Introduction: Stop Guessing Your Solar Requirement

If you are planning to install solar, the first question is always: how much solar do I actually need?

Most homeowners and businesses in Maharashtra either overspend on oversized systems or install smaller systems that don’t meet their needs. With rising electricity costs and increasing interest in solar subsidy in Maharashtra, making the right decision has never been more important.

The good news? You don’t need to guess anymore.

You can now calculate your exact solar requirement based on your electricity consumption along with roof space and potential savings in just seconds.

Step 1: Enter Your Monthly Units (Use This Calculator)

Instead of relying on assumptions, simply enter your monthly electricity units here:

What you’ll get instantly:

• Required solar system size (kW)
• Approximate roof area needed (sq. ft.)

This tool is especially useful for homeowners in Pune, Mumbai, Satara, and across Maharashtra looking to maximize benefits under the government solar subsidy scheme.

Step 2: Understand the Basic Calculation (Units → kW)

Here’s a simple way to estimate your requirement:

Rule of thumb:

• 1 kW solar system generates ~120 units/month (average)

This estimation helps you understand your requirement before applying for solar panel subsidy Maharashtra schemes.

Step 3: How Solar Subsidy in Maharashtra Impacts Your System Size

The central government solar subsidy under schemes like PM Surya Ghar primarily applies to residential rooftop systems.

Key points:

• Subsidy is based on system size (kW)
• Higher system size ≠ higher benefit beyond certain limits
• Proper system sizing ensures maximum ROI

Example:

Scenario:

• Monthly consumption: 300 units
• Required system: ~2.5 kW

Without optimization:

• You install 4 kW → higher cost, limited extra subsidy

With correct sizing:

• You install 2.5–3 kW → optimal cost + maximum subsidy utilization

Step 4: Roof Space Matters More Than You Think

One of the biggest concerns is space.

Approximate requirement:

• 1 kW = 80–100 sq. ft.

Factors affecting roof space:

• Panel efficiency
• Tilt angle
• Shadow-free area
• Structure type

This is why using a calculator is critical; it aligns your roof capacity + consumption + subsidy eligibility.

Step 5: Government Process & Solar Panel Licensing in Maharashtra

Many people think subsidy is automatic, but it’s not.

To claim benefits under Maharashtra government solar subsidy and central schemes, you must follow a proper process:

Key steps:

1. Vendor selection
2. Application submission
3. Net metering approval
4. Installation
5. Inspection
6. Subsidy disbursement

Important Note

S’unlimited solar does not provide subsidies directly.

Instead, they:

• Handle documentation
• Manage approvals
• Ensure smooth processing
• Help you claim eligible subsidy

This is crucial because many applications get rejected due to incorrect filing.

Step 6: Common Mistakes People Make

Avoid these mistakes when planning solar:

• Choosing system size without checking units
• Ignoring roof space constraints
• Assuming subsidy applies to all system sizes
• Not following proper solar panel licensing process
• Working with unverified vendors

Real Example (Maharashtra Homeowner)

Location: Pune

• Monthly bill: 350 units
• Calculator result: ~3 kW system

Result:

• Optimal system installation
• Eligible subsidy claimed
• 80–90% bill reduction

• Avoid overspending
• Get accurate system size
• Understand roof requirements
• Estimate savings
• Plan subsidy effectively
