What we should know before buying solar system?
Solar energy is a type of energy which is directly obtain from sun in radiation form and convert it into electric power. Basically, solar system is the integration of many solar panels which works on the principle of “conservation of energy”. Energy can be converted from one form to another form. There are multiple categories of energy which are the fundamental to running machineries.
What is solar panel?
Solar panel is the composition form of multiples photo Voltic cells which convert light emery/sun radiation energy into (DC) electricity, this process is known as photovoltaic effect.
There are three basic types of solar panel, we should know about before buy solar system because it can affect output power production and efficiency.
• Monocrystalline
• Polycrystalline
• Thin film solar panel
| SOLAR PANEL TYPES | EFFICIENCY | COLOR | ADVANTAGES | DISADVANTAGES |
|---|---|---|---|---|

Low price
Good performance than thin film system |
Sensitive to high temperature
Not pure silicon based
Less efficiency than mono panel. |
Thin film |
8~10 |
Dark blue |

Un-suitable at home installation |
Which are the types of solar system?
There are three types of solar system:
• On-grid solar system
• Off-grid solar system
• hybrid solar system
| On grid-solar system | Off- grid-solar system | Hybrid solar system |
|---|---|---|
No need of batteries |
Required batteries to store energy/electricity |
Composition of on- grid and off- grid system |
Connected to public electricity |
Not connected, it just stores by batteries |
Can store as well transfer to grid. |
Net meter is used |
batteries use |
Net meter +batteries bot is installed in hybrid. |
Initially low investment price |
Comparatively high price |

On-Grid solar system
It is also called grid tied solar system. On-grid solar system is system which is connected from electricity electric wires or grid connected system. We can install it where already electricity have been supplying from transformer otherwise we cannot uses this system but can use off-grid system instead of it.we are used net meter in on grid system for reading extra units that are supplying to the grid. On grid system convert energy through solar panels and transfer to AC inverter, where current convert from Dc ~ AC because our home appliances such as fan, tv, refrigerator works on AC current, where it further shifted to home and grid station. Extra power that is produced during this process transfer to grid and required shifted to home. For example, a solar system produces 10kwh electricity and our home requirement is just 5kwh then remain extra 5kwh electricity send to electricity where it will make huge reduction in our electricity bill and our electricity bill may be in credit or negative from electricity.
Off-grid solar system.
In this system we are not connected to grid while we are used batteries to store excessive power produced by solar system. Off- grid solar system particularly used in those areas where access of grid is not available or reliable, where the long hour’s electricity shut off. The components used in this system are: Solar panels, inverter, batteries, wiring and mounting system with monitoring device.
Hybrid solar system.
A hybrid solar system is the combination of solar panels with another source of electricity generation or storage to improve reliability and efficiency. Each type of hybrid solar system has its advantages and is chosen based on factors such as location, energy requirements, reliability needs, and cost considerations. The goal of these systems is typically to maximize energy efficiency, reliability, and sustainability while reducing dependence on traditional fossil fuels.
What is 5kwh solar system?
5Kwh is a suitable system for homes, it is capable of producing more than 20~22 kwh of electricity within 24 hours. We can run these appliances:
• 2 Inverter Ac
• 5 led lights
• 6 led lights
• 1 refrigerator
But all appliances simultaneously running may not feasible.
Overall solar energy system (SES) is the clean, green and renewable energy system. Initially it is expensive but in long-term it has huge advantages. SES overcome the dependency on grid and provides hug cut-off from electricity bills. In this era many advanced solar systems are available in market than can generate electricity in cloudy and night conditions so we should buy a research based solar system because we know CHOOSE WISELY LIVE WELL
