John Bergh: Skill Synergy

By James Florence, Diamond Certified Resource Reporter

DAVIS — Having acquired a number of practical skills in his early life, John Bergh was surprised to find an industry where he could incorporate them all. “Growing up in the Clarksburg/Yolo County area, I used to help my dad with things like drilling water wells and servicing farm equipment,” he says. “In addition to gaining a familiarity with water pumping and electrical service, I got into roofing in high school, which widened my range of experience. Later, when solar energy started to become more mainstream, I found that my knowledge of roofing, electrical work and water pumping were all applicable to that industry.”

Today, as owner of Sun Metrics, John says he appreciates the many positive attributes that his job entails. “Installing solar is really gratifying work. It saves homeowners energy and money, and given the current energy crisis and our reliance on fossil fuels, it’s just the right thing to do.”

A resident of Aptos (where he lives with his wife, Katie, and their three sons), John says the local setting provides ample opportunities for outdoor recreation. “My family and I are avid outdoors people. Whether going to the beach at Rio Del Mar or hiking at Nisene Marks, we love enjoying the beautiful weather and scenery.” John also pursues his interest in sports, whether personally participating; coaching his sons’ teams; or being a spectator at professional football, baseball and basketball games. Additionally, he enjoys performing automotive work. “On any given day, you might see me tinkering with a motorcycle or old sports car in my driveway.”

In his life and career, John espouses the importance of professional integrity. “I think you should never ask someone else to do something that you’re not willing to do yourself,” he says. “When it comes to my business, I’m willing to do anything that I ask of the people I work with, which fosters credibility and mutual respect between us.”

When asked the first thing he’d do if he could retire tomorrow, John says he’d go back to work. “I’ve tried the vacation thing, and it’s not really for me,” he laughs. “If I retired, I would need to stay busy, which is why I’d probably volunteer more with coaching youth sports or go into some area of teaching.”

Ask Me Anything!

Oakland A’s, the San Francisco 49ers and the Sacramento Kings.

Q: Did you play any sports in high school?
A: Yes, I played baseball, football and basketball for Woodland High School.

Q: What was your first car?
A: A 1972 Volvo P1800. I still have it and it’s my favorite car!

Q: Music or talk radio?
A: Music, especially ’80s rock and new wave.

Q: What’s one website you visit on a daily basis?
A: Sunpower.com. It’s definitely one of the best solar resources on the web in terms of interactivity and content.

What To Ask In Person
Interview Local Solar Contractors in Person

Some questions simply cannot be answered until a qualified site assessor visits your home or business, as the quality of sunlight can vary significantly from site to site.

  • How will the solar site assessment work?
  • Is my home or business site better suited to one type of solar power system over another? If so, why?
  • If my site is suitable for solar thermal energy generation, how much work will be required to make the array deliver heating, cooling, and hot water beyond simply getting the array onto my roof or other part of my property?
  • How does selling back electricity work in Santa Cruz County?
  • How long does a solar panel installation take?
  • When can I receive a written estimate for the solar panels and solar system installation?

  • What To Ask References
    Learn from Santa Cruz County Solar Company References

    It’s best to choose a Diamond Certified solar contractor/installer because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a solar panel installers in Santa Cruz County, you can have confidence choosing a Diamond Certified company.

    Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified solar contractor within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your solar contractor and solar panel installer.

    Keep in mind, though, that references provided to you by solar companies in Santa Cruz County and beyond are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

    That’s because references given to customers from solar companies are usually cherry-picked instead of randomly selected from all their customers. So local solar contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the solar company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    • Did you have a solar array installed at your home or business by (name of the solar company in question)?
    • Did you receive a solar site assessment from (name of the company in question)?
    • What kind of solar array did you have installed?
    • How satisfied were you with the solar panel installation?
    • Has your new solar panel array operated the way you expected?
    • Have your energy bills been reduced as much as you expected?
    • (If you have a PV array) Are you selling electricity back to the utility?
    • If so, how has the experience been for you?
    • Are you making as much money as you expected?
    • How does payment for excess electricity work for you?
    • Would you recommend that someone else invest in a PV array large enough to sell electricity back to the utility?
    • How did the federal and state incentives figure into your decision to invest in solar energy systems?
    • How did the federal and state incentives affect your ability to pay for the solar investment?
    • Do you have any advice or information we haven’t touched on yet?

Compare the estimates you were given to the final prices on the invoice. Politely but firmly request explanations for discrepancies.

Honest mistakes can be made; checking the invoice can help you see and have them corrected promptly.

This is the best time to ask your solar contractor about upkeep and maintenance for your new solar panels and solar energy system.

Solar Energy FAQ

Q: Why choose a Diamond Certified solar contractor or solar system installer?

Q: Why choose a Diamond Certified solar contractor or solar system installer?
A: Diamond Certified helps you choose a solar system contractor or solar installer with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only solar contractor/installer rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified solar contractor/installer.

Q:  Why should I invest in solar panels for my home or business?
A:  A solar array is an investment that will pay for itself and then earn a profit in most locations in the US. This is certainly true almost everywhere in California.

Q:  Solar energy seems expensive, so how can I make my money back?
A:  New financing options enable homeowners and businesses to start saving money as soon as their solar panels are active.  Every dollar you don’t spend on buying energy from a utility is a dollar in your pocket.  This adds up quickly, and it adds up even more quickly as energy costs rise.

Q:  If solar power works and can be cost-effective, why does it need government support?
A:  The federal government has supported every major energy source through R&D support and various incentives.  Oil, natural gas, hydroelectric, biofuel, and nuclear industries all have received government support and continue to receive support today because energy drives our economy.  The State of California supports solar partially to help increase the state’s supply of electricity without building new power plants and partially because solar energy can be harnessed right here in California.

Q:  Don’t I have to have lots of expensive batteries to have solar electric power?
A:  Batteries are only necessary if you want to get off the grid.  As long as you stay connected to the grid, you don’t need to install batteries with your new solar power system.

Q:  Do I have to get off the grid to use solar power?
A:  No, you can stay connected to the grid to use solar electric power.  If your solar array generates electricity, your home or business will draw power from your array first, then the grid as needed.  If your array doesn’t generate as much electricity as you need, or if it’s night, your home or business will draw what is needed from the grid.  If you generate more power than is needed, the excess will go to the grid and earn you money.

Q:  Aren’t all solar products made in China?  I want to support American business.
A:  U.S. solar installations generated $6 billion in direct value in 2010, including manufacturing sales.  Of this 75% ($4.4 billion) went into the US economy.

Q: How do I know what kind of solar array is right for my home or business?
A: The answer depends on what you want from your solar array and how much money you are willing to invest.  A small passive solar thermal array is relatively inexpensive and can provide you with heat for water and heating your home.  An active solar thermal array costs more but heats water and heats and cools your home more efficiently than a passive array.  Photovoltaic (PV) arrays are more expensive than solar thermal arrays, but you can use them to offset electricity consumption in your home or business and even sell energy to the local utility.  A Diamond Certified solar contractor/installer can help you determine the right kind of solar array for your home or business based on your specific site, your needs, and your desired level of investment.
