Swiss start-up Freesuns has developed solar tiles for building-integrated PV it claims can be used on historic as well as new buildings. Freesuns chief executive John Morello said the tiles can be sized to completely replace conventional roof tiles in fiber-reinforced concrete, with all three models able to potentially cover 100% of a roof surface, including on complex roof layouts. Every tile hosts an electrical safety circuit to help prevent fire-risk, the company said, adding the product is ultra-resistant as it is manufactured with double tempered glass. Standard Standard solution the Solaris Classic is a 525mm by 460mm tile which reportedly delivers 154 W per square meter. It costs CHF292 (€276), excluding VAT and Morello told pv magazine, “This value is just an indicative value as the price can change depending on the complexity of the project.” The tile – glossy black with silver lines – is said to be ideal for new-build or renovated structures as it offers a modern architecture style.

Freesuns said another, 160m2 residential roof in Genolier boasted capacity of 24 kW. Black The Premium Black model is a 420mm by 400mm product with a slightly lower output of 136 W per square meter at a price of around CHF304/m2. The model is recommended for modern architecture and for the replacement of cement tile roofs. Heritage The Heritage product is the most expensive, at around CHF308/m2 and reportedly offers power output of 128 W/m2 from the same dimensions as the Premium Black product, although Morello said all three versions are available in smaller formats to ensure complete roof coverage as an option.

The tiles were installed on a small house located in the 18th century Grand Chalet of Rossinière, one of the oldest chalets in Switzerland. “For such an important heritage property it was critical to preserve the historical context in the appearance of the roof so it remained sympathetic to the site,” Freesuns said. “It was also a challenge to convince the local authorities charged with protecting the heritage of the Grand Chalet to allow solar on the roof of this building.” The roof of the small house of the historical building now hosts 8 kW of PV capacity across 54/m2. The Heritage tile is also being used on a 168 kW project under development on a 1,200m2 roofspace at another historic building in Switzerland. Freesuns said the tiles come with a warranty which guarantees they will maintain 90% of power output after 10 years and more than 80% after ...

From pv magazine Latam. Colombian state-owned oil company Ecopetrol has announced plans for a 50 MW solar park which will be owned by its Cenit hydrocarbon transportation and logistics subsidiary. The fossil fuel company said the facility will be in the Colombian municipality of Castilla La Nueva, in the department of Meta, and will generate clean electricity for the San Fernando and Apiay pumping stations as well as oil fields in Castilla, Chichimene and Apiay, in the Eastern Plains. Construction of the 46ha solar plant, which will feature more than 100,000 panels, will begin in the middle of the year with commercial operation slated for December. At that point, the facility will be the largest self-consumption power plant developed in the country, more than twice the size of the 20.4 MW Solar Castilla Park finalized by Ecopetrol in October. The oil business, formerly known as Empresa Colombiana de Petróleos, announced plans to invest in solar energy in August 2018. pv magazine in May reported on the 700 MW Sebastopol PV project approved by the Colombian authorities. That facility, in the town of Cimitarra in the Santander department, is being developed by Sebastosol SAS ESP and is likely to supply power to the Sebastopol refinery in Cimitarra belonging to Ecopetrol.

The Turkish government has decided to cut the one-off administrative fee applied to rooftop PV systems, the country’s official journal has stated. The tariff, which includes an additional 18% VAT payment and is paid for securing approval from the authorities, will be almost halved from TRY529 ($87.37) to TRY278 for owners of such ‘unlicensed’ PV systems with generation capacities of 10-100 kW. For 100-300 kW systems the fee will fall 30.7%, from TRY1,528.50 to TRY1,058; 300-500 kW arrays will see the fee fall 3.1%, from TRY2,309.50 to TRY2,236.50; for 500-700 kW installations it will reduce 7.7%, from TRY4,089.5 to TRY3,773; and for 700 kW-1 MW facilities there will be a 1.1% saving, with the charge reducing from TRY5,202.50 to TRY5,147.50. Rooftop rules The changes to the admin fee come ahead of expected improvements in the country’s rooftop PV provisions, with an announcement expected in May. The Turkish solar market is expected to grow by at least 1 GW of generation capacity annually over the next decade. The nation hit 5,995 MW of installed capacity at the end of last year, most of it in the form of smaller, unlicensed installations. A Solar Energy Roadmap published by the Turkish PV association in October said the country could install 38 GW of solar by 2030. That conclusion came after a report published by Turkish renewables analysis company the Shura Energy Transition Center in May 2018, which predicted solar could pass 20 GW by 2026.

PowerGen has installed a new mini-grid in Nigeria and has signed a contract to develop nine more similar installations. Its investments in the country’s booming off-grid market are backed by the World Bank. On Dec. 7, the Kenya-headquartered off-grid systems developer connected a mini-grid system in the community of Rokota, Niger State. The project serves about 3,000 people with reliable clean energy, it said. PowerGen also recently signed an agreement to develop nine more mini-grids throughout the state, which is Nigeria’s largest. REA Nigeria said the projects are all supported by the World Bank’s $550 million program for off-grid energy development in Nigeria, which they jointly operate. pv magazine first reported about the program in October. Mini-Grid Acceleration Scheme The World Bank’s Performance-based Grant Scheme is not the only initiative aimed at ramping up Nigeria’s mini-grid sector, as REA Nigeria recently ran a tender based on its so-called Mini-Grid Acceleration Scheme (MAS). The four developers that won the MAS tender will deploy their mini-grid projects with an “in-kind partial capital grant” in the form of procured distribution and metering equipment, as well as technical assistance.” A spokesperson for REA Nigeria said that the four winners will “build a total of 24 mini-grids to meet up with the required minimum connections of 3,500 [per lot] with each mini-grid not exceeding 1 MW.” They will build the PV-powered mini-grids in the states of Niger, Oyo, Anambra, Delta and Edo. The installations are expected to be operational by the end of July 2020. The association emphasized the importance of the public-private partnership approach used in the MAS tender. However, private developers will own all of the projects, similar to the World Bank’s scheme. The developers and the communities will negotiate the tariffs at which the electricity will be sold, in line with Nigeria’s Multi-Year Tariff Order (MYTO). The MYTO is a tariff model established by the Nigerian Electricity Regulatory Commission (NERC) “that seeks to reward performance above certain benchmarks, reduce technical and non-technical commercial losses, and lead to cost recovery and improved performance standards from all industry operators in the Nigerian electricity supply industry,” said REA Nigeria. Specifically, MYTO “is used to set wholesale and retail prices for electricity in the industry by employing a unified way to determine total industry revenue requirement that is tied to measurable performance improvements and standards,” the REA Nigeria spokesperson added. The MAS is supported by the European Union and the German government in cooperation with the Nigerian Energy Support Program (NESP) and Germany’ GIZ development agency. The Interconnected Mini-Grid Acceleration Scheme REA Nigeria said that the MAS should not be confused with the Interconnected Mini-Grid Acceleration Scheme (IMAS). Both programs are funded by the same stakeholders via the Nigerian Ene...

From pv magazine USA. The U.S. residential solar market hit record highs in the third quarter with 712 MW of PV rooftop capacity installed, according to the U.S. Solar Market Insight report by the Solar Energy Industries Association and U.S.-owned analyst WoodMac Power & Renewables. Key takeaways from the report include: The U.S. installed 2.6 GWdc of solar in the third quarter, a 45% increase year-over-year; The U.S. added a record 712 MW of residential solar capacity in the last quarter; California added almost 300 MW of residential PV; The contracted utility PV pipeline hit a record high of 45.5 GWdc; and Total installed U.S. solar capacity will more than double over the next five years. New growth drivers in California Perennial solar leader California installed a record 300 MW of residential solar in the last quarter, although the “growth drivers have shifted”, according to Austin Perea, senior solar analyst for Wood Mackenzie. Perea suggested it is “new-build solar demand” and “consumer interest in solar-plus-storage solutions, as a result of public safety power shut-offs” which are driving the record growth. According to WoodMac, policy reforms continued to hobble development in the key non-residential markets of California, Massachusetts and Minnesota. Positive policy developments in New York, Maryland, Maine and New Jersey, according to the report, could boost the non-residential space in the next few years. The U.S. solar market added 2.6 GW of solar in the third quarter, raising national solar capacity to 71.3 GW. The increase in residential installations helped the U.S. market expand 45% year-over-year and contributed to 15 states having their best ever residential PV quarter. Wood Mackenzie is sticking with its full-year U.S. solar forecast of 13 GW – for a 23% annual growth rate – even though the company has typically tended towards conservative estimates.

German solar project developer Solar-Konzept is planning several unsubsidized solar parks with a total generation capacity of 800 MW across the southern Italian regions of Apulia and Basilicata. Managing director Nikolaus von Einem told pv magazine land and grid connection approvals were already secured for all the projects. Solar-Konzept Italia was only founded in May and swiftly applied to the municipal authority of Brindisi, in southern Apulia, for six solar projects with capacities of 16-98 MW and a total output of 300 MW. “All of these projects are currently being reviewed for environmental impact assessment and a final decision should be taken in early 2020,” said Von Einem. “We hope to obtain final authorizations by the end of 2020 and build the power plants between 2021 and 2022.” Total investment for the facilities is estimated at around €180 million. Seeking power deals Solar-Konzept has applied for environmental impact assessments related to three 20 MW solar parks near Melfi, in neighboring Basilicata, and a 20 MW facility near Taranto in Apulia plus, by Christmas, “another 140 MW, set to be located between the Apulian provinces of Foggia, Bari and Taranto” added the developer’s MD. On top of that, the company is planning further projects to take its projected pipeline to 800 MW. “All our projects are built without subsidies and we will have to look for a PPA [power purchase agreement],” said Von Einem. “The first indicative talks are under way but the project phase does not allow for more serious talks at the moment.” Divisive The executive admitted there is extensive opposition to new solar capacity in Apulia, and particularly in Brindisi. Von Einem said farmers were dealing with the xylella fastidiosa bacterium which has killed more than a million trees in the region but that the regional government also plans to close Apulia’s only coal plant, the 2,640 MW Federico II facility near Brindisi, by 2025. “Apulia actually needs new power generation units,” said Von Einem, adding all of Solar-Konzept’s planned projects intend to host newly planted Mediterranean forest on around 25% of their footprint, in line with guidelines published by the province of Brindisi in August. Struggle for land The opposition to new solar from local authorities and civil groups is mirrored across Italy. Brindisi was a magnet for PV during the five iterations of the Conto Energia feed-in tariff which expired in 2013 and hosts a significant volume of solar generation capacity as a result. High solar radiation and favorable geography were bolstered by regional legislation which permitted solar facilities up to 1 MW in size without the need for environmental approvals. Predictably, that led to large scale projects being developed in 1 MW blocks. Apulia is the capital of Italian solar with more than 2.65 GW of solar generation capacity, according to Italian energy agency the Gestore dei Servizi Energetici, and also boasts the largest average project size – 54.8 ...
