"We are very pleased with the solar panels, battery and energy system installed by Lumina Solar. Their sales pitch was informative, more than pressure sales. We discussed options available for solar and we selected Lumina Solar after considering two other companies. All of their team members were professional and thorough. We even experienced a small problem with our installation and their CEO stepped in to make things right, without hesitation. We highly recommend Lumina Solar to anyone who is actively looking to install solar panels for their home."

"Very well; the garbage disposal that was already installed was a bit unusual of a configuration, so he had to do some extra work. If not for that, the total cost would have been even less. (And, after getting a couple of other quotes just for the garbage disposal, not including the necessary modifications, his total price was still a bit less.)"

Solar Panels questions, answered by experts

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 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.

The time it takes to install solar panels depends on the number of panels and the size of your home, but installation takes between two and three days of work. While most contractors can install the panels over the course of a couple of days, switching to solar energy can take two to three months in total. This includes the time it takes to design the system, procure the parts, obtain the permits, install the panels, connect to the main power grid, and get an inspection.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

The morning sun can be better for solar panels because it’s often brighter and clearer than the afternoon sun. The brighter the sun, the more energy solar panels produce. The strongest rays occur during midday, which tends to be prime time for solar energy generation. Most homes get a mix of morning and afternoon sunlight.
