Product Description:

1. Structure of Polycrystalline Silicon Solar Modules 72Cell-305W Description

Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

-Tests by independent laboratories prove that  modules:

 Fully conform with certification and regulatory standards.

 Withstand wind loads of up to 2.4kPa and snow loads of up to 5.4kPa, confirming mechanical stability.

 Successfully endure ammonia and salt-mist exposure at the highest severity level, ensuring their performance in adverse conditions.

- High effi ciency, multicrystalline silicon solar cells with high transmission and textured glass deliver a module effi ciency of up to 16.0%, minimizing installation costs and maximizing the kWh output of your system per unit area.

- Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing module mismatch losses leading to improved system yield.

- Top ranking in the “TÜV Rheinland Energy Yield Test” and the “PHOTON Test” demonstrates high performance and annual energy production.

 5.  FAQ of Polycrystalline Silicon Solar Modules 72Cell-305W

(1) Can you offer the test report of the module?
     Sure. All the solar modules must pass necessary tests including EL test and ultra-red test and other visual test of the apperance, and the test report presents all the detailed data of the modules.
(2) How  to confirm about the quantity and the type of solar module?
     It depends on the solar system where  you want to put into use the solar modules. We have experienced engineers to design for your order and you need to give more information to fix the details.
(3) How long will you deliver the solar modules?
     We need to purchase the materials according to the list confirmed by you and put into production, and  we will do our best to get your satisfaction.

Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:Power Point on solar panels?
Refuse to do the work on the grounds that it is not good for your school to switch. If the teacher tries to give you an F, escalate the problem to the principle and then the local news agency. Teachers are not allowed to force brainwashing.
Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?
why okorder.com and we will tell you and everyone else what they would need.we will tell you to the dollar what it takes to accomplish your desire.thanks tommy
Q:where I can find this solar panel?
heres a list of solar companies. perhaps u could browse them
Q:simple definition of how a solar panel works?
Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.
Q:Why are solar panels still so expensive?
materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them
Q:Solar panel angle question..?
You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
Q:Solar Panel Charging?
You're right. The solar panels must produce a voltage equal to or slightly greater than that of the batteries. So you need to either switch to a 2 volt battery or add two more solar panels of the same current rating.
Q:Can I install solar panel straight to battery on my truck?

Q:SOLAR Panels?
$8,000 invested at 5% interest would pay you $900 per year for the rest of your life. If you spend $40 per month and would save 25% of that, you would save $420 per year. To be fair, the savings would creep up with the electric rates but this would be off-set by maintenance cost and equipment attrition.
