Induction cooktops
#11
Snik...

I too had to make choices based on available space. My roof is 7’ wide and 18’ long. I have two roof vents, two solar panels (325 watts each...but, I did have 345 watts up there originally). And a passive solar hot water heater.

I installed lithium batteries. Smaller foot print, less weight, much greater capacity. And, I do not need A generator...saving space and avoiding having to carry gasoline.

I have a 2000w inverter/charger. I run the induction surface a few minutes each day...even in December I get enough sun to replace the battery loss. At 150 AH to run...that is just 12.5 Amps to run for 5 mintues. That is more than enough time to bring anything to a boil....as you point out, it will bring a boil really fast. Like with pasta...you can turn it off and cover it...it will coast to done without having to boil the whole time.

For longer term cooking, I rely heavily on my solar oven.

I have those pictures in offline storage now...but you can go over to the other site and look up conversion project for honey.

All it is is just black hose in a coil. It is held in place with a frame...then the whole thing painted black and coated in UV protection.

I got the idea from a friend who uses a series of black hose coils to heat his swimming pool. Just pays for the electricity to run the pump, which he has to run anyway.

So I would need larger capacity solar panels, a bigger investor and a couple better batteries. It might end up a space trade off though. But then again it would be just one system to try to keep track of with the super sized panels, etc.

I learned a new trick. I was heating some meat to go on a tortilla. My tortilla was cold. After the meat was hot, I put the tortilla on the cook top and put the pan over the tortilla and it warmed. It was on a fairly low cook setting. I had to keep moving the tortilla to get all of it warm. Then had to clean the cook top. Nothing burned Bottom line was I had a warm lunch.

Another trick 
I was trying to heat a piece of pizza on a griddle. The pizza top was not getting warm so I put a big bowl over the griddle. A magnet sticks to the bowl so it must conduct a little. Anyway I have a little oven now!
