Overview of On-Grid
Solar Systems
An on-grid solar system, also known as a grid-tied solar system, is connected to the main grid. Many Indian households with a stable grid connection rely on on-grid solar systems for their electricity needs. At Klymate Technologies LLP, we specialize in installing on-grid rooftop solar systems for both individual homes and housing societies.
An on-grid solar power system for a home includes several components:
●Solar panels
●Solar inverter
●Mounting structures
●Bi-directional meter
●Solar accessories
Working of an On-Grid
Solar System
The electricity generation process in an on-grid solar system involves several steps to ensure your home remains powered day and night.
1. Solar Panels
Absorb sunlight and convert it into direct current (DC).
2. Inverter
Converts DC into alternating current (AC).
3. Bi-directional Meter
Feeds AC power to your home and manages the exchange of electricity with the grid.
4. Excess Electricity
Any surplus electricity generated is supplied to the grid.
5. Net Metering
At night or when needed, the bi-directional meter imports electricity from the grid.
Components of
Residential On-Grid
Solar System
1. Solar Panels
Installed on rooftops, solar panels face the south direction to maximize sunlight absorption and convert it into DC power.
2. Solar Inverter
Essential for converting DC power from the panels into usable AC power for household appliances.
3. Solar Mounting Structures
These support the solar panels, designed to withstand extreme weather and last for 25 years. They are rust-proof and precision-engineered for durability.
4. Solar Accessories
Includes AC and DC cables, DC combiner boxes for isolating high-voltage DC power, and AC combiner boxes for managing AC power from multiple inverters.
5. Bi-Directional Meter
Tracks electricity supplied to and imported from the grid, essential for the functionality of an on-grid solar system.
Net Metering in On-Grid
Solar Systems
Net metering tracks the electricity generated, consumed, supplied to the grid, and imported from the grid. At the end of each month, your electricity bill reflects the net units consumed, reducing your overall costs.
Benefits of Using an
On-Grid Solar System
●Trackable Electricity Generation: Easy to monitor the units generated.
●Simplified Billing: Understand your solar electricity bill effortlessly.
●Cost Savings: Significant reduction in monthly electricity bills.
●No Battery Requirement: Grid acts as a battery, eliminating replacement costs.
●Government Subsidies: Available for on-grid systems using DCR panels.
Types of On-Grid Solar
Systems by Capacity
The capacity of on-grid systems varies, and subsidies are available for different sizes:
●1 kW System: Produces about 1400 units/year, saving approximately ₹11,200 annually.
●2 kW System: Produces about 2800 units/year, saving approximately ₹22,400 annually.
●3 kW System: Produces about 4200 units/year, saving approximately ₹33,600 annually.
●5 kW System: Produces about 7000 units/year, saving approximately ₹56,000 annually.
●10 kW System: Produces about 14,000 units/year, saving approximately ₹112,000 annually.
Pricing and Subsidies
The cost of an on-grid solar system depends on various factors, including the type of panels, inverters, and mounting structures. The Indian government offers subsidies for residential installations using DCR panels, capped at ₹78,000 for systems above 3 kW.
Return on Investment
Investing in an on-grid solar system offers substantial long-term savings. For example, a 5 kW system can save approximately ₹56,000 annually, with the investment breaking even in about 4 to 5 years and continued savings for at least 20 more years.

Overview of an Off-Grid
Solar System
An off-grid solar system, also known as a standalone solar system, operates independently from the main power grid. It functions as a self-sufficient energy island, composed of the following components:
●Solar panels (modules)
●Mounting structures
●Batteries
●Solar charge controller
●Solar inverter
●Solar accessories
Off-Grid Solar
Components and Their
Functions
1. Solar Panels
Solar panels are composed of solar cells, which can be either monocrystalline (single silicon crystal) or polycrystalline (multiple silicon crystals). Both types capture sunlight and convert it into direct current (DC) electricity. For optimal performance, ensure the panels are installed without any shadow interference.
2. Solar Inverter
Since household appliances require alternating current (AC) power, the solar inverter plays a crucial role by converting the DC power generated by the solar panels into AC power. The inverter is the heart of the off-grid solar system.
3. Batteries
Batteries store the excess electricity produced during the day for use at night. During sunlight hours, the electricity generated by the panels powers the home, and any surplus is stored in the batteries.
4. Charge Controller
The charge controller manages the flow of electricity from the solar panels to the batteries and the inverter. It ensures the batteries are charged properly and prevents overcharging.
5. Mounting Structures
Mounting structures are essential for positioning the solar panels at the correct tilt angle to maximize sunlight exposure. High-quality, hot-dipped zinc galvanized structures provide durability and rust resistance.
6. Solar Accessories
Various accessories are necessary for a safe and efficient off-grid solar system, including:
●DC cables and combiner box
●AC cables and combiner box
●MC4 connectors
●Earthing strips and conduit trays
●Lightning arrester
Working of an Off-Grid
Solar System for Homes
The operation of an off-grid solar system is straightforward:
1. Solar Panels
Absorb sunlight and convert it into DC electricity.
2. Combiner Box
Collects DC current from the panels.
3. Charge Controller
Manages the flow of DC electricity, charging the batteries and supplying power to the inverter.
4. Batteries
Store excess electricity for use during non-sunlight hours.
5. Inverter
Converts DC power to AC power for household appliances.
6. Battery Management
Modern inverters include built-in battery management systems to ensure efficient energy use.
