[DC] How to choose the right panel/installer?

[DC] How to choose the right panel/installer?

I've received a few quotes for solar install and I'm having a hard time determining which combination makes sense for me. I'm looking at around a 7-8kW system.

I'm not sure how to determine if the SunPower panels offer enough value to justify the price over the Solaria option. Warranty and wattage being close enough, is the only real differentiator the long-term efficiency? We don't know if we'll be in the house for more than 5 years at this point, so beyond 10 years the solar only matters for resale value really.

Ignoring the reviews of the companies themselves, am I wrong in thinking that the Solaria option offers a much better value proposition than the SunPower offerings? SunPower seems very favorably reviewed, but does it warrant a .5-.8 $/W premium?

Panel $/W
Solaria 350W $3.60
SunPower 327W $3.88
SunPower 335/345W $4.18
SunPower 360W $4.44

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.
