Product Description

- Mono-crystalline solar cell demonstrates higher photovoltaic conversion efficiencies, no performance degradation and appearance deterioration occur.
- SIN as anti-reflection coating, shows extremely uniform dark blue color. The color may change subject to customers' specifications
- Advanced gettering and passivation, as well as aluminum BSF ensure high performance for solar cells.
- High purity metal pastes result in cell contracts of low series resistance and low degradation.
- The bus-bars of the cell (AG and AG/A1 pastes) are easy to solder. The grid pattern is easy to align for automatic soldering. The cell remains good flatness and thus is easy to cut. The internal stress in the cells is small and thus cell breakage rate is extremely small.
- Different Power output available, rang from 5Watt to 180Watt.
- Comes with junction box and by-pass diode, can charge 6V and 12V batteryies for all type.
- Can be used as Power Stations, battery Charger for vehiclee, boat, electric fence and so on.

Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.: If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.

Q: What is the payback period for solar panels?: The payback period for solar panels can vary depending on factors such as the initial cost of installation, location, energy usage, and available incentives. However, on average, solar panels tend to have a payback period of about 5 to 10 years.

Q: Can solar panels be used to heat water?: Yes, solar panels can be used to heat water. Solar water heaters use the energy from the sun to heat water, typically through the use of solar thermal collectors. These collectors absorb solar radiation and transfer the heat to a liquid, which is then circulated to heat the water. This renewable and environmentally friendly method can be used for residential and commercial purposes to provide hot water.

Q: What are the maintenance requirements for solar panels?: The maintenance requirements for solar panels include occasional cleaning to remove dirt and debris, checking for any damage or loose connections, and ensuring that the panels are receiving sufficient sunlight. Additionally, regular monitoring of the system's performance and scheduling professional inspections can help identify and address any potential issues.

Q: Can solar panels be used in areas with high levels of vandalism?: Solar panels can be used in areas with high levels of vandalism, but additional precautions may need to be taken to protect them from potential damage.

Q: what do solar panels do?: The cost of electricity is increasing at a rate of 5 to 0 percent every year with no end in sight. A solar panel system captures the (free!) sun and turns it into usable electricity for your home.

Q: Can solar panels be installed on a small scale?: Yes, solar panels can be installed on a small scale. In fact, many residential homes and small businesses have successfully installed solar panels to generate their own electricity and reduce their reliance on the grid. Additionally, small scale solar installations are more affordable and easier to manage compared to large-scale projects, making them an accessible option for individuals and communities looking to adopt renewable energy.

Q: I want to build a standalone wifi repeater -- powered by the sun. The problem is how much solar power and how big of a battery?net draw 4.5v @ 0.66A with loadnet draw 4.5v @ 0.60A no loadI'm assuming the best choice would be a 6v battery with a a couple diodes in series to induce ~.5v drop. Then, I need something to charge it -- I found 2v 6w solar chargers in the automotive section of Sears and 6v 2w solar chargers in the marine section of Dick's Sporting Goods.How many solar panels and what capacity batteries should I use? Is this the best method or should I use a voltage regulator and go with 2v batteries?I need this to be as cheap and simple as possible...: You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)

Q: Can solar panels be damaged by hail?: Yes, solar panels can be damaged by hail. Hailstones can cause physical damage to the panels, such as cracks or shattered glass, impairing their ability to generate electricity efficiently.

Q: Can solar panels be installed on schools or educational institutions?: Yes, solar panels can be installed on schools or educational institutions. In fact, many schools have already adopted solar energy as a sustainable and cost-effective solution. Installing solar panels on educational institutions not only reduces their carbon footprint but also provides valuable educational opportunities for students to learn about renewable energy.
