In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q:How do solar panels reduce carbon emissions?: Solar panels reduce carbon emissions by harnessing the power of the sun to generate electricity. Unlike traditional energy sources such as coal or natural gas, solar energy does not produce any greenhouse gases when converted into electricity. By utilizing solar panels to generate power, we can reduce our reliance on fossil fuels and significantly decrease carbon emissions, contributing to the fight against climate change.

Q:Can solar panels be used for powering agricultural equipment?: Yes, solar panels can be used for powering agricultural equipment. Solar energy can be converted into electricity, which can then be used to power various agricultural machinery and equipment such as pumps, irrigation systems, electric fences, and even small tractors. This helps reduce reliance on traditional fossil fuels, promotes sustainable farming practices, and can save farmers money in the long run.

Q:What is the impact of dust and dirt on solar panels' efficiency?: Dust and dirt can significantly impact the efficiency of solar panels. When a layer of dust accumulates on the surface of the panels, it reduces the amount of sunlight reaching the solar cells, thereby reducing their ability to convert sunlight into electricity. This decrease in efficiency can range from a few percentage points to even as much as 20% in extreme cases. Therefore, regular cleaning and maintenance of solar panels are essential to maintain their optimal performance and maximize energy production.

Q:A local air conditioning company is advertising combining their (newly installed) central air conditioning system for homes, with roof solar panels. They say that the combination MAY reduce your electric bill. Nothing I can see to back-up their claims. Hmmmmm. And they offer, if you can get it; central air conditioning that runs on natural gas. Again, possibly cheaper than using electricity.Has any one actually tested to find out if solar panels and/or natural gas DOES, or DOES NOT save you any money to make it worth the bother?: Don't do it! It takes years to get your money back. Your better to put the money into insulation and or buying geo thermal unit. I knew someone who install solar panels on his roof to generate hydro and he didn't notice much of a change on his hydro bill and then he had roof problems . Central air units in last 2 years have become very efficient . Almost half the hydro of ones 0 years ago. If you can afford buy a geo thermal unit. It uses the heat of the ground in the winter 2 heat your house during the winter and the coolness of the ground to cool your house. They aren't cheap though. If you plan on living in your house for more than 0 years and have the room in the yard to install then go for it. No how you slice it though AC units use way more hydro than solar panels can produce. You would need about half a football field with a huge battery storage system to run a AC unit. When a company states you might on hydro I would stay away. Also remember they do not tell you about the costs of the upkeep on the solar panels and converter and batteries

Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?: That portion of the sun's light to which it responds, of which it converts 20% to electricity.

Q:Can solar panels be installed on a shopping mall or retail complex?: Yes, solar panels can be installed on a shopping mall or retail complex. Many shopping malls and retail complexes have large roof spaces that can accommodate solar panels. Installing solar panels on these buildings can help to reduce energy costs, decrease carbon footprint, and demonstrate a commitment to sustainability. Additionally, the solar panels can provide a source of clean and renewable energy to power the operations of the shopping mall or retail complex.

Q:How do you know when it is a good deal to buy a solar panel. For example, what is a good cost per watt, how many volts should I expect, etc.: first okorder / example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.

Q:How much space do solar panels require?: The space required for solar panels can vary depending on factors such as the size and efficiency of the panels. On average, a typical residential solar panel system can require around 100-400 square feet of roof space per kilowatt of installed capacity. However, advancements in technology have led to the development of more efficient panels that can generate more electricity in less space.

Q:Can solar panels be installed on government buildings?: Yes, solar panels can be installed on government buildings. In fact, many governments around the world are actively promoting the adoption of renewable energy sources, including solar power, in their buildings to reduce carbon emissions and promote sustainability. Installing solar panels on government buildings not only helps in reducing energy costs but also sets an example for the public and encourages wider adoption of renewable energy.

Q:Can solar panels be used in areas with high levels of electromagnetic interference?: Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, it is important to ensure proper installation and grounding of the solar panels to minimize any potential impact on their performance. Additionally, the use of appropriate shielding and surge protection devices can help mitigate the effects of electromagnetic interference on solar panel systems.
