- Curious about whether solar energy can power your home with solar panels? Look no further! In this bright video, we dive deep into the potential of solar power in Southern Alberta's unique climate and landscape. Join us as we explore the feasibility, benefits, and considerations of harnessing solar energy to meet your household's needs. Whether you're an eco-conscious homeowner or simply intrigued by renewable energy solutions, this video provides valuable insights to help you make informed decisions about integrating solar power into your life. Don't miss out on the opportunity to unlock the power of the sun right at your doorstep!
i live in the SF Bay Area. Good weather. I have a 1903 house that was uninsulated. So I insulated it and added 3.9 kW peak of solar, that's 11 panels. As I am under NEM 2.0 I won't need a battery for 18 more years as I am grandfathered in and can use the grid as a battery. I made all of $199 dollars last year. I expected my bill to go down, but not turn negative! And the house is all electric: heat pump heat and cool, heat pump water heater, induction cooktop, etc. Surprised me... pleasantly. I should note that almost all of my power comes from renewables: wind, solar, geothermal and hydro. Did you know that California is the greatest producer of geothermal energy (from boiling hot brine) in the US?
I shall leave a comment. I like solar energy. We need some kind of physics revolution to find a better way to store energy.
I am in favor of the green energy known as Nuclear Power.
Simple answer is no, you cannot power your home with strictly solar.
Depends on where you live and your battery capacity. But yes, strictly solar will be hard or very expensive.
No, it cannot. You have to have a grid connection. The battery alone would cost more than the house.
The efficient home builds can use 1/10th of the energy of your average home or less. You could go off grid but why bother if you get paid for the excess energy that you couldn’t use anyway 😅
That's not true! DIY LFP battery build is cheaper than ever.
@@Playingwithproxies Why go off grid? Because you are using the grid as a battery, which it is not. The grid "battery" is FUEL from a coal, gas, or nuclear plant, with some Diesel to top it all off.
Once everybody has solar, you will be paid zero... In fact, California is going to charge to have solar PV on the grid. What then? Pay to give them free electricity? Makes no sense.
You stated you have a shortfall for 4 months. How much battery do you need to be off grid? Be honest...
Most would need at least 30 days. The problem (800 LB gorilla sitting on your face) is that a battery is good for 5000 cycles (maybe). That is 13.5 years. If you add two days, you double the CO2 as the life is around 10-15 years. Three days...triple. 5000 cycles is 40 gCO2/kwh. 10 days is 400 gCO2/kwh. Gasoline is 300. 30 days is literally 1200 gCO2/kwh which is much more than Coal at 960. If CO2 is the reason, then a battery cannot work. And neither can solar PV and wind.
A 100% RE grid needs to be overbuild (Tony Seba from Stanford RE U-curve) by 4x and have battery costs of 3.5x, which means it costs 7.5x more than X the average yearly load. Making fuel costs 1.5x. 7.5/1.5 = 5 times MORE to charge a battery or use electricity from a 100% RE grid than to make fuel OFF grid.
KEY is OFF GRID. New solar thermal tech and new combustion tech will allow 20-60 times lower cost energy and fuel making.
A wind/solar PV/battery/EV system can NEVER be CO2 neutral, if that is your goal, and they will be 20 to 60 times more costs.
I explain this on twitter (x) @seaplaneguy.
BTW, my house (2400 sft roof) and shop (1200 sft roof) can give me all thermal (heating and cooling) loads and electricity, plus 100,000 miles (160,000 km) from my house with no grid or oil. That is the future, not a bunch of junk solar PV panels that look like a cheap science project.
@@meilyn22 Do the math. My math says a battery would cost $2 to $6 million for 30 to 90 days. The space for 90 days is equal to may shop, LOL. It won't work. Wake up.
@@seaplaneguy1 Why would you stay on just battery for 30-90 days without recharging? Sounds dumb to me.
