How Are Solar Panels Designed? (Your Solar System)

June 16, 2022

Sharing is caring!

A solar panel design isn’t as complicated as some property owners might think. In truth, solar panels have no moving parts and need little to no maintenance over the years! In turn, you can enjoy clean, green energy for decades when you invest in a solar array.

However, knowing more about solar panel design can help you better understand what’s needed for them to function. You can then decide if they’re the right investment for your property. Additionally, this information ensures you keep those panels working optimally over the years.

The Basics of Solar Panel Design

A solar power system has three main components. First, the solar panels or modules capture the sun’s rays. Second, inverters change that energy to the type used by most household electronics and appliances. Lastly, a racking system holds those modules or panels in place. Note some added details about each of these components so you know how they operate when it comes to solar panel design.

How do solar panels work?

Solar panels installed on your property use photovoltaic or PV cells. These cells absorb sunlight shining onto those panels. Next, photons or light particles knock electrons free from atoms in that cell. Lastly, this process starts electricity flowing over wires in those cells.

What are solar inverters?

Those PV cells create direct current or DC power. This electricity moves in just one direction. However, most electronics and appliances need alternating current or AC power. Alternating current moves in more than one direction.

To change that DC power to usable AC power, a solar panel system includes an inverter. This inverter takes the energy created by those PV panels and pushes it through a transformer. The transformer forces the DC power into AC power, which is what your standard appliances and electronics use.

What is a solar racking system?

A contractor does not just attach solar panels to a property’s roof. Instead, he or she starts with a solar racking system. This system resembles a bedframe, with metal rails that attach to roof decking. Next, panels attach to those rails or racks.

This racking system is a vital part of your overall solar array. A contractor must angle or tile that system so that those panels get maximum sun exposure. Also, a contractor must properly seal attachment points, to avoid roof damage.

Do Solar Panels Work In Wintertime?

Since solar panels have no moving parts, there is no risk that they’ll “freeze up” during wintertime. Also, note that PV cells capture any sunlight that comes their way. In turn, they will still work to convert sunlight into usable power during winter months.

However, most areas experience far less sunshine during wintertime than they do in summertime. Consequently, solar panels produce less usable energy during wintertime, or any day with reduced sunshine. Also, property owners should keep panels clear of snow so PV cells can capture as much sunshine as possible.

How Do Contractors Design a Solar Power System?

Contractors design solar power systems for every property individually. They consider a property owner’s installation budget and energy needs as well as space available. Also, that contractor needs to install panels for maximum sunlight exposure.

In turn, your solar power system might consist of fewer panels than someone else’s array. As an example, your property’s roof might only have space for a certain number of panels! Additionally, a contractor might not want to install panels where a chimney or other obstruction blocks sun exposure. Above all, they need to consider your installation budget when choosing panels for your property.

On the other hand, a contractor might suggest as many panels as your property can support and your budget allows! Remember that the more panels you install, the more solar power your property produces. Your installer can also offer suggestions for creating a solar system that’s right for your home or business.

The Longevity of Solar Panels

Property owners should note that solar panels rarely just shut down or outright fail. Instead, they lose effectiveness as wires and PV cells degrade due to age and exposure to weather and sunlight. In turn, solar panels don’t capture and convert power as readily the older they get.

Most solar panels lose effectiveness at about 1% annually. In other words, a 10-year-old panel has probably lost about 10% of its efficiency. In turn, it’s only producing about 90% of the solar power a new panel might produce.

Consequently, many property owners plan on replacing their panels after 25, 30, or 35 years. By that time panels typically produce 75% or less energy than new panels produce. Investing in new panels then means enjoying low-cost and even no-cost power year-round. Additionally, many property owners donate those older panels to schools or other facilities, so they still get some use!

Are Solar Panels Worth It?

Homeowners often wonder if solar panels are worth the cost, as a typical installation might cost a few thousand dollars. To help you decide on a solar installation, note some advantages of a solar array for your property:

  • Solar power means less pollution produced by local power plants. In turn, you can leave a greener planet to the next generation by choosing solar.
  • A solar power installation lowers and even eliminates your energy bills year-round. You can then pocket those savings or upgrade appliances and electronics without worrying about increasing energy costs.
  • A solar panel system often increases property values! In turn, you can build equity faster and sell your property for more money if you ever decide to relocate.
  • Choosing solar for your property often encourages neighbors to do the same. The more properties with solar power panels, the less pollution produced by energy plants overall.
  • Solar panel installation is very labor-intensive. Consequently, you support local jobs and the economy overall when you schedule a solar installation.
