Finance & Incentives

Federal Clean Energy Tax Credits (ITC)

Eligible homeowners and businesses may claim a federal clean energy tax credit on qualified solar purchases. The credit amount and rules are set by law and can change; we’ll confirm current eligibility and provide documentation. (We’re not tax advisors—please consult your CPA.)

State & Utility Rebates

Many states and utilities offer limited-fund rebates or bill credits for new solar and storage installs. Availability, funding windows, and amounts vary by ZIP code; we check programs and handle the paperwork while funds last.

Net Metering & Export Credits

Depending on your utility, excess solar sent to the grid earns bill credits via net metering or export credit programs. Policies differ by service area; we guide metering, interconnection, inspections, and Permission-to-Operate (PTO).

Property & Sales Tax Relief

Some states exempt solar equipment from sales tax and/or offer property tax relief so added value from solar isn’t penalized. We identify applicable exemptions and prepare supporting documentation with your install package.

Solar Loans, Leases & PPAs

Choose from cash purchase, fixed-rate solar loans, or $0-down leases/PPAs. We compare ownership vs. third-party options, model payments and bill savings, and help you select the best fit for your goals and credit profile.

Battery Incentives & Rate Plans

Where available, storage rebates and demand-response programs can reduce battery costs. We also configure batteries for time-of-use (TOU) and demand charge reduction to lower bills and provide backup during outages.

Community Solar & Income-Eligible Support

If rooftop solar isn’t a fit, subscription-based community solar and income-qualified assistance may be available in your state. We’ll check local availability and outline how subscriptions and bill credits work.

Business Incentives & Depreciation

Commercial customers may benefit from accelerated depreciation (e.g., MACRS) and other business incentives. We coordinate with your tax professional and provide cost basis and commissioning documents for filings.

We purchased our new home two months ago and knew immediately that we needed to put solar on it. After a lot of research, I found SPN. They certainly live up to their reputations; from the introduction to the installation, the process has been apparent, and all project details have been clearly defined, discussed, and executed exactly how I was told.
