What Robbins Energy Reviews in Your Proposal
A solar proposal contains a lot of information. We help you understand what matters — and what to ask before signing.
System Size (kW)
Is the system sized correctly for your actual usage?
Estimated Annual Production
Do the production estimates match your roof's real sun exposure?
Solar Panel Manufacturer
What brand and efficiency rating are the panels?
Inverter Technology
String inverter, microinverters, or power optimizers — each has trade-offs.
Battery Options
Is battery storage included? What capacity and backup duration?
Warranty Coverage
Panel, inverter, and workmanship warranties vary significantly.
Monitoring Features
How will you track production and catch problems early?
Price Per Watt
The most useful apples-to-apples comparison across proposals.
Financing Terms
Cash, loan, or lease — each has different long-term implications.
Why a Second Opinion Makes Sense
Confirm System Sizing
An undersized system won't offset your bill. An oversized system costs more than necessary. Proper sizing depends on your actual 12-month usage, roof orientation, and shading.
Understand Production Estimates
Production estimates vary based on assumptions. We review the methodology and compare it against local irradiance data for your specific address.
Compare Equipment Options
Solar panels, inverters, and batteries vary in performance, warranty terms, and suitability for Central Valley conditions. We help you understand the equipment in your proposal and what options are available.
Review Long-Term Ownership Costs
Warranties, monitoring, and service availability matter over a 25-year system life. We help you understand what happens if something needs repair.

NEM 2.0 vs NEM 3.0 — What It Means for Your Proposal
NEM 2.0
Systems interconnected before April 15, 2023 are grandfathered on NEM 2.0 for 20 years. If you have an existing system, your export rate is protected.
NEM 3.0
New systems interconnected after April 15, 2023 are on NEM 3.0. Export rates are lower, which means battery storage has a stronger financial case.
Battery Storage Under NEM 3.0
With NEM 3.0, storing solar energy and using it during peak evening hours (4–9 PM) is more valuable than exporting it. A properly sized battery can significantly improve your system's economics.
