Solar panel advantages

1.High quality guarantee using high conversion efficiency crystalline silicon solar cells.

2.High performance bypass diodes minimize the power drop caused by shade.

3.High transmittance, low iron tempered glass; high performance EVA, a weatherproof back sheet and sandblast electrophoresis aluminum frame extend the application of modules greatly.

4.Sealed. Waterproof. Multi-functional junction box gives high level of safety.

5.Durable Glass Surface. Our glass surface has been proven to withstand falling hard steel marbles that weigh over 1kg.It can also support over 350KGS of load per square meter

5.FAQ of Solar Module

1. Q: Do you have your own factory?

A: Yes, we have. Our factory located in Jiangyin city, jiangsu province.

2. Q: How can I visit your factory?
A: Before you take off from your country, please let us know. We will show you the way,or arrange time to pick you up if possible.
3. Q: Do you provide free sample?
A: Usually we do not offer free sample

4. Q: Could you print our company LOGO on the nameplate and package?

A: Yes, we can do that.

Q: Can solar panels be used in areas with high levels of rainfall?: Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.

Q: Can solar panels be used for agricultural purposes?: Yes, solar panels can be used for agricultural purposes. They can provide electricity for various agricultural operations such as irrigation systems, lighting, and powering machinery. Additionally, solar panels can be used to generate clean energy to reduce the carbon footprint of farming practices.

Q: I would like to know of any construction companies, road crews, or any company that uses solar panels in the Tampa area and throws them away. I like to recycle solar panels by repairing and processing what power I can from them. Know any companies that throw out used solar panels? If so, can you provide the name and number?: Test the battery. Connect the positive and negative terminals of the battery to the positive and negative probes of the voltmeter. If a voltage is read, the battery is still good. Remember, however, that this is a rechargeable battery, so if it is dead, it can be recharged.

Q: what do solar panels do?: The cost of electricity is increasing at a rate of 5 to 0 percent every year with no end in sight. A solar panel system captures the (free!) sun and turns it into usable electricity for your home.

Q: Can solar panels be installed on historical buildings?: Yes, solar panels can be installed on historical buildings. However, the installation process may require careful planning and consideration to ensure that the historical integrity and architectural significance of the building are not compromised.

Q: Where in the world are solar panels used. If it is used widespread across a continent just say which continent, other than that, just name the country. So where are solar panels used often?: Many okorder /... I have friends in Northern Michigan who use solar panels and wind generator for all their energy. They have been doing it for almost 20 years.

Q: How do solar panels affect the energy independence of a building?: Solar panels can greatly enhance the energy independence of a building by converting sunlight into electricity. By generating their own clean and renewable energy, buildings with solar panels can reduce or even eliminate their dependence on traditional energy sources like fossil fuels or the grid. This not only reduces the carbon footprint but also provides a sustainable and reliable source of power, ultimately granting greater energy independence to the building.

Q: Can solar panels be installed in areas with high levels of saltwater exposure?: Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed to withstand such conditions. These panels are typically made with corrosion-resistant materials and undergo rigorous testing to ensure durability in marine environments. Regular maintenance and cleaning may also be required to prevent salt buildup and optimize performance.

Q: Okay, me and my friends are going to fix up an old trailer that's out in the woods, we want something to be able to run small electric appliances off of, but it's to far to run power to. How can we make a good but cheap homemade solar panel that we could plug things into? The trailer is in more of a field so it gets plenty of sunlight! Thanks for any help! :): you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself

Q: I am currently building a house, iv designed it to be as self sustainable as possible, I'm in the process of installing solar panels but as I'm ordering online I was hoping someone here could tell me how many I would need to completely run a 5 bedroom home, just standard household appliances such as fridge and freezers, plasma tvs computers and of course lighting, various things like that, also I'll need power storage as well, some type of large rechargeable battery, any help would be great.: You're missing a few assumptions: - where on the globe? - how well is your house insulated, how do you plan to heat/cool your house? - why do you insist on power wasting appliances like plasma screens? Usually, unless it's absolutely impossible, a grid-tie-in system is much better than an insular system. You could use the grid to 'store' electricity for those times when the sun isn't shining and as fall-back if your yield isn't quite as good as you calculated. With the battery system, you'll have to specify your reliability requirements. If you want a 00% guarantee that you'll always have electricity, even if the sun is not shining for a week longer than you've planned according to the past weather history of your area, you'll either have to ridiculously oversize your battery (and panel) system, or plan for some sort of backup system anyway. Finally, if you're really planing such a system, you might want to take a look at the fridges and freezers used on sailboats: these use a eutectic cold accumulator, i.e. you 'charge' the fridge when the engine is running (or the sun is shining) and it'll then keep the temperature for another ~2...35 (professional systems) hours.
