"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"While I was very pleased with the design and installation process, the post-installation service is not responsive. One day after going live, the new Franklin WH battery system that was recommended started causing issues with production. They have been out twice to work on it, but only after multiple contacts and pleading. Currently, I have a $24K battery system I had to power down just to keep the solar system going. Unfortunately, they recommended (and I agreed) to install this cutting edge solution based on faulty manufacturer advice. Supposedly it is compatible with Enphase but in reality it is not, so it is not not their fault. I just wish there was as much energy put into getting the system operational as there seems to be with getting the system installed."

"Jason and Allen were great to work with. They had to wrestle with our 30 year old water heater and replace it with a nice new one. They arrived on time in a snow storm and finished hours ahead my expected time frame. I was waiting to hear a list of excuses and expensive problems. However everything was positive and informative. The guys were friendly and prepared. The cost estimate was exactly what the bill was. Plus I learned more about my house which was a great bonus."

Unfortunately, we no longer accept requests through Angi or Homeadvisor due to the number of fake contacts we have received. So, if you would like to contact us here at GRID, you must do so directly through our website or phone. If you would like more information, you can either call or text our toll free number 833-474-3552, or visit our website www.GRIDSOLARLLC.com\n\nWe are a locally owned and operated solar company. We have seen the gimmicks and scams the big companies have been using and decided educate people about how solar REALLY works. We sell fewer systems because of how we operate, but we're okay with that because we do it the right way. \n\nThanks!

"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show.  They were extremely friendly over the phone.  I called at approx 8AM and said they'd be able to come out by 11AM.  They called at about 9:30 to say someone was available to come out now and I said that was perfect.  They arrived at 10AM.

Jason was the plumber who arrived and he was very very friendly and professional.  I told him the problem and we discussed pricing up front.  I had a coupon which he said they would definitely honor.  He immediately got to work.  He wore footies over his shoes while in the house.  He worked diligently and answered all of my questions.  After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.

A very pleasant and hassle free experience.  I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.

The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."

Solar Panels questions, answered by experts

For most U.S. homeowners, switching to solar energy is an excellent investment. A properly sized solar array can significantly reduce your electric bill, saving money on utilities every month. Most homeowners enjoy savings that cover the cost of their solar systems within 12 years and then turn a profit. Additionally, federal and state tax incentives are available that help make solar an even better and more profitable investment.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

The average cost to install solar panels is around $27,000, with most homeowners paying between $4,500 and $54,000. These prices don’t consider the federal investment tax credit (ITC), which can reduce costs by up to 30%. The final price depends on several factors, including the size of the system needed to offset your energy consumption, the amount of sunlight your home receives, your geographical location, the type and brand of panels, labor costs, and any add-on products like solar batteries or electric vehicle (EV) chargers. It is recommended to get price quotes from at least three solar companies in your area to find the best deal.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional—especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn’t require utility services.
