PV Gap

Clifton Said:

Is there a good Solar Panel for a power outage emergency?

We Answered:

Here's portable back-up Solar power system for $1749. You can hook up additional flexible solar panels and option to connect inverter directly to your car lighter to charge for more power usage.

Jo Said:

do all solar panel systems require batteries or converters?

We Answered:

Pretty much any system to generate electricity for general use will have either batteries or a grid-tied inverter. That's the only way to get consistent power at night and when it's cloudy.

For noncritical applications like water pumping, there might be some systems that skip the batteries.

Laura Said:

what is the best angle and direction to mount a solar panel?

We Answered:

Depends on where you are in the country/earth, but generally electrical solar panels are located on the south side of a sloping roof or at an angle that is roughly half way between the high and low points of the sun (summer and winter). Solar heat collectors are usually aimed some what east of south to pick up heat earlier in the day and are aimed lower to get heat directly in the winter and more indirectly in the summer.
