 315w Solar Panel Silicon Polycrystalline



 315w Solar Panel Silicon Polycrystalline



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.


To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

All PV models must be grounded by electrical connection of the module frames to ground. Please be careful in arranging the system ground so that the removal of one module from the circuit will not interrupt the grounding of any other modules.

 The  modules should be grounded to the same electrical point as described below.

Each PV module has a hole on the side frame of either a bolt, nut and washer grounding the module to the frame, a ground lug fastened by bolt or screw, or appropriate screw(hardware not provided).An example of acceptable ground connection using a bolt, nut and washer retaining a ground lug is shown in figure 3,in a connection of this type, the hardware(such as a toothed locked washer/star washer) must score the frame surface to make positive electrical contact with the frame. The ground wire must be considered within the requirement of local and regulation at the site of installation.

Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:How to connect a solar panel to an outlet?

Q:Solar Energy Panel VS. Energy Efficient Bulbs?
get a voltage tester and test the output from the panel if it is a 24 volt output which is then inverted the reading should be that of the inverter. however if you solar panel installer installed an LCD panel that controls the electricity you can monitor any faults from the panel. Make sure that the panel you feel is not working is producing the same amount of electricity as the others. As for the bulb buy a new one from a different make and see what happens but by testing the output voltage and power you are bound to find the fault.. I have just thought of this the panels supply electricity to big batteries that then distributes power to all the house perhaps the battery supplying power to your room is faulty or the connections to the inverter might be faulty. BEST option if you can afford it because it will be expensive is to buy a solar monitoring system that control the panel and batteries you can even connect it to your laptop and control all the power.
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:Will my 8watt solar panel charge a car battery and how fast?
8w will be .5 amps or so.That would charge a .5 amp battery in an hour.scale that up to whatever your battery amp-age is and you will have an idea.But given that car power is upwards of 40 amp/hour,your looking at 60 hours+ for a full charge on small battery.I run a 400w inverter for emergency lights and tv (get the occasional power cuts)from an old truck battery with big amps and charge it with an optimate,but in doing so I found that I had to run a amp check on power draw to find the lowest use lights.and tv,Some of the so called low power consumption compact fluorecents had widely variable draws,after testing one was found that drew .68 amp and I chose the lowest mesured tv amperage draw.not exactly an answer to your qu,but end use is the same.Running the lamp only I eventually gave up checking on the drain after about 30 hours and now just periodicaly charge the battery.Rounding off.tv draw maybe 3 amps for a small set and watched for say 6 hours would be 8 amps drawn.that would need -2 hours on your proposed set up in ideal conditions.I have kept the figures rough because there is always losses in any system .so it comes down to how much tv you watch and how much the sun shines

Q:How much energy does this particular solar panel produce?
Some great answers 23 max watts is per hour I live in an area that has 5.5 average sun hours per the solar insolation data which would give me a base of 676 watts produced per day for one panel. That 23 watts is most likely STC or standard test conditions which is far from standard it is ideal 70 degrees Farenheit with a 000 set flash PTC or physical test conditions are not always on labels and are not always accurate because of varied conditions. Heat has a huge factor on PV production. The panels should be derated by for the following reason ampacity correction or line loss Temperature correction PTC correction Inverter loss these corrections account for about 5 % on standard panels Our 676 watts per day has been dropped to 574 watts per day per panel Lets start with the light bulb. a standard 60 watt bulb uses 60 watts per hour. With the one panel we have chosen it would produce 5 hours and 45 minutes of illumination If we switch to a 5w CFL we get 38 and one half hours of illumination quite a difference yes Central Air will use about 2000 to 2500 watts per hour.This rule is not hard and fast as units will vary as well as conditions Lets use 2000 per hour times 8 hours of use is 6,000 watts we need 28 panels just for the ac. Probably another 28 for the rest of the house Of course these panel must be true south at 5 degrees mounted With a years worth of electric bills and a site visit I could come allot closer but lets say you need 60 of these panels this system would provide 973kHw per month at my location of 5.5 sun hours per day This would be a grid tied system as most state rebates require a grid tied system to qualify for rebates

Q:solar panels and calculations?
The okorder.com The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
