Solar Panels for Rental Houses in India โ DCR vs Non-DCR Explained
Installing solar panels on a rental house is one of the smartest ways to reduce electricity bills and embrace renewable energy. However, before investing, itโs important to understand which solar system suits you best โ especially the difference between DCR and Non-DCR panels, and how subsidy eligibility affects your final cost.
At Synergy Solar Solutions, we simplify these details so that homeowners and residents of rental properties can make the most informed choice.
Can You Install Solar Panels on a Rental House?
Yes, you can install solar panels on a rental house โ with the permission of the property owner and the local DISCOM (Electricity Board).
If the property owner applies for installation and the electricity connection is in their name, the system qualifies for government subsidy (with DCR panels).
If the property is on rent and the installation is done without ownership rights, the system will not receive subsidy, even if DCR panels are used.
In short:
DCR panels with subsidy โ For property owners. No subsidy โ For rental property users.
What Are DCR and Non-DCR Solar Panels?
Solar panels in India are categorized based on where their cells and modules are manufactured.
DCR (Domestic Content Requirement) Solar Panels
Entirely made in India (both cells and modules).
Eligible for MNRE rooftop solar subsidy (only for property owners).
Slightly older technology โ mostly Poly or standard Mono panels.
Generates around 4 units per kW/day.
Higher initial cost, but the subsidy reduces overall price.
Non-DCR Solar Panels
Made in India using imported solar cells (mainly from China or Vietnam).
Not eligible for government subsidy.
Built with advanced technologies โ Mono-PERC, Half-Cut, and Bifacial.
Generates higher output (~ 4.5 units per kW/day).
Cheaper upfront cost, requires fewer panels, and offers same warranty as DCR.
Government Subsidy Eligibility
Under the National Portal for Rooftop Solar (NPRS) by MNRE:
Condition Subsidy Eligibility Owner installing on rooftop with DCR panels Yes Rental house user installing system No Non-DCR panels used No DCR panels used on non-owner property No Rooftop installation โค 3 kW 40 % subsidy Rooftop installation > 3 kW 20 % subsidy (for next 7 kW)
Therefore, if you are living in or managing a rental house, the subsidy benefit is not available, but you can still install an efficient Non-DCR on-grid system at a lower cost.

Even though DCR systems receive subsidy, the final cost and annual generation value are almost equal to Non-DCR systems. Non-DCR panels generate more electricity and require fewer modules, offering better efficiency for rental properties.
Which System is Best for Rental Houses?
For rental houses, the Non-DCR solar system is the most practical and affordable solution. Hereโs why:
No Subsidy Hassle: Non-DCR systems are free from government documentation and approval processes. Lower Upfront Cost: Even without subsidy, Non-DCR panels are cheaper. Higher Power Generation: Around 12 % more electricity than DCR panels. Fewer Panels Needed: Saves roof space โ ideal for compact rental rooftops. Same Warranty & Lifespan: 25 + years performance, 10โ12 years product warranty. Advanced Technology: Uses the latest Mono-PERC and Half-Cut cell technology.
So, for anyone installing solar in a rental property, a Non-DCR on-grid system offers the best mix of efficiency, flexibility, and ROI.
When Should You Choose DCR Panels?
If you are the owner of the rental house (not the tenant) and the electricity connection is in your name, installing DCR panels allows you to claim subsidy benefits.
Choose DCR when:
You own the property.
You plan long-term residence (10 + years).
You want MNRE subsidy through the National Portal.
Even though DCR uses slightly older technology, the subsidy brings the net cost close to Non-DCR systems.
Key Takeaways
Subsidy Eligibility: Only DCR panels used by property owners qualify.
Rental Houses: Non-DCR systems are recommended โ cost-effective and efficient.
Performance: Non-DCR panels produce โ 0.5 unit more per kW/day.
Panel Count: Non-DCR systems need fewer modules โ ideal for small rooftops.
Warranty: Both offer the same 25 + year performance guarantee.

For rural landowners and farmers in India, solar energy has emerged as a reliable source of passive income. Unlike traditional farming, which depends on crops, weather, and active labor, solar farming allows you to earn money consistently without daily involvement.
With government schemes like PM-KUSUM, rising energy demand, and the push for renewable energy, solar farming is now a profitable, low-risk investment for rural entrepreneurs.
What is Passive Solar Farming?
Passive solar farming means earning income from solar energy without managing daily operations. The main approaches include:
Leasing your land to a solar developer โ You receive fixed annual rent while the developer handles installation, maintenance, and power sales.
Power Purchase Agreements (PPA) โ You install solar panels (or fund a project) and sell electricity at a fixed rate to the grid or corporate buyers.
Participation under PM-KUSUM โ Government-backed scheme allowing farmers to set up small solar systems and sell surplus energy with minimal involvement.
This allows rural landowners to earn steady, long-term revenue without replacing their primary occupation.

Why Solar is the #1 Passive Income Source for 2026
Predictable ROI: Solar panels last 20โ26 years Low Maintenance: Minimal ongoing costs Government Support: Strong incentives & policies Eco-Friendly: Earn while reducing carbon emissions Scalable: Start small, grow over time
Solar energy isnโt just transforming how India powers its homes โ itโs also creating smart financial opportunities for individuals and investors. Today, you donโt need to be an industrial developer to make money from solar โ you can start small, invest wisely, and generate passive income from solar energy in India with minimal effort.
Here are the top 5 proven ways to earn solar income while contributing to Indiaโs clean energy mission.
1. Rooftop Solar Systems โ Save and Earn via Net Metering
A rooftop solar plant is the easiest way to earn passive income from solar energy right from your home or office. When your panels produce more electricity than you consume, the surplus is sent to the grid under Indiaโs net metering system.
Instead of direct payment, you receive energy credits that reduce your monthly bills. At the end of the financial year (AprilโMarch), these credits are adjusted by your electricity board.
Example: A 10 kW solar system can generate about 12,000โ14,000 units/year, saving around โน8,000โโน12,000/month depending on your electricity tariff.
Why itโs passive: Once installed, it runs automatically for 20โ25 years with minimal maintenance.
2. Community Solar Projects โ Earn Without Owning a Roof or Land
If you donโt have land or roof space, you can still earn passive income from solar projects through community or shared solar investments.
These are large solar farms where multiple individuals invest small amounts. The power generated is sold to industries or utilities through long-term PPAs (Power Purchase Agreements).
Typical Returns: 8โ12% per annum, depending on project tariff and location.
Why itโs passive: You donโt handle construction, operation, or maintenance โ the developer does everything, and you receive your share of revenue.
3. Agri-Voltaics โ Dual Income for Farmers
For farmers and rural landowners, agri-voltaic systems offer the best of both worlds โ solar power and farming together. Solar panels are mounted high enough to let sunlight reach the crops below, creating a hybrid setup that supports both food and energy production.
Income Potential: Farmers earn from both crop sales and solar energy generation under PPA or developer partnership models.
Why itโs passive: The solar plant is managed by a professional EPC or developer, while farming continues normally.
4. Solar Funds & Green Bonds โ Hands-Free Investment Returns
For investors who want passive income from solar power without owning or managing plants, solar funds and green bonds are smart choices.
These financial instruments pool investor money to fund multiple solar projects. In return, investors receive annual fixed returns โ usually between 8% and 12%, depending on the portfolioโs performance.
Why itโs passive: No operational involvement. Your money finances renewable projects, and you earn from their power sales.
Why itโs not โfixed incomeโ: Itโs still linked to solar project performance and portfolio returns โ not a contractual rent like leasing.
5. Solar Cooperatives & Local Energy Partnerships
An emerging opportunity in India is the formation of solar cooperatives โ groups of farmers, residents, or small businesses that jointly invest in solar power plants.
These cooperatives sell power to DISCOMs or local industries under group PPAs, sharing profits among members.
Average Returns: 8โ10% annually after operational costs, depending on the tariff and capacity.
Why itโs passive: Once the system is operational, management is handled by the cooperative board or partner developer.

High electricity costs and the rising need for sustainability have pushed homeowners, businesses, and communities to explore solar energy. But many hesitate because of the hefty upfront investment required to buy and install solar panels.
This is where solar leasing comes in โ a simple, affordable way to go solar without owning the system. In this guide, weโll explain what solar leasing is, how it works, the costs involved, and why it may (or may not) be the right choice for you.
What is Solar Leasing & How It Works
Solar leasing is a financing model where you rent a solar power system instead of purchasing it. The solar provider installs and owns the panels, while you pay a fixed monthly fee or a rate based on electricity generated.
How it works in practice:
The solar company designs and installs the system at zero upfront cost.
You pay a monthly lease fee (15โ25 years contract).
You consume electricity generated by the system, lowering your grid bill.
At the end of the lease, you can renew, upgrade, buy, or remove the system.
This makes solar accessible for households, SMEs, and institutions without requiring heavy investment.

Yet, signing a PPA is only the first step. Implementing it comes with hurdles that can delay projects, impact bankability, or reduce investor confidence.
This article explores the three most pressing challenges โ land acquisition, tariff disputes, and grid integration โ along with practical solutions and lessons for stakeholders.
Challenge 1: Land Acquisition & Aggregation
The Problem
Solar parks need hundreds to thousands of acres
Land in India is highly fragmented with multiple small owners
Issues include title disputes, unclear inheritance records, and local political resistance
Impact on PPAs
Delayed commissioning โ penalties for developers
Investor hesitation โ reduces fund flow into projects
Solutions
Employ professional land aggregators for legal due diligence
Digitize and modernize land records (via DILRMP) to streamline verification
Best Practice Example: Karnatakaโs Pavagada Solar Park, where land was leased from over 2,000 farmers, ensuring stable income for landowners and smooth aggregation for developers.
Challenge 2: Tariff & Pricing Disputes
The Problem
Developers & buyers often clash on tariff rates
DISCOMs sometimes attempt renegotiation when newer, lower tariffs emerge in auctions
Legacy PPAs at โน6โ7/unit face pressure in a market where auctions discover โน2.5โ3/unit tariffs
Impact on PPAs
Creates revenue uncertainty for developers
Erodes investor confidence in contract sanctity
May discourage long-term capital inflow
Solutions
Clear tariff clauses in PPAs, with strong legal safeguards
Encourage competitive bidding for transparent price discovery
Use escalation clauses (e.g. +2โ3% annually) to balance buyer and seller interests
Case Study: In Andhra Pradesh (2019), the state attempted to renegotiate existing PPAs to lower tariffs. This sparked legal disputes, delayed projects, and raised global investor concerns about Indiaโs contract stability.
Challenge 3: Grid Integration & Infrastructure
The Problem
Renewable plants are often located in remote, high-irradiation zones
Weak transmission networks, congestion, and curtailment limit power evacuation
Developers lose money when plants generate power but DISCOMs canโt (or wonโt) evacuate it
Impact on PPAs
Lost revenue despite signed contracts
Reduced plant load factor (PLF) and overall project IRR
Solutions
Invest in Green Energy Corridors and high-capacity transmission lines
Add compensation clauses in PPAs for grid curtailment
Promote hybrid models (solar + wind + storage) to balance supply and reduce grid stress
Other Critical Challenges
Payment Delays from DISCOMs
Many state utilities struggle financially
Developers face cash flow issues due to delayed receivables
Solution: Promote corporate PPAs with creditworthy buyers
Regulatory Uncertainty
Frequent state-level policy changes (e.g., open access surcharges, net metering caps)
Solution: Push for national-level standardization of open access and PPA frameworks
Contract Enforcement Issues
Buyers may delay compliance or seek early exit
Solution: Strengthen contract enforcement mechanisms via CERC/SERCs

The Road Ahead
Despite hurdles, PPAs remain the cornerstone of renewable growth in India. To fully realize the 500 GW target by 2030:
Transparent land processes must be implemented nationwide
Tariff stability should be ensured with robust, enforceable contracts
Grid modernization is essential to handle rising renewable penetration
If these systemic issues are addressed, India will not only accelerate its solar transition but also retain investor confidence โ ensuring PPAs remain the reliable engine driving clean energy growth.
