Q: Can solar panels be installed on a house with a flat roof?
Yes, solar panels can be installed on a house with a flat roof.
Q: Can solar panels be installed on a billboard or signage?
Yes, solar panels can be installed on a billboard or signage.
Q: Can solar panels be installed in areas with high winds?
Yes, solar panels can be installed in areas with high winds. However, it is important to design and install the solar panel system with wind load considerations. Proper anchoring and structural support should be implemented to ensure the panels can withstand strong winds without causing any damage.
Q: I have:4- 5v 200ma solar panels5- 3v ,000ma solar panels- 7amp charge controller- 400watt inverterNow I have all my solar panels linked in series which in theory should give me 35v, 5.8 amps at 203 watts. Is this correct?The main question is, what kind of battery should I get so I can run my miscellaneous electronics off of it?I may not have explained it so well so if you need more information, feel free to ask.
I okorder and they have deep cycle batteries exclusively made for solar panels. but in theory you should get more than one because it only takes around 4-5 volts to charge the battery and you do not want to have it that high even with a charge controller which i would also recommend getting which is like $50 on OKorder but a charge controller is used so you do not overcharge the batteries and fry them or undercharge the batteries and weaken its life it gets it just perfect. it lets the current go in and when it is charged fully nothing goes in an nothing comes out.... for a inverter the one i was going to get was $70 500 watt inverter but changes it from dc to ac...hope i helped
Q: What are the supplies needed in a solar panel field, i know there are the panels. But what about batteries, and converters. Possibly other things, and how many will i need, for a certain amount of panels?
Short answer.. alot. A solar field is a big undertaking, and you'd be better off going with a solar consultant. I found this site and would recommend their services as they offer consulting, and are pretty big into solar (or atleast in my area..)
Q: What is the average size of a solar panel?
The average size of a solar panel is typically around 65 inches by 39 inches, or approximately 5.4 feet by 3.25 feet. However, the actual size can vary depending on the manufacturer and the specific model of the solar panel.
Q: Can solar panels be installed on data centers or IT facilities?
Yes, solar panels can be installed on data centers or IT facilities. In fact, many data centers and IT facilities are increasingly adopting solar energy as a sustainable and cost-effective power source. Solar panels can be installed on rooftops or in open areas surrounding the facility to generate clean electricity and reduce their reliance on traditional grid power.
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 frequent lightning storms?
Yes, solar panels can be used in areas with frequent lightning storms. While lightning poses a potential risk, modern solar panels are designed with safety features to mitigate the impact of lightning strikes. These features include grounding systems, surge protectors, and lightning arrestors. Additionally, solar panels are built to withstand extreme weather conditions, including lightning storms, ensuring their durability and functionality in such areas.
Q: Can solar panels be damaged by hail?
Yes, solar panels can be damaged by hail. Hailstones, especially larger ones, can cause cracks or dents in the glass surface of solar panels, which may impair their efficiency and performance. It is important to note that the severity of the damage will depend on the size and speed of the hailstones, as well as the quality and durability of the solar panel materials.
