As a rule, any solar power plant, whether it is home or large industrial station, consists of the following elements:
1. Set of solar panels – their target is to convert sunlight into electricity.
2. Charge controller – serves for efficient battery charging or switching between power sources in use. The controller decides which energy source the system will use – sun, wind or public grid.
3. Batteries – required to store surplus electricity, for later use at night when solar panels are not working. In some cases there is no need to use batteries, for instance, in systems which use all electricity immediately it is inappropriate or too expensive to store power.
4. AC/DC Inverter – serves for converting direct current of solar panels or batteries into alternating current, used in most household appliances.
5. Other equipment – wires, connections, mounting brackets, temperature sensors, etc.
The right combination of these elements in accordance with the systems purpose is very important. The right configuration helps to boost the system’s capacity and reduce its cost.
Besides, in some cases you do not have to use a controller, invertor or batteries. For example, it makes no sense to store power and batteries are not required, when you have a large-scale solar energy production (for a factory or a small settlement), when all electricity is transmitted directly to public grid. The same is true for inverters — if you just need light in your garden or garage, you can do without inverters.
