What is solar energy? 10 Important things to know photovoltaic (PV) solar panel system
In short, solar energy systems also known as solar panel systems, solar power systems, solar photovoltaic systems or solar PV systems convert sunlight (a form of energy) into electricity. You can use the electricity produced by your solar photovoltaic (PV) system to power your house, or your business.
What is Solar Energy?
Solar energy is the energy emitted from the sun (a natural nuclear reactor). Our planet captures more than billions of photons (tiny packets of energy) from the sun every day. These photons control the climate and support life on earth.
Where can we use solar panel system?
Today, solar panels or solar energy systems are used for several purposes, which fall into these three main categories:
Residential solar energy systems: Residential scale solar panel system typically ranges between 1 and 20 kilowatts (kW) where you can mount solar panels on your roof or in open ground.
Commercial solar energy systems: Commercial scale solar PV systems are larger than residential solar energy system and are installed on commercial properties for electricity purposes.
Utility solar energy systems: Utility scale solar power systems are typically larger than the rest. Their installations can produce electricity starting from a few megawatts (MW) up to gigawatts (GW) range. They are used to provide solar energy to a large number of utility customers.
How Solar Energy Works
1. Solar panel systems help you reduce or eliminate your bills.
If you are a homeowner or a business owner, utility (electricity and gas) bills take up a huge chunk out of your monthly income/ savings. Through solar financing, adding a customized solar energy system to your property can drastically reduce or even eliminate your utility bills and you can start seeing immediate savings.
2. Solar power system saves you from load shedding.
If you have a solar energy system installed, you do not need to worry if your utility has a blackout. Load shedding does not affect you and your family in any way when you are on solar.
3. Solar panel system gives a great return on investment.
Installing a solar panel system provides an even better return than stocks and prize bonds. Moreover, it is hassle free, compared to all the running around you will be doing when you are playing in the stock market. It is the right time to make that investment, as solar photovoltaic technology is improving day by day, solar energy systems are becoming cheaper and more durable.
4. Solar photovoltaic systems have become more and more robust.
Solar PV panels are made of hardened glass and can withstand all weather conditions (snow, rain, and high winds). They can even extend the life of your roof by protecting it from daily wear and tear. They are becoming more and more durable due to technological advancements in the solar industry.
5. Solar energy systems can produce electricity for more than 20 years.
Most solar panel manufacturers offer 25 years product and performance warranties, which guarantee that their panels will continue to generate electricity for 25 years.
6. Solar photovoltaic panel systems require little or no maintenance.
Except for unforeseen circumstances, solar PV panels are almost maintenance free. All they require is periodic cleaning, usually two times a year.
7. Solar PV panels can be installed almost anywhere in Pakistan.
Being a solar-rich country, most locations in Pakistan get enough sunlight to produce sufficient electricity from solar panels. The most important factors to consider when you evaluate your solar panel options are the rate at which you pay your electricity bills, your site-specifications, and the incentives available to you.
8. Solar energy systems can be grid-tied or off-grid.
Depending on your selection, you can choose to remain connected to your utility’s grid in case you want to sell your excess electricity. Alternatively, you can choose to completely go off-grid and be independent from any grid outages and blackouts.
9. Solar power systems helps you save money
There are plenty ways in which you can save money by installing solar energy systems. One way is by selling by excess and unused electricity back to the grid. You can gain credits from your utility company, which can help you in times of need. Another is in terms of your property value, if your house has a solar power system installed, it will fetch a better price in the real estate market.
10. You can install solar panels anywhere on your property.
Solar panels can be installed practically anywhere on your property, provided that area receives direct sunlight for most of the day and is not shaded by trees or buildings. Most panels that face south will produce the most electricity, but your panels can also face other directions depending on your location.
