While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional—especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn’t require utility services.

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

Solar shingles typically last between 20 and 30 years, a lifespan comparable to that of traditional solar panels and standard asphalt shingles. The exact duration depends on the manufacturer and the quality of the installation. Because solar shingles are a newer technology, there is limited data on their actual long-term performance. Factors that can impact their durability and longevity include weather conditions, roof ventilation, and regular maintenance. To extend the life of your solar shingles, you should conduct regular inspections and cleaning, and make any necessary repairs as quickly as possible.

You shouldn’t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.
