A cleaner, more sustainable energy
future isn’t an unattainable dream. Solar power can help it become a
reality.
Numerous advantages of solar energy
are making more homeowners interested in using it to meet their energy needs.
This guide lays out the fundamentals of solar energy. We’ll answer the most
common questions we hear and provide you with the knowledge you need to embark
on a solar-powered journey.
And, don’t worry. It will be
environmentally friendly AND financially savvy.
How Do Solar Panels Work?
Solar panels, also known as
photovoltaic (PV) panels, are the vehicles that make solar energy solutions
work. These panels convert sunlight directly into electricity through a process
called the photovoltaic effect.
Each solar panel is composed of
numerous solar cells, typically made from silicon, which absorb particles of
light (photons) from the sun. When these photons are absorbed, they release
electrons from the atoms within the solar cells, generating an electric
current. This current is then captured and saved to power various energy needs.
This electricity can be used to power
your home, which reduces your reliance on traditional grid-supplied electricity
and lowers your energy bills.
Solar Panel Size
One common question homeowners ask
about is the size of solar panels. What size do they need? They can vary, but
the most commonly used residential solar panels are around 65 inches by 39
inches. However, the power output of a solar panel is more crucial than its
physical size. This power output is measured in watts (W) and can range from
about 250W to over 400W per panel.
The number of panels you'll need
depends on your energy consumption and the amount of sunlight your home or
business receives. You need to consider your available roof space when you’re
trying to decide on solar panel sizes. A professional solar installer can help
you determine the optimal panel size and quantity based on your energy goals
and roof dimensions.
Best Battery Chemistry for
Solar
Solar panels are most effective when
the sun is shining, but what about cloudy days or at night? These times are
when energy storage comes into play. Batteries can store excess energy
generated during the day to use during less sunny periods. The choice of
battery chemistry is crucial for long-term performance and safety.
As far as the best battery chemistry
for your solar system goes, lithium-ion batteries are a popular choice. They
offer high energy density, efficiency, and a relatively long lifespan. These
batteries can power your home during the evening and even during power outages,
providing you with a continuous and reliable source of electricity.
