We are looking to buy complete solar systems for brokering to commercial premises within the Asia Pacific region, and would like info for the purchase of such systems to generate roughly 5,300 Watts of electricity power at any point of time. Please also advise how many solar panels we would need to generate that much electricity based on the maximum wattage of your solar panels (i.e. 300-400 Watts). The technology should allow backup storage/ battery in the event of the main system failure. I would like to know how your system would take care of this. Please provide cost estimates/ data facts/ guarantees and quality assurances (CE/ ISO compliance). This is not a one-off purchase as we will buy volume based on client demand, which we expect to be high. We already have 1 firm order. Show More
