Frequently Asked Questions: 10kW Solar System in Hyderabad

Can a 10kW system power my entire 3BHK/4BHK flat in Hyderabad?

Yes, absolutely. A 10kW system generating 40-45 units daily can comfortably power:
2-3 split ACs running 8-10 hours
1 refrigerator, 1 washing machine
10-12 LED lights, 5-6 fans
Water motor, geyser, microwave, TV, and other appliances
If your current monthly consumption is 800-1,200 units, a 10kW system will cover 90-100% of your needs. Homes consuming 1,200-1,500 units will see 75-85% offset, still dramatically cutting bills.
The key is aligning your high-consumption activities (AC usage, washing machine, cooking) with solar generation hours (9 AM – 5 PM). With net metering, surplus power during the day credits your account for evening use.

How much roof space do I need for a 10kW solar system?

You’ll need 800-1,000 square feet of shadow-free rooftop area, depending on panel wattage:
High-wattage panels (540-550W): ~800 sq ft for 18-19 panels
Mid-wattage panels (450-500W): ~900 sq ft for 20-22 panels
Standard panels (330-400W): ~1,000 sq ft for 25-30 panels
Critical: The area must be shadow-free between 9 AM and 3 PM throughout the year. Even 10-15% shading from water tanks, lift rooms, or neighboring buildings can reduce output by 20-30%.
For Hyderabad homes, typical villa rooftops (30×30 to 40×40 ft) easily accommodate 10kW systems. Apartments with dedicated terrace access can also install, subject to society approval.
Roof Orientation Matters:
South-facing: Ideal (100% efficiency)
East/West-facing: 90-95% efficiency (acceptable)
North-facing: 70-75% efficiency (avoid if possible)
Mixed orientations: Use dual-MPPT inverters

Will my 10kW on-grid system work during power cuts?

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Will my 10kW on-grid system work during power cuts?

No, standard on-grid systems automatically shut down during grid outages for safety—this is mandatory under grid-tie regulations. When TSSPDCL/TSNPDCL power goes off, your system stops generating to prevent “islanding” (dangerous back-feeding into the grid that could harm line workers).
If you need backup power:
Option 1: Hybrid Solar System
Adds battery storage (5-10 kWh typical)
Works as on-grid when power is available
Switches to battery during outages
Additional cost: ₹1,50,000-3,50,000 depending on battery capacity
[Explore 10kW Hybrid Systems]
Option 2: Separate Inverter Battery
Keep your existing on-grid system
Install independent home inverter + battery
Less efficient but lower cost
For most Hyderabad homes where grid reliability is 95%+, pure on-grid is the economically optimal choice. Invest savings in quality components rather than batteries.

What maintenance costs should I expect after installation?

10kW solar systems are remarkably low-maintenance. Here’s the realistic annual upkeep:
Year 1-5:
Panel cleaning: ₹2,500-3,500/year (6-8 sessions)
Annual system health check: ₹1,500-2,000
Inverter monitoring (self-check via app): Free
Total Annual Cost: ₹4,000-5,500
Year 6-10:
Same cleaning schedule
Inverter warranty covers any failures
Possible cable/connector tightening: ₹1,000-1,500 (one-time)
Total Annual Cost: ₹4,000-6,000
Year 11-15:
Inverter replacement (if out of warranty): ₹70,000-1,00,000 (one-time in year 10-12)
Panel cleaning continues
Mounting structure inspection: ₹2,000 (one-time)
Year 16-25:
Panels still generating at 80-85% capacity
Second inverter replacement (year 20-22)
Minimal additional costs
Lifetime Maintenance Budget: ₹2,00,000-2,50,000 over 25 years Average Annual: ₹8,000-10,000
Compare this to ₹1.08 lakh/year in electricity savings—maintenance is just 7-9% of savings.

How long will it take to get subsidy after installation?

Based on current PM Surya Ghar implementation in Hyderabad:
Timeline:
Installation Completion: Day 0
Submit subsidy application through National Portal with commissioning certificate: Day 1-3
DISCOM verification (TSSPDCL/TSNPDCL): 7-15 days
MNRE approval & processing: 15-30 days
Direct Benefit Transfer (DBT) to bank account: 30-60 days total
Current reality in Hyderabad (as of December 2025):
Fast-track cases: 30-45 days
Average cases: 45-75 days
Delayed cases (documentation issues): 90-120 days
Pro tips for faster subsidy:
Ensure installer is MNRE-empanelled
All components must be ALMM-listed
Keep original bills, invoices, photos
Use only BIS-certified inverters
Complete application accurately (rejections cause 30+ day delays)
The ₹78,000 subsidy is directly credited to your bank account—not to the installer. Most installers require you to pay the full amount upfront and claim subsidy separately.
Alternative: Some installers offer “subsidy-inclusive pricing” where they adjust pricing and handle claims, but verify credibility before agreeing.

Is my rooftop strong enough for a 10kW solar system?

A 10kW solar system with mounting structure weighs approximately 600-750 kg total—about 60-75 kg per 100 sq ft, or the weight of one average adult per 10×10 ft area.
For Hyderabad buildings:
RCC Roofs (Most Common):
Load capacity: 200-300 kg/sq meter (standard construction)
10kW system load: 60-75 kg/sq meter
Verdict: Absolutely safe ✓
Asbestos/Metal Sheet Roofs:
Requires specialized lightweight mounting
Feasible with proper structural support
Consult structural engineer
Old Buildings (20+ years):
Professional structural assessment recommended (₹3,000-5,000)
Most pass with flying colors
If reinforcement needed: ₹15,000-25,000
Wind Load Consideration: Hyderabad occasionally experiences 60-80 km/h winds during storms. Quality mounting structures are engineered for:
Wind speed: 150 km/h (well above local maxima)
Uplift resistance: 2,400 Pa pressure rating
Anchoring: Expansion bolts into RCC
Your installer should provide a structural design certificate certifying compliance with IS 875 (Code of Practice for Design Loads).

Can I expand my system in the future if I buy an electric vehicle?

Yes, but with some considerations:
Net Metering Limit: Your net metering agreement allows capacity up to your sanctioned load. If your sanctioned load is 5 kW and you’ve installed 10 kW solar, you’re using 2x multiplier (allowed under TGERC rules).
To Expand:
Check current sanctioned load limit
If expanding beyond, apply for load enhancement with TSSPDCL/TSNPDCL
Pay load enhancement charges
Modify net metering agreement (₹500-1,000 fee)
EV Charging Requirements:
Typical EV (Nexon EV, Tata Tiago): 40 kWh battery
Daily charging need: 5-7 kWh (if driving 40-50 km/day)
A 10kW system already generating 40-45 units can easily absorb this
Better Approach: Instead of expanding, optimize charging timing:
Charge during peak solar hours (10 AM – 3 PM)
Your 10kW system can charge EV + run home loads simultaneously
Surplus solar goes to EV instead of export
For most Hyderabad EV owners, a 10kW system is sufficient for home + EV. Expand to 15kW only if:
You have 2+ EVs
Daily driving exceeds 100 km combined
You want faster charging speeds

What happens to excess electricity I generate?

Under Hyderabad’s net metering policy (TSSPDCL/TSNPDCL):
Monthly Settlement:
Your bi-directional meter tracks import (grid to home) and export (solar to grid) separately
Monthly bill shows: Units Consumed – Units Exported = Net Units
You pay only for net units
Example Month:
Solar generated: 1,300 units
Home consumed: 1,100 units
Surplus exported: 200 units
Grid imported (at night): 150 units
Net consumption: 150 – 200 = -50 units (credit!)
Bill: ₹0 (minimum fixed charges ₹20-50 apply)
Annual Reconciliation (April-March):
If you have annual surplus credits, DISCOM purchases at determined tariff
Typical rate: ₹3.00-4.50/unit (vs. retail ₹7-10/unit you save)
Credits expire at financial year end
Strategic Consumption: Maximize self-consumption during solar hours:
Run washing machine, dishwasher during day
Charge devices during peak sun
Pre-cool home with AC before evening
Heat water during solar hours
Target: 85-90% self-consumption, 10-15% export for optimal economics.

Making Your Decision: Is 10kW Right for You?

A 10kW on-grid solar system is ideal if:

✓ Your monthly electricity consumption is 800-1,500 units ✓ Your monthly bill is ₹6,000-15,000 ✓ You have 800-1,000 sq ft of shadow-free rooftop ✓ You plan to stay in the property for 5+ years (to fully realize ROI) ✓ You value energy independence and want to lock in electricity costs for 25 years ✓ You’re considering an electric vehicle in the next few years

Consider a Smaller System (5kW or 7kW) If:

Monthly consumption is 400-700 units
Rooftop space is limited (400-600 sq ft)
Budget is tighter (₹3-4 lakh after subsidy)
[Internal Link: 5kW Solar System Hyderabad]
[Internal Link: 7kW Solar System Hyderabad]

Consider a Larger System (15kW) If:

Monthly consumption exceeds 1,500 units
Large villa or multi-family property
Planning multiple EVs or high-power appliances

Consider Hybrid Instead If:

Frequent power cuts in your area
Critical loads requiring backup (medical equipment, home office)
Willingness to invest extra ₹1.5-3 lakh for batteries
