A 1KW system can generate about 5.5 units/day from Nov-Feb (not rainy, sunny but panels do not get very hot), about 5 units from March to June (not rainy, sunny but panels get very hot hence less efficiency) and 4 to 4.5 units from June to September (Monsoon season, panels get less sunlight, electricity production totally depends on clouds and amount of rain during this period) A 3KW system is the most efficient for a 2000 sq.ft house that uses more than 500 units/month. We custom design each solar power system after studying your electricity usage and the different electrical products used at your home/ business. We design your system in such a way that most of the electricity produced is used during the day itself. This requires less number of batteries and hence lower cost for the system and faster return on investment. We take care of everything for you starting from site inspection, design of your solar power systems, components procurement, shipping and installation. We provide 5 years of complete system warranty. During this time our technicians will visit your system proactively once in 3 months to check and maintain the system. Some of their tasks include cleaning the solar panels, refilling battery acid if required, checking the Inverter to make sure everything is fine, etc. We provide Annual Maintenance Contract (AMC) for a reasonable cost from 6th years onwards if you want to continue getting our service and support. Solar power systems are complex. A Solar Home is a Smarter Home.
