Solar Panel Installation reviews in Rockville

    Solar Energy Services Inc
    I have used Solar Energy Services since they first installed my system. I have had them perform an overall review several times. Most recently I had one of the collectors on the roof spring a leak and of course called Solar Energy Services. They immediately dispatched a senior manager in the company to perform an overall review of my system so that they could inform me exactly what I needed. The visit was then followed up quickly by a technician to perform the repairs. His attention to detail and explanation for what he was doing, how to optimize my system and even checked some of the pool settings to ensure I was getting the most capability from the Solar System. I highly recommend this company and cannot say enough good things about their response, their office personnel, and the field technician. It was a pleasure doing business with them.

    Standard Energy Solutions
    The superb repair tech that usually does this work was injured and therefore not available. As a result we had to wait some weeks to be fit into the installation crew schedule. The work was excellent and was performed when promised.

    Maryland Solar Solutions Inc
    This is an outstanding company, with flawless communications, first-rate workmanship, and state-of-the-art equipment installed. Yes it costs more than others, but I tried to work with one other company and despite good reviews, they were terribly unreliable in every way. So, I suppose I got what I paid for. Technicians took the time to make the system cosmetically clean--all wiring dressed, placed as inconspicuously as possible. This was a stress-free project, and I feel lucky to have found MSSI. They have a 1-page contract--no small print. The warranty is rock solid, and there is terrific support from the office whenever I call. One of the most responsive companies I've ever done business with. There's a reason MSSI has a perfect record of EXCELLENT reviews from customers. Yeah, I know, this review sounds suspiciously over-the-top. I'm genuinely quite happy with the way this worked out, and can't say enough to recommend them.

    Direct Energy Solar
    Have been waiting for months to have several failed microinverters replaced (a continual issue with the Enphase M190's). Direct Energy Solar does not answer emails. They do not answer the phone (unless you are calling to install a new array).

    I got a lot of help from them and they pointed out to me at the right direction. They were really good because they crawled into the attic and took a couple of photographs to show exactly where the water was coming in. They showed it was not their installation and it was the skylight that was there. They were really nice. They were right back here the next morning. I called them late afternoon. Three guys came out and crawled to the top of the roof, then up in the attic and started searching. They did a nice job. They showed me from where it was coming, so I already knew where it was. They don't do roofing work and they were inspecting their work. They were real professionals and across the board doing the installation. They weren't responsible, but just came to double check. They have an excellent program too. I pay for the electricity I get and they own the panels. I don't have to shell out $50000 or things like that. I am paying a $0.08 kW. They own it and I just pay for the electricity. I just pay for the power they produce. It is cheaper than what the electrical companies charge me. If it is really nice, bright and sunny and I am not using the a/c, then my meter runs backward. I am happy. If I move and get into another house then I will definitely use them again.

    Aurora Energy, Inc.
    Mike Ryan was my main contact at the company.  He met with us initially and then through a thorough iterative process, he designed the system.  Mike and the company were very professional throughout.  And, what was very impressive was that during the design process i had found a component that improved the performance of the system.  When i gave the information to Mike he did his homework and came back with an enthusiastic approval to add the component to the system.  The installation work was done on time, very professionally.  The install is very neat and clean.  We are very pleased.

    Everything looked good except for the finances.  The pricing was presented without any basis.  When I questioned it, suddenly the price was reduced by 1/3, still without any basis.  I was left feeling that I had no idea whether the price was fair--in fact, suspecting that an even better price might be available.
    The savings from solar were not as high as I expected.  I never received a good explanation of the financial side of the deal.

    Maryland Solar Solutions Inc
    I conducted a nearly three year review of solar companies, alternatives, etc.  I met with 9 different solar companies (3 of which are no longer in business).  I compared leasing to buying.  Leasing was not for me because in addition to reducing my carbon footprint, I wanted the greater savings and tax benefits you get from purchasing a system. 

    I selected Maryland Solar Solutions, Inc (MSSI) to handle my solar installation.  I KNOW I chose the best company!  I signed the contract and the design, permitting, installation and inspections were completed in 37 days!  My net meter from PEPCO was installed one week later.   This was extraordinarily fast ... not something that was anticipated but sure am happy it was that fast!
    What makes MSSI stand out from the rest is they are as interested in the success of your individual system as you are.  It is a small, woman-owned Maryland company.  The owner, Colette Hayward, was present from the initial meeting and throughout the installation where she was totally hands-on, working side-by-side with her employees installing the panels, wiring the boxes along with the electricians, checking the condition of the panels when they were delivered, and doing the walk-throughs during each county inspection.  She was one of the first in this area to get her certification -- only now are many companies getting someone certified because now it is required.  Colette did it because she felt it was important ... and did it long before it was required. She was one of only three contractors that went on my roof during our initial meeting, where she took several readings to see what system would work best and estimate the output to provide an educated guess regarding length of time until the system would pay for itself.  She was the ONLY contractor who went into my attic space (not an actual attic but the kind you crawl through) to see what the support construction is and if there were any "surprises".  (While up there she discovered a serious electrical hazard that could have been disastrous.  I immediately had an electrician correct it!)  Colette was the ONLY contractor who discussed moving vents in my roof, allowing for more panels to be installed and the layout being more aesthetically pleasing.  Colette was also the ONLY contractor who recommended a "critter guard" to protect the wiring of the panels on the roof from being chewed up by squirrels or other critters.  She learned about this the hard way -- when critters chewed up the wires on the solar panels on her own home!  I could go on and on about what a terrific company MSSI is!  They are heads and shoulders better than all of the other companies I met with.  (No, I am NOT related to them.  I found them through Angie's List when looking up reviews of other companies I had met with.)

    I have been making my own electric for two weeks.  For this time period I will be billed only 25% of my home's electric usage.  That is a 75% savings -- and that was with many days of rain and heavy clouds!  Of course this won't be the norm for the entire year, with less daytime hours in the winter, more use of air conditioning in July and Auguest, etc..  But my outdoor pool has been open the entire time so the usage has included running the pool filters 12 hrs a day, the cleaning equipment several hours a day, etc..  It is a great start and a very good sign!  My panels don't have a southern exposure, which would make the panels even more efficient.  I have huge trees that would not allow for that configuration.  Instead the panels are on sloping (not steep) roofs facing east and west.

    If you want to work with a solar contractor that is professional, highly knowledgeable and incredibly trustworthy .... then hire MSSI!  It has been a total pleasure working with them ... and I am thrilled with the job they did for me!  Thank you to the others on Angie's List that said such great (and accurate!) things about Colette Hayward that I just HAD TO have her come discuss my project ... when I thought I had already seen enough companies and was not looking to add another.  I am SURE glad I did!


    One day last week I heard someone on my roof.  I was not expecting anyone so was curious as to who was there and why.  I was not able to get outside -- but happened to see a missed phone call so checked my voice mail.  There was a message from Maryland Solar Solutions, Inc (MSSI) that someone was coming by to clear my solar panels of ice and snow so they would be working at full capacity.  Because the weather forecast was for days and days of below freezing temps, if the panels had not been cleaned off they would be working at much less efficiency for quite a bit of time.

    So I was not just grateful that MSSI did this so I would continue to get the highest value from my solar array, but they did this without my requesting it.  They took it upon themselves to do this wonderful customer service -- and at no cost to me.  This shows you just one of the many differences (benefits!) of using MSSI -- at almost 2 years past my installation they continue to be a leader in customer service!  What an excellent firm to work with!  Thank you, Maryland Solar Solutions, Inc.!  You definitely ARE the best!

    While I dealt mainly with Mike Ryan, who was terrific, absolutely everyone was 100 percent professional at all times. Mike took care of every detail...working with the city, Pepco, and the SREC contract. He made it as easy for me as possible. If you're interested in getting solar panels, I highly recommend Aurora.
