Why Go Solar in Calexico?
- ●High sun exposure: Calexico averages an estimated 6.5 peak sun hours per day — strong solar production potential year-round.
- ●High IID rates: IID (Imperial Irrigation District) customers pay an estimated $0.16/kWh, making solar economics strong. Imperial Irrigation District (IID), a municipal utility, serves all of Imperial County at ~$0.16/kWh — among the lowest residential rates in California. Despite low rates, solar provides value through backup power during extreme heat outages, energy independence, and resilience during desert heat waves (110F+ common). The extreme heat drives high cooling loads that solar can offset.
- ●Federal tax credit: The 30% federal solar Investment Tax Credit (ITC) is currently available for systems installed on primary residences. Consult a tax professional for your specific situation.
- ●Home value: Studies suggest homes with owned solar systems sell for more than comparable homes without — though results vary by market.
