Solar panels are not created equal. Here are some good questions to ask to understand what is being proposed so you can find the right panel for your home or business.

Here’s what you should understand regarding the difference in solar panels when you’re considering solar.

Efficiency

What’s the efficiency? That is, how efficient is each panel in converting light to electricity? The higher the efficiency the more electricity each panel will make. The more each panel makes, the fewer panels you will need on your roof. Currently, SunPower panels are the most efficient panels made, and Renova Energy is a certified retailer of SunPower panels in the Coachella Valley.

Warranty

What about the warranty? With SunPower, you get a 25-year comprehensive warranty for parts and labor. And because their panels (if they are AC) have the inverter built into each panel, that part receives a 25-year warranty as well. If your installer is suggesting a DC panel, that means there’s a separate inverter or two that will likely only have 10-year warranties.

Degradation

What is the rate of degradation? Every panel will lose a little bit of efficiency each year, but with SunPower the rate of degradation is slower than every other panel on the market. In fact, after 25 years, each panel is guaranteed to still be producing 92% or more of its original production.

Reliability

Where is the solar company headquartered and how long have they been in the solar business? If there’s ever an issue with the panels and your installer can’t be reached, you need to make sure you can follow up with the panel manufacturer to handle any warranty issues.

Also, some companies have “jumped” into the solar or battery storage business but can just as easily “jump” out. SunPower has been a solar panel manufacturer for more than 30 years and has more than 800 solar patents. They’ve built a solid reputation for reliable solar products and customer service.
