Our New Solar Panels!

A time of crazy travel, just how it worked out. Back from a delightful week in Puerto Vallarta with my sister and her dear friend and colleague from Poland – his first visit to Mexico, and great fun was had eating and lying in the sun and swimming with dolphins and trying different kinds of margaritas. Many people believe that Puerto Vallarta is uninhabitable in the summer because of the heat and humidity, so there were very few people at the resort, and that made it even nicer. Yes, it was hot, but we were never more than a few steps from the pool or the beach, so we didn’t care!

We came home for just a few days, then we head out again for New Jersey and New York for my Aunt Kay’s 90th birthday party, a couple of performances in New York (Netrebko in MacBeth, one could not resist, and Audra MacDonald’s Billie Holiday show) and restocking some supplies to get ready for the harsh Mexican winter. The most urgent thing – since we don’t have any heat in our house – is a new electric blanket since ours died and the controls and cables were somehow lost in the move to the new house. It doesn’t get terribly cold here, maybe down into the forties or even the high thirties in the middle of the night during the coldest part of January – but without any heat in the house you do feel it. Electricity is expensive, though, and it’s controlled by the Mexican federal government – they can basically charge whatever they like – so running that nice warm electric blanket or the space heater in your bedroom becomes quite a luxury.

Thus it is hard to live in Mexico, where it is sunny pretty much all the time, and not have the thought at least cross your mind that if you could harness all the energy the blazing sun just gives us, especially in the winters when you use more electricity in the shorter and colder days (ironically, it is sunnier in the winter months) you could realize a huge savings in utility bills over time. We have never had enough hot water, and even with our old hot water heater cranked up to “max”, the water, especially at the far ends of the house, was never really hot enough. Friends and our architect all commented that with solar hot water we would have water that was so hot we might well have to install a gizmo that mixes some cold into it so we wouldn’t burn ourselves, and we both became intrigued with the idea. Indeed several friends who have done this have told us that they are delighted with the result; both because your electrical bills go down to virtually nothing and that you really can generate enough heat to have plenty of hot water without needing to be continually purchasing propane. And we have been consuming a LOT.

After a year of lukewarm showers and not-quite-clean dishes from the dishwasher, I was ready to give the whole solar idea a try.  So, in a mad impulse we decided to have solar panels installed on our roof to generate electricity and added a solar hot water heater as well. The solar hot water tank should reduce our consumption of propane very dramatically. Poor Francisco the propane guy will be very sad when he stops by next time to fill our propane tank and we won’t be needing any — hopefully, not for months to come. Not only will it be fun to use all the electricity I bloody well want (keep the fountain running, which keeps it from getting full of algae, have the pool heater on more frequently, all those little things where you are conscious of turning switches off all the time….) since we are generating our own power now, but we can feel smug about doing the right thing to get off the grid and reduce our consumption of fossil fuels. While it is a big investment upfront, one can calculate that after a few years the investment will have repaid itself in reduced utility bills and from that point forward, most of your electricity and hot water (except for the few cloudy periods we have here) are basically free.

So we now have a big array of sixteen solar panels, plus the solar hot water heater, up on our roof, and it will definitely get in the way of my planned New York-style roof garden, but there is still plenty of open space up there so whenever I do get around to dragging some flowerpots and plants up there, it’ll still look nice. The solar guys still have some tweaking and adjusting and cleanup to do, but it is kind of amazing to see how it works. After some preparatory laying of cable and making new connections to our electrical boxes, a very efficient team of maybe ten young guys from the solar energy company climbed up to our roof and in one day they had the whole system installed. After it was done, they told me to come out to the street and stand in front of the electrical meter to watch what was going to happen as they flipped the switch and turned the new solar system on. “Watch; your meter will begin running backwards, Señora”, they said. “At that point you will be generating power and sending it BACK to CFE (the federal electricity commission). Sure enough, all of us crowded eagerly around the meter stuck in our cement front wall and the second they turned the system on, the little wheel inside the meter obediently reversed direction just as they said it would. I can hardly wait, now, to get our next electrical bill!
