When you think of solar energy, you tend to think of decades-old, inefficient photovoltaic panels delivering electricity. You think of them in fixed positions on the ground in massive utility-scale arrays and on rooftops of businesses, government buildings and homes. Think again, because SunScience has developed as the flagship of their product line a “hybrid” solar system called DG1 that integrates both concentrated and thermal solar power for a highly efficient energy footprint. Future product plans include placing this system on wheels with other essential services such as storage and communications, to deliver solar energy benefits in places not previously possible.
Imagine solar energy benefits to these huge, underserved markets.
- Greenhouse farming. Traditional farming is at the mercy of the seasons, weather, availability of water,and persistence of pests. Greenhouse farming has evolved to control some of these variables, but has remained a niche market, largely due to older technology and high energy costs. The SunScience hybrid solar system will change that.
- Primitive and off-grid communities. One day, off-grid business parks, traditional farms and even military bases will be the beneficiaries of a mobile SunScience energy system. Add to these the thousands of villages with over a billion people across South America, India, China, and Africa that are without electricity, clean water, and Internet connections.
- Disaster areas. Katrina, Haiti and Japan once had municipal services, but in an instant had none. The immediacy and portability of the (future) SunScience mobile solar system can be both life saving and an essential element in population management during chaos.
Greenhouse farming has been practiced for many years, largely for specialty produce. However, changing economics and distribution patterns in the worldwide agriculture industry are causing traditional farmers to seriously consider the merits of greenhouse farming. Food prices are rising rapidly, driven by transport costs as well as competition in the commodity markets from biofuel producers. Not to mention produce from South America and Asia is increasingly being sold in U.S. supermarkets. The emergence of the SunScience DG1 hybrid solar system and discoveries in soil science can now deliver these previously unavailable benefits of solar energy to greenhouse farming:
- A typical pattern of spring planting and fall harvesting, say 6 months, can be extended to 12 months, with the possibility of 2 or 3 plantings per year. And killing frost is never an issue in a greenhouse powered by SunScience.
- Farming will become possible in areas where soil quality or weather are normally prohibitive.
- With control of humidity within the greenhouse, less evaporation occurs, therefore less water usage.
- In a controlled greenhouse environment, pest and disease management is improved.
- According to research in the Netherlands, control of the greenhouse environment can dramatically reduce the growing time by half in some cases, further increasing the number of plantings per year.
- With SunScience’s efficient power system, a farmer does not even need to be on farm land. And plant photosynthesis does not even require direct sunlight. Light rays from energy efficient LED lighting in, say a city warehouse, are sufficient for agriculture.
SunScience is a game changer because of their unique proprietary “hybrid” (solar) power generation system, called DG1, that combines both concentrated and thermal solar electricity generation. SunScience’s “concentrated” solar photovoltaic (CPV) units are smaller and far more efficient than traditional PV panels, extremely light weight and modular. A fixed fresnel lens system eliminates the cost of a dual axis solar tracking system that traditional PV panels require. SunScience’s system produces solar thermal energy with options, one of which is heating water to drive a turbine engine for generating electricity. It can also just heat water, bypassing the creation of electricity, for direct soil heating in the greenhouse. As a result, inventor James Parker, PhD, says “flat glass PV panels do almost nothing for the greenhouse farmer.”
These “hybrid” benefits result in competitive advantages nobody today can match:
- Density — delivers up to six times the solar energy per square foot versus PV panels.
- Cost — energy produced is dramatically cheaper per watt than PV panels.
- Results in a very efficient — cost, space and weight — energy footprint.
- The SunScience hybrid system delivers stored energy in the form it’s needed at the time it’s wanted,
SunScience’s future product plans include their Municipal Mobile Service (MMS), which mounts their DG1 hybrid power generation system on wheels with energy storage capability (batteries) and remotely managed communications. It will be invaluable in serving off-grid villages, communities and disaster areas. These off-grid markets are inadequately served by traditional PV, concentrated PV or thermal solar technologies. What these communities have in common is a need for some combination of basic municipal services such as electricity, power storage, clean and hot water and communications, all available with the MMS platform in 2012. President Dick Kelsey believes “Our MMS unit will be designed to meet the global need for a portable infrastructure that can deliver key services for agricultural, disaster recovery, remote community infrastructure and military applications.”
SunScience Corporation, a Reno-based clean energy compnay, has built a unique hybrid solar technology platform that is the first of its kind in the industry. SunScience’s DG1 platform is a true hybrid system that synergistically combines concentrated photovoltaics and solar thermal collectors in one modular unit. The company is focused on developing and bringing their revolutionary solar hybrid technology platform to market in key vertical markets, beginning with greenhouse farming.
