SOLAR PANELS GOOD QUALITY AND LOW PRICE-3W

Q: Can solar panels be used in combination with other renewable energy sources?: Yes, solar panels can be effectively used in combination with other renewable energy sources such as wind turbines, hydroelectric power, or geothermal energy. This combination, known as hybrid renewable energy systems, allows for increased reliability, better utilization of resources, and a more stable power supply.

Q: Can solar panels be installed on refugee camps?: Yes, solar panels can be installed on refugee camps. In fact, solar energy is often a viable and sustainable solution for providing electricity in these camps. Solar panels can be easily installed on rooftops or in open spaces, helping to meet the energy needs of refugees and improve their living conditions. Solar power can provide lighting, power for charging electronic devices, and even help run water pumps or refrigeration units. Its renewable nature and independence from the grid make it an ideal energy source for refugee camps, where access to reliable electricity is often limited.

Q: Can solar panels be installed in areas with high levels of air pollution?: Yes, solar panels can be installed in areas with high levels of air pollution. While air pollution can potentially have a slight impact on the efficiency of solar panels, it is not a significant barrier to their installation and operation. Solar panels primarily rely on sunlight, which is still present even in polluted areas. Additionally, solar panels can even contribute to reducing air pollution by providing clean energy alternatives.

Q: I mean when light hits the solar panel where does the energy go and what does it become? Be specific.: Visible light from the sun is in the form of photon before hitting the solar panel. In a silicon solar panel, the photon is caught by the semiconductor material. Energy equivalent of the photon is then used to excite an electron from the semiconductor molecule. The aggregate of free flowing electrons form the current in a closed electric circuit. The efficency of conversion from sun light to electricity is not 00%. The majority of light energy hitting the solar panel is dissipated in the form of heat. As technology advances, the conversion efficiency is improving, hence reducing the cost of solar energy.

Q: Is there a small solar panel system that I can put in my bedroom window and charge my phone and run an alarm clock off of? Or one I can run a microwave off of?: Yeah they have them to charge phones but to use a microwave you would have to use one to charge a 2 volt battery with them from there an inverter . You could probably get a system like that for around $50 or so off OKorder . Don't get me wrong solar panels do cost allot but for what you want it for just to run a microwave isn't going to cost you all that much . Just go to OKorder and look for solar phone charger and get an idea of what you want . Thumb up for Sam above me . People just think everything is expensive because they put no effort in there shopping .

Q: Can solar panels be installed on a boat or RV?: Yes, solar panels can be installed on both boats and RVs. They provide a sustainable and efficient source of energy, allowing for off-grid power generation while traveling or moored. The panels can be mounted on the roof or other suitable areas to capture sunlight and convert it into electricity to power various onboard appliances and systems.

Q: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.: Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.

Q: Are solar panels worth it?? I mean the price you by for them up front is a lot, so you properly need a loan for it. So how does it work? Won't the loan be just as much as you electric bill?Im just really confused about it.: If your purchasing solar panels for a building or colony where a few families live together, the cost of the panels can be distributed or shared. And loan and electricity bill wont be the same. Loan is a one time transaction while electricity bill you have to pay monthly and everytime. You dont have to buy solar panels every month lol. So its a better option to spend on solar panels although it maybe a big amount, rather than paying high bills every month....

Q: The inverter I am using gets the required 2 DC volts from the solar panel, but fo some reason it just won't output the 0 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 2 DC rating. Help me out please...: Solar panels output a very small amount of current. Even though you're getting 2V from the panels, you aren't getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter. Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 2V source must be able to deliver 20W of power regardless of voltage. In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator. Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel's output rating, then it can power it directly, provided you have 00% light input into the panel.

Q: I live in the UK, I have no savings (so would have to take out a loan of about ?8000), I don't know how long I plan to stay in my house, I might want to move in a year or two to take advantage of a better job so I want to keep the option open of being able to sell my house without having to pay off the cost of having the panels fitted (which I probably won't get back on the increased value they add to my house).What are the main advantages of having solar panels?What are the pitfalls the ever so eager cold callers with quotas to fill don't tell you about?Basically is it worth having them?Thankyou.: In 2007, the cost of solar photoelectric power was 38 cents US per kwh while the cost of coal power was 0.6 cents per kwh but consumer costs for power were 2 cents per kwh as additional coal power plants are not being built so wind and natural gas are being built. Without government incentives, solar power are not economic. However, the UK has extensive subsidies for solar, I would suggest that you learn how to perform Internal Rate of Return ( IRR ) calculations and Net Present Value ( NPV ) calculations to evaluate your financial decision, excel has an excellent =XIRR() function to do this with. Most people talk about payback periods but that's due to the poor level of financial education in the population and payback periods don't give you an appropriate evaluation of the time value of money. With solar power, it's a razor thin line of economics so you have to get the calculations right to know what's in your best interest, the laymen hearsay isn't going to do it.
