Q: How do solar panels impact air pollution?: Solar panels have a positive impact on air pollution as they produce clean, renewable energy without emitting any harmful pollutants or greenhouse gases. By reducing the reliance on fossil fuels for electricity generation, solar panels help to decrease air pollution, improve air quality, and mitigate the harmful effects of climate change.

Q: I had an idea for new parabolic solar panels shaped like horseshoes. They can install them outside buildings facing the equator. They could angle them from the ground based on how many degrees latitude the location and rotate them according to seasonal changes. The disadvantage of photovoltaic panels is that they are not all capable of receiving direct sunlight. That is the quintessential reason I believe horseshoe solar panels are more effective than flat rectangular ones. One side could function in the morning; the middle could perform at midday; and the other could operate during the evening. That method seems more sensible than hourly positioning. I'm certain horseshoe panels could save and produce more electricity. A football stadium, shopping mall, or outlet center would be a fantastic place. What do you think?: Well here would be the problem with a horseshoe panel... Due to its shape, you will get a seriously uneven distribution of solar charge. Since the horseshoe shape resembles a parabolic function, the majority of the electrical photovoltaic cells will be spanned over the larger rise/run, meaning the two ends of the parabolic shoe. A way to combat this is that as it approaches 0 from both sides (0 tangency) is to put a higher concentration of photovoltaic cells in comparison to the two ends on either side. An even better design I would say would not to use a flat panel or even a horseshoe, but instead, use a sphere shape. It's globe-like shape would never need to be adjusted. The side pointing towards the sun would absorb and the remaining 360 degrees of shape would absorb ambient light which can trickle in tons of ambient charge. It is an eyesore but the round shape would be the most efficient. If you think about it, nature is the best example to model. Just look at a tree. It's general tree shape is rounded so that all the leaves can pick up some sort of light throughout the day.

Q: im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.: The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.

Q: what kind of rays are used in solar panels?: Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.

Q: How much space is required for installing solar panels?: The amount of space required for installing solar panels varies depending on the size and type of the panels. On average, a residential solar panel system typically requires around 100-400 square feet of roof space per kilowatt of installed capacity.

Q: I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?: One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .

Q: Can solar panels be used in areas with high levels of saltwater exposure?: Yes, solar panels can be used in areas with high levels of saltwater exposure. However, regular maintenance and cleaning may be required to remove salt deposits and prevent corrosion. Additionally, using materials with high corrosion resistance, such as marine-grade stainless steel, can help prolong the lifespan of the solar panels in such environments.

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, the efficiency of the panels may be affected due to the accumulation of dust on the surface, which reduces the amount of sunlight reaching the cells. Regular cleaning and maintenance are necessary to ensure optimal performance in dusty environments.

Q: I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?: . You want series, not parallel. (Add the voltages. Coonect '+' of the first to '-' of the next, and take your feed from the extreme ends.) 2. if you parallel them and you get less voltage than one alone, you got your polarity crossed up and are reading the difference between them.
