Beginner level, Solar panels -

  Solar panels come in many different types, but the most important categories are mono-crystalline solar panels (mono) and polycrystalline solar panels (poly).   In many ways, they are the same: - Both panels capture energy from the sun and turn it into electricity - Both are made from silicon - Both are often made by the same manufacturers - Both can be good choices - Both have a long life span   There are a few key differences however. Mono-crystalline solar panels have solar...

  The general notion is that North-facing solar panels (in the Southern Hemisphere) is the most effective way of mounting solar panels. Have you ever considered mounting your panels East & West? Source: solarquotes.com.au   Roof orientation The direction of your panels in relation to the sun, also referred to as the Azimuth angle, is important for the amount of sunshine that your solar panels will receive over the course of the day.   The best way to determine the direction...

Advanced level, Cables, DC, Sizing -

Choosing the right wire sizes in your Solar PV system is essential for both performance and safety reasons. If the wires are undersized, there will be a significant voltage drop in the wires resulting in substantial power loss. Also, if the wires are undersized, there is a risk that the wires may heat up to the point in which a fire may result.

Advanced level, Batteries, Cables, DC, How to connect, Parallel vs Series -

  At the heart of any solar PV system sits the battery bank; the battery bank can be either a single or multiple batteries connected to each other.   Batteries are connected to each other in order to increase:   - the battery voltage (in Volts, V), or- the battery capacity (in Ampere hours, Ah), or- both capacity and voltage.   (Always remember power = Volts x Ampere, or W = V x A).   You can connect batteries either...
