"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

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

A few disadvantages of installing solar panels on your roof include the high up-front costs and the potential for increased property taxes. Installing solar panels can increase the home’s value, which in turn can mean higher taxes. Depending on your area, you should check with your local tax offices for more information. Another potential pitfall is roof leaks from a poor installation, but this shouldn’t be an issue if you hire a reputable company.

The best way to save money on solar panels is to take advantage of federal and state solar incentives. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total—if you can take the entire credit, which is based on income taxes owed—or an average of around $9,000. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.

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.
