Q:. Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?

Q:When you add a load resistor to a PV panel (Solar panel) of 00 ohms what happens to the voltage produced from the cellAlso, as the resistance increases, how does this affect the output voltage

Q:I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.
Q:Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.
if they get energy from burning coal, they will be destroying our atmosphere. if they use solar panels, they can use natural energy from the sun without harming the environment.
Q:Can solar panels be installed on agricultural or farming operations?
Yes, solar panels can be installed on agricultural or farming operations. In fact, they are increasingly being adopted in these settings to generate clean and renewable energy. Solar panels can be installed on rooftops of barns, sheds, or other structures, as well as on open fields or unused land. By harnessing solar energy, farmers can reduce their electricity costs, lower their carbon footprint, and contribute to a more sustainable farming practice. Additionally, solar panels can provide shading for livestock or crops, minimizing heat stress and improving overall farm productivity.
Q:Is it really necessary to make solar panels that expensive?
First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
Q:Any recommendation for best solar panels?
I have 3 ARCO solar panels and a wind generator on the Boat and it's all I need to live comfortably on 2 volts.
Q:What is the impact of roof pitch on solar panels' efficiency?
The impact of roof pitch on solar panels' efficiency is significant. The pitch, or angle, of a roof determines how much direct sunlight the panels receive and how effectively they can convert that sunlight into electricity. In general, a roof with a steeper pitch allows for better solar panel performance as it maximizes exposure to sunlight and minimizes shading. However, if the roof pitch is too steep, it can increase wind resistance and make installation more challenging. Therefore, it is crucial to find the optimal balance between roof pitch and solar panel efficiency to ensure optimal energy production.
Q:how to make a solar panel without buying any kit?Any things at home that can be used for solar panels(what are they?)procedures how to make a solar panel
