This article details a year-long review and return on investment (ROI) analysis of a solar panel installation on a Palm Springs Airbnb. The author invested $20,000 in a 20-panel system, aiming to reduce electricity costs and potentially generate income by selling excess energy back to the grid. The analysis covers the initial installation, actual energy production compared to projections, and a detailed breakdown of monthly and annual electricity bill savings. Key factors considered include the impact of weather conditions, energy consumption patterns, and the effectiveness of the Net Energy Metering (NEM) 2.0 program.The author shares a comprehensive evaluation of their experience, encompassing both the financial aspects and the practical considerations of integrating solar power into their property. This includes a calculation of the payback period, projected long-term savings (both with and without inflation), and a candid assessment of the financial gains from selling surplus energy. The article offers valuable insights for those considering a similar investment, highlighting the importance of local energy costs, sunlight availability, and personal energy consumption habits in determining the overall ROI of a solar panel system.
Pros And Cons
- Decreased electricity bill by approximately 60%, from an average of $620 to $253 per month.
- Significant yearly savings of around $4,500.
- Projected savings of tens of thousands of dollars over 30 years, potentially reaching six figures or more considering inflation.
- Initial investment cost of $20,000.
- Did not eliminate electricity bills completely; still incurred fixed fees and some electricity costs.
- Smaller system size than initially needed resulting in still having some electricity bills.
- Selling excess energy back to the grid yielded less income than anticipated; only approximately $700 for the year.

Initial Investment and System Setup
My solar panel journey began a year ago with a $20,000 investment in a 20-panel system for my Palm Springs Airbnb. This included all necessary electrical work and a solar inverter. I opted against a battery due to their high cost, a decision I'll analyze later.
The system's capacity is about what could fit on the roof of my relatively small house. While initially projected to produce 13,000 kWh annually, actual output was closer to 12,000 kWh, likely due to unusually rainy weather.
It's crucial to understand that even with solar panels, you're still connected to the grid and will incur monthly fixed fees and charges for any energy consumed beyond your solar generation. A common misconception is that solar eliminates all electricity bills, which isn't accurate.
Electricity Bill Savings Before and After Solar
Before solar, my monthly electricity bills ranged significantly, peaking at $892 in June 2022. The high cost reflected the hot desert climate, necessitating frequent AC use and energy consumption by the pool pump and hot tub.
After installing the solar panels, the bills drastically reduced. While January's bill only partially reflected solar's impact, February marked a significant change, dropping from $557 to $280 – a 50% decrease.
Monthly bills generally stayed below $300, averaging a 60% reduction compared to 2022. While there were minor variations throughout the year, the savings remained consistently substantial.
Return on Investment (ROI) and Long-Term Savings
The annual electricity cost dropped from $7400 to an estimated $2916, a remarkable $4500 savings. This translates to a 4.4-year payback period for the initial $20,000 investment.
Projecting over 30 years, the total savings are estimated at $133,000 (without inflation) and a staggering $212,000 when inflation is factored in. This underscores the long-term financial benefits of the solar panel installation.
This significant return on investment makes the initial expense worthwhile, particularly given the environmental advantages of renewable energy.
Selling Excess Energy Back to the Grid
I applied under NEM 2.0, allowing me to sell excess energy back to the grid at the same rate I buy it. However, the impact was less substantial than anticipated.
Despite expectations of higher sales during summer months due to longer days and lower energy consumption at the property, the high energy demands of the pool pump, hot tub, and AC negated this. I only made about $700 for the year.
This experience demonstrates the importance of considering your energy usage and climate when assessing the potential benefits of selling excess solar energy back to the grid.
Overall Conclusion: Is Solar Worth It?
The decision to install solar panels depends heavily on several factors: local electricity prices, sunlight availability, and the length of homeownership. In regions with high electricity costs and abundant sunshine, the return on investment becomes more compelling.
My experience demonstrates significant long-term financial benefits. While the impact of selling excess energy back to the grid wasn't as impactful as I'd hoped, the overall savings were substantial and exceeded expectations.
If you plan on staying in your home for an extended period, and your location benefits from ample sunshine and high energy costs, solar panels can be a worthwhile investment.
