Optimizing Floating Solar: Eco-Safe & Efficient Water-Based Energy
Analysis of Emerging Themes & Opportunities: Floating Photovoltaic (FPV) Systems
Based on our discussion, FPV systems are a promising new technology that not only generates renewable energy but also helps conserve water. However, there are some key concerns and areas that need further development, which open up several commercial and marketing opportunities:
-
Eco-Conscious FPV System Design & Materials:
- Need: There are worries about heavy metals from PV cells leaching into the water and the impact of surface coverage on underwater ecosystems, such as light blockage affecting algae and plant growth, and thermal changes.
- Opportunity: Develop and market FPV systems using non-toxic, recyclable, and marine-grade materials. Create designs that optimize light penetration to the water below, like spaced panels or translucent materials where feasible, or manage thermal transfer effectively.
- Marketing Angle: "Sustainable Solar: Powering your needs while protecting aquatic life." "Eco-Safe FPV: Clean energy, clean water."
-
Cost Reduction & Efficiency Enhancement for FPVs:
- Need: FPVs can be up to 20% more expensive to install and may have lower yields if they don't use tracking systems.
- Opportunity: Innovate in mooring systems, flotation devices, and installation processes to reduce upfront costs. Develop robust, cost-effective tracking systems suitable for water environments to maximize energy yield.
- Marketing Angle: "Maximizing ROI on Water: Affordable and Efficient Floating Solar." "Smart FPV: Advanced tracking for superior energy harvest."
-
Integrated Environmental Monitoring & Management Solutions:
- Need: There's uncertainty about the actual evaporation reduction effects, concerns over water quality, and ecosystem impact.
- Opportunity: Bundle FPV installations with integrated sensor networks for real-time monitoring of water evaporation rates, water quality (temperature, dissolved oxygen, pollutants), and aquatic biodiversity. Offer data analytics and reporting services.
- Marketing Angle: "Intelligent FPV: Generating power and providing actionable environmental insights." "Verified Performance: FPV with proven water conservation benefits."
-
Region-Specific & Niche Application FPV Solutions:
- Need: The viability of FPVs depends on the context, such as being more logical in land-scarce, water-abundant regions like the Netherlands compared to land-rich desert areas.
- Opportunity: Develop and market FPV systems tailored for specific applications and environments:
- Reservoirs & Water Treatment Plants: Highlight the dual benefits of energy generation and reduced evaporation/algal bloom.
- Aquaculture: Designs that can be integrated with fish farming, potentially providing shade and power for operations.
- Hydro Dams: Complementing existing hydro infrastructure.
- Industrial Water Bodies (e.g., cooling ponds): Offering on-site power and reducing water loss.
- Marketing Angle: "Tailored FPV: The right solar solution for your unique water body." "Unlocking the Potential of Water Surfaces."
-
Advanced Research & Data-Backed Advocacy:
- Need: There's conflicting information or a lack of definitive data on some benefits, like evaporation reduction efficacy.
- Opportunity: Invest in and publicize comprehensive, peer-reviewed studies demonstrating the full range of FPV benefits and addressing concerns. Partner with academic institutions or research bodies.
- Marketing Angle: "Science-Backed Solar: The proven advantages of Floating PV." "Leading the way in FPV research and development."

Promising research, but we have to be extra careful when introducing solar panels to water. A lot of heavy metals are used in photovoltaic cells and we need to be damn sure the floating panel

Indeed, doesn't make much sense in a country with lots of desert land. It is used in the Netherlands where water is everywhere and land is expensive. They use circular floating platforms that

So it saves 4 feet of water evaporation per year.
That's a fuckton.
And this is ignoring the much larger water savings by avoiding discharges purely to run the hydro when the water is not n

Little (at least per unit area). 100,000 acres is a vast area in solar project terms, enough for 25 GW:

I also want to know this for potential impact on my shingles. If I do spring for solar panels, will it help the roof last a lot longer?
u/NeurogenesisWizard
There needs to be a limit to amount over the surface to prevent dampening underwater plant or algae growth perhaps
u/Hrmbee
Where did you find the comment in the article about having no demonstrated effect on evaporation?
u/20190419
Also, how much heat I's transfered to the water? Is that an issue or do the panels keep it cooler?
u/Arbutustheonlyone
The article itself says that floating panels are 20% more expensive to install; have lower yield because they cannot track the sun and have little to no demonstrated effect on evaporation whi

The water will heat up for sure. In some solar installation they hook up water to improve their efficiency and in return you get warmer water.
Of course generally the days where that works

There are plenty of lead free models available. And the only other heavy metals are copper and bismuth -- both of which are considered safe for water infrastructure.
They also have this safe

They remove 20% of the sun energy that hits them and stop an additional 60% of it entering the water. About half of which is re-radiated.
The entire point is it blocks the energy causing eva
