Q: Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?: Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Q: if I have a battery bank of of 6 L-6 Trojan batteries, 6V 390AH, wired in series parallel to give me 2V at 70AH (or 4,040WH) what kind of solar panels should I purchase assuming I have 8 hours of sunlight, a solar tracking system and I want to make sure I can fully recharge my batteries everyday if i use up all the power every night?i understand there are efficiency issues to consider which i have not calculated in yet. thanks.: If okorder /... yet, it's worth browsing the off-grid section. 8 peak equivalent sun hours a day on average is very achievable with tracking, but are you sure you really want to spend on tracking? It's a lot of trouble and expense - might be cheaper just to get more panels. Also be aware that when you have a lead-acid battery bank capable of (say) 000 Ah, that is the capacity that the batteries could supply as a one-shot deal. If you ever took that much from them, they would be ruined. Typically, you would try to take only 20% of the capacity before recharging, although some batteries let you take 50%, with reduced life. Have you considered wiring the batteries as 36 volts? There would be more efficiency, and less problems with equalizing the batteries when charging. Unless 2 volts is really the output that you need most. Sorry to redirect you, but I can't recommend that forum too highly. Lots of considerations.

Q: We are thinking about useing solar panels for our house.Does anyone know about solar panels? If so could you please tell me some information on them,and the cost for a home,to install them.: Solar electricity systems can save you more money.

Q: Can any body tell me how much Electricity can 0 Standard solar panels produce in a day( in terms of Watts)Or else please tell me how many Watts is 5 volts of electricity?: You are missing one bit of information in order to get an answer. Watts = Volts x Amps Find out how many amps the collector can put out and you can then plug in the numbers into the equation and get your answers.

Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.: materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them

Q: The ancients used skylights for light in lieu of electricity. Light was used for drying, even cooking foods and drying clothes. Solar clocks/sun dials were once popular but now we have battery operated clocks. Where have we tapped into any of these resources since the outdated solar clothes drier nicknamed the 'clothes line'?: For simple starters, look to the gigantic strides technology has made due to the science of the laser. Its light power at its most extreme.

Q: Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you: A solar panel is a panel of a certain material that is very sensitive to light. Now, when you place if out in the sunlight, the photons enter that material, and gets converted to energy in the form of electrostatic electrons. These electrons gets carried away by the small silver wires you see running zig-zag over the panel, and is then used as electronic current. It is actually a lot more intricate and detailed than this, but this is more or less how it works. The reason is works better in sunlight, is simply because sunlight has a lot more energy behind it than lightbulbs and other sources, but they work as well!

Q: Can solar panels be used in areas with high wind speeds?: Yes, solar panels can be used in areas with high wind speeds. However, it is important to consider the structural integrity of the mounting system to ensure that the panels can withstand strong winds. Additionally, proper installation and maintenance are crucial to ensure the longevity and efficiency of the solar panels in such conditions.

Q: I know the basics of how solar panels work. Solar panels convert sunlight into DC electricity which is stored in batteries which would need to be run through an inverter to convert it to household AC. But is there a way for the appliances to use the solar panels electricity FIRST and any additional power from the grid? Is that how it works or do they only run specific devices(water heater, pool pump, etc)?: The batteries are inefficient and expensive. Lead acid batteries are 95% efficient at discharging but only 50% efficient at charging so you need double your power consumption in solar panels for a battery based system. The big breakthrough was in grid tied inverters, these can be connected to the grid and synchronizes it's frequency to the grid thereby selling the solar power to the grid. The house electric system remains on the grid so you buy back the power when you need it effectively turning the grid into a 00% efficient battery by accounting. This saves you the cost of the batteries and the inefficiencies of the batteries halving the number of panels that you need. Grid tied solar can be a third the price of a comparable battery based system. The utilities will usually still have a service fee and may have limitations such as you can only sell the amount of power that you use and the sale can only be credits versus future energy purchases. There will also be the inefficiencies of the grid tied inverter but it would be at full load which is when it is the most efficient often 95% whereas the partial load use of a battery based system operates the inverter at an average of 65% efficiency which is why DC appliances are highly recommended for a battery based system.

Q: I would like to know how much a solar panel would cost for a wingspan of 208 ft for a plane: 2,000 that we have used 4 project , its based on the cell size
