"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

"The last was a rental company that we have and we used them for an air conditioning and heating system. It was Bototach Mechanical. It’s been a good program for us. They’re very responsive. I don’t know what the thought process was. My husband said, well let’s try these guys and so we did. We have an older home and it’s proved to be a very good deal. The quality has been pretty good, so I would give them an A for the quality. I will give you one helpful hint though. If the company decides they want to replace an appliance, you need to call them and negotiate with them because you can upgrade, but you need to talk to them in person not just do it over the internet."

Solar Panels FAQs, answered by experts

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.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
