"I had 25 LG solar panels installed by Sunpro this year and they did a fantastic job. The communication was great and the install crew was very professional. It's been awesome watching our electric bill go down!"

"At first I was skeptical about getting solar panels. I thought it would be too much trouble and not worth the time. I was wrong!! After talking with Nick Zink we had our panels installed and 6 months later we have seen amazing savings on our power bill. I also cannot say how amazing Nick has been. He walked us through and ensured every concern or worry was resolved before the install and personally walked through the process and checked to ensure everything was done on time. The installation went seamlessly and ahead of time, they cleaned thoroughly afterwards, and the respect they showed was incredible. If you get solar panels ask for Nick Zink. I trust no one else."

"

Everyone I worked with was very knowledgeable and willingly shared information with me. The engineer, Andrew, responded to my calls and questions quickly and kept me informed of what to expect along the way. Permits and coordination with the electric company were all handled by Sustainable Energy Solutions - I didn't have to worry about a thing. The installation crew, Adam, Eric, and Greg, were on time each day, professional, and very courteous and friendly. When they encountered a problem identifying the location of the patio roof trusses, they presented it to me with a solution. Dan the electrician patiently explained how the meters and my tie-in with the electric company worked. It was such a thrill to flip the switch on my beautiful new solar system and start producing my own clean energy!

"The only time I get upset with Dish is when there is a storm I lose picture for a little while because the dish gets clogged. I really like them and I would recommend them.  They are polite and they try to solve your problem over the phone so you don’t have people coming to your house all the time. I get about 200 channels."

Solar Panels questions, answered by experts

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.
