7 things You should know  About Solar Rooftop Systems

Over the past few years, India’s renewable energy generation capacity has increased rapidly. India has set a target of reaching 175 GW of green energy capacity by 2022. In the sector of Solar energy, India has increased its capacity by eight times during the financial years of 2014-2018. The Government of Gujarat is planning to take the current solar capacity that is 28 percent of total capacity to 53 percent.

Since the early days, the Gujarat Government has been showing a keen interest in solar energy, by being one of the first states in India to implement the Solar Energy Policy. As having reasonable advantages, solar rooftops have gained popularity in Gujarat as well. These solar rooftops can be installed on residential as well as commercial buildings. 

All this information seems to be very interesting and it might interest you to install the solar rooftops on your residential or commercial building. And you must be eager now to know more about the solar rooftops so let’s see some more things which you should know about the solar rooftop.

  1. Types of solar rooftops  

Stand-alone solar rooftops: These kind of rooftops are not dependent on the grid, they function with diesel generator or batteries.

Grid-tied solar rooftops: These rooftops work with grid only. It means PV combines with the grid.

Hybrid rooftops: This type has benefits of both Standalone and Grid-tied.

  1. Raw materials used in Solar panels

    The raw materials used to make solar panels are; silicon, sand, ingots and silicon cells. Silicon cells are attached together that forms a structure that is called solar panels.  

  2. Solar rooftops are eco-friendly

    While generating energy, the solar panels of the rooftop do not release any kind of harmful greenhouse gases.

  3. Cost of rooftop solar system

    The cost of a solar rooftop system completely depends on the size, type, location and the quality of the product. The cost of 1KWP solar rooftop PV project could be ₹ 48,000 approximately and that is including installation. However, this cost is excluding the cost of storage batteries.

  4. Subsidy offered by the Government

    The Central Government offers a Capital subsidy at the rate of up to 30% of maximum Benchmark cost. The Government of Gujarat offers a subsidy of ₹10,000 per kW of installed capacity up to a maximum of ₹20,000 per customer.

  5. Net metering

    It is a billing mechanism that offers credit to solar rooftop users who are generating excess electricity at their residences or businesses. So when the building is net-metered, the user will only pay for the “net” energy used every month. And this “net” energy is the difference between the generated electricity and the consumed electricity over the period of one billing cycle.

  6. Solar Rooftop Calculator

    MNRE(Ministry of New and Renewable Energy) department offers a Solar rooftop calculator for the grid-connected rooftop systems.

Now, as you know that the solar rooftops are really amazing both economically and environmentally, you must be looking for the company that offers the best quality and cost effective solar rooftops. Before going anywhere else, why not check here
