Q:Need help with Solar Panels (FAQ's and opinions)?
Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
Q:solar panel model HELP!!!!!!!?
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:Any companies that have solar panels?
Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.
Q:what is the best way to go solar?
solar water heater and solar power system.
Q:Solar Energy Panels, a good idea?
Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
Q:Cost of a solar panel?
The cost of solar panel depends on per Watt..typically per watt cost is around USD 4-5, so if you take 75W solar panel it will cost around USD 300-375. I hope this helps
Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:Can I use a 250 watt solar panel to power a medium sized upright fridge?
How many watts does your fridge consume? Do you want it to work at night when the solar panels aren't doing anything? Probably not.
Q:how do i pick out solar panels to match my battery bank?
Hi okorder.com/
Q:I need help with solar panels?
Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
