Q: How do solar panels perform in extreme temperatures?: Solar panels can still generate electricity in extreme temperatures, but their efficiency may be slightly affected. In high temperatures, solar panels may experience a decrease in their power output due to increased resistance in the electrical circuits. In extremely cold temperatures, solar panels may become less efficient temporarily, but they can still produce electricity as long as there is sunlight. Overall, while extreme temperatures can have a minor impact on solar panel performance, they are designed to withstand a wide range of weather conditions and continue to produce clean energy.

Q: What is the average lifespan of a solar panel?: The average lifespan of a solar panel is typically around 25 to 30 years.

Q: Can solar panels be installed on desalination plants?: Yes, solar panels can be installed on desalination plants.

Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be: Solar power is expensive power. The costs have been coming down but unless it's the only option or there are government subsidies, it would still be less expensive to buy electricity from the grid. The way you compare the upfront costs of solar power with monthly bills is by the Internal Rate of Return equation or the Net Present Value calculation. Vendors will use the payback periods to try and convince you into a financial decision where they reap all the benefits so you need to learn how to do a proper financial analysis. The average US household uses about 950 kwh per month, unless you are very wealthy, you will not be able to afford enough panels for that and you probably don't have enough roof space. You will have to reduce your power usage as much as possible. Batteries are expensive and inefficient. Lead acid batteries are 95% efficient at discharging but only 50% efficient at charging. A battery based system would not only include the costs of the batteries but would also double the number of panels required. Lead acid batteries have their lives rated at only 20% draws on their capacities, they lose a lot of life with each deep cycle. There are deep cycle batteries which have thicker plates but they are also rated at 20% draw and a deep cycle battery's life would drop to 94% with just one deep cycle draw. This means, it's customary to buy five times your diurnal capacity worth of batteries, fortunately this allows for several cloudy days. If you do want to have deep discharges, buy Nickel Iron batteries. You will want a grid tied system instead where you sell the power you produced to the utility and buy back what you need effectively turning the grid into a 00% efficient battery. Of course, there are costs involved as the utilities would likely charge a monthly fee just to be hooked up so this cost must be taken into account. There is also the risk that the utilities may change their net-metering arrangements on you later.

Q: Solar panel for battary charging: Are okorder / or hook up several meters and supervise the process regularly. The UPS has no role in the charging—only the discharging.

Q: Can solar panels be installed on any type of roof?: Solar panels can be installed on almost any type of roof, including asphalt shingle, metal, tile, and flat roofs. However, the feasibility and ease of installation may vary depending on the roof's condition, angle, and orientation towards the sun.

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: I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks: I think the point you're trying to make is that solar electricity is more expensive than other means of mass produced electricity today, and I would agree. However, that doesn't mean that solar panels are not worthwhile, especially to a consumer in the right location. After the electric company adds in its distribution fees and profit, residential solar electric can actually be cheaper. And in fact, we have had panels on our roof for the past 5 years. Somewhere in the world, there's a factory producing AA batteries to use in flashlights, cameras, and so forth. I'm certain the factory does not run off AA batteries, yet I find AA batteries invaluable for certain things around the house.

Q: Can solar panels reduce electricity bills?: Yes, solar panels can reduce electricity bills. By harnessing solar energy to generate electricity, homeowners can offset a portion or even all of their electricity consumption from the grid, leading to lower electricity bills.

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.
