- Q:i used 734 killowatts of power last month, any idea on how many solar panels i would need. What im looking for is to somehow hook up my central air to solar panels.
- LOL!! There is a lot more to this than you might imagine. This is a very rough approximation but look at the attached and column labeled 6.3KW. Look down that column and you see where it says Est. First Year KWH Generated ,025. So if we were to assume that each month it will produce ,025/2 kwh. (not true for January but I am trying to keep this simple. The installed price without any rebates is $44,050. ;-) Sorry! You will find some a little cheaper... some a little more expensive but none are a LOT cheaper than this. (this price does not even include energy storage, so the sun goes down and you will stop producing electricity). This is why, when people start looking at this sort of thing, they always do what they can to conserve electricity first. It is always much cheaper to conserve, then worry about alternate energy.
- Q:For my Product Design Coursework I am designing an environment friendly building according to a clients' specifications. I need to find out the dimensions of 0000 watt solar panels. any help would be much appreciated!
- Crudely, for crystalline silicon panels today, 0 watts per square foot is a good budgetary number. The actual panel will be smaller, but you will need space for mounting, and there are always obstructions you need to keep away from.
- Q:Are solar panels safe?
- Yes, solar panels are safe. They are designed and installed to meet strict safety standards. They do not produce any emissions, and the risks associated with solar panels are extremely low. However, it is important to ensure proper installation and maintenance to maximize safety.
- Q:Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks
- It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.
- Q:I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.
- You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.
- Q:I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
- 4 awg wire is good for 5 amps and will handle 9 total panels at 2 volts
- Q:was looking at a few different sites, here is one of them
- There okorder
- Q:How do solar panels affect the overall comfort of a building?
- Solar panels can positively impact the overall comfort of a building by reducing energy costs and improving indoor temperature control. They generate clean and renewable electricity, which can power various systems such as heating, ventilation, and air conditioning (HVAC) units. This helps to regulate the indoor temperature more efficiently, leading to a more comfortable environment for occupants. Moreover, solar panels can also reduce reliance on the grid, ensuring a more reliable energy supply and enhancing the comfort and stability of the building.
- Q:How do solar panels impact the electricity bill?
- Solar panels can significantly reduce or even eliminate electricity bills by generating clean and renewable energy from the sun. By harnessing solar power, homeowners can offset their electricity usage with the electricity produced by the panels, resulting in lower overall energy costs.
- Q:Plz also label the price for the panel. I want a small panel but can produce a sufficent amount of energy. thank you :)
