Electricity Connection Application
After getting our bore drilled, we proceeded to get electricity connection. This was another messy process. To get a 3-phase connection so we can run our pump, we need to apply for electricity connection. Since there is no transformer near by, they cannot give us the connection directly. It seems unless there are at least 2 connection requests from a location, the electricity department will not setup a new transformer. The alternative is for us to bear all the costs of setting a new transformer and the cost of all the poles and wiring up to the transformer. The cost comes to around Rs. 2-3 lakhs.

How Much Money Did My Solar Panels Save? - 2023 Edition
A long time ago I wrote a post on how much money my solar panel was saving me. In the post I promised to write another post in November 2022 with updates. Well, lots of things happened and I completely forgot about it until one reader reminded me requesting for an update. So here it goes. It has been more than 2 years since I installed a 320W solar panel and I have been diligently collecting data from my panel, our consumption and how much we are pulling from the grid. Very recently I finally finished my code to fetch the data, massage it and used some nice libraries to draw the graphs so I can analyze the data.

Savings Due To Solar Panel
Last year, around this time, I wrote a post on how much money my solar panel was saving us. I was supposed to write a follow up to it after one year, but I completely forgot about it. Thankfully, a reader reminded me to give an update and here I am. Unfortunately even after one year I still did not finish the software that was supposed to instantly tell me how much I am saving each month. I should be able to get that information because I have a bunch of sensors monitoring my solar panel system. They measure the power generated by the panel, the amount of power we are using at home and how much power we are drawing from grid. All that data is stored in the cloud in Firebase. Yet I did not finish that part of the software. And to think I am actually retired. Wonder where all my free time goes. Anyway, in this post I will give a guesstimate using our electricity bills as a proxy.

How Much Money Did My Solar Panels Save?
It has been more than 6 month since I installed my lone 320W solar panel. So I wanted to check if it was doing me any favors and how much money is it saving. Normally one should wait for a full year to make any kind of useful analysis. But I get easily excited when it comes to doing any kind of data analysis and here I am at it again. It is a very small installation and hence the savings aren’t huge, but at least I am able to verify my predicted numbers (units of electricity) against the real numbers. Did I have any savings or was this whole solar panel project a waste of my time and money. Let’s find out.

Solar Panel Performance And Energy Savings
Alright, so I got my solar panels and solar management unit setup all done. Now for the results. According to the spec sheet of my solar panel, it should be able to generate peak output of 320 W. And it certainly did. In fact on some rare occasions it actually produced more than the rated capacity! I was really surprised that something can outperform a spec sheet. From the spec sheet, the panel is supposed to produce 320 W with an irradiance of 1000 W/m2 under standard test conditions (STC). Whatever that means.

Solar Panel Project - Do It Yourself
I was finally ready to install solar panels. After having made all the calculations, I arrived at the fact that I could get the return on investment in 5 years. But I had an even better idea. I decided do build it myself. What better way to learn about solar power except by doing it yourself! I always prefer to do things myself rather than letting some one else do the job for me. My work will be subpar at best, but it not only gives me a great opportunity to learn something new, but is also a lot of fun.

Solar Panel Project - Inception
I have been wanting to setup solar panels for several years now. It all started way back in August 2015 when for the first time the electricity bill touched Rs. 2,000. We don't even have air conditioner so what gives? At this point I started looking at the past bills and noticed the slow rise in unit rates. If you are interested, I already wrote a post on the inflation of electricity bill. That got me thinking if it is time for some solar panels.

Our Real Power Bill Inflation
In the last post I showed you that the electricity inflation over the last 9 was around 7% in Bangalore. Of course the inflation depends on how many units you use. If you are in the lower or higher slab than me then perhaps the inflation may be different for you.

Power Bill Inflation
I don't normally talk about my inflation numbers in this blog, because I don't have a lot of data. I am the kind of guy who needs data to talk about things. To make sense of inflation we need at least 7 years worth of data. Ten years data will be more useful though. Thankfully I have some of my electricity bills since 2012. So there is long enough history to see the inflation in electricity bills in Bangalore.
