A residential solar rooftop system uses solar panels installed on a home’s roof to generate clean electricity from sunlight, reducing electricity bills and environmental impact. These systems convert solar energy into power using components like photovoltaic (PV) modules, an inverter, and a mounting system. They can be grid-connected, feeding excess power back to the grid, or off-grid, using batteries to store energy for use at night.
Choosing a residential solar rooftop system offers numerous benefits, from long-term financial savings and energy independence to positive environmental impacts. By harnessing the sun’s power, homeowners can significantly reduce or even eliminate their electricity bills and contribute to a more sustainable future.
On-Grid System :
Excess electricity generated by the panels is sent to the electricity grid.
Off-Grid System :
Uses batteries to store electricity for later use, independent of the grid.
Hybrid System :
Combines elements of both, able to store energy in batteries and connect to the grid for added reliability.
Benefits Of Solar System
Financial benefits
- Reduced electricity bills : You can produce your own clean electricity, reducing the amount of power you need to purchase from the utility company. In some cases, with a proper system, you can see a reduction of 90% or more on your monthly bills.
- Long-term investment : While there is an initial upfront cost, a solar rooftop system is a long-term investment. Most systems have a payback period of around 3 to 7 years, and panels have an average lifespan of 25 to 30 years, resulting in decades of reduced energy costs.
- Increased property value : Homes with solar panel installations are often more attractive to buyers and can sell for a higher price. The added value is due to the lower energy costs and the appeal of sustainable living.
- Government incentives and net metering : Many governments offer incentives like tax credits, rebates, or subsidies to lower the installation cost. Net metering programs allow you to sell excess electricity back to the grid, earning credits that can further reduce your electricity bill.
Environmental benefits
- Reduced carbon footprint : By using a clean, renewable energy source, you can significantly reduce your household's greenhouse gas emissions and reliance on fossil fuels.
- Lower environmental impact : Unlike traditional power generation, solar energy systems produce no air pollution or direct greenhouse gas emissions during operation.
- Sustainable living : Installing solar panels is a tangible way to contribute to a cleaner, greener environment and promote sustainable energy practices.
Practical benefits
- Low maintenance : Solar panels have no moving parts and require minimal maintenance, usually just occasional cleaning. Many manufacturers offer warranties of 25 years or more, ensuring long-term reliability.
- Utilizes unused space : Rooftop solar systems make use of the underutilized space on your roof to generate electricity.
- Scalable design : The system can be designed to meet your household's current energy needs and can be scaled up as your needs evolve over time.
Components in the residential solar rooftop systems
Amongst the 3 types of solar roof top system, On-grid/Grid connected system is highly preferred especially in Indian Government schemes such as “Pradhan Mantri Surya Ghar Yojna” which provides subsidy to customers up to Rs. 75,000 for 3KW system.
The Key Components in the Solar Rooftop System Includes:
PV Module (Panel)
Our TOPCon panels are made with precision manufacturing with our 100% fully automatic is equipped with high standard material & has tie-up with one of the best suppliers for the respective components with assurance of good quality.
Solar Inverter
Sudarshan Saur’s solar PV systems are equipped with a smart inverter system that ensures efficient conversion of direct current (DC) to alternating current (AC), optimizing energy usage. The system includes real-time monitoring capabilities, supported by a dedicated team that provides continuous performance tracking, instant fault detection, and remote diagnostics. Customers also receive detailed generation reports, offering transparency and insights into system performance.
Mounting Structure
The mounting structure is made from high-grade galvanized steel with a coating of GI 120 GSM, ensuring durability and corrosion resistance. It uses high-tensile strength stainless steel (SS) bolts for secure and long-lasting assembly. Additionally, it complies with all relevant industry standards, ensuring safety, reliability, and performance.
AC Distribution Box
DC Distribution Box
The DCDB is used to manage and protect the DC side of the solar system—between the solar panels and the inverter. Combines multiple strings of solar panels. It also provides overcurrent protection using DC fuses or MCBs. It Includes surge protection devices (SPD) to guard against lightning or voltage spikes and facilitates isolation of the solar array for maintenance or fault handling.
DC Cables and AC Cables
Generation Meter
A generation meter in a solar photovoltaic (PV) system is a specialized energy metering device that records the total amount of electricity generated by the solar array. Its primary purpose is to monitor and quantify the energy output from the solar inverter, enabling accurate performance tracking and system evaluation. This data is essential for verifying the efficiency of the solar installation and is often used for billing and crediting purposes under net metering or feed-in tariff schemes. Functionally, the generation meter provides real-time and cumulative energy readings, supports communication interfaces for remote monitoring, and ensures compliance with utility regulations. It is typically installed between the inverter and the grid or load connection point, and must be tamper-proof and certified for accuracy to meet the standards set by local distribution companies and energy authorities.
Net Meter
A net meter is a specialized energy meter used in grid-connected solar PV systems to measure the bidirectional flow of electricity between the solar installation and the utility grid. Its primary purpose is to facilitate net metering, a policy mechanism that allows solar system owners to receive credit for the excess electricity they export to the grid. The net meter records both the energy consumed from the grid and the energy sent back to it, enabling accurate calculation of the net energy usage. This helps reduce electricity bills and promotes efficient energy use. It is typically installed at the point of interconnection between the solar inverter and the grid supply line, and must be approved and calibrated by the local distribution company (DISCOM).
Earthing Kit
This helps protect both personnel and equipment from electric shock and fire hazards, while also ensuring system stability and performance by maintaining consistent reference voltage levels. Functionally, the earthing kit facilitates grounding of PV modules and mounting structures to prevent potential differences and maintain equipotential bonding across the array. It also provides dedicated earthing for inverters and electrical panels, protecting sensitive electronics from transient voltages.
Lighting Arrestor
A lightning arrestor in a photovoltaic (PV) system serves as a critical protective device that safeguards electrical components such as solar panels, inverters, and distribution boxes from damage caused by lightning-induced surges. It functions by safely diverting the high-voltage surge energy to the ground, thereby preventing it from entering and damaging the system.
