I Priced Out a Solar Setup for My House — Here's What I Found
I’ve been looking into solar for my house. Not because I have strong feelings about the grid, but because my electric bill averages around $150/month and I’d like that number to be lower or gone entirely.
Here’s what I’ve found so far. I haven’t installed anything yet – this is the research phase.
Step 1: Reduce before you produce
Before even looking at panels, it made sense to cut usage. The less power you need, the smaller (and cheaper) the solar system has to be.
The quick wins I found:
- LED bulbs everywhere (this alone cut my lighting usage noticeably)
- Unplugging stuff that draws power while “off” – cable boxes, chargers, old monitors
- Sealing air leaks around windows and doors
Cost was maybe $100-200 total. Not glamorous, but it’s real savings every month.
Step 2: The small starter setup
I looked at what a portable/modular setup would cost to learn the basics:
| Component | Cost Range |
|---|---|
| 400W solar panels (2x 200W) | $300-600 |
| 100Ah lithium battery | $300-500 |
| 1000W inverter | $100-200 |
| MPPT charge controller | $100-200 |
Total: roughly $800-1,500 for a learning setup that can power lights, charge devices, and run small appliances. Not enough for a whole house, but enough to understand how it all works.
The full system math
Based on my usage (around 900 kWh/month), a full grid-tied system would run:
- System size needed: ~6-8 kW
- Installed cost: $12,000-20,000 (before any tax credits)
- Federal tax credit: 30% (so effectively $8,400-14,000 out of pocket)
- My monthly bill: ~$150
- Payback period: 5-8 years
That’s real money up front for savings that take years to materialize. Not a no-brainer, but not unreasonable either.
What I haven’t figured out yet
- Whether my roof is actually suitable (need to get someone out to look)
- How net metering works in my area and whether the utility makes it worthwhile
- Whether battery storage makes financial sense or if grid-tied is the way to go
- How much of this I can install myself vs. needing a professional
Where I’m at
Still researching. Taking notes. Getting quotes. I’ll post updates as this moves forward – including if I decide solar doesn’t make sense for my situation right now.
