As solar technology is pushing the 25% efficiency mark and the costs in this sector are set to lower each year, solar energy is solidifying its global position as one of the fastest-growing renewable energy sources. That is why more and more companies chose to become prosumers and harness solar energy to cut their electricity bills.
Solar panels consist of numerous smaller units – photovoltaic cells. When sunlight reaches the cells, electrons in the solar panel begin to move, generating a direct electrical current (DC). Wiring between the cells combines the electrical current into one.
The initially generated direct current (DC) is not suitable to power most electric appliances and needs to be converted into an alternating current (AC). To create usable electricity, the solar power first travels to the inverter, where it is converted from direct current (DC) to alternating current (AC).
When solar electricity is converted to alternating current, it is ready to be used by the solar system owner. If the solar panels create more electricity than is needed, it can be sent back to the grid. Usually, PV owners will receive credit for this extra energy that can be used on a future bill, which ensures all-round reduction in electricity cost.
There are four main types of solar power plants based on their installation properties:
Ground-mounted photovoltaic (PV) systems are solar arrays constructed on open fields on a fixed or tracked structure. Such systems offer a well-defined project development process, easier maintenance due to ease of access, and high-performance ratio values. Learn more.
Remote solar parks serve as a solution for businesses seeking to harness solar energy without having to install a PV system of their own. Solar parks enable direct investment in solar projects and make solar energy consumption an effortless endeavor. Learn more.
Rooftop solar power plants are mounted on top of various flat-surfaced or sloped rooftops, converting these unutilized spaces into valuable assets generating green electricity. Learn more.
Floating solar parks utilize previously mostly unused domain – water surface. Solar panels mounted on secure floats are element-resistant and have several unique advantages. Learn more.
As solar cells have no moving parts, they are extremely durable and require little maintenance compared to other energy generators.
If solar cells are not covered with snow, they may function even better in winter as their efficiency increases in lower temperatures.
Solar panels can withstand heavy rains, winds, hailstorms, and other kinds of strong physical impact while remaining completely intact.
The usual ROI on solar projects is 10% – 15% which rivals most of the other types of investments in the market.
Current solar cells have an efficiency rate of 20 – 25% which is more than enough to generate profits. To put it into perspective, regular internal combustion engine cars have fuel efficiency that varies from 15 to 25%.
Within 4 to 7 years, solar panels offset their carbon and energy footprint leaving them with at least 18 years of environmentally neutral operation.
