How does solar energy work? 10 benefits of photovoltaic (PV) solar panels

Solar photovoltaic (PV) systems – also called solar panel systems, solar energy systems, or solar power systems – convert light from the sun into usable electricity. This electricity generated by your solar PV system can power your home, your business or even your electric car.

How solar energy works

1. Solar panel systems are a great way for you to save money, no matter what your budget is.

If you can afford to pay your electricity bill every month, you can afford to install a solar panel system. With a $0-down solar loan or solar lease, you can finance your system and see immediate savings.

2. Installing a solar panel system is a great investment.

Investing in a solar PV system can provide better returns than stocks and bonds – and now is the time to make this type of investment. The longer you have a system the greater the returns you will see.

3. Solar photovoltaic systems have been around for a long time.

Solar PV systems are a well-proven technology first invented in 1954 by scientists at Bell Labs. Today, solar panels provide electricity for millions of homes in North America and Central America.

4. Solar panel systems are highly durable.

Solar photovoltaic panels are made of tempered glass and can withstand hail, snow, sand, rain, and high winds. They can even extend the life of your roof by protecting it from daily wear and tear.

5. Solar power systems can produce electricity for 25 or more years.

The best solar PV panel manufacturers like Canadian Solar and Seraphim offer a 25-year power production warranty guaranteeing that their solar panels will continue to generate electricity at a certain capacity for the warranty’s duration. We also offer Peimar solar PV panels that have a 30-year warranty. Here is something to think about… Some of the oldest solar panels manufactured 60 years ago are still working above 90% efficiency. The technology today is superior to what it was just 20 years ago. So it is very possible that solar PV panels manufactured today will last far beyond their power production warranties.

6. Solar power systems are practically maintenance-free.

Solar panel systems are very durable. Usually, they don’t need to be washed or cleaned.

7. Solar panels can be installed almost anywhere in Central America.

Most locations in Central America get more than enough sunlight to produce sufficient electricity from solar panels. Even in areas with many trees or frequently cloudy conditions, you can still benefit greatly from solar panels.

8. Solar energy systems can be tied to the electric grid and at the same time can greatly benefit from batteries to store power.

If you choose to remain connected to the electricity grid (grid-tied) you will never be without electricity. At times when your system produces more electricity than you use, you receive credit for the electricity you send to the grid; if you need more electricity than your solar energy system is producing, you can draw it from the grid. With batteries, more of the electricity you produce stays with you, providing you a reliable backup system as well as saving you and the electricity company money.

9. Solar power systems can eliminate most of your electricity bill or all of it with the right batteries.

With the right planning, your solar panels can generate enough electricity to meet your needs over a 12-month period. As long as you have enough roof space to install the right size solar panel system, the power that your panels will produce will effectively eliminate most of your electricity bill. If you choose to go off-grid you need a battery system and perhaps some wind power to supplement your solar panel system. This can provide you the ultimate freedom in energy power production.

10. Solar PV panels can be installed on the roof of your home or business, on the ground or on a solar canopy or pergola.

Solar panels can be installed almost anywhere that receives direct sunshine for most of the day and is not shaded by too many trees or buildings. Panels that face south will produce the most electricity, but your panels can also face east or west. In Central America, the sun is almost directly above for a good portion of the day so you can benefit even more than those who live in North America.
