Residential Solar Projects
Most homes are suitable for solar panels, but factors such as roof orientation, shading, roof condition, and the amount of sunlight your location receives are important considerations. A professional site survey can help determine your home’s suitability.
On average, a 1 kW solar system requires approximately 10 square meters of shadow-free roof space. The total space depends on the size of the system needed to meet your energy requirements.
The cost varies based on the system size, location, and components (panels, inverters, structures, etc.). Typically, a residential solar system can range from ₹40,000 to ₹60,000 per kW. Government subsidies may reduce upfront costs.
Yes, solar panels can be installed on various roof types, including tiled and slanted roofs. Customized mounting structures ensure panels are securely installed at the optimal angle for maximum efficiency.
Payback periods typically range from 4 to 8 years, depending on system size, energy consumption, and electricity rates. After the payback period, the energy savings directly translate into financial benefits.
Yes, homes with solar systems often have higher resale values. Buyers are attracted to the prospect of lower electricity bills and environmental benefits, making solar a valuable investment.
Absolutely. Solar systems are modular, and additional panels can be installed as your energy needs grow. It's advisable to inform your installer about potential future expansion during the initial setup.
Solar systems require minimal maintenance. Regular cleaning of panels to remove dust and debris and annual checks by a professional for optimal performance are typically sufficient.
Solar panels generate electricity during the day. To use solar power at night, you can install a battery storage system (Off grid or Hybrid Solar Plant) to store energy.
Yes, most solar panels come with a 25-year performance warranty, while inverters typically have warranties ranging from 5 to 10 years.
On-Grid Solar Systems
An on-grid solar system is connected to the local electricity grid. It generates solar power during the day and supplies excess energy to the grid, allowing for net metering benefits.
Net metering allows you to export excess electricity generated by your solar system to the grid. The energy you supply is credited to your account and offsets the electricity you consume from the grid when solar power is unavailable.
No, on-grid systems automatically shut down during a blackout for safety reasons, as they are connected to the grid. To ensure backup power during outages, you can add a battery system.
- Lower electricity bills due to net metering.
- No need for battery storage, reducing initial costs.
- Environmentally friendly energy generation.
- Long-term financial savings and a shorter payback period.
No, batteries are not required for on-grid systems. However, if you want power backup during blackouts, batteries can be added to create a hybrid system.
Excess energy is exported to the grid and credited to your account. These credits can offset your electricity usage during times when your system isn't generating enough power.
Yes, in many regions, on-grid systems qualify for government subsidies, reducing the upfront cost. Check with your local solar provider for specific subsidy details.
Solar panels still generate power during cloudy weather but at a reduced efficiency. When the system doesn’t meet your energy needs, the grid supplies the shortfall.
Hybrid Solar Systems
A hybrid solar system combines the features of on-grid and off-grid systems. It is connected to the grid and includes battery storage, allowing you to store excess solar energy for later use, such as during power outages or at night.
During the day, the solar panels generate electricity to power your home. Excess energy is stored in batteries. Once the batteries are fully charged, any additional energy can be exported to the grid. At night or during blackouts, the stored energy in the batteries is used.
- Provides power backup during blackouts.
- Reduces reliance on the grid.
- Stores excess solar energy for nighttime use.
- Enables participation in net metering for additional savings.
Yes, hybrid systems are ideal for areas with unreliable grid supply as they provide uninterrupted power by using stored energy during outages.
Yes, an on-grid system can be upgraded to a hybrid system by adding compatible batteries and a hybrid inverter.
Lithium-ion batteries are commonly used in hybrid systems due to their high efficiency, long lifespan, and compact design. Lead-acid batteries are also an option but are less efficient and require more maintenance.
The cost of a hybrid system is higher than on-grid systems due to the addition of batteries. Prices vary depending on the system size, battery capacity, and other components. Typical costs range from ₹0.8 lakh to ₹1.2 lakh per kW.
The payback period is typically longer than on-grid systems, ranging from 6 to 10 years, depending on electricity rates, energy savings, and battery usage.
Yes, but this depends on the battery capacity and the load requirements of your home. Critical appliances can be prioritized for backup power to maximize efficiency.
Hybrid systems require minimal maintenance. The solar panels should be cleaned regularly, and the batteries should be checked periodically for performance and efficiency.
Yes, most hybrid systems are modular and can be expanded by adding more solar panels or batteries as your energy needs grow.
In some regions, hybrid systems qualify for subsidies. Check with your local solar provider or government agency for eligibility and details.
Yes, hybrid systems can function as off-grid systems by relying solely on solar panels and battery storage. However, grid connection is recommended for additional flexibility and reliability.
Commercial and Industrial (C&I) Solar Plants
A C&I solar plant is a large-scale solar energy system designed to meet the electricity needs of businesses, factories, warehouses, and other commercial or industrial facilities.
- Reduces electricity bills significantly.
- Provides energy independence and protection from rising energy costs.
- Enhances sustainability and reduces carbon footprint.
- Improves brand reputation through green initiatives.
The size depends on your facility's energy consumption, available roof or ground space, and your budget. A professional energy audit and site survey can help determine the optimal system size.
Solar energy is generated during the day. To power operations at night or during low sunlight, you can install battery storage or rely on the grid as a backup.
Costs vary based on the plant size, location, and system type. Typically, a C&I solar plant costs ₹30,000 to ₹50,000 per kW. Larger plants may have lower per-kW costs due to economies of scale.
The payback period ranges from 3 to 6 years, depending on your electricity savings, system size, and financial incentives like subsidies or tax benefits.
Yes, C&I solar plants can be installed on rooftops, parking lots, or ground-mounted depending on the available space and energy requirements.
Yes, many governments provide subsidies, tax benefits (like accelerated depreciation), and net metering policies to encourage solar adoption. Check your local regulations for eligibility.
Yes, if net metering or similar policies are available in your region, you can export excess electricity to the grid and earn credits or revenue.
- Regular cleaning of solar panels to remove dust and debris.
- Periodic inspection of inverters and electrical connections.
- Monitoring system performance through software to identify issues early.
Solar panels typically last 25-30 years with minimal degradation. Inverters and batteries, if included, may need replacement every 5-10 years.
Yes, solar systems are modular and can be expanded by adding more panels or upgrading components as needed.
- On-grid: Connected to the electricity grid, with no battery storage.
- Off-grid: Independent from the grid, using batteries for storage.
- Hybrid: Combines on-grid and off-grid features, with optional battery backup.
- Financing options include:
- Capital purchase (outright ownership).
- Solar loans.
- Power Purchase Agreements (PPA).
- Operating leases.
No, installation is planned to minimize disruption. For rooftop systems, construction activities are managed to ensure safety and minimal interference with daily operations.
Solar panels come with a 25-year performance warranty, while inverters typically have 5 to 10 years. Installation warranties and additional guarantees for batteries or other components may also be offered.
Most systems include monitoring software or platforms that allow you to track energy production, consumption, and overall system performance in real time.
