Solar Panel Project Update - Part 3
In my previous post I explained how I improved the accuracy of my DC sensors using ADS1115. But there is one problem though. The ADS1115 gives accurate reading even when the supply voltage keeps changing. Yet, the sensor values will not be correct. The reason is that if the supply voltage is changing, the reading on the sensor will also change, but the accuracy of the reading will be stable because ADS1115 is independent of power supply voltage fluctuations. For example, let’s say the supply voltage is 2.5V, then when there is no current, the DC current sensor will read 2.5V, and in the code we assume the current is 0 at 2.5V. Now if the supply voltage drops to 4V then the sensor will read 2V, which is still the mid point and indicates 0 current. But in the code we have a hard coded number that 2.5V is the midpoint and we mistakenly assume that some current proportional to -0.5V is passing through the wires. That is the problem.

Tax Loss Harvesting
There are lots of legitimate ways to reduce taxes and tax loss harvesting is one of them. However, in practice, it is much harder to execute. But before we get ahead of ourselves, let me explain what tax loss harvesting is in case you don’t know. Tax loss harvesting is nothing but selling your investments for a loss when the value is below your invested amount. Then use the losses to offset any other capital gains or income that you might have. Generally tax loss harvesting works well with equity markets because there is a possibility that the markets fall and your investments could be worth less than what you invested.

Solar Panel Project Update - Part 2
This is a continuation of my previous post giving updates about my solar panel setup. As you will probably remember from that post, I found a good sensor that would measure AC voltage and current accurately and I was satisfied and very confident about the data coming from the sensors. However, I cannot say the same about my DC measurements. Many components in the system should be measured in DC including solar panel current, battery voltage and current etc. My initial set of sensors were not accurate and used to drift quite a bit with supply voltage and ambient temperature. So I set out to find better sensors and upgraded them and I cover part of that story in this post.

Reducing My Asset Allocation Swings
Ever since I started investing back in 2011, I have always wanted to do tactical asset allocation. The idea was not to maximize returns, but to minimize volatility. Tactical asset allocation is different from the general advice which you receive from many people including me which is to keep a fixed asset allocation and rebalance once in a while to make sure that the asset allocation difference remains within a small range. That advice applies for any long term goal like retirement. For shorter goals you may receive advice to reduce equity allocation as you near the goal. If I did not make any sense there, then let me explain with an example.

Solar Panel Project Update - Part 1
It has been a while since I gave any updates on my solar panel project so I thought I should write a post on it. This can get pretty technical so if you are not into electronics or software, you can skip. Since I last reported about my design I’ve made a few changes mainly to increase the stability of the system. What happened was that in the long run, I found some problems that rear their head sometimes intermittently. As a result I had to change the design to recover some components from their weird state. In addition I reduced the variability of readings by the sensors.

Year In Review – 2022 Net Worth
The last post in the year in review series for the year is on my net worth. I am doing the net worth calculations using the very basic formula for net-worth which is basically
...continue readingassets - liabilities. Some don’t agree with that formula, but I will continue to use it since that is what I have used in the past. If I change the formula now, then there will be discontinuity in the numbers. Moreover, since I don’t publish any numbers, it does not matter what my net worth really is. It is only to show how it has grown or fallen over the years. My retirement is in no way dependent on my net worth. It is only dependent on my corpus of investments (debt MFs and equity MFs). -
Budget 2023 And How It Affects Me
Every year after the union budget I publish a post on how it affects me. I am doing the same again now. Usually the budget does not affect my financial planning much except for that one time when the finance minister introduced the tax on long term capital gains on equities. This budget was pretty mild and simple. No nasty surprises (at least for me). The only announcements that needed any financial planing were –

Five Years In Financial Independence
It has been more than five years since we became financially independent. It was end of 2017 when we concluded that we have enough investments to call it a day and hang our boots. It felt like life would be awesome and we can enjoy living a slow life. Which is exactly we did for the past five years and we have absolutely zero regrets regarding early retirement. We are living the life at the slowest pace we have ever done. There is barely any urgency in any matter of our life. No wonder so many people ask – what do you do with all the free time?

Year In Review - 2022 Returns
Continuing on in the year in review series, I now take a look at my returns in 2022. Although this is not really important since investments are for long term and there is no point looking at returns every year, I like to review it nonetheless. Last year, the stock market contrary to its general nature, did nothing interesting really. It was mostly flat with the market touching the peak around January and went down to the lows in June and back up by December. In the end, most of the indices that I track have ended slightly higher than where they started the year. My corpus performed inline with the indices, nothing too high or low. Enough talking lets start by comparing my portfolio returns with some of those indices.

Year In Review - 2022 Annual Expenses
In the previous post I wrote about my monthly expenses. This is the continuation of that post and I will be covering my annual expenses in 2022. While monthly expenses are those kind of expenses that occur more frequently, yearly expenses occur rarely, perhaps once every few years like house repairs or buying a new car etc. I will explain where we are spending the most and why. Remember that for all the expenses, whether monthly or annual, the money is coming out of my retirement corpus which consists of a bunch of debt and equity mutual funds. There are no other incomes or special savings for annual expenses. Every year since retirement we have seen different kinds of expenses and last year wasn’t any different either.
