FAQ

If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?

Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!

Yes, solar panels can be installed on historic homes or buildings. However, it is important to consider the specific regulations and guidelines set by local historic preservation boards or authorities. In many cases, there are alternative installation methods available that minimize any visual impact on the historic aesthetics of the building. It is advisable to consult with experts in historic preservation and solar installation to ensure compliance with any necessary requirements.

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.

probably a deep discharge lead calcium batteries, with a switching regulator cycloconverter or cycloinverter output to match the current and voltage requirements of the operated device.

Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?

500 Watt Solar Panel

I am trying to built a circuit that will power two USB ports (both 5V and 0.5 amps) from the output of a solar panel that produces 20V at 0.2 amps. I have a voltage regulator that runs at 5v and 0.5 amps but I can't figure out the best way to boost the current up to 0.5 amps before I incorporate the voltage regulators.

The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.

Yes, solar panels generally require permits for installation. The specific requirements and regulations for obtaining permits may vary depending on the location and local building codes. However, in most cases, permits are necessary to ensure compliance with safety standards, electrical codes, and zoning regulations. It is advisable to consult with local authorities or a professional solar installer to determine the exact permitting process in a specific area.

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.

I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).

portable panels are too small to be much use for a modern household. A panel appx 20 inches square might supply a laptop computer... but it won't keep your refrigerator running.
