Frequently asked questions.

What is solar energy?

Solar energy is energy from the sun that is converted into thermal or electrical energy. It is a renewable source of energy that can be harnessed through various technologies, such as photovoltaic (PV) cells that convert sunlight directly into electricity.

How does a solar panel system work?

Solar panels work by absorbing sunlight with photovoltaic cells, generating direct current (DC) energy, and then converting it to usable alternating current (AC) energy with the help of an inverter. This energy is then used to power your home or business.

What are the benefits of solar energy?

Solar energy can help you level out your electricity bills, reduce your carbon footprint, increase property value, and achieve energy independence.

How much can I save by installing solar panels?

The amount you can save depends on several factors, including your electricity usage, your solar panel system size, the angle and orientation of your roof, and local electricity rates. Our solar consultants can help you estimate your potential savings.

Do solar panels work when it's cloudy or rainy?

Yes, solar panels can still produce electricity when it's cloudy or rainy. While their output is reduced in such conditions, modern solar panels are designed to be effective even in less than ideal weather.

What happens to solar panels at night?

Solar panels require sunlight to produce electricity, so they do not generate power at night. However, any excess energy produced during the day can be stored in a battery system for use during the night or during power outages

Do I still receive an electric bill if I have solar panels?

Yes, most solar homeowners will still receive a small electric bill from their utility. This is because most homes remain connected to the grid, using electricity from the utility when the solar panels are not producing enough electricity.

How long do solar panels last?

Most modern solar panels are expected to last at least 25-30 years. However, the efficiency of solar panels decreases slightly over time. Most solar manufacturers guarantee around 80% performance after 25 years.

What maintenance do solar panels require?

Solar panels generally require little to no maintenance. However, it's a good idea to inspect them regularly for any dirt or debris that could block sunlight. If your panels are tilted, rainfall will generally keep them clean.

Can I install solar panels myself?

It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.

What is Net Metering?

Net metering is a billing arrangement that allows solar panel owners to sell excess electricity back to the utility company. When your solar panels produce more electricity than you need, that energy is sent back to the grid in exchange for credits. These credits can be used to draw from the grid when your system is not producing enough electricity, such as during the night or on cloudy days.

What is levelizing costs?

Levelizing costs refers to the process of averaging the total cost of installing and operating a solar system over its expected lifespan to calculate a consistent cost per kilowatt-hour (kWh). This allows for a more accurate comparison with other electricity sources and takes into account all costs including installation, maintenance, the cost of financing, and system lifespan. Levelized cost of electricity (LCOE) is a common measure used in the solar industry to compare the cost of different energy technologies.

What is a smart panel?

A smart panel, also known as a smart solar panel or smart module, is a solar panel equipped with technology that allows for more advanced functionality compared to traditional solar panels. This can include integrated microinverters (which convert the DC electricity produced by the panel into AC electricity at the panel level), module-level power electronics (MLPE) for optimized output, and monitoring systems for real-time performance tracking. These advancements can increase efficiency, provide more detailed data, and improve safety.
