# Renewable Energy with PPA Contracts | Green Solar PPA

> Green Solar PPA is Whitenergy's service for companies seeking dedicated solar energy through long-term Power Purchase Agreements, with no initial investment and an agreed energy price. The service is available in On Site, Virtual (VPPA), and Full (FPPA) configurations to address different operational needs.

## Page details

- **Source language:** Italian
- **Content type:** Service page
- **Original title:** Energia rinnovabile con Contratti PPA | Green Solar PPA
- **English title:** Renewable Energy with PPA Contracts | Green Solar PPA
- **Source URL:** https://weeg.it/soluzioni-energetiche-per-aziende/esco-energy-performance-solutions/contratti-ppa/
- **Summary:** A solar-energy service based on multi-year PPA contracts, with photovoltaic systems financed and managed by Whitenergy and three configurations for companies with different site and consumption profiles.

## Overview

Green Solar PPA is designed for companies that want access to solar energy in a simple, stable, and sustainable way. Whitenergy builds and finances dedicated photovoltaic systems, while the customer receives green energy without initial costs and at an agreed price.

The PPA (Power Purchase Agreement) supports long-term cost planning, ESG objectives, and emissions reduction. The page presents the service as a measurable energy strategy with economic and environmental benefits over time.

A PPA is described as a multi-year bilateral agreement governing the sale of energy between a renewable-energy producer and a buyer at a defined price that remains stable over time.

## Green Solar PPA configurations

Whitenergy offers three formulas.

### On Site

For companies with suitable space, such as roofs or land, where a photovoltaic system can be installed.

- The photovoltaic system is built directly at the customer's site.
- The solar energy produced is used for self-consumption, reducing grid costs.
- Energy not used can be stored or fed into the grid.
- No initial investment is required: Whitenergy finances and manages the system.

### Virtual PPA (VPPA)

For companies without available installation space but with sustainability objectives and a need for traceable energy consumption.

- Whitenergy builds a dedicated photovoltaic system at an external site.
- The energy produced is transported through the grid to the customer.
- The customer can include the system in ESG reporting and environmental communication.
- The page states a fixed price and carbon-footprint benefits.

### Full PPA (FPPA)

For multi-site companies or businesses with high energy consumption that want broader coverage.

- Combines On Site PPA and VPPA strategically.
- Provides operational flexibility and broader coverage of required energy across multiple sites.
- Supports optimization of self-consumption and balancing between systems.

## Target sectors

The page identifies several sectors where Green Solar PPA can be applied.

### Industrial materials

Companies working with cement, bricks, glass, or construction materials can use Green Solar PPA to cover daily electricity needs of production lines, stabilize process costs, and improve the environmental sustainability of the supply chain.

### Chemical industry

Continuous processes and electricity-intensive plants are presented as suitable for PPA solutions. Photovoltaic energy can reduce exposure to grid-energy costs, with measurable effects on energy bills and company ESG reports.

### Textile industry

Green Solar PPA can supply solar energy for dyeing, washing, and drying machinery through self-consumption, reducing grid load and optimizing product-transformation costs.

### Manufacturing

For multi-shift or automated production plants, photovoltaic PPA provides a stable share of renewable energy, optimizing the energy mix and improving the environmental performance of production cycles.

### Food industry

Food companies can use solar energy for refrigeration, processing, bottling, and washing systems. The PPA model is presented as a way to optimize fixed costs without placing pressure on company liquidity.

### Agriculture

The page gives the same operational example for agricultural businesses: solar energy can supply refrigeration, processing, bottling, and washing systems, while the PPA model can optimize fixed costs without tying up liquidity.

### Healthcare

Hospitals, clinics, and residential care facilities can use a stable and sustainable energy supply for HVAC, lighting, and backup systems. The solar PPA combines operational security with emissions reduction that can also be reported in social-impact reporting.

### Hospitality

Accommodation facilities can use locally produced solar energy for air conditioning, domestic hot-water heating, catering, and services. The PPA is presented as providing tangible savings that can also support environmental marketing.

## Frequently asked questions

### What are PPA contracts?

PPA contracts are multi-year bilateral agreements governing energy sales between a renewable-energy producer and a buyer at a defined, stable price. Whitenergy's Green Solar PPA lets companies use green energy from dedicated photovoltaic systems without initial investment, supporting energy planning and emissions reduction.

### What advantages does a PPA offer compared with grid energy?

The page states that a PPA provides price stability for the duration of the agreement, unlike grid energy exposed to market fluctuations. It also supports a lower corporate carbon footprint, improved ESG performance, and transparent communication of traceable renewable-energy use.

### Is installation space required?

No. The three formulas address different situations:

- **On Site:** for companies with available roofs or land.
- **VPPA:** for companies without suitable space that still want traceable solar energy.
- **Full PPA:** a combined solution for multi-site companies or high-consumption businesses.

Whitenergy evaluates the configuration according to the company's structure and consumption.

### Are there initial costs?

The page states that there are no initial costs under the Green Solar PPA model. Whitenergy covers the investment for design, installation, management, and maintenance of the system. The customer pays for the energy consumed at an agreed price without tying up capital or bearing unexpected system costs.
