Solar panel working process
In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.
Specification of Solar Monocrystalline Series
- Optimal permutation on solar cells to keep enough heat diffusion, decreases hot spot effect.
- High quality and anti-ageing EVA, weather resistance backside raw materials assure reliable solar panels.
- Passed 5400Pa mechanical loads testing by UL, can withstand bad and high mechanical load working environment.
- With good sealed performance, moisture resistant, aging resistance, high/low temperature resistant, the inner terminals of our junction box owns good electrical performance transmission. Bypass diodes used can avoide hot spot effect and damages to panels. Output cables and mating connectors are safe and reliable for installation application. Adopt weather resistance, sealed, good sticky silica gel when assembling.
- Strict quality inspection on each procedure and 100% electrical performance test to meet power requirements.
- 0~+3% power tolerance.

- Q: Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- Taken at face value, it would take about 55 hours to re-charge a dead flat battery. However, you don't get 24hrs/day sunlight. Even worse, the output from a panel is only maximum when the sun is at 90 degrees to the surface. Let's assume you can find some way to track the sun. No battery should be allowed to discharge below about 50% so we can halve the recharge time. I would say about 4 days.
- Q: Are there any free classes to learn about solar energy and building a solar panel

- Q: Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.

- Q: What is the role of inverters in solar panel systems?
- The role of inverters in solar panel systems is to convert the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity that can be used to power household appliances and feed into the electrical grid.
- Q: Can solar panels be installed on a church or religious building?
- Yes, solar panels can be installed on a church or religious building. In fact, many religious institutions are increasingly adopting solar energy as a sustainable and environmentally-friendly solution. Installing solar panels on a church or religious building can help reduce energy costs, lower carbon footprint, and demonstrate a commitment to green practices.
- Q: I want to get definate instructions on how to make the components and convert my home to solar energy. I know I could hire some one to do this, but frankly I do not have the funds at my disposal to do it. I thought if I could find detailed instuctions I could slowly do it myself (with my husband's help). I have looked into loans for this purpose to no avail. Finding the information on the net could take forever! If anyone knows a site that would give me the information or even a hint on how to start? Any help will be appreciated, but if you have any good links to good information please share them with me..Thanks
- Typical solar panels like Engineer describes require a lot of space. A single panel may only light a single light bulb. You may want to look into a different way of generating electricity with solar, it doesn't use a cell to turn the sunlight into electricity, instead it uses mirrors to focus the sunlight onto a pipe between the mirrors. The heat causes water or another liquid in the pipe to boil and the steam created turns a turbine that produces the electricity. It has the potential to be less high-tech, more forgiving of minor design and structural problems and more affordable. I don't know of any system that is privately available but you can get more info at the link below. They're building a full test facility in Nevada right now. You could presumably cobble something like this up on your own.
- Q: OK so how do these solar panels supplement the AC from the grid? Like do they invert the output of the solar panels and sync two AC sources together? If so how and with what? Or do they convert the AC from the grid to DC and then supplement and then invert it? If so how and with what? Thanks

- Q: How do solar panels affect roof weight load?
- Solar panels can increase the weight load on a roof, but modern solar panel systems are designed to distribute the weight evenly and not exceed the load capacity of the roof.
- Q: How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
- The cost of solar is measured in dollars per watt. That means the cost of a cell that can make one watt continuously in full sunlight. A friend of mine is starting a new job to set up a new solar cell factory and he said the present cost is $3 per watt, but that they expect to get that down to $ per watt in a few years. They can be damaged by weather, just like any regular roof. My insurance agent asked if I had solar panels, so it is a factor in insurance cost. I never heard of recycling or disposing of old panels, maybe because they are so new and last so long that not many are ready to be disposed of yet.
- Q: Can solar panels be used for powering a hotel or hospitality establishment?
- Yes, solar panels can definitely be used for powering a hotel or hospitality establishment. Solar energy is a clean and sustainable source of power, and installing solar panels can significantly reduce energy costs for the establishment. Additionally, hotels often have large rooftops or open spaces that are suitable for installing solar panels, making it a practical and efficient solution for meeting their energy needs.
