Conergy Completes 14 Rooftop Solar Power Plants Without Subsidies At Sub-Grid Prices

February 28th, 2013 by  

Conergy, a photovoltaic solar provider, has reportedly installed 14 photovoltaic solar power plants without subsidies or feed-in tariffs (FiTs) in Spain.

Conergy noted that the plants generate electricity at a much lower cost than the average retail price of electricity in Spain, which Conergy said is 15–17 eurocents per kWh.

The solar power plants generate electricity at “just over” 10 eurocents per kWh, which is affordable enough to negate the need for FiTs and any other financial support.

This is a good sign that solar in Spain could reach grid parity nationwide soon. Of course, this is not the first grid party milestone — a First Solar plant in the U.S. has achieved it as well, and some regions (such as the state of Hawaii) are already at solar grid parity — but this is still one of the first reports we’ve seen.

The 14 power plants’ combined electricity generation capacity is 75 kW.

The first of the 14 plants was one on the roof of La Sal Varador, an organic restaurant in Barcelona. The other 13 solar power systems are located on the rooftops of various homes and businesses. The electricity generated from this systems will be used almost 100% on site.

“But,” states Luis Jiménez Gutierrez, managing director of Conergy Spain, “an agricultural business has a different load profile than a restaurant or private household.” As such, Conergy now offers a calculation tool for the design of self-consumption systems without support, which is based on the company’s past experience in this market segment.

“This now allows us to support our partners with the development and realisation of such power plants without any feed-in tariffs and thus advise and support them competently in a changing market.”

  • Grid parity was achieved in Germany few years ago, but this is because retail price of grid electricity is very high for German households. German roof-top solar electricity may cost today as little as 120 euros per MWh and there is a lot more sunshine in Spain.

    First Solar has not yet achieved grid parity. It is right now claiming that it can sell electricity with subsidies at 58 dollar price point, but this is not yet realized and it is not that particularly cheap. Centralized solar plant needs also expensive reserve generation capacity for winter, rainy days and night time production. E.g. in Germany average market price of electricity was €40 / $50 per MWh.

    People often confuse retail prices and generation costs. Because transmission costs are quite high, it is better to go with decentralized roof-top solar production.

      Better to be off the grid with solar power than be charge transmission cost, off grid in the long run will save the planet unlike on grid system.
