Anyone know about investing in solar panel farms in Japan? Supposedly the return on investment isn't too bad.
This is one of the only sites I could find in English - www.tsp-cg[dot]com/english/solarenergy
Let's say you purchase a small plot of rural land in sunny Aichi Prefecture for 1,000,000 yen. You then install a 6.05kW Panasonic solar system for 1,654,000 yen (inclusive of all installation costs). You have now invested a total of 2,654,000 yen into your 20 year solar farm project.
According to this industry web site, which breaks down the yearly cash flow in great detail, you would recoup the cost of the panels at year 13. By year 20, your total income would be 383,000 yen after deducting maintenance costs of 300,000 yen. However, this is misleading since you need to pay property tax on the land as well. At 1.1% that would be 220,000 yen over 20 years, leaving you with a net profit of 163,000 yen.
We can assume this is a highly unrealistic scenario under pristine climatic conditions and stable, non-depreciating land and solar asset values. In reality, the solar panels will depreciate by about 90% over the 20 years leaving you with 1,000,000 + (0.1 x 1,654,000) + 163,000 = 1,328,400 on your initial investment of 2,654,000 yen for a net loss of 1,325,600 yen.
Now imagine that you had invested the same amount of money in an S&P500 index fund in your tax advantaged retirement account over the same period. After adjusting for inflation, the S&P500 has averaged an annual rate of return of 5.9% over the past 20 years. Applying that to our initial investment of 2,654,000 yen and letting it grow untouched in the retirement account would leave us with 8,352,569 yen after 20 years.
That's just a quick back of the envelope estimate. Feel free to correct me if I'm wrong!
