Solar panels. Took about 6 months since starting the process and still need certificates before I can sell on a smart tariff but it's been fun seeing electricity generated even in December!

Been Looking into it and seems uneconomical (in CA) to pay equivalent of 16 years worth of electricity cost upfront just to set up panels.

How did you come around to this ?

If someone is quoting you 16 years for ROI on your panels, get another quote. Even a decade ago I was able to get an ROI of 7 years. And panels are cheaper now. (Labor is not.)

Actually got 3 quotes all in the same range. The economics did not make any sense. Makes me believe somethings off with this vendor ($1500 per 350 Watt panel + $2500 install).

Factoring in the NEMS3 change [1], and that we just bought our house draining our reserves, it's close to getting dropped.

Net metering got scrapped and subsidized rates are out so it’s not a good deal anymore

I'm in the UK and spent a little over £10k for 6.5kW and batteries. Expected payback is < 7y, depends on (UK) electricity prices and possible smart reselling power.
