Solar wire can play a key role when setting up solar energy properly.

Solar wire types, also known as solar panel wires or photovoltaic (PV) wires, refers to the type of wires/cables required to connect your solar panels with the rest of your photovoltaic systems.

Choosing a wire that is too small for your PV system results in your battery bank not charging fully. As a result, your appliances may not work fully.

Electrical and solar panel wires normally are grouped using the same criteria, mainly by conductor types

Those made up of a single metal wire core are single stranded conductors and those with multiple wire cores type are multiple conductors.

10 Best Solar Wire Products Reviewed And Rated

What you should know when choosing the right wire size

Wires used in solar systems are rated by their Amp.

The higher the current of your solar system is, the thicker the pv required for proper functioning of the entire system.

The currents and voltages of your solar energy system, will determine the size of wires you buy.

Significant voltage drops, will occur resulting in significant energy losses, as well as overheating that can cause a fire.

You can use a Solar Wire Size Calculator to select the proper wire for your needs.

The thicker the wire, the easier it will be for larger electrical currents to flow in it.

Therefore, short wires with large cross-sectional areas have a small electrical resistance that results in small voltage drops.

Solar wire thickness:

The thicker a pv wire is, the higher the cost and the opposite is also true for thinner wires.

This is because, thicker wires are capable of handling more amps.

When choosing the thickness of your wires, you can go either of these two ways.

A little thicker for safety, or just thick enough but vulnerable to sudden power surge.

To make a great choice, it’s advisable to buy a solar panel wire that is big enough to deal with the biggest current (amp) drawing appliance you have, and using that wire for all the other runs to the AC breaker panel.

PV wire length:

It’s important to consider the length of your solar wires.

Longer than average PV wire connecting high current appliances, needs a wire with more amps.

Longer wires need a high amp rating, so consider going for a little thicker wire.

Also, thicker wires would cushion high current appliances, that you will probably buy in the future.

There is a 0% harm of preparing for the future early, especially when it will save you from having to upgrade to thicker wires.

It’s also imperative to keep in mind that it’s wiser and less costly, to try and use solar panel wires that are shorter in length, than to have to buy very thick (and expensive) wire to compensate for unnecessary length.

Consider consulting a certified electrician to make sure you have chosen the best types of solar wires.

How are solar panels made?

This is a question that crosses the mind of many solar energy users.

Solar is now in the mainstream as the world’s cheapest energy source.

The fact that solar energy is very efficient, and a source of “green” energy makes people want to know and comprehend how solar energy systems work, how they are made and what the parts of a solar panel are.

Monocrystalline, polycrystalline, or thin-film (“amorphous”) silicon are some of the materials used to make solar panels.

Interested in making your own solar panel?

If you are considering having a solar panel that is self-made, then consider some factors such as the longevity of its output, efficiency and the overall cost.

How to economically and efficiently use of your solar energy:

1. Make sure you reduce the electricity consumption of your building.

Eliminate devices and appliances that consume too much of electricity.

2. Install LEDs in place of light bulbs. 90 % of energy is lost as heat with the light bulbs.

This is because light bulbs are based on glowing filament made from tungsten.

The modern LEDs make use of more than 90% to produce light.

3. Turn off standby mode.

Many electrical devices consume electricity even when they are not in use.

Many of this tip are found online and can help you save your solar power to a great extent
