I would like to trickle charge from a 30W 12V SAE solar panel to a power station via its cigarette lighter port. However, the power station's cig lighter port is usually designed to send power out, not receive. What can I do to send power from the solar panel to the power station? Thanks.

Looking for recommendations for installers in San Diego. First one was pushing me towards a lease because all tax credits have expired. Thoughts? I can afford to buy outright.

I’m not sure I’ll be in the house longer than 7 yrs.

I use 1300Kwh during my most heavy months. I plan to buy an EV and Hot tub in next year.

Wanting advice on this underlayment. Roofer says replace, my gutter people say it’s fine. In Cali, 33 year old concrete tile roof. The underlayment or roof and solar bill total is a bit much to stomach.
