Q: I thinking of buying a few solar panels, can anyone who had bought solar panels or sells them give me a price for them. I dot wanna over spend on them...
Solar okorder or another site to compare prices.
Q: Can solar panels be used in combination with wind turbines?
Yes, solar panels can be used in combination with wind turbines. This combination of renewable energy sources allows for a more reliable and consistent power generation, as wind and sunlight are complementary in nature. By integrating solar panels and wind turbines, the system can generate electricity during both day and night, as well as in varying weather conditions, maximizing energy output and increasing overall efficiency.
Q: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???

Q: Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port, can i just tie the wires together and run into the controller?? Will damage anything...Thanks guys
Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo
Q: Also, what's the solar panel's rate of producing electricity?
I'm okorder /
Q: i need to make a solar panel model for a project in science and i would like to know how to build a easy model at home that wont cost alot
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
Q: Do solar panels require a battery for energy storage?
No, solar panels do not necessarily require a battery for energy storage. While batteries can be used to store excess energy generated by solar panels for later use, it is not a mandatory component. Solar panels can also directly feed the generated electricity into the grid or be used to power devices in real-time, without the need for a battery.
Q: a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
As a matter of fact these types of facilities are being built today. People are already hard at work on it. Yes solar is more expensive that conventional electricity sources, but only at first. A solar power plant has no fuel costs and so although it costs a lot more to build at first over its life time it can actually cost a lot less. That doesn't even count the costs of byproducts from conventional power plants. Most people are not aware that particulate pollution kills between 00,000 and 200,000 people in the United States every year. The majority source of particulate pollution is electrical power production, but our electrical bill does not include the costs of those deaths. If the electric utilities had to pay their fair share of those medical costs electricity produced by fossil fuels would look a lot less attractive. Some people think solar panels take more energy to build than they every collect from the sun but that is not true. A solar panel generates the energy it takes to make it in between and 2 years and after that the power it generates is basically free. Solar panels are expected to last between 30 and 50 years, so that is a lot of free power. By the way, I installed solar panels on my house. They cost me about 6000 dollars (after rebates and tax deductions) and saves me about 000 dollars every year from my electrical bill. I have a 5 bedroom house and a family of three and our electrical bill averages just $35/month. That is in California with some of the highest electrical rates in the country. So I can say that solar works. There are dozens of companies working very hard to make solar power more affordable and they are being successful. The solar industry is about 7X larger in 2006 than it was in 2000. It is one of the fastest growing industries and has sustained growth of 40% per year for the last five years. Solar power will become the largest industry on Earth, but it will take some time. It is a very encouraging development.
Q: How much would it cost to make an average size house be able to depend on solar panels for all of its power?How many solar panels would you need and wear would you put them? Would the roof be large enough to support the panels needed?Do solar panels work well in higher latitudes like northern USA or southern Canada? Can you power your house for the whole year if you live in these environments? What kind of maintenance do solar panels require?
there are maximum of variables that would make your equipment greater or much less of a good investment. I even have had a equipment for a pair years and that i'm very happy with them. I distinctly propose you get a no legal duty quote, any respected photograph voltaic installation business enterprise would be prepared to try this. I actually have a 2 tale homestead with a pool (pump is one in all my great potential purchasers) in sunny CA and characteristic great orientation, and no coloration on the section. I have been given a three.seventy 4 kw equipment (20 panels i think of) that fee $26K, I gained a $0K rebate from my application and a $2K fed tax credit (at the instant the tax credit on the comparable equipment is $7800) i became into projected to break inspite of my utilization in 7.2 years, it would desire to be faster in view that my city has raised expenses via 20% interior the previous 2 years. The equipment produces approximately ninety% of my summer season utilization and approximately 50% of my wintry climate utilization.
Q: okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?
