardening section. Because I am always looking for ways to save money, even in the long run, I was looking at the possibility of solar power for here in SW FL.
Q:Solar Panel load resistors?
Photovoltaic cells have a load curve that gives the power conversion based on the current drawn. This makes it harder to calculate. For instance, at infinite resistance, the solar cell will have a peak voltage that produces no power (P=I*V=V^2/r). At short circuit, the voltage collapses to essentially nothing and so the power is almost nothing. There is an optimal load (sweet spot) where the resistance applied will draw the most power out of the cell while not overloading it. This measure is either given by the manufacturer or found experimentally. Upon taking a lit panel that has no load and applying a 00 ohm resistance, the voltage will drop. By how much is entirely dependent on the array layout and specific cell characteristics. As the resistance drops from the optimal load point, the voltage collapses fairly sharply. As the resistance increases from the optimal load point, the voltage will rise more at first and then level off to the peak or no-load voltage.
Q:Solar Panel System at Harbor Freight?
I would not buy Harbor Freights Chinese made Solar kits-I tried one and don't think it produces enough power to run a flashlite
