Solar Panels / Modules & Regulators: from R 32.50 / Watt
The sun is a great source of energy and especially in Africa, we have the opportunities to convert that energy into electricity. By storing additional energy obtained from the sun during the day in a proper way, by charging batteries for example, we can have electricity 24 hours a day...
To convert the energy from the sun into electrical energy, we use solar panels / modules. The output from the panel / module is a DC open circuit voltage (typically around 21-22 Volt in our applications). When connected to a load, current starts to flow to the load and the voltage drops.
We need to calculate the load that will be connected to the system, before we can calculate the size of the solar system. It will not make sense to connect a 20 Watt solar system when we will be using a 200 Watt load. We must also note that we want to store energy (by charging a battery) to use when the sun is not available. Thus, in our calculations, we have to compensate for those dark hours as well.
For our applications, we will have solar panels connected to a solar regulator unit, which will control the charging to a battery to prevent over-charging the battery (as the voltage of most solar modules are around 17 V - 22 V)
