Solar PV Systems
At TopSolar, our expertise has no limits. Whether it’s upgrading your home’s energy efficiency or building a MW power plant, we approach every project with the same mechanical excellence and commitment to quality. We offer turnkey solutions tailored to the needs of each space and the ambitions of each investor.
Rooftop Solar
For Residential & Commercial Buildings
The unused surface of your roof or flat roof is an untapped energy resource. We transform your building into a clean energy production unit, offering immediate reductions in electricity bills and energy independence.
• Ideal for Net Billing: Maximize simultaneous self-consumption.
• Aesthetic Integration: Use of highly aesthetic frames (e.g., Full Black) that respect the architecture of the building.
• Increased Value: Upgrade the energy class and commercial value of the property.
Ground-Mounted Solutions
For Businesses, Industries & Farmers
For professionals who have unused land (plots, agricultural land near facilities), ground-mounted systems are the most efficient solution. They offer ease of installation, optimal orientation for maximum production, and easy access for maintenance.
• Reduction in Operating Costs: Drastic cost reduction for energy-intensive industries and crafts.
• Agricultural Photovoltaics: Special solutions for farmers (e.g., for irrigation) and the possibility of applying Agrivoltaics (dual land use).
• Design Flexibility: Possibility of using fixed bases or trackers (solar panels) to increase efficiency.
Utility-Scale PV Parks
For Investors & Infrastructure Projects
As an EPC (Engineering, Procurement, Construction) Contractor, we undertake industrial-scale projects ranging from MW to GW. We have the experience to manage complex medium and high voltage interconnection projects, ensuring the fastest and safest electrification of the park.
• Maximum ROI: Design focused on optimizing the LCOE (Levelized Cost of Energy) and the internal rate of return (IRR) of the investment.
• Project Management: Full undertaking of the licensing process, implementation studies, and substation construction.
• Bankability: Use of equipment from Tier-1 manufacturers that ensures the project’s financeability and longevity.
Net Billing
Net Billing (Simultaneous Self-Consumption) is the next step in the energy transition. Unlike traditional Net Metering, where offsetting was done at the energy level (kWh), Net Billing introduces real-time monetary offsetting.
How does it work in practical terms?
The mechanism is based on two simultaneous processes:
• Self-consumption: The energy produced by the photovoltaic panels is consumed directly by the company’s electrical appliances or machinery. The consumer pays nothing for this energy (neither energy costs nor regulated charges).
• Surplus Export: Energy that is not consumed at the time of production is fed into the grid (HEDNO). The producer is compensated for this energy based on the Market Clearing Price (MCP) of the Energy Exchange.
The Financial Benefits for Your Business
For those of you looking for the best return on your investment, Net Billing offers:
• Immediate Liquidity: Surplus energy is converted into a credit balance on your electricity bill, drastically reducing the final amount payable.
• Protection from Instability: By reducing dependence on the grid during peak hours (daytime), the business is shielded from energy price fluctuations.
• Multi-year Contract: Compensation for energy fed into the grid is guaranteed through a contract with the Hellenic Electricity Market Operator (HEnEx), offering a stable investment horizon.
Virtual Net Billing: Solution for Remote Units
One of the most powerful applications is Virtual Net Billing. It allows a business or municipality to install a photovoltaic system in one location (e.g., a sunny plot of land) and offset the value of the energy produced against consumption in other locations (e.g., offices in the city center, hotels, or pumping stations).
The Importance of Storage (Batteries)
In Net Billing, adding a battery changes the ROI (Return on Investment) data:
• Increased Synchronization: You store energy at noon and consume it at night, avoiding the purchase of expensive electricity from the grid.
• Maximizing Benefits: Self-consumption is always more profitable than selling energy to the grid. The battery ensures that the largest percentage of your production remains “within the walls.”
Why is TopSolar your partner in Net Billing?
1. Specialized Study Software: We use advanced simulation tools to predict the degree of synchronization of your business, ensuring that the system is neither “too small” nor “too large.”
2. Subsidy Management: As consultants with experience in ESPA and the Development Law, we integrate the technical project into the appropriate financial framework for maximum subsidy.
3. High-End Equipment: We select inverters and panels that support smart energy management for automatic optimization of net billing.
