PV Gap

Justin Said:

What factor can be added to a regular solar cooker to make it more effective in heating water?

We Answered:

In my experience, there are several factors that increase the water temperature you can achieve:

1. insulation that keeps heat in the cooker
2. extra layers of glass or plastic with air between the layers
3. as much heavy, dark metal inside as you can manage - especially cast iron

Marlene Said:

should i get solar hot water heating?

We Answered:

Of course you can build one yourself. No electricity needed if its the thermosiphon solar hot water heater. Consult some local solar companies for the panels and the rest you can install yourself.

Calvin Said:

need to generate electricity from solar hotwater pannel, so that hot water as well as electry can be produced.?

We Answered:

there are panels that do both, however you cannot generate electricity for electric power if you have a thermal panel. besides, the panels that do both probably are not available to the public yet. ????
