Progressing to sustainable power source is a compelling method to decrease your power cost and carbon impression. A sunlight based housetop plant is one of the simplest and most savvy approaches to meet your vitality prerequisites. Ordinarily, a sun oriented housetop plant of 1-kilowatt crest (kWp) limit requires 10 square meters or 100 square feet in territory, aside from a one-time venture of Rs.50,000– 60,000. With a life expectancy of 25 years, a 1 kWp framework creates around 120 units of power a month and around 1,300– 1,500 units per year, contingent upon its area.

The different favorable circumstances of progressing to this spotless vitality framework should speak to our natural cognizance and monetary sensibilities. Give us a chance to take a gander at a portion of these preferences:

Decreased power costs: A normal family devours around 3,600 units of power a year while a sunlight based housetop plant of 2 kWp limit creates 2,600– 3,000 units every year. This adequately implies most families' power utilization would be free of expense in the wake of introducing a sun powered housetop plant and associating it to the network through net metering.

Under the net metering component, the power created by the plant is utilized for family unit utilization and any abundance control is sustained back to the matrix. On the off chance that the measure of intensity created isn't adequate, loads are served by illustration control from the network. At the point when your sun based housetop plant creates more power than is being expended, the power meter records the units encouraged into the network. On the off chance that the power utilization surpasses age, the meter records that too. Toward the month's end, you need to pay just for the net power expended. Be that as it may, if more power is produced than devoured, the additional units of power are credited to the following month's bill for settlement. Toward the year's end, the power utility pays you for any abundance age. This framework guarantees that you are charged just for the net power devoured (utilization less age).

Furthermore, you spare in the higher levy piece. For example, the initial 100 units of power utilization in Delhi are charged at Rs. 2 for each unit while the following 100 are charged at Rs. 4 for each unit. In the event that the power utilization is between 200– 400 units, you are charged around Rs. 6 for every unit, and around Rs. 7.30 per unit if your utilization is somewhere in the range of 400 and 800 units. As your net utilization runs down with sun powered housetop and net metering, you will pay for power according to the lower levy chunk. Taking into account that power levy increments 5– 6 percent consistently, your investment funds will viably increment after some time.

Gratefulness in esteem and diminished carbon impression: A sun based housetop framework is among the couple of ventures that acknowledge with time as there is a consistent increment in investment funds, as referenced previously. It is likewise a simple and savvy approach to do your bit for the earth. With the utilization of each unit of warm power, we produce 0.7 kg of carbon dioxide. Along these lines, each unit of sun based vitality forestalls 0.7 kg of carbon dioxide discharge. Introducing a 1 kWp sunlight based housetop plant is along these lines proportional to planting two trees as far as carbon sequestration.

Compensation period: Depending on your state's levy, the restitution time frame for a sun powered housetop framework introduced with a speculation of Rs.1 lakh differs from 5– 7 years. For example, Delhi has a high duty structure where power is charged at Rs. 8.95 per unit in the most noteworthy utilization piece. Amid summers, a two-BHK house expends over 800– 900 units of power. A sun powered housetop framework creates the most elevated measure of power in summers, and mitigates the lofty bill, prompting reserve funds of Rs. 8.95 per unit for this situation.

Zero activity and upkeep cost: Consumers don't bring about any support and operational expenses on a sun based housetop framework as it doesn't have any moving parts. The main upkeep required is cleaning of the sun based boards to guarantee most extreme retention of daylight. This is a simple procedure that should be possible once per week or each 15 days, contingent upon the residue conditions in the territory.

No space crunch or sound contamination: A sun oriented housetop plant does not make any clamor amid tasks and the rooftop space it takes up can likewise be diminished by building a lifted structure to help the boards. This structure likewise gives a shaded rooftop and its related points of interest of decreased temperature in summers.
