Essential Solar Installation Knowledge for Homeowners


Understanding Sri Lanka's Solar Potential


Sri Lanka enjoys exceptional solar conditions that make it ideal for solar energy

  • High Solar Irradiance: Average 5-6 kWh/m²/day across most regions

  • Year-Round Sunshine: 1,700-2,200 sunshine hours annually

  • Consistent Climate: Relatively stable solar production throughout the year

  • Regional Variations: Northern and eastern regions typically receive more sunlight

  • Monsoon Considerations: Western and southwestern regions face slightly reduced output during monsoon seasons


Sizing Your Solar System Correctly


The right system size is crucial for optimal performance and return on investment

  • Average Home Requirement

A typical Sri Lankan home needs 3-5kW system

  • Calculation Method

Based on analyzing your past 12 months of electricity bills

  • Future-Proofing

Consider upcoming additions like air conditioning or electric vehicles

  • Space Requirements

Each 1kW typically requires 6-7 m² of unshaded roof space

  • Optimal Orientation

North-facing installations perform best in Sri Lanka

Understanding Solar Economics in Sri Lanka

Initial Investment: Rs. 175,000-200,000 per kW for quality installations
Return On Investment: Typically 4-6 years payback period
Savings Potential: 80-100% reduction in electricity bills
Property Value Increase: Homes with solar typically command 3-4% higher resale values
Financing Options: Various banks offer special green energy loans with favorable terms

Key Installation Considerations

Roof Condition: Your roof should be in good condition with 15+ years of life remaining
Roof Structure: Different mounting solutions for tile, metal, flat concrete, or asbestos roofs
Roof Orientation: North-facing is ideal, but east/west orientations still perform well
Shading Analysis: Professional assessment prevents performance issues
Electrical Infrastructure: Your existing electrical panel may need upgrading
Local Permits: CEB/LECO approval required before installation begins
Installation Timeline: Typically 3-7 days depending on system size and complexity

Comparing Solar Panel Technologies

Monocrystalline: Higher efficiency (20-22%), better performance in limited space, premium price
Polycrystalline: Good efficiency (15-17%), excellent value, slightly larger footprint
Bifacial: Collect light from both sides, ideal for reflective surroundings, 10-15% additional output
Half-Cut Cells: Better performance in partial shade, reduced heat losses
PERC Technology: Enhanced light absorption, improved performance in hot conditions


Inverter Technology Selection

String Inverters: Most economical, ideal for unshaded installations, 8-12 year lifespan
Microinverters: Best for partially shaded conditions, longer warranty (25 years), higher cost
Hybrid Inverters: Allow battery integration, essential for backup power
Power Optimizers: Balance between string and microinverters, excellent shade tolerance


Battery Storage Options

Lithium Iron Phosphate: Longest lifespan (10+ years), excellent safety profile, higher upfront cost
Tubular Lead Acid: Lower initial cost, 5-7 year lifespan, requires maintenance
Capacity Sizing: Typically 5-10 kWh for backup of essential loads
Depth of Discharge: Lithium batteries offer 80-95% DoD vs. 50% for lead acid
Cycle Life: Critical for longevity (6,000+ cycles for quality lithium batteries)

Our Solar Installation Options

On-Grid Solar Systems

Our on-grid solar solutions connect directly to the utility grid (CEB/LECO), allowing you to:

  • Generate your own clean electricity

  • Potentially reduce your electricity bills to zero

  • Sell excess power back to the grid

  • Benefit from various government schemes

  • Available CEB/LECO Schemes:


Net Metering - Pay only for the net electricity consumed. Excess generation carries forward to future months.


Net Accounting - Receive payment at Rs.37.00 per unit for excess electricity supplied back to the grid.


Net Plus - Get paid for all electricity generated, regardless of consumption. Separate meters track import and export.



Off-Grid Solar Systems

Our off-grid solutions provide complete energy independence without connection to the utility grid:

  • Generate and store your own electricity

  • Reliable power in areas with poor grid connection

  • Protection against power outages

  • Complete energy autonomy

Key Components:

Solar panels - (Trina Solar/JA Solar/Longi Solar/Jinko Solar/Ulika Solar)
Inverters - (Foxess, Huawei, Solis, Solax, PowerMr, ABB, Fimer)
Battery bank - Lithium Iron
Charge controllers
German switchgears and DC cables


Hybrid Solar Systems


Get the best of both worlds with our hybrid solar solutions:

  • Connect to the grid while maintaining battery backup

  • Seamless power switching during outages

  • Store excess power for nighttime use

  • Optimize energy efficiency and saving
