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.

- Q: . The 2v battery will only be turning a small 2v motor that will be turning very slowly yet possibly or a long time. 2. -2 hours max per day it will be running3. I want it to be fully sufficient on solar power once the energy in the battery runs out. What specifications for my panel do you think I will need. However, i have limited space so the smaller the better as long as it can do the jobP.S: I don't know much about electricity and solar power so simple answers please :)
- batteries are rated with the help of the CCA, chilly cranking Amps the better the CCa the longer it is going to very last, don,t imagine you want a charge Controller as your consistently drawing juice from it, the picture voltaic panel will keep the bat at its height , then even as the solar is down , the pump will draw off the bat,
- Q: if u buy solar panels and never take em out of the box for like thirty years will they still work good thirty years after you bought them
- They should do fine.
- Q: if car companies install solar panels on cars, like in all the car were the sun can reach that would reduce the consumption of gas in the summer, and might save some energy for winter and if that energy is not enough they can use gas or electricity i think that would be a lot of savings, and less contamination i don't know that is my idea what do you people think?
- Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
- Q: i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .
- The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
- Q: How much sunlight is needed for solar panels to work?
- Solar panels can work with any amount of sunlight, but they are most efficient when exposed to direct sunlight for at least 5-6 hours per day.
- Q: How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please)

- Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?
- The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
- Q: trees vs solar panels who would win?
- Trees for sure. Their already plotting the overthrow of humans.
- Q: Can solar panels be installed on flat roofs?
- Yes, solar panels can be installed on flat roofs. In fact, flat roofs are often well-suited for solar panel installations due to their large surface area and easy accessibility. Mounting systems can be used to position the panels at an optimal angle for maximum sunlight exposure.
- Q: Can solar panels be used for powering a data center?
- Yes, solar panels can be used to power a data center. Solar panels generate electricity by converting sunlight into energy, which can be used to power various devices and systems, including data centers. By installing a sufficient number of solar panels and utilizing energy storage systems, a data center can operate on renewable solar power, reducing its reliance on traditional energy sources and minimizing its carbon footprint.
