Real Case Studies of How Homeowners Are Saving 40 to 50 Percent on Energy Bills
If you’re a homeowner in Clovis thinking about going solar, there’s one thing you really want to know, how much will this actually save me?
At Supreme Solar and Electric, we’ve helped hundreds of homeowners take control of their energy bills by designing solar systems that fit their lifestyle, usage, and long-term goals. In this post, we’re going to walk you through real-world “before and after” solar transformations from small to large, including actual PG&E bill savings, battery setups, ROI timelines, and even a bonus case study on a custom elevated ground mount in Clovis.
Let’s jump into it.
Small System: 15 Panels with One Tesla Powerwall
40% Monthly Savings, 6.5-Year ROI
For this smaller Clovis home, the homeowner was dealing with PG&E bills averaging $325 per month in the summer and around $200 in the winter. The home was roughly 1,400 square feet with a smaller HVAC system and relatively efficient appliances.
System Installed:
- 15 Q Cells 440W panels (6.6 kW DC total)
- One Tesla Powerwall 3
- Roof-mounted on composition shingle
- Whole-home backup using Tesla Backup Switch
System Cost:
- Financed at 5.99% for 25 years
- Monthly solar payment: $160
- Total system cost after tax credit: $17,600
ROI Breakdown:
- 40% savings compared to PG&E
- ROI achieved in 6.5 years with system payback
- Home now energy independent, especially during summer blackouts
Monitoring & Maintenance:
Homeowner checks the Tesla app monthly to confirm production and backup readiness. The CTs were installed cleanly in the main panel and energy flows are tracked daily.
Medium System: 26 Panels with Two Tesla Powerwalls
45% Monthly Savings, 6-Year ROI
This was a family of four in a 2,300 square foot home. They had central air, two refrigerators, and a pool pump running during summer. Their PG&E bill averaged $500 in summer and around $350 during the off-season.
System Installed:
- 26 Jinko 440W panels (11.44 kW DC total)
- Two Tesla Powerwalls
- Roof-mounted, W Tile roof
- Tesla backup switch meter collar for whole home backup
System Cost:
- Cash purchase: $37,800 before tax credit
- Tax credit of 30% = $11,340
- Net cost: $26,460
ROI Breakdown:
- Monthly savings of $225 to $300
- Breakeven in just under 6 years
- System covers 120% of their annual usage to account for long-term degradation and EV charging down the road
Backup Capabilities:
With two Tesla batteries and the backup switch, this home can run essential loads plus a few extras like the fridge, lights, outlets, modem, and garage door for 24 to 48 hours depending on usage.
Large System: 22 kW With 40 kWh Battery Storage
50% Monthly Savings | Composite Shingle Roof | Flush Comp Mounts
Our third project is a great example of what a full-scale solar transformation looks like for larger homes with high usage — typically over 2,500 square feet, with pools, EVs, or large families.
System Specs:
- 22 kW solar system
- Jinko 440 watt panels (approximately 50 panels)
- 4 Neovolta NV10 batteries providing 40 kWh of total backup
- Flush-mounted on composite shingle roof
- Installed with IronRidge racking and flashings
- System financed with no money down through a local credit union
Before Solar:
- Monthly PG&E bill: $950
- Annual electric spend: $11,400
After Solar:
- Solar loan payment: $475/month
- Annual savings: $5,700/year
- 50% monthly savings from day one
Financing Details:
This customer used credit union financing with $0 down and a 5.99% APR over 25 years. After applying the 30% federal tax credit, their net system cost came out to around $87,000, and their loan payment came in at $475 per month.
Not only are they saving money immediately, but they also now have whole-home backup with 40 kWh of battery storage, keeping the lights on during outages and providing peace of mind.
Bonus Case Study: Elevated Ground Mount With 300-Foot Trench
Custom Build, Long-Term Energy Independence
This was a unique system in rural Clovis where the homeowner wanted solar, but didn’t want it on the roof. They also had a large open field that could double as a shaded area for livestock and farm equipment.
Project Highlights:
- 24 panels on an elevated ground mount, 10 feet off the ground
- Trench ran 300 feet underground to the battery location near the home
- Two SolarEdge Home batteries
- Full permitting, inspection, and PTO completed
Pre-Solar Utility Cost:
- $550 to $600 per month, no access to CARE discount
Final Setup:
- 10.56 kW solar array
- 20 kWh of storage capacity
- SolarEdge HD-Wave inverter with optimizers
- Main panel tie-in with AC coupling
Results:
- Monthly savings of $270 to $320 depending on the season
- ROI estimate: 6.2 years
- Custom shade structure now provides dual value — utility and comfort
Key Takeaways From These Clovis Case Studies
1. Savings Scale With System Size
As usage increases, solar ROI improves because you’re offsetting more high-cost PG&E electricity. A larger system also means a larger tax credit and a better cost-per-watt overall.
2. Battery Storage Adds Flexibility
Each of these case studies included batteries — from one Tesla to four Neovolta units. This ensures resilience during outages, peak rate avoidance, and energy security in a region known for high summer heat and blackouts.
3. The ROI Is Real
All of these homeowners are seeing savings between 40% and 50% on their electric bills. And because PG&E rates keep going up, these savings will only improve year after year.
4. Solar Can Be Financed or Prepaid
Whether you want to own the system outright or finance it and pay no money up front, there are multiple ways to make solar affordable in year one.
5. Custom Designs Matter
From carports to ground mounts, every home has a different layout and energy profile. Our team at Supreme Solar and Electric specializes in tailoring the system to your actual needs, not just a cookie-cutter solar package.
