Southwest Austin - Dripping Springs Edition - October 2021


We have a new test where we are comparing the performance of these two technologies side by side.” -EH Does HESOLAR install batteries? “Yes, HESOLAR is a certified installer of the Tesla Powerwall. With the Tesla Powerwall, a solar pv system can continue to operate in the event of a power outage. The Powerwalls can be added now or retrofitted to a system in the future without replacing existing equipment. This year we added Tesla Powerwalls to the test array and will continue to make suggestions based on our findings.” -DH What makes HESOLAR different from their competitors? “We have many answers to that question. The most common feedback we get is that our customers value working directly with Derrick and I from start to finish. Customers also have our direct contact after installation. On the sales side, we don’t knock on doors and we don’t push the sell, we just educate. Behind the scenes is where we really differentiate ourselves. Derrick and I have been Master Electricians for over 10 years, and we’re NABCEP Certi- fied Solar Installation Professionals. We lead our team through the design, installation, and warranty of your system. We don’t subcontract our labor and we use the highest quality materials available. Below is a table we use to display the differences between HESOLAR and our competitors.” -EH

Q & A with the Hoffman Brothers

What exactly does HESOLAR Do? “The service we provide is a specialized form of electrical contracting. Derrick and I are second generation Master Electricians that grew up in the electrical industry. We’ve spent the last 10 years building on our skill-sets as Master Electricians specializing in solar power, energy storage, and electric vehicle charging. ” -Eric Hoffman Why are customers adding solar? “Saving money, back-up power capabilities, lowering their carbon footprint, energy independence... Ultimately, solar power allows customers to invest in their own energy needs. The cost of solar installation will be offset by savings gained on their electric bills. Additionally, the current Federal Tax Credit of 26% has motivated a lot of our customers to act now before the credit goes away.” - Derrick Hoffman How does the Tax Credit work? “The credit is factored on the entire system cost. It is currently at 26% and will ramp down to 22% next year. Homeowners should consult with a Tax Professional regarding applicability.” -DH Are all solar panels the same? “Not at all. Solar panels come in different colors, sizes, and quality. That’s why we created the HESOLAR Test Array. We are actively monitoring the top solar panels in the solar industry and specify our material based on the results. We are also testing leading inverter technologies.” -DH

Any advice for homeowners ready to go solar? “Be careful with sales companies knocking on doors and advertising bogus claims on social media like Facebook. Their goal is to get in your house and convince you to make a rush decision. Our advice is to politely close the door. Don’t rush this purchase, take your time and do your research. Craftsmen don’t find you, you find us.” -EH

What are inverters? “The inverter converts the solar panel’s DC voltage to an AC voltage. Solar consumers will have a choice between Microinverters and DC-Optimized String Inverters. Microinverters convert the DC to AC under the solar panel. A DC-Optimized string inverter manipulates the DC voltage under the solar panel and then sends it to an inverter near the electrical service.
