The idea it to use a small solar panel to generate electricity, which will be sent to an element (or other device) which will heat up water producing steam. This steam will turn a turbine generating more electric than the solar panel would manage alone. This is fundamentally a poorly thought out idea. Energy is a conserved quantity, so at each step of the ...

"The idea it to use a small solar panel to heat up water producing steam." Nope. First sentence being wrong makes the rest of your obscure post not worth paying much attention to. Small solar panels will have an efficiency on the order of 25% at best, while a direct heater such as a mirror, will have heating efficiencies on the order of 60 to 70%. ...

An alternative to your proposed approach is the "online UPS" strategy: Connect the loads to the battery. Connect a mains-powered battery charger to the battery. Connect a solar battery charger to the battery. And that's it — no switching devices at all. It's the same way a car battery system works — there's one circuit that the battery, charger (...

Should this be your schematic, it would be quite okay.

I finally got my device to turn on without using a battery source. I have charged the capacitor to a certain voltage, then had a switch to connect to the load when above a certain threshold. To do so, I needed to break down my calculations to Energy (Joules/sec). My device can turn on for at least 2 minutes before shutting down and having the capacitor to ...

Depending on the laptop, the task may be as simple as 150W/24V solar panel + voltage limiting shunt for 150W/19V or 20V (where most laptops work) + the proper jack to get the power into the laptop. No MPPT, no inverter, shunts are way cheaper and simpler than MPPT or PWM controllers and the laptop will use whatever it can, depending on the available sunlight....

Your plan is generally reasonable. Needed current ratings all depend on the voltage of the batteries; I'm guessing that you're thinking of a 12 volt battery, but for a solar power system that isn't connecting to any other DC equipment meant for auto use, you should consider 24 or 48 volt nominal voltage to get more efficient operation and not need quite as ...

If this can heat up a liter of water in under 10 minutes that would be great, but it is not necessary. $$P = \frac {m \times \Delta T \times SHC} t$$ where $P$ is power (W), $m$ is mass (kg), $\Delta T$ is the temperature rise (°C), $SHC$ is the specific heat capacity of water and t is time (s). So boiling water from 20°C requires:  P = \frac {1 ...

You have just described an electric kettle. They are cheap and readily available. You haven't said anything about the voltage or current. European ones are likely to run on around 220 to 250V, and require around 10A. The heating element won't care if the supply is AC or DC. But if the kettle has an automatic switch to turn it off when boiling, then this ...
