FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

 

Q:So idk how to connect a solar panel to a battery ...is it like a series connection from the solar panel to the battery, or a parallel connection from solar cell to battery? (to charge) please and thank you
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
Q:I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?
There okorder /... ). These systems provide relatively high efficiency, since they don't convert sunlight to electricity, and they can be used to supplement or replace energy used for space and hot water heating - some of the largest residential uses of energy. Like any other appliance or household system, solar panels used to collect heat will require periodic maintenance. Hope this helps.
Q:im interested in starting a solar panel manufacturing company. ive researched on how to make them and it doesnt look too hard, and is definitely something i can figure out. i would be starting from nothing so my question is what are the chances of me actually selling a lot of panels and the business actually succeding?thanks
At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
Q:Are solar Panels worth it, Do they really quot;save moneyon electricity?
“Where you have good (sunlight) and access to financing and a combination of federal and state incentives, you have a number of markets around the country that are very vibrant, and it’s very cost-effective with financial paybacks in the order of five and 0 years,” said Robert Margolis, a senior energy analyst at National Renewable Energy Laboratory (NREL).
Q:What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
I know that the US uses 500 Gigawatts (giga is 0 ^9). I think a solar panel meter square might generate at most 00W. So you would need 500E9/00 = 5 trillion of these. 5 trillion square meters is 70 kilometers on a side. Dont forget about night and clouds!
Q:planning to get one, for a store/house, we use alot of electricity at least 500-3000 dollars a month. how much money would this save us? how big would we have to get the solar panel?[aproximately]
Hi, One or two new windmills may not cost you as much I believe. Just my suggestion anyway.
Q:I don't know anything about where to buy solar panels. I just want to save on the electric bills.
Solar panels could supply an air conditioning unit but it would be SUPER expensive to do. Air conditioners are power hogs.
Q:Can solar panels be installed on theme parks or entertainment venues?
Yes, solar panels can be installed on theme parks or entertainment venues. In fact, many theme parks and entertainment venues around the world have already embraced solar energy as a sustainable and cost-effective solution. By installing solar panels, these venues can generate their own clean energy, reduce their carbon footprint, and save on energy costs in the long run.
Q:I have created a solar setup in my shed i have 2x.5w solar panels i am hoping to charge my 55ah car battery how long would it take to charge the battery and how many watts could i used a day
To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.
Q:Can solar panels be installed on hospitals or healthcare facilities?
Yes, solar panels can be installed on hospitals or healthcare facilities. In fact, many healthcare facilities are increasingly adopting solar energy as a sustainable and cost-effective solution. Solar panels can help hospitals reduce their dependence on traditional energy sources, lower operating costs, and contribute to a greener environment.
