Peak load of households is not during peak solar power generation. Households installing pv isn't a solution to what you described.
Today, you could also use a battery to buy power during mid day and use it in the evening when you need it the most.
In moderate climates in the US, peak loads are typically the hottest and sunniest hours of the day since condenser units are the most energy-hungry appliance in most homes. Clouds notwithstanding, peak solar generation would typically align (or closely align) with peak load time.
Batteries would also help a lot - they should definitely be subsidizing the installation of those as well but unfortunately they aren't yet (at least not in my state).
This is incorrect. Look up the “duck curve” or if you prefer real-world examples look at the California electricity market (CAISO) where they have an excellent “net demand curve” that illustrates the problem.
I watch big state and national grid loads (for fun) and I see two distinct peaks: 7-8AM when everyone goes to work, and then around 5-7 PM when people commute home and heat up dinner.
Otherwise it's a linear diagonal curve coinciding with temperatures.
I personally try to keep my own energy usage a completely flat line so I can benefit from baseline load generator plants like nuclear (located not that far away).
If you consume energy during peak hours you are a peak load consumer. Consuming in other hours doesn't change this fact.
Your personal energy use pattern does not determine where you are drawing your power from, wtf logic is this?
