The cost can vary based on the size of the solar system, the type of equipment used, the configuration of your roof, and if you purchased through an installer or an sales organization. Make sure you purchase through a real local installer.

Solar panels could reduce your bills to almost nothing, but depending on your ‘load’, how big a system you can install and how much sun your location receives. Some users with ample systems and storage could in fact be paying no electricity bill at all.

Photovoltaic panels have a typical service life of 25 to 30 years. Many manufacturers give a guarantee of their panels’ guaranteed performance over that timescale. But panels can continue to generate electricity longer.

Although they work best in direct sunlight, solar panels can still produce electricity on overcast days, but with less efficiency. Generally speaking, solar panels are long-lasting and made to endure wind, rain, and snow.

Getting connected to the grid entails going through some paperwork (and entering into a grid connection agreement) with your local utility company, probably arranged for you by your installer to make sure you conform to the technological and regulatory requirements.
