considered, making it an option where never before possible. SPG Solar Floatovoltaics ® makes it possible for commercial and government users with little available rooftop or land space to float solar on water instead, and at the same time gain triple benefits: conserving land and water, while generating clean, renewable energy. Using proven and cost effective floating technology; fresh water irrigation ponds, lakes, or reservoirs become revenue-generating, power producing platforms.
Challenge
The challenges of developing large-scale renewable energy solutions where land and rooftop space are at a premium and for conserving increasingly scarce water resources around the world.
Problem Solved
The solutions provided SPG Solars Floatovoltaics include: 1. Eliminates the need for land or rooftops. 2. Reduces water evaporation under the floating arrays by up to 70 percent. 3. Improves water quality by providing coverage from the sun that minimizes algae growth and reduces the need for water treatment chemicals and associated labor costs. 4. Provides shade below the panels, lowering the water temperature and 5. Improves power output from the solar panels up to 1% more power generated using Floatovoltaics. SPG Solar Floatovoltaics provides these solar generated power solutions agribusinesses, water agencies, wastewater treatment facilities, mining ponds, and hydroelectric reservoirs and utilities; among others.
Noteworthy SPG Solars Floatovoltaics®, has changed
the way solar power is now considered, making it an option where never before possible. Solar customers around the world can now install a floating system that is priced competitively to ground based, single axis tracking solar systems.
In Detail
1. Structure a). Steel frame with HDPE floatation b). All steel is Galvalume (AZ- 55) or hot dip galvanized c). No structural steel is in contact with water 2. Engineering a). Designed per 2010 IBC, 85mph, Exposure C b). All electrical components are NEMA 4X or IP67/68 c). Reports available: d). ZFA Structural Engineers (stamped) e).

Only other components in contact with the water are polyester mooring line, galvanized steel cables and shackles, and aluminum grounding plates 4. Array Layout and Site Parameters a). 3 acres per MW b). pH between 6.0-10 c). No walkway to the array for security, safety and cost d). Accommodate a wide water level variation e). Mooring can be installed on land or submerged 5. Maintenance a). Standard 10 year comprehensive O&M contract with annual inspection included in system cost. Extended O&M is available. b). Wires protected from abrasion c). Wireway protected by steel shed d). Stainless, brass and galvanized mooring hardware
e). Upsized polyester mooring line with UV protection f). No extra maintenance is expected with Floatovoltaics vs. other PV deployment systems
Innovation
Redesigned and engineered to be cost competitive, SPG Solar Floatovoltaics? makes it possible for commercial, industrial and government users with little available rooftop or land space to float solar on water.
All Eco Energy
All Eco Energy is a company which supplies quality products to the industry on a wholesale basis as well as completing residential and commercial installations. From a standing start the company has installed over 500 installations in 6 months and is now offering the Free carbon Solar programme removing the final barrier for commercial organisations to join in with the solar revolution, the upfront cost. All this has been done without any outside help and in the most positive and gentle manner.
Challenge
Removing the barrier of cost to commercial organisations.
Problem Solved Funding is used to provide the equipment, the FIT is used to pay the funding and so the circle continues.
Noteworthy
It allows commercial organisations to reduce their carbon footprint without any investment.
In Detail
All Eco Energy checks the suitability of the roof then take out a lease on the roof (paying the legal costs of the client). This helps the UK hit its targets re the reduction of CO2, it helps educate the persons within the organisations who take it up and promotes the whole programme of the local production of electricity in a carbon Free manner.
Innovation
This whole programme is not dependant on any grants other than the FiT and there are few barriers to the scheme.
Customer Benefits Customer benefit with carbon free electricity at no cost to themselves and the scheme is self financing.
