Answering Your Most Frequently Asked Questions About Solar Panels

When it comes to adopting solar energy, it's natural to have many questions. From the installation process to long-term maintenance, understanding how solar panels work can be key to making informed decisions. Here we present clear answers to some of the most common questions about solar panels:

How long do solar panels last? Solar panels are designed to last for decades. Most manufacturers offer performance warranties of at least 25 years, which means that even after this period, the panels will continue to generate power, albeit perhaps at a slightly reduced rate.

How much space do I need to install solar panels on my home? The amount of space needed depends on several factors, including the efficiency of the solar panels and the amount of energy you want to generate. In general, it is recommended to have at least 100 square feet of roof space per kilowatt of installed solar power.

What happens on cloudy or rainy days? Although solar energy production may decrease on cloudy or rainy days, solar panels can still generate electricity. Even under diffuse light conditions, panels can capture enough solar energy to keep your home's electrical systems running.

Do I need batteries to store solar energy? While storage batteries can be a useful addition to maximize your home's energy self-sufficiency, they are not necessary for all solar systems. Many homes are connected to the electrical grid and can use it as a "virtual warehouse" for their excess solar energy through net metering.

How can I finance the installation of solar panels? There are several financing options available, including solar loans, leases, and power purchase agreements (PPAs). Additionally, in many places, there are tax incentives and subsidy programs available to help reduce the initial cost of installation.

We hope these answers help you better understand how solar panels work and how they can benefit your home or business.
