Let’s take a look at a residential single-family home in California. This site pays an average of $0.18 /kWh for electricity and consumes an average of 8,300 /kWh per year. This home primarily operates during the morning and evening and has an HVAC unit and one LVL 2 EV charger located at the site.

Here is the projected energy usage model for this site.

System Sizing

For this location there is enough roof space and minimal shading which enabled us to design in an ideal 6.6 kW solar system for this location.

Equipment Overview:

    • 21 Panels Rated at 315 W
    • Solar Edge Grid Tied Inverter with paired DC Optimizers
    • Prop OS Base Main Panel Monitoring Sensor
    • Racking & Miscellaneous Equipment

After running the site layout through design software, we were able to come up with the following annual estimated performance of 8,610 kWh /Year. Which should offset 104% of this property’s energy needs annually.

Industry Standard Purchase Offer

Quotes received from other providers for the same system size came in as low as $20,450 [$14,315 with 30% ITC] to have this site permitted, installed and activated. Which yields an estimated 9-year payback period for this system

Ongoing annual monitoring and O&M comes to $200 /Year to keep site maintained.

Industry Standard PPA Offer

Of the providers asked to quote the site the best terms received are listed below

To run an example PPA offering:

    • Priced at $0.16 /kWh
    • Term length 20 years
    • No breaking contract, liable for full contract value
    • No upfront cost

This brings your total out of pocket expense on a PPA to $27,552 over the 20-year period. Your monthly expense for this solar system would be $114.8.  

What is holding homeowners back?

Purchase Option Negatives:

    • Choosing the right technology from the right manufacturer
    • Unable to modify or change system overtime as energy needs change
    • Required to have new roof before install, requires high level of thought and potential heavy expense

PPA Option Negatives:

    • Guaranteed Long Term Agreement
    • Typically results in a Lien taken out on the property
    • Puts personal credit on the line
    • No way to break contract easily, especially if selling the property
    • Purchasing provides far more economic incentive and flexibility

Overall between a PPA and purchasing – purchasing the hardware is the better option for residential property owners as financing terms currently are structured like a mortgage which is limiting and not the ideal way for owners to adopt renewables. Nonetheless, making a heavy upfront purchase puts property owner in a position requiring a heavy amount of research and due diligence which can take a lot of time away from other critical renovations and property upgrades that may have better opportunity costs.

Conclusion & Summary

In conclusion if you are looking into renewables or have been deterred by an industry that has designed its offering to maximize tax incentives or building utility scale power plants only then you can see that a subscription from TouchLight can be a viable alternative to help maximize the benefit of implementing an energy generation technology like solar.

This is primarily because you spend less money with TouchLight as you are extended wholesale level rates, given access to full building energy automation software free with your subscription, access to upgrades and modifying your system overtime and highly flexible contracts.
