I get into a lot of debates with people who fall for the seductiveness of Solar PV panels as a panacea.
“Just put ’em on every rooftop and we won’t need fossil fuels anymore!” Uh huh.
Unfortunately, there is a TON of bad information when it comes to energy and power out there even among professionals.
“Pedro Pizarro, president of Edison International, made a very unclear statement that ‘California would need 10 gigawatts of storage for California to cut greenhouse gas emissions 40% by 2030.’
“It is unbecoming of the leader of Edison International to fail to distinguish between power (in GW) and energy (inGWh). You don’t store power any more than you store miles per hour; you store energy.
“Car batteries typically STORE 1kWh of energy but can supply 7 or 8kW during cranking in cold wealth supply and are recharged by alternator with less than 1kW.”
Notice the difference between power and energy.
A 100Watt PV panel may put out a 100Watts…at max capacity. But what does that mean exactly?
That means it will provide 2.4kWh a day. (Of course it won’t, but just for this exercise consider it.)
The 2.4kWh is actually what I’m most concerned with. I calculate my energy consumption not by kW but rather by kWh/day. THus if my energy consumption is 10kWh/day, I’d need about 4 100 Watt PV panels putting out 100 Watts per day for 24 hours consistently.
Again, your 100 watt Solar PV panel is NOT putting out 2.4kWh/day. But that’s for another post.
Here’s my Youtube video discussing the book I show above:
