All these advantages come without leaving a hole in your pocket. Installation of the solar power system is a one-time investment.The investment reaps huge dividends in form of lower electricity bills for several years.
Installing solar panels significantly reduces monthly electricity bills and dependence on the power grid. According to long-term forecast solar remains a cost-effective solution and long-term investment in the future.
Sustainable carbon-free energy solutions such as solar are crucial in achieving our climate goals and the sustainable development agenda.
Solar Power means producing energy through photovoltaic process. The environmental impact of solar power is significantly smaller than other power generation method. No harmful emissions are released into the air when electricity is produced by solar panels This means your small measure can contribute significantly to save the environment.
Increasing usage of solar energy would lighten the load on the power grid and therefore ensure better grid security. This implies fewer power cuts and more protection from disasters.
The sun provides more than enough energy to meet the whole world’s energy needs. The photovoltaic process that transforms the eternal sunlight into electricity doesn’t require any fuel and has no variable costs. It produces electricity in an efficient and cost-effective way.
FAQs on Solar Rooftop System
In a solar rooftop system, the solar panels are installed on the roof of any residential, commercial, institutional and industrial building.
A 1 kw rooftop system generally requires 10 sq. metres (100 square feet) of flat, shadow-free area (preferably south-facing). Actual sizing, however, depends also on local factors of solar radiation and weather conditions and shape of the roof.
These are two types:
(i) Solar Rooftop System with storage facility using battery
(ii) Grid Connected Solar Rooftop System
The grid connected rooftop system can work on net metering basis wherein the beneficiary pays to the utility on net meter reading basis only. Alternatively two meters can also be installed to measure the export and import of power separately. The mechanism based on gross metering at mutually agreed tariff can also be adopted.
It depends on the consumption cycle. If the consumption cycle matches with the generation cycle then battery may not be required. Also, in case of net metering, excess power will be credited in the bill so no battery is required.
Subsidies are available from multiple channels for setting up Rooftop PV projects. Subsidy / Support from Central Government through MNRE. Government Institutions including Public Sector Undertaking (PSU) shall not be eligible for subsidy; instead they will be given achievement-linked incentives /awards. Subsidy / Support from State Government through State Nodal Agencies (SNAs) like UPPCL / UPNEDA in Uttar Pradesh: Subsidy support is also available in various states. The percentage of subsidy varies according to the state policies.
