(Read more about Lithium batteries here)   People often claim that Lithium batteries are expensive, and although initial costs are higher, Lithium batteries are cheaper over a longer period. In this article, we will try and compare batteries that use Lithium Iron Phosphate (LiFePO4) chemistry with Lead-Acid batteries, in terms of capacity, longevity and price over an extended period of time. We will conclude that LiFePO4 batteries are about 40% cheaper in the long run, next to having a range of other benefits. We will...

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.

  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...

How you wire your panels impacts the performance of your system, and determines the choice of inverter and charge controller. First, let's remember that: W = V x A. The important difference between wiring panels in series or in parallel is that it affects the voltage and amperage of the resultant circuit. In a series circuit, you sum the voltage of each panel to get the overall voltage of the array. However, the amperage of the overall circuit stays the...
