Training kids to measure smart meters

This thought occurred to me on the way to work the other day, and might be one I develop a bit further in the future.

In previous articles I wrote about how it was essential to measure one’s own home energy use during day time before going so far as to install a solar power system. Without a comprehensive knowledge of the details of your household power consumption, you really can’t make any intelligent decisions regarding solar power, and in fact, many installations completed without paying close attention to home energy use will fall a long way short of expectations.

The problem is, not everybody has time to go and stand outside the front of their smart meter each hour and record data for several weeks before they decide to install. People have lives, believe it or not, and recording the kWh currently consumed by your household each hour on the hour is not high on their list of priorities.

So, who would be good candidates to collect this data? Not the parents in the household – the children in the household. In fact, one could make a fun family project out of it.

Need to keep the kids occupied during school holidays? Give them an exercise book and send them out to take readings off the smart meter.

Of course, it may need some clever packaging to make it happen – but if kids could be convinced to collect this data on behalf of parents, it would then lend credibility to many households when making decisions about their renewable energy generation.

Not to mention it would be a great way to teach your kids valuable skills in applied mathematics!

What is the ROI of a rice cooker (solar powered) with calculators

So my solar powered slow cooker diet is going well, with loads and loads of stress free and delicious food experiments under way, utilising great local organic Kapiti produce. I wanted to take a further step in the sustainability direction, so I bought myself a rice cooker to work along with the solar panels.

My Biggest Mistake With Solar Panels

Installing solar isn’t all plain sailing. In addition to the complexities of matching energy production to energy use, and the huge amount of math that goes into crunching whether you will or won’t break even, there are other obstacles. This article is about the biggest ‘trap for young players’ that I fell into when installing solar.

Excuse me, but why does anybody need solar power batteries?

Today I intend to lay out a system that works well in harnessing the power of the sun, without the need for any costly solar power batteries.

Geographical features that make Otaki Motel a good location for solar panels

Our solar power installation is now set up and in recent articles I’ve addressed how our solar installation is currently generating more than 50% more power than was initially forecasted based on NIWA data. The savings we’ve achieved have also been on the high side, cutting our bill down by around $93 during our first month and by around $150 during our second month. In fact, our monthly daytime consumption for last month, at 170 kWh, was the lowest number we have ever consumed during any month in recent memory.

Solar Panels on an Overcast Day vs Solar Panels on a Sunny Day

It’s a miserable, shitty, overcast day here in Otaki, and what better way to use it than to generate some fodder for my blog. And I had hoped to put my washing out today – oh well. At least one silver lining in this is I get to get some forward intel to help me plan ahead for the winter months, to see how our energy use will be affected.

My brother, the secret electricity hog

One of the unexpected side advantages of solar power is it gives you the opportunity to keep a careful watch on your whole family’s energy consumption. At least insofar as it makes their energy consumption habits a bit more conspicuous.

Ammeters: The First Step In Going Solar

For guys my age, solar power systems are the equivalent of a model train set. We know we’re too old for this shit, but we can kind of get away with it, because it helps the household save money and it’s also in the interests of the environment. Here’s why ammeters are a critical piece of the puzzle.

So Far, So Good – One Month In and Solar Is Outperforming Expectations

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.

Why Solar Power and Slow Cookers Go So Well Together

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.
