45W CNBM Polycrystalline Silicon Panel for Home Using
Production description
Most solar modules are currently produced from crystalline silicon (c-Si) solar cells made of multicrystalline andmonocrystalline silicon. In 2013, crystalline silicon accounted for more than 90 percent of worldwide PV production, while the rest of the overall market is made up of thin-film technologies using cadmium telluride, CIGS and amorphous silicon[7]Emerging, third generation solar technologies use advanced thin-film cells. They produce a relatively high-efficiency conversion for the low cost compared to other solar technologies. Also, high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft, as they offer the highest ratio of generated power per kilogram lifted into space. MJ-cells are compound semiconductors and made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging PV technology using MJ-cells is concentrator photovoltaics (CPV).

- Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- It will generate MUCH more current if placed outside of the window. The best position is pointing directly south. Over the period of one day, you will get the most average sunlight pointing in that direction.
- Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?
- your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there
- Q: Are solar panels weatherproof?
- Yes, solar panels are designed to be weatherproof and can withstand various weather conditions such as rain, snow, hail, and wind. They are made with durable materials and have protective coatings to ensure long-term performance even in harsh climates.
- Q: Are solar panels suitable for all climates?
- Solar panels are suitable for a wide range of climates, but their efficiency may vary depending on the amount of sunlight available. While they can still generate electricity in cloudy or colder regions, they perform best in areas with high solar insolation and minimal shading. Advances in technology have made solar panels more adaptable, allowing them to be utilized effectively in various climates around the world.
- Q: how to make a solar panel without buying any kit?Any things at home that can be used for solar panels(what are they?)procedures how to make a solar panel
- There are 2 kinds of solar cell/panel. Electrical and thermal. Passive thermal is the easiest. It can be made with clear glass bottles or jars. The bottles or jars must first be cleaned and sterilized to prevent the growth of algae or bacteria. Fill these about 90% full with water that has tsp of chlorine bleach per gallon. Put the caps or lids on tight. Seal with hot melt or other waterproof glue like RTV silicone. Arrange these in an array. You can use cement or just build a wood frame. Even simpler is just to put the bottles on a board or window sill. Place this in a sunny spot. The water will be heated by the solar radiation and will stay warm several hours after the sun is no longer shining on them. A an active thermal cell is different. For this you need a medium to heat. Silicon oil is often used but your could just use water. You need a collector, reservoir, heat sink, and circulating pump. These must be arranged in a manner so that the medium (water) is pumped to the collector where it is heated. It passes through the heat sink to transfer the heat and then returns to the reservoir. To make an electrical panel you can buy components. Photovoltaic cells and the components to mount them, wire them and then change the current generated into a type and voltage you can use.
- Q: Can solar panels be installed on agricultural or farming operations?
- Yes, solar panels can be installed on agricultural or farming operations. In fact, many farmers and agricultural businesses are increasingly adopting solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be mounted on rooftops, open land, or even on barns and sheds, providing clean and renewable energy to offset electricity costs and reduce carbon emissions. Additionally, solar panels can help farmers take advantage of unused or underutilized land, providing dual benefits of energy generation and agricultural productivity.
- Q: What is the average size of a solar panel?
- The average size of a solar panel is typically around 65 inches by 39 inches, or about 5.4 feet by 3.25 feet. However, the size can vary depending on the manufacturer and the specific model of the solar panel.
- Q: How do solar panels impact the local job market?
- Solar panels have a positive impact on the local job market by creating new employment opportunities. The installation, maintenance, and manufacturing of solar panels require a skilled workforce, leading to job growth in these sectors. Additionally, the renewable energy industry stimulates economic development and attracts investments, resulting in job creation across various industries.
- Q: Why should I have a Generator if I have Solar Panels.....?
- Well the sun don't shine at night does it. Nor much on cloudy days. You either need a generator or a whole lot of batteries. The batteries are a pain to maintain, they're expensive to install and they have to be replaced periodically. Generator's probably a decent alternative. I'm sure most people just stay on the grid for their backup. Even better if you live in an area where you're allowed to sell back excess capacity. If you're looking to spend this kind of money anyway you could look at a household fuel cell that runs on natural gas. Awesome technology, though if you buy the unit all prebuilt and ready to go it's going to run you like 50,000 bucks.
- Q: I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
