The time has come, to test these two together! Enphase IQ8A Microinverter versus Tigo Power Optimizer + SMA String Inverter! We performed another set of 20+ Tests, with and without shading to determine which one wins the battle! Are they really that different? What is the cost comparison? What do you guys think? Let me know!

Every now and then something unexpectedly amazing happens in one's life.
That is how I feel about the wonderful team a Solartime USA. These people truly understand what customer service is all about. From Jason who spent almost 2 hours in our home going over every detail and answering all questions we had,
Martyna is truly unbelievable. She makes herself available morning noon and night to answer texts and to make sure we are up to date with everything that is going to happen.
Kathy always follows -up with the schedule of events the at least two days before they happen.
Jake and Gene were wonderful during the installation. They mad sure that the crew was on time and the site looked clean at the end of the day. They both had no problem coming out to run another ethernet cable when it was determined that the original one they were using was not any good.
It truly is my pleasure to thank you to such a wonderful organization. You cannot go wrong making Solartime USA you source for a system for our home.

Since I remotely assisted my daughter and her husband with their solar system installation for their house in Oahu, Hawaii, I was curious if I could also benefit from a solar system. I responded to an internet post and received four responses (I had asked for only four). The very first was from Solartime. All four offered to come to my home to give me an analysis and job bid, but I decided to just work with two of them. Solartime's representative met with me at my home in Plano and did a thorough analysis and proposal. In my case, I was looking at a system purchase as an investment. He added to my solar system knowledge by educating me on aspects I had not considered. He was not at all pushy and was very focused on making me a happy customer by specifying components I requested based on what I had learned helping my daughter’s system. He did persuade me to install two central inverters with panel optimizers versus per-panel micro-inverters based on Solartime experience and industry research. I had been leaning toward the micro-inverters because my daughter’s installer recommended them. But Solartime's rep explained they don’t hold up as well in our Texas heat.
He also informed me about a rebate program offered by the City of Plano, producing all required paperwork for me to submit – a fairly detailed process that had to be followed precisely to avoid being disqualified. The result was a $5000 rebate from the City of Plano. He also explained how I will receive a 30% federal income tax credit off this year’s taxes. As a result, my net cost for a high-quality 9.9 KW system will be half of my total cost. In addition, He pointed me to Green Mountain Energy as my electric retail provider since they pay the same amount for electricity my system produces as they charge for their electricity I use. For the two months with solar credits, the savings have been significant. Part of my proposal was an included radiant barrier in my attic. As a result of the 30-panel solar system and the radiant barrier, Solartime projected my total annual electric cost to be virtually zero.
Solartime provided a high-quality permit submission to the City of Plano, which was accepted with no issues. Their installers did an excellent job, which I personally watched because I am retired and wanted to see how it all went together. They also were on hand to meet with the City inspector for the final inspection, answered all his questions and made some minor adjustments, resulting in a passing inspection the first time.
It has been a pleasure working with Solartme’s management and employees. I really like the fact that they are both a local (Richardson) family-owned company but also one that has done many, many installations here and also internationally. And I can personally vouch for them going above and beyond to ensure I am happy with my system.

Solartime USA has been a great company to work with. The company has a courteous, professional staff that present themselves as a company you can have confidence in purchasing from. Each and every individual I encountered was thoughtful in their duties and responsibilities. From initial sales interaction to installation and tech I have been very pleased with their customer service.
After some research, I found the components of our system to be quality materials and manufacturing. This is another reason I went with Solartime USA. I researched the equipment of other companies and the quality, and warranty of SolarTime USA's equipment surpassed that of their competitors.
The city rebate and federal tax credit made the decision even more of a no-brainer.
The bills have been great. I looked up the previous years bill for the month of July and it was $300 some odd dollars. If I remember correctly it was around $325. This year with solar my bill was a deduction from my Green Mountain Energy credit I have been building since March. I still have credit on account with Green Mountain. It was an unusual experience not having to pay for electricity during the heat of summer.

We are truly enjoying our access to solar energy.

I interviewed 3 solar companies and went with Solartime USA because the sales man did not try and sell me something i did not need. All calls are promptly returned usually by one of the owners. Great customer service, Family owned and overall system looks good with a good warranty. System exceeds what i expected.

Very happy with our 14.5 kw system. We got our Plano rebate thanks to Martina and Kathy's help! They have a rebate program for certain homes in Plano. This helped us finance the system. There was no down payment, we just got approved for financing through their company and it has been very easy throughout the process. I cant believe we used to pay $300 a month during summer now that our financing is less than $180, and our bills are less than $10! SO WORTH IT! Plus they truly treat you like family!

Solartime USA is by far the best company that stands out among the other ones in that business. I did spend some good time and I did my due diligence before making the decision of which company to hire for my solar system installation. I talked to 8 of the most popular and highly rated companies in my area and I had 8 different quotes. I was impressed by the professionalism, the product and the personal approach of Solartime USA. Martina and her staff are amazing, caring no rush, friendly people. I spoke with her father Pavel who started the company while ago and he walked me thru all the details, the product specifications, installation timeframe and the warranty, which was the best compared to all 8 companies I was dealing with. They have the best warranty, they don't hire third companies for their installation and their customer service after I installed the system is impressive. I am so happy that I went solar and I am very happy that I did it with Solartime USA. Thank you Pavel, thank you Martina, thank you guys not just for the great service but also for the friendship and for your amazing care for your customers!

Solartime has been a local installer in the great Plano/Richardson area for some time, they know the area and it's solar exposure quite well and can provide very good metrics for what system you will need and what to expect from it. If you are entertaining getting residential solar I would certainly recommend at least getting a quote from them to compare and contrast against what you already have been quoted.

I have been thinking about solar for years and in other homes I have owned. I even looked into it a few times. I had begun looking again when I was approached through Costco about going Solar. I began doing research and decided that the company that approached me was not for me. All companies had looked at felt high pressure, or didn't want to set up the system or where not as open with their responses as I would like. Several of them wanted me to complete a installation contract before getting a quote. I signed one and submitted the cancellation almost immediately as it made me feel like something was not right. Then I found SolarTime USA.
This has actually been a really positive experience. Jason DeFreese was my sales contact and was very open to my questions, prompt with his responses, and I was able to verify everything that he told me about going solar. There was no high pressure tactics and I didn't have to sign a contract to get my quote. I decided to go solar and they handled all of the paperwork. Jason put me into contact with Dora my scheduler and she kept me informed of everything. The installation crew came and I am very particular about my home but they were very courteous, respectful of my home, and did really good work. This has been a great experience and I am very pleased to have gone with SolarTime USA. I hope this will be the same in 5 years, but as of now this has been nothing but an exceptional experience.

We enjoyed working with this company. They did the work as scheduled and were friendly and helpful throughout the process. We are so happy with our new bills.
