- Q: I heard the wind turbines, solar panels so far provide America with around 2% of our energy. So since liberals appear to want to replace natural energy with man made products, that cause massive pollution by the way to make- How long will that take 30 years, 00 years? How many Wind Turbines will Airplanes and birds and parachute jumpers smash into, isn't that a problem? How do we rid of natural energy before we have the LIBERAL BACK UP PLAN - WE DON'T REALLY HAVE ? How do they think this is gonna work? Its not logical, we need to come up with more ideas! That Battery idea kinda sucks since Batteries Need natural energy to work.
- Both the wind turbines ( windmills) and solar panels are less costly to implement than nuclear power and have less disaster potential. They have proven that Windmills miles out in the ocean are a great source of power. This dose not consume any land. For land bound areas they should use public roadways to line the windmills. For areas without sustainable winds they can use the combined effect of windmills and solar power. Honey, any motor needs oil. Whether it is a generator for a windmill or a nuclear reactor. Motors are what runs the world. Consider the amount of oil to run a nuclear facility. Tons more than a generator motor. Once a turbine is activated (motor started) the winds themselves turns the windmill. Each turbine is lined up with the next (wind farms) to push wind at the blades, they each push each other.
- Q: was looking at a few different sites, here is one of them
- There okorder
- Q: When you get solar panels do you connect them to the grid?
- Not directly and it also depend on where you live. If where you live has net metering then they would be indirectly connected to the grid, there is equipment involved besides just the panels on the roof.
- Q: How do solar panels affect the grid during times of high electricity demand?
- Solar panels can help alleviate the strain on the grid during times of high electricity demand by generating clean and renewable energy. By producing electricity directly from sunlight, solar panels can contribute to the overall power supply and decrease the reliance on traditional fossil fuel sources. This reduces the burden on the grid, mitigates the risk of blackouts, and helps meet the increased energy demand more sustainably.
- Q: All I know is they check for amps watts voltage and everything... they dont have to be used for solar panels but um they have like alittle spinny thing in the middle of them. you spin it around to what you wanna test such as the amps watts voltage and stuff.... idk what their called but im looking to buy one to test my solar panels when they come in
- Voltmeter.
- 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 ensure that the solar panel installation is designed and engineered to withstand the specific wind conditions in the area. This may involve using specialized mounting systems and ensuring proper anchoring and structural reinforcement to prevent damage or dislodgement due to strong winds.
- Q: I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
- good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
- Q: Can solar panels be used in areas with high levels of dust?
- Yes, solar panels can be used in areas with high levels of dust. However, it is important to note that the efficiency of solar panels may be affected by the accumulation of dust on their surface. Regular cleaning and maintenance can help mitigate any potential decrease in performance caused by dust build-up.
- Q: So idk how to connect a solar panel to a battery ...is it like a series connection from the solar panel to the battery, or a parallel connection from solar cell to battery? (to charge) please and thank you
- it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
- Q: if you know the area of the panel can u calculate for the wattage or voltage of the panel..
- One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
