Solar Trackers or suntrackers are a cheap solution to boosting performance of existing fixed panels. Trackers permanently keep panels in full, direct sunlight, boosting performance upto +50% in summer and +35% in winter.
Trackers can be single or twin axis and either follow the sun via a photo-cell, liquid or by timer.
At Generador-Electrico.com’s premises a Lorentz Etatrack1500 was installed.
With its 15 x 125Wp Kyocera KC series panels (15m2) it has a considerable size, is robust and economic.
We have compared 2 similar installations; only a rough 20 Kms away in a straight line.
Our installation in Ronda (Málaga) with 15 “tracking” panels against 16 “fixed” panels in Yunquera (malaga).
Comparisons were made using the proper Outback MX60′s 64 day history.
Checking one particular day in the month of april that neither of the two systems had been absorbing nor floating (so full power had been fed into the batteries all day long) the following results came up:
Yunquera 16 x 125Wp FIXED panels: Outback MX60 read: 11,8 Kw
Our own installation in Ronda, with 15 TRACKING panels (please note, 1 less): Outback MX60: 17,9Kw.
(Sunny, cloudless day)
You don’t have to be a wizard to see the difference…
Currently our system has new panels, and is currently equipped with 12 x Sanyo HIT 230Wp monocrystalline panels and is currently kicking out around 25 Kw/day For slightly smaller installations the Etatrack 1000 Activ (10m2) and the Feina SF9 biaxial de 9m2 , are available. Also we have the smaller Etatrack 400 Activ (4m2) and Suntracer+ de 2m2.
Recently Etatrack 2000 (20m2) and Feina SF20 have been added.
