Theemergence of renewable technologies is a boon for the future of our planet.
Though, the damage done by burning of fossil fuels can’t be reversed, it ishowever possible, to alter and reduce further impact of green house gases onour environment by adopting green technologies. Several experts cite, thathumanity has breached the point of return on climate change. However there ishope that by curtailing our dependence on fossils we can ensure a liveablefuture for the coming generations. One such method is Solar energy.Solarenergy is an increasingly important part of our nation’s current energy mix andwill play a vital role in our clean energy future. Today there are a number ofways through which we can obtain solar energy, including the large-scale utilityprojects, residential rooftop solar panels, and policies designed to utilizemore green power.
Large-scale utility solar projects amount to approximately 60percent of the country’s total installed solar capacity—and this capacity isexpected to triple by the end of 2020. These projects offer the mostcost-effective way to increase the use of solar that benefits all electricitycustomers. Just as the number of utilitysolar project grows, there is also growing interest in using rooftop solarpanels and other small-scale, on-site power sources known as distributedgeneration (DG). To encourage the introduction of these systems, many stateshave approved a billing system called netmetering. While net metering policies vary by state, customers with rooftopsolar or other DG systems usually are credited at the full retail electric ratefor any excess electricity they generate and sell to their local electricutility via the electric grid.
Net Metering is a billing mechanismfor grid connected Home Rooftop Solar Installation where The electricity generated by the solar panels is fed into the utility grid. Household draws electricity from the utility grid.Thehousehold pays only for the difference between the energy units it consumesfrom the grid and the energy units fed into the grid.
Hence, it is a bi-directionalmeter. In the case of household generating net excess power during a month or aparticular billing period, it earns credit for the excess electricity fed tothe grid. This credit is carried forward to the next billing period when thecredit is deducted from the total power bill of the consumer. This reducespower bill of the household significantly as it only has to pay for the net electricityit consumes from the utility grid.Throughthe credit or payment they receive, net-metered users effectively avoid payingthese costs for the grid.
NetMetering helps households using Solar Rooftop Installation get reliable powerfrom Solar energy which fluctuates from day to night and summer to winter. Butit also brings a basket of other benefits to households using them and thesociety. Reducing OurBills:Ourelectric bills are based on the electric utility’s cost of providing electricservice. This includes the cost of the fuels used to generate electricity andthe cost to transport and deliver the electricity to the customer. Costs alsoinclude the maintenance of the grid, as well as utility programs for low-incomeassistance, energy efficiency, environmental improvements, and other publicbenefits. In general, every electric consumer has an electric meter thatrecords the amount of power delivered by their electric utility. As electricityis used, the meter spins forward, much like a car’s odometer records milestravelled.
In the case of an electric meter, the meter records energy use inkilowatt-hours (kWh). Net-metered users generally are credited for the electricitythey sell to the grid, with their electric meter essentially spinning backwardsto provide a credit against the electricity that these customers must buy fromtheir electric utility at night or during other periods when their electricityuse exceeds their system’s output. Consumers are only billed for their “net”energy use, which means that when rooftop solar or other DG users generateelectricity, they avoid paying for the utility’s power, which is fair becausethey did not use it. But, they also avoid paying for all of the fixed costs ofthe grid that delivers power when they need it and/or takes the excess powerthey sell back to the utility. Withnet metered Solar Rooftop Installation, we only pay for the deficit powerconsumed i.
e. the difference between the power consumed by our household fromthe grid and the solar power generated from the panels. This drasticallyreduces electricity bill and we save ahuge chunk of our hard-earned money.
Low Maintenance : With net metering, we have now eliminated thebatteries and the backup generator – the two components of a solar power systemthat require maintenance and have the shortest lifetimes. The onlycomponents we need for a grid-tied net metering system is the solar panels,which produces the power, and an inverter that converts the DC power from thesolar panels to the standard AC power produced by the utility. Neither ofthese components requires maintenance.
The solar panels, which have a fewyear warranty, are made from a semiconductor material and usually protected bya tempered glass front. The inverters, some of which also have 25 yearwarranties, are solid state and also maintenance free. Thus, it saves our time as well asmoney.Better Energy Utilisation :Powergenerated from utilities travel quite a distance to reach our home.
That incurssignificant transmission and distribution losses and wastage of electricitygenerated from burning fossil fuels. T losses in Solar RooftopInstallation are almost nil as energy is generated and consumed at the samelocation. This not only reduces energy congestion and make overall energyinfrastructure more efficient but also benefit residents with improved gridvoltage.Need LessResources :SinceNet Metered Home Rooftop Solar Installation is installed on the roofs ofresidential houses and commercial buildings, they do not require large tractsof land like their solar park cousins.
Land is scarce and increasinglyexpensive. With net metered residential rooftop solar plants, these resources aresaved for other productive purposes like agriculture.Indiabeing a fast-developing country whichreceives about 300 clear and sunny days in 365 days has quadrupled its solar-energy generation capacity in past fewyears. The solar energy available in a single year exceeds the possible energyoutput of all of the fossil fuel energy reserves. Thus, net metering is crucialfor our country in order to achieve energy security by 2022.
In the comingfuture, solar rooftops will be an advisory by the government. Many stategovernments are also providing subsidy on solar solutions which is a moralboost for a consumer relying on net-metering to save money on the electricitybills. Net- metering can help India achieve energy security through generationat point of consumption (distributed generation).
Besides helping consumers toreduce their burgeoning electricity bills, it can play an instrumental role instabilising national, regional and state grids. It can also help discoms tideover their financial losses through consumer default risk mitigation. It alsohas the potential to minimise AT and C losses and reduce per capita energyfootprint. “So, net-metering system has a huge horizon in the upcoming era ofrenewable energy.
