"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"Patrick was so thorough in his analysis and then presentation for my home. With my home being a new construction, and without any electric bills to evaluate possible savings going solar, he went the extra mile to obtain info of surrounding homes and their power usage. Patrick will walk away from a deal that he does not think is right for you. If you are thinking of going solar, Patrick is the person you need to talk to."

Solar Panels questions, answered by experts

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.

The best solar panels to withstand hail are those rated UL 61730. These solar panels are certified to withstand hailstones up to 3 inches in diameter and travel at speeds up to 88 mph. IP68 solar panels are the next most resilient solar panel. Solar panels without these ratings can handle hail up to 1 inch in diameter that travels up to 50 miles per hour. If you live in an area with frequent or severe hailstorms, purchasing UL 61730 solar panels is often worth the investment.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.
