Power

How do you keep the power up in overcast weather if out for a couple of days

Switch a few things off.

or put a few portable solar panels out and play "chase the best spot" for the day to make up for the roof top solar short fall. A clamp meter on the portable panel lead will give you an instant read out of the optimum position at the time for each panel, it's not always where you think it would be either due to cloud reflection from nearby water or snow..... the snow bit not so often on the big island

So if ya have a few plops of bird poo on your panels,or A single panel, does that panel go dead as I have heard in my sheltered solar life, or is it just where the poo is that ya get that foot print bit of power less...???

or is that just house panels on ones roof at home

Turn on the generator.

it would depend on how big the bid is;

A long time ago, there was a bloke on Naru who had a job for life cleaning panels. - not so much now

It would only reduce the amount of energy coming from the panel, just like when a cloud comes over, but constantly until you clean the panel. If you use an mppt controller, they will provide much more energy on a cloudy day, than a pwm controller. Have parked under huge shade trees on really hot days at the same place many times over the years and when previously using a pwm controller got little input, but the mppt, always puts much more energy into the pack.

Down here in Tas, (before lifepo4) used to have trouble having power at night in the middle of winter as the sun is so low and the panels sit flat on the bus roof. When changed to mppt, the problem was much less and since lifepo4, don't even think about it, as we always have enough power.
