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.

 

COMPONENTS

 Polycrystalline Silicon Solar Panels 250w

 

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:how much do solar panels cost?
The okorder.com
Q:Solar Energy - What would these solar panels power?
A solar panel that is rated at 60 watts would produce that amount under the most favorable conditions of direct sunlight at noon in a good location. This would taper off to nothing at the beginning and ends of the daylight. A 60 watt Panel operating at full output for hour would produce 60 watt hours. If we assumed a straight line of output from zero to 60 watts and back to 0 again over 6 hours the average output would be 30 watts x 6 hours = 80 watt hours / day x 365 days = 65700 watt hours in a year / 2 = 5475 watt hours in a month. You lose about 0% converting from DC to AC. This reduces this to about 4927.5 watt hours. Your bill is measured in KW hr which are 000 times bigger. This is 4.9275 KW hr or .24% of your last month's bill. At a national average of about $.2 per KW hr the energy out put for one month would be equal to about 60 cents.
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
Q:The effect of colored light on a solar panel?
I okorder.com/
Q:Do solar panels shine/have luster? Please help me. Easy ten points!?
The problem with solar panels is that they often come with textured glass. This makes that the reflected light is scattered +/-0°. Therefore the 0.5° sun-disk small as it aprears in the sky will be blown up 40 times to a 20° reflection disk on solar panels. Find more information on zehndorfer.at/en/glaringsurvey Only a glaring survey can tell you exactly when and where you have to expect a dazzling effect.
Q:How many Solar Panels for my Pool?

Q:Where are the best places to put solar panels?
The best place is where they get the most sunshine. Naturally they will be exposed to rain and snow.
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:Solar Panels for home use?
Solar is a system, not just panels. Here is a link to the pro's that do this daily. You need to do the inside of your home, before you do the outside. Only then will solar work for you.
Q:Best and Affordable Solar panel for home?
Solar power systems are expensive and it takes time to recover the initial investment. The cheap solar panels that you are talking must be solar heat collectors which are most common in Asia. They are the most efficient type of solar power systems for the climate in South East Asia. They are mainly used to heat water. If you are looking for this, it will cost you about 25000-30000 for a 50-200 liter capacity. If you are looking for a solar power system only, then you can expect it to cost about 50000-60000 Rs approximately for 00 Watt/hr system. With this you can run most of the appliances and lights, fans etc. and your electricity bill will only be a fraction of what it is now. Hope this helps.
