- Q: I'm about to buy one but I don't really know which one is best for my home.
- One will give you enough DC voltage to light a 25 watt light bulb, [ one 45 watt panel is around $400. ] Now if your wanting AC voltage You have to buy a inverter, 5 or 6 deep cycle batteries, a switch Cables to transfer the voltage, a place out side to store the batteries, instalation brackets for the roof A Permit to Install them
- Q: Can solar panels be installed on a golf course or clubhouse?
- Yes, solar panels can be installed on a golf course or clubhouse. They can be mounted on rooftops, carports, or even on the ground in open areas of the golf course. Installing solar panels can help generate clean and renewable energy while reducing electricity costs for the facility.
- Q: What is the principle and structure of solar panels?
- Solar power generation system consists of solar cells, solar controllers, batteries (group) composition. If the output power is AC 220V or 110V, also need to configure the inverter. The role of each part is
- Q: Are solar panels affected by temperature?
- Yes, solar panels can be affected by temperature. High temperatures can cause a decrease in their efficiency and overall power output. However, some modern solar panels are designed to handle higher temperatures more effectively, minimizing the impact on their performance.
- Q: Can solar panels be installed on a car?
- Yes, solar panels can be installed on a car. Solar panels can be mounted on the roof or hood of a car to harness sunlight and convert it into electricity, which can then be used to power various systems or charge the car's battery. This can help reduce the reliance on traditional fuel sources and provide an eco-friendly alternative for powering vehicles. However, it's important to note that the amount of electricity generated by solar panels on a car may be limited due to the small surface area available for installation.
- Q: Okay, I think I understand what I'm doing, but I want to set up some solar panels on the roof of my garage, the building that gets the most sun, and I want to make sure all my math is correct in determining number of megawatts per year. However, my knowledge of electrical terms in quite n00bish, to say the least.Here is what I think I should be doing.The solar cells come at .75 Watts average power.I will install 4 panels of 64 cells each, with a total of 256 cells.
- For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
- Q: Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?
- 366 W/square meter on March 2 and tweaked based on lattitude eff = W out/Sun W in there are special heat meters to measure W in ======== IEC 62688 Certification; and UL cert in USA
- 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: im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?
- your solar panel has to be a bit higher in voltage than your battery to achieve charging. I.E . if your battery is 3.6 volts, your solar array voltage should be like 5.v. to make the charging take place. always a bit higher than your battery,. wattage is not so important, you can charge a whole slew of batteries with a .5 watt charger, it just takes a while. higher wattage will make it charge faster, tho. v. x a. =w.
- Q: How much Electricity does a standard Solar panel producein terms of Watts and in terms of Units( i.e. electricity meter attached in our House)If I have 20 Solar panels and an inverter , how much electricity will I Be able to harness and store (state that in terms of volts)Can I run Arefridgerator, Iron, Heaters, Plasma T.V. and other high Electricity Consuming Devices.
- Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
