- Q: Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- I don't know what you have avilable to you down there, but if you were in the states i'd say go to a camping supply store they have lots of solar options out today. check one link below
- Q: Can solar panels be installed on hospitals or healthcare facilities?
- Yes, solar panels can definitely be installed on hospitals or healthcare facilities. In fact, many hospitals and healthcare facilities around the world have already embraced solar energy as a sustainable and cost-effective solution. Solar panels provide a reliable source of clean energy, helping these facilities reduce their carbon footprint and dependence on traditional energy sources. Additionally, solar power can contribute to long-term cost savings, allowing hospitals to allocate more resources towards patient care and medical services.
- Q: my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP
- If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
- Q: I have tried researching on the internet and just cant find any real answer. I know that the amount of electricity produced when taking in the suns rays depends on the placement of the solar panels but I am just looking for ball park figures. Thanks
- Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.
- Q: For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.
- if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
- Q: What is the typical warranty period for solar panels?
- The typical warranty period for solar panels is around 25 years.
- Q: How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
- The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.
- 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 to power a museum?
- Yes, solar panels can certainly be used to power a museum. Solar panels are a reliable and sustainable source of energy that can generate electricity to meet the power requirements of a museum. By harnessing solar energy, museums can reduce their carbon footprint, lower energy costs, and promote environmental sustainability.
- Q: Can solar panels be installed in extreme temperatures?
- Yes, solar panels can be installed in extreme temperatures. However, extreme heat or cold can affect their efficiency and performance. It is important to consider the temperature range and potential impacts on the solar panels when planning and installing them in extreme climate conditions.
