Solar panels are often created from silicon, the same material used for transistors and in-built circuits. The silicon is treated or “doped” so as when sunlight hits it electrons are discharged, so producing electricity. There are three standard varieties of solar cell. Monocrystalline cells are derived from a silicon ingot grown from a single great crystal of silicon whilst polycrystalline cells are derived from an ingot made up of several more compact crystals. The third variety is the amorphous or thin-film solar cell.
Remarkable Characteristics of our Solar Panels are:
- Less Support
- Long Life
- Superior
- Contamination free
- Higher Efficiency
- Magnificent Toughness
A solar cell is an electronic component which directly transforms sunlight into electricity. Light source glowing on the solar cell generates both electrical as well as voltage to generate electrical energy. This process involves firstly, a elements whereby the absorption of light increases an electron to a greater electricity status, and secondly, the action of this superior energy electron from the solar cell into an outside circuit. The electron then reduces its energy in the circuit outlet and then returns towards solar cell. A variety of materials and operations could quite possibly accomplish the prerequisites for photovoltaic power process, having said that in process the majority of photovoltaic energy conversion process uses semiconductor substance in the form of a p-n junction.
So With the goal that, you can benefit as much as possible from your top space to generate fundamentally more power.
What is current?
Current is the flow of movement of Electrons.
We are measuring the current using Ammeter.
The Unit of current is Ampere
The Letter symbol is I
The flow of electrons towards the positive pole is current.
I = V/R ( v – voltage; I – current; R – Resistance)
The two types of current are AC(alternative current) and DC( Direct Current)
Alternative current is what we get in wall electrical outlet and it has 230 volt.
12 volt dc system is used in solar panels. DC is that what we get from solar cells, batteries etc..
Difference between AC and DC:
| Alternate Current | Direct Current |
|
Rectified output |
|
Only high volt shocking |
|
Terminals are Positive(+) and Negative(-) |
|
Usage in TV, Computer etc.. |
|
Current pass through semi conductor. |

Polarity must. |
What is Voltage?
The movement of force of electrons is called Voltage. The potential difference between two points, a factor that reduces the flow of electrons.
V = I X R ( V – Voltage; I – Current; R – Resistance)
Solar Panel Connecting Methods:
There are 3 types of Solar panel connecting methods.
- Serial Connection
- Parallel Connection
- Serial & Parallel Connection.
How to Connect Solar Panels in Series:-
Series Connecting – 24V System
By connecting solar panels in series it will increase voltage and current Amps will remain the same. To connect solar panels in series we have to connect plus + to – minus. See the picture for details. In this example we have connected 2 solar panels in series which give 24v output.
How to connect solar panel in parallel:-
Parallel Connecting – 12V system
Solar panel gives more current when they are connected in Parallel. And the voltage will remain the same. Parallel Connection is the best option as we do not need high voltage. To connect solar panels in parallel we have to connect plus to plus and minus to minus. See below diagram.
