Solar power is the ability to convert energy from the sun into usable electricity. Sunlight is either directly harnessed as thermal energy (heat) or through the use of photovoltaic cells in solar panels and transparent photovoltaic glass.
Solar-electric or photovoltaics (PV) technology converts sunlight directly into electricity. PV can provide electricity for residential and commercial buildings, including power for security lights and air conditioning. It can also produce power for pumping water, electrifying fences, or aerating ponds.
Solar Panel Components
What role do these components play?
– The Encapsulation / Back Sheet provides a layer of protection for the solar cells from the environment and provides electrical insulation.
– The Frame is typically made up of aluminum and is necessary to provide structural stability and for mounting the panels.
– The Solar Cells are connected in series via Busbars and Cross-Connectors.
The primary difference across solar panels is the types of solar cells they utilize. A solar panel is broken into two cell types: monocrystalline and polycrystalline.
Monocrystalline solar panels – Are made with silicon wafers cut from a single crystal. Hence the name “monocrystalline.” For the most part, monocrystalline panels are capable of a higher efficiency compared to polycrystalline panels because they typically use a higher grade of silicon.
Polycrystalline solar panels – Like Monocrystalline Solar Panels, Polycrystalline solar panel are also made from silicon. The primary difference is that Polycrystalline solar cells are made by melting together many fragments of silicon rather than from a single silicon crystal. While polycrystalline solar panels are typically less efficient than their monocrystalline counterparts, they often have a lower price point.
It doesn’t matter if you get a monocrystalline or a polycrystalline solar panel. The most important element is to ensure that you will maximize your savings and have a low cost of maintenance. That is why it is important to buy a brand that stands by a performance guarantee that lasts at least 25 years.
How Long do Solar Panels Last?
Solar panels can last anywhere between 25 up to 30 years or even more. Though, this doesn’t imply that the solar panels on your rooftop will stop generating electricity after a couple of decades. It just indicates that the energy production of the panels will decrease by what their manufacturers consider optimal
Do Solar Panels works on Cloudy and Rainy days?
Solar panels work perfectly fine during cloudy or rainy days. Though they are most efficient during sunny days because of the direct sunlight that comes from the sun, solar panels can still generate power during rainy or cloudy days since the solar cells on the solar panels are powered by light and not by heat. High heat can even cause your solar energy system to work less efficiently. Thanks to today’s technology, they undergo rigorous testing to ensure that they run efficiently and effectively.
What are the advantages of using solar power?
There is a reason why solar energy has become a trending topic when talking about renewable energy. Solar energy is a renewable form of energy and thus is sustainable energy, and it has now proved to be extremely beneficial – not only for the environment but also financially.
Here are just a few reasons why you might choose solar over another source of power:
Renewable Energy: Sunlight is an endless source of energy. The sun’s rays can be stored for energy over and over again without depleting the source.
Lower Electric Bills: Solar power costs just a portion of what you pay the utility company each month. An accurately sized system can cut your electric bill up to R0.
Remote Power: Living in a remote location may be too expensive or impossible to run power lines into your home. Solar power systems generate energy when you can’t take into the power line.
Improve Property Value: Homes equipped with solar systems sell for 3.74% more than homes without solar.
