Homeowners, private companies, and even government institutions are turning to solar panel energy supply.  Why?  Because it is a way to reduce utility bills and minimize carbon footprint.  You may be wondering how these solar panels work.

They are devices that convert sunlight into electricity through the photovoltaic (PV) effect.  Solar panels are composed of multiple solar cells and each cell absorbs photons (light particles) from the sun.  From the solar cells, photons knock electrons loose from their atoms, creating a flow of electricity.  The electricity produced is in the form of direct current (DC), and an inverter is used to convert it to alternating current (AC).  This generated AC power can now be used to power appliances and lights, stored in a battery, or even sent back to the grid.  

If you’re new to the world of solar panels, don’t worry.  The solar panels installation in Melbourne is actually quite manageable with the right preparation.  So, here’s a beginner-friendly guide to orient you on what you need to know about solar panel use.

Understand Solar Panel Basics

Solar panels have a great impact on managing your electric bill.  But, first of all, you must be aware of what are these panels for, what materials they are made of, how they work, and what factors should be considered for their installation.  You need to be aware of these key terms:  photovoltaic cells, inverter, and battery storage.

Assessing Your Home for Solar Panel 

Not all homes are compatible with solar panel installation.  You should consider how durable is the roof that will accommodate the panels.  So, it is best to repair or replace it first before installing a solar panel of 25-30 years lifespan.  The more sunlight your place receives and minimal shading, the better.  Roofs that face south, southeast, or southwest in the Northern Hemisphere are the best.

Calculating Your Energy Needs

Check your electrical consumption measured in kilowatt-hours (kWh) found in your utility bill.  From here, your average monthly usage will help you determine the size of your solar equipment.  

Choosing Your Solar Panel Type

Monocrystalline panels are the most efficient and durable but more expensive.  Meanwhile, polycrystalline is less efficient but more affordable.  And the thin-film panels are lightweight but have less effective performance.  However, thin-film is best for unconventional shapes or limited-space roofs.

Picking an Inverter

Connecting all the panels in a series is the feature of string inverters wherein if one panel is shaded, the entire system’s efficiency drops.  So, this is a solution for areas with minimal shading.  However, microinverters installed on each panel allow each panel to work independently making it useful if the roof has shaded parts.

Hiring a Professional Installer

A licensed installer can work on the permits and make sure everything complies with building codes.  They also offer warranties that cover their work and the equipment.  And of course, they are trained to manage whatever risks or problems that may be encountered before, during, and after the installation.

Navigating the Costs and Incentives

Learn about the incentives that can offset the cost like federal tax credits, state and local incentives, and net metering.

Maintenance of the Equipment

Occasional cleaning is needed, but more frequently if you live in snowy or dusty areas.  At the same time, inspection especially by a professional will ensure that it’s working optimally.  You, yourself can actually track its performance with apps or online dashboards.

By being aware of these considerations, you’re on your way to a rewarding investment, not only for your pockets but also for the environment.

One of the subtle architectural elements in the room that adds more depth and dimension to it is the cornices. Various home trends may be introduced each season, but you can expect that cornices are still a staple design element in homes. These decorative moldings go way back and are still being used today as both aesthetics and protection of the top wall from moisture. But who was the first to use this element? In today’s article, let’s explore how different cultures and architectural styles have influenced the design of cornices.

How were cornices used in ancient times?

From being used as decorative elements in temples and places of worship to being used as complementary design elements, cornices have been present in structures and date back to ancient civilizations. Although the Romans and Greeks have popularized it, cornices are also evident in Egyptian architecture. The Egyptians have ornate cornice designs that are carved with hieroglyphics and other motifs. Back then, they only had limited building materials, so the cornices were usually made of stone. Cornices were used as wall protection from the scorching heat of the sun.

In contrast to the Egyptians, the Greeks and Romans explored more uses of cornices. Aside from protection, they relished using it as a decorative element and introduced various designs. The Parthenon, one of the prime examples of Greek architecture, has dentil cornices with bed and reel motifs. Roman architecture drew inspiration and adopted their design, which we can see in iconic structures like the Colosseum.

The evolution of cornice designs from the medieval to the Renaissance era.

Decades later, cornice design improved further, becoming more complex. Gothic architecture stood out with its towering spires and domineering buttresses, so it’s only natural that even the smallest architectural elements also followed suit; its cornices boast of gargoyles and every design motif possible. Apart from keeping water away from the walls, the cornices were also used as channels to direct rainwater away from the structure. 

In contrast to the Gothic period, the Renaissance era saw the return of classical designs. They imitated the structures and added classical motifs like dentils and ogees. By then, the Romans had also introduced new building materials like plaster and concrete, which made them a lot sturdier.

The cornices of today: embracing modern and minimalist designs.

The cornice designs of today are much simpler and derived more from the Greeks and Romans. Some of the more prominent designs we see these days are a mix of dentils, ogees, geometric, and minimalist cornices. Some opt to paint their cornices the same color as their walls, while others prefer to choose bold hues to make a bold statement and highlight the ceiling.

In terms of building materials, there are a variety of options, like plaster, wood, and even metals.

To wrap it up, cornices remain one of the enduring elements of a building that serve both as ornaments and protection. By understanding its history, we can become more appreciative of how it’s incorporated into building designs.
