Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently.
Is this just the cost per raw Watt produced?
Is it a fair comparison vs conventional fuel-based power (coal/nuclear)?
Ie: if you wanted to build a plant capable of producing continuously, 24 hours a day, you would need some multiple of solar panels to produce an excess during daylight, and storage.
Not that drastic drops in solar costs aren’t bad, just what would the cost-per-watt be if you had to power an average city on just solar for a year?
Look at the subtitle on the chart, it’s levelized cost over the generator’s lifetime. So not including storage for any intermittent source like solar or wind
And not including the financing cost of buying up an this upfront.
I’m buying 36kWh solar array and it will be home made diy, used.parts and maximum jank and don’t paid upfront because that’s the only way it makes economic sense and that’s hoping it works for more than 7 years (break even point at my insolation level and and grid price (8.8$cad/kWh) and it only works with net metering)
Levelized cost averages the fixed costs over the lifetime of the generation
They’re generally comparing utility scale installations, not home rooftop solar though.
In my area, you don’t get any government incentives unless it is professionally installed. They get you coming and going.
Yes, I never even considered the subsidies, I know it’s not for me.
Anybody can claim the tax credit though. When you file the taxes it’s a box you enter a number into.
They don’t ask for proof, but you’d better keep your receipts just in case.
Hmmmm, interesting. Thanks.
Well you’ll never get a “fair” comparison, because the environmental effects are never properly priced into the consumer price.
