Solar for a 3 bedroom with 2 AC units: What should I really expect?
GThe power situation in our area has gone from bad to worse. Last week, we had about four hours of electricity in three days, and I had to keep buying fuel for the generator just to keep the fridge running and make life bearable. At the current fuel price, I spent almost N95K on fuel last month alone, and that is not sustainable. My wife and I have been discussing solar for over a year, but we kept postponing because the initial cost felt too high. Now I am seriously considering it, and we have set aside N3 million for the project. Our home is a 3 bedroom flat with two 1.5HP air conditioners, a refrigerator, and the usual light bulbs. I know the AC units are the big power consumers, and I am not sure if ₦3 million can cover batteries, panels, inverter, and installation for running both ACs for a few hours in the evening. I am also confused about the sizing and the technology choices: should I go for lithium batteries or tubular? How many panels would I need? And what about maintenance and lifespan? Some people say solar is a game changer, others say the batteries will need replacement in a few years and wipe out the savings. I am leaning towards getting a system that can run the fridge and lights throughout the night, and maybe one AC unit for about 5 to 6 hours in the evening, but I am open to suggestions. I would love to hear from anyone who has made this transition, especially for a similar size home. How much did you spend, what system did you settle on, and what would you do differently if you were starting again? Also, what are the practical things you wish you knew before installing? Any guidance would be deeply appreciated.
