FAQ:

（1）Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

（2）When did your company set up? You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

Q:My washer is 20 volts 60 gz,9.6 amps. The solar panels I am looking at are: Sharp ND-208U Solar Panels (208 Watt) List Price $,479.99 Only $,049.99 Sharp Solar Panels (208 Watt) List Price $,352.99 Only $,040.99 If I buy that will it be enough to run my washer?: The solar panels have a 2 volt DC output.You would have to get an inverter and a small battery bank to run the washer.

Q:how much energy does a kilowatt solar panel produce in a year? (average): You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.

Q:am having a 75 watts siemens solar panel and is giving me 2.89volts during bright light, i wanted to know can this be used to charge 00Am/hr battery?: Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.

Q:How much space is required to install solar panels?: The amount of space required to install solar panels varies depending on several factors, including the size and capacity of the panels, the energy needs of the property, and the available sunlight. On average, a typical residential solar panel system requires about 100-400 square feet of roof space per kilowatt of installed capacity. However, ground-mounted systems can also be installed if there is enough space available on the property. It is recommended to consult with a solar installer to assess the specific space requirements for a particular installation.

Q:If a solar panel (using 36 3x6 solar cells) puts out 60 watts, how many panels would I need (for a house) if I use a max of 2300 kWh in a month? I checked my electric usage for the past 2 years and the kWh is usually lower but I wanted to use the most kWh used (2300) for my question. Thanks!: One key piece of information missing is the average number of peak sun hours per day. This will vary by location. It is latitude, regional weather, and site shading must be considered. Another consideration is the loses. The 60 watt solar panel is a DC voltage. The 2300 kWh is for the AC power consumed. There are loses in the inverter to change the electricity from DC to AC. There are also loses for wire resistance, soiling of the panels, wire resistance, etc. To work out an example of the math, I'll use 5 peak sun hours and a total efficiency of 80%. The math can be worked out as a single formula but I'll break it into steps for you. (2300 kwh/month)(month/30.4 days) = 75.65 kWh/day (60 W)(5 psh)(80%) = 240 Wh/day = 0.24 kWh/day/panel # of panels needed = Energy use / Energy generated (75.65 kWh/day) / (0.24 kWh/day/panel) = 36 panels.

Q:How do solar panels affect the property's curb appeal?: Solar panels can enhance a property's curb appeal by making it appear more modern, eco-friendly, and energy-efficient.

Q:Can solar panels be installed on a car or electric vehicle?: Yes, solar panels can be installed on a car or electric vehicle. These panels can be mounted on the roof or other suitable areas of the vehicle to capture sunlight and convert it into electricity, which can then be used to power various components or charge the vehicle's battery. However, the amount of energy generated by these panels may be limited, and they are typically used as a supplementary source rather than a sole power provider for the vehicle.

Q:Are there any restrictions or regulations regarding solar panel installations?: Yes, there are restrictions and regulations regarding solar panel installations. These can vary depending on the location and jurisdiction. Some common restrictions include obtaining permits, adhering to building codes and zoning regulations, and complying with utility interconnection requirements. It is important to check with local authorities and consult with professionals to ensure compliance with all applicable restrictions and regulations before installing solar panels.

Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?: If you are in the desert and near the equator you will need fewer panels than if you live in a rain forest or Alaska. If you live in a wind tunnel with consistent strong wind, you will have better results than if you live where there often is a lull in the wind and changes of direction of the wind. If you already pump your water by hand, generate your own electricity by cycling using your legs, and go to bed whenever it gets dark out, you might make it. But if you tend to cook and launder on the grid, run a refrigerator, perhaps heat your house or air condition it, own various gadgets you plug into outlets to use, like lamps, puters, toaster, shaver, blender, dishwasher etc, you may not be able to get off the grid.

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 .
