I wonder, why are you delaying the solar installation for your home and business? The grid supplied electricity cost are increasing day by day and currently are at average 65-70 Rs per unit. Below simple calculation indicate reaching breakeven on solar investment with in approximately one year. 

• Initial Installation Cost (Irekmerx’s  designed basic solar energy system) : Rs 950,000.00 
• Cost of Annual Energy produced by solar :  936,000.00 (@ minimum 1200 Units per month production approximately)
• Maintenance Costs: Nil (one year free service by installer)

The system will recover its cost with in a year for you and the design life of the solar panels is 25-30 years. This means that it will keep on producing approximately Rs 900,000.00 of electricity for another 24 years. The maintenance costs if deducted as 10-15% per year ( approximately Rs 120,000 per year ) will still leave huge savings in terms of electricity bills. 

Seriously! think about it, and go solar now when the prices of solar equipment are all time low.
