Two questions about solar power and MPPT regulators

Hi

Two quick questions:

1. anyone have any experience with solar power in the pacific northwest/southwestern B.C. and what to expect in AH/day for, say, a nominal 130 watt panel? not wanting to live aboard just looking at minimizing engine use for recharging for 2 week trips.

2. i understand how MPPT regulators more efficiently use overvoltage, but can anyone tell me if they can also use their DC to DC converters to get a small current into your batteries when they are at undervoltage?

thanks muchly in advance
