San Jose, California Solar Install – LG Panels + Enphase Microinverters

Posted by YES on April 16, 2018 in Enphase Installs LG No Comments

In San Jose, California, we installed 19 LG 330 watt panels. We paired this system with Enphase microinverters. In terms of real world production, we expect this system to produce 9494 kilowatts of electricity in its first year, which will offset the customer’s electric bill from PG&E though a program called Net Metering.

With Enphase microinverters, each solar panel literally gets its own solar panel. Since each solar panel becomes autonomous, the production of one does not affect another. This means if 1 panel fails, the rest of the system will continue working. We will work quickly to get any defective microinverter that is under warranty replaced as quickly as possible. And know how your entire system is performing with Panel Level Monitoring, included with all Enphase solar systems we install.

Moraga, CA Solar Install – LG Panels + Enphase Microinverters

Posted by YES on March 9, 2018 in All Black Solar Panels Enphase LG No Comments

In Moraga, California, we installed 25 all-black LG 305 panels. We expect this system to produce 8442 kilowatts in its first year. Production is lower than what is typical because this customer’s home is surrounded by trees, causing shading. Without shade, we expect this system would have produced 12,573 kilowatts of electricity in its first year.

We installed this system using Enphase microinverters. Rather than one big inverter on the side of the home or building, each solar panel will literally has its own inverter underneath the panel. Since each panel will be independent of the next, each solar panel maximizes its production individually. If a panel is shaded, the shade only affects that particular panel, not the entire system.

Also, if one microinverter fails, the rest of the system will continue to work. This customer’s solar system will still be 96% running. We will work quickly to get that microinverter replaced to get the customer back to running at 100%. In contrast, if there was a big central inverter and it went down, the customer would be at 0% production.

Best of all, the customer can view production by the panel from either the computer or a mobile device and get proactively alerted for any potential issues.…

PG&E to MCE Transition – For Contra Costa County Customers

Posted by YES on March 2, 2018 in MCE PG&E No Comments

If you live in the following Contra Costa communities:

• Concord
• Danville
• Martinez
• Moraga
• Oakley
• Pinole
• Pittsburg
• San Ramon
• Unincorporated Contra Costa County

You should have revived a notice that MCE Contra Costa will become your primary electricity provider (rather than PG&E). Residents of El Cerrito, Lafayette, San Pablo, Richmond, and Walnut Creek have already made this transition.

Who is MCE?

MCE is a Community Choice Aggregation. Instead of PG&E, MCE will be purchasing electricity and setting rates. MCE states that they can offer more electricity from renewable sources at lower rates compared to PG&E. For example, MCE states that 55% of their electricity comes from renewable sources vs PG&E’s 33%.

What will PG&E’s role be?

PG&E will continue to handle metering, billing, and distribution of electricity. If you need to report a power outage, for example, call PG&E.

How does this affect my Solar System / Net Metering?

For solar customers, PG&E bills once a year for electricity. Some taxes and fees are still billed monthly, but the electricity itself is billed annually.

MCE, however, bills solar by the month. If your system produces more credits than used, those credits will keep rolling over indefinitely, up to $5000.…

Alamo, CA Solar Install – LG Panels + SolarEdge Inverter

Posted by YES on February 16, 2018 in LG SolarEdge No Comments

In Alamo, CA, we installed all-black LG panels with a SolarEdge inverter. While the surrounding trees do cause shading, the SolarEdge inverter is able to individually optimize each panel, allowing each to produce at its own maximum. Even if some of the panels are shaded, it does not affect production for the rest of the array.

Morgan Hill, CA Solar Install

Posted by YES on January 26, 2018 in Enphase Installs Japan Solar No Comments

For our solar installs, we serve the entire Bay Area as well as the Central Valley areas directly to the east. This includes southern Santa Clara County, where the city of Morgan Hill is located. Here, we installed 19 Japan Solar all-black 280-watt panels. These panels are paired with 19 Enphase microinverters. We expect this customer’s solar system to produce 9971 kilowatts of electricity, enough to offset their electrical consumption.

With Enphase microinverters, each panel literally has its own inverter. If in the rare chance a microinverter were to fail, production will still be at 94.7% until the microinverter is replaced. In contrast, if a single central inverter were to fail, that means 0% production until the inverter is replaced.

And the the customer can monitor their production online – by the panel, on any device.

Hayward, CA Solar Install

Posted by YES on December 29, 2017 in LG SolarEdge No Comments

Solar install in Hayward, California. This solar system contains 16 LG 320-watt panels with a SolarEdge inverter. Total system size is 5.12 kilowatts DC. We expect this system to produce 7,518 kilowatts of electricity in its first year.

With Net Metering, solar customers are billed annually for electricity (though some taxes and fees are still billed monthly). This means solar can offset the night, cloudy days, and other times when there is less solar production.

Avoiding the Christmas Lights Bill Shock

Posted by YES on December 1, 2017 in Energy Savings No Comments

It is now December, and the holiday season is upon us. December is also a mont of high electricity usage.

In addition to more gatherings and parties (increased usage of lights and appliances), many are putting up their holiday lights for the season. But how much does it cost to light up a house? And what can be done to reduce the amount of electricity consumed? One way to save is to switch from incandescent to LED Christmas lights.

Many have been using the same strings of Christmas lights every year. These older lights are more likely to be the energy inefficient incandescent lights. A typical 100-light string consumes 50 watts of electricity per hour.

Assuming this string is lit daily for 6 hours over 30 days, each will consume a total of 9000 watts, or 9 kilowatts of electricity. And if 20 strings are used, that’s 180 kilowatts of electricity!

In California, electricity tends to be more expensive, and it is not uncommon for utility companies to charge 32¢ per kilowatt. That means lighting up for the holiday season using the older incandescent Christmas lights, assuming 180 kilowatts of electricity is consumed, could be $57.60.

So what can be done to reduce the amount of electricity used?…

Solar Eclipse – Solar Monitoring

Posted by YES on August 24, 2017 in Uncategorized No Comments

The solar eclipse might be over, but there is still one more place to see its impact. While we in California might have only seen a partial solar eclipse on Monday, that doesn’t mean that we were unaffected. If you have a solar system, check out your monitoring portal and see the drop in production coordinating with the hours of the partial eclipse. The peak of the drop was at around 10:15 AM, the same time that the partial eclipse peaked.

Pleasanton Solar Install – American-Made SolarWorld Solar Panels & Enphase Microinverters

Posted by YES on July 5, 2017 in Uncategorized No Comments

A solar install in Pleasanton, California. This system consists of 32 SolarWorld 290 Mono Black panels, an all-black panel. SolarWorld panels are manufactured in the USA at Hillsboro, Oregon (located just west of Portland). The system is paired with Enphase microinverters. We expect this system to produce 11,488 kilowatts of electricity in its first year.

With microinverters, each solar panel has its own inverter. The major benefit of microinverters is for the rare chance that there is a failure in either one of the microinverters or panels, the rest of the system continues to make electricity unaffected. This is unlike central inverters (large single inverters), where a failure of the inverter will result in total production loss. And with our 25 year labor warranty, we will coordinate with the manufacturer to get the system back running fully.

And with panel-level monitoring, the customer can view how the system is performing, down to the individual solar panel, from anywhere with an internet connection.
