6. FAQ of Polycrystalline Silicon Solar Panel Type CR290P-CR250P
(1) Can you offer the test report of the module?
Sure. All the solar modules must pass necessary tests including EL test and ultra-red test and other visual test of the apperance, and the test report presents all the detailed data of the modules.
(2) How to confirm about the quantity and the type of solar module?
It depends on the solar system where you want to put into use the solar modules. We have experienced engineers to design for your order and you need to give more information to fix the details.
- Q:what percentage of sunlight is converted into electrical energy in a solar panel?
- Depending on the type of solar panel, any where from 6% to 42.8%.
- Q:I am told there are night vision goggles to see at night due to invisible light still hitting earth. I am also told that there are other beams, x-rays etc hitting earth.Why couldn't they invent a solar panel with dual power in the day?It could harness both visible and invisible light, and at night be single?Anyone know why they can't make an invisible light solar panel?Is this possible?What happens if future cars have night vision windshields instead of lights?
- Solar panels work when the metals from which they are made release electrons when hit by radiation. There is a threshold that, below a certain wavelength/frequency, they do not eject electrons. As frequency increases, more electricity flows. Radio and infrared are the least energetic electromagnetic waves.
- Q:Can solar panels be used in areas with high levels of air humidity or moisture?
- Yes, solar panels can be used in areas with high levels of air humidity or moisture. While excessive moisture can potentially reduce the efficiency of solar panels, modern solar panel designs are equipped to handle such conditions. They are built with protective coatings and materials that prevent moisture penetration and corrosion. Additionally, regular maintenance and cleaning can further ensure optimal performance in humid environments.
- Q:Can solar panels be installed on a sports stadium or arena?
- Yes, solar panels can be installed on a sports stadium or arena. Many stadiums and arenas around the world have already implemented solar panel systems to generate renewable energy and reduce their carbon footprint. The large roof space and open areas surrounding these venues make them ideal locations for solar panel installations. Additionally, the energy generated by these panels can be used to power the stadium's operations and even contribute to the local power grid.
- Q:I have a shed that has wiring run for light bulb and a couple outlets. It is in a dark corner of my yard and at night is kinda creepy to go in with even a flashlight. I am weighing the option/expense of running electricity from the house on an overhead line versus putting up a 45 watt solar panel on the metal roof with inverter, battery etc. Sunlight is good to excellent at the location. Question is - will this be sufficient for the occasional use of light and an outlet? What can I expect? Pros and cons appreciated
- For okorder /... Electric power. Rather than an overhead cable you can bury a cable or PVC conduit and power the shed with 20AC. You can easily supply 5 to 30A of 20V AC that supply all of your power needs without the issues and limitations of the Solar system. If your shed is within 200 ft of your home you should be able to power the shed for less than $400 if you do the work.
- Q:Can solar panels be used in areas with high levels of lightning activity?
- Yes, solar panels can be used in areas with high levels of lightning activity. However, they may be more susceptible to damage from lightning strikes compared to other structures. To mitigate this risk, proper grounding and surge protection measures should be implemented to safeguard the solar panels and associated equipment.
- Q:I am heading to Nepal and do not want to lose power on my cameras but they can only be charged via quot;plugging inquot;. A USB connection does not work. Looking for a solar panel to clip to my bag or carry that I can plug in the charger as if plugging in to wall outlet. Thanks.
- Solar panels require a charge converter before it can be used by an AC source. There is no direct solar panel with built in charge converters that I know of because, when purchasing panels, you must purchase the wattage requirements of the job (this can be several panels linked), and a charge converter that will handle the <? panels required. A chain of stores up here in Canada have a portable battery pack that has a solar panel to increase its charge capacity or duration, but its not something you would want to lug around for long periods of time, because is weights in about 3 lbs.
- Q:Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
- The $25,520 price amounts to about $8.5 a watt which is high, I would've expected between $2.50 to $5 a watt and those are dated prices so it sound like the vendor is raking the price up. You didn't mention how many months your $75 financing is for but keep in mind that at 3 kw for 8 hours a day for 30 days at 2 cents per kwh, you would generate $86.40 so you will be paying about twice as much for your solar power as you would had you bought the power from the grid. Mind you, for people on a fixed income, there is the security that the cost will not rise ( if properly insured ) so there could be an advantage to paying a premium for your power if you're on a fixed income. I'd say it's a rip off but I also believe solar has a ways to go even with subsidies before it's an economic choice and that's usually not a popular stance with the green washed crowds.
- Q:Can solar panels be used in cold climates?
- Yes, solar panels can be used in cold climates. While the efficiency of solar panels may slightly decrease in colder temperatures, they can still generate electricity even in freezing conditions. In fact, solar panels can even benefit from the reflection of sunlight off snow, which can increase their output. Additionally, advancements in technology and the use of anti-reflective coatings have improved the performance of solar panels in cold climates.
- 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.
