INTRODUCTION

This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing CUSTOMER PV modules. This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.

CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.

CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.

 

GENERAL INFORMATION

The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All CUSTOMER modules are equipped with a permanently attached junction terminal box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require assembly.

 

COMPONENTS

 250w Polycrystalline Silicon Solar Panels

 

SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

TILT ANGLE

The title angle of the PV module is the measured between the PV module and a horizontal ground surface. The PV module generates the maximum output power when it faces the sun directly.

For the standalone systems with a battery where the PV modules are attached to a permanent structure , the tile angle of the PV modules should be determined to optimize the performance when the sunlight is the scarcest. In general, if the electric power generation is adequate when the sunlight is the scarcest, then the angle chosen should be adequate during the rest of the year. For grid-connected installations where the PV modules are attached to a permanent structure, it is recommended to tilt the PV module at the angle equal to the latitude of the installation site so that the power generation from the PV module will be optimum throughout the year.

Q:Can we cover up solar panels on our house with regular siding?
Strange question....most people now days are wanting to get solar panels and you are wanting to COVER them up. Are they not working? Have then removed before you put any siding in that area.
Q:Advice on Solar Panel....................................?
Unfortunately solar panels aren't very cheap, and to power as much as you would like, you'll need quite a few. Aside from that, they aren't the most dependable, and maintenance is pretty expensive. If there is a relatively continuous breeze in your area, you may want to look into residential wind turbines. They will provide electricity 24/7, and the small ones don't require very much maintenance. You won't need as many turbines as you would solar panels either because they provide a pretty decent amount of power. Hope this helps!!
Q:Building my own solar panels?

Q:What factors effect the amount of electricity produced from solar panels?
irradiance in watts/meter^2 (000-800w/m^2 depending on air quality) COS of angle to the suns rays efficiency of the panels (usually about 5%) age of the panels(one dead cell can drop an entire panel from the array) how dirty are the panels (dust, bird poop, leaves, shading) efficiency of the inverter (usually about 90%) All of these factors affect the amount of electricity produced. One other consideration is that in areas of extreme hot and cold the band gap of the silicon is changed.
Q:Solar panels in the Bay Area?
PV Solar panels all work the same. There aren't any climate specific ones. There is enough sun in San Francisco to produce energy using solar panels however, the the same panels located in a sunnier area will produce more energy. Depending on the size of your system, you will probably need a few more panels than an area that receives more sun to produce the same amount of energy. But they will still produce energy, even on overcast days. The solar installers will make all the calculations to determine what size system you will need to produce as much energy as you want. In California, you don't want to produce more than you consume in a 2 month period because currently, you are not able to sell your excess credits back to PGE after your 2 month cycle. Your system will cost more to produce the same amount of power than my system because I have less overcast days than you do. You will have to make the decision if the cost is worth your while. I expect my system to be totally paid for in around 8-9 years, working in the cost of inflation for electricity. After that, I will be paying nothing for electricty for as long as I stay in my house.
Q:Solar Panel System at Harbor Freight?
Solar Panel through charge controller to battery, battery to inverter, inverter to devices. a 75 watt panel would be enough to trickle charge a battery that is NOT being used to keep it at full charge. The average home requires 4000 watts MINIMUM. This would require MANY, LARGER panels, charge controller, a battery stack, and at least LARGER inverter (preferably 2, 2000 watt inverters, unless you want to REALLY get expensive!)
Q:Im looking at getting solar panels.
Most major cities have construction signs and other public things powered by solar panels. We have parking meter stands, USGS meters, street lights, etc. when these lose efficiency, they need to be replaced. They still work at about 60 percent efficiency. Learn who services these items and ask how to get them at a reduced rate or even for free. Be personable and nice and go to the source physically, not via e-mail. You can get a solar panel to run just about anything
Q:solar panels in space?
You do realize that the sun is 50 million km away don't you?
Q:how to store energy from solar panels?
If you are buying a kit, chances are there is an instruction manual in there on how to mount your solar panels. You can also ask for assistance from the store.
Q:Is it worth getting solar panels fitted on my roof?
In 2007, the cost of solar photoelectric power was 38 cents US per kwh while the cost of coal power was 0.6 cents per kwh but consumer costs for power were 2 cents per kwh as additional coal power plants are not being built so wind and natural gas are being built. Without government incentives, solar power are not economic. However, the UK has extensive subsidies for solar, I would suggest that you learn how to perform Internal Rate of Return ( IRR ) calculations and Net Present Value ( NPV ) calculations to evaluate your financial decision, excel has an excellent =XIRR() function to do this with. Most people talk about payback periods but that's due to the poor level of financial education in the population and payback periods don't give you an appropriate evaluation of the time value of money. With solar power, it's a razor thin line of economics so you have to get the calculations right to know what's in your best interest, the laymen hearsay isn't going to do it.
