What are the Solar Options for Residents of India?
– by Sandeep Chandra
Let us take example of Delhi. On 8th September 2014, Delhi’s Electricity Regulator Commission, DERC – notified its Net-Metering Policy for the benefit of residents of Delhi. This Policy also applies to all businesses, schools, factories, hospitals, hotels, etc operating within Delhi. So, now Delhi residents can have own Solar Power System, help the environment and save money too!
Most other States are either ahead of Delhi (Kerala, Gujarat, Tamil Nadu) or following up (Rajasthan, Punjab, Assam) with similar Solar policies
DERC released guidelines for all supply & distribution companies that serve Delhi – NDPL, BSES (Yamuna) and BSES (Rajdhani) – to enable Delhi residents and businesses to connect their Solar Power systems with these companies’ respective electricity grids
What does this mean to you? Under this policy any buyer of power in Delhi can install their own Solar Power system, connect it to the local grid and earn savings on power bills from electricity produced. Not only that, if there is a net surplus over the billing period, your bill for that period will be zero plus you will accumulate a credit for the extra power you feed into the grid! How cool? This is possible due to NET-METERING
How do you take advantage of this? It depends on your current situation. Do you live in a single house or in a society? Do you have spare space on your rooftop? Do you currently use a genset or an inverter/UPS? Do you want solar power to supply you when grid supply goes off? Are you a user with large reactive loads, eg a lot of motors, air-conditioners, etc? Are you a heavy user during peak hour and paying peak rate? In most situations your best option will be solar panels on the roof with an inverter (called grid-tie inverter) feeding the grid
Some of the options are:
OPTION 1 – Setup your rooftop solar power system, connect with the grid and net-metering takes care of the power produced and power used equation so you get an adjusted bill each month. In this option, if grid supply goes off, so does your supply. You do not get power automatically because you have a solar power system. Surprised? Yes that’s true
OPTION 2 – Similar to Option 1 but rather than selling surplus to the grid, you store it in batteries, so that if you lose grid power, batteries can support your load. Size of batteries will greatly drive your cost in this option
OPTION 3 – Enhance Option 2 with a genset, so that you always get power, whether from solar or batteries or genset depending upon time of day, type of load, etc. This option helps to contain your total solution cost and you may be able to keep your genset as well, if you have one!
Deciding the best option that minimizes your monthly power bills and keeps total cost of your solar power system as low as possible is absolutely critical
If you ever thought of Solar or wanted to go trendy about the environment, then a wonderful opportunity now welcomes you
