I recently got my roof replaced which caused me to remove my solar panels. I called the installer and for a hefty fee they removed and reinstalled my solar panels.

I asked the company if it was possible to expand my system and they said no due to location of my home and how the roof is oriented I wouldn’t get much benefit adding more panels. Next I asked how much a battery system would cost and the installer gave me a price of 22M sats ($20k).

Very pricey for “green” tech but from a self sovereignty perspective I may just pull the trigger sometime in the next 3 to 5 years. The power goes out here constantly and having a system that can serve as a de facto back up generator sounds really nice.

Attached is the cut sheet the installer provided. It is an enphase system.

What do you think stackers? 22M sats a fair price for a whole home emergency power system?

It depends on how many accumulators (measured in storage units) are recommended for 22M sat. In Europe (and I think elsewhere too) the price of accumulators is about $1000 / kW (this includes installation and commissioning). As for solar panels...don't believe that it's not worth installing more...solar panels FIRST and foremost don't need heat, but light. The only decisive factor is the inverter (central unit of the solar system). This is usually overloaded by about 30-40%, but it is not recommended to overload it more than 25%. (for example, if you have a 10 kW inverter, you can add a maximum of 12.5 kW of solar panels). If you want more than that, you need a larger inverter.

A system like that?

Seems pricey but it’s a long term investment and likely value accretive to the home.

22M sats? That's a lot of money, even though everything probably seems cheap compared to Bitcoin. But for those solar panels and battery system to pay for themselves, it's going to take years and years, and both of them will lose performance over time.

How many things do you have that you "need" a battery system like that for?

You could buy a lot of batteries and inverters for that price, and if it's just your fridge or starlink that need to stay on, you almost certainly don't need to spend $20k for infrequent power issues.

Lights, water heater, stove, fridge, freezer,

Your creature comforts may be worth lots of sats... mine are not, so i would say that Freezer and Fridge are the only "need" items in that list given that food can spoil quickly.

You can boil water and cook with a propane cooktop & propane never goes bad... $1000 will get you a VERY long way.

Now you need what... 2 hours of backup for your fridge and freezer? or maybe it's a whole day?

If your power is going out for more than a day on any type of regular schedule, I would begin looking for a new home or getting a diesel generator instead.

Batteries are not suitable for electric heating devices.

Thanks for the feedback

Would it help with any sort of peak pricing issues?

I don’t think so. My system isn’t large enough to be 100% off the grid. I was thinning this would be more of resilience upgrade to the home. Once the power goes out we lose access to everything!

I was wondering if there's a way to draw from the battery while prices are elevated. I'm not sure if you have peak pricing, though.
