Hyderabad:To minimise electricity bills and fuel consumption, solar panels are said to be the best option to reduce pollution in the city. Installing home solar panels can dramatically decrease the electricity bills and tackle power cuts in summer as well, experts say.
“Earlier, solar panels were fixed mostly in large empty areas or a few on the rooftop. The situation has changed now, with the percentage of rooftop solar panels increasing over the last few years,” says A Sudhakar Rao, Managing Director and Vice Chairman, Telangana State Renewable Energy Development Corporation Limited (TSREDCL).
To ensure more use of solar panels in residential areas, the State government is offering solar panels in two categories, i.e. on the grid and off-grid. In the on-grid scheme, the excess power is supplied to the power grid whereas in the off-grid scheme, the power is stored in the form of batteries, the lifetime of which are five years.
“To set up solar panels as of now, the benchmark cost for 1 to 10-kilowatt is Rs 68 per watt; from 10 to 100 KW it is Rs 64 per watt; and above 100 KW, it is Rs 59 per watt. The State government is providing a subsidy of 30 per cent on the benchmark or on invoice price”, Rao said.
The cost of a 1KW solar power unit is Rs 1, 45,000 and after 30 percent subsidy, it will be Rs 55,000. In a similar manner, for 1 KW solar power unit, the cost in the on-grid scheme is Rs 70,000 after subsidy, it will be Rs 49,000 in the urban areas, Rao added.
In residential rooftop solar panels, the excess power generated is sent to the grid and may be helpful in cutting down electricity bills. The exported current will be deducted from the bill and the new amount will be displayed on the customer bill and in case the export is more than the import, then the additional units of power will be transferred to the next month’s bill,” TSREDCL General Manager Satya Vara Prasad said.
To avail solar panels for the residential purposes, the consumers can approach developers for supply, installation and commission of 1KWp to 1000KWp grid-connected rooftop solar PV. “In the State, there are 51 developers and by paying the prescribed fee to the suppliers, one can easily install the solar rooftops at residential places,” Prasad added.
