Everywhere you look, solar panels are gaining ground. In various regions of the globe thanks to naturally sunny weather, it’s no wonder why more and more people make the investment. In addition to the affordability factor and the big drop in component prices, there is also the matter of saving money energy-wise.
But isn’t the whole installation process a complicated one? And what makes one panel more special than the other?
Apart from providing every customer with the best possible solar panels the market has to offer, we also pride ourselves on keeping people informed. Here are some quick facts, considerations and features about solar, to get you started.
What is a Solar Panel?
Solar panels are made up of silicone cells, which is the magic component for turning sun-rays into energy. Some panels will have a single, solid silicone cell (monocrystalline), while others will have pieces of silicone that have been melted together (polycrystalline). These cells are then fixed inside a frame, and covered with a protective glass.
When the panel is properly angled, it will capture sun-rays and convert it into DC energy. In turn, the DC energy gets converted to AC energy via an inverter, which you can use inside the home for your loads. (tv, fridge, lighting, etc)
Types of Solar Panels
Solar panels are classified into three classes: mono-crystalline (single crystal), poly-crystalline (multiple crystals), or amorphous silicon. Mono-crystalline is indicative of the continuous and unbroken sample of silicon in which the cell is manufactured from. This method uses very pure silicon grown in a complex growth process, and then sliced into wafers that compose the individual cells. This was the first method used to manufacture solar cells, and are still highly regarded for their efficiency ratios.
Poly-crystalline panels are composed of many crystallites of varying size and orientation. These multi-crystalline panels are generally less expensive and slightly less efficient than mono-crystalline modules, yet lately the difference in efficiency is very small. Like their mono-crystalline counterpart, the cells are also cut into wafers that make up the individual cells of a solar panel.
Amorphous solar panels use the non-crystalline, allotropic form of silicon, in which a thin layer of this silicon substrate is applied to the back of a plate of glass. These panels are much cheaper and less energy efficient, yet they are more versatile in how they can be used. For example, amorphous solar panels can be manufactured into long sheets of roofing material. Thin Film solar panels also fall into the amorphous category. This type of cells can be mounted on a flexible backing, making them more suited for mobile applications.
Each of the solar panel types is estimated to last at least twenty-five years. Instead of stopping production completely, electricity production will decline a little, gradually, over decades. The longevity of a solar panel refers to the number of years before the unit starts producing only 80 percent of its original power rating. The industry standard for warranties is 20 to 25 years, although it is not uncommon for panels to produce adequate power for over 30 years.
Off-Grid Solar versus Grid Tied Solar
Solar panels are used extensively in rural areas, where access to the grid is non-existent or inaccessible. These installations are called off grid (or independent, stand-alone, island) solar power systems, and require the use of batteries to store the energy for use at night or on long stretches of overcast weather.
The energy stored in the batteries leaves the batteries as DC electricity which can power DC appliances (as in RV’s) or be converted to alternating current (AC) for use with conventional appliances. Much like running your own mini utility company, this method gives you full independence from the national grid.
- Grid Tied Solar
You can eliminate the cost of batteries by going with a system that connects right into your home’s main junction box and use the grid as your power source at night or on long stretches of inclement weather. These installations are known as grid-tied or grid-interconnected solar systems. This version of solar system enables you to sell any excess power you produce back to the utility companies who have chosen to support “net metering”. Once you are signed up on a net metering program, your utility company will have a smart meter installed known as a Time of Use Meter, which will actually run backwards when you are producing excess power.
It is wise to keep in mind that Grid tied systems without a battery backup, are only functional when the grid is operational. Due to anti-islanding features on grid tied inverters, which protect utility workers from working on a live line, grid-tied systems without a battery back up will not continue to produce power during a power outage regardless of whether you have sunshine or not.
- Grid Tied Solar of course that needs to be connected …
Since solar panels produce DC, or direct current, they must be coupled with a solar inverter to convert the energy from DC to AC, or alternating current. In a grid tied system this can be done by a large central inverter, or each solar panel can be outfitted with its own micro inverter. Once the power is converted to alternating current and its phase is synchronized with that of the grid, it is then tied in to your main junction box, which is ultimately interconnected to the national grid.
What other components and equipment I need for a fully functional solar system?
The inverter has one specific purpose – to safely switch the DC energy from the solar panels to AC energy, which can be used inside the home. Without a solar inverter, you won’t be able to utilize the energy for your appliances or lights. Since the solar inverter is the heart of every solar system it’s logical that you want to invest in a quality inverter; given its critical place in the equation. You can find out more about solar inverters here.
Batteries are an optional components. There are people who use solar power on demand, which means they only use solar energy when the sun is shining. But it also means they don’t have solar power during the night. For the most part, when people install a solar array, they take the battery option as well. Provided that you probably spend most of your day at work and use most energy at night, batteries just makes sense. Naturally, you get different sizes, models, and quality options from world leading manufacturers.
Solar Charge Controller/MPPT
Just like the batteries, a solar charge controller is an optional component. It regulates the current used to charge the battery which comes from the inverter. However, a solar charger does become a necessity if you are using panels with high outputs. If you want to maintain the health of your battery and the overall efficiency of the solar array.
Solar Panel Accessories
Customize your solar panel system and gain a lot more control on your solar system. From monitoring, wiring, strut and other mounting components you can find everything you need to be able to fully commission your system. We have them all.
Converting the Solar Energy
Now, the silicone cell is the magical component that turns the UV rays into DC energy. Once the rays have been harvested and transformed into practical energy, in a manner of speaking, it gets sent to an inverter. The inverter takes the flow of energy through another transformation, switching it from DC energy to AC. The latter is the energy/electricity that gets used inside your home. And just to clarify, the inverter and the solar panel are two separate pieces of solar power equipment.
The Costs of Installation of a Solar System
Even though solar panels were expensive several years ago, in the past years the price drop has been dramatic. Now, it just makes more economical sense to invest in solar panels, because they give you some or full independence from the grid (depending on the size you install), save you money in the long run, and they are environmentally friendly.
In terms of actual pricing, everything depends on your needs and your budget. You can start by adding a solar geyser and test the efficiency for yourself. And from there you can install more.
The good news is that ZEROhomebills.com offers the most affordable panel from the best manufacturers with the highest efficiency levels, right to your doorstep. Only choose between our quality range of panels, which are just as durable as they are impressive.
