    If you are a resident of UP, your bill will show total surplus solar energy exported to the grid, total power taken from the grid and balance surplus solar power from previous month (if any).

    If you are a resident of UP, your bill will show total surplus solar energy exported to the grid, total power taken from the grid and balance surplus solar power from previous month (if any). In UP, the calculations of net energy charges are done based on the solar power an grid power usage. However, even if your surplus solar power is more than your consumed grid power and the energy charges are in negative, you have to pay for your fixd monthy electricity meter charges and electricity duty.

    The delay could be primarily at two end-one at the solar vendor end and other at the discom-level end. As per consumers’ feedback, sometimes solar vendors delay the installation of the project due to lack of manpower or availability of raw materials while several times discoms delay the process in inspection of the rooftop system post installation, installation of net-meters, testing of meters and final commissioning of the project. However, several state electricity regulators are now issuing directives to streamline the process.

What is the relation between TOPCOn modules and watt-peak (Wp)?

    TOCOn based solar modules come in high Wp. Like above 620 Wp. That means that the similar single panel can produce more energy that the conventional soalr panels. This will allow lesser requirement of land for solar projects.

    The most common metric we see in use is typically $/watt or Rs/watt in India. As it says, what that means is you consider the module cost, and divide it by its nameplate capacity to arrive at a number. Thus, a 500 Watt module priced at say, Rs 8000 per module will give you a RS/W cost of Rs 16 per WRead more

    The most common metric we see in use is typically $/watt or Rs/watt in India. As it says, what that means is you consider the module cost, and divide it by its nameplate capacity to arrive at a number. Thus, a 500 Watt module priced at say, Rs 8000 per module will give you a RS/W cost of Rs 16 per Watt. While this measure works for smaller projects, you might want to consider many other factors for larger projects.

    These range from the technology you prefer (Mono PERC or TOCon or even HJT) , to rate of degradation, thermal performance etc. With larger modules in recent years, we have also seen that these are faster and easier to install, although there is an enhanced risk of breakage as well during setup.  Similarly, how these are aligned to other key suppliers like trackers (in case you have opted for them) to even the inverters matters. So make sure to consider all these factors carefully.

    Remember, cost per Watt should be your starting point, no more. Look for credible, third party validated indicators for all other key parameters, before deciding finally.

    Encapsuilants are sheets that are used as a surface between the solar cells and the glass to give adhesion and protection.

    The additional surplus solar energy produced in rooftop solar setups in a grid-connected rooftop solar system is given to your electricity distribution company. The total number of surplus units not used by you and sent to the grid is also adjusted in your bill. So for example 100 units of surplus solar energy is not used by you and was sent to the grid, the electricity company while generating your bill will reduce 100 units from your total energy that used from the grid.

    Solar cell manufacturing is inherently more complex than solar module production, which is largely an assembly-based process. The production of solar cells requires significantly higher capital investment at the outset. In India, the establishment of solar cell production facilities also involves navigating additional regulatory hurdles. This is due to the water usage during production and the disposal of effluents. Furthermore, the handling of ingots and wafers involves working with hazardous materials. As a result, apart from the capital requirements, solar cell manufacturing and related backward integration must comply with stricter environmental, pollution control, safety, and waste management regulations at the state level.

    No. There is no free solar scheme run by the government. These are rumours created by fake website. The Ministry of New and Renewable Energy (MNRE) is actually running a subsidized rooftop solar scheme for residential consumers where the consumers can get upto Rs 78,000 subsidies for installting rooftop solar. However, they have to bear the upfront cost on their own at the time of installation. There are other subsidized solar schemes too like PM-KUSUM where farmers get solar pumps with subsidy support.
