Performance winner:
With a charging current of 6.4 amps within the test setup, the Solara module emerges as the quantitative winner of the test. With a theoretical peak output of 120 watts, this is hardly surprising; here too, together with the Büttner/Dometic module, it is the leading performer. It is quite possible that even more power could be achieved, as the charge controller supplied was only 0.2 amps away from its maximum load and heated up considerably during the test. The low-light behaviour (33% residual power) and the reaction to shadows were also convincing, with a minimum of 22% residual power still measurable. The high price is unfortunate. If this were different – and if there were a more powerful controller – the panel consisting of walk-on laminated modules would be good for a top place in the test.
