I like the fact they did both roofing and solar. They have to do them together, if you ever have looked into the solar, you will notice companies will recommend this.

Because I'm very picky about what I have done to my home, they were tolerant of this fact and didn't mind me watching them closely. They had a good plan and are very organized.

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for solar companies that have earned the prestigious Diamond Certified award. For High Definition Solar, the key to achieving and maintaining high levels of customer satisfaction is simple: take a focused, personalized approach to every job to ensure the best possible results. “The passion and dedication we give to our clients is second to none,” affirms CEO Tim Netherton. “We want every customer to enjoy their experience with us, and focusing all our energy on their specific project is an important part of that.”

High Definition Solar has been installing solar power systems for residential clients throughout the Greater Bay Area since 2010. As a full-service provider, the company is qualified to handle every aspect of solar installations, from conducting energy and financial analyses to dealing with the paperwork and permitting processes. It also provides its clients with plans to optimize their energy savings, and it stands behind those projections with a “worry-free” solar production guarantee.

Unlike solar companies that limit their services to installing and repairing solar power systems, High Definition Solar is also qualified to offer a variety of roofing services, including dry rot repair and energy-saving upgrades. “You have to understand roofing if you’re going to do solar correctly, and that’s where we excel,” says Mr. Netherton. “We’re just as experienced and skilled in roof work as we are in solar work, so we’re able to maximize the efficiency of every installation.”

To further differentiate itself from its competition, High Definition Solar offers workmanship and product warranties that are among the longest in the solar industry. “Our power inverters and panels are covered for 25 years, and all our labor is backed for 10 years with an all-inclusive warranty,” explains Mr. Netherton. “There’s no fine print with us–if a client has a problem with their solar system, we’ll come out and service it at no additional cost.”

Industry Info

Take simple steps to get the most out of your solar power system. Having a solar power system installed on your property requires a lot of time and money, so it’s a good idea to maximize the system’s performance however possible. To get the most out of your system, consider the following tips:

  • Make sure you have high-quality equipment. Solar panels and inverters are installed as one system, and each individual piece only works as well as the entire unit. Tim Netherton, CEO of High Definition Solar in Concord, recommends installing a solar array with micro-inverters. “Micro-inverters are individual inverters for each solar module,” he explains. “They allow the panels to work independently instead of working as a row. That means instead of 16 modules in a row, you can have three or four all working on different parts of your roof.”
  • Your solar contractor should install your solar panels in the best location for gathering sun power. Keep surrounding trees trimmed to limit shade, as even minor shading can lower a solar system’s effectiveness by up to 80 percent. Solar panels are wired in a series, so minor shading on one panel can impact all panels unless they’re used with micro-inverters.
  • Talk with your solar panel provider about maximizing your panel array for your exact location. For example, locations that get early morning fog may benefit from orienting panels to take full advantage of clear skies in the afternoon.
  • Dust, bird droppings, tree branches, fallen leaves and other debris can significantly reduce the energy output of your solar panels. If your area gets a lot of dust, use a hose to clean the panels once a month. In windy areas, clean the panels every month or two. Your installer may be able to provide regular cleaning services or recommend a different company.

Frequently Asked Questions

Q: Is solar power worth the investment?

A: It’s definitely something you should look into. Every home and family has different objectives when it comes to going solar, but they all have one thing in common: they want to secure their future, even if it’s in a small way like controlling their energy spending. The easiest way to do that is to have us come out, get on your roof, determine exactly how much energy you’re consuming and let you know how profitable a solar power system would be.

Q: Shouldn’t I wait to see what new technology comes out in a couple of years?

A: No. More and more people are installing solar power systems every day, and those people are able to join the Net Metering Agreement, which means they can send excess power back to the grid and receive credits. But the race is on—once the utility companies reach their cap on solar power, they’ll no longer have to give out Net Metering Agreements. People who get in now will be grandfathered in, but those who wait might miss out.

Q: How long will my solar installation take to complete?

A: Typically, we can install a solar system in one or two days. Some jobs might require special care, such as tiles that can’t be walked on. In those instances, we may have to use a lift or other accommodations that can add time to the job, but we’ll determine that before work begins.

Q: How long will my new solar panels last?

A: The manufacturer provides a 25-year warranty on the solar panels we install, and they’re expected to last even longer.

Q: Will you take care of my roof while you’re installing my new solar system?

A: Absolutely. We’re a licensed roofing contractor as well as a licensed solar installer, so we understand the importance of working carefully when installing a solar system on a roof.

Q: Do you handle the permitting process?

A: Yes. We have a simple process that we follow every time. First, we make sure everything is written properly and perform a site check before creating the plans. After that, we go to the city or county and take care of the permit. This process usually takes three to six days from the time you sign the paperwork. As soon as we hear back about the permit, we can start installing your solar system.

Chris Zepponi: Good Energy

By James Florence, Diamond Certified Resource Reporter

CONCORD — With a background in sales and marketing, Chris Zepponi has done everything from home loan refinancing to high-tech recruitment. However, it wasn’t until he entered the home improvement field that he discovered the kind of energy that truly suited his personality. “Honestly, I never expected to be in home improvement, but given the economy in 2002, I was happy to get any work I could find,” he recounts. “To my surprise, I fell in love with the industry. In particular, I appreciated the unique opportunity to help people make their dreams come true.”

Chris explains how his involvement in home improvement naturally led to an emphasis on solar energy: “When I first started in this industry, solar wasn’t at the forefront—it was more about general remodeling measures like replacing windows and kitchen cabinets. Within about seven years, however, solar had emerged as a huge aspect, which prompted our company to alter its focus and change its name to High Definition Solar. Today, solar is a cornerstone of the home improvement field, and it continues to grow and evolve.”

As a resident of Fairfield, Chris says he appreciates the energy (both solar and communal) to be found in the Bay Area. “With the exception of maybe New York, I think the Bay Area has the best, most vibrant level of energy in the country. In addition to the people, there are so many opportunities here, especially since Silicon Valley is the high-tech capital of the world. Also, from a solar standpoint, the Bay Area has some of the best climate in the world for solar energy.”

Outside of work, Chris likes to stay active. “I have a passion for working out, so I spend a lot of time at the gym, as well as running and hiking,” he affirms. “I also love playing golf—I could play four or five times a month, no problem.” Chris also enjoys spending quality time with his 15-year-old daughter, Christina. “I like hanging out with my daughter, whether helping her with homework or taking her to the movies.”

In his life and career, Chris says attitude is everything. “If you don’t have a good attitude, you’ll never get to where you want to be in life. When you look at all the top business people and professional athletes, you’ll see they have an attitude that’s second to none. Nothing is going to stop them from being the best, and that’s a mentality we try to emulate at High Definition Solar.”

When asked the first thing he’d do if he were to retire tomorrow, Chris says he’d see the world. “I don’t get to travel as much as I’d like to, so that would probably be number one. I’ve never been to Europe, and since my ethnicity is Greek and Italian, I’d love to visit those countries.”

  • Solar Power and Rate Increase Resistance

    CONCORD — Everyone knows there are benefits to switching to solar energy, but there’s one advantage you may not have considered. One of the great things about going solar is it allows you to lock in your energy rate, which makes you rate increase-resistant against future inflation.

    Since the 1970s, energy rates have gone up by an average of 7 percent each year, and many experts are predicting the rates we currently pay will double or even triple in the coming years. For those who are considered high utility users, those effects are going to compound even more.

    Imagine it’s the 1970s and you’re given the opportunity to lock yourself into a gas price of $.50 a gallon. Over the next four decades, this price increase resistance would’ve allowed you to save thousands of dollars at the pump. When you switch to solar, you’re doing the same thing, only in regard to energy costs. You’re locking in your rate for a lifetime, so when the costs inevitably go up, you won’t feel the pinch like everyone else.

    After you’ve made the switch to solar energy, you may feel a temptation to be more lax about your usage due to the drastically reduced costs. However, since energy remains a vital resource, it’s best to avoid using more energy than you need. Retaining a conscientious mindset after the fact will preserve energy and enable you to make the most of your financial savings.

  • Video: Becoming Rate Increase-Resistant with Solar

    Complete Video Transcription:

    CONCORD — Host, Sarah Rutan: Everyone knows about the benefits of switching to solar energy, but there’s one advantage you may not have considered. Today we’re in Concord with Diamond Certified Expert Contributor Chris Zepponi of High Definition Solar to learn more.

    Diamond Certified Expert Contributor, Chris Zepponi: One of the great things about going solar is you’re making yourself rate increase-resistant, and you’re hedging against inflation. Utility companies are going to continue to raise rates in the future. Since the ’70s, rates have gone up by an average of seven percent. A lot of energy forecasters and experts are predicting that whatever we’re paying now, the rates are going to double to triple, and if you find yourself to be a high PG&E and a high utility user, those effects are going to compound even more. One of the great things about solar is you’re attacking the areas that are doing damage on your bill. If I were to ask you, let’s say, in the ’70s, if you were able to lock yourself into a gallon of gas for 50 cents a gallon, would that have been a wise decision if you had a lifetime contract? The answer of course is yes. That would have saved you thousands and thousands of dollars in terms of money that would have been spent at the pump otherwise.

    You are doing the same exact thing by going solar. You are saving money on your utility bill. Solar’s designed to produce a certain – depending on the size of the solar system, it’s going to produce a certain amount of energy, and the best tip I can give is make sure when you do go solar, don’t use more energy than what you’re using right now. A lot of mistakes are made where just because we’ve gone solar, now we can start turning on all our electrical devices, the TV, and now we’re paying even more money. You don’t want to go down that road. Be energy conscientious. This will have more of an impact on your PG&E bill when you do go solar.

Solar panel quality is great. They were great help on the install, but the billing is confusing. I have to submit the bill to the lender and a couple other places. It's a huge deal on getting them paid. It's really hard to even figure out if they were paid or not. Otherwise, it was good.
