12 volt solar panel hook up

Even if you're on a budget, it is still possible to fit a solar panel system to your caravan or Rv. It would appear as though you need a physics degree and a masters in automotive electronics to adequately fit a solar system to your rig. That is nonsense, of course, but the point is that a bit of common sense, patience and background reading on power requirements when free camping is all you need. The accessories that you run off the battery are not dealt with here — this is all about harnessing free power from the sun.

Complete Guide To Installing Solar Panels

Below is a list of 30 of the most common Solar related questions we receive from customers that could help answer some of the queries you may have. The Watt is the basic unit of power. It is named after the eighteenth-century Scottish inventor James Watt. The higher the voltage, the more electrical current will flow in the circuit. Amperes or Amps , is the measure of electric current. One Amp is equal to a number of electrons passing a point in a circuit each second at a certain voltage.

Amp hours is a measure of stored power. Amp hours is the number of Amps drawn, for the amount of time in hours that you draw that current. These wafers are created from silicon ingots. The ingots are either block-cast from multiple silicon crystals poly-crystalline or grown to form a single crystalline structure mono-crystalline. The ingots are cut into slices around to micrometers thick to form the wafers.

The ingots are generally made from p-type doped silicon, and n-type silicon is then applied as a surface layer to the wafer. This creates the n-p junction which allows the flow of electrons. Anti-reflective layers are then applied to the wafer before metallic connections are made in a grid-like pattern on the front side of the panel and a plate across the full area of the wafer on the back side.

These metallic connections are screen printed using a silver paste on the front and an aluminium paste on the back. The wafer is then fried at a few hundred degrees celsius to create contact between the silicon and the metal electrodes. The wafers are now ready to be connected to form the solar module. The number of watts or the amount of Power you need is determined by the requirements of your system with regards to both charging and to running particular loads.

The power rating or wattage of your panels determines the rate at which you can deliver charge to your system. You need to ensure that you have enough solar panels to cope with the amount of power you plan to use. A good rule is to overrate your system so that it can cope with cloudy days and unexpected power usage. The power rating of your inverter determines what appliances you can run from your inverter. If you want to run aW microwave from your inverter you would need at least an W inverter.

It is important to keep in mind that running an appliance such as this from an inverter will drain your battery bank considerably. As a general rule of thumb, if you divide the amount of watts an appliance uses by 10 for a 12V system or 20 for a 24V system, this will give you the current draw on that system. Amorphous type solar technology uses Silicon in a non-crystalline, random form. It can be deposited onto many different substrates to give effects like flexibility for use in different applications.

Crystalline silicon type solar technology refers to monocrystalline and polycrystalline panels. These panels are created from silicon in a tetrahedral lattice type structure. This structure gives crystalline silicon type solar modules a higher efficiency per square meter than amorphous type modules. The amount of solar panels you require will be determined by the amount of charge that you need to return to your system during the sunlight hours of each day.

If after reading the instructions you are still unsure of how to connect your devices please contact a qualified auto-electrician or REDARC electronics on 08 The wiring size for your system is determined by the overall length of cable involved in the system, and the amount of current drawn over that length of cable. The amount of current drawn by the system is related to the amount of current your solar panels can output for the cable between the solar panels and the battery, and is related to the amount of load you are planning to use for the cable between the battery and your loads.

Required cable thickness can be easily worked out using our cable size and voltage drop calculator. The type of battery you choose depends on the application for which you are using it. It is recommended that a deep cycle battery be used as an auxiliary battery because generally an auxiliary battery is discharged to a lower level and then recharged as opposed to a starter battery which is generally kept at a particular charge level.

It is important to ensure that your regulator is designed to charge the type of battery you plan to install in your setup. Most regulators will have specific charging profiles for the four different types of automotive batteries commonly used today. It is also important to consider where the battery is mounted. If you plan to have the battery inside a caravan for example, you must get a sealed battery because an unsealed battery will generate harmful gases during charging.

Your best bet is to contact a battery supplier and discuss your requirements with them. A 12V solar panel is designed to output at least enough voltage to charge a 12V battery under worst case conditions low light level, high temperature etc. A 12V battery needs at least This means that in perfect conditions a 12V solar panel may output around 17V or more.

If you plug a solar panel, which is generating 17V, straight into your battery it is easy to understand how this can cause damage. Solar regulators are designed to accept the voltage from the solar panel, and output a voltage that is safe and useable to charge a battery. A good regulator will incorporate a 3 stage charging output. Given that there are 24 hours in a day, an 80W panel can effectively run a load of around 1. You want to run the fridge 24 hours a day, and the camp light for 6 hours each night.

Given that there are 24 hours in a day, a W panel can effectively run a load of around 2. This depends on the size of your fridge, how long you plan to stay away from any other power sources and the size of your battery bank. Please refer to the Typical Usage Calculator for more accurate information. This depends on the size of your inverter, how long you plan to stay away from any other power sources and the size of your battery bank.

The typical setup for a camper trailer would involve a 80L fridge and a couple of LED lamps. The typical setup for a caravan would involve a fridge, inverter, television, lighting and possibly some other equipment. Typically a camper would require a 40 — 50L fridge and a couple of camp lights. So as a rough estimate it would take around 2 hours to recharge your battery.

Ideally your solar panel should be in direct sunlight for best performance. This means that as much as possible your solar panel should be perpendicular to the direction of the sun rays. Your panels will provide the most power at peak sunlight. This requires no cloud cover and occurs at the middle of the day. Your panels will continue to provide power at a reduced rate before and after this peak sunlight period at any time whilst the sun is out.

Your panels will obviously not provide any power before dawn or after dusk. REDARC solar panels are tested to handle rain and hail, and our portable panels can be tied or pegged down so as not to lose them in windy conditions. Having said that, generally when the weather is stormy, rainy or there is hail, sunlight levels are not high enough to generate power from your solar panels.

Therefore if possible it would be best to bring your panels out of the weather during these conditions. Solar panels do generate electricity in cloudy weather although their output is diminished. The use of a MPPT regulator will help get the most out of your panels during these conditions. You should clean your solar panels on a regular basis for best performance as anything that may be blocking sunlight from the photovoltaic material will reduce the efficiency of the panel.

Panels should be cleaned using a microfiber cloth as scratches may reduce the performance of your panels. If your panel has stopped working please run through the steps outlined in the troubleshooting guide. If after completing the troubleshooting guide you have not solved the problem, please contact REDARC on 08 for further assistance. When a solar panel is partially shaded the cells that are in the shade will not output any power.

A solar panel with bypass diodes will ensure that if a cell is in the shade and not providing any power, the other cells and therefore the panel as a whole will still provide an output. Panels without bypass diodes will lose all power when partially shaded. Each cell in an 80W solar array provides about 0. Therefore every 2 cells lost will mean a 1V drop in output.

An 80W panel will output around 16V — 18V, which means that if more than about 6 cells are shaded the panel is less likely to charge a 12V battery. REDARC rigid solar panels are designed to resist environmental conditions such as rain, hail and strong winds. My solar panel gets very hot when I leave it out in the sun, is this normal? Solar panels when left in the sun will get hot for two reasons.

Firstly, the sun beating down on the surface of the panel will cause the panel to increase in temperature, as it will with most surfaces. Secondly, free electrons that do not flow to generate electricity, after being excited by sunlight will actually release heat as they return to an unexcited state. Solar Panels.
