Invest in a battery for any solar.. Learn about the interface. They come in various models. If you have a well pump, make sure it's a slow starter.
Batteries help undo some of the whole net-metering entanglement. But, you need to know a simple list of stuff. Like, if they get drained, will the sunlight trigger the solar modules to wake up the inverter? If you have neighbors with a similar system, wifi can overlap! Consider the advantages of hard wire.
Never accept a damaged battery.
We've had experience with boilers, gas lines, pilots and all sorts of old-style equipment post the era of chopping wood. Start small and you'll enjoy the difference. Don't buy a big system and forgo the battery to save money. Get fewer modules and use your power if the utility has a glitch. If you have no batteries, the utility shuts off your system as it can backfeed down the line and hurt a repairman.

I'll keep you posted - on the other online community thread that we originally discussed this on!
Thanks so much,
Ella

I am curious of your vector on that.

KISS has been on my list to help create a draft infographic! I'll try to send you a draft soon, @william fitch!

Ya. Its one of those that had its look in the sun, so to speak. KISS and preferably not moving (PV) are ideal guidelines. Things that move at a high rate of speed demand accelerating precision as the speed increases. At the opposite end of the kinetic scale is filling rail cars with heavy ore and powering it up hill to collect energy, and run it downhill to exit the energy. Actually a safer bet. The closest and best gened energy is PV. No moving parts. They just need to get the efficiency to 50%. Get that far and everything changes, along with room temp super conductors. Different world.
Complex design makes for good profit. KISS makes for good engineering.

I know very llitle about this but Irecall that very high amounts of energy (momentum) can be st;ored on flywheels, very large heavy disks that spin at high rpm, on axles supported on ball bearings, in an enclosed container (do not want this thing to fly apart out in the open) and the container is air evacuated to near vacuum. Very little friction loss. How could this be used? Stationary Vehicles. I know not from whence I speak; I am a lawyer, not an engineer. I would like to hear any thoughts on this.
