It will take about 30-45 Days depending on size of the plant. Less than 10 KW systems can be installed within 45 weeks.

Various advantages accompany the adoption of a solar rooftop system, including diminished electricity expenses, potential tax benefits, and incentives from the government. Additionally, it allows for a reduction in carbon footprint, making a positive contribution to a cleaner environment.

Experience nearly cost-free power for a quarter-century. Mitigate the impact of rising electricity rates from DISCOMS. Contribute to a cleaner, greener environment by reducing carbon emissions. Benefit from the decreasing costs of Solar PV Panels. Enjoy the simplicity of installation and the advantage of not needing additional land.

In a grid-connected rooftop or small Solar Photovoltaic (SPV) system, the direct current (DC) power produced by the SPV panel undergoes conversion to alternating current (AC) through a power conditioning unit. The converted AC power is then supplied to the grid, either through a 440/220 Volt three/single-phase line or a 33 kV/11 kV three-phase line. The choice depends on the system’s capacity, whether installed in a residential complex, institution, or commercial establishment, and the regulatory guidelines established by individual states.

These systems operate by generating power during daylight hours, effectively utilizing it to meet internal energy needs and supplying any excess power to the grid, provided the grid is operational. During periods of insufficient solar power, such as due to cloud cover, the system seamlessly switches to drawing power from the grid to meet the captive loads.

Certainly, it’s noteworthy that in Haryana, there’s a mandate for the installation of solar rooftop systems in various types of buildings. This requirement encompasses commercial buildings, schools, hospitals, offices, factories, and residential premises larger than 500 square yards. It reflects a proactive step towards sustainable energy practices. It’s worth keeping an eye on developments in other states, as similar mandates are likely to become more common, aligning with the broader trend towards promoting renewable energy adoption.

There is a provision of Central Financial Assistance of 30% of the total cost or Rs. 12 to Rs. 18 per watt or Rs. 1.20 crore per MWp under the Grid Connected Rooftop and Small Solar Plants Programme of the Ministry. This is available on First come First Serve basis and with a limited budget.

Net metering in rooftop solar projects enables the self-consumption of electricity generated on-site, with the surplus energy being fed back into the distribution network. Under net metering, the beneficiary pays the utility based on the net meter reading, considering the difference between the electricity consumed from the grid and the excess electricity exported.

Alternatively, a setup with two meters can be implemented to measure power export and import separately. This dual-meter configuration provides a more detailed account of the energy flows in and out of the system. Additionally, a mechanism based on gross metering, involving a mutually agreed tariff, can also be adopted as an alternative approach to determine compensation for the generated solar power.

A 1 kW solar power system is estimated to generate approximately 1300 units of electricity annually. However, this figure may vary based on the specific geographic location and local environmental factors that can influence solar irradiance.
