    I was promised to have my instalation done in Dec 2021, and didn't happen until mid Jan 2022 for starters, I should have known this was a sign of things to come ! So eventually they were set up for a date in Jan... after staying home all day, at 4:00 in the afternoon I called to inquire when they planned on arriving? I was told , "oh .... the installers are still at a previous job and can't make it . I wasn't thrilled about wasting an entire day ! They showed up the following day to do the installation. During that time, one of their installers decided to take the work van and drive all over my back yard driving repeatedly over my septic system. (Still waiting to find out if any damage was done to septic system. Then the installer got work van stuck in my back yard just before going over a 20 foot cliff !! And had to leave van stuck over night until their return visit the following day, they had a couple things to finish the next day and would only take 1 maybe 2 hours to complete. Well, the following day, they returned early to finish the 2 hours work. I had to jump start the stuck truck for the 3rd or 4th time at this point for the installers , and use my personal truck to pull the van out of my back yard .. After working on the install all day not 1 or 2 hrs, they left knowing the system was not working in any way,as they left ? I had to listen to the solar unit outside beeping 24 hrs a day in Alarm mode .! That was close to 3 months ago at this point !!! I've made repeated calls inquiring when someone was going to come out to finish the installation? ALWAYS told , I'll look into this immediately and get back to you .. It's been1 month since my last inquiry and Still haven't heard a word !? I decided to write my contact person for this company a couple days ago Again inquiring when can I expect someone to call or fix this install ...? 3 days later at this point and of course , NOTHING !? The usual nonresponse . I have a huge hole in the drywall in master bedroom still un repaired, I haven't had lights in my basement working since the "installation " because they were supposed to work off of solar panel system witch has NEVER worked. So no lights or power in my basement, no power to my refrigerator since early January tomorrow is April ! At this point I'm going to have to contact an attorney to get out of this deal with what appears to me , to be a very confused shady company! I also told them if they cannot respond to my emails or calls, I will remove all of their equipment from my home and rewire the basement and refrigerator circuit so they will again work as they did before Design 1 Solar Group came to my home and will have it all stacked at the end of my driveway ! It can sit there for a year for all I care at this point . I would Strongly advise you DO NOT by any means use this joke of a company !

    Panels installed so there was minimal distance to run connections to the meter.  The panels on the left are in shadow by 1:30PM.

    If you're looking for a home solar system, I cannot recommend Cosmo Solaris highly enough. We used…read moreEnergy Sage to help us gather quotes and figure out how to analyze them on an apples-to-apples basis. My wife and I initially wanted to just partially replace our grid purchased electrical energy to help reduce our carbon footprint. But when we ran the numbers over a 15-year time frame, it didn't make financial sense for us. Knowing that energy costs will just keep going up, the cost of a smaller, partial system wasn't viable. We went back to the two best quotes that we had received and spoke with their sales reps. Hassan at Cosmo Solaris was just awesome. We asked him, how close to 100% energy replacement can you get us for no more than "X" number of dollars? We asked the other company the same question and gave them the same cost limit. Hassan came back with a proposal for 100% replacement at our budget--18.9 kW system with guaranteed 26,600 KWh annual production minimum. the other company's answer was 78%. I'm a retired engineer so I dug deep into Cosmo Solaris' quote and examined the engineering documents and researched the parts they proposed (panels, rails/mounts, microinverters, etc.). Their proposal did not cut any corners; everything was top of the line. Cosmo Solaris included purchasing a 3rd party 30-year warranty insurance on every part and the labor for the whole system. Other companies touted their own warranty and the various parts manufacturer's warranties. Well, I know from hard experience, a warranty is only good for as long as that company remains in business. With Cosmo Solaris offering a 3rd party warranty from an insurance company, if anything goes wrong for the next 30 years and Cosmo Solaris or any of the various parts manufacturers go out of business, we're still fully covered, the insurance will pay for equivalent parts and pay for labor. Awesome peace of mind. After signing the contract, Cosmo Solaris earned top marks for communication (thank you Martin!) and making good on all promises. The system was installed on time (actually finished a little early), inspection went smoothly because everything was done correctly, and when we got final approval from our grid provider, my wife and I threw the switch together to go live! Energy Sage helped us evaluate the financial side very well, in our case our breakeven will be in about six years (due to the unusually high cost of energy where we live) since we purchased outright and thus no interest to pay. Yes, there is Present Cost of Money and Lost Opportunity cost if you go that deep, however that is all more than offset by the 30% Federal Tax rebate and the state credits (SRECs-which Cosmo Solaris guaranteed for 15 years). An advisor at Energy Sage compared our system to buying a six-year annuity, once we're past that six-year breakeven point our Cosmo Solaris system will pay thousands of dollars every year in "dividends" providing free energy for 30+ years! Thank you, Cosmo Solaris and Energy Sage.
