- Q:How do solar panels affect the appearance of a home or building?
- Solar panels can have a significant impact on the appearance of a home or building. They are typically installed on the roof, and their sleek and modern design can often enhance the aesthetic appeal of a property. However, some people may find the presence of solar panels less visually appealing, especially if they are not installed in a well-integrated or discreet manner. Ultimately, the effect on appearance depends on personal preferences and the design choices made during installation.
- Q:If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.
- a million. Do they scratch actually? No How do I eliminate snow from them without scratching them? purely wipe the snow off 2. What does the maintenance of many image voltaic panels contain? sparkling them with faucet water and paper towels as quickly as a month. 3. Are all image voltaic panels created from the comparable fabric, regardless of length? extremely the comparable.
- Q:I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
- They're more efficient than nothing, or fusion for that matter since fusion hasn't gone anywhere in the last 30 years. Since most energy is used during the day time when its light out solar panels will do pretty well. In most habbital places on the planet its light out for a good part of the day while wind doesn't blow steadily in most places.
- 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:Can solar panels be installed on a building with historical significance?
- Yes, solar panels can be installed on a building with historical significance. Many historical buildings have successfully incorporated solar panels into their design without compromising their architectural integrity. This allows for the preservation of historical structures while also promoting sustainable energy practices.
- Q:How can solar panels be used for heating water?
- Solar panels can be used for heating water by using the energy from the sun to heat up a fluid, typically water or antifreeze, which then transfers the heat to a storage tank. This heated water can be used for various purposes such as showers, washing dishes, or heating indoor spaces.
- Q:Can solar panels be used for powering a concert venue or entertainment center?
- Yes, solar panels can be used to power a concert venue or entertainment center. Solar energy can be harnessed through panels and converted into electricity, which can then be used to power various aspects of the venue, such as lighting, sound systems, and equipment. By utilizing solar panels, these venues can reduce their carbon footprint and potentially save on energy costs in the long run.
- Q:How much does it cost to replace a solar panel?
- The cost of replacing a solar panel can vary depending on the size, quality, and type of panel, as well as any additional installation costs. On average, a basic solar panel replacement can range from $500 to $1,500 per panel, but it's recommended to consult a solar installer or supplier for a more accurate estimate tailored to your specific needs.
- Q:My house is aligned exactly North-South, so I have no roof facing South. Is it worth installing solar panels? Are there any good options for dealing with this situation?
- Several options: The panels could be mounted on the ground. We mount panels on a roof because they are out of the way but it is not the best choice. The highest output (and most expensive) choice is to mount the panels on the ground fixed in a heliostat (sun tracking mechanism) Far better if the panels are on the ground where they can be more easily cleaned to promote top efficiency. If you have the room they can be mounted in an angled array. Panels can be mounted on the side of a house or on the roof using racks to position the panels properly. We usually say that if we can get the panels within 5 degrees of due south it is sufficient. You could even mount the panels flat onto the side of a house and use mirror mounted heliostats to reflect sunlight to them. All of these options will be more expensive than a perfectly oriented home. There are also other alternatives for producing electricity, conserving electricity through energy savings, or production of other forms of energy that offsets electrical usage. A site survey is the best way to determine this.
- 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 .
