Roof Top Solar Electrification for Home and Office

Installation of off grid solar power plant to generate electricity for onsite consumption.


Installed 1KW solar Plant @ Chitradurga ,Karnatakla

Roof Top Solar Electrification for Home and Office, We shall conduct a detailed site visit with specialists to take accurate measurements, photographs and other site specific information for full design Prepare full system design to include civil, structural, electrical and mechanical components with construction drawings and specifications Procure equipment and materials deliver to site perform complete system installation Test all electrical components in accordance with manufacture instructions Commission the system to full operation.

Minimum Requirements:

  • Minimum 15 square meter shade free area for installing 1 kWp Solar panel array.
  • Suitable space for accommodating battery and inverter is required near to the module structure. (i.e. about 2 m2 covered, ventilated area with restricted access)
    The system will be in the off-grid mode with some battery backup. 
  • The electricity generated (approximately 4 units per 1 kWp system per day) is to be used for internal consumption (that is, not for export to grid).
  • The expected life span of the system (except battery) is around 25 years with proper maintenance.

Project Details

The proposed Roof Top solar Photovoltaic Power Plant would utilize vacant area of about 100 Sq.feet available on the terrace of the building. The proposed SPV power plant is estimated to afford annual feed of 1.7MWh , considering efficiency of the solar modules as 16 % , Power conditioning Unit (PCU) as 94 % and losses as 3 %
in the DC and AC system. The Plant would operate at an annual capacity utilization factor of 19 %. Solar Photovoltaic system consists of solar PV modules in series and parallel connections, these convert solar radiations into DC electrical power at the predetermined range of voltages whenever sufficient solar radiation is available. The amount of power they produce is roughly proportional to the intensity and the angle of the light reaching them. They are therefore positioned to take maximum advantage of available sunlight within siting constraints.
Off Grid Roof top solar system generally comprises the following main equipments

Solar PV System, Power Conditioning Unit, Battery
