Q: I want to know how you can store energy using a solar panel. The energy stored needs to be stored so that a light or laptop charger can plug in to it.: Batteries my man... but you will need a charge controller the silicon panel will produce dc and you will need an inverter for an ac light

Q: Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?: No. The solar panels would never be balanced. Those blades need to be very balanced. Additionally, how would the solar panels get the power from a rotating blade to the ground? It is better to have separate units. What we ought to be concerned with is having large solar panel farms. These are counter-productive to going green, as they still require long and harmful power transmission lines. Solar panels ought to be put on top of buildings which would be using that power. Any additional power not used could be added to the power grid. For those types of clean energy that are not practical on the roof might get space near the building, keeping the transmission lines as short as possible. Large farms ought to be owned by the nation, keeping the cost of the power to the customer as low as possible. Power companies rip off consumers with their price gouging. It is time to let the burden of making a few rich at the expense of the many end.

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.: I don't know where you got the idea you have 8 hours of sunlight. Assuming clear skys and no dust, forest fires, clouds or other impediments, the average sunlight available in North America averages out to approx. kw/sq. meter. That's the maximum available, at midday. Multiply this be the efficiency of the cells (I assume about 0%) and it means about 00 Watts/sq m. Since you have said you have a tracking system, this works out to about 00 * .344 * 2 = 43W/h per day (per sq. meter).

Q: Are solar panels worth the investment?: Yes, solar panels are worth the investment. They offer long-term financial savings by reducing electricity bills and the potential for selling excess energy back to the grid. Additionally, they contribute to a cleaner and more sustainable future by reducing carbon emissions and dependency on fossil fuels.

Q: How do solar panels affect the property's energy resilience?: Solar panels can significantly enhance a property's energy resilience by providing a reliable and sustainable source of electricity. They reduce dependence on the grid, allowing homeowners to generate their own power and potentially store excess energy in batteries. In the event of a power outage or grid failure, solar panels can continue to supply electricity, ensuring uninterrupted energy supply and boosting the property's overall energy resilience.

Q: So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?: You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.

Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?: No, the top argument is that extra CO2 is inflicting the ambience to keep greater warmth from the sunlight. Having image voltaic panels might scale returned the quantity of CO2 interior the ambience we are putting in it real now via giving us an means source that doesn't emit CO2, and that's approximately it.

Q: Can solar panels be used in areas with high levels of noise from transportation?: Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not directly affect the functionality of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the installation of solar panels is done properly to avoid any physical damage caused by vibrations or other factors associated with transportation noise.

Q: I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!: Solar water heating panels are often heavy, depending on their design. Solar electric panels are rarely heavy - at mabye 3 lbs. per square foot, including mounting racks, they are not much heavier than typical roofing materials. Whether the panels pay for themselves is a highly individualized answer, dependent on your state and local rebates (if any), how much sun your area gets, and the cost of your electricity. Just about any Californian can break even, but it can take 5-20 years. Prices are dropping, so this should get better next year (but federal tax credits expire - could be renewed, a Democratic president would be unlikely to veto). A house that is conservative in electrical usage (this usually means no air conditioners in the summer or electric heat in the winter) generally has enough roof area to supply 00% of its electrical needs. We have 0% of our roof dedicated to panels, and it supplies essentially 00% for us. The best way to get answers to your questions is to ask a few solar companies to do a free analysis and quote on your house. You can always say no. If you're thinking of doing it yourself, that's possible, but not trivial. It's also possible that a professional could install it for less than you could if you bought the parts yourself and installed it yourself. We installed our own, but the experience is a little dated - from 2006. There's a video at the bottom of the page below, if you want to see what we did.

Q: Ok so my electric bill is through the roof because of the air conditioner (mini-split). Is there any kinds solar panel I can buy at a store and install it myself? Do I need any skills? Which brand? blah...blah...blah...: You can attempt to install your own solar panels...just do the homework first! I suggest looking at ways to decrease your overall energy consumption first even if installing solar panels. Doing this will save on the amount of panels you need. Have included a reference that may be of use to you.
