Residential Rooftop Solar Solutions

The majority of people in India are used to power outages. There isn't a single state in the country where residents aren't subjected to power outages. The situation is even worse in rural areas, where power outages of several hours are common. Electrical outages occur as a result of the heavy load on the power grids, with even the largest metropolitan cities experiencing power outages, especially during the summer months. Many Indian households have built solar rooftop systems for their homes, seeing solar power as a stable and economically viable source of energy.

The financial component is the most compelling reason to install rooftop solar panels for your home. Solar energy has quickly established itself as one of the most promising and widely accepted renewable energy sources available today. Residential solar solutions can supply free, uninterruptible electricity for many years while also contributing to a cleaner environment. Solar rooftop systems for residential use are very simple to install and maintain. Excess electricity can be sold to the grid through a net-metering facility, that has a direct impact on current electricity bills. With decreasing fossil fuel supplies, accelerated environmental degradation, and pressure on power generation infrastructure, the government has taken a number of actions, including subsidies, to encourage the adoption of solar energy by providing residential solar solutions.


Solar power is widely recognised as the most realistic and reliable solution to reduce electricity bills while also contributing to a more sustainable environment. Solar rooftop systems for homes are best installed on homes with empty and underutilised rooftops that receive abundant of sunlight during the day. Choosing the correct solar plant for a residential house, on the other hand, might be difficult, especially for non-technical persons. Some basic procedures are outlined here to assist you in making an informed decision about rooftop solar panels for your home.

A roof's solar energy potential is primarily determined by the following factors:

At the location, there is the possibility of generating electricity: It is advisable to examine the possible generation capacity at the area before installing a solar rooftop system for your home. It's worth noting that the higher the number of sunny days, the higher the solar plant's yield, which improves the break-even period and ROI.

Availability of shadow-free locations: Another important factor to examine is whether or not shadow-free spaces are available. When a shadow falls over a solar panel, it causes that panel's energy generation to be disrupted, as well as the entire string's. Hot spots are created by shadows, and they can permanently harm a panel. Consequently, whether it is an RCC roof or a tin-shed roof, a shadow-free region is critical for a solar plant's optimal performance.

Orientation of the roof: The rooftop solar plant orientation plays a vital role in the power generation of a solar plant. In India, south-facing roof is an ideal orientation as India lies in the northern hemisphere, and this enables the solar plant to receive the maximum amount of sunlight as the earth rotates, thereby improving plant yield.


Residential solar plants are divided into three categories: on-grid, off-grid, and hybrid systems, each with its own set of characteristics, applications, and benefits. The type of solar plant adopted is determined by the desired purpose and current electricity-grid circumstances.

On-grid systems are those that operate without the use of a power grid. An on-grid solar system is linked to the main grid, ensuring that grid power is only used when the solar system is unable to meet demand. When production exceeds consumption, any excess energy produced can be exported to DISCOMs via net metering, resulting in money. This type of equipment is incredibly cost-effective and allows for significant electricity savings. This system is best suited to areas with few power outages and well-developed net-metering infrastructure and policies.

Off-grid systems: As the name implies, they are systems that are not connected to the main grid. It's a self-contained system that uses solar energy to power its batteries. The plant generates solar power, which is used to charge the batteries, which then power numerous applications around the house. When grid power is unavailable or highly unreliable, with frequent outages, off-grid systems are the best option.

Hybrid systems: A hybrid system combines on-grid and off-grid technologies. This type of device enables energy storage in batteries while also exporting excess power to the grid once the batteries have been fully charged. While it appears to be a win-win situation, a comprehensive cost-benefit analysis is recommended, as hybrid systems are more expensive to build than the other two types of systems.


The amount of energy that can be generated from a given rooftop is easily estimated by the amount of sunlight and the amount of space available. Aside from space, the load need of the home is the determining element for the size of a solar plant. A cost study should ideally be performed to identify the size of the installed system to meet the customer's energy needs while also exporting excess energy to save money.

Rooftop solutions in India provide a cost-effective and environmentally friendly power source that is gaining popularity by the day. With careful planning, installing a solar rooftop system can result in significant electricity cost savings and access to green power for up to 25 years.
