Solar panels have changed the renewable energy industry in more ways than ever thought possible. Fully utilizing clean energy, as opposed to burning fossil fuels, has enabled homeowners, business owners, and corporations alike to reduce their carbon footprint and lock in their electricity rates once and for all. But how did we get to where we are today? Solar technology itself is not a new concept. It has slowly evolved as technology has advanced. Evidence dates back as far as the 7th century, but it wasn’t until the last century that the first photovoltaic cells were produced, which make up modern solar systems. Learn more about the history of solar here.

Photovoltaics (PV) or solar cells convert sunlight into direct current (DC) electricity. DC electricity is a uni-directional current, so the flow of charge is always in the same direction. PV systems then invert the DC electricity to alternating current (AC) electricity which is what is compatible with the appliances we use in our homes and is interconnected to the larger grid. AC electricity is an electric current that periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC), which flows only in one direction

Since the 1980s, photovoltaics have been a common power source for consumer electronic devices and have grown to make up rooftop solar systems capable of powering homes and buildings. Today, solar power is more affordable than ever before. As technology, science, and manufacturing continue to advance, this makes it easier and cheaper to make the switch to solar power. With a vast number of financial incentives, aid, and rebates available, the choice to switch to solar becomes reasonably simple. Combining this with the long-term savings and locked-in energy rates, solar PV systems are a smart investment.

If you think you’re ready to install a rooftop solar PV system, here are a few questions to ask yourself:

  • Do you own or rent your home?
  • How long will you live in this home?
  • How much energy do you consume?
  • Is your house positioned in direct sunlight?
  • What is your budget for the project?

There are solar options available for everyone, regardless of the answer to any of these questions, but there are a few things to consider for a rooftop solar PV system for your home. If you rent rather than owning your home, you’ll have to receive approval from the property owner before installing solar panels. For solar to be a valuable investment, it is best if you’re planning to live in your home long-term (7-15 years), although solar systems have been proven to increase your home’s value should you choose to sell. Other factors like your energy usage, roof positioning, and budget can all be evaluated with a solar expert to determine your solar readiness.
