Balance Transfers – A Kiwi Microfinance Blog
Everything Micro Nothing Macro
It’s a bit early to do a case study on solar power for the Otaki Motel, because quite frankly, we haven’t received enough data yet to assess how much of an impact our 1.5 kWh solar power system has had on out energy use across all weather patterns and seasons. What we have had is our first electricity bill come in.

The motel solar power system has now been successfully installed. I’m able to log in to my inverter system (through Enphase Enlighten) and get a near-real-time reading of the energy consumption versus production through the solar panels. This reading quickly threw up an unintended side effect, which is that the motel solar system is producing way more power at present than the original estimate.

In last week’s article I made the on-the-surface ludicrous claim that the value of a solar power system at the end of ten years may be greater than the value of that same system at the date of purchase and installation, even when accounting for the loss in energy efficiency of said solar system over 10 years. Today I will explain how I reached that conclusion.
There are some assumptions that I need to make you aware of when using certain valuation methods, including the Discounted Cash Flow Method, to calculate the value of a solar power installation once ten years have already passed. Explaining and outlining these assumptions may go some way to support my on-the-surface outrageous conclusion that, for many households, the value of a solar power installation may be worth more ten years from now than it is on the date of purchase and installation, even when considering the loss in energy efficiency that occurs over time.
