I used to be an early adopter of the present era of photo voltaic know-how once I put panels on our San Jose home within the early 2000s, solely to observe the yield from these panels drop sharply over the next 20 years.
On our newest dwelling, we use current-generation LG panels which promise to carry over 90% of their producing capability for that very same time. However, not solely am I unable to get the Tesla batteries I ordered final yr (I’m informed I could have them by subsequent summer season), I do know I’m losing a ton of power as a result of my power use is unmonitored.
A really inexperienced dwelling is not only photo voltaic. It has a managed power system so you possibly can optimize use. But dwelling power administration methods that work properly with photo voltaic are exceedingly uncommon, and I’ve been upset in every one I’ve examined.
Lunar Energy, run by ex-Tesla govt Kunal Girotra, seems to be one of many first next-generation photo voltaic firms centered extra on electrical effectivity than era.
Lunar is an early model of a coming wave of photo voltaic firms that may more and more department off from photo voltaic era to power administration, offering a far stronger ROI for his or her merchandise.
This week let’s speak about how the transfer to photo voltaic will change how we handle electrical energy, and the way home equipment are made. Then we’ll shut with my product of the week: the brand new Dragonfly Folio from HP.
The Problem With Solar
Solar power is reasonable. Actually, it’s free however, sadly, the know-how we have to use it’s something however. My final set up which was closely backed by the California and U.S. governments nonetheless set me again almost $30,000 — even after the subsidies — and my present system is nearer to $100,000.
The direct profit is that through the summer season my energy invoice has gone from over $700 a month to below $50. But the winter is a distinct story. You see, solar energy is pushed by solar. In the winter when the solar is decrease on the horizon, it doesn’t convey as a lot energy to the panels, however you continue to want power to warmth the home.
Granted a lot of my house is heated with fuel now, however I wish to go all electrical. It nonetheless reduce my power invoice by almost two-thirds, however photo voltaic solely works through the day and when the solar is out. So, you want some type of different energy supply if you do not need to go darkish at night time or on cloudy days.

If you stay grid-tied, with out batteries, if energy goes out even in the course of a sunny summer season day (because it did for me the opposite day) you’ll nonetheless lose energy. Batteries usually are not solely costly, however you have to additionally pull sufficient energy to each cost them and energy your own home through the day, growing your want for extra solar-sourced energy.
Now should you stay on-grid, you’ll not need to pay this each night time however solely while you discharge the batteries throughout an outage. If you go off-grid, it means you will want round 30% further capability.
But what should you additionally centered on bettering effectivity?
The Promise of Firms Like Lunar Energy
This is the place these subsequent era photo voltaic firms are centered: much less on producing power and extra on growing the effectivity of power use. While Lunar Energy seems to be engaged on extra environment friendly whole-house batteries, initially their general effort is extra centered on effectivity than era.
If you can also make your house extra environment friendly, you don’t want as a lot photo voltaic or as many batteries. This effectivity focus works whether or not you might be photo voltaic powered or powered from {the electrical} grid. You may use an power administration system no matter the way you supply your energy.
You may additionally probably do issues like energy down your chargers when the batteries they’re charging are at full capability and solely energy them on once more when these batteries are beneath 50%. This would assist the batteries last more and probably scale back each day power use.
In the previous, checks of the Energy Star ranking system confirmed enormous holes of their course of. This administration functionality would additionally spotlight home equipment which are wasteful, drive equipment producers to enhance their very own power effectivity, and catch those who may nonetheless be gaming the system.
Next-Gen Solar Appliances
Now there are firms like Sundanzer which have constructed home equipment for off-grid houses for years, however the options and capabilities of those home equipment remind me of what my grandmother had again within the 1960s. Manual defrost, no chilly water or ice-making capabilities, restricted capability and, for essentially the most half, nothing you’d name engaging. But they’re extremely environment friendly.
A D V E R T I S E M E N T
What I anticipate with the subsequent era of home equipment from firms centered on photo voltaic houses blends the effectivity of the off-grid choices with the capabilities and look of the present era of contemporary home equipment — so we are able to have the options we would like at close to the effectivity of an off-grid product.
Wrapping Up
Lunar Energy is likely one of the first of a brand new era of photo voltaic power firms centered extra on the environment friendly use of power than on its era.
I count on that by the tip of the last decade we are going to see totally new firms coming to market with more and more environment friendly home equipment, extra superior dwelling power administration methods, much better whole-house battery options, and a extra complete method to inexperienced power era and use.
We are simply initially of this photo voltaic power wave. Over the subsequent 20 years, kitchen and residential designs will change, home equipment will change, and we might be utilizing AI to make sure the environment friendly use of each watt of power we generate. Altogether, this effort ought to lead to a large discount of inexperienced home fuel creation and a giant step towards countering international local weather change.
HP Dragonfly Folio G3
I get to overview lots of laptops over the course of a yr, and one which constantly has been my favourite is the HP Folio. This line has gone by means of various iterations. It began out as a consumer-focused gadget, drifted into enterprise with the Elite Folio that I’m utilizing to put in writing this, to the launch of its successor: the HP Dragonfly Folio G3.
The Elite Folio mounted my greatest criticism with the Folio which was the odd colours. It got here in brown and burgundy, and I’m certain the 80s wished their colours again. But final era, HP moved to black, used the up to date Qualcomm Snapdragon processor and graphics, and improved the pen dock and sim slot. With all of that, the Elite Folio turned my go-to laptop computer for the yr.
Well, I simply met the HP Dragonfly Folio G3 and now my outdated Elite Folio feels sadly outdated.

HP discovered that IT patrons simply didn’t need to threat a Qualcomm product. While that chip has labored tremendous for me — and I actually appreciated the huge battery life — different customers complained about it being laggy. This is because of having to run an x86 emulator which pulled efficiency from a component that was performance-constrained to start with.
In addition, Intel has satisfied IT patrons that they want vPro despite the fact that most at present don’t appear to make use of that functionality (Microsoft is working to make Windows work with ARM natively which ought to ultimately tackle the efficiency downside with Snapdragon).
So, the HP Dragonfly Folio G3 has improved the digicam, added a privateness display possibility, and whereas it has taken a battery life hit, it’s noticeably sooner (Qualcomm’s Snapdragon half leads the trade in battery life).
In brief, HP took my favourite laptop computer and made it higher, so I’m in love once more, and the HP Dragonfly Folio G3 is my product of the week.
