The system includes 10 kW of solar panels, typically comprising 22 panels of 475W each, or a similar size. We offer any brand of solar panels available. Our preferred inverter-battery system is Sigenergy, which is IP65 rated and compact, allowing for installation directly behind the solar panel array. We use certified aluminium mounting frames for the solar panels, which are usually installed on ground screws or concrete blocks if the ground conditions do not permit driving in 1.5m long screws. The ground-mounted system typically adds an extra cost of around $3,000 to $4,000 compared to roof installations.
