Choose your system
On-grid, off-grid or hybrid?
The right plant type depends on your grid supply and how much backup you need.
| On-grid | Off-grid | Hybrid | |
|---|---|---|---|
| Best for | Homes and businesses with a regular grid supply | Remote locations or unreliable grid | Grid-connected sites that also want battery backup |
| Battery backup | Not required | Yes, bank sized to need | Yes |
| Net metering | Yes | No (no net-metering where there is no grid) | Yes |
| Equipment cost | Lower than off-grid | Higher (batteries) | Higher (batteries) |
| Note | Hedges against yearly tariff rise (avg. ~5%). Upgradable to hybrid | Customers size the battery bank as needed | On-grid system upgraded with a battery |
Rooftop vs ground-mounted
Rooftop
Ideal where open ground is scarce. An empty rooftop can be put to use for power generation, and rooftop installations are known to reduce leakages and improve insulation.
Ground mounted
Works well on large open space and can give significant long-term savings. Ideal for institutions and industries where captive consumption is high and open space is available.
Government schemes
Subsidy and scheme support
Central schemes can improve solar economics. Details change, so always check current guidelines before you decide.
PM Surya Ghar
A national scheme supporting rooftop solar for households. Applications go through the official national portal. We can guide you on eligibility and the paperwork for your home in Jaipur.
Official portalPM-KUSUM
For farmers: Component-A covers decentralised grid-connected solar plants up to 2 MW, Component-B covers stand-alone solar agriculture pumps and Component-C covers solarisation of existing grid-connected pumps. Redstar is currently executing several KUSUM Component-A plants.

FAQ
Questions we hear often
What is the difference between on-grid, off-grid and hybrid solar?
On-grid systems use net metering and suit places with a regular grid supply; they can be upgraded to hybrid with a battery. Off-grid systems include a battery bank and suit remote or unreliable-grid locations. Hybrid combines grid connection with battery backup.
Should I choose rooftop or ground-mounted solar?
Rooftop suits sites with little open ground and can reduce leakages and improve insulation. Ground-mounted plants suit institutions and industries with high captive consumption and open land available.
What does Redstar's EPC service cover?
Engineering design consultancy, equipment supply, civil planning, construction, erection, commissioning, training and management hand-over, with a single point of contact for the life of the system.
Do you provide maintenance after installation?
Yes. Our O&M services include preventive and corrective maintenance, inspection and testing, cleaning, repairs, replacements and training.
How long does a solar system last?
Solar systems offer a generation life of around 25 years, according to our brochure. Regular O&M helps keep output high.
Can I get a government subsidy?
Schemes such as PM Surya Ghar (for households) and PM-KUSUM (for farmers and solar pumps) may apply. Eligibility and amounts change, so we check current guidelines with you during the site survey.
Where do you work?
We are based in Jaipur and have completed projects in Rajasthan, Gujarat, Madhya Pradesh and Haryana, with plants and pump sets across Punjab, Maharashtra and Andhra Pradesh as well.
