Q: Is there a cheaper way on how to make your own solar panels ? Can someone share their real life experience ? Thank you.
It used to be possible to get broken solar cells for free from solar cell and solar panel manufacturers and then it's just a matter of labouriously measuring the voltage and current characteristics of each fragment and soldering them in a combination of parallel and in series to get a crude solar panel with the desired output but the manufacturers have caught on and now sell the broken fragments by the pound so it's not really a cheap solar panel anymore but it's still very labor intensive and results in a fragile solar panel that is readily damaged and quickly degrades. Not really worth the trouble any more.
Q: Can solar panels be installed in a remote location?
Yes, solar panels can be installed in a remote location. In fact, remote locations with abundant sunlight can be ideal for solar panel installations as they can generate electricity even without access to a traditional power grid. The advancements in solar technology and the ability to store excess energy in batteries make it easier to set up and maintain solar systems in remote areas.
Q: How much electricity can a solar panel produce?
The amount of electricity a solar panel can produce depends on various factors such as the size and efficiency of the panel, the amount of sunlight it receives, and the location. On average, a standard solar panel can produce anywhere between 250 to 400 watts of electricity per hour.
Q: Is it really necessary to make solar panels that expensive?
I think it will cost about %0 Million US for a 50 Mega Watt Factory
Q: If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?
all depend to the surface of your solar panel
Q: Can someone tell me if I can run a air conditioner off solar panel?I have a ET-P65420 20Wp solar panel. What do I need to make it work? I am told I will need a Enphase Energy Microinverter M20. Is that true? I am looking to run a 5000 to 8000btu air conditioner to a max of 0000btu air conditioner. I need to cool a 0x30 space. One time I read, I need total watts of panel to match total watts of air conditioner. Then I read, that I do not and can run more watts then what the panel is depending on the inverter and batteries.Can someone tell me what and how to make this work please? More panes or inverter and batteries?
You can expect such an air conditioner to use something like 500 - 800 watts of power. The ET-P65420 20Wp solar panel produces at most 20 watts so you will need at least three of them. Since solar cells make DC (Direct Current) electricity, and air conditioners use Alternating Current (AC) electricity, you do need an inverter. The M20 is a 220 volt inverter, and I suspect you are looking at a window air conditioner that will probably use 0 volt power. And the M20 only puts out a maximum of 240 watts so you need one for each of the 3 or more solar panels you will have to use. So the first thing to do is shop for air conditioners, getting the most energy efficient model you can find, paying close attention to the voltage and wattage ratings in the owner's manual or on the UL label on the back. Say it is a 500 watt, 0V unit. You will need three solar panels and three 0 volt model inverters. Also note that the 20 watt rating of the solar panels if when the panel is facing DIRECTLY at the Sun. If you just lay them on the roof, then even if the roof is sloped at a good angle (30 degrees) and facing south, it will only produce the maximum power around noon. 4 hours before noon, unless to go up there and tip them up to face the morning Sun they will probably produce only about half that amount of power. So right there you either need a motorized mount to automatically follow the Sun or twice as many panels. However, if you are going to connect the solar panel(s) into the house power, so that it(they) merely supplement the power company power, then you can use any amount of panels, and the power company will supply whatever extra power you need. That requires a licensed electrician to do. Or if you want to just power the air conditioner directly from the solar panels without any interconnection to the house power, then you need to know a lot more about electricity that you appear to know.
Q: Can solar panels be used in areas with high temperatures?
Yes, solar panels can be used in areas with high temperatures. In fact, solar panels are designed to withstand a wide range of environmental conditions, including high temperatures. However, it's important to note that extreme heat can slightly reduce the efficiency of solar panels, but this reduction is usually minimal and does not significantly impact their overall performance. Additionally, proper installation and maintenance can help mitigate any potential heat-related issues.
Q: Can solar panels be used in agriculture?
Yes, solar panels can be used in agriculture. They can provide electricity for irrigation systems, power farm equipment, and greenhouse lighting, among other applications. Additionally, solar panels can help reduce farmers' reliance on fossil fuels and contribute to a more sustainable farming practice.
Q: China is building solar panels and have been for years. That is the most abundant energy in the world. My nieghbor has two panels on his roof and he actually sells energy back to the electric company. These panels cost about $30,000. each, because we don't produce them here on that level.If we did, that price would drop drastically. Other alternatives are also available. Drilling for oil will no change anything. Once you give the oil companie the go ahead, the will focus on that and the alternatives won't be developed any farther. We will be right back here in about 0 years. The price will not go down anyway. So why not switch half of our fuel to alternatives?
I know for a fact that -China has a lot of Nuclear Bombs pointing at the US--- paid for by Wal-Mart
Q: I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
An 300W inverter will draw 25 amps from a car battery but the solar panel will only produce about 4 amps. By drawing too much power with the inverter you lowered the voltage so much in the panels wiring that the amp rating on the internal wiring was exceeded and they melted. Next, time run the panel to a voltage regulator, then the regulator to a car battery, then the battery to the inverter.
