ESP's Concentrating Solar Power (CSP) system, or EsPOD, is a micro-sized stand-alone parabolic trough-mirror device. ESP has successfully taken proven large scale concentrating solar power technology and adapted it in a proprietary fashion, for micro-generation in the retail consumer market.

Combining a 40% solar efficiency for electricity production, along with a 40% optimization for thermal energy, the EsPOD has an 80% efficiency. The EsPOD produces between 3 kW (3,000 Watts) - 4 kW of electricity per hour in full sunshine. ESP’s EsPODs are completely scalable for larger requirements and can linked together to form a 50 kW system or paired to run larger applications in 50 kW multiples.

The system employs a linear parabolic reflector or trough system that concentrates solar heat to one point only, focusing the solar radiation on thermal oil contained in a vacuum sealed tube. The hot oil moves through a heat exchanger unit within the closed system and heats a reservoir of water, generating a temperature sufficient to bring it to boiling (100°C approx) and generating steam, which in turn powers a turbine, producing energy. After discharging its energy, the steam is carried to a condenser, turned again into water, and re-sent to the cylinder to be then turned again into steam.

The system employs special electronic systems to follow the sun’s trajectory, keeping the trough perpendicular to the rays of sunlight and making the most of solar radiation during the day.

Commercial/Industrial Rooftop Applications

Until recently, CSP was considered to be cost-effective only for utility-scale power generating facilities. Now, however, a new generation of Micro CSP technology has been introduced that can provide thermal energy and/or electricity for a wide variety of small to mid-sized commercial and industrial applications.

• Opportunity to lower electrical costs for commercial applications and fixed costs
• Retrofitted into existing facility
• Scalable in size in 50kW links - (4 systems = 200kW)
• Increase renewable output to fossil fuel ratio
• Tie into existing electrical without interrupting current production
• Reduce emissions and remote power
• Payback estimated within 3 years
