Q:how much do solar panels cost?
The okorder.com
Q:have you ever installed solar panels for your home?
yes. Its pretty simple connection. It does save money on electricity.
Q:Why are solar panels still so expensive?
materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
I would like to go with commercial grade solar panels.
Q:how often do you have to replace solar panels?
Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.
Q:What are solar panels?
Solar panels are a collection of photovoltaic cells, that are used to generate electricity, from light. Here is the simple explanation from wikipedia, concerning photovoltaic cells . Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. 2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel. 3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity. Solar panels are used extensively for power generation in many places, but most space applications (like satellites and spacecraft) use solar panels. If you look at a picture of the current configuration of the International Space Station, the giant wing things are the solar panels.
Q:What can a watt solar panel power?
New Mexico is a good area for solar. Unfortunately, solar electric panels generally don't save money over grid electricity until the installed system is large - like, 000 watts or more, 4000 watts being a common size. This costs many thousands of dollars up front, which hopefully are paid back over the years in electricity savings. There are a couple other things to look into, though. The first is conservation and efficiency. If you can shade and insulate your house so that the air conditioner doesn't run so much, that can pay for itself in a year. Also, NM is an excellent place for a solar water heater. Call a solar installer to see how much it would cost. That would pay back in a few years, with a much smaller investment than solar electric.
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:Solar Panel info needed?
A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
There is an abundance of free energy available on this planet. Wave, wind, solar, (underground), and many many others that I can't remember right now. If some of the multi-trillions currently being spent being spent by the US government on defence (and the rest of the planet defending ourselves FROM the US) were re-directed towards exploiting sustainable, long-term energy supplies, then much work would be generated and the cost of energy would drop significantly - in the long run. So, why are we not utilizing these sources of energy? Unbelievably short-sighted right-wing political ideology, that's why! One thing almost never reported about nuclear power, is that there isn't much nuclear power fuel available on this planet. I think I can quite honestly state that when the time comes when we are forced to move from non-renewable to renewable energy production, it will probably be far too late with far too much damage done and the environment will collapse and become incapable of supporting oxygen breathing life-forms. I concluded many years ago that capitalism will probably end all life on this planet one day. Capitalism IS right-wing politics! Do you now see where the problem is coming from?
