Irma brought down energy infrastructure as she blew through state after state. The Carolinas lucked out compared to Florida. While Duke restored power to the tens of thousands of Carolinians without in a matter of days, Floridians who call the Keys home expected to be without power for weeks.
Of the millions without power in Florida after Irma, there were reports of one man who managed to keep the lights on. He was able to do so with the help of a solar array and a storage battery.
A combination of an array and battery creates a microgrid, a system consisting of generation and storage. With such a system, individuals use a utility company’s generation as backup when their system is not sufficient. Microgrids producing enough energy allows an individual to operate when a utilities company is down for the count.
Of course, if solar arrays are broken, ripped off a roof, or covered in snow, the microgrid no longer receives power. However, a backup plan to municipal utilities could always come in handy.
The Floridian was able to power part of his house, including air conditioning and his refrigerator. Whether looking for some extra security or preparing for the apocalypse, a microgrid rises to the occasion. With such a system, lives could even be saved as air conditioning or heat is kept on and perishable food is kept cold. Some of the crises we saw
Consider the possibilities of not being dependent on municipalities.
As solar installers, we’re often asked about the Tesla Solar Roof Tiles. Though aesthetically pleasing on a home, it is not affordable to the average homeowner. Today’s blog is by Spice Solar, our first guest blogger, where they addresses the pros and cons to the Tesla roof tile.

There’s no doubt in my mind that the home of the future will be solar powered. Intuitively it would be great if the roofing material provided that solar power. But historically it’s been a challenge to combine efficient solar cells with a durable roofing material at an affordable price. Tesla’s new solar roof tiles hope to solve these challenges.
Without a doubt Tesla’s solar tiles are the best looking solar roofing products I have seen. Using Tesla’s solar roof calculator and information for a 2,000 square foot home in California with a 2,500 square foot roof and $200 monthly electric bill, here is how their roofing tiles compare to an ordinary rooftop solar panel installation:
Of course I expect the cost for Tesla roof tile installations to come down in the future, so their economics are likely to improve. Nevertheless, at these high prices it is clear to me that Tesla really has a product that only makes sense for new construction on high end homes. For the average homeowner considering solar, by far the best choice is a traditional rooftop solar power system.
