Solar newb question! 24v panel into 12v system?

Solar newb question! 24v panel into 12v system?

Excited to finally take my electricity off grid for a tiny trailer home! Researching setups, struggling a little with details:

I've a 240w 24v panel readily available. I've two great 12v batteries. I am in the pacific northwest where full sunny days aren't the norm during winter months.

Some things I've read suggest that a 24v panel charging a 12v system may be more efficient than a 24v system when cloudy days are frequent.

12v inverters are cheaper than 24v inverters—but 24v panel for 12v system needs more expensive mppt controller for efficiency?

So, I could go with a cheaper charge controller but more expensive inverter and run a 24v system?

Which would make the most sense for PNW living?

THEN Pure sine inverter or modified wave? Charging computer and phones. Are modified wave inverters actually dangerous for our fancy (not medical) electronic devices?

Thanks, communty, for whatever guidance or suggestions you may offer!

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6

PG&E Aggregate Net Metering Application Help

PG&E Aggregate Net Metering Application Help Earlier this year I completed a ground mount at a ranch in Paso Robles, CA.

Does anyone have any contacts for professionals who I can hire to complete this process for me? Or any tips for completing this process? Honestly, this issue has become the bane of my existence and I need it solved. Any help is greatly appreciated.
