Edisun Microgrids, Inc. has launched PV Booster™, the only dual-axis solar tracker strategically designed and built for the commercial and industrial rooftop sector. PV Booster’s transformative technology yields 20 percent better solar rooftop economics than conventional fixed-tilt installations. Profitable rooftop projects can now show an even more significant return. Other projects, once un-bankable, are now economically feasible.
Tracking systems dominate the ground mount market, and almost 90 percent of all systems now include trackers because of the strong economic benefits. In contrast, the rooftop market has not been able to take advantage of trackers previously because of weight, size, mounting, and wind issues. For the first time in the industry, PV Booster solves all four of those issues, allowing the commercial rooftop market to gain all the advantages of tracking energy boost.
By continuously facing solar modules toward the sun, PV Booster increases the energy production by 30 percent versus conventional fixed-tilt installations. This significantly enhanced performance decreases installation payback by as much as two years and increases Internal Rate of Return by two points. Additionally, Levelized Cost of Energy may be lowered by $0.02 per kWh. PV Booster also provides unique value to utility customers that are subject to escalating time-of-day grid pricing. The tracker captures more energy on the shoulders of the day when time-of-use rates are the highest. Those gains reduce time-of-use charges (peak), allowing those customers to achieve even stronger financial returns.
“Although solar costs have dropped dramatically in recent years, rooftop tracking installations have remained both logistically and economically unrealistic for commercial facilities – until now,” said Bill Gross, chief executive officer, Edisun Microgrids, Inc. and founder, Idealab. “PV Booster is the first technology to bring the proven economic benefits of solar trackers from the ground to the rooftop, enhancing returns as well as opening the market to a large and underserved customer base.”
“We have been able to use PV Booster to open up new markets and push marginal projects over the line to make the numbers work,” said Stephen Gates, founder and president, Neighborhood Power Corporation, a global solar developer and financier.
PV Booster is designed for simple, fast installation and features an exceptionally reliable, gearless, lightweight design that keeps operations and maintenance costs low over the lifetime of the system. The technology has a low wind profile and its embedded intelligence automatically retracts modules at night and during periods of high wind. The trackers are powered by a brushless, low-voltage motor that consumes less than 0.01 percent of the total installation energy generated and uses a reliable battery backup unit to maintain operations when grid interruptions occur.
