High Efficiency Monocrystalline Solar Module with Organic Printed Solar Cells

Product Description:

1, Product  desciption

Inverter circuits designed to produce a variable output voltage range are often used within motor speed controllers.

The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load.

Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools. (See related: variable-frequency drive ) Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table.

The generated gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.

2, Features of  the  product

Inverters convert low frequency main AC power to higher frequency for use in induction heating.

To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC Sources employed, the structure becomes more reliable and the output voltage has higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved.

This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors. There are three kinds of level shifted modulation techniques, namely:

 · Built-in 1 year data logger for system analysis

· Charge and discharge status display

· Acoustic load disconnect pre-warning

· Load status indication

· Choose between 5 load disconnect algorithms

· Boost/absorption/float PWM-regulation (series type)

· Integrated temperature compensation

· Covered terminals (up to 16 mm2 wire size)

· Full solid-state protection

The first thing to figure out is the length of road in need of street lights.

This can be a small entrance road only a couple hundred of feet long to miles of streets through an area. Does the area currently have any type of lighting available.

 What is the reason for needing street lights in this area

Is the electrical grid already nearby or would you need to call in the power company to bring in electrical lines.

 If the electric needs to be brought to the area, how much is this going to cost? Depending on how far the grid electric is from the location of the needed lighting, this can be quite expensive.

How much lighting is needed on the street? Do the lights need to be dark sky compliant.

Do the street lights need to run from dusk to dawn or for only a specified number of hours at night.

Are the street lights able to dim in the middle of the night and still provide enough lighting.

These questions need to be answered before you can decide on how many lights you will need to complete the project.

Benefits of solar cell cost

•     Solar power makes up three-quarters of new U.S. electricity generation, and more than half a million U.S. homes and businesses have now gone solar.**

•     You can lock in surprisingly low electricity rates by going solar with Sunrun. And we lock in those rates for 20 years. Then the next time utility rates rise, you’ll be laughing all the way to the bank.

•     Your neighbors are already saving. Did you know that Americans are installing new solar panels every 3 minutes? They know that solar electricity is clean, renewable and easy on the wallet.

•     Sunrun takes care of everything. We design, install, and maintain your system the entire time. We also guarantee your energy production. You get a worry-free system – while enjoying 20% savings on your electric bill.*

•     It’s a nice thing to do for the environment. You can help create a planet run by beautifully clean energy from the sun.

How much money can a solar cell cost save

The real question is "Is it worth switching to solar generated power?" The answer depends greatly on your situation, economically, geographically, and politically. It's still a significant up-front investment, whether that comes out of your own pocket or you find a bank that may, possibly, with much convincing, lend it to you. The payback period - more accurately, the break-even point - or how long will it take to recuperate the cost of ownership, varies extremely. In sunny climates where electricity prices are rising, switching to solar basically locks in your electricity price and the system can pay for itself in a few years. But if you're still connected, i.e. a grid-tied system, your utility company may charge you more for using less, unless they have buy-back agreement, which most in my area do not. Also with grid-tied, if the grid goes out, you can't use your array anyway, unless you have a means of completely isolating it from utility power.

So, is it worth switching? Although the price of the components have dropped over the years, this is still a very complicated question.

In many places now, you can go solar for $0 or close to $0 down through solar leasing companies or through simple bank loans. Then you’re just paying monthly payments like you would on a house, car, or college loan. However, in this case, your payments are likely to be less than the amount of money you’re saving on your electricity bill. So, really, you’re not paying any more than you’re already paying for electricity you’re saving money!
