The best panel angle for solar in San Francisco Bay area is discussed in our forum:

“The rule of thumb is to mount the PV modules (panels) at the latitude of your locations. There are some caveats.

It is a good idea to have the panels at about 10°, even if near the equator. This prevents water from pooling, that contributes to soil and even mold build up.

The weather impacts production. For example, Sacramento CA is about 40°. Setting the panels at this angle is best for winter, but in the winter it rains, so a better angle is actually about 26°.”

Example solar panel system in the Bay Area

Blue Ribbon Supply Company in South San Francisco have a 36.3 kW rooftop system system, which is publicly available via the Enphase Enlighten portal allowing us to see the output of the system. The system is installed due south, with a very small pitch of just 5° (nearly flat on the roof), using Enphase micro inverters, and Sharp solar panels (ND-216U1F Sharp).

The graphs show actual energy output in 15 min intervals.

REC Alpha vs SunPower A Series

“I am in the San Francisco area in California

After tax rebates and incentives, the difference shrinks down to $3500 between SunPower and REC panels so closer.

The REC dealer is gently but consistently pushing Solar Edge with power optimizers and says that the Envoy Box accompanying the Enphase microinverter system will need to be replaced after 5-10 years. (The warranty is 5 years whereas all other parts of the system are 25 years.) Is this a common maintenance that needs to be serviced in the life of Enphase microinverter systems with monitoring? I haven’t heard this at all from the SunPower dealer so is this because the “customized” microinverters Enphase supplies to SunPower somehow bypasses this problem?”

Solar Panels and Inverter for best ROI

“You mentioned Qcells, It think they would probably be a good balance of quality, performance and affordability. Obviously you would get more generation from using high efficient SunPower or LG, but it would push out the payback period. They might work out to be better ROI in the long run though, not sure, would be interesting to calculate that.”
