Grid Tie Solar System Solution
Posted: Tue Jul 16, 2019 11:15 pm
We've been mulling over power solution for our office for the past long while. Generator vs Solar, and I'm really at the final stages of opting for solar, being in Jo'burg and sun being plenty.
*CONCLUSION:*
Best setup would be solar, no battery bank, Eskom as back-up.
We've been monitoring our office hour consumption, and we peak at 3.2kw once a week (no air-cons or boilers or microwaves in this part of the office/DB.
Ellies (don't crucify me) has quoted around R80k for a 3.6kW setup, using Hoymiles Grid Tie Microinverter. I most likely can "pump back" into the line with the agreement from landlord so I can access any excess for nighttime passive running of office equipments. Our electricity bill is currently around R5k a month (1.5mWh), so will pay system off in 2-3 years which is a good return on investment for an NPO.
Would appreciate the minds of experts and hobbiest alike.
