March was the best March in 11 years for my photovoltaic generating system. Last month, March 2018, my solar panels generated 108.55 percent of the electricity I used.
The current billing period beginning on March 2, has been extremely productive. As you can see in the chart from my utility, the gray bars that dip below the 0 axis are the days my solar panels generated more than I used in my home. The statistics for the period are revealing. The overall average […]
My electricity bill for the last 12 months is $540.70. That averages out to $45.07 a month. If I assume that my monthly bill used to average around $250 a month, that is an annual savings of $2,459.30 a year. My solar panels have been operational for 11 years. That means I have saved a […]
Here’s an update on the performance of my solar panels this year. My new mini-split A/C is paying dividends by allowing me to cool my bedroom at night to a comfortable level while keeping the rest of the house at a higher temperature. The days are getting longer and I am optimistic about the next […]
People often ask how my solar panels affect my electric bills. My total cost of electricity for 2017 was $521.37. Here’s a chart from my utility that illustrates my monthly electric utility bills. Note that my average monthly bill is $45. If one assumes that the average monthly bill for a south Florida home is […]
I’ve been running my house using my new air conditioning procedure. I turn off the central air for most of the day. I run the Mitsubishi, high efficiency, mini-split in my bedroom at night. In the morning I run the central air for about half an hour to take the humidity out of the house. […]
My new SEER30+ mini-split air conditioner has been operational for a few days now. I’ve been running it at night with my central air conditioner off. It’s difficult to say how much impact that has had in increased efficiency, but there is no doubt it has to have contributed greatly. Other factors to be considered […]
Ten years ago, when we conceptualized our photovoltaic system as an emergency power source when the grid was not available. The plan included a mini-split air conditioner for the master bedroom. The idea was that during an extended grid outage, such as occurs after a hurricane, we would be able to power our house and […]
Milder daytime temperatures since the hurricane have reduced consumption from air conditioning, along with a lot of cloudless days have resulted in higher percentages of energy being produced from my solar panels. The chart on the right shows that over the last ten days, percentages generated from solar have been near seventy percent on average.
