A photovoltaic system is a power generation system that uses solar cells to convert solar energy into electrical energy. Domestic photovoltaic systems consist of photovoltaic panels, brackets, batteries (banks) and inverters.
Domestic photovoltaic systems are mainly installed and used by using these unused resources of existing buildings in the home, such as roofs, wall facades, balconies, courtyards, etc.
The use of solar power does not only contribute to the global environmental cause, it also brings many benefits to the homeowner.
Save on your electricity bill
The main reason for choosing to install a photovoltaic system is that it will reduce your household expenses.
I know you dread seeing the electricity bill because of the high cost. With the installation of a system you will pay more than 80% less.
You can use electricity from the PV system during the day instead of from the grid. If you also install a battery, you can store the solar energy that is not used during the day for later use. This can further reduce your electricity bill.
High return on investment
I want to install a photovoltaic system, how much will it cost? How long does it usually take to pay back the money? This is a concern for all homeowners.
The return on investment for installing a PV system depends on two main conditions: the installed PV capacity and the investment in the system.
The cost of the equipment purchased for a PV system, including PV modules, inverters, batteries, cables, mounting brackets, meters, monitoring equipment, etc., will vary with fluctuations in market supply and demand, and is related to the size of the installed PV capacity.
In addition to the purchase of equipment, there are also a small number of costs incurred in the construction, installation, commissioning and grid connection of the system. The larger the installed capacity of the system, some of the basic costs will be diluted, making the unit investment cost lower.
For example, a typical home PV system has an installed capacity of around 5KW and a system investment of around $2,000 - $2,600. Depending on lighting conditions, customer-side tariffs, subsidies and system costs, the system will generally pay for itself in 7-10 years, with the remaining 15 years of electricity generated becoming pure profit.
Installing a home photovoltaic system also makes effective use of idle rooftop resources, creates additional income and is a one-time investment with long-term benefits!
Low maintenance costs
After a long period of use, dirt can remain on the surface of PV modules, causing shading and thus reducing the efficiency of electricity generation. However, as most PV modules have a certain tilt angle, the dirt is washed away with the precipitation. So PV modules are less costly to clean. In addition to this, today's professional installers offer services that include installation, commissioning, maintenance and troubleshooting. You can contract an installer to carry out regular maintenance on your PV plant.
Environmental Protection
Solar energy is a new renewable energy source that is truly green and environmentally friendly. Solar power itself does not use any fuel, does not emit anything including greenhouse gases and other emissions, does not pollute the air and does not produce radiation that is harmful to human health. You can contribute to the fight against pollution caused by conventional power generation (e.g. coal power stations, oil and gas extraction). Carbon dioxide and other harmful greenhouse gases emitted by fossil fuels cause climate change and extreme weather changes on the planet, such as droughts, floods and rising global temperatures. The survival of important animal species is even more precarious under this unprecedented climate change, and some species are even on the verge of extinction. Therefore, the installation of photovoltaic systems to power your home is of great importance for yourself, future generations and nature.
Shade in summer and reduced heat loss in winter
When a large area of the roof is covered with photovoltaic modules, the indoor temperature of the building can be effectively reduced in summer, saving electricity for air conditioning. In winter, the heat loss inside the house can be reduced, reducing heating costs.
No noise
Unlike conventional power generation, photovoltaic power generation does not produce any noise.
Increase the value of your home
A home photovoltaic system is a modern, forward-thinking accompaniment to a house. While many homeowners are interested in powering their homes with solar energy, not all of them will take the plunge. Homes with PV systems tend to be valued higher and sell faster than homes without them. And it can make buyers feel that their new home is future-proof.
A solar photovoltaic system is both a beneficial investment and a sign of responsibility for the environment and people. Installing a photovoltaic system is the smart choice!
