Behold the HESOLAR Test Array! Located in the Greater Austin TX area showing how Premium Solar Panels perform in our local environment. Our test array uses module level electronics to actively compare all of the latest solar panels on the market.
The Hoffman brothers are both Master Electricians that grew up in the Austin electrical industry. The brothers make a point to test all new electrical equipment before offering it to their customers.
Panasonic's HIT solar panels are high efficiency and have a proven 40 year manufacturing history.
SunPower's solar panels have a copper backplate that offers a clean aesthetic and high efficiency.
LG NeON 2
LG's NeON2 have 2 options: The 12 bus-bar front contact & the R-Series ultra efficient rear contact.
We also compare solar panels from Solaria, Q-Cells, Mission Solar, and more!
Using SolarEdge DC optimizers we are able to mix different solar panels and log their production. DC optimizers do not clip power output like micro inverters. This gives us full output potential under various Central Texas weather conditions.
All of the original HESOLAR Test Array solar panels were deployed at the same time. Solar power output will slowly degrade from age. This is an important variable that we will take into consideration as we add new panels to the array. (NOTE: We have recently added QCells 325W and Solaria 340 & 350W)
Ranking Factors – Compared Below:
Before you scroll down to the rankings (you already did.. didn’t you!) get to know the factors we take into consideration.
Cost: Cost is rated by the cost per yield (kWh) of each solar panel as recorded on the HESOLAR Test Array. Consumers interested in cost should pay close attention to QCell vs. LG Solar Comparison below. Visit our Solar Panel Cost page to learn more about complete system cost in Austin TX.
Efficiency: Efficiency is rated by the yield per sqft as recorded on the HESOLAR test array. All panels compared below are considered High Efficiency. Consumers curious about the most efficient solar panels on the market can compare SunPower vs LG R Series below.
Product Warranty: It is important that customers learn the difference between product warranty and power guarantee. Product warranty covers various defects. Solar panel defects are incredibly rare for premium solar panel manufacturers. Compare the top solar panel warranties in the industry below by comparing Panasonic vs SunPower Solar. Note: Warranty assumes Panasonic Enhanced Partner and SunPower Partner Status
Performance: Performance is rated by the yield per watt (nameplate rating) of each solar panel on the HESOLAR Test Array. Keep a close eye on the performance results as they are the most important values. We will continue to update the results as these technologies age.
Factors – Not Compared Below:
Weather Conditions: Our values reflect weather conditions for the Greater Austin / San Marcos TX area where the solar panels are located.
Power Guarantee (AKA Performance Warranty): Guarantees power output for a specified amount of time. Power guarantees are difficult to prove without dc-optimizers or micro inverters.
Warranty Reliability: Solar Panel manufacturers are in a highly competitive environment and we have seen numerous bankruptcies over the years. As an installation company, we add value to companies like LG and Panasonic that have a diverse portfolio and can survive solar market fluctuations.
