"These people are competent but their ethics are highly questionable. I posted a job description on yelp and tendered offers from many plumbers John's Plumbing replied and agreed to do the work for a specified price. The work consisted of two parts. After they had done the first, they told me it was best to wait until the bathroom wall was tiled before doing the second and assured me they would return. After tiling was complete and I requested they come and finish the work they surprisingly told me it would cost another $500. Miscommunications can of course occur but in this case the scope of work was given to them in detail and clearly included both parts. This is not only highly unprofessional but outright dishonest. While they may be competent I would advise people to consider choosing another company for their plumbing needs that has a higher ethical standard."

Solar Panels questions, answered by experts

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

Correctly installed solar panels will increase the value of your home by around 4%. With the median home sale set at $429,000, this means an increase of approximately $17,000. Many home buyers want to switch to solar, making homes that have this feature tempting and worth the investment compared to homes that are only tied to the grid. Other solar features, like a shed with solar panels, will also boost your home’s value.

Removing solar panels can be straightforward, but it’s not necessarily a simple process. Your contractor needs to prevent damage—not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you’ll need to hire a licensed electrician to disconnect it.

Yes, you should tell your home insurance company about your solar panels. Even if you believe they’re covered by your existing policy, installing a solar panel system is a significant change to your home. This can affect coverage and premiums. By discussing your new solar panel installation with your insurance provider, you can be sure you have enough coverage and that the policy completely covers the panels against 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.
