How to utilize Solar Energy

Electricity users in India are typically classified into 3 different categories as Commercial, Industrial and Domestic consumers. Solar Industry offers solar news, as well as comprehensive coverage of the technology, tools and trends that drive the solar energy sector.
Solar’s growing share of the energy mix is being driven by better storage capacity and attractive generation costs. Large solar parks are now competitive with most alternatives; their average cost is below 5 cents per kilowatt-hour in some countries. The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity throughout the day. This device converts the DC electricity generated by the solar panels into the alternating current (AC) electricity.

Solar offers key advantages:
facilities can be built quickly, do not need fuel to be transported to power plants, and can eliminate transmission costs where mini-grids or off-grid units are built to serve local communities.
A significant 44.2% of the entire electricity generated in India is used for industrial consumption, making it one of the most important sectors with respect to electricity demand. The grid tariff for industrial consumers can go as high as INR 7/unit for non-peak hours and is much more for peak usage. Pertaining to heavy usage, especially during the peak hours, electricity constitutes major variable cost for industries. Industrial solar power, therefore, is a way to reduce the peak loading of the grid and do away with high tariff rates for the peak hours
. The high load requirement and large available rooftop area compared to commercial and domestic consumers make solar a viable alternative for industries. Often, the other incentive for many big industries to use ‘industrial solar power’ is to show increased share of renewables in their energy portfolio and meet their RPOs (Renewable Purchase Obligations). Industrial firms with captive ‘industrial solar power systems also have the option of availing tax benefits, capital subsidies and other incentives as applicable.
Solar power for industry can either be generated from an in-house solar plant (captive model) or through an off-site solar farm. The solar power thus produced can be used for normal day-to-day operations of the plant including lighting, ventilation, and equipment power supply. There are certain industrial firms in India which are meeting close to 30% of their power requirements through solar energy. The solar power system used by industries can be equipped with a battery storage system also. The battery storage makes the solar plant even more relevant when it comes to reducing the electricity cost.
The in-house PV plant can be owned and operated by the industrial firm (CAPEX Model) which owns and operates the plant and sells solar power produced back to the firm (OPEX Model). It is feasible for big industries with very high load requirements to get installed captive solar power plants within their facilities. Solar developers in countries are building solar parks in different states for catering to requirements from a group of small industries operating in the nearby area. Providing solar power for industries has hence become one of the highest growing segments for solar firms in countries.

Partnerships and investments in the solar sector have been at an all-time high lately. The bank also plans to work with other multilateral development banks and financial institutions to develop financing instruments to support future solar energy development in the country. The Government of India and the Government of the have signed an agreement to work in collaboration in the fields of solar energy. This partnership is expected to yield high quality and high impact research outputs that have industrial relevance, and are targeted towards addressing local needs. With the increasing share of renewable energy, the Government of India has decided to operate on a separate power trading platform. The proposed platform would help states buy, sell and trade renewable-based power.

Solar Plant have mainly two types:
1) On Grid: The on-grid or grid-connected solar is a solar electricity system without batteries. Your home is hooked to both the state grid AND your solar electricity system. This will ensure that you always have electricity irrespective of whether it’s the day or night, sunny or cloudy. This is what most people opt for in their homes because the on-grid system warrants that if your solar system over or under-produces, your local utility’s grid will cover for you.
What this means is that your utility system acts as your battery. If your over-produce, you can receive bonus payments if you export the excess energy back to the grid. On the other hand, if your under-produce, you’ll still get the required power because you’re connected to a grid. For areas with stable power situation (less than 3 hours of power cut daily) – this is the way to go.

2) Off-Grid: Off-grid solar systems allow you to self-sustain your energy use entirely. Off-grid connected solar is a solar electricity system with battery backup. The battery gets charged from the sunrays and supplies power to you. When the sun is absent, you use the power you’ve stored in batteries. In this system, the batteries can also be charged with grid power, if needed.
Being off-grid requires you to pay for panels, inverters, and batteries up front. Although the price of these items has reduced considerably, batteries still are expensive and also require maintenance.
