• How long do solar panels last?

Solar panels are designed to last over 40 years. The panels must be still effective at 80% after 20 years and nearly 50% after 40 years. Most installations on the roofs do not need much maintenance.

• How does it work?

A solar panel, which is known as a photovoltaic (PV) module or panel is composed of solar cells (solar cells). The light energy (photons) hits the solar cells, movement of free electrons located in the structure of silicon. The energy output of PV module is a direct current (DC) which passes through an inverter to convert DC into alternating current (AC). If a system is designed off-grid, solar panels would be connected to a battery bank, then the inverter.

• How much energy can a plant produce?

The total energy produced in a system depends on system size, location and orientation of your home or company, the angle of your roof, and the type of drive you use. A typical 10 kW system located in Windsor (Ontario, Canada) with an angle and optimum orientation will create approximately 14.9 MWh per year.

• Does the winter and snow are a problem for the panels?

The panels can actually produce more energy during cold sunny days than during the summer because they are less effective in hot weather. The panels are mostly around 16 degrees Celsius warmer than the outside temperature. Most of the snow that accumulates on the panels will melt. Solar panels help protect your roof against damage; therefore, a solar installation can increase the longevity of the roof.

• Why go solar?

Solar energy is a clean and renewable energy that works as an alternative to power plants burning fossil fuels, emitting greenhouse gases (CO2), which are responsible for global warming. Today, people try to commit to a healthy environment and become aware of their planet.

• Can I install the system myself?

Yes you can, if you have some experience in construction and electricity.
