What is Photovoltaic?
Photovoltaic is a technology that allows the conversion of solar energy into electrical energy, exploiting the photovoltaic effect. Photovoltaic panels, made up of photovoltaic cells, capture sunlight and transform it into direct current electricity.
When photons in sunlight hit the material, they transfer their energy to electrons, allowing them to flow as electric current. Each cell produces about 0.5 volts, so the cells are connected in series within the solar panels to obtain useful voltages.
Photovoltaic panels can be installed on rooftops, canopies, pergolas or on the ground, and are able to capture both direct and diffuse sunlight. The electricity produced can be used to power electrical appliances or fed into the electricity grid.
Photovoltaic energy has great advantages for the environment. Here are some reasons why it is considered a renewable and sustainable source:
- It is a clean energy source that does not produce harmful emissions or radioactive waste
- It exploits an inexhaustible and free energy source like the sun
- It significantly reduces dependence on highly polluting fossil fuels such as oil, coal and natural gas
- It helps fight climate change and the greenhouse effect, thanks to the lack of CO2 emissions
- It does not produce noise or acoustic pollution, unlike traditional power plants
- It has a low environmental impact even in its use and disposal, as photovoltaic cells are easily recyclable
- It does not involve the use of water, unlike other renewable sources such as hydropower
- It can be integrated on a large scale even in remote areas not reached by the electricity grid
According to a study published in Renewable and Sustainable Energy Reviews, photovoltaic energy could meet up to 69% of global energy demand by 2050, with enormous benefits for reducing greenhouse gas emissions.
Benefits for Companies
The adoption of a company photovoltaic system involves various economic and strategic advantages for a business. Let’s analyze them in detail:
Savings on Electricity Bills
Self-consumption of solar energy produced by the system reduces electricity purchases from the national grid, lowering spending on electric bills. Savings can reach up to 70-80% of the cost of the bill for companies with high daytime consumption.
Sale of Surplus Energy
The energy produced and not immediately self-consumed can be fed into the national grid, receiving an incentive on production thanks to the Net Metering mechanism. This results in additional earnings on the investment in photovoltaics.
For the installation of photovoltaic systems, personal (Irpef) or corporate (Ires) income tax deductions are available up to 50% of the expenditure incurred, to be divided into 10 equal annual installments. This greatly reduces the costs of the initial investment.
Photovoltaics convey a green and sustainable image of the company, which is increasingly appreciated by customers and investors. This can translate into a competitive advantage in the market.
The company becomes more resilient to possible energy crises or power outages in the national grid, protecting the continuity of production processes that can rely on solar energy.
Added Value for the Property
A photovoltaic system increases the value of the company’s property and improves its energy class. This can result in greater marketability in the future in the event of a sale.
The use of solar energy to power production processes or business activities makes them more sustainable and less dependent on fossil sources.
How to Maximize the Benefits
Before installation, it is important to make some assessments to maximize the benefits of a photovoltaic system for your company:
- Optimal sizing based on electricity consumption and available space, to maximize self-consumption and production
- Cost-benefit analysis over the long term considering savings, incentives, deductions
- Choice of optimal exposure and tilt of the panels
- Use of high quality and durable components to ensure performance over time
- Possible combination with storage systems (batteries) to store production surplus
- Integration with other company energy systems
- Monitoring of production and energy consumption data for optimal management
- Scheduled maintenance to preserve the system’s performance over time
