Hello all, I live in Brasilia, capital of Brazil. I am not exactly new to this forum because have reading it for the last six months.
But the reason I come now is that today my on-grid PV system finally started producing, which makes me proud.
My system consists in 18 x 275W CS6K Canadian modules, divided in 2 strings of 9, totaling 4.95kW DC peak and 1 Fronius PRIMO 5.0-1 inverter.
Modeling this system in SAM resulted in 7,440kWh/y. Brasilia is located at latitude 16 degree south and 3,000ft altitude. The estimated efficiency of the system is 4.12kWh/kW. This production offsets more than 100% of my current consumption, but my consumption is still increasing and I am planning buying a electric car in a few years.
The overall cost, including no only these equipments but wires, mounts, installation and project for POCO, was US$ 1.90/W.
This is the final cost for me since there is no rebates. But there are incentives from the government like exemption for importation and sale taxes on PV generators.
Here POCO uses netmetering model, so all energy injected on grid and not used becomes kWh credits. This credits lasts for 60 months, which after that it expires. The compensation is made on a 1 to 1 basis.
The investment is estimated to be paid in 8 years.
