Do these solar panels look any good?

I avoid using inverters on my system whenever possible, and instead use dc to dc converters to avoid the massive power loss as LS has stated.

I use a 12v dc to 19v dc step up converter to charge laptops that are rated at 19v dc, which most full size ones are. Using this method there is only a minor power loss compared to using a 240v ac converter then stepping back down to dc using the device's local power supply.

For devices 12v dc and below I use a 12v dc to various dc voltage ratings, from 12v dc down to 1.5v dc, and the input connects to my battery via a standard male to female cigarette lighter plug and socket set up. The output connects directly to the device's dc input socket using the relevant universal plug adapter and switched to match the device's dc input rating.
