Solar for AllSolar for All

1. Allow ALL residential customers to offset their bill – just like homeowners already can – with power generated by equipment they own at “solar farms”

2. Allow solar farm customers the option to lease their equipment – just like homeowners already can

3. Authorize Remote Net Metering for solar farm customers

What is What is Remote Net Metering?Remote Net Metering?

Energy consumption measured by one meter

Energy generation measured by another meter

Meters separated by miles, not feetGeneration subtracted from

consumption to determine the bill

13

Example: JanuaryExample: January

The Gomez family used $88 of electricity in their apartment

Their portion of the solar farmgenerated $30 of electricity

Their net bill is $58

14

Example: JulyExample: July

They used $65 of electricity

Their portion of the solar farm generated $115 of electricity

This gives them a credit of $50 for the month

2. Publicly Owned Utilities, $784 Million, 700 mW, all systems in POU areas

3. CEC: NSHP program, $400 Million, 360 mW, IOU territory, new homes

Total: $3,351 Million, 3,000 mW

Eligibility for 30% tax creditEligibility for 30% tax credit

ITC eligibility for customer-owned equipment at a Solar Farm is questionable

“Qualified solar electric property expenditure" means an expenditure for property which uses solar energy to generate electricity for use in a dwelling unit located in the United States and used as a residence by the taxpayer.
