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: Didnt solar panels use to cost around $250,000 5 years ago?
- I okorder to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
- Q: My house uses 500 kw a month, air conditioning is the main consumer, is it possible to install solar panels in my roof to produce this amount, and aproximate cost, thanks .
- Replace your compression driven airconditioner with a gas fired absorption cycle air conditioner (there'll be a government subsidy or grant for that due to the R22 being phased out), install vacuum tube solar thermal collectors at a tenth the price of solar photovoltaics and use the hot water for the absorption cycle heat source with the natural gas burners as a backup. This avoids all the energy losses involved in the various energy conversions and solar thermal uses all wavelengths of solar energy while many photo-voltaics uses only one wavelength (newer dye based, multi layer, and quantum dot photovoltaics are all about using more than one wavelength of light). Solar thermal will also give you hot water and residential heating which are the other two big energy uses in a home. If you are bent on spending ten times the money on photovoltaics instead of solar thermal then figure out how many hours you actually run your AC for, use the filter replacement counter on your programmable thermostat to give you how long your fan is running in days and multiply that by 24 then divide your 500 kw/hrs by this value and since the power company only buys power from you at half the price that they will sell it to you at and you will have to buy power back at night, multiply by a fudge factor of say .5, this gives you a rough estimate of how many watts of solar panels you'll need to install in kilowatts, multiply this by 0,000 and that's roughly how much it will cost you in dollars (assuming $0 per watt installed, solar cells can be as low as $ per watt to manufacture but those aren't available yet and you also need to have them assembled into panels and installed so $0 per watt is a reasonable figure, people usually use values from $4 per watt through $9 per watt). Then after you get over the sticker shock, reconsider solar thermal.
- Q: i am wanting to build a small tiny house running 3-4 2 volt 5 watt light bulbs for a lighting source and using a Koolatron Fun Kool 26 Quart 2V Portable Mini Fridge This cooler consumes 4.5 amps at 2 volts. The conversion is: 4.5 amps (X) times 2 volts (=) equals 54 watts. and i want a solar system that will have back up for 2 days with the lights on for probly 5-6 hours a day so theirs no room for error
- you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
- Q: Can solar panels be used to heat water?
- Yes, solar panels can be used to heat water. Solar water heating systems use the sun's energy to heat water, typically through the use of solar thermal collectors. These collectors absorb sunlight and transfer the heat to water, which can then be used for various purposes such as bathing, washing, or even space heating.
- Q: im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?
- Completely self-efficient and autonomous??? Forget it. Too expensive. It's only worth if you use like 8 lights (2-20w) about 4 hours a day, a fridge, a tv about 4 hours/day and basically nothing else or a few low consume stuff. Forget about microwaves, dryers, or other stuff. Too much watts. And that would cost you no less than 5000-6000$. You need panels (about 4 or 6 20w would suit maybe), 2 batteries (about 600Ah at least), inverter(500w/24v) and a regulator, lets say a 30A one. Just stick to normal energy supply. A single 20w panel may cost about 750$ at least.
- Q: How do solar panels withstand hail or other weather conditions?
- Solar panels are designed to be durable and withstand various weather conditions, including hail. They are made with tempered glass that is highly resistant to impact, ensuring that hailstones won't damage the panels. Additionally, the panels undergo rigorous testing to ensure they can withstand extreme weather conditions, such as strong winds and heavy snow. The frame surrounding the panels also provides stability and protection.
- Q: Can solar panels be used for powering a museum or cultural institution?
- Yes, solar panels can certainly be used to power a museum or cultural institution. Solar panels are a sustainable and renewable energy source that can generate electricity by converting sunlight into usable power. By installing solar panels on the rooftops or surrounding areas of a museum or cultural institution, it is possible to produce clean energy that can be used to power the building's lighting, heating, cooling systems, and other electrical needs. This not only reduces the institution's carbon footprint but also helps save on energy costs in the long run. Additionally, solar panels can serve as a visible symbol of the institution's commitment to environmental sustainability, inspiring visitors and the community to embrace renewable energy solutions.
- Q: Around this time here in Georgia we will begin to get some big storms with high winds. I have a solar panel on a mount that isn't all that sturdy and could be knocked over with any winds pretty much above 5mph. I can't put anything in the ground to do this. I used to have it mounted to the roof of a playground for the most sunlight, but because of the angle of the sun and the tree leaves, I have to have it on a quot;portablemount so I can move it throughout the day, and I can tell you one thing is certain, and that's that it isn't the most sturdy thing ever. I'll have it a little better next weekend but it'll still be able to easily blow in the wind. Should I just hang the panel along the wall during a storm then reconnect it to its base once it's over?I'm pretty good with wood, so any wood creations to help out with the thing would greatly help. Just please keep it on a low budget.
- You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.
- Q: Can solar panels be installed on warehouses?
- Yes, solar panels can be installed on warehouses. In fact, warehouses are often ideal locations for solar panel installations due to their large roof spaces, which can accommodate a significant number of panels to generate clean and renewable energy. Additionally, warehouses tend to have uninterrupted sunlight exposure, making them well-suited for solar energy generation.
